	Investment securities will at times depreciate to an unrealized loss position. The Company utilizes the following criteria to assess whether impairment is other than temporary. No one item by itself will necessarily signal that a security should be recognized as an other than temporary impairment.
	1	The fair value of the security has significantly declined from book value.
	2	A downgrade has occurred that lowered the credit rating to below investment grade (below Baa3 by Moody and BBB – by Standard and Poors.)
	3	Dividends have been reduced or eliminated or scheduled interest payments have not been made.
	4	The underwater security has longer than 10 years to maturity and the loss position had existed for more than 3 years.
	5	Management does not possess both the intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value.
	If the impairment is judged to be other than temporary, the cost basis of the individual security shall be written down to fair value, thereby establishing a new cost basis. The new cost basis shall not be changed for subsequent recoveries in fair value. The amount of the write down shall be included in current earnings as a realized loss. The recovery in fair value, if any, shall be recognized in earnings when the security is sold. The table below is presented by category of security and length of time in a continuous loss position. The Company currently does not hold any securities with other than temporary impairment.
	Information pertaining to securities with gross unrealized losses at March 31, 2015 and December 31, 2014, aggregated by investment category and length of time that individual securities have been in a continuous loss position follows:

	Unrealized losses on securities have not been recognized into income because the issuers’ bonds are of high credit quality, values have only been impacted by rate changes, and the Company has the intent and ability to hold the securities for the foreseeable future. Additionally, the decline in value is primarily due to changes in interest rates since the securities were purchased. The fair value is expected to recover as the bonds approach the maturity date.
	Below are the gross realized gains and losses as of March 31 for each of the years presented.

	The net realized gain on sales and related tax expense is a reclassification out of accumulated other comprehensive income (loss). The net realized gain is included in net gain on sale of securities available-for-sale and the related tax expense is included in income tax expense in the condensed consolidated statements of income and comprehensive income.
	The amortized cost and fair value of debt securities at March 31, 2015, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

The Bank uses a nine tier risk rating system to grade its loans. The grade of a loan may change during the life of the loan.
The risk ratings are described as follows.
	1	Zero (0) Unclassified. Any loan which has not been assigned a classification.
	2	One (1) Excellent. Credit to premier customers having the highest credit rating based on an extremely strong financial condition, which compares favorably with industry standards (upper quartile of Risk Management Association ratios). Financial statements indicate a sound earnings and financial ratio trend for several years with satisfactory profit margins and excellent liquidity exhibited. Prime credits may also be borrowers with loans fully secured by highly liquid collateral such as traded stocks, bonds, certificates of deposit, savings account, etc. No credit or collateral exceptions exist and the loan adheres to the Bank’s loan policy in every respect. Financing alternatives would be readily available and would qualify for unsecured credit. This grade is summarized by high liquidity, minimum risk, strong ratios, and low handling costs.
	3	Two (2) Good. Desirable loans of somewhat less stature than Grade 1, but with strong financial statements. Loan supported by financial statements containing strong balance sheets, generally with a leverage position less than 1.50, and a history of profitability. Probability of serious financial deterioration is unlikely. Possessing a sound repayment source (and a secondary source), which would allow repayment in a reasonable period of time. Individual loans backed by liquid personal assets, established history and unquestionable character.
	4	Three (3) Satisfactory. Satisfactory loans of average or slightly above average risk – having some deficiency or vulnerability to changing economic conditions, but still fully collectible. Projects should normally demonstrate acceptable debt service coverage. Generally, customers should have a leverage position less than 2.00. May be some weakness but with offsetting features of other support readily available. Loans that are meeting the terms of repayment.
Loans may be graded 3 when there is no recent information on which to base a current risk evaluation and the following conditions apply:
At inception, the loan was properly underwritten and did not possess an unwarranted level of credit risk:
	a.	At inception, the loan was secured with collateral possessing a loan value adequate to protect the Bank from loss;
	b.	The loan exhibited two or more years of satisfactory repayment with a reasonable reduction of the principal balance;
	c.	During the period that the loan has been outstanding, there has been no evidence of any credit weakness. Some examples of weakness include slow payment, lack of cooperation by the borrower, breach of loan covenants, or the business is in an industry which is known to be experiencing problems. If any of the credit weaknesses is observed, a lower risk grade is warranted.
	5	Four (4) Satisfactory / Monitored. A “4” (Satisfactory/Monitored) risk grade may be established for a loan considered satisfactory but which is of average credit risk due to financial weakness or uncertainty. The loans warrant a higher than average level of monitoring to ensure that weaknesses do not advance. The level of risk in Satisfactory/Monitored classification is considered acceptable and within normal underwriting guidelines, so long as the loan is given management supervision.
	6	Five (5) Special Mention. Loans that possess some credit deficiency or potential weakness which deserves close attention, but which do not yet warrant substandard classification. Such loans pose unwarranted financial risk that, if not corrected, could weaken the loan and increase risk in the future. The key distinctions of a 5 (Special Mention) classification are that (1) it is indicative of an unwarranted level of risk, and (2) weaknesses are considered “potential”, versus “defined”, impairments to the primary source of loan repayment and collateral.
	7	Six (6) Substandard. One or more of the following characteristics may be exhibited in loans classified substandard:
	a.	Loans, which possess a defined credit weakness and the likelihood that a loan will be paid from the primary source, are uncertain. Financial deterioration is underway and very close attention is warranted to ensure that the loan is collected without loss.
	b.	Loans are inadequately protected by the current net worth and paying capacity of the borrower.
	c.	The primary source of repayment is weakened, and the Bank is forced to rely on a secondary source of repayment such as collateral liquidation or guarantees.
	d.	Loans are characterized by the distinct possibility that the Bank will sustain some loss if deficiencies are not corrected.
	e.	Unusual courses of action are needed to maintain a high probability of repayment.
	f.	The borrower is not generating enough cash flow to repay loan principal; however, continues to make interest payments.
	g.	The lender is forced into a subordinate position or unsecured collateral position due to flaws in documentation.
	h.	Loans have been restructured so that payment schedules, terms and collateral represent concessions to the borrower when compared to the normal loan terms.
	i.	The lender is seriously contemplating foreclosure or legal action due to the apparent deterioration in the loan.
	j.	There is significant deterioration in the market conditions and the borrower is highly vulnerable to these conditions.
	8	Seven (7) Doubtful. One or more of the following characteristics may be exhibited in loans classified Doubtful:
	a.	Loans have all of the weaknesses of those classified as Substandard. Additionally, however, these weaknesses make collection or liquidation in full based on existing conditions improbable.
	b.	The primary source of repayment is gone, and there is considerable doubt as to the quality of the secondary source of repayment.
	c.	The possibility of loss is high, but, because of certain important pending factors which may strengthen the loan, loss classification is deferred until its exact status is known. A Doubtful classification is established deferring the realization of the loss.
	9	Eight (8) Loss. Loans are considered uncollectable and of such little value that continuing to carry them as assets on the institution’s financial statements is not feasible. Loans will be classified Loss when it is neither practical nor desirable to defer writing off or reserving all or a portion of a basically worthless asset, even though partial recovery may be possible at some time in the future.

The Bank had approximately $1.3 million of its impaired loans classified as troubled debt restructured (TDR) as of March 31, 2015, $797.2 thousand as of December 31, 2014 and $974.0 thousand as of March 31, 2014. During the first quarter 2015, two new loans were considered TDR. These encompassed one loan that is making interest-only payments, and one loan that is on a modified amortization schedule.

For the three month periods ended March 31, 2015 and 2014, there were no TDRs that subsequently defaulted after modification.
For the majority of the Bank’s impaired loans, the Bank will apply the observable market price methodology. However, the Bank may also utilize a measurement incorporating the present value of expected future cash flows discounted at the loan’s effective rate of interest. To determine observable market price, collateral asset values securing an impaired loan are periodically evaluated. Maximum time for re-evaluation is every 12 months for chattels and titled vehicles and every two years for real estate. In this process, third party evaluations are obtained and heavily relied upon. Until such time that updated appraisals are received, the Bank may discount the collateral value used.
The Bank uses the following guidelines as stated in policy to determine when to realize a charge-off, whether a partial or full loan balance. A charge-off in whole or in part is realized when unsecured consumer loans, credit card credits and overdraft lines of credit reach 90 days delinquency. At 120 days delinquent, secured consumer loans are charged down to the value of the collateral, if repossession of the collateral is assured and/or in the process of repossession. Consumer mortgage loan deficiencies are charged down upon the sale of the collateral or sooner upon the recognition of collateral deficiency. Commercial and agricultural credits are charged down at 120 days delinquency, unless an established and approved work-out plan is in place or litigation of the credit will likely result in recovery of the loan balance. Upon notification of bankruptcy, unsecured debt is charged off. Additional charge-off may be realized as further unsecured positions are recognized.

The Company segregates its ALLL into two reserves: The ALLL and the Allowance for Unfunded Loan Commitments and Letters of Credit (AULC). When combined, these reserves constitute the total Allowance for Credit Losses (ACL).
The AULC is reported within other liabilities on the balance sheet while the ALLL is netted within the loans, net asset line. The ACL presented above represents the full amount of reserves available to absorb possible credit losses.
The following table breaks down the activity within ACL for each loan portfolio segment and shows the contribution provided by both the recoveries and the provision along with the reduction of the allowance caused by charge-offs.

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 5 EARNINGS PER SHARE
	Basic earnings per share is calculated using the two-class method. The two-class method is an earnings allocation formula under which earnings per share is calculated from common stock and participating securities according to dividends declared and participation rights in undistributed earnings. Under this method, all earnings distributed and undistributed, are allocated to participating securities and common shares based on their respective rights to receive dividends. Unvested share-based payment awards that contain non-forfeitable rights to dividends are considered participating securities (i.e. unvested restricted stock), not subject to performance based measures. Basic earnings per share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding (inclusive of participating securities). Application of the two-class method for participating securities results a more dilutive basic earnings per share as the participating securities are allocated the same amount of income as if they are outstanding for purposes of basic earnings per share. There is no additional potential dilution in calculating diluted earnings per share, therefore basic and diluted earnings per share are the same amounts. Other than the restricted stock plan, the Company has no other stock based compensation plans.

Fair_Value_of_Instruments

Fair Value of Instruments	3 Months Ended
	Mar. 31, 2015
Fair Value Disclosures [Abstract]
Fair Value of Instruments	NOTE 6 FAIR VALUE OF INSTRUMENTS
	FAIR VALUE OF FINANCIAL INSTRUMENTS
	Fair values of financial instruments are management’s estimate of the values at which the instruments could be exchanged in a transaction between willing parties. These estimates are subjective and may vary significantly from amounts that would be realized in actual transactions. In addition, other significant assets are not considered financial assets including deferred tax assets, premises, equipment and intangibles. Further, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on the fair value estimates and have not been considered in any of the estimates.
	The following assumptions and methods were used in estimating the fair value for financial instruments.
	Cash and Cash Equivalents
	The carrying amounts reported in the balance sheet for cash, cash equivalents and federal funds sold approximate their fair values. Also included in this line item are the carrying amounts of interest-bearing deposits maturing within ninety days which approximate their fair values. Fair values of other interest-bearing deposits are estimated using discounted cash flow analyses based on current rates for similar types of deposits.
	Securities – Available-for-sale
	Fair values for securities, excluding Federal Home Loan Bank stock, are based on quoted market price, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments.
	Other Securities
	The carrying value of Federal Home Loan Bank stock, listed as “other securities”, approximates fair value based on the redemption provisions of the Federal Home Loan Bank.
	Loans, net
	For those variable-rate loans that re-price frequently, and with no significant change in credit risk, fair values are based on carrying values. The fair values of the fixed rate and all other loans are estimated using discounted cash flow analysis, using interest rates currently being offered for loans with similar terms to borrowers with similar credit quality.
	Deposits
	The fair values disclosed for deposits with no defined maturities are equal to their carrying amounts, which represent the amount payable on demand. The carrying amounts for variable-rate, fixed term money market accounts and certificates of deposit approximate their fair value at the reporting date. Fair value for fixed-rate certificates of deposit are estimated using a discounted cash flow analysis that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.
	Federal Funds Purchased and Securities Sold Under Agreement to Repurchase
	The carrying value of short-term borrowings approximates fair values.
	Accrued Interest Receivable and Payable
	The carrying amounts of accrued interest approximate their fair values.
	Dividends Payable
	The carrying amounts of dividends payable approximate their fair values and are generally paid within forty days of declaration.
	Off Balance Sheet Financial Instruments
	Fair values for off-balance sheet, credit related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counter-parties’ credit standing.
	The estimated fair values, and related carrying or notional amounts, for on and off-balance sheet financial instruments as of March 31, 2015 and December 31, 2014 are reflected below.

Fair Value Measurements
In general, fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities in active markets that the Company has the ability to access.
Available-for-sale securities, when quoted prices are available in an active market, securities are valued using the quoted price and are classified as Level 1.
Fair values determined by Level 2 inputs use other inputs that are observable, either directly or indirectly. These Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and other inputs such as interest rates and yield curves that are observable at commonly quoted intervals.
Available-for-sale securities classified as Level 2 are valued using the prices obtained from an independent pricing service. The prices are not adjusted. Securities of obligations of state and political subdivisions are valued using a type of matrix, or grid, pricing in which securities are benchmarked against the treasury rate based on credit rating. Substantially all assumptions used by the independent pricing service are observable in the marketplace, can be derived from observable data, or are supported by observable levels at which transactions are executed in the market place.
Level 3 inputs are unobservable inputs, including inputs that are available in situations where there is little, if any, market activity for the related asset or liability. The Bank holds some local municipals that the Bank evaluates based on the credit strength of the underlying project such as hospital or retirement housing. The fair value is determined by valuing similar credit payment streams at similar rates.
In instances where inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is significant to the valuation. The Company’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset.
The following summarizes financial assets measured at fair value on a recurring basis as of March 31, 2015 and December 31, 2014, segregated by level or the valuation inputs within the fair value hierarchy utilized to measure fair value:

Most of the Company’s available-for-sale securities, including any bonds issued by local municipalities, have CUSIP numbers or have similar characteristics of those in the municipal markets, making them marketable and comparable as Level 2.
The Company also has assets that, under certain conditions, are subject to measurement at fair value on a non-recurring basis. At March 31, 2015 and December 31, 2014, such assets consist primarily of impaired loans. Impaired loans categorized as Level 3 assets consist of non-homogeneous loans that are considered impaired. The Company estimates the fair value of the loans based on the present value of expected future cash flows using management’s best estimate of key assumptions. These assumptions include future payment ability, timing of payment streams, and estimated realizable values of available collateral (typically based on outside appraisals.)
At March 31, 2015 and December 31, 2014, impaired loans categorized as Level 3 were $1.8 and $1.5 million, respectively. The specific allocation for impaired loans was $428 and $387 thousand as of March 31, 2015 and December 31, 2014, respectively, which are accounted for in the allowance for loan losses (see Note 4).
Other real estate is reported at either the lower of the fair value of the real estate minus the estimated costs to sell the asset or the cost of the asset. The determination of fair value of the real estate relies primarily on appraisals from third parties. If the fair value of the real estate, minus the estimated costs to sell the asset, is less than the asset’s cost, the deficiency is recognized as a valuation allowance against the asset through a charge to expense. The valuation allowance is therefore increased or decreased, through charges or credits to expense, for changes in the asset’s fair value or estimated selling costs.

Cash and Cash Equivalents	Cash and Cash Equivalents
	The carrying amounts reported in the balance sheet for cash, cash equivalents and federal funds sold approximate their fair values. Also included in this line item are the carrying amounts of interest-bearing deposits maturing within ninety days which approximate their fair values. Fair values of other interest-bearing deposits are estimated using discounted cash flow analyses based on current rates for similar types of deposits.
Securities - Available-for-sale	Securities – Available-for-sale
	Fair values for securities, excluding Federal Home Loan Bank stock, are based on quoted market price, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments.
Other Securities	Other Securities
	The carrying value of Federal Home Loan Bank stock, listed as “other securities”, approximates fair value based on the redemption provisions of the Federal Home Loan Bank.
Loans, net	Loans, net
	For those variable-rate loans that re-price frequently, and with no significant change in credit risk, fair values are based on carrying values. The fair values of the fixed rate and all other loans are estimated using discounted cash flow analysis, using interest rates currently being offered for loans with similar terms to borrowers with similar credit quality.
Deposits	Deposits
	The fair values disclosed for deposits with no defined maturities are equal to their carrying amounts, which represent the amount payable on demand. The carrying amounts for variable-rate, fixed term money market accounts and certificates of deposit approximate their fair value at the reporting date. Fair value for fixed-rate certificates of deposit are estimated using a discounted cash flow analysis that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits.
