Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Overview The accompanying Consolidated Financial Statements include the accounts of Unity Bancorp, Inc. (the “Parent Company”) and its wholly-owned subsidiary, Unity Bank (the “Bank” or when consolidated with the Parent Company, the “Company”). All significant intercompany balances and transactions have been eliminated in consolidation. Unity Bancorp, Inc. is a bank holding company incorporated in New Jersey and registered under the Bank Holding Company Act of 1956, as amended. Its wholly-owned subsidiary, the Bank, is chartered by the New Jersey Department of Banking and Insurance. The Bank provides a full range of commercial and retail banking services through eighteen branch offices located in Bergen, Hunterdon, Middlesex, Somerset, Union and Warren counties in New Jersey and Northampton County in Pennsylvania. These services include the acceptance of demand, savings, and time deposits and the extension of consumer, real estate, Small Business Administration (“SBA”) and other commercial credits. Unity Bank has nine wholly-owned subsidiaries: Unity Investment Services, Inc., AJB Residential Realty Enterprises, Inc., AJB Commercial Realty, Inc., MKCD Commercial, Inc., JAH Commercial, Inc., UB Commercial LLC, ASBC Holdings LLC, Unity Property Holdings 1, Inc., and Unity Property Holdings 2, Inc. Unity Investment Services, Inc. is used to hold and administer part of the Bank’s investment portfolio. The other subsidiaries hold, administer and maintain the Bank’s other real estate owned (“OREO”) properties. Unity Investment Services, Inc. has one subsidiary, Unity Delaware Investment 2, Inc., which has one subsidiary, Unity NJ REIT, Inc. Unity NJ REIT, Inc. was formed in 2013 to hold loans. The Company has two wholly-owned subsidiaries: Unity (NJ) Statutory Trust II and Unity Risk Management, Inc. For additional information on Unity (NJ) Statutory Trust II, see Note 9 to the Consolidated Financial Statements. Unity Risk Management, Inc. is the Company's captive insurance company that insures risks to the bank not insured by the traditional commercial insurance market. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Amounts requiring the use of significant estimates include the allowance for loan losses, valuation of deferred tax and servicing assets, the carrying value of loans held for sale and other real estate owned, the valuation of securities and the determination of other-than-temporary impairment for securities and fair value disclosures. Actual results could differ from those estimates. 10 Percent Stock Dividend Paid On September 30, 2016 a 10 percent stock dividend was paid to all shareholders of record as of September 15, 2016. All share information has been adjusted as necessary to account for this dividend. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks, federal funds sold and interest-bearing deposits. Securities The Company classifies its securities into two categories, available for sale and held to maturity. Securities that are classified as available for sale are stated at fair value. Unrealized gains and losses on securities available for sale are generally excluded from results of operations and are reported as other comprehensive income, a separate component of shareholders’ equity, net of taxes. Securities classified as available for sale include securities that may be sold in response to changes in interest rates, changes in prepayment risks or for asset/liability management purposes. The cost of securities sold is determined on a specific identification basis. Gains and losses on sales of securities are recognized in the Consolidated Statements of Income on the date of sale. Securities are classified as held to maturity based on management’s intent and ability to hold them to maturity. Such securities are stated at cost, adjusted for unamortized purchase premiums and discounts using the level yield method. If transfers between the available for sale and held to maturity portfolios occur, they are accounted for at fair value and unrealized holding gains and losses are accounted for at the date of transfer. For securities transferred to available for sale from held to maturity, unrealized gains or losses as of the date of the transfer are recognized in other comprehensive income (loss), a separate component of shareholders’ equity. For securities transferred into the held to maturity portfolio from the available for sale portfolio, unrealized gains or losses as of the date of transfer continue to be reported in other comprehensive income (loss), and are amortized over the remaining life of the security as an adjustment to its yield, consistent with amortization of the premium or accretion of the discount. For additional information on securities, see Note 3 to the Consolidated Financial Statements. Other-Than-Temporary Impairment The Company has a process in place to identify debt securities that could potentially incur credit impairment that is other-than-temporary. This process involves monitoring late payments, pricing levels, downgrades by rating agencies, key financial ratios, financial statements, revenue forecasts and cash flow projections as indicators of credit issues. Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concern warrants such evaluation. This evaluation considers relevant facts and circumstances in evaluating whether a credit or interest rate-related impairment of a security is other-than-temporary. Relevant facts and circumstances considered include: (1) the extent and length of time the fair value has been below cost; (2) the reasons for the decline in value; (3) the financial position and access to capital of the issuer, including the current and future impact of any specific events and (4) for fixed maturity securities, the intent to sell a security or whether it is more likely than not the Company will be required to sell the security before the recovery of its amortized cost which, in some cases, may extend to maturity. For debt securities that are considered other-than-temporarily impaired where management has no intent to sell and the Company has no requirement to sell prior to recovery of its amortized cost basis, the amount of the impairment 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 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. For debt securities where management has the intent to sell, the amount of the impairment is reflected in earnings as realized losses. The present value of expected future cash flows is determined using the best estimate cash flows discounted at the effective interest rate implicit to the security at the date of purchase or the current yield to accrete an asset-backed or floating rate security. The methodology and assumptions for establishing the best estimate cash flows vary depending on the type of security. The asset-backed securities cash flow estimates are based on bond specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity and prepayment speeds and structural support, including subordination and guarantees. The corporate bond cash flow estimates are derived from scenario-based outcomes of expected corporate restructurings or the disposition of assets using bond specific facts and circumstances including timing, security interests and loss severity. Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has 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 advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Loans Loans Held for Sale Loans held for sale represent the guaranteed portion of SBA loans and are reflected at the lower of aggregate cost or market value. The Company originates loans to customers under an SBA program that historically has provided for SBA guarantees of up to 90 percent of each loan. The Company generally sells the guaranteed portion of its SBA loans to a third party and retains the servicing, holding the nonguaranteed portion in its portfolio. The net amount of loan origination fees on loans sold is included in the carrying value and in the gain or loss on the sale. When sales of SBA loans do occur, the premium received on the sale and the present value of future cash flows of the servicing assets are recognized in income. All criteria for sale accounting must be met in order for the loan sales to occur; see details under the “Transfers of Financial Assets” heading above. Servicing assets represent the estimated fair value of retained servicing rights, net of servicing costs, at the time loans are sold. Servicing assets are amortized in proportion to, and over the period of, estimated net servicing revenues. Impairment is evaluated based on stratifying the underlying financial assets by date of origination and term. Fair value is determined using prices for similar assets with similar characteristics, when available, or based upon discounted cash flows using market-based assumptions. Any impairment, if temporary, would generally be reported as a valuation allowance. Serviced loans sold to others are not included in the accompanying Consolidated Balance Sheets. Income and fees collected for loan servicing are credited to noninterest income when earned, net of amortization on the related servicing assets. For additional information on servicing assets, see Note 4 to the Consolidated Financial Statements. Loans Held for Investment Loans held for investment are stated at the unpaid principal balance, net of unearned discounts and deferred loan origination fees and costs. In accordance with the level yield method, loan origination fees, net of direct loan origination costs, are deferred and recognized over the estimated life of the related loans as an adjustment to the loan yield. Interest is credited to operations primarily based upon the principal balance outstanding. Loans are reported as past due when either interest or principal is unpaid in the following circumstances: fixed payment loans when the borrower is in arrears for two or more monthly payments; open end credit for two or more billing cycles; and single payment notes if interest or principal remains unpaid for 30 days or more. Nonperforming loans consist of loans that are not accruing interest as a result of principal or interest being delinquent for a period of 90 days or more or when the ability to collect principal and interest according to the contractual terms is in doubt (nonaccrual loans). When a loan is classified as nonaccrual, interest accruals are discontinued and all past due interest previously recognized as income is reversed and charged against current period earnings. Generally, until the loan becomes current, any payments received from the borrower are applied to outstanding principal until such time as management determines that the financial condition of the borrower and other factors merit recognition of a portion of such payments as interest income. Loans may be returned to an accrual status when the ability to collect is reasonably assured and when the loan is brought current as to principal and interest. Loans are charged off when collection is sufficiently questionable and when the Company can no longer justify maintaining the loan as an asset on the balance sheet. Loans qualify for charge-off when, after thorough analysis, all possible sources of repayment are insufficient. These include: 1) potential future cash flows, 2) value of collateral, and/or 3) strength of co-makers and guarantors. All unsecured loans are charged off upon the establishment of the loan’s nonaccrual status. Additionally, all loans classified as a loss or that portion of the loan classified as a loss is charged off. All loan charge-offs are approved by the Board of Directors. Troubled debt restructurings ("TDRs") occur when a creditor, for economic or legal reasons related to a debtor’s financial condition, grants a concession to the debtor that it would not otherwise consider. These concessions typically include reductions in interest rate, extending the maturity of a loan, or a combination of both. Interest income on accruing TDRs is credited to operations primarily based upon the principal amount outstanding, as stated in the paragraphs above. The Company evaluates its loans for impairment. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. The Company has defined impaired loans to be all TDRs and nonperforming loans. Impairment is evaluated in total for smaller-balance loans of a similar nature (consumer and residential mortgage loans), and on an individual basis for all other loans. Impairment of a loan is measured based on the present value of expected future cash flows, discounted at the loan's effective interest rate, or as a practical expedient, based on a loan’s observable market price or the fair value of collateral, net of estimated costs to sell, if the loan is collateral-dependent. If the value of the impaired loan is less than the recorded investment in the loan, the Company establishes a valuation allowance, or adjusts existing valuation allowances, with a corresponding charge to the provision for loan losses. For additional information on loans, see Note 4 to the Consolidated Financial Statements. Allowance for Loan Losses and Reserve for Unfunded Loan Commitments The allowance for loan losses is maintained at a level management considers adequate to provide for probable loan losses as of the balance sheet date. The allowance is increased by provisions charged to expense and is reduced by net charge-offs. The level of the allowance is based on management’s evaluation of probable losses in the loan portfolio, after consideration of prevailing economic conditions in the Company’s market area, the volume and composition of the loan portfolio, and historical loan loss experience. The allowance for loan losses consists of specific reserves for individually impaired credits and TDRs, reserves for nonimpaired loans based on historical loss factors adjusted for general economic factors and other qualitative risk factors such as changes in delinquency trends, industry concentrations or local/national economic trends. This risk assessment process is performed at least quarterly, and, as adjustments become necessary, they are realized in the periods in which they become known. Although management attempts to maintain the allowance at a level deemed adequate to provide for probable losses, future additions to the allowance may be necessary based upon certain factors including changes in market conditions and underlying collateral values. In addition, various regulatory agencies periodically review the adequacy of the Company’s allowance for loan losses. These agencies may require the Company to make additional provisions based on judgments about information available at the time of the examination. The Company maintains a reserve for unfunded loan commitments at a level that management believes is adequate to absorb estimated probable losses. Adjustments to the reserve are made through other expenses and applied to the reserve which is classified as other liabilities. For additional information on the allowance for loan losses and reserve for unfunded loan commitments, see Note 5 to the Consolidated Financial Statements. Premises and Equipment Land is carried at cost. All other fixed assets are carried at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The useful life of buildings is not to exceed 30 years ; furniture and fixtures is generally 10 years or less, and equipment is 3 to 5 years . Leasehold improvements are depreciated over the life of the underlying lease. For additional information on premises and equipment, see Note 6 to the Consolidated Financial Statements. Bank Owned Life Insurance The Company purchased life insurance policies on certain members of management. Bank owned life insurance is recorded at its cash surrender value or the amount that can be realized. Federal Home Loan Bank Stock Federal law requires a member institution of the Federal Home Loan Bank system to hold stock of its district FHLB according to a predetermined formula. The stock is carried at cost. Management reviews the stock for impairment based on the ultimate recoverability of the cost basis in the stock. The stock’s value is determined by the ultimate recoverability of the par value rather than by recognizing temporary declines. Management considers such criteria as the significance of the decline in net assets, if any, of the FHLB, the length of time this situation has persisted, commitments by the FHLB to make payments required by law or regulation, the impact of legislative and regulatory changes on the customer base of the FHLB and the liquidity position of the FHLB. Other Real Estate Owned Other real estate owned is recorded at the fair value, less estimated costs to sell at the date of acquisition, with a charge to the allowance for loan losses for any excess of the loan carrying value over such amount. Subsequently, OREO is carried at the lower of cost or fair value, as determined by current appraisals. Certain costs that increase the value or extend the useful life in preparing properties for sale are capitalized to the extent that the appraisal amount exceeds the carry value, and expenses of holding foreclosed properties are charged to operations as incurred. Appraisals The Company requires current real estate appraisals on all loans that become OREO or in-substance foreclosure, loans that are classified substandard, doubtful or loss, or loans that are over $ 100,000 and nonperforming. Prior to each balance sheet date, the Company values impaired collateral-dependent loans and OREO based upon a third party appraisal, broker's price opinion, drive by appraisal, automated valuation model, updated market evaluation, or a combination of these methods. The amount is discounted for the decline in market real estate values (for original appraisals), for any known damage or repair costs, and for selling and closing costs. The amount of the discount is dependent upon the method used to determine the original value. The original appraisal is generally used when a loan is first determined to be impaired. When applying the discount, the Company takes into consideration when the appraisal was performed, the collateral’s location, the type of collateral, any known damage to the property and the type of business. Subsequent to entering impaired status and the Company determining that there is a collateral shortfall, the Company will generally, depending on the type of collateral, order a third party appraisal, broker's price opinion, automated valuation model or updated market evaluation. Subsequent to receiving the third party results, the Company will discount the value 6 to 10 percent for selling and closing costs. Income Taxes The Company follows Financial Accounting Standards Board Accounting Standards Codification ("FASB ASC") Topic 740, “Income Taxes,” which prescribes a threshold for the financial statement recognition of income taxes and provides criteria for the measurement of tax positions taken or expected to be taken in a tax return. ASC 740 also includes guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition of income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the enacted tax rates applicable to taxable income for the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation reserves are established against certain deferred tax assets when it is more likely than not that the deferred tax assets will not be realized. Increases or decreases in the valuation reserve are charged or credited to the income tax provision. When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that ultimately would be sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. The evaluation of a tax position taken is considered by itself and not offset or aggregated with other positions. Tax positions that meet the more likely than not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. Interest and penalties associated with unrecognized tax benefits are recognized in income tax expense on the income statement. For additional information on income taxes, see Note 15 to the Consolidated Financial Statements. Net Income Per Share Basic net income per common share is calculated as net income available to common shareholders divided by the weighted average common shares outstanding during the reporting period. Diluted net income per common share is computed similarly to that of basic net income per common share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if all potentially dilutive common shares, principally stock options, were issued during the reporting period utilizing the Treasury stock method. However, when a net loss rather than net income is recognized, diluted earnings per share equals basic earnings per share. For additional information on net income per share, see Note 16 to the Consolidated Financial Statements. Stock-Based Compensation The Company accounts for its stock-based compensation awards in accordance with FASB ASC Topic 718, “Compensation – Stock Compensation,” which requires recognition of compensation expense related to stock-based compensation awards over the period during which an employee is required to provide service for the award. Compensation expense is equal to the fair value of the award, net of estimated forfeitures, and is recognized over the vesting period of such awards. For additional information on the Company’s stock-based compensation, see Note 18 to the Consolidated Financial Statements. Fair Value The Company follows FASB ASC Topic 820, “Fair Value Measurement and Disclosures,” which provides a framework for measuring fair value under generally accepted accounting principles. For additional information on the fair value of the Company’s financial instruments, see Note 19 to the Consolidated Financial Statements. Other Comprehensive Income Other comprehensive income consists of the change in unrealized gains (losses) on SERP, securities available for sale and swap related items that were reported as a component of shareholders’ equity, net of tax. For additional information on other comprehensive income, see Note 11 to the Consolidated Financial Statements. Advertising The Company expenses the costs of advertising in the period incurred. Dividend Restrictions Banking regulations require maintaining certain capital levels that may limit the dividends paid by the Bank to the holding company or by the holding company to the shareholders. Operating Segments While management monitors the revenue streams of its various products and services, operating results and financial performance are evaluated on a company-wide basis. The Company’s management uses consolidated results to make operating and strategic decisions. Accordingly, there is only one reportable segment. Recent Accounting Pronouncements ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 replaced almost all existing revenue recognition guidance in current U.S. GAAP. The Company’s main source of revenue is comprised of net interest income on interest earning assets and liabilities and non-interest income. The scope of the guidance explicitly excludes net interest income as well as many other revenues for financial assets and liabilities including loans, leases, securities, and derivatives. As such, the Company does not expect the guidance to have a material impact on its financial statements. Under current U.S. GAAP, when full consideration is not expected and financing is required by the buyer to purchase the property, there are very prescriptive requirements in determining when foreclosed real estate property sold by an institution should be derecognized and a gain or loss be recognized. The new guidance that will be applied to these sales is more principles based. For example, as it pertains to the criteria for determining how a contract should be accounted for under the new guidance, judgment will need to be exercised in evaluating if: (a) a commitment on the buyer’s part exists, (b) collection is probable in circumstances where the initial investment is minimal and (c) the buyer has obtained control of the asset, including the significant risks and rewards of the ownership. If there is no commitment on the buyer’s part, collection is not probable or the buyer has not obtained control of the asset, then a gain cannot be recognized under the new guidance. The initial investment requirement for the buyer along with the various methods for profit recognition are no longer applicable when the new guidance goes into effect. The Company will revise its current policy on the recognition and measurement of gain on sale of other real estate owned to be consistent with the new guidance, but does not expect the new guidance to have a significant impact on the consolidated financial statements of the Company when adopted. For deposit-related fees, considering the straightforward nature of the arrangements with the Company’s deposits customers, the Company does not expect the recognition and measurement outcomes of deposit-related fees to be significant differently under the new guidance compared to current U.S. GAAP. ASU 2014-09 was to be effective for interim and annual periods beginning after December 15, 2016 and was to be applied on either a modified retrospective or full retrospective basis. In August 2015, the FASB issued ASU 2015-14 which defers the original effective date for all entities by one year. Public business entities should apply the guidance in ASU 2015-14 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company does not expect this ASU to have a material impact on the Company’s consolidated financial statements when adopted on January 1, 2018 using the modified retrospective basis. ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10) – Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This eliminates the available for sale classification of accounting for equity securities and adjusts the fair value disclosures for financial instruments carried at amortized cost such that the disclosed fair values represent an exit price as opposed to an entry price. This update requires that equity securities be carried at fair value on the balance sheet and any periodic changes in value will be adjusted through the income statement. A practical expedient is provided for equity securities without a readily determinable fair value, such that these securities can be carried at cost less any impairment. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company has formed a committee to evaluate the fair value measurements of financial instruments for disclosure purposes. ASU 2016-02, “Leases (Topic 842)”. ASU 2016-02 was issued in three parts: (a) Section A, “Leases: Amendments to the FASB Accounting Standards Codification®,” (b) Section B, “Conforming Amendments Related to Leases: Amendments to the FASB Accounting Standards Codification®,” and (c) Section C, “Background Information and Basis for Conclusions.” While both lessees and lessors are affected by the new guidance, the effects on lessees are much more significant. The update states that a lessee should recognize the assets and liabilities that arise from all leases with a term greater than 12 months. The core principle requires the lessee to recognize a liability to make lease payments and a "right-of-use" asset. The accounting applied by the lessor is relatively unchanged as the majority of operating leases should remain classified as operating leases and the income from them recognized, generally, on a straight-line basis over the lease term. The standards update also requires expanded qualitative and quantitative disclosures. For public business entities, ASC 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. ASC 2016-02 mandates a modified retrospective transition for all entities. The Company is currently evaluating the impact of the adoption of ASC 2016-02 on its consolidated financial statements. As of December 31, 2017, the Company had minimum noncancelable net operating lease payments of $1.2 million that are being evaluated. The implementation team is working on gathering all key lease data elements to meet the requirements of the new guidance. ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." ASU 2016-13 was issued to replace the incurred loss impairment methodology in current GAAP with an expected credit loss methodology and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses. Purchased credit impaired loans will receive an allowance account at the acquisition date that represents a component of the purchase price allocation. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses, with such allowance limited to the

Cash and Cash Equivalents [Abstract]
Restrictions on Cash	Restrictions on Cash Federal law requires depository institutions to hold reserves in the form of vault cash or, if vault cash is insufficient, in the form of a deposit maintained with a Federal Reserve Bank (“FRB”). The dollar amount of a depository institution's reserve requirement is determined by applying the reserve ratios specified in the FRB’s Regulation D to an institution's reservable liabilities. As of December 31, 2017 , the Company required $23 thousand of additional reserves to meet its reserve requirements. As of December 31, 2016 , the Company required $15 thousand of additional reserves to meet its reserve requirements. In addition, the Company’s contract with its current electronic funds transfer (“EFT”) provider requires a predetermined balance be maintained in a settlement account controlled by the provider equal to the Company’s average daily net settlement position multiplied by four days. The required balance was $ 156 thousand as of December 31, 2017 and 2016 . This balance can be adjusted periodically to reflect actual transaction volume and seasonal factors. As of December 31, 2017 , Unity Risk Management, Inc. had a total cash balance of $1.3 million , compared to $1.2 million at December 31, 2016 .

Investments in debt securities may be classified as held-to-maturity and measured at amortized cost in the statement of financial position only if the reporting enterprise has the positive intent and ability to hold those securities to maturity. Evidence of a significant deterioration in the issuer's creditworthiness is a circumstance in which the enterprise may change its intent to hold a certain security to maturity without calling into question its intent to hold other debt securities to maturity in the future. This event was isolated, nonrecurring, and unusual for the Company. Unrealized Losses The unrealized losses in each of the categories presented in the tables above are discussed in the paragraphs that follow: U.S. government sponsored entities and state and political subdivision securities: The unrealized losses on investments in these types of securities were caused by the increase in interest rate spreads or the increase in interest rates at the long end of the Treasury curve. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the par value of the investments. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be at maturity, the Company did not consider these investments to be other-than temporarily impaired as of December 31, 2017 . There was no other-than-temporary impairment on these securities at December 31, 2016 . Residential and commercial mortgage-backed securities: The unrealized losses on investments in mortgage-backed securities were caused by increases in interest rate spreads or the increase in interest rates at the long end of the Treasury curve. The majority of contractual cash flows of these securities are guaranteed by the Federal National Mortgage Association (FNMA), the Government National Mortgage Association (GNMA) and the Federal Home Loan Mortgage Corporation (FHLMC). It is expected that the securities would not be settled at a price significantly less than the par value of the investment. Because the decline in fair value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be at maturity, the Company did not consider these investments to be other-than-temporarily impaired as of December 31, 2017 or December 31, 2016 . Corporate and other securities: Included in this category are corporate debt securities, Community Reinvestment Act (“CRA”) investments, asset-backed securities, and one trust preferred security. The unrealized losses on corporate debt securities were due to widening credit spreads or the increase in interest rates at the long end of the Treasury curve and the unrealized losses on CRA investments were caused by decreases in the market prices of the shares. The Company evaluated the prospects of the issuers and forecasted a recovery period; and as a result determined it did not consider these investments to be other-than-temporarily impaired as of December 31, 2017 or December 31, 2016 . The unrealized loss on the trust preferred security was caused by an inactive trading market and changes in market credit spreads. At December 31, 2017 and December 31, 2016 , this category consisted of one single-issuer trust preferred security. The contractual terms do not allow the security to be settled at a price less than the par value. Because the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, which may be at maturity, the Company did not consider this security to be other-than-temporarily impaired as of December 31, 2017 or December 31, 2016 . Realized Gains and Losses Gross realized gains and losses on securities for the past two years are detailed in the table below: For the years ended December 31, (In thousands) 2017 2016 Available for sale: Realized gains $ 89 $ 302 Realized losses (61 ) (1 ) Total securities available for sale 28 301 Held to maturity: Realized gains 38 123 Realized losses (4 ) — Total securities held to maturity 34 123 Net gains on sales of securities $ 62 $ 424 The net realized gains are included in noninterest income in the Consolidated Statements of Income as net security gains. For 2017 and 2016 , gross realized gains on sales of securities amounted to $ 127 thousand and $ 425 thousand , respectively. There were $65 thousand of gross realized losses in 2017 , compared to a $1 thousand loss in 2016 . • The net gains during 2017 are attributed to the sale of three mortgage-backed securities with a total book value of $1.2 million and resulting gains of $71 thousand , the sale of one taxable municipal security with a book value of $529 thousand and resulting gains of $38 thousand , the call of two asset-backed securities totaling $3.5 million in book value, resulting in gains of $3 thousand , and the call of four municipal tax-exempt securites with a total book value of $500 thousand and resulting gains of $15 thousand , partially offset by the sale of two mortgage-backed securities with a book value of $1.6 million which resulted in a loss of $58 thousand , and the call of two corporate bonds with a book value of $3.0 million and resulting losses of $7 thousand . • The net gains during 2016 are attributed to the sale of fifteen municipal securities with a total book value of $6.4 million and resulting gains of $112 thousand , the sale of two SBA securities with a book value of $2.5 million and resulting gains of $12 thousand , the sale of thirteen equity securities totaling $515 thousand in book value, resulting in pre-tax gains of approximately $177 thousand , and the sale of five corporate bonds with a total book value of $8.5 million and resulting gains of $124 thousand , partially offset by the sale of one SBA security with a book value of $753 thousand which resulting in a loss of $1 thousand . Pledged Securities Securities with a carrying value of $20.8 million and $17.7 million at December 31, 2017 and December 31, 2016 , respectively, were pledged to secure Government deposits, secure other borrowings and for other purposes required or permitted by law.

Loans	Loans The following table sets forth the classification of loans by class, including unearned fees, deferred costs and excluding the allowance for loan losses for the past two years: (In thousands) December 31, 2017 December 31, 2016 SBA loans held for investment $ 43,999 $ 42,492 SBA 504 loans 21,871 26,344 Commercial loans Commercial other 82,825 58,447 Commercial real estate 469,696 422,418 Commercial real estate construction 54,473 28,306 Residential mortgage loans 365,145 289,093 Consumer loans Home equity 55,817 47,411 Consumer other 54,038 44,130 Total loans held for investment $ 1,147,864 $ 958,641 SBA loans held for sale 22,810 14,773 Total loans $ 1,170,674 $ 973,414 Loans are made to individuals as well as commercial entities. Specific loan terms vary as to interest rate, repayment, and collateral requirements based on the type of loan requested and the credit worthiness of the prospective borrower. Credit risk, excluding SBA loans, tends to be geographically concentrated in that a majority of the loan customers are located in the markets serviced by the Bank. As a preferred SBA lender, a portion of the SBA portfolio is to borrowers outside the Company’s lending area. However, during late 2008, the Company withdrew from SBA lending outside of its primary trade area, but continues to offer SBA loan products as an additional credit product within its primary trade area. Loan performance may be adversely affected by factors impacting the general economy or conditions specific to the real estate market such as geographic location and/or property type. A description of the Company's different loan segments follows: SBA Loans: SBA 7(a) loans, on which the SBA has historically provided guarantees of up to 90 percent of the principal balance, are considered a higher risk loan product for the Company than its other loan products. The guaranteed portion of the Company’s SBA loans is generally sold in the secondary market with the nonguaranteed portion held in the portfolio as a loan held for investment. SBA loans are for the purpose of providing working capital, financing the purchase of equipment, inventory or commercial real estate and for other business purposes. Loans are guaranteed by the businesses' major owners. SBA loans are made based primarily on the historical and projected cash flow of the business and secondarily on the underlying collateral provided. SBA 504 Loans: The SBA 504 program consists of real estate backed commercial mortgages where the Company has the first mortgage and the SBA has the second mortgage on the property. SBA 504 loans are made based primarily on the historical and projected cash flow of the business and secondarily on the underlying collateral provided. Generally, the Company has a 50 percent loan to value ratio on SBA 504 program loans at origination. Commercial Loans: Commercial credit is extended primarily to middle market and small business customers. Commercial loans are generally made in the Company’s market place for the purpose of providing working capital, financing the purchase of equipment, inventory or commercial real estate and for other business purposes. Loans will generally be guaranteed in full or for a meaningful amount by the businesses' major owners. Commercial loans are made based primarily on the historical and projected cash flow of the business and secondarily on the underlying collateral provided. Residential Mortgage and Consumer Loans: The Company originates mortgage and consumer loans including principally residential real estate, home equity lines and loans and consumer construction lines. Each loan type is evaluated on debt to income, type of collateral and loan to collateral value, credit history and Company relationship with the borrower. Inherent in the lending function is credit risk, which is the possibility a borrower may not perform in accordance with the contractual terms of their loan. A borrower’s inability to pay their obligations according to the contractual terms can create the risk of past due loans and, ultimately, credit losses, especially on collateral deficient loans. The Company minimizes its credit risk by loan diversification and adhering to credit administration policies and procedures. Due diligence on loans begins when the Company initiates contact regarding a loan with a borrower. Documentation, including a borrower’s credit history, materials establishing the value and liquidity of potential collateral, the purpose of the loan, the source of funds for repayment of the loan, and other factors, are analyzed before a loan is submitted for approval. The loan portfolio is then subject to on-going internal reviews for credit quality, as well as independent credit reviews by an outside firm. The Company's extension of credit is governed by the Credit Risk Policy which was established to control the quality of the Company's loans. These policies and procedures are reviewed and approved by the Board of Directors on a regular basis. Credit Ratings For SBA 7(a), SBA 504 and commercial loans, management uses internally assigned risk ratings as the best indicator of credit quality. A loan’s internal risk rating is updated at least annually and more frequently if circumstances warrant a change in risk rating. The Company uses a 1 through 10 loan grading system that follows regulatory accepted definitions. Pass: Risk ratings of 1 through 6 are used for loans that are performing, as they meet, and are expected to continue to meet, all of the terms and conditions set forth in the original loan documentation, and are generally current on principal and interest payments. These performing loans are termed “Pass”. Special Mention: Criticized loans are assigned a risk rating of 7 and termed “Special Mention”, as the borrowers exhibit potential credit weaknesses or downward trends deserving management’s close attention. If not checked or corrected, these trends will weaken the Bank’s collateral and position. While potentially weak, these borrowers are currently marginally acceptable and no loss of interest or principal is anticipated. As a result, special mention assets do not expose an institution to sufficient risk to warrant adverse classification. Included in “Special Mention” could be turnaround situations, such as borrowers with deteriorating trends beyond one year, borrowers in start up or deteriorating industries, or borrowers with a poor market share in an average industry. "Special Mention" loans may include an element of asset quality, financial flexibility, or below average management. Management and ownership may have limited depth or experience. Regulatory agencies have agreed on a consistent definition of “Special Mention” as an asset with potential weaknesses which, if left uncorrected, may result in deterioration of the repayment prospects for the asset or in the Bank’s credit position at some future date. This definition is intended to ensure that the “Special Mention” category is not used to identify assets that have as their sole weakness credit data exceptions or collateral documentation exceptions that are not material to the repayment of the asset. Substandard: Classified loans are assigned a risk rating of an 8 or 9, depending upon the prospect for collection, and deemed “Substandard”. A risk rating of 8 is used for borrowers with well-defined weaknesses that jeopardize the orderly liquidation of debt. The loan is inadequately protected by the current paying capacity of the obligor or by the collateral pledged, if any. Normal repayment from the borrower is in jeopardy, although no loss of principal is envisioned. There is a distinct possibility that a partial loss of interest and/or principal will occur if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified “Substandard”. A risk rating of 9 is used for borrowers that have all the weaknesses inherent in a loan with a risk rating of 8, with the added characteristic that the weaknesses make collection of debt in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Serious problems exist to the point where partial loss of principal is likely. The possibility of loss is extremely high, but because of certain important, reasonably specific pending factors that may work to strengthen the assets, the loans’ classification as estimated losses is deferred until a more exact status may be determined. Pending factors include proposed merger, acquisition, or liquidation procedures; capital injection; perfecting liens on additional collateral; and refinancing plans. Partial charge-offs are likely. Loss: Once a borrower is deemed incapable of repayment of unsecured debt, the risk rating becomes a 10, the loan is termed a “Loss”, and charged-off immediately. Loans to such borrowers are considered uncollectible and of such little value that continuance as active assets of the Bank is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off these basically worthless assets even though partial recovery may be affected in the future. For residential mortgage and consumer loans, management uses performing versus nonperforming as the best indicator of credit quality. Nonperforming loans consist of loans that are not accruing interest (nonaccrual loans) as a result of principal or interest being delinquent for a period of 90 days or more or when the ability to collect principal and interest according to the contractual terms is in doubt. These credit quality indicators are updated on an ongoing basis, as a loan is placed on nonaccrual status as soon as management believes there is sufficient doubt as to the ultimate ability to collect interest on a loan.

Loans past due 90 days or more and still accruing interest are not included in nonperforming loans and generally represent loans that are well collateralized and in a continuing process expected to result in repayment or restoration to current status. The risk of loss is difficult to quantify and is subject to fluctuations in collateral values, general economic conditions and other factors. The improved state of the economy has resulted in a substantial reduction in nonperforming loans and loan delinquencies. The Company values its collateral through the use of appraisals, broker price opinions, and knowledge of its local market. In response to the credit risk in its portfolio, the Company has increased staffing in its credit monitoring department and increased efforts in the collection and analysis of borrowers’ financial statements and tax returns.

Impaired Loans The Company has defined impaired loans to be all nonperforming loans and troubled debt restructurings. Management considers a loan impaired when, based on current information and events, it is determined that the Company will not be able to collect all amounts due according to the loan contract. The following tables provide detail on the Company’s loans individually evaluated for impairment with the associated allowance amount, if applicable, as of December 31, 2017 and December 31, 2016 : December 31, 2017 (In thousands) Unpaid principal balance Recorded investment Specific reserves With no related allowance: SBA loans held for investment (1) $ 135 $ 52 $ — SBA 504 loans — — — Commercial loans Commercial other 25 25 — Commercial real estate 43 43 — Total commercial loans 68 68 — Total impaired loans with no related allowance 203 120 — With an allowance: SBA loans held for investment (1) 748 553 194 SBA 504 loans — — — Commercial loans Commercial other — — — Commercial real estate 786 786 138 Total commercial loans 786 786 138 Total impaired loans with a related allowance 1,534 1,339 332 Total individually evaluated impaired loans: SBA loans held for investment (1) 883 605 194 SBA 504 loans — — — Commercial loans Commercial other 25 25 — Commercial real estate 829 829 138 Total commercial loans 854 854 138 Total individually evaluated impaired loans $ 1,737 $ 1,459 $ 332 (1) Balances are reduced by amount guaranteed by the SBA of $27 thousand at December 31, 2017 .

The following table presents the average recorded investments in impaired loans and the related amount of interest recognized during the time period in which the loans were impaired for the years ended December 31, 2017 and 2016 . The average balances are calculated based on the month-end balances of impaired loans. When the ultimate collectability of the total principal of an impaired loan is in doubt and the loan is on nonaccrual status, all payments are applied to principal under the cost recovery method, therefore no interest income is recognized. The interest recognized on impaired loans noted below represents accruing troubled debt restructurings only and nominal amounts of income recognized on a cash basis for well-collateralized impaired loans. For the years ended December 31, 2017 2016 (In thousands) Average recorded investment Interest income recognized on impaired loans Average recorded investment Interest income recognized on impaired loans SBA loans held for investment (1) $ 668 $ 47 $ 1,535 $ 14 SBA 504 loans 82 — 798 — Commercial loans Commercial other 25 — 607 38 Commercial real estate 685 43 1,198 59 Commercial real estate construction — — 272 — Total $ 1,460 $ 90 $ 4,410 $ 111 (1) Balances are reduced by the average amount guaranteed by the SBA of $318 thousand and $246 thousand for years ended December 31, 2017 and 2016 , respectively. Troubled Debt Restructurings The Company's loan portfolio includes certain loans that have been modified in a troubled debt restructuring (“TDR”). TDRs occur when a creditor, for economic or legal reasons related to a debtor’s financial condition, grants a concession to the debtor that it would not otherwise consider, unless it results in a delay in payment that is insignificant. These concessions typically include reductions in interest rate, extending the maturity of a loan, other modifications of payment terms, or a combination of modifications. When the Company modifies a loan, management evaluates for any possible impairment using either the discounted cash flows method, where the value of the modified loan is based on the present value of expected cash flows, discounted at the contractual interest rate of the original loan agreement, or by using the fair value of the collateral less selling costs if the loan is collateral-dependent. If management determines that the value of the modified loan is less than the recorded investment in the loan, impairment is recognized by segment or class of loan, as applicable, through an allowance estimate or charge-off to the allowance. This process is used, regardless of loan type, and for loans modified as TDRs that subsequently default on their modified terms. TDRs of $786 thousand and $153 thousand are included in the impaired loan numbers as of December 31, 2017 and December 31, 2016 , respectively. The increase was due to the addition of one loan, partially offset by the removal of one loan. There is $138 thousand in specific reserves on the performing TDR as of December 31, 2017 , compared to $34 thousand on the nonperforming TDR as of December 31, 2016 . At December 31, 2017 , the $786 thousand TDR is in accrual status since it continues to perform in accordance with its restructured terms. At December 31, 2016 , the $153 thousand TDR was in nonaccrual status. There was one loan modified as a TDR with a principal balance reduction during the year ended December 31, 2017 . To date, the Company’s TDRs consisted of interest rate reductions, interest only periods, and maturity extensions. There were no loans modified as a TDR within the previous 12 months that subsequently defaulted at some point during the years ended December 31, 2017 or 2016. In this case, the subsequent default is defined as 90 days past due or transferred to nonaccrual status. Other Loan Information Servicing Assets: Loans sold to others and serviced by the Company are not included in the accompanying Consolidated Balance Sheets. The total amount of such loans serviced, but owned by outside investors, amounted to approximately $132.1 million and $137.8 million at December 31, 2017 and 2016 , respectively. At December 31, 2017 and 2016 , the carrying value, which approximates fair value, of servicing assets was $1.8 million and $2.1 million , respectively, and is included in Other Assets. The fair value of SBA servicing assets was determined using a discount rate of 15% , constant prepayment speeds ranging from 15% to 18% , and interest strip multiples ranging from 2.08% to 3.80% , depending on each individual credit. The fair value of mortgage servicing assets was determined using a discount rate of 12% and the present value of excess servicing over 7 years . A summary of the changes in the related servicing assets for the past two years follows: For the years ended December 31, (In thousands) 2017 2016 Balance, beginning of year $ 2,086 $ 1,389 Servicing assets capitalized 172 1,472 Amortization of expense (458 ) (775 ) Provision for loss in fair value — — Balance, end of year $ 1,800 $ 2,086 In addition, the Company had a $1.4 million and $1.3 million discount related to the retained portion of the unsold SBA loans at December 31, 2017 and 2016 , respectively. Officer and Director Loans: In the ordinary course of business, the Company may extend credit to officers, directors or their associates. These loans are subject to the Company’s normal lending policy. An analysis of such loans, all of which are current as to principal and interest payments, is as follows: (In thousands) December 31, 2017 December 31, 2016 Balance, beginning of year $ 29,256 $ 37,394 New loans and advances 6,121 31 Loan repayments (2,268 ) (8,169 ) Balance, end of year $ 33,109 $ 29,256 Loan Portfolio Collateral: The majority of the Company’s loans are secured by real estate. Declines in the market values of real estate in the Company’s trade area impact the value of the collateral securing its loans. This could lead to greater losses in the event of defaults on loans secured by real estate. At December 31, 2017 approximately 94% of the Company’s loan portfolio was secured by real estate, compared to 96% at December 31, 2016 .

Allowance for Loan Losses and R

Allowance for Loan Losses and Reserve for Unfunded Loan Commitments	12 Months Ended
	Dec. 31, 2017
Financing Receivable, Allowance for Credit Loss, Additional Information [Abstract]
Allowance for Loan Losses and Reserve for Unfunded Loan Commitments	Allowance for Loan Losses and Reserve for Unfunded Loan Commitments Allowance for Loan Losses The Company has an established methodology to determine the adequacy of the allowance for loan losses that assesses the risks and losses inherent in the loan portfolio. At a minimum, the adequacy of the allowance for loan losses is reviewed by management on a quarterly basis. For purposes of determining the allowance for loan losses, the Company has segmented the loans in its portfolio by loan type. Loans are segmented into the following pools: SBA 7(a), SBA 504, commercial, residential mortgages, and consumer loans. Certain portfolio segments are further broken down into classes based on the associated risks within those segments and the type of collateral underlying each loan. Commercial loans are divided into the following three classes: commercial real estate, commercial real estate construction and commercial other. Consumer loans are divided into two classes as follows: home equity and other. The standardized methodology used to assess the adequacy of the allowance includes the allocation of specific and general reserves. The same standard methodology is used, regardless of loan type. Specific reserves are made to individual impaired loans and troubled debt restructurings (see Note 1 for additional information on this term). The general reserve is set based upon a representative average historical net charge-off rate adjusted for the following environmental factors: delinquency and impairment trends, charge-off and recovery trends, changes in the volume of restructured loans, volume and loan term trends, changes in risk and underwriting policy trends, staffing and experience changes, national and local economic trends, industry conditions and credit concentration changes. Within the five-year historical net charge-off rate, the Company weights the past three years more because it believes they are more indicative of future losses. All of the environmental factors are ranked and assigned a basis points value based on the following scale: low, low moderate, moderate, high moderate and high risk. Each environmental factor is evaluated separately for each class of loans and risk weighted based on its individual characteristics. • For SBA 7(a), SBA 504 and commercial loans, the estimate of loss based on pools of loans with similar characteristics is made through the use of a standardized loan grading system that is applied on an individual loan level and updated on a continuous basis. The loan grading system incorporates reviews of the financial performance of the borrower, including cash flow, debt-service coverage ratio, earnings power, debt level and equity position, in conjunction with an assessment of the borrower's industry and future prospects. It also incorporates analysis of the type of collateral and the relative loan to value ratio. • For residential mortgage and consumer loans, the estimate of loss is based on pools of loans with similar characteristics. Factors such as credit score, delinquency status and type of collateral are evaluated. Factors are updated frequently to capture the recent behavioral characteristics of the subject portfolios, as well as any changes in loss mitigation or credit origination strategies, and adjustments to the reserve factors are made as needed. According to the Company’s policy, a loss (“charge-off”) is to be recognized and charged to the allowance for loan losses as soon as a loan is recognized as uncollectable. All credits which are 90 days past due must be analyzed for the Company’s ability to collect on the credit. Once a loss is known to exist, the charge-off approval process is immediately expedited. This charge-off policy is followed for all loan types. The allocated allowance is the total of identified specific and general reserves by loan category. The allocation is not necessarily indicative of the categories in which future losses may occur. The total allowance is available to absorb losses from any segment of the portfolio. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses.

Reserve for Unfunded Loan Commitments In addition to the allowance for loan losses, the Company maintains a reserve for unfunded loan commitments at a level that management believes is adequate to absorb estimated probable losses. Adjustments to the reserve are made through other expense and applied to the reserve which is classified as other liabilities. At December 31, 2017 , a $ 292 thousand commitment reserve was reported on the balance sheet as an “other liability”, compared to a $ 181 thousand commitment reserve at December 31, 2016 , due to a larger loan portfolio requiring a larger general reserve. There were no losses on unfunded loan commitments during 2017 or 2016 .

FHLB borrowings at December 31, 2017 also consisted of five $10 million advances, and two $20 million advances. Comparatively, FHLB borrowings at December 31, 2016 consisted of six $10 million advances and two $20 million advances. The terms of these transactions at year end 2017 are as follows: • The $170.0 million FHLB overnight line of credit advance issued on December 29, 2017 was at a rate of 1.53% and was repaid on January 2, 2018. • The $10.0 million FHLB advance that was issued on December 7, 2017 has an adjustable interest rate equal to 3 month LIBOR plus 14.5 basis points and matures on June 7, 2018. This borrowing was swapped to a 5 year fixed rate borrowing at 1.730% . • The $10.0 million FHLB advance that was issued on August 16, 2017 has an adjustable interest rate equal to 3 month LIBOR plus 7.0 basis points and matures on February 16, 2018. This borrowing was swapped to a 5 year fixed rate borrowing at 1.103% . • The $20.0 million FHLB advance that was issued on July 5, 2017 has an adjustable interest rate equal to LIBOR plus 11.0 basis points and matures on January 5, 2018. This borrowing was swapped to a 5 year fixed rate borrowing at 1.048% . • The $10.0 million FHLB advance that was issued on July 7, 2016 has a fixed rate of 1.80% and matures on July 7, 2021 . • The $10.0 million FHLB advance that was issued on March 23, 2016 has a fixed rate of 2.10% and matures on December 23, 2020 . • The $10.0 million FHLB advance that was issued on October 27, 2015 has a fixed rate of 2.02% and matures on October 27, 2020. • The $10.0 million FHLB advance that was modified on October 27, 2015 has a fixed rate of 2.15% and matures on October 27, 2020. Repurchase Agreements At December 31, 2017 and 2016 , the Company was a party to a $15.0 million repurchase agreement that was entered into in February 2008, has a term of 10 years expiring on February 28, 2018 , and a rate of 3.67% . The borrowing was callable by the issuer on the repurchase date of May 29, 2008 and quarterly thereafter. Due to the call provisions of this advance, the expected maturity could differ from the contractual maturity. Subordinated Debentures At December 31, 2017 and 2016 , the Company was a party in the following subordinated debenture transactions: • On July 24, 2006, Unity (NJ) Statutory Trust II, a statutory business trust and wholly-owned subsidiary of Unity Bancorp, Inc., issued $10.0 million of floating rate capital trust pass through securities to investors due on July 24, 2036 . The subordinated debentures are redeemable in whole or part, prior to maturity but after July 24, 2011. The floating interest rate on the subordinated debentures is the three-month LIBOR plus 159 basis points and reprices quarterly. The floating interest rate was 3.26% at December 31, 2017 and 2.59% at December 31, 2016 . This has been swapped to a 3 year fixed rate borrowing at 0.885% . • On December 19, 2006, Unity (NJ) Statutory Trust III, a statutory business trust and wholly-owned subsidiary of Unity Bancorp, Inc., issued $5.0 million of floating rate capital trust pass through securities to investors due on December 19, 2036 . On February 26, 2016, Unity (NJ) Statutory Trust III, repurchased the $ 5.0 million of floating rate securities, and redeemed $155 thousand of the related common equity securities described below. The subordinated debentures were repurchased at a price of $0.5475 per dollar, which resulted in a gain of $2.3 million . • In connection with the formation of the statutory business trusts, the trusts also issued $465 thousand of common equity securities to the Company, which together with the proceeds stated above were used to purchase the subordinated debentures, under the same terms and conditions. At December 31, 2017 and 2016, $310 thousand of the common equity securities remained. The capital securities in each of the above transactions have preference over the common securities with respect to liquidation and other distributions and qualify as Tier I capital. Under the terms of the Dodd-Frank Wall Street Reform and Consumer Protection Act, these securities will continue to qualify as Tier 1 capital as the Company has less than $10 billion in assets. In accordance with FASB ASC Topic 810, “Consolidation,” the Company does not consolidate the accounts and related activity of Unity (NJ) Statutory Trust II and Unity (NJ) Statutory Trust III because it is not the primary beneficiary. The additional capital from each of these transactions was used to bolster the Company’s capital ratios and for general corporate purposes, including among other things, capital contributions to the Bank. The Company has the ability to defer interest payments on the subordinated debentures for up to 5 years without being in default. Due to the redemption provisions of these securities, the expected maturity could differ from the contractual maturity. Derivative Financial Instruments and Hedging Activities Derivative Financial Instruments The Company has a stand alone derivative financial instrument in the form of an interest rate swap agreement, which derives its value from underlying interest rates. This transaction involves both credit and market risk. The notional amounts are amounts on which calculations, payments, and the value of the derivative is based. Notional amounts do not represent direct credit exposures. Direct credit exposure is limited to the net difference between the calculated amounts to be received and paid, if any. Such difference, which represents the fair value of the derivative instrument, is reflected on the Company’s balance sheet as other assets or other liabilities. The Company is exposed to credit-related losses in the event of nonperformance by the counterparties to this agreement. The Company controls the credit risk of its financial contracts through credit approvals, limits and monitoring procedures, and does not expect any counterparties to fail their obligations. The Company deals only with primary dealers. Derivative instruments are generally either negotiated OTC contracts or standardized contracts executed on a recognized exchange. Negotiated OTC derivative contracts are generally entered into between two counterparties that negotiate specific agreement terms, including the underlying instrument, amount, exercise prices and maturity. Risk Management Policies – Hedging Instruments The primary focus of the Company’s asset/liability management program is to monitor the sensitivity of the Company’s net portfolio value and net income under varying interest rate scenarios to take steps to control its risks. On a quarterly basis, the Company evaluates the effectiveness of entering into any derivative agreement by measuring the cost of such an agreement in relation to the reduction in net portfolio value and net income volatility within an assumed range of interest rates. Interest Rate Risk Management – Cash Flow Hedging Instruments The Company has FHLB Adjustable Rate Credit (“ARC”) variable rate debt as a source of funds for use in the Company’s lending and investment activities and for other general business purposes. These debt obligations expose the Company to variability in interest payments due to changes in interest rates. If interest rates increase, interest expense increases. Conversely, if interest rates decrease, interest expense decreases. Management believes it is prudent to limit the variability of a portion of its interest payments and, therefore hedges its variable-rate interest payments. To meet this objective, management enters into interest rate swap agreements whereby the Company receives variable interest rate payments and makes fixed interest rate payments during the contract period. During the twelve months ended December 31, 2017 and 2016 , the Company received variable rate Libor payments from and paid fixed rates in accordance with its interest rate swap agreements. A summary of the Company’s outstanding interest rate swap agreements used to hedge variable rate debt at December 31, 2017 and 2016 , respectively is as follows: (In thousands, except %ages and years) 2017 2016 Notional amount $ 60,000 $ 60,000 Weighted average pay rate 1.26 % 1.43 % Weighted average receive rate 1.03 % 0.67 % Weighted average maturity in years 3.36 4.24 Unrealized gains relating to interest rate swaps $ 1,407 $ 1,204 At December 31, 2017 and 2016, the unrealized gains relating to interest rate swaps were recorded as an other asset. Changes in the fair value of interest rate swaps designated as hedging instruments of the variability of cash flows associated with long-term debt are reported in other comprehensive income.

Income Taxes	Income Taxes On December 22, 2017 the “Tax Cuts and Jobs Act” (TCJA) was signed into law, lowering the corporate tax rate from 35% to 21%, which will provide a significant tax benefit in 2018 and beyond. However, net income for 2017 was adversely impacted. Under ASC 740, Income Taxes , Unity was required to adjust its deferred income tax balances as of the enactment date to reflect a rate of 21%. This adjustment resulted in a $1.7 million increase in income tax expense and is included in the line "Federal - deferred provision" in the table below. The components of the provision for income taxes for the past two years are as follows: For the years ended December 31, (In thousands) 2017 2016 Federal - current provision $ 7,003 $ 6,352 Federal - deferred provision 1,702 73 Total federal provision 8,705 6,425 State - current provision 991 795 State - deferred (benefit) provision (156 ) 37 Total state provision 835 832 Total provision for income taxes $ 9,540 $ 7,257 Reconciliation between the reported income tax provision and the amount computed by multiplying income before taxes by the statutory Federal income tax rate for the past two years is as follows: For the years ended December 31, (In thousands, except percentages) 2017 2016 Federal income tax provision at statutory rate $ 7,852 $ 7,162 Increases (Decreases) resulting from: Stock option and restricted stock (428 ) — Bank owned life insurance (164 ) (132 ) Tax-exempt interest (56 ) (71 ) Meals and entertainment 22 21 Captive insurance premium (295 ) — State income taxes, net of federal income tax effect 543 541 Impact of rate change on deferred tax assets 1,733 — Other, net 333 (264 ) Provision for income taxes $ 9,540 $ 7,257 Effective tax rate 42.5 % 35.5 % Deferred income taxes are provided for temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities.

Deferred income taxes are recognized for tax consequences of “temporary differences” by applying enacted statutory tax rates to differences between the financial reporting and the tax basis of existing assets and liabilities. A deferred tax liability is recognized for all temporary differences that will result in future taxable income. A deferred tax asset is recognized for all temporary differences that will result in future tax deductions subject to reduction of the asset by a valuation allowance. The Company had a $296 thousand and $123 thousand valuation allowance for deferred tax assets related to its state net operating loss carry-forward deferred tax asset at December 31, 2017 and 2016 , respectively. The Company’s state net operating loss carry-forwards totaled approximately $4.2 million at December 31, 2017 and expire between 2030 and 2036. Included as a component of deferred tax assets is an income tax expense (benefit) related to unrealized gains (losses) on securities available for sale, a supplemental retirement plan (SERP) and interest rate swaps. The after-tax component of each of these is included in other comprehensive income (loss) in shareholders’ equity. The after-tax component related to securities available for sale was an unrealized loss of $335 thousand and $161 thousand for 2017 and 2016 , respectively. The after-tax component related to the SERP was an unrealized loss of $341 thousand for 2017 , compared to $391 thousand in 2016 . The after-tax component related to the interest rate swaps was an unrealized gain of $882 thousand for 2017 , compared to an unrealized gain of $712 thousand in the prior year. The Company follows FASB ASC Topic 740, “Income Taxes,” which prescribes a threshold for the financial statement recognition of income taxes and provides criteria for the measurement of tax positions taken or expected to be taken in a tax return. ASC 740 also includes guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition of income taxes. The Company did not recognize or accrue any interest or penalties related to income taxes during the years ended December 31, 2017 and 2016 . The Company does not have an accrual for uncertain tax positions as of December 31, 2017 or 2016 , as deductions taken and benefits accrued are based on widely understood administrative practices and procedures and are based on clear and unambiguous tax law. Tax returns for all years 2013 and thereafter are subject to future examination by tax authorities.

Regulatory Capital Requirements [Abstract]
Regulatory Capital	Regulatory Capital A significant measure of the strength of a financial institution is its capital base. Federal regulators have classified and defined capital into the following components: (1) tier 1 capital, which includes tangible shareholders’ equity for common stock, qualifying preferred stock and certain qualifying hybrid instruments, and (2) tier 2 capital, which includes a portion of the allowance for loan losses, subject to limitations, certain qualifying long-term debt, preferred stock and hybrid instruments, which do not qualify for tier 1 capital. The Parent Company and its subsidiary Bank are subject to various regulatory capital requirements administered by banking regulators. Quantitative measures of capital adequacy include the leverage ratio (tier 1 capital as a percentage of tangible assets), tier 1 risk-based capital ratio (tier 1 capital as a percent of risk-weighted assets), total risk-based capital ratio (total risk-based capital as a percent of total risk-weighted assets), and common equity tier 1 capital ratio. Minimum capital levels are regulated by risk-based capital adequacy guidelines, which require the Company and the Bank to maintain certain capital as a percentage of assets and certain off-balance sheet items adjusted for predefined credit risk factors (risk-weighted assets). Failure to meet minimum capital requirements can initiate certain mandatory and possibly discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action applicable to banks, the Company and the Bank must meet specific capital guidelines. Prompt corrective action provisions are not applicable to bank holding companies. In September 2010, the Group of Governors and Heads of Supervision, the oversight body of the Basel Committee on Banking Supervision, adopted Basel III, which constitutes a set of capital reform measures designed to strengthen the regulation, supervision and risk management of banking organizations worldwide. In order to implement Basel III and certain additional capital changes required by the Dodd-Frank Act, the FDIC approved, as an interim final rule in July 2013, the regulatory capital requirements substantially similar to final rules issued by the Board of Governors of the Federal Reserve System (“Federal Reserve”) for U.S. state nonmember banks and the Office of the Comptroller of the Currency for national banks. The interim final rule includes new risk-based capital and leverage ratios that will be phased-in from 2015 to 2019 for most state nonmember banks. The rule includes a new common equity Tier 1 capital (“CET1”) to risk-weighted assets ratio of 4.5% and a common equity Tier 1 capital conservation buffer of 2.5% of risk-weighted assets, which is in addition to the Tier 1 and Total risk-based capital requirements. The interim final rule also raises the minimum ratio of Tier 1 capital to risk-weighted assets from 4.0% to 6.0% and requires a minimum leverage ratio of 4.0%. The required minimum ratio of total capital to risk-weighted assets will remain 8.0%. The new risk-based capital requirements (except for the capital conservation buffer) became effective for the Company and the Bank on January 1, 2015. The new rules also include a one-time opportunity to opt-out of the changes to treatment of accumulated other comprehensive income (“AOCI”) components. By making the election to opt-out, the institution may continue treating AOCI items in a manner consistent with risk-based capital rules in place prior to January 2015. The Bank and the Company have made the election to opt out of the treatment of AOCI on the appropriate March 31, 2015 filings. The following table summarizes the Company's and the Bank's regulatory capital ratios at December 31, 2017 and December 31, 2016, as well as the minimum regulatory capital ratios required for the Bank to be deemed "well-capitalized".

Employee Benefit Plans	Employee Benefit Plans Stock Transactions On August 26, 2016, the Company declared a 10% stock dividend to shareholders' of record as of September 15, 2016. The 10% stock dividend was paid on September 30, 2016. All share amounts in the following tables have been restated to include the effect of the 10% stock dividend distribution. Stock Option Plans The Company has incentive and nonqualified option plans, which allow for the grant of options to officers, employees and members of the Board of Directors. Transactions under the Company’s stock option plans for 2017 and 2016 are summarized in the following table: Shares Weighted average exercise price Weighted average remaining contractual life in years Aggregate intrinsic value Outstanding at December 31, 2015 522,338 $ 6.45 5.1 $ 2,561,095 Options granted 127,400 11.11 Options exercised (90,871 ) 7.97 Options forfeited (1,833 ) 7.00 Options expired (4,275 ) 7.64 Outstanding at December 31, 2016 552,759 $ 7.26 5.7 $ 4,663,432 Options granted 47,100 16.37 Options exercised (94,679 ) 6.19 Options forfeited — — Options expired (607 ) 11.48 Outstanding at December 31, 2017 504,573 $ 8.31 5.7 $ 5,772,843 Exercisable at December 31, 2017 351,648 $ 6.53 4.6 $ 4,648,981 Grants under the Company’s incentive and nonqualified option plans generally vest over 3 years and must be exercised within 10 years of the date of grant. The exercise price of each option is the market price on the date of grant. As of December 31, 2017 , 2,462,585 shares have been reserved for issuance upon the exercise of options, 504,573 option grants are outstanding, and 1,575,640 option grants have been exercised, forfeited or expired, leaving 382,372 shares available for grant. The fair values of the options granted during 2017 and 2016 were estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions: For the years ended December 31, 2017 2016 Number of options granted 47,100 127,400 Weighted average exercise price $ 16.37 $ 11.11 Weighted average fair value of options $ 4.64 $ 3.49 Expected life in years (1) 6.57 6.79 Expected volatility (2) 28.12 % 31.02 % Risk-free interest rate (3) 2.18 % 1.94 % Dividend yield (4) 1.15 % 1.38 % (1) The expected life of the options was estimated based on historical employee behavior and represents the period of time that options granted are expected to be outstanding. (2) The expected volatility of the Company’s stock price was based on the historical volatility over the period commensurate with the expected life of the options. (3) The risk-free interest rate is the U.S Treasury rate commensurate with the expected life of the options on the date of grant. (4) The expected dividend yield is the projected annual yield based on the grant date stock price. Upon exercise, the Company issues shares from its authorized but unissued common stock to satisfy the options. The following table presents information about options exercised during 2017 and 2016 : For the years ended December 31, 2017 2016 Number of options exercised 94,679 90,871 Total intrinsic value of options exercised $ 1,073,474 $ 451,288 Cash received from options exercised 509,047 549,918 Tax deduction realized from options exercised 438,514 184,351 The following table summarizes information about stock options outstanding and exercisable at December 31, 2017 : Options outstanding Options exercisable Range of exercise prices Options outstanding Weighted average remaining contractual life (in years) Weighted average exercise price Options exercisable Weighted average exercise price 0.00 - 4.00 77,000 1.1 $ 3.51 77,000 $ 3.51 4.01 - 8.00 186,340 4.5 6.20 186,340 6.20 8.01 - 12.00 164,633 7.8 9.51 78,471 9.27 12.01 - 16.00 46,600 9.0 15.00 9,837 14.60 16.01 - 20.00 30,000 9.2 $ 16.75 — $ — Total 504,573 5.7 $ 8.31 351,648 $ 6.53 FASB ASC Topic 718, “Compensation - Stock Compensation,” requires an entity to recognize the fair value of equity awards as compensation expense over the period during which an employee is required to provide service in exchange for such an award (vesting period). Compensation expense related to stock options and the related income tax benefit for the years ended December 31, 2017 and 2016 are detailed in the following table: For the years ended December 31, 2017 2016 Compensation expense $ 283,823 $ 218,013 Income tax benefit 115,942 89,058 As of December 31, 2017 , unrecognized compensation costs related to nonvested share-based compensation arrangements granted under the Company’s stock option plans totaled approximately $357 thousand . That cost is expected to be recognized over a weighted average period of 1.7 years. Restricted Stock Awards Restricted stock is issued under the stock bonus program to reward employees and directors and to retain them by distributing stock over a period of time. The following table summarizes nonvested restricted stock activity for the year ended December 31, 2017 : Shares Average grant date fair value Nonvested restricted stock at December 31, 2016 97,203 $ 9.47 Granted 38,400 16.36 Canceled — — Vested (41,600 ) 8.92 Nonvested restricted stock at December 31, 2017 94,003 $ 12.53 Restricted stock awards granted to date vest over a period of 4 years and are recognized as compensation to the recipient over the vesting period. Unless the recipient makes an election to recognize all compensation on the grant date, the awards are recorded at fair market value at the time of grant and amortized into salary expense on a straight line basis over the vesting period. As of December 31, 2017 , 518,157 shares of restricted stock were reserved for issuance, of which 111,404 shares are available for grant. Restricted stock awards granted during the years ended December 31, 2017 and 2016 were as follows: For the years ended December 31, 2017 2016 Number of shares granted 38,400 44,016 Average grant date fair value $ 16.36 $ 11.21 Compensation expense related to the restricted stock for the years ended December 31, 2017 and 2016 is detailed in the following table: For the years ended December 31, 2017 2016 Compensation expense $ 462,470 $ 327,151 Income tax benefit 188,919 133,644 As of December 31, 2017 , there was approximately $850 thousand of unrecognized compensation cost related to nonvested restricted stock awards granted under the Company’s stock incentive plans. That cost is expected to be recognized over a weighted average period of 2.6 years. 401(k) Savings Plan The Bank has a 401(k) savings plan covering substantially all employees. Under the Plan, an employee can contribute up to 80 percent of their salary on a tax deferred basis. The Bank may also make discretionary contributions to the Plan. The Bank contributed $492 thousand and $388 thousand to the Plan in 2017 and 2016 , respectively. Deferred Fee Plan The Company has a deferred fee plan for Directors and executive management. Directors of the Company have the option to elect to defer up to 100 percent of their respective retainer and Board of Director fees, and each member of executive management has the option to elect to defer 100 percent of their year end cash bonuses. Director and executive deferred fees totaled $149 thousand in 2017 and $120 thousand in 2016 , and the interest paid on deferred balances totaled $44 thousand in 2017 and $34 thousand in 2016 . The fees distributed on the deferred balances totaled $8 thousand in 2017 . No fees were distributed in 2016 . Benefit Plans In addition to the 401(k) savings plan which covers substantially all employees in 2015, the Company established an unfunded supplemental defined benefit plan to provide additional retirement benefits for the President and Chief Executive Officer (“CEO”) and certain key executives. On June 4, 2015, the Company approved the Supplemental Executive Retirement Plan (“SERP”) pursuant to which the President and CEO is entitled to receive certain supplemental nonqualified retirement benefits. On November 21, 2016 the Company approved a change in calculation of the Retirement Benefit payable under the Plan so that the Retirement Benefit shall be an amount equal to forty ( 40% ) percent of the average of the Executive's base salary for the thirty-six ( 36 ) months immediately preceding executive's separation from service after age 66, adjusted annually thereafter by 2 percent . The total benefit is to be made payable in fifteen annual installments. The future payments are estimated to total $3.4 million . A discount rate of 4.00 percent was used to calculate the present value of the benefit obligation. The President and CEO commenced vesting to this retirement benefit on January 1, 2014, and it will vest an additional 3 percent each year until fully vested on January 1, 2024. In the event that the President and CEO’s separation from service from the company were to occur prior to full vesting, the President and CEO would be entitled to and shall be paid the vested portion of the retirement benefit calculated as of the date of separation from service. Notwithstanding the foregoing, upon a Change in Control, and provided that within 6 months following the Change in Control the President and CEO is involuntarily terminated for reasons other than “cause” or the President and CEO resigns for “good reason”, as such is defined in the SERP, or the President and CEO voluntarily terminates his employment after being offered continued employment in a position that is not a “Comparable Position”, as such is also defined in the SERP, the President and CEO shall become 100 percent vested in the full retirement benefit. No contributions or payments have been made for the year 2017 or 2016 . The following table summarizes the components of the net periodic pension cost of the defined benefit plan recognized during the years ended December 31, 2017 and 2016 : For the years ended December 31, (In thousands) 2017 2016 Service cost $ 121 $ 62 Interest cost 43 38 Amortization of prior service cost 83 83 Net periodic benefit cost $ 247 $ 183 The following table summarizes the changes in benefit obligations of the defined benefit plan recognized during the years ended December 31, 2017 : For the years ended December 31, (In thousands) 2017 2016 Benefit obligation, beginning of year $ 1,023 $ 923 Service cost 121 62 Interest cost 43 38 Benefit obligation, end of year $ 1,187 $ 1,023 On October 22, 2015, the Company entered into an Executive Incentive Retirement Plan (the “Plan”) with key executive officers. The Plan has an effective date of January 1, 2015. The Plan is an unfunded, nonqualified deferred compensation plan. For any Plan Year, a guaranteed annual Deferral Award percentage of seven and one half percent ( 7.5% ) of the participant’s annual base salary shall be credited to each Participant’s Deferred Benefit Account. A discretionary annual Deferral Award equal to seven and one half percent ( 7.5% ) of the participant’s annual base salary may be credited to the Participant’s account in addition to the guaranteed Deferral Award, if the Bank exceeds the benchmarks set forth in the Annual Executive Bonus Matrix. The total Deferral Award shall never exceed fifteen percent ( 15% ) of the participant's base salary for any given Plan Year. Each Participant shall be one hundred percent ( 100% ) vested in all Deferral Awards as of the date they are awarded. As of December 31, 2017 , the company had total expenses of $ 90 thousand , compared to $ 30 thousand for the prior year. The Plan is reflected on the Company’s balance sheet as accrued expenses. Certain members of management are also enrolled in a split-dollar life insurance plan with a post retirement death benefit of $250 thousand . Total expenses related to this plan were $5 thousand in 2017 and 2016 , respectively.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Fair Value Measurement The Company follows FASB ASC Topic 820, “Fair Value Measurement and Disclosures,” which requires additional disclosures about the Company’s assets and liabilities that are measured at fair value. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. In determining fair value, the Company uses various methods including market, income and cost approaches. Based on these approaches, the Company often utilizes certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and/or the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated, or generally unobservable inputs. The Company utilizes techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed as follows: Level 1 Inputs • Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. • Generally, this includes debt and equity securities and derivative contracts that are traded in an active exchange market (i.e. New York Stock Exchange), as well as certain U.S. Treasury, U.S. Government and sponsored entity agency mortgage-backed securities that are highly liquid and are actively traded in over-the-counter markets. Level 2 Inputs • Quoted prices for similar assets or liabilities in active markets. • Quoted prices for identical or similar assets or liabilities in inactive markets. • Inputs other than quoted prices that are observable, either directly or indirectly, for the term of the asset or liability (i.e., interest rates, yield curves, credit risks, prepayment speeds or volatilities) or “market corroborated inputs.” • Generally, this includes U.S. Government and sponsored entity mortgage-backed securities, corporate debt securities and derivative contracts. Level 3 Inputs • Prices or valuation techniques that require inputs that are both unobservable (i.e. supported by little or no market activity) and that are significant to the fair value of the assets or liabilities. • These assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Fair Value on a Recurring Basis The following is a description of the valuation methodologies used for instruments measured at fair value on a recurring basis: Securities Available for Sale As of December 31, 2017 , the fair value of the Company's AFS securities portfolio was $53.5 million . Approximately 60 percent of the portfolio was made up of residential mortgage-backed securities, which had a fair value of $31.9 million at December 31, 2017 . Approximately $31.3 million of the residential mortgage-backed securities are guaranteed by the Government National Mortgage Association ("GNMA"), the Federal National Mortgage Association ("FNMA") or the Federal Home Loan Mortgage Corporation ("FHLMC"). The underlying loans for these securities are residential mortgages that are geographically dispersed throughout the United States. All of the Company’s AFS securities were classified as Level 2 assets at December 31, 2017 . The valuation of AFS securities using Level 2 inputs was primarily determined using the market approach, which uses quoted prices for similar assets or liabilities in active markets and all other relevant information. It includes model pricing, defined as valuing securities based upon their relationship with other benchmark securities. Derivative Assets and Liabilities The Company's derivative assets and liabilities consist of transactions as part of management's strategy to manage interest rate risk. The valuation of the Company's interest rate swaps is obtained from a third-party pricing service and is determined using a discounted cash flow analysis on the expected cash flows of each derivative. The pricing analysis is based on observable inputs for the contractual terms of the derivatives, including the period to maturity and interest rate curves. The Company has determined that the majority of the inputs used to value its interest rate derivatives fall within Level 2 of the fair value hierarchy. There were no changes in the inputs or methodologies used to determine fair value during the year ended December 31, 2017 , as compared to the year ended December 31, 2016 . The tables below present the balances of assets measured at fair value on a recurring basis as of December 31 st for the past two years: Fair Value Measurements at December 31, 2017 Using (In thousands) Assets/Liabilities Measured at Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Measured on a recurring basis: Assets: Securities available for sale: U.S. Government sponsored entities $ 5,691 $ — $ 5,691 $ — State and political subdivisions 5,192 — 5,192 — Residential mortgage-backed securities 31,878 — 31,878 — Corporate and other securities 10,732 — 10,732 — Total securities available for sale $ 53,493 $ — $ 53,493 $ — Interest rate swap agreements 1,407 — 1,407 — Total $ 1,407 $ — $ 1,407 $ — Fair Value Measurements at December 31, 2016 Using (In thousands) Assets/Liabilities Measured at Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Measured on a recurring basis: Assets: Securities available for sale: U.S. Government sponsored entities $ 3,716 $ — $ 3,716 $ — State and political subdivisions 5,502 — 5,502 — Residential mortgage-backed securities 21,631 — 21,631 — Corporate and other securities 9,719 — 9,719 — Total securities available for sale $ 40,568 $ — $ 40,568 $ — Interest rate swap agreements 1,204 — 1,204 — Total $ 1,204 $ — $ 1,204 $ — Fair Value on a Nonrecurring Basis Certain assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The following is a description of the valuation methodologies used for instruments measured at fair value on a nonrecurring basis: Appraisal Policy All appraisals must be performed in accordance with the Uniform Standards of Professional Appraisal Practice (“USPAP”). Appraisals are certified to the Company and performed by appraisers on the Company’s approved list of appraisers. Evaluations are completed by a person independent of Company management. The content of the appraisal depends on the complexity of the property. Appraisals are completed on a “retail value” and an “as is value”. The Company requires current real estate appraisals on all loans that become OREO or in-substance foreclosure, loans that are classified substandard, doubtful or loss, or loans that are over $100,000 and nonperforming. Prior to each balance sheet date, the Company values impaired collateral-dependent loans and OREO based upon a third party appraisal, broker's price opinion, drive by appraisal, automated valuation model, updated market evaluation, or a combination of these methods. The amount is discounted for the decline in market real estate values (for original appraisals), for any known damage or repair costs, and for selling and closing costs. The amount of the discount ranges from 10 to 15 percent and is dependent upon the method used to determine the original value. The original appraisal is generally used when a loan is first determined to be impaired. When applying the discount, the Company takes into consideration when the appraisal was performed, the collateral’s location, the type of collateral, any known damage to the property and the type of business. Subsequent to entering impaired status and the Company determining that there is a collateral shortfall, the Company will generally, depending on the type of collateral, order a third party appraisal, broker's price opinion, automated valuation model or updated market evaluation. Subsequent to receiving the third party results, the Company will discount the value 6% to 10% percent for selling and closing costs. OREO The fair value was determined using appraisals, which may be discounted based on management’s review and changes in market conditions (Level 3 Inputs). Impaired Collateral-Dependent Loans The Company's assets measured at fair value on a non-recurring basis are limited to impaired loans and other real estate owned. Impaired loans are classified within level 3 of the valuation hierarchy. The fair value of impaired collateral-dependent loans is derived in accordance with FASB ASC Topic 310, “Receivables.” Fair value is determined based on the loan’s observable market price or the fair value of the collateral, as determined through either an appraisal or evaluation process. The basis for the Company's appraisal and appraisal review process is based on regulatory guidelines and strives to comply with all regulatory appraisal laws, regulations and the Uniform Standard of Professional Appraisal Practice. All appraisals are "as is" (the property's highest and best use) valuations based on the net realizable value, which is the appraised value less any closing costs, when applicable. Partially charged-off loans are measured for impairment based upon an appraisal for collateral-dependent loans. When an updated appraisal is received for a nonperforming loan, the value on the appraisal is discounted in the manner discussed above. If there is a deficiency in the value after the Company applies these discounts, management applies a specific reserve and the loan remains in nonaccrual status. The receipt of an updated appraisal would not qualify as a reason to put a loan back into accruing status. The Company removes loans from nonaccrual status when the borrower makes six months of contractual payments and demonstrates the ability to service the debt going forward. Charge-offs are determined based upon the loss that management believes the Company will incur after evaluating collateral for impairment based upon the valuation methods described above and the ability of the borrower to pay any deficiency. Other real estate owned is comprised of real estate acquired by foreclosure and deeds in lieu of foreclosure. Other real estate owned is carried at the lower of the recorded investment in the property or its fair value less estimated costs to sell such property (as determined by independent appraisal) within level 3 of the fair value hierarchy. Prior to foreclosure, the value of the underlying loan is written down to the fair value of the real estate to be acquired by a charge to the allowance for loan losses, if necessary. The fair value is reviewed periodically and subsequent write downs are made accordingly through a charge to operations. The valuation allowance for impaired loans is included in the allowance for loan losses in the consolidated balance sheets. At December 31, 2017 , the valuation allowance for impaired loans was $332 thousand , an increase of $53 thousand from $280 thousand at December 31, 2016 . The following tables present the assets and liabilities subject to fair value adjustments (impairment) on a non-recurring basis carried on the balance sheet by caption and by level within the hierarchy (as described above): Fair Value Measurements at December 31, 2017 Using (In thousands) Assets/Liabilities Measured at Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Net Provision (Credit) During Period Measured on a non-recurring basis: Financial assets: OREO $ 426 $ — $ — $ 426 $ (299 ) Impaired collateral-dependent loans 1,126 — — 1,126 (86 ) Fair Value Measurements at December 31, 2016 Using (In thousands) Assets/Liabilities Measured at Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Net Provision (Credit) During Period Measured on a non-recurring basis: Financial assets: OREO $ 1,050 $ — $ — $ 1,050 $ (1,110 ) Impaired collateral-dependent loans 1,767 — — 1,767 (665 ) Fair Value of Financial Instruments FASB ASC Topic 825, “Financial Instruments,” requires the disclosure of the estimated fair value of certain financial instruments, including those financial instruments for which the Company did not elect the fair value option. These estimated fair values as of December 31, 2017 and December 31, 2016 have been determined using available market information and appropriate valuation methodologies. Considerable judgment is required to interpret market data to develop estimates of fair value. The estimates presented are not necessarily indicative of amounts the Company could realize in a current market exchange. The use of alternative market assumptions and estimation methodologies could have had a material effect on these estimates of fair value. The methodology for estimating the fair value of financial assets and liabilities that are measured on a recurring or nonrecurring basis are discussed above. The following methods and assumptions were used to estimate the fair value of other financial instruments for which it is practicable to estimate that value: Cash and Cash Equivalents For these short-term instruments, the carrying value is a reasonable estimate of fair value. Securities The fair value of securities is based upon quoted market prices for similar or identical assets or other observable inputs (Level 2) or externally developed models that use unobservable inputs due to limited or no market activity of the instrument (Level 3). SBA Loans Held for Sale The fair value of SBA loans held for sale is estimated by using a market approach that includes significant other observable inputs. Loans The fair value of loans is estimated by discounting the future cash flows using current market rates that reflect the interest rate risk inherent in the loan, except for previously discussed impaired loans. Federal Home Loan Bank Stock Federal Home Loan Bank stock is carried at cost. Carrying value approximates fair value based on the redemption provisions of the issues. Servicing Assets Servicing assets do not trade in an active, open market with readily observable prices. The Company estimates the fair value of servicing assets using discounted cash flow models incorporating numerous assumptions from the perspective of a market participant including market discount rates and prepayment speeds. The Company uses the carrying value of the servicing assets to approximate the fair value. Accrued Interest The carrying amounts of accrued interest approximate fair value. Deposit Liabilities The fair value of demand deposits and savings accounts is the amount payable on demand at the reporting date (i.e. carrying value). The fair value of fixed-maturity certificates of deposit is estimated by discounting the future cash flows using current market rates. Borrowed Funds and Subordinated Debentures The fair value of borrowings is estimated by discounting the projected future cash flows using current market rates. Standby Letters of Credit At December 31, 2017 , the Bank had standby letters of credit outstanding of $5.6 million , as compared to $4.1 million at December 31, 2016 . The fair value of these commitments is nominal. The table below presents the carrying amount and estimated fair values of the Company’s financial instruments not previously presented as of December 31 st for the past two years: December 31, 2017 December 31, 2016 (In thousands) Fair value level Carrying amount Estimated fair value Carrying amount Estimated fair value Financial assets: Cash and cash equivalents Level 1 $ 150,254 $ 150,254 $ 105,895 $ 105,895 Securities (1) Level 2 69,800 69,839 61,547 61,536 SBA loans held for sale Level 2 22,810 25,568 14,773 16,440 Loans, net of allowance for loan losses (2) Level 2 1,134,308 1,133,739 946,062 944,772 Federal Home Loan Bank stock Level 2 12,863 12,863 6,037 6,037 Servicing assets Level 3 1,800 1,800 2,086 2,086 Accrued interest receivable Level 2 5,447 5,447 4,462 4,462 OREO Level 3 426 426 1,050 1,050 Financial liabilities: Deposits Level 2 1,043,137 1,041,111 945,723 944,886 Borrowed funds and subordinated debentures Level 2 285,310 284,117 131,310 130,319 Accrued interest payable Level 2 436 436 430 430 (1) Includes held to maturity commercial mortgage-backed securities that are considered Level 3 at December 31, 2016.

Unity Risk Management, Inc. is the Company's captive insurance company that insures risks to the bank not insured by the traditional commercial insurance market.
Use Of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Amounts requiring the use of significant estimates include the allowance for loan losses, valuation of deferred tax and servicing assets, the carrying value of loans held for sale and other real estate owned, the valuation of securities and the determination of other-than-temporary impairment for securities and fair value disclosures. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks, federal funds sold and interest-bearing deposits.
Securities	Securities The Company classifies its securities into two categories, available for sale and held to maturity. Securities that are classified as available for sale are stated at fair value. Unrealized gains and losses on securities available for sale are generally excluded from results of operations and are reported as other comprehensive income, a separate component of shareholders’ equity, net of taxes. Securities classified as available for sale include securities that may be sold in response to changes in interest rates, changes in prepayment risks or for asset/liability management purposes. The cost of securities sold is determined on a specific identification basis. Gains and losses on sales of securities are recognized in the Consolidated Statements of Income on the date of sale. Securities are classified as held to maturity based on management’s intent and ability to hold them to maturity. Such securities are stated at cost, adjusted for unamortized purchase premiums and discounts using the level yield method. If transfers between the available for sale and held to maturity portfolios occur, they are accounted for at fair value and unrealized holding gains and losses are accounted for at the date of transfer. For securities transferred to available for sale from held to maturity, unrealized gains or losses as of the date of the transfer are recognized in other comprehensive income (loss), a separate component of shareholders’ equity. For securities transferred into the held to maturity portfolio from the available for sale portfolio, unrealized gains or losses as of the date of transfer continue to be reported in other comprehensive income (loss), and are amortized over the remaining life of the security as an adjustment to its yield, consistent with amortization of the premium or accretion of the discount. For additional information on securities, see Note 3 to the Consolidated Financial Statements. Other-Than-Temporary Impairment The Company has a process in place to identify debt securities that could potentially incur credit impairment that is other-than-temporary. This process involves monitoring late payments, pricing levels, downgrades by rating agencies, key financial ratios, financial statements, revenue forecasts and cash flow projections as indicators of credit issues. Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concern warrants such evaluation. This evaluation considers relevant facts and circumstances in evaluating whether a credit or interest rate-related impairment of a security is other-than-temporary. Relevant facts and circumstances considered include: (1) the extent and length of time the fair value has been below cost; (2) the reasons for the decline in value; (3) the financial position and access to capital of the issuer, including the current and future impact of any specific events and (4) for fixed maturity securities, the intent to sell a security or whether it is more likely than not the Company will be required to sell the security before the recovery of its amortized cost which, in some cases, may extend to maturity. For debt securities that are considered other-than-temporarily impaired where management has no intent to sell and the Company has no requirement to sell prior to recovery of its amortized cost basis, the amount of the impairment 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 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. For debt securities where management has the intent to sell, the amount of the impairment is reflected in earnings as realized losses. The present value of expected future cash flows is determined using the best estimate cash flows discounted at the effective interest rate implicit to the security at the date of purchase or the current yield to accrete an asset-backed or floating rate security. The methodology and assumptions for establishing the best estimate cash flows vary depending on the type of security. The asset-backed securities cash flow estimates are based on bond specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity and prepayment speeds and structural support, including subordination and guarantees. The corporate bond cash flow estimates are derived from scenario-based outcomes of expected corporate restructurings or the disposition of assets using bond specific facts and circumstances including timing, security interests and loss severity.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Loans	Loans Loans Held for Sale Loans held for sale represent the guaranteed portion of SBA loans and are reflected at the lower of aggregate cost or market value. The Company originates loans to customers under an SBA program that historically has provided for SBA guarantees of up to 90 percent of each loan. The Company generally sells the guaranteed portion of its SBA loans to a third party and retains the servicing, holding the nonguaranteed portion in its portfolio. The net amount of loan origination fees on loans sold is included in the carrying value and in the gain or loss on the sale. When sales of SBA loans do occur, the premium received on the sale and the present value of future cash flows of the servicing assets are recognized in income. All criteria for sale accounting must be met in order for the loan sales to occur; see details under the “Transfers of Financial Assets” heading above. Servicing assets represent the estimated fair value of retained servicing rights, net of servicing costs, at the time loans are sold. Servicing assets are amortized in proportion to, and over the period of, estimated net servicing revenues. Impairment is evaluated based on stratifying the underlying financial assets by date of origination and term. Fair value is determined using prices for similar assets with similar characteristics, when available, or based upon discounted cash flows using market-based assumptions. Any impairment, if temporary, would generally be reported as a valuation allowance. Serviced loans sold to others are not included in the accompanying Consolidated Balance Sheets. Income and fees collected for loan servicing are credited to noninterest income when earned, net of amortization on the related servicing assets. For additional information on servicing assets, see Note 4 to the Consolidated Financial Statements. Loans Held for Investment Loans held for investment are stated at the unpaid principal balance, net of unearned discounts and deferred loan origination fees and costs. In accordance with the level yield method, loan origination fees, net of direct loan origination costs, are deferred and recognized over the estimated life of the related loans as an adjustment to the loan yield. Interest is credited to operations primarily based upon the principal balance outstanding. Loans are reported as past due when either interest or principal is unpaid in the following circumstances: fixed payment loans when the borrower is in arrears for two or more monthly payments; open end credit for two or more billing cycles; and single payment notes if interest or principal remains unpaid for 30 days or more. Nonperforming loans consist of loans that are not accruing interest as a result of principal or interest being delinquent for a period of 90 days or more or when the ability to collect principal and interest according to the contractual terms is in doubt (nonaccrual loans). When a loan is classified as nonaccrual, interest accruals are discontinued and all past due interest previously recognized as income is reversed and charged against current period earnings. Generally, until the loan becomes current, any payments received from the borrower are applied to outstanding principal until such time as management determines that the financial condition of the borrower and other factors merit recognition of a portion of such payments as interest income. Loans may be returned to an accrual status when the ability to collect is reasonably assured and when the loan is brought current as to principal and interest. Loans are charged off when collection is sufficiently questionable and when the Company can no longer justify maintaining the loan as an asset on the balance sheet. Loans qualify for charge-off when, after thorough analysis, all possible sources of repayment are insufficient. These include: 1) potential future cash flows, 2) value of collateral, and/or 3) strength of co-makers and guarantors. All unsecured loans are charged off upon the establishment of the loan’s nonaccrual status. Additionally, all loans classified as a loss or that portion of the loan classified as a loss is charged off. All loan charge-offs are approved by the Board of Directors. Troubled debt restructurings ("TDRs") occur when a creditor, for economic or legal reasons related to a debtor’s financial condition, grants a concession to the debtor that it would not otherwise consider. These concessions typically include reductions in interest rate, extending the maturity of a loan, or a combination of both. Interest income on accruing TDRs is credited to operations primarily based upon the principal amount outstanding, as stated in the paragraphs above. The Company evaluates its loans for impairment. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. The Company has defined impaired loans to be all TDRs and nonperforming loans. Impairment is evaluated in total for smaller-balance loans of a similar nature (consumer and residential mortgage loans), and on an individual basis for all other loans. Impairment of a loan is measured based on the present value of expected future cash flows, discounted at the loan's effective interest rate, or as a practical expedient, based on a loan’s observable market price or the fair value of collateral, net of estimated costs to sell, if the loan is collateral-dependent. If the value of the impaired loan is less than the recorded investment in the loan, the Company establishes a valuation allowance, or adjusts existing valuation allowances, with a corresponding charge to the provision for loan losses. For additional information on loans, see Note 4 to the Consolidated Financial Statements.
Allowance for Loan Losses and Reserve for Unfunded Loan Commitments	Allowance for Loan Losses and Reserve for Unfunded Loan Commitments The allowance for loan losses is maintained at a level management considers adequate to provide for probable loan losses as of the balance sheet date. The allowance is increased by provisions charged to expense and is reduced by net charge-offs. The level of the allowance is based on management’s evaluation of probable losses in the loan portfolio, after consideration of prevailing economic conditions in the Company’s market area, the volume and composition of the loan portfolio, and historical loan loss experience. The allowance for loan losses consists of specific reserves for individually impaired credits and TDRs, reserves for nonimpaired loans based on historical loss factors adjusted for general economic factors and other qualitative risk factors such as changes in delinquency trends, industry concentrations or local/national economic trends. This risk assessment process is performed at least quarterly, and, as adjustments become necessary, they are realized in the periods in which they become known. Although management attempts to maintain the allowance at a level deemed adequate to provide for probable losses, future additions to the allowance may be necessary based upon certain factors including changes in market conditions and underlying collateral values. In addition, various regulatory agencies periodically review the adequacy of the Company’s allowance for loan losses. These agencies may require the Company to make additional provisions based on judgments about information available at the time of the examination. The Company maintains a reserve for unfunded loan commitments at a level that management believes is adequate to absorb estimated probable losses. Adjustments to the reserve are made through other expenses and applied to the reserve which is classified as other liabilities. For additional information on the allowance for loan losses and reserve for unfunded loan commitments, see Note 5 to the Consolidated Financial Statements.
Premises and Equipment	Premises and Equipment Land is carried at cost. All other fixed assets are carried at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The useful life of buildings is not to exceed 30 years ; furniture and fixtures is generally 10 years or less, and equipment is 3 to 5 years . Leasehold improvements are depreciated over the life of the underlying lease. For additional information on premises and equipment, see Note 6 to the Consolidated Financial Statements.
Bank Owned Life Insurance	Bank Owned Life Insurance The Company purchased life insurance policies on certain members of management. Bank owned life insurance is recorded at its cash surrender value or the amount that can be realized.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock Federal law requires a member institution of the Federal Home Loan Bank system to hold stock of its district FHLB according to a predetermined formula. The stock is carried at cost. Management reviews the stock for impairment based on the ultimate recoverability of the cost basis in the stock. The stock’s value is determined by the ultimate recoverability of the par value rather than by recognizing temporary declines. Management considers such criteria as the significance of the decline in net assets, if any, of the FHLB, the length of time this situation has persisted, commitments by the FHLB to make payments required by law or regulation, the impact of legislative and regulatory changes on the customer base of the FHLB and the liquidity position of the FHLB.
Other Real Estate Owned	Other Real Estate Owned Other real estate owned is recorded at the fair value, less estimated costs to sell at the date of acquisition, with a charge to the allowance for loan losses for any excess of the loan carrying value over such amount. Subsequently, OREO is carried at the lower of cost or fair value, as determined by current appraisals. Certain costs that increase the value or extend the useful life in preparing properties for sale are capitalized to the extent that the appraisal amount exceeds the carry value, and expenses of holding foreclosed properties are charged to operations as incurred. Appraisals The Company requires current real estate appraisals on all loans that become OREO or in-substance foreclosure, loans that are classified substandard, doubtful or loss, or loans that are over $ 100,000 and nonperforming. Prior to each balance sheet date, the Company values impaired collateral-dependent loans and OREO based upon a third party appraisal, broker's price opinion, drive by appraisal, automated valuation model, updated market evaluation, or a combination of these methods. The amount is discounted for the decline in market real estate values (for original appraisals), for any known damage or repair costs, and for selling and closing costs. The amount of the discount is dependent upon the method used to determine the original value. The original appraisal is generally used when a loan is first determined to be impaired. When applying the discount, the Company takes into consideration when the appraisal was performed, the collateral’s location, the type of collateral, any known damage to the property and the type of business. Subsequent to entering impaired status and the Company determining that there is a collateral shortfall, the Company will generally, depending on the type of collateral, order a third party appraisal, broker's price opinion, automated valuation model or updated market evaluation. Subsequent to receiving the third party results, the Company will discount the value 6 to 10 percent for selling and closing costs.
Income Taxes	Income Taxes The Company follows Financial Accounting Standards Board Accounting Standards Codification ("FASB ASC") Topic 740, “Income Taxes,” which prescribes a threshold for the financial statement recognition of income taxes and provides criteria for the measurement of tax positions taken or expected to be taken in a tax return. ASC 740 also includes guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition of income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the enacted tax rates applicable to taxable income for the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation reserves are established against certain deferred tax assets when it is more likely than not that the deferred tax assets will not be realized. Increases or decreases in the valuation reserve are charged or credited to the income tax provision. When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that ultimately would be sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. The evaluation of a tax position taken is considered by itself and not offset or aggregated with other positions. Tax positions that meet the more likely than not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. Interest and penalties associated with unrecognized tax benefits are recognized in income tax expense on the income statement. For additional information on income taxes, see Note 15 to the Consolidated Financial Statements.
Net Income Per Share	Net Income Per Share Basic net income per common share is calculated as net income available to common shareholders divided by the weighted average common shares outstanding during the reporting period. Diluted net income per common share is computed similarly to that of basic net income per common share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if all potentially dilutive common shares, principally stock options, were issued during the reporting period utilizing the Treasury stock method.
