Summary of Significant Accounting Policies	'
	Summary of Significant Accounting Policies
	Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and the Bank. All intercompany accounts and transactions have been eliminated in consolidation.
	Subsequent Events
	Events occurring subsequent to December 31, 2013, have been evaluated as to their potential impact to the financial statements.
	Use of Estimates in Preparation of Financial Statements
	In preparing the financial statements in accordance with accounting principles generally accepted in the United States of America, Management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the balance sheet and revenues and expenses for the reporting period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for loan losses, goodwill, the valuation of mortgage servicing rights, and other-than-temporary impairment of securities.
	Investment Securities
	Investment securities are classified as available for sale or held to maturity when purchased. There are no trading account securities. Securities available for sale consist primarily of debt securities which Management intends to hold for indefinite periods of time. They may be used as part of the Bank's funds management strategy, and may be sold in response to changes in interest rates or prepayment risk, changes in liquidity needs, or for other reasons. They are accounted for at fair value, with unrealized gains or losses adjusted through shareholders' equity, net of related income taxes. The cost basis is adjusted for the amortization of premiums and accretion of discounts. Securities to be held to maturity consist primarily of debt securities which Management has acquired solely for long-term investment purposes, rather than for purposes of trading or future sale. For securities to be held to maturity, Management has the intent and the Bank has the ability to hold such securities until their respective maturity dates. Such securities are carried at cost adjusted for the amortization of premiums and accretion of discounts. Investment securities transactions are accounted for on a settlement date basis; reported amounts would not be materially different from those accounted for on a trade date basis. Gains and losses on the sales of investment securities are determined using the amortized cost of the specifically identified security. For declines in the fair value of individual debt securities available for sale below their cost that are deemed to be other than temporary, where the Company does not intend to sell the security and it is more likely than not that the Company will not be required to sell the security before recovery of its amortized cost basis, the other-than-temporary decline in the fair value of the debt security related to 1) credit loss is recognized in earnings and 2) other factors is recognized in other comprehensive income or loss. Credit loss is deemed to exist if the present value of expected future cash flows using the effective rate at acquisition is less than the amortized cost basis of the debt security. For individual debt securities where the Company intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost, the other-than-temporary impairment is recognized in earnings equal to the entire difference between the security's cost basis and its fair value at the balance sheet date.
	Loans Held for Sale
	Loans held for sale consist of residential real estate mortgage loans and are carried at the lower of aggregate cost or market value, as determined by current investor yield requirements.
	Loans
	Loans are generally reported at their outstanding principal balances, adjusted for chargeoffs, the allowance for loan losses and any deferred fees or costs to originate loans. Loan commitments are recorded when funded.
	Loan Fees and Costs
	Loan origination fees and certain direct loan origination costs are deferred and recognized in interest income as an adjustment to the loan yield over the life of the related loans. The unamortized net deferred fees and costs are included on the balance sheets with the related loan balances, and the amortization is included with the related interest income.
	Allowance for Loan Losses
	Loans considered to be uncollectible are charged against the allowance for loan losses. The allowance for loan losses is maintained at a level determined by Management to be appropriate to absorb probable losses. This allowance is increased by provisions charged to operating expenses and recoveries on loans previously charged off. Arriving at an appropriate level of allowance for loan losses necessarily involves a high degree of judgment. In determining the appropriate level of allowance for loan losses, Management takes into consideration several factors, including reviews of individual non-performing loans and performing loans listed on the watch report requiring periodic evaluation, loan portfolio size by category, recent loss experience, delinquency trends and current economic conditions. For all loan classes, loans over 30 days past due are considered delinquent. Impaired loans include restructured loans and loans placed on non-accrual status when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement. 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. Management takes into consideration impaired loans in addition to the above mentioned factors in determining the appropriate level of allowance for loan losses.
	Troubled Debt Restructured
	A troubled debt restructured ("TDR") constitutes a restructuring of debt if the Bank, for economic or legal reasons related to the borrower's financial difficulties, grants a concession to the borrower that it would not otherwise consider. To determine whether or not a loan should be classified as a TDR, Management evaluates a loan to first determine if the borrower demonstrates financial difficulty. Common indicators of this include past due status with bank obligations, substandard credit bureau reports, or an inability to refinance with another lender. If the borrower is experiencing financial difficulty and concessions are granted, such as maturity date extension, interest rate adjustments to below market pricing, or a deferment of payments, the loan will generally be classified as a TDR.
	Accrual of Interest Income and Expense
	Interest on loans and investment securities is taken into income using methods which relate the income earned to the balances of loans and investment securities outstanding. Interest expense on liabilities is derived by applying applicable interest rates to principal amounts outstanding. For all classes of loans, recording of interest income on problem loans, which includes impaired loans, ceases when collectibility of principal and interest within a reasonable period of time becomes doubtful. Cash payments received on non-accrual loans, which includes 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.
	Premises and Equipment
	Premises, furniture and equipment are stated at cost, less accumulated depreciation. Depreciation expense is computed by straight-line methods over the asset's estimated useful life.
	Other Real Estate Owned (OREO)
	Real estate acquired by foreclosure or deed in lieu of foreclosure is transferred to OREO and recorded at fair value, less estimated costs to sell, based on appraised value at the date actually or constructively received. Loan losses arising from the acquisition of such property are charged against the allowance for loan losses. Subsequent provisions to reduce the carrying value of a property are recorded to the allowance for OREO losses and a charge to operations on a specific property basis.
	Goodwill and Identified Intangible Assets
	Intangible assets include the excess of the purchase price over the fair value of net assets acquired (goodwill) from the acquisition of FNB Bankshares in 2005 as well as the core deposit intangible related to the same acquisition. The core deposit intangible is amortized on a straight-line basis over ten years. Annual amortization expense for 2013, 2012 and 2011 was $283,000 and the amortization expense for each year until fully amortized will be $283,000. Intangible assets also include the goodwill and core deposit intangible from the 2012 acquisition of a bank branch in Rockland, Maine and a bank building in Bangor, Maine. The core deposit intangible will be amortized on a straight-line basis over ten years. Annual amortization expense for 2013 was $43,000, and the amortization expense for each year until fully amortized will be $43,000. The straight-line basis is used because the Company does not expect significant run off in the core deposits acquired. The Company annually evaluates goodwill, and periodically evaluates other intangible assets, for impairment on the basis of whether these assets are fully recoverable from projected, undiscounted net cash flows of the acquired company. At December 31, 2013, the Company determined goodwill and other intangible assets were not impaired.
	Income Taxes
	Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of assets and liabilities and their respective tax bases, and for tax credits that are available to offset future taxable income. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period the change is enacted.
	Loan Servicing
	Servicing rights are recognized when they are acquired through sale of loans. Capitalized servicing rights are reported in other assets and are amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to amortized cost. Impairment is determined by stratifying rights by predominant characteristics, such as interest rates and terms. Impairment is recognized through a valuation allowance for an individual stratum, to the extent that fair value is less than the capitalized amount for the stratum.
	Post-Retirement Benefits
	The cost of providing post-retirement benefits is accrued during the active service period of the employee or director.
	Earnings Per Share
	Basic earnings per share data are based on the weighted average number of common shares outstanding during each year. Diluted earnings per share gives effect to restricted stock granted and stock options and warrants outstanding, determined by the treasury stock method.
	Comprehensive Income
	Comprehensive income includes net income and other comprehensive income (loss), which is comprised of the change in unrealized gains and losses on securities available for sale, net of tax, and unrecognized gains and loss related to post-retirement benefit costs, net of tax.

	At December 31, 2013, securities with a fair value of $147,074,000 were pledged to secure borrowings from the Federal Home Loan Bank of Boston, public deposits, repurchase agreements, and for other purposes as required by law. This compares to securities with a fair value of $154,817,000, as of December 31, 2012 pledged for the same purpose.
	Gains and losses on the sale of securities available for sale are computed by subtracting the amortized cost at the time of sale from the security's selling price, net of accrued interest to be received.

Management reviews securities with unrealized losses for other than temporary impairment. As of December 31, 2013, there were 304 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 32 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 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 December 31, 2013 and December 31, 2012, the Bank's investment in FHLB stock totaled $12,875,000 and $13,412,000, respectively. FHLB stock is a restricted 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 December 31, 2013. The Bank will continue to monitor its investment in FHLB stock.

	Mortgage Servicing Rights
	At December 31, 2013 and 2012, the Bank serviced loans for others totaling $211,634,000 and $205,859,000, respectively. Net gains from the sale of loans totaled $1,224,000 in 2013, $1,141,000 in 2012, and $646,000 in 2011. In 2013, mortgage servicing rights of $743,000 were capitalized and amortization for the year totaled $515,000. At December 31, 2013, mortgage servicing rights had a fair value of $1,948,000. In 2012, mortgage servicing rights of $330,000 were capitalized and amortization for the year totaled $636,000. At December 31, 2012, mortgage servicing rights had a fair value of $1,228,000.
	The Financial Accounting Standards Board ("FASB") Accounting Standards Codification (the "Codification" or "ASC") Topic 860, "Transfers and Servicing", requires all separately recognized servicing assets and servicing liabilities to be initially measured at fair value, if practicable. Servicing assets and servicing liabilities are reported using the amortization method or the fair value measurement method. 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-month 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 December 31, 2013, the prepayment assumption using the PSA model was 209, which translates into an anticipated prepayment rate of 12.53%. The discount rate is the quarterly average ten-year U.S. Treasury interest rate plus 4.91%. 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.
	Mortgage servicing rights are included in other assets and detailed in the following table:
	As of December 31,	2013			2012
	Mortgage servicing rights	$	7,172,000		$	6,430,000

	Loan balances include net deferred loan costs of $2,086,000 in 2013 and $1,783,000 in 2012. Pursuant to collateral agreements, qualifying first mortgage loans, which were valued at $266,740,000 and $256,378,000 at December 31, 2013 and 2012, respectively, were used to collateralize borrowings from the Federal Home Loan Bank of Boston. In addition, commercial, construction and home equity loans totaling $189,728,000 at December 31, 2013 and 220,520,000 at December 2012, were used to collateralize a standby line of credit at the Federal Reserve Bank of Boston that is currently unused.
	At December 31, 2013 and 2012, non-accrual loans were $16,318,000 and $19,150,000, respectively. As of December 31, 2013, 2012 and 2011, interest income which would have been recognized on these loans, if interest had been accrued, was $917,000, $1,158,000, and $1,052,000, respectively. Loans more than 90 days past due accruing interest totaled $1,043,000 at December 31, 2013 and $1,051,000 at December 31, 2012. The Company continues to accrue interest on these loans because it believes collection of principal and interest is reasonably assured.
	Loans to directors, officers and employees totaled $28,821,000 at December 31, 2013 and $28,707,000 at December 31, 2012. A summary of loans to directors and executive officers, which in the aggregate exceed $60,000, is as follows:

	For all classes, loans are placed on non-accrual status 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 or when principal and interest is 90 days or more past due unless the loan is both well secured and in the process of collection (in which case the loan may continue to accrue interest in spite of its past due status). 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.

Impaired loans include restructured loans 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.

Troubled Debt Restructured
A TDR constitutes a restructuring of debt if the Bank, for economic or legal reasons related to the borrower's financial difficulties, grants a concession to the borrower that it would not otherwise consider. 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 Bank has granted a concession; common concession types include maturity date extension, interest rate adjustments to below market pricing, and deferment of payments.
The Bank applies the same interest accrual policy to TDRs as it does for all classes of loans. As of December 31, 2013, the Bank had 99 loans with a value of $29,098,000 that have been restructured. This compares to 101 loans with a value of $29,955,000 classified as TDRs as of December 31, 2012. The impairment carried as a specific reserve in the allowance for loan losses is calculated by present valuing the cashflow modification on the loan, or, for collateral-dependent loans, using the fair value of the collateral less costs to sell.
The following table shows TDRs by class and the specific reserve as of December 31, 2013:

Allowance for Loan Losses	12 Months Ended

Allowance for Loan and Lease Losses, Adjustments, Net [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 segments and credit risk is evaluated separately in each segment. 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 following table summarizes the composition of the allowance for loan losses, by class of financing receivable and allowance, as of December 31, 2013 and 2012:

	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 December 31, 2013 and 2012, by class of financing receivable and allowance element, is presented in the following tables:

Qualitative adjustment factors are taken into consideration when determining reserve estimates. These adjustment factors are based upon our 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 0.40% of related loans as of December 31, 2013, compared to 0.44% of related loans as of December 31, 2012. The qualitative portion decreased $346,000 between December 31, 2012 and December 31, 2013 due to improving economic factors and Bank credit quality.
The unallocated component totaled $1,678,000 at December 31, 2013 compared to $842,000 as of December 31, 2012. In general, the unallocated component is available to cover imprecision or uncertainties to incorporate the range of probable outcomes inherent in estimates used for the allowance, which may change from period to period. The increase in the unallocated portion is deemed appropriate due to the following:
•	The potentially indeterminate effects of the Federal Reserve’s tapering of its purchases of Treasury bonds and mortgage-backed securities create the possibility of economic uncertainties in the region. Backing out of the quantitative easing, or stimulus program of this size is new. This increases uncertainty in the existing loan portfolio.
•	The U.S. faces a breach of the federal debt ceiling in the first quarter of 2014. Congress must successfully address the issue and failure to do so could bear negative consequences on the global, national, regional and local economies. This also adds to portfolio uncertainty and supports the higher unallocated at the review date.
•	Recently, in 2012 and forward, the Bank’s overall loss rate has exceeded its peer group. This may be due to a general lag effect and/or the extended foreclosure periods mandated by State law. A higher unallocated level is appropriate at this time to support this uncertainty of higher losses.
•	Estimating specific reserves on impaired loans presents challenges as external conditions, factors specific to individual credits and collateral values may change over subsequent periods. A review of specific reserves estimated on year end 2012 impaired loans found that 43% required adjustments in subsequent periods during 2013. This adjustment rate was in line with prior periods suggesting a risk of uncertainty and imprecision in the estimates thereby supporting some level of unallocated for unanticipated changes.
•	A recent internal analysis on OREO property sales found that properties sold, on average, approximately 18% below the appraised value of the property at the time of take in. Based on the analysis, Management has been applying a 20% additional discount factor, exclusive of the estimated costs to sell, to arrive at OREO take-in amounts. This will impact the allowance as these potential additional write downs would be taken against the allowance. The unallocated provides additional funds for these adjustments.
•	From 2009 to the present, a period of historically high losses for the Bank, the required reserve estimate as a percent of total loans averaged 1.33%, and ranged from a low of .88% to a high of 1.60%. In dollars, the range is from $10 million to$13 million. The current allowance level including the unallocated sits in the middle of this range. The present situation indicates improving economic conditions and Bank loan quality. The continued view of the economic recovery is one moving at a slow to moderate pace. Consequently, caution remains appropriate at the evaluation date regarding the direction of the economy, the uncertain consequences of the Federal Reserve monetary tightening and their potential collective impact on Bank loan portfolio quality. Such uncertainties support the unallocated position.
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 75% 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 are collateralized by the taxing ability of the municipality for repayment of debt.
Construction loans, both commercial and residential, comprise a very small portion of the portfolio, and at 24.5% of capital are well under the regulatory guidance of 100.0% of capital at December 31, 2013. Construction loans and non-owner-occupied commercial real estate loans are at 75.6% of total capital, well under regulatory guidance of 300.0% of capital at December 31, 2013.
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 consultant, 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 Bank's credit position at some future date.
7    Substandard
Loans in this category are inadequately protected by the current paying capacity of the borrower or of the collateral, if any. These loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Substandard loans are characterized by the distinct possibility that the Bank may sustain some loss if 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.

Commercial loans are generally charged off when all or a portion of the principal amount is determined to be uncollectible. 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.

	Acquisitions and Intangible Assets
	On October 26, 2012, the Bank completed the purchase of a branch at 63 Union Street in Rockland, Maine, from Camden National Bank that was formerly operated by Bank of America. As part of the transaction, the Bank acquired approximately $32,300,000 in deposits as well as a small volume of loans. On the same date, the Bank completed the purchase of a full-service bank building at 145 Exchange Street in Bangor, Maine, also from Camden National Bank, and opened a full-service branch in this building in the first quarter of 2013. The acquisition allows the Bank to expand its community banking franchise into eastern Maine and expand its presence in Rockland, Maine.
	The acquisition-date estimated fair values of assets acquired and liabilities assumed in Rockland and Bangor were as follows:
	Assets
	Cash	$	25,297,000
	Loans	224,000
	Bank premises and equipment	3,776,000
	Accrued interest receivable and other assets	24,000
	Core deposit intangible	432,000
	Goodwill	2,121,000
	Liabilities
	Deposits	$	31,858,000
	Accrued interest and other liabilities	16,000
	The purchase premium of $2,553,000 was allocated to assets acquired and liabilities assumed based on estimates of fair value at the date of acquisition. The fair value of the deposit accounts assumed was compared to the carrying amounts received and the difference of $432,000 was recorded as core deposit intangible. The core deposit intangible is subject to amortization over the estimated ten-year average life of the acquired core deposit base and will be evaluated for impairment periodically. The amortization expense is included in other noninterest expense in the consolidated statements of income and comprehensive income (loss) and is deductible for tax purposes. Amortization expense was $43,000 in 2013. As of December 31, 2013, the amortization expense related to the core deposit intangible, absent any future impairment, is expected to be as follows:
	2014	$	43,000
	2015	43,000
	2016	43,000
	2017	43,000
	2018	43,000
	Thereafter	174,000
	Total	$	389,000
	The banking facilities were valued at the most recent tax assessed value, which approximates fair value. The loans acquired were recorded at fair value at the time of acquisition. The estimated fair value of the loans acquired is equal to the carrying value. The excess of the purchase price over the fair value of the assets acquired, liabilities assumed, and the amount allocated for core deposit intangible totaled $2,121,000 and was recorded as goodwill. The goodwill is not amortizable but is deductible for tax purposes. Management periodically assesses qualitative factors to determine whether goodwill is impaired. Management is not aware of any such events or circumstances that would cause it to conclude that the goodwill is impaired.
	On January 14, 2005, the Company acquired FNB Bankshares ("FNB") of Bar Harbor, Maine, and its subsidiary, The First National Bank of Bar Harbor. The total value of the transaction was $47,955,000, and all of the voting equity interest of FNB was acquired in the transaction. The transaction was accounted for as a purchase and the excess of purchase price over the fair value of net identifiable assets acquired equaled $27,559,000 and was recorded as goodwill, none of which was deductible for tax purposes. The portion of the purchase price related to the core deposit intangible is being amortized over its expected economic life, and goodwill is evaluated annually for possible impairment under the provisions of FASB ASC Topic 350, "Intangibles – Goodwill and Other".  As of December 31, 2013, in accordance with Topic 350, the Company completed its annual review of goodwill and determined there has been no impairment. The Bank also carries $125,000 in goodwill for a de minimus transaction in 2001.

The carrying value of these investments was $1,026,000 and $1,546,000 at December 31, 2013 and 2012, respectively, and is recorded in other assets. The Company's total exposure to these limited partnerships was $4,526,000 and $5,046,000, at December 31, 2013 and 2012, respectively, which is comprised of the Company's equity investment in the limited partnerships and the balance of a participated loan receivable.
	FASB ASC Topic 740 "Income Taxes" defines the criteria that an individual tax position must satisfy for some or all of the benefits of that position to be recognized in a company's financial statements. Topic 740 prescribes a recognition threshold of more-likely-than-not, and a measurement attribute for all tax positions taken or expected to be taken on a tax return, in order for those tax positions to be recognized in the financial statements. The Company is currently open to audit under the statute of limitations by the Internal Revenue Service for the years ended December 31, 2010 through 2012.

	Borrowed Funds
	Borrowed funds consist of advances from the Federal Home Loan Bank of Boston (FHLB), Treasury Tax & Loan Notes, and securities sold under agreements to repurchase with municipal and commercial customers. Pursuant to collateral agreements, FHLB advances are collateralized by all stock in FHLB, qualifying first mortgage loans, U.S. Government and Agency securities not pledged to others, and funds on deposit with FHLB. As of December 31, 2013, the Bank's total FHLB borrowing capacity, based on its holding of FHLB stock, was $234,404,000 of which $49,800,000 was unused and available for additional borrowings. All FHLB advances as of December 31, 2013, had fixed rates of interest until their respective maturity dates. Securities sold under agreements to repurchase include U.S. agencies securities and other securities. Repurchase agreements have maturity dates ranging from one to 365 days. The Bank also has in place $48,000,000 in credit lines with correspondent banks and a credit facility of $131,000,000 with the Federal Reserve Bank of Boston using commercial and home equity loans as collateral which are currently not in use.

General Discussion of Pension and Other Postretirement Benefits [Abstract]	'
Employee Benefit Plans	'
	Employee Benefit Plans
	401(k) Plan
	The Bank has a defined contribution plan available to substantially all employees who have completed three months of service. Employees may contribute up to IRS-determined limits and the Bank may provide a match to 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 2013, 2012, and 2011. The expense related to the 401(k) plan was $414,000, $363,000, and $341,000 in 2013, 2012, and 2011, respectively.
	Supplemental Retirement Plan
	The Bank also provides unfunded, non-qualified 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 post-retirement plan. The costs for these benefits are recognized over the service periods of the participating officers in accordance with FASB ASC Topic 712, "Compensation – Nonretirement Postemployment Benefits". The expense of these supplemental plans was $309,000 in 2013, $289,000 in 2012, and $307,000 in 2011. As of December 31, 2013 and 2012, the accrued liability of these plans was $2,333,000 and $2,080,000, 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. The Bank also provides health insurance for retired directors. None of these plans are pre-funded.
	The Company utilizes FASB ASC Topic 712, "Compensation – Nonretirement Postemployment Benefits", to recognize the overfunded or underfunded status of a defined benefit post-retirement plan (other than a multiemployer 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 (loss) of a business entity.
	The following table sets forth the accumulated postretirement benefit obligation and funded status:

	The measurement date for benefit obligations was as of year-end for all years presented. The estimated amount of benefits to be paid in 2014 is $102,000. For years ending 2015 through 2018, the estimated amount of benefits to be paid is $103,000, $117,000, $118,000 and $119,000 respectively, and the total estimated amount of benefits to be paid for years ended 2019 through 2023 is $551,000. Plan expense for 2014 is estimated to be $59,000.
	In accordance with FASB ASC Topic 715, "Compensation – Retirement Benefits", amounts not yet reflected in net periodic benefit cost and included in accumulated other comprehensive income (loss) are as follows:

	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, having a liquidation preference of $1,000 per share, to the U.S. Treasury under the Capital Purchase Program ("the CPP Shares"). The CPP Shares called for cumulative dividends at a rate of 5.0% per year for the first 5 years, and at a rate of 9.0% per year in following years, payable quarterly in arrears on February 15, May 15, August 15 and November 15 of each year.
	On August 24, 2011, the Company repurchased $12,500,000 of the CPP Shares. Almost all of the repayment was made from retained earnings accumulated since the preferred stock was issued in 2009. On March 27, 2013, the Company
	repurchased $2,500,000 of the CPP Shares with funds from its operating account. On May 8, 2013, the Company repurchased
	the remaining $10,000,000 of the CPP Shares using proceeds from the Company's common stock offering in the first quarter of 2013, All the repurchase transactions were approved by the Federal Reserve Bank of Boston, the Company's primary regulator.
	Incident to such issuance, the Company issued to the U.S. 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 and the Company has filed a registration statement with the Securities and Exchange Commission to allow for possible resale of such securities.
	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 would expire after 10 years. Treasury will not vote any shares of common stock it receives upon exercise of the Warrants, but that restriction would not apply to third parties to whom Treasury transferred the Warrants. The Warrants (and any common stock issued upon exercise of the Warrants) could be transferred to third parties separately from the CPP Shares. The proceeds from the sale of the CPP Shares were allocated between the CPP Shares and Warrants based on their relative fair values on the issue date. The fair value of the Warrants was determined using the Black-Scholes model which includes the following assumptions: common stock price of $16.60 per share, dividend yield of 4.70%, stock price volatility of 24.43%, and a risk-free interest rate of 2.01%. The discount on the CPP Shares was based on the value that was allocated to the Warrants upon issuance, and is being accreted back to the value of the CPP Shares over a five-year period (the expected life of the shares upon issuance) on a straight-line basis. The Warrants were unchanged as a result of the CPP Shares repurchase transaction and remain outstanding.
	Common Stock
	The Company has reserved 700,000 shares of its common stock to be made available to directors and employees who elect to participate in the stock purchase or savings and investment plans. As of December 31, 2013, 533,796 shares had been issued pursuant to these plans, leaving 166,204 shares available for future use. The issuance price is based on the market price of the stock at issuance date. Sales of stock to directors and employees amounted to 11,385 shares in 2013, 12,451 shares in 2012, and 12,775 shares in 2011.
	In 2001, the Company established a dividend reinvestment plan to allow shareholders to use their cash dividends for the automatic purchase of shares in the Company. When the plan was established, 600,000 shares were registered with the Securities and Exchange Commission, and as of December 31, 2013, 212,588 shares have been issued, leaving 387,412 shares for future use. Participation in this plan is optional and at the individual discretion of each Shareholder. Shares are purchased for the plan from the Company at a price per share equal to the average of the daily bid and asked prices reported on the NASDAQ System for the five trading days immediately preceding, but not including, the dividend payment date. Sales of stock under the Dividend Reinvestment Plan amounted to 12,008 shares in 2013, 14,056 shares in 2012, and 14,387 shares in 2011.
	On March 28, 2013, the Company consummated a fully underwritten offering for 760,771 shares of the Company's common stock, with net proceeds of $11,649,000. The Company used these proceeds to repurchase the remaining $10,000,000 of CPP Shares on May 8, 2013.

	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 December 31, 2013, 46,841 shares of restricted stock had been granted under the 2010 Plan, as detailed in the following table:
	Year	Vesting Term	Shares	Remaining Term
	Granted	(In Years)		(In Years)
	2011	4	1,500	1.1
	2011	5	5,500	2.1

	2013	5	9,699	4.1
			46,841	2.4
	The compensation cost related to these restricted stock grants was $756,000 and will be recognized over the vesting terms of each grant. In 2013, $214,000 of expense was recognized for these restricted shares, leaving $433,000 in unrecognized expense as of December 31, 2013. In 2012, $85,000 of expense was recognized for restricted shares, leaving $207,000 in unrecognized expense as of December 31, 2012.
	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.
	The Company applies the fair value recognition provisions of FASB ASC Topic 718, "Compensation – Stock Compensation", to stock-based employee compensation. As of December 31, 2013, all outstanding options were fully vested and all compensation cost for options had been recognized. A summary of the status of outstanding stock options as of December 31, 2013 and changes during the year then ended, is presented below.

Regulatory Capital Requirements [Abstract]	'
Regulatory Capital Requirements	'
	Regulatory Capital Requirements
	The ability of the Company to pay cash dividends to its shareholders depends primarily on receipt of dividends from its subsidiary, the Bank. The subsidiary may pay dividends to its parent out of so much of its net income as the Bank's directors deem appropriate, subject to the limitation that the total of all dividends declared by the Bank in any calendar year may not exceed the total of its net income of that year combined with its retained net income of the preceding two years and subject to minimum regulatory capital requirements. The amount available for dividends in 2014 will be 2014 earnings plus retained earnings of $9,238,000 from 2013 and 2012.
	The payment of dividends by the Company is also affected by various regulatory requirements and policies, such as the requirements to maintain adequate capital. In addition, if, in the opinion of the applicable regulatory authority, a bank under its jurisdiction is engaged in or is about to engage in an unsafe or unsound practice (which, depending on the financial condition of the bank, could include the payment of dividends), that authority may require, after notice and hearing, that such bank cease and desist from that practice. The Federal Reserve Bank and the Comptroller of the Currency have each indicated that paying dividends that deplete a bank's capital base to an inadequate level would be an unsafe and unsound banking practice. The Federal Reserve Bank, the Comptroller and the Federal Deposit Insurance Corporation have issued policy statements which provide that bank holding companies and insured banks should generally only pay dividends out of current operating earnings.
	In addition to the effect on the payment of dividends, failure to meet minimum capital requirements can also result in mandatory and discretionary actions by regulators that, if undertaken, could have an impact on the Company's operations. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measurements of the Bank's assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank's capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.
	Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios set forth in the table below of Tier 1 capital and Tier 2 or total capital to risk-weighted assets and of Tier 1 capital to average assets. Management believes, as of December 31, 2013, that the Bank meets all capital adequacy requirements to which it is subject.
	As of December 31, 2013, the most recent notification from the Office of the Comptroller of the Currency classified the Bank as well-capitalized under the regulatory framework for prompt corrective action. To be categorized as well-capitalized, the Bank must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the table. There are no conditions or events since this notification that Management believes have changed the institution's category.
	The actual and minimum capital amounts and ratios for the Bank are presented in the following table:
		Actual			For capital			To be well-capitalized

	As of December 31, 2013

	Off-Balance-Sheet Financial Instruments and Concentrations of Credit Risk
	The Bank is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to originate loans, commitments for unused lines of credit, and standby letters of credit. The instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The contract amounts of those instruments reflect the extent of involvement the Bank has in particular classes of financial instruments.
	Commitments for unused lines are agreements to lend to a customer provided there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on Management's credit evaluation of the borrower. The Bank did not incur any losses on its commitments in 2013, 2012 or 2011.
	Standby letters of credit are conditional commitments issued by the Bank to guarantee a customer's performance to a third party, with the customer being obligated to repay (with interest) any amounts paid out by the Bank under the letter of credit. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers.
	The Bank's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for loan commitments and standby letters of credit is represented by the contractual amount of those instruments.
	The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.
	At December 31, 2013 and 2012, the Bank had the following off-balance-sheet financial instruments, whose contract amounts represent credit risk:
	As of December 31,	2013		2012
	Unused lines, collateralized by residential real estate	$	58,265,000	$	56,420,000
	Other unused commitments	48,646,000		45,747,000
	Standby letters of credit	4,086,000		2,700,000
	Commitments to extend credit	7,224,000		6,245,000
	Total	$	118,221,000	$	111,112,000
	The Bank grants residential, commercial and consumer loans to customers principally located in the Mid-Coast and Down East regions of Maine. Collateral on these loans typically consists of residential or commercial real estate, or personal property. Although the loan portfolio is diversified, a substantial portion of borrowers' ability to honor their contracts is dependent on the economic conditions in the area, especially in the real estate sector.

Fair Value Disclosures [Abstract]	'
Fair Value Disclosures	'
	Fair Value Disclosures
	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, mortgage servicing rights, loans held for sale, 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 based on quoted prices for similar securities. 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. As such, the Company classifies investment securities as Level 2. 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.
	Loans Held for Sale
	Loans held for sale are recorded at the lower of carrying value or market 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 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 sales prices of similar properties, less costs to sell. As such, the Company classifies impaired loans as Level 2.
	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 sales prices of similar properties. 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.
	Accrued Interest Payable
	The fair value estimate approximates the carrying amount as this financial instrument has a short maturity. As such, 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.

	Assets and Liabilities Recorded at Fair Value on a Non-Recurring Basis
	The following table presents assets measured at fair value on a nonrecurring basis that have had a fair value adjustment since their initial recognition. Other real estate owned is presented net of an allowance for losses of $330,000 and $373,000 at December 2013 and 2012, respectively. Impaired loans measured at fair value only include impaired loans with a related specific allowance for loan losses and are presented net of their related specific allowance for loan losses of $1,309,000 and $3,539,000 at December 31, 2013 and 2012, respectively. The December 31, 2012 non-recurring fair value table includes all impaired loans with a related allowance. The Company refined its process for identifying impaired loans for purposes of fair value disclosures; accordingly the December 31, 2013 fair value table only includes those impaired loans for which the related allowance results in a fair value measure, as described above.

	Fair Value of Financial Instruments
	FASB ASC Topic 825, "Financial Instruments," requires disclosures of fair value information about financial instruments, whether or not recognized in the balance sheet, if the fair values can be reasonably determined. 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. FASB ASC 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 amounts and estimated fair values for financial instruments as of December 31, 2013 were as follows:

	New Accounting Pronouncements
	In January 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. The amendments in this Update permit entities to make accounting policy elections to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). For those investments in qualified affordable housing projects not accounted for using the proportional amortization method, the ASU requires the investment to be accounted for as an equity method investment or a cost method investment. The amendments in this Update should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments in this ASU are effective for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted.  Management has reviewed the ASU and does not believe that it will have a material effect on the Company's consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The amendments in this Update clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. The amendments in this Update are effective for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Management has reviewed the ASU and does not believe that it will have a material effect on the Company's consolidated financial statements.
	In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified out of Accumulated Comprehensive Income. The ASU adds new disclosure requirements for items reclassified out of accumulated other comprehensive income (AOCI) and is intended to help entities improve the transparency of changes in other comprehensive income and items reclassified out of AOCI in their financial statements. The guidance is effective prospectively for reporting periods beginning after December 15, 2012, with early adoption permitted. The adoption of this new guidance did not have a material effect on the Company's consolidated financial statements.

	The consolidated financial statements include the accounts of the Company and the Bank. All intercompany accounts and transactions have been eliminated in consolidation.
Subsequent Events	'
	Subsequent Events
	Events occurring subsequent to December 31, 2013, have been evaluated as to their potential impact to the financial statements.
Use of Estimates in Preparation of Financial Statements	'
	Use of Estimates in Preparation of Financial Statements
	In preparing the financial statements in accordance with accounting principles generally accepted in the United States of America, Management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the balance sheet and revenues and expenses for the reporting period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near-term relate to the determination of the allowance for loan losses, goodwill, the valuation of mortgage servicing rights, and other-than-temporary impairment of securities.
Investment Securities	'
	Investment Securities
	Investment securities are classified as available for sale or held to maturity when purchased. There are no trading account securities. Securities available for sale consist primarily of debt securities which Management intends to hold for indefinite periods of time. They may be used as part of the Bank's funds management strategy, and may be sold in response to changes in interest rates or prepayment risk, changes in liquidity needs, or for other reasons. They are accounted for at fair value, with unrealized gains or losses adjusted through shareholders' equity, net of related income taxes. The cost basis is adjusted for the amortization of premiums and accretion of discounts. Securities to be held to maturity consist primarily of debt securities which Management has acquired solely for long-term investment purposes, rather than for purposes of trading or future sale. For securities to be held to maturity, Management has the intent and the Bank has the ability to hold such securities until their respective maturity dates. Such securities are carried at cost adjusted for the amortization of premiums and accretion of discounts. Investment securities transactions are accounted for on a settlement date basis; reported amounts would not be materially different from those accounted for on a trade date basis. Gains and losses on the sales of investment securities are determined using the amortized cost of the specifically identified security. For declines in the fair value of individual debt securities available for sale below their cost that are deemed to be other than temporary, where the Company does not intend to sell the security and it is more likely than not that the Company will not be required to sell the security before recovery of its amortized cost basis, the other-than-temporary decline in the fair value of the debt security related to 1) credit loss is recognized in earnings and 2) other factors is recognized in other comprehensive income or loss. Credit loss is deemed to exist if the present value of expected future cash flows using the effective rate at acquisition is less than the amortized cost basis of the debt security. For individual debt securities where the Company intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost, the other-than-temporary impairment is recognized in earnings equal to the entire difference between the security's cost basis and its fair value at the balance sheet date.
Loans Held for Sale	'
	Loans Held for Sale
	Loans held for sale consist of residential real estate mortgage loans and are carried at the lower of aggregate cost or market value, as determined by current investor yield requirements.
Loans	'
	Loans
	Loans are generally reported at their outstanding principal balances, adjusted for chargeoffs, the allowance for loan losses and any deferred fees or costs to originate loans. Loan commitments are recorded when funded.
Loan Fees and Costs	'
	Loan Fees and Costs
	Loan origination fees and certain direct loan origination costs are deferred and recognized in interest income as an adjustment to the loan yield over the life of the related loans. The unamortized net deferred fees and costs are included on the balance sheets with the related loan balances, and the amortization is included with the related interest income.
Allowance for Loan Losses	'
	Allowance for Loan Losses
	Loans considered to be uncollectible are charged against the allowance for loan losses. The allowance for loan losses is maintained at a level determined by Management to be appropriate to absorb probable losses. This allowance is increased by provisions charged to operating expenses and recoveries on loans previously charged off. Arriving at an appropriate level of allowance for loan losses necessarily involves a high degree of judgment. In determining the appropriate level of allowance for loan losses, Management takes into consideration several factors, including reviews of individual non-performing loans and performing loans listed on the watch report requiring periodic evaluation, loan portfolio size by category, recent loss experience, delinquency trends and current economic conditions. For all loan classes, loans over 30 days past due are considered delinquent. Impaired loans include restructured loans and loans placed on non-accrual status when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement. 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. Management takes into consideration impaired loans in addition to the above mentioned factors in determining the appropriate level of allowance for loan losses.
Troubled Debt Restructured	'
	Troubled Debt Restructured
	A troubled debt restructured ("TDR") constitutes a restructuring of debt if the Bank, for economic or legal reasons related to the borrower's financial difficulties, grants a concession to the borrower that it would not otherwise consider. To determine whether or not a loan should be classified as a TDR, Management evaluates a loan to first determine if the borrower demonstrates financial difficulty. Common indicators of this include past due status with bank obligations, substandard credit bureau reports, or an inability to refinance with another lender. If the borrower is experiencing financial difficulty and concessions are granted, such as maturity date extension, interest rate adjustments to below market pricing, or a deferment of payments, the loan will generally be classified as a TDR.
Accrual of Interest Income and Expense	'
	Accrual of Interest Income and Expense
	Interest on loans and investment securities is taken into income using methods which relate the income earned to the balances of loans and investment securities outstanding. Interest expense on liabilities is derived by applying applicable interest rates to principal amounts outstanding. For all classes of loans, recording of interest income on problem loans, which includes impaired loans, ceases when collectibility of principal and interest within a reasonable period of time becomes doubtful. Cash payments received on non-accrual loans, which includes 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.
Premises and Equipment	'
	Premises and Equipment
	Premises, furniture and equipment are stated at cost, less accumulated depreciation. Depreciation expense is computed by straight-line methods over the asset's estimated useful life.
Other Real Estate Owned (OREO)	'
	Other Real Estate Owned (OREO)
	Real estate acquired by foreclosure or deed in lieu of foreclosure is transferred to OREO and recorded at fair value, less estimated costs to sell, based on appraised value at the date actually or constructively received. Loan losses arising from the acquisition of such property are charged against the allowance for loan losses. Subsequent provisions to reduce the carrying value of a property are recorded to the allowance for OREO losses and a charge to operations on a specific property basis.
Goodwill and Identified Intangible Assets	'
	Goodwill and Identified Intangible Assets
	Intangible assets include the excess of the purchase price over the fair value of net assets acquired (goodwill) from the acquisition of FNB Bankshares in 2005 as well as the core deposit intangible related to the same acquisition. The core deposit intangible is amortized on a straight-line basis over ten years. Annual amortization expense for 2013, 2012 and 2011 was $283,000 and the amortization expense for each year until fully amortized will be $283,000. Intangible assets also include the goodwill and core deposit intangible from the 2012 acquisition of a bank branch in Rockland, Maine and a bank building in Bangor, Maine. The core deposit intangible will be amortized on a straight-line basis over ten years. Annual amortization expense for 2013 was $43,000, and the amortization expense for each year until fully amortized will be $43,000. The straight-line basis is used because the Company does not expect significant run off in the core deposits acquired. The Company annually evaluates goodwill, and periodically evaluates other intangible assets, for impairment on the basis of whether these assets are fully recoverable from projected, undiscounted net cash flows of the acquired company. At December 31, 2013, the Company determined goodwill and other intangible assets were not impaired.
Income Taxes	'
	Income Taxes
	Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of assets and liabilities and their respective tax bases, and for tax credits that are available to offset future taxable income. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period the change is enacted
Loan Servicing	'
	Loan Servicing
	Servicing rights are recognized when they are acquired through sale of loans. Capitalized servicing rights are reported in other assets and are amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to amortized cost. Impairment is determined by stratifying rights by predominant characteristics, such as interest rates and terms. Impairment is recognized through a valuation allowance for an individual stratum, to the extent that fair value is less than the capitalized amount for the stratum.
Post-Retirement Benefits	'
	Post-Retirement Benefits
	The cost of providing post-retirement benefits is accrued during the active service period of the employee or director.
Earnings Per Share	'
	Earnings Per Share
	Basic earnings per share data are based on the weighted average number of common shares outstanding during each year. Diluted earnings per share gives effect to restricted stock granted and stock options and warrants outstanding, determined by the treasury stock method.
Comprehensive Income	'
	Comprehensive Income
	Comprehensive income includes net income and other comprehensive income (loss), which is comprised of the change in unrealized gains and losses on securities available for sale, net of tax, and unrecognized gains and loss related to post-retirement benefit costs, net of tax.
Segments	'
	Segments
	The First Bancorp, Inc., through the branches of its subsidiary, The First, N.A., provides a broad range of financial services to individuals and companies in coastal Maine. These services include demand, time, and savings deposits; lending; ATM processing; and investment management and trust services. Operations are managed and financial performance is evaluated on a corporate-wide basis. Accordingly, all of the Company's banking operations are considered by Management to be aggregated in one reportable operating segment.
New Accounting Pronouncements	'
	New Accounting Pronouncements
	In January 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. The amendments in this Update permit entities to make accounting policy elections to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). For those investments in qualified affordable housing projects not accounted for using the proportional amortization method, the ASU requires the investment to be accounted for as an equity method investment or a cost method investment. The amendments in this Update should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments in this ASU are effective for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted.  Management has reviewed the ASU and does not believe that it will have a material effect on the Company's consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The amendments in this Update clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. The amendments in this Update are effective for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Management has reviewed the ASU and does not believe that it will have a material effect on the Company's consolidated financial statements.
	In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified out of Accumulated Comprehensive Income. The ASU adds new disclosure requirements for items reclassified out of accumulated other comprehensive income (AOCI) and is intended to help entities improve the transparency of changes in other comprehensive income and items reclassified out of AOCI in their financial statements. The guidance is effective prospectively for reporting periods beginning after December 15, 2012, with early adoption permitted. The adoption of this new guidance did not have a material effect on the Company's consolidated financial statements.
