As of June 30, 2016 , there were 25 securities with unrealized losses held in the Company's portfolio. These securities were temporarily impaired as a result of changes in interest rates reducing their fair value, of which 13 had been temporarily impaired for 12 months or more. At the present time, there have been no material changes in the credit quality of these securities resulting in other than temporary impairment, and in Management's opinion, no additional write-down for other-than-temporary impairment is warranted.

The net unrealized loss, net of taxes, on these securities at the date of the transfer was $15,000 . The net unrealized holding loss at the time of transfer continues to be reported in accumulated other comprehensive income (loss), net of tax and is amortized over the remaining lives of the securities as an adjustment of the yield. The amortization of the net unrealized loss reported in accumulated other comprehensive income (loss) will offset the effect on interest income of the discount for the transferred securities. The remaining unamortized balance of the net unrealized losses for the securities transferred from available for sale to held to maturity was $133,000 at June 30, 2016 . These securities were transferred as a part of the Company's overall investment and balance sheet strategies. The Bank is a member of the Federal Home Loan Bank ("FHLB") of Boston, a cooperatively owned wholesale bank for housing and finance in the six New England States. As a requirement of membership in the FHLB, the Bank must own a minimum required amount of FHLB stock, calculated periodically based primarily on its level of borrowings from the FHLB. The Bank uses the FHLB for much of its wholesale funding needs. As of June 30, 2016 and 2015 , and December 31, 2015 , the Bank's investment in FHLB stock totaled $13,404,000 , $12,875,000 and $13,220,000 , respectively. FHLB stock is a non-marketable equity security and therefore is reported at cost, which equals par value. The Company periodically evaluates its investment in FHLB stock for impairment based on, among other factors, the capital adequacy of the FHLB and its overall financial condition. No impairment losses have been recorded through June 30, 2016 . The Bank will continue to monitor its investment in FHLB stock.

A loan is "well secured" if it is secured (1) by collateral in the form of liens on or pledges of real or personal property, including securities, that have a realizable value sufficient to discharge the debt (including accrued interest) in full, or (2) by the guarantee of a financially responsible party. A loan is "in the process of collection" if collection of the loan is proceeding in due course either (1) through legal action, including judgment enforcement procedures, or, (2) in appropriate circumstances, through collection efforts not involving legal action which are reasonably expected to result in repayment of the debt or in its restoration to a current status in the near future. Cash payments received on non-accrual loans, which are included in impaired loans, are applied to reduce the loan's principal balance until the remaining principal balance is deemed collectible, after which interest is recognized when collected. As a general rule, a loan may be restored to accrual status when payments are current for a substantial period of time, generally six months, and repayment of the remaining contractual amounts is expected or when it otherwise becomes well secured and in the process of collection. Information on nonaccrual loans as of June 30, 2016 and 2015 and at December 31, 2015 is presented in the following table: June 30, 2016 December 31, 2015 June 30, 2015 Commercial Real estate $ 1,227,000 $ 915,000 $ 1,538,000 Construction 46,000 238,000 208,000 Other 378,000 66,000 429,000 Municipal — — — Residential Term 4,291,000 5,260,000 5,698,000 Construction — — — Home equity line of credit 421,000 893,000 964,000 Consumer 115,000 — 95,000 Total $ 6,478,000 $ 7,372,000 $ 8,932,000 Impaired loans include troubled debt restructured and loans placed on non-accrual. These loans are measured at the present value of expected future cash flows discounted at the loan's effective interest rate or at the fair value of the collateral if the loan is collateral dependent. If the measure of an impaired loan is lower than the recorded investment in the loan and estimated selling costs, a specific reserve is established for the difference, or, in certain situations, if the measure of an impaired loan is lower than the recorded investment in the loan and estimated selling costs, the difference is written off.

To determine whether or not a loan should be classified as a TDR, Management evaluates a loan based upon the following criteria: • The borrower demonstrates financial difficulty; common indicators include past due status with bank obligations, substandard credit bureau reports, or an inability to refinance with another lender, and • The Company has granted a concession; common concession types include maturity date extension, interest rate adjustments to below market pricing, and deferment of payments. As of June 30, 2016 , the Company had 78 loans with a value of $22,595,000 that have been classified as TDRs. This compares to 84 loans with a value of $23,923,000 and 88 loans with a value of $25,791,000 classified as TDRs as of December 31, 2015 and June 30, 2015 , respectively. The impairment carried as a specific reserve in the allowance for loan losses is calculated by present valuing the expected cash flows on the loan at the original interest rate, or, for collateral-dependent loans, using the fair value of the collateral less costs to sell.

Allowance for Loan Losses

Allowance for Loan Losses	6 Months Ended
	Jun. 30, 2016
Receivables [Abstract]
Allowance for Loan Losses	Allowance for Loan Losses The Company provides for loan losses through the establishment of an allowance for loan losses which represents an estimated reserve for existing losses in the loan portfolio. A systematic methodology is used for determining the allowance that includes a quarterly review process, risk rating changes, and adjustments to the allowance. The loan portfolio is classified in eight classes and credit risk is evaluated separately in each class. The appropriate level of the allowance is evaluated continually based on a review of significant loans, with a particular emphasis on nonaccruing, past due, and other loans that may require special attention. Other factors include general conditions in local and national economies; loan portfolio composition and asset quality indicators; and internal factors such as changes in underwriting policies, credit administration practices, experience, ability and depth of lending management, among others. The allowance consists of four elements: (1) specific reserves for loans evaluated individually for impairment; (2) general reserves for each portfolio segment based on historical loan loss experience, (3) qualitative reserves judgmentally adjusted for local and national economic conditions, concentrations, portfolio composition, volume and severity of delinquencies and nonaccrual loans, trends of criticized and classified loans, changes in credit policies and underwriting standards, credit administration practices, and other factors as applicable for each portfolio segment; and (4) unallocated reserves. All outstanding loans are considered in evaluating the appropriateness of the allowance. A breakdown of the allowance for loan losses as of June 30, 2016 , December 31, 2015 , and June 30, 2015 , by class of financing receivable and allowance element, is presented in the following tables: As of June 30, 2016 Specific Reserves on Loans Evaluated Individually for Impairment General Reserves on Loans Based on Historical Loss Experience Reserves for Qualitative Factors Unallocated Reserves Total Reserves Commercial Real estate $ 369,000 $ 1,296,000 $ 2,290,000 $ — $ 3,955,000 Construction 97,000 80,000 141,000 — 318,000 Other 158,000 585,000 1,035,000 — 1,778,000 Municipal — — 17,000 — 17,000 Residential Term 326,000 577,000 462,000 — 1,365,000 Construction — 19,000 15,000 — 34,000 Home equity line of credit 28,000 475,000 377,000 — 880,000 Consumer 51,000 341,000 243,000 — 635,000 Unallocated — — — 1,216,000 1,216,000 $ 1,029,000 $ 3,373,000 $ 4,580,000 $ 1,216,000 $ 10,198,000 As of December 31, 2015 Specific Reserves on Loans Evaluated Individually for Impairment General Reserves on Loans Based on Historical Loss Experience Reserves for Qualitative Factors Unallocated Reserves Total Reserves Commercial Real estate $ 89,000 $ 893,000 $ 2,138,000 $ — $ 3,120,000 Construction 302,000 82,000 196,000 — 580,000 Other 8,000 425,000 1,019,000 — 1,452,000 Municipal — — 17,000 — 17,000 Residential Term 326,000 613,000 452,000 — 1,391,000 Construction — 14,000 10,000 — 24,000 Home equity line of credit 29,000 500,000 364,000 — 893,000 Consumer — 331,000 235,000 — 566,000 Unallocated — — — 1,873,000 1,873,000 $ 754,000 $ 2,858,000 $ 4,431,000 $ 1,873,000 $ 9,916,000 As of June 30, 2015 Specific Reserves on Loans Evaluated Individually for Impairment General Reserves on Loans Based on Historical Loss Experience Reserves for Qualitative Factors Unallocated Reserves Total Reserves Commercial Real estate $ 225,000 $ 1,017,000 $ 1,701,000 $ — $ 2,943,000 Construction 275,000 161,000 269,000 — 705,000 Other 275,000 522,000 874,000 — 1,671,000 Municipal — — 16,000 — 16,000 Residential Term 501,000 303,000 380,000 — 1,184,000 Construction — 12,000 15,000 — 27,000 Home equity line of credit 31,000 584,000 303,000 — 918,000 Consumer — 373,000 207,000 — 580,000 Unallocated — — — 1,864,000 1,864,000 $ 1,307,000 $ 2,972,000 $ 3,765,000 $ 1,864,000 $ 9,908,000 Qualitative adjustment factors are taken into consideration when determining reserve estimates. These adjustment factors are based upon Management's evaluation of various current conditions, including those listed below. • General economic conditions. • Credit quality trends with emphasis on loan delinquencies, nonaccrual levels and classified loans. • Recent loss experience in particular segments of the portfolio. • Loan volumes and concentrations, including changes in mix. • Other factors, including changes in quality of the loan origination; loan policy changes; changes in credit risk management processes; Bank regulatory and external loan review examination results. The qualitative portion of the allowance for loan losses was 0.44% of related loans as of June 30, 2016 and 0.45% as of December 31, 2015 . The qualitative portion increased $149,000 between December 31, 2015 and June 30, 2016 due to an increase in loans outstanding. Due to the increased commercial loan volume and potential weaknesses in a small number of credits which are currently performing, the Company is carrying a $1,000,000 overlay in qualitative reserves. The unallocated component of the allowance totaled $1,216,000 at June 30, 2016 , or 11.9% of the total reserve, down from the first quarter 2016 and is directionally consistent with our improved credit quality. This compares to $1,873,000 or 18.9% as of December 31, 2015 . Changes in various elements of the allowance caused the period-to-period decrease. Management feels the change in the unallocated is consistent with improvement in credit quality and the effect of loan portfolio growth. The allowance for loan losses as a percent of total loans stood at 0.98% as of June 30, 2016 . This compares to 1.00% of total loans as of December 31, 2015 and 1.03% of total loans as of June 30, 2015 . Commercial loans are comprised of three major classes, commercial real estate loans, commercial construction loans and other commercial loans. Commercial real estate is primarily comprised of loans to small businesses collateralized by owner-occupied real estate, while other commercial is primarily comprised of loans to small businesses collateralized by plant and equipment, commercial fishing vessels and gear, and limited inventory-based lending. Commercial real estate loans typically have a maximum loan-to-value of 80% based upon current appraisal information at the time the loan is made. Municipal loans are comprised of loans to municipalities in Maine for capitalized expenditures, construction projects or tax-anticipation notes. All municipal loans are considered general obligations of the municipality and as such are collateralized by the taxing ability of the municipality for repayment of debt. Construction, land and land development loans, both commercial and residential, comprise a small portion of the portfolio, and at 21.4% of capital are below the regulatory limit of 100.0% of capital at June 30, 2016 . Construction loans and non-owner-occupied commercial real estate loans are at 105.6% of total capital, below the regulatory limit of 300.0% of capital at June 30, 2016 . The process of establishing the allowance with respect to the commercial loan portfolio begins when a loan officer initially assigns each loan a risk rating, using established credit criteria. Approximately 50% of the outstanding loans and commitments are subject to review and validation annually by an independent consulting firm, as well as periodically by the Company's internal credit review function. The methodology employs Management's judgment as to the level of losses on existing loans based on internal review of the loan portfolio, including an analysis of a borrower's current financial position, and the consideration of current and anticipated economic conditions and their potential effects on specific borrowers and or lines of business. In determining the Company's ability to collect certain loans, Management also considers the fair value of underlying collateral. The risk rating system has eight levels, defined as follows: 1 Strong Credits rated "1" are characterized by borrowers fully responsible for the credit with excellent capacity to pay principal and interest. Loans rated "1" may be secured with acceptable forms of liquid collateral. 2 Above Average Credits rated "2" are characterized by borrowers that have better than average liquidity, capitalization, earnings and/or cash flow with a consistent record of solid financial performance. 3 Satisfactory Credits rated "3" are characterized by borrowers with favorable liquidity, profitability and financial condition with adequate cash flow to pay debt service. 4 Average Credits rated "4" are characterized by borrowers that present risk more than 1, 2 and 3 rated loans and merit an ordinary level of ongoing monitoring. Financial condition is on par or somewhat below industry averages while cash flow is generally adequate to meet debt service requirements. 5 Watch Credits rated "5" are characterized by borrowers that warrant greater monitoring due to financial condition or unresolved and identified risk factors. 6 Other Assets Especially Mentioned (OAEM) Loans in this category are currently protected but are potentially weak and constitute an undue and unwarranted credit risk, but not to the point of justifying a classification of substandard. OAEM have potential weaknesses which may, if not checked or corrected, weaken the asset or inadequately protect the Company's credit position at some future date. 7 Substandard Loans in this category are inadequately protected by the paying capacity of the borrower or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Substandard loans are characterized by the distinct possibility that the Company may sustain some loss if the deficiencies are not corrected. 8 Doubtful Loans classified "Doubtful" have the same weaknesses as those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, based on currently existing facts, conditions, and values, highly questionable and improbable. The possibility of loss is high, but because of certain important and reasonably specific pending factors which may work to the advantage and strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined.

This determination is based on circumstances specific to a borrower including repayment ability, analysis of collateral and other factors as applicable. Residential loans are comprised of two classes: term loans, which include traditional amortizing home mortgages, and construction loans, which include loans for owner-occupied residential construction. Residential loans typically have a 75% to 80% loan to value based upon current appraisal information at the time the loan is made. Home equity loans and lines of credit are typically written to the same underwriting standards. Consumer loans are primarily amortizing loans to individuals collateralized by automobiles, pleasure craft and recreation vehicles, typically with a maximum loan to value of 80% to 90% of the purchase price of the collateral. Consumer loans also include a small amount of unsecured short-term time notes to individuals. Residential loans, consumer loans and home equity lines of credit are segregated into homogeneous pools with similar risk characteristics. Trends and current conditions are analyzed and historical loss experience is adjusted accordingly. Quantitative and qualitative adjustment factors for these segments are consistent with those for the commercial and municipal classes. Certain loans in the residential, home equity lines of credit and consumer classes identified as having the potential for further deterioration are analyzed individually to confirm impairment status, and to determine the need for a specific reserve; however there is no formal rating system used for these classes. Consumer loans greater than 120 days past due are generally charged off. Residential loans 90 days or more past due are placed on non-accrual status unless the loans are both well secured and in the process of collection. One- to four-family residential real estate loans and home equity loans are written down or charged-off no later than 180 days past due, or for residential real estate secured loans having a borrower in bankruptcy, within 60 days of receipt of notification of filing from the bankruptcy court, whichever is sooner. This is subject to completion of a current assessment of the value of the collateral with any outstanding loan balance in excess of the fair value of the property, less costs to sell, written down or charged-off.

Stock Options and Stock-Based Compensation	Stock Options and Stock-Based Compensation At the 2010 Annual Meeting, shareholders approved the 2010 Equity Incentive Plan (the "2010 Plan"). This reserves 400,000 shares of common stock for issuance in connection with stock options, restricted stock awards and other equity based awards to attract and retain the best available personnel, provide additional incentive to officers, employees and non-employee Directors and promote the success of our business. Such grants and awards will be structured in a manner that does not encourage the recipients to expose the Company to undue or inappropriate risk. Options issued under the 2010 Plan will qualify for treatment as incentive stock options for purposes of Section 422 of the Internal Revenue Code. Other compensation under the 2010 Plan will qualify as performance-based for purposes of Section 162(m) of the Internal Revenue Code, and will satisfy NASDAQ guidelines relating to equity compensation. As of June 30, 2016 , 108,710 shares of restricted stock had been granted under the 2010 Plan, of which 67,064 shares remain restricted as of June 30, 2016 as detailed in the following table: Year Granted Vesting Term (In Years) Shares Remaining Term (In Years) 2012 5.0 7,996 0.5 2013 5.0 14,776 1.5 2014 5.0 10,422 2.5 2015 5.0 12,023 3.5 2016 1.0 6,832 0.5 2016 5.0 15,015 4.5 67,064 2.5 The compensation cost related to these restricted stock grants is $1,140,000 and will be recognized over the vesting terms of each grant. In the six months ended June 30, 2016 , $132,000 of expense was recognized for these restricted shares, leaving $623,000 in unrecognized expense as of June 30, 2016 . In the six months ended June 30, 2015 , $148,000 of expense was recognized for restricted shares, leaving $493,000 in unrecognized expense as of June 30, 2015 . The Company established a shareholder-approved stock option plan in 1995 (the "1995 Plan"), under which the Company granted options to employees for 600,000 shares of common stock. Only incentive stock options were granted under the 1995 Plan. The option price of each option grant was determined by the Options Committee of the Board of Directors, and in no instance was less than the fair market value on the date of the grant. An option's maximum term was ten years from the date of grant, with 50% of the options granted vesting two years from the date of grant and the remaining 50% vesting five years from the date of grant. As of January 16, 2005, all options under the 1995 Plan had been granted, and as of January 16, 2015, all options granted under the 1995 plan had been exercised or expired.

Stockholders' Equity Note [Abstract]
Preferred and Common Stock	Preferred and Common Stock Preferred Stock On January 9, 2009, the Company issued $25,000,000 in Fixed Rate Cumulative Perpetual Preferred Stock, Series A, to the U.S. Treasury ("Treasury') under the Capital Purchase Program ("the CPP Shares"). The CPP Shares qualified as Tier 1 capital on the Company's books for regulatory purposes and ranked senior to the Company's common stock and senior or at an equal level in the Company's capital structure to any other shares of preferred stock the Company may issue in the future. In three separate transactions in 2012 and 2013, the Company repurchased all of the CPP shares from the Treasury. Incident to such issuance of the CPP shares, the Company issued to the Treasury warrants (the "Warrants") to purchase up to 225,904 shares of the Company's common stock at a price per share of $16.60 (subject to adjustment). The Warrants (and any shares of common stock issuable pursuant to the Warrants) are freely transferable by Treasury to third parties. The Warrants have a term of ten years and could be exercised by Treasury or a subsequent holder at any time or from time to time during their term. To the extent they had not previously been exercised, the Warrants will expire after ten years. The Warrants were unchanged as a result of the CPP Shares repurchase transactions. In May 2015, the Treasury sold all of the Warrants to private parties. In accordance with the contractual terms of the Warrants, the number of shares issuable upon exercise of the warrants and strike price were adjusted at the time of the sale. As a result of this transaction, the number of issuable shares under the Warrants now stands at 226,819 shares with a strike price of $16.53 per share. Common Stock Proceeds from sale of common stock totaled $258,000 and $225,000 for the six months ended June 30, 2016 and 2015 , respectively.

The potentially dilutive securities are unvested shares of restricted stock granted to certain key members of Management and the warrants. The number of dilutive shares is calculated using the treasury method, assuming that all warrants were exercisable at the end of each period. Warrants that are out-of-the-money are not considered in the calculation of dilutive earnings per share as the effect would be anti-dilutive. The following table presents the number of warrants outstanding as of June 30, 2016 and 2015 and the amount for which the average market price at period end is above or below the strike price: Outstanding In-the-Money Out-of-the-Money For the three and six months ended June 30, 2016 Warrants to private parties 226,819 226,819 — Total 226,819 226,819 — For the three and six months ended June 30, 2015 Warrants issued to Treasury 226,819 226,819 — Total 226,819 226,819 —

Employee Benefit Plans	Employee Benefit Plans 401(k) Plan The Bank has a defined contribution plan available to substantially all employees who have completed 3 months of service. Employees may contribute up to Internal Revenue Service ("IRS") determined limits and the Bank may match employee contributions not to exceed 3.0% of compensation depending on contribution level. Subject to a vote of the Board of Directors, the Bank may also make a profit-sharing contribution to the Plan. Such contribution equaled 2.0% of each eligible employee's compensation in 2015 . The amount for 2016 has not been established. The expense related to the 401(k) plan was $226,000 and $232,000 for the six months ended June 30, 2016 and 2015 , respectively. Deferred Compensation and Supplemental Retirement Benefits The Bank also provides unfunded, non-qualified deferred compensation payable over two years , as well as unfunded supplemental retirement benefits for certain officers, payable in installments over 20 years upon retirement or death. The agreements consist of individual contracts with differing characteristics that, when taken together, do not constitute a postretirement plan. The costs for these benefits are recognized over the service periods of the participating officers in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 712 "Compensation – Nonretirement Postemployment Benefits". The expense of these supplemental retirement benefits was $108,000 for the six months ended June 30, 2016 and $156,000 for the same period in 2015 . As of June 30, 2016 , the associated accrued liability included in other liabilities in the balance sheet was $3,083,000 compared to $3,088,000 and $3,049,000 at December 31, 2015 and June 30, 2015 , respectively. Post-Retirement Benefit Plans The Bank sponsors two post-retirement benefit plans. One plan currently provides a subsidy for health insurance premiums to certain retired employees and a future subsidy for seven active employees who were age 50 and over in 1996. These subsidies are based on years of service and range between $40 and $1,200 per month per person. The other plan provides life insurance coverage to certain retired employees and health insurance for retired directors. None of these plans are pre-funded. The Company utilizes FASB ASC Topic 712 to recognize the overfunded or underfunded status of a defined benefit postretirement plan as an asset or liability in its balance sheet and to recognize changes in the funded status in the year in which the changes occur through comprehensive income. The following table sets forth the accumulated postretirement benefit obligation and funded status: At or for the six months ended June 30, 2016 2015 Change in benefit obligation Benefit obligation at beginning of year $ 1,967,000 $ 1,928,000 Service cost — — Interest cost 42,000 36,000 Benefits paid (60,000 ) (52,000 ) Benefit obligation at end of period $ 1,949,000 $ 1,912,000 Funded status Benefit obligation at end of period $ (1,949,000 ) $ (1,912,000 ) Unamortized loss 240,000 192,000 Accrued benefit cost at end of period $ (1,709,000 ) $ (1,720,000 ) The following table sets forth the net periodic pension cost: For the six months ended June 30, For the quarter ended June 30, 2016 2015 2016 2015 Components of net periodic benefit cost Service cost $ — $ — $ — $ — Interest cost 42,000 36,000 21,000 18,000 Net periodic benefit cost $ 42,000 $ 36,000 $ 21,000 $ 18,000 Amounts not yet reflected in net periodic benefit cost and included in accumulated other comprehensive income (loss) are as follows: June 30, December 31, 2015 June 30, Unamortized net actuarial loss $ (240,000 ) $ (240,000 ) $ (192,000 ) Deferred tax benefit at 35% 84,000 84,000 67,000 Net unrecognized postretirement benefits included in accumulated other comprehensive income (loss) $ (156,000 ) $ (156,000 ) $ (125,000 ) A weighted average discount rate of 4.25% was used in determining the accumulated benefit obligation and the net periodic benefit cost. The assumed health care cost trend rate is 7.0% . The measurement date for benefit obligations was as of year-end for prior years presented. The expected benefit payments for all of 2016 are $121,000 . Plan expense for 2016 is estimated to be $85,000 . A 1% change in trend assumptions would create an approximate change in the same direction of $100,000 in the accumulated benefit obligation, $7,000 in the interest cost and $1,000 in the service cost.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Derivative Instruments	Financial Derivative Instruments As part of its overall asset and liability management strategy, the Company periodically uses derivative instruments to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. The Company’s interest rate risk management strategy involves modifying the re-pricing characteristics of certain assets or liabilities so that changes in interest rates do not have a significant effect on net interest income. The Company recognizes its derivative instruments on the consolidated balance sheet at fair value. On the date the derivative instrument is entered into, the Company designates whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). The Company formally documents relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking hedge transactions. The Company also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of hedged items. Changes in fair value of derivative instruments that are highly effective and qualify as cash flow hedges are recorded in other comprehensive income or loss. Any ineffective portion is recorded in earnings. The Company discontinues hedge accounting when it is determined that the derivative is no longer highly effective in offsetting changes of the hedged risk on the hedged item, or management determines that the designation of the derivative as a hedging instrument is no longer appropriate. In 2016, interest rate swaps were contracted to limit the Company’s exposure to rising interest rates on short-term liabilities indexed to one-month London Inter-bank Offered Rates (LIBOR). The interest rate swaps were designated as cash flow hedges. The details of the interest rate swap agreements are as follows: As of June 30 2016 2015 Notional Amount Effective Date Maturity Date Variable Index Received Fixed Rate Paid Fair Value (1) Fair Value (1) $ 30,000,000 June 28, 2016 June 28, 2021 1-Month USD LIBOR 0.940 % $ (153,000 ) $ — $ 20,000,000 June 27, 2016 June 27, 2021 1-Month USD LIBOR 0.893 % $ (55,000 ) — $ 50,000,000 $ (208,000 ) $ — (1) Presented within other liabilities in the consolidated balance sheet. The Company would reclassify unrealized gains or losses accounted for within accumulated other comprehensive income (loss) into earnings if the interest rate swaps were to become ineffective or the swaps were to terminate. In the next 12 months, the Company does not believe it will be required to reclassify any unrealized gains or losses accounted for within accumulated other comprehensive income (loss) into earnings as a result of ineffectiveness or swap termination. Amounts paid or received under the swaps are reported in interest expense in the statement of income, and in interest paid in the statement of cash flows.

Transfers and Servicing [Abstract]
Mortgage Servicing Rights	Mortgage Servicing Rights FASB ASC Topic 860 "Transfers and Servicing" requires all separately recognized servicing assets and servicing liabilities to be initially measured at fair value, if practicable. The Company's servicing assets and servicing liabilities are reported using the amortization method and carried at the lower of amortized cost or fair value by strata. In evaluating the carrying values of mortgage servicing rights, the Company obtains third party valuations based on loan level data including note rate, type and term of the underlying loans. The model utilizes several assumptions, the most significant of which is loan prepayments, calculated using a three -months moving average of weekly prepayment data published by the Public Securities Association (PSA) and modeled against the serviced loan portfolio, and the discount rate to discount future cash flows. As of June 30, 2016 , the prepayment assumption using the PSA model was 293 , which translates into an anticipated prepayment rate of 17.58% . The discount rate is the quarterly average 10 year U.S. Treasury plus 4.45% . Other assumptions include delinquency rates, foreclosure rates, servicing cost inflation, and annual unit loan cost. All assumptions are adjusted periodically to reflect current circumstances. Amortization of mortgage servicing rights, as well as write-offs due to prepayments of the related mortgage loans, are recorded as a charge against mortgage servicing fee income. For the six months ended June 30, 2016 and 2015 , servicing rights capitalized totaled $173,000 and $227,000 , respectively. Servicing rights capitalized for the three-month periods ended June 30, 2016 and 2015 , were $173,000 and $163,000 respectively. Servicing rights amortized for the six months ended June 30, 2016 and 2015 , were $212,000 and $221,000 , respectively. The fair value of servicing rights was $1,489,000 , $1,915,000 and $1,914,000 at June 30, 2016 , December 31, 2015 and June 30, 2015 , respectively. The Bank serviced loans for others totaling $229,924,000 , $223,610,000 and $217,367,000 at June 30, 2016 , December 31, 2015 , and June 30, 2015 , respectively.

Fair Value

Fair Value	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Certain assets and liabilities are recorded at fair value to provide additional insight into the Company's quality of earnings. Some of these assets and liabilities are measured on a recurring basis while others are measured on a nonrecurring basis, with the determination based upon applicable existing accounting pronouncements. For example, securities available for sale are recorded at fair value on a recurring basis. Other assets, such as, other real estate owned and impaired loans, are recorded at fair value on a nonrecurring basis using the lower of cost or market methodology to determine impairment of individual assets. The Company groups assets and liabilities which are recorded at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. A financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement (with level 1 considered highest and level 3 considered lowest). A brief description of each level follows. Level 1 - Valuation is based upon quoted prices for identical instruments in active markets. Level 2 - Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 - Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates that market participants would use in pricing the asset or liability. Valuation includes use of discounted cash flow models and similar techniques. The fair value methods and assumptions for the Company's financial instruments and other assets measured at fair value are set forth below. Cash, Cash Equivalents and Interest-Bearing Deposits in Other Banks The carrying values of cash equivalents, due from banks and federal funds sold approximate their relative fair values. As such, the Company classifies these financial instruments as Level 1. Investment Securities The fair values of investment securities are estimated by independent providers using a market approach with observable inputs, including matrix pricing and recent transactions. In obtaining such valuation information from third parties, the Company has evaluated their valuation methodologies used to develop the fair values in order to determine whether the valuations are representative of an exit price in the Company's principal markets. The Company's principal markets for its securities portfolios are the secondary institutional markets, with an exit price that is predominantly reflective of bid level pricing in those markets. Fair values are calculated based on the value of one unit without regard to any premium or discount that may result from concentrations of ownership of a financial instrument, possible tax ramifications, or estimated transaction costs. If these considerations had been incorporated into the fair value estimates, the aggregate fair value could have been changed. The carrying values of restricted equity securities approximate fair values. As such, the Company classifies investment securities as Level 2. Loans Held for Sale Loans held for sale are recorded at the lower of carrying value or fair value. The fair value of mortgage loans held for sale is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, the Company classifies mortgage loans held for sale as Level 2. Loans Fair values are estimated for portfolios of loans with similar financial characteristics. The fair values of performing loans are calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest risk inherent in the loan. The estimates of maturity are based on the Company's historical experience with repayments for each loan classification, modified, as required, by an estimate of the effect of current economic and lending conditions, and the effects of estimated prepayments. Assumptions regarding credit risk, cash flows, and discount rates are judgmentally determined using available market information and specific borrower information. Management has made estimates of fair value using discount rates that it believes to be reasonable. However, because there is no market for many of these financial instruments, Management has no basis to determine whether the fair value presented above would be indicative of the value negotiated in an actual sale. As such, the Company classifies loans as Level 3, except for certain collateral-dependent impaired loans. Fair values of impaired loans are based on estimated cash flows and are discounted using a rate commensurate with the risk associated with the estimated cash flows, or if collateral dependent, discounted to the appraised value of the collateral as determined by reference to sale prices of similar properties, less costs to sell. As such, the Company classifies collateral dependent impaired loans for which a specific reserve results in a fair value measure as Level 2. All other impaired loans are classified as Level 3. Other Real Estate Owned Real estate acquired through foreclosure is initially recorded at fair value. The fair value of other real estate owned is based on property appraisals and an analysis of similar properties currently available. As such, the Company records other real estate owned as nonrecurring Level 2. Mortgage Servicing Rights Mortgage servicing rights represent the value associated with servicing residential mortgage loans. Servicing assets and servicing liabilities are reported using the amortization method and compared to fair value for impairment. In evaluating the fair values of mortgage servicing rights, the Company obtains third party valuations based on loan level data including note rate, type and term of the underlying loans. As such, the Company classifies mortgage servicing rights as Level 2. Accrued Interest Receivable The fair value estimate of this financial instrument approximates the carrying value as this financial instrument has a short maturity. It is the Company's policy to stop accruing interest on loans for which it is probable that the interest is not collectible. Therefore, this financial instrument has been adjusted for estimated credit loss. As such, the Company classifies accrued interest receivable as Level 2. Deposits The fair value of deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. As such, the Company classifies deposits as Level 2. The fair value estimates do not include the benefit that results from the low-cost funding provided by the deposits compared to the cost of borrowing funds in the market. If that value were considered, the fair value of the Company's net assets could increase. Borrowed Funds The fair value of borrowed funds is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently available for borrowings of similar remaining maturities. As such, the Company classifies borrowed funds as Level 2. Derivatives The fair value of interest rate swaps is determined using inputs that are observable in the market place obtained from third parties including yield curves, publicly available volatilities, and floating indexes and, accordingly, are classified as Level 2 inputs. The credit value adjustments associated with derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. As of June 30, 2016 , the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives due to collateral postings. Accrued Interest Payable The fair value estimate approximates the carrying amount as this financial instrument has a short maturity. The Company classifies accrued interest payable as Level 2. Off-Balance-Sheet Instruments Off-balance-sheet instruments include loan commitments. Fair values for loan commitments have not been presented as the future revenue derived from such financial instruments is not significant. Limitations Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These values do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company's financial instruments, fair value estimates are based on Management's judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on- and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Other significant assets and liabilities that are not considered financial instruments include the deferred tax asset, premises and equipment, and other real estate owned. In addition, tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of the estimates.

Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company's various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques using observable inputs when available. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Topic 825 excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. The carrying amount and estimated fair values for financial instruments as of June 30, 2016 were as follows: Carrying value Estimated fair value Level 1 Level 2 Level 3 Financial assets Cash and cash

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Impact of Recently Issued Accounting Standards	Impact of Recently Issued Accounting Standards In January 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The ASU was issued to enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information. This ASU changes how entities account for equity investments that do not result in consolidation and are not accounted for under the equity method of accounting. The ASU also changes certain disclosure requirements and other aspects of U.S. GAAP, including a requirement for public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. The ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The ASU will not have a material effect on the Company's consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The ASU was issued to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Management is reviewing the guidance in the ASU to determine whether it will have a material effect on the Company’s consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. Under the new guidance, which will replace the existing incurred loss model for recognizing credit losses, banks and other lending institutions will be required to recognize the full amount of expected credit losses. The new guidance, which is referred to as the current expected credit loss model, requires that expected credit losses for financial assets held at the reporting date that are accounted for at amortized cost be measured and recognized based on historical experience and current and reasonably supportable forecasted conditions to reflect the full amount of expected credit losses. A modified version of these requirements also applies to debt securities classified as available for sale. The ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within such years. The Company is evaluating the potential impact of the ASU on its consolidated financial statements.

Financial Derivative Instrume25

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Derivative Instruments	As part of its overall asset and liability management strategy, the Company periodically uses derivative instruments to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. The Company’s interest rate risk management strategy involves modifying the re-pricing characteristics of certain assets or liabilities so that changes in interest rates do not have a significant effect on net interest income. The Company recognizes its derivative instruments on the consolidated balance sheet at fair value. On the date the derivative instrument is entered into, the Company designates whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). The Company formally documents relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking hedge transactions. The Company also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of hedged items. Changes in fair value of derivative instruments that are highly effective and qualify as cash flow hedges are recorded in other comprehensive income or loss. Any ineffective portion is recorded in earnings. The Company discontinues hedge accounting when it is determined that the derivative is no longer highly effective in offsetting changes of the hedged risk on the hedged item, or management determines that the designation of the derivative as a hedging instrument is no longer appropriate. In 2016, interest rate swaps were contracted to limit the Company’s exposure to rising interest rates on short-term liabilities indexed to one-month London Inter-bank Offered Rates (LIBOR). The interest rate swaps were designated as cash flow hedges.
