Management reviews securities with unrealized losses for other than temporary impairment. As of June 30, 2014, there were 197 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 175 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. Information regarding securities temporarily impaired as of June 30, 2014 is summarized below:

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, 2014, and 2013, and December 31, 2013, the Bank's investment in FHLB stock totaled $12,875,000. FHLB stock is a non-marketable equity security and therefore is reported at cost, which equals par value.

	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.
	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, 2014 and 2013 and at December 31, 2013 is presented in the following table:

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.

Troubled Debt Restructured
A troubled debt restructured ("TDR") constitutes a restructuring of debt if the Company, 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 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, 2014, the Company had 97 loans with a value of $28,295,000 that have been classified as TDRs. This compares to 99 loans with a value of $29,098,000 and 105 loans with a value of $30,874,000 classified as TDRs as of December 31, 2013 and June 30, 2013, 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.

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, 2014, December 31, 2013, and June 30, 2013, 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 0.41% and 0.40% of related loans as of June 30, 2014 and December 31, 2013, respectively. The qualitative portion increased $170,000 between December 31, 2013 and June 30, 2014 due to slippage in economic factors.
	The unallocated component of the allowance totaled $1,927,000 at June 30, 2014, or 17% of the total reserve. This compares to $1,678,000 as of December 31, 2013. The fluctuation in the unallocated component supports an increase in loan outstandings year-to-date and, in general, 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.
	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 as such 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 22.5% of capital are well under the regulatory guidance of 100.0% of capital at June 30, 2014. Construction loans and non-owner-occupied commercial real estate loans are at 78.3% of total capital, well under regulatory guidance of 300.0% of capital at June 30, 2014.
	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 current sound worth and 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.

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. 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
	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, 2014, 72,684 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	0.5
	2011	5	5,500	1.6
	2012	3	2,027	0.5
	2012	4	2,704	1.7
	2012	5	7,996	2.7
	2013	2	8,530	0.5
	2013	3	3,808	1.6
	2013	5	14,776	3.6
	2014	1	5,086	0.5
	2014	2	10,335	1.6
	2014	5	10,422	4.6
			72,684	2.3
	The compensation cost related to these restricted stock grants is $1,178,000 and will be recognized over the vesting terms of each grant. In the six months ended June 30, 2014, $205,000 of expense was recognized for these restricted shares, leaving $638,000 in unrecognized expense as of June 30, 2014. In the six months ended June 30, 2013, $107,000 of expense was recognized for restricted shares, leaving $540,000 in unrecognized expense as of June 30, 2013.
	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 the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 718 "Compensation – Stock Compensation", to stock-based employee compensation. As of June 30, 2014, 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 June 30, 2014 and changes during the six-month period then ended, is presented below.

	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 ("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 five 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 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 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 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 will expire after ten 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 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 has been 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 transactions and remain outstanding.
	Common Stock
	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 $11,548,000. The Company used these proceeds to repurchase the remaining $10,000,000 of CPP Shares on May 8, 2013. Issuance of common stock for plans totaled $224,000 and $203,000 for the six months ended June 30, 2014 and 2013, respectively.

The number of dilutive shares is calculated using the treasury method, assuming that all options and warrants were exercisable at the end of each period. Options and 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.

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 2013. The amount for 2014 has not been established. The expense related to the 401(k) plan was $227,000 and $199,000 for the six months ended June 30, 2014 and 2013, respectively.
	Supplemental Retirement Benefits
	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 postretirement 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 retirement benefits was $188,000 for the six months ended June 30, 2014 and $155,000 for the same period in 2013. As of June 30, 2014, the associated accrued liability included in other liabilities in the balance sheet was $2,493,000 compared to $2,333,000 and $2,207,000 at December 31, 2013 and June 30, 2013, 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 "Compensation – Nonretirement Postemployment Benefits" 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,
		2014			2013
	Change in benefit obligation
	Benefit obligation at beginning of year	$	1,479,000		$	1,954,000

	Accrued benefit cost at end of period	$	(1,770,000	)	$	(1,764,000	)
	The following table sets forth the net periodic pension cost:

		2014			2013			2014			2013
	Components of net periodic benefit cost

	Interest cost	44,000			52,000			22,000			26,000
	Amortization of unrecognized transition obligation	—			5,000			—			—
	Amortization of accumulated losses	—			4,000			—			6,000
	Net periodic benefit cost	$	54,000		$	69,000		$	27,000		$	36,000
	Amounts not yet reflected in net periodic benefit cost and included in accumulated other comprehensive income (loss) are as follows:
		June 30,			31-Dec-13			June 30,
		2014						2013
	Unamortized net actuarial gain (loss)	$	289,000		$	289,000		$	(182,000	)
		289,000			289,000			(182,000		)
	Deferred tax expense (benefit) at 35%	(101,000		)	(101,000		)	67,000
	Net unrecognized postretirement benefits included in accumulated other comprehensive income (loss)	$	188,000		$	188,000		$	(115,000	)
	A weighted average discount rate of 4.5% 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 the third quarter of 2014 are $26,000 and the expected benefit payments for all of 2014 are $102,000. Plan expense for 2014 is estimated to be $112,000. 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.

	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.
	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 noninterest expense in the consolidated statements of income and comprehensive income (loss) and is deductible for tax purposes.
	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 for GAAP but is amortizable for tax purposes.
	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.
	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.
	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	$	326,000
	2015	43,000
	2016	43,000
	2017	43,000
	2018	43,000
	Thereafter	174,000

Transfers and Servicing [Abstract]	'
Mortgage Servicing Rights	'
	Mortgage Servicing Rights
	FASB ASC Topic 940 "Financial Services – Mortgage Banking" 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-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 June 30, 2014, the prepayment assumption using the PSA model was 173, which translates into an anticipated prepayment rate of 10.36%. The discount rate is the quarterly average 10 year U.S. Treasury plus 4.93%. 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, 2014 and 2013, servicing rights capitalized totaled $130,000 and $479,000, respectively. Servicing rights capitalized for the three-month periods ended June 30, 2014 and 2013, were $49,000 and $224,000, respectively. Servicing rights amortized for the six-month periods ended June 30, 2014 and 2013, were $226,000 and $265,000, respectively. The fair value of servicing rights was $2,123,000, $1,948,000 and $1,757,000 at June 30, 2014, December 31, 2013 and June 30, 2013, respectively. The Bank serviced loans for others totaling $210,141,000, $211,634,000 and $212,106,000 at June 30, 2014, December 31, 2013, and June 30, 2013, respectively.

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 or partial charge off 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.
	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 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. 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, 2014 were as follows:

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]	'
Impact of Recently Issued Accounting Standards	'
	Impact of Recently Issued Accounting Standards
	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 May 2014, the FASB Issued ASU No. 2014-09, Revenue from Contracts with Customers. The ASU was issued to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and International Financial Reporting Standards. The ASU is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company is currently evaluating the potential impact of the ASU on its consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-11, Transfers and Servicing: Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The ASU was issued to respond to concerns about current accounting and disclosures for repurchase agreements and similar transactions. The concern was that under current accounting guidance there is an unnecessary distinction between the accounting for different types of repurchase agreements. Under current guidance, the repurchase-to-maturity transactions are accounted for as sales with forward agreements, whereas repurchase agreements that settle before the maturity of the transferred financial asset are accounted for as secured borrowings. The ASU amendments require new disclosures for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions accounted for as secured borrowings. The ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The ASU will not have a material effect on the Company's consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation: Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The ASU was issued because current U.S. GAAP does not contain explicit guidance on how to account for share-based payments when a performance target could be achieved after the requisite service period. The ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The ASU will not have a material effect on the Company's consolidated financial statements.
