Use of Estimates	'
	NOTE 3 — Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan and lease losses and the valuation of property that is included in “other real estate owned” on our consolidated balance sheet and that was acquired in connection with foreclosures or in satisfaction of loans. In connection with the determination of the allowances for loan and lease losses and valuation of other real estate owned, management obtains independent appraisals for significant properties.

Investments Debt And Equity Securities [Abstract]	'
Investment Securities	'
	NOTE 6 — Investment Securities
	Investments in securities are classified in two categories and accounted for as follows:
	Securities Held-to-Maturity – Bonds, notes, debentures and mortgage-backed securities for which the Company has the positive intent and ability to hold to maturity are reported at cost, adjusted for amortization of premiums and accretion of discounts computed on the straight-line basis, which approximates the interest method, over the remaining period to maturity.
	Securities Available-for-Sale – Bonds, notes, debentures, mortgage-backed securities not classified as securities to be held to maturity and certain equity securities are classified as available-for-sale and carried at fair value with unrealized holding gains and losses, net of tax, reported as a net amount in a separate component of stockholders’ equity until realized.
	The amortization of premiums on mortgage-backed securities is done based on management’s estimate of the lives of the securities, adjusted, when necessary, for advanced prepayments in excess of those estimates.
	Realized gains and losses on the sale of securities available-for-sale are determined using the specific identification method and are reported as a separate component of other income in the Statements of Income. Unrealized gains and losses are included as a separate item in computing comprehensive income.
	Investment securities are evaluated periodically to determine whether a decline in their value is other than temporary. Management utilizes criteria such as the magnitude and duration of the decline, in addition to the reasons underlying the decline, to determine whether the loss in value is other than temporary. The term “other than temporary” is not intended to indicate that the decline is permanent. It indicates that the prospects for a near term recovery of value are not necessarily favorable, or that there is a lack of evidence to support fair values equal to, or greater than, the carrying value of the security. Once a decline in value is determined to be other than temporary, the value of the security is reduced and a corresponding charge to earnings is recognized.
	The amortized cost and fair value of investment securities at September 30, 2013 and December 31, 2012 are as follows:

	The amortized cost and fair value of debt securities at September 30, 2013 by contractual maturity are shown in the following table.

At September 30, 2013, twenty-three securities had unrealized losses for less than twelve months and one security had been in an unrealized loss position for twelve or more months. At December 31, 2012, four securities had unrealized losses for less than twelve months and one security had been in an unrealized loss position for twelve or more months.
U.S. Agency Securities
The unrealized losses on the Company’s investments in U.S. Agency securities were caused by interest rate fluctuations and not credit quality. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the par value of the investment. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at September 30, 2013.
States and Political Subdivisions
The unrealized losses on the Company’s investments in states and political subdivisions were caused by interest rate fluctuations and not credit quality. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the par value of the investment. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired at September 30, 2013.
Marketable Equity Securities
The unrealized losses on the Company’s investments in marketable equity securities were caused by interest rate fluctuations and general market conditions. The Company’s investments in marketable equity securities consist primarily of investments in common stock of companies in the financial services industry. The Company has analyzed its equity portfolio and determined that the market value fluctuation in these equity securities is not a cause for recognition of a current loss. Because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their cost bases, the Company does not consider those investments to be other-than-temporarily impaired at September 30, 2013.

Credit Quality Indicators. As part of the on-going monitoring of the credit quality of the Bank’s loan portfolio, management tracks certain credit quality indicators including trends related to loan delinquency, the level of classified commercial loans, net charge-offs, non-performing loans and the general economic conditions in the Company’s market area.
The Bank utilizes a risk grading matrix to assign a risk grade to each of its commercial loans. Loans are graded on a scale of 1 to 8. A description of the general characteristics of the 8 risk grades is as follows:
Pass 1 (Minimal Risk—Cash equivalent or exceptional credit)
This classification includes loans which are fully secured by liquid collateral. Examples include: deposits, life insurance, certificates of deposit and securities.
The borrower demonstrates exceptional credit fundamentals, including stable and predictable profit margins and cash flows, strong liquidity and a conservative balance sheet with superior asset quality. Excellent cash flow coverage of existing and projected debt service. Historic and projected performance indicates borrower is able to meet obligations under almost any economic circumstances. The company has very good, professional management with an excellent track record and good depth in successor management.
Pass 2 (Average Risk)
This classification includes all loans which have no identifiable risk of collection and conform in all aspects to the Bank’s policies and procedures as well as federal and state regulations. Documentation exceptions must be minimal and in the process of correction and not of a type that could subsequently introduce loan loss risk.
Borrower generates sufficient cash flow to fund debt service and some working assets and/or capital expansion needs. Profitability and key balance sheet ratios are at or slightly above peers. Current trends are positive or stable. Earnings are level or above the last two years.
Management has average to good experience with similar business activities and markets. The present venture appears to be well within management’s capacity. Management has depth, less formal but acceptable succession plan and limited turnover in key positions.
The industry is relatively established and the borrower is well established within the industry. Over-capacity and competitive forces are consistent with normal business cycles.
Pass 3 (Acceptable Risk)
This classification includes loans with terms and conditions that may deviate from the Bank’s loan policy. Collateral marketability and margins may exceed policy. Significant administration may be required.
Borrower generates sufficient cash flow to fund debt service, but most working asset and all capital expansion needs are provided from external sources. Borrower is able to meet payments. Profitability ratios and key balance sheet ratios are usually close to peers but one or more ratios e.g. leverage may be higher than peer. Earnings may be trending down over the last three years. Borrower may be able to obtain similar financing from other banks with comparable or less favorable terms.
Some management weakness may be evident, primarily in lack of depth. Management may come from unrelated industries or have more limited but acceptable experience. Key management succession may not be clear.
Borrower generally has limited capacity for additional debt. The Borrower has modest but sufficient debt coverage. Loans are protected by collateral. Business may be adversely affected by deteriorating industry conditions, internal operations problems, pending litigation or declining collateral quality. Potential adverse conditions are manageable.
Industry may be transitional or historically volatile or may be trending down. Long-term outlook is acceptable. Firm may be established but not quite as strong or large as the average firm in the industry, or firm may be new in the industry.
Pass 4 (Watch)
This category can cover many different situations. A typical watch situation is one where a strong or moderately strong borrower suffers business reversals which are not long term but require attention.
The borrower has weaknesses resulting from performance trends or management concerns. The financial condition of the company has taken a negative turn and may be temporarily strained. Borrowers may exhibit excessive growth, declining earnings, strained cash flow, increasing leverage and/or weakening market position that indicate above average risk. Interim losses and/or adverse trends may occur, but not to the level that would affect the Bank’s position. Cash flow may be weak but minimally acceptable.
Loans rated 4 are not considered criticized or classified assets. The rating is effective until the credit is strengthened or the relationship is moved out of the Bank. Therefore, the category does not include loans with undue or unwarranted credit risks that constitute identifiable weaknesses.
Criticized – Other Assets Especially Mentioned (Rated 5)
A “Criticized” (OAEM) classification includes loans which are fundamentally sound, but exhibit potential weaknesses which require corrective action to avoid any future credit risk. Close monitoring by the loan officer is warranted. Assets with this classification do not expose the Bank to sufficient risk to justify an adverse classification.
The following criteria are representative of a Criticized grade:
	•		An inadequate loan agreement or an inability to obtain the necessary loan documents or financial statements.
	•		Loans for which the loan agreement terms or covenants have been violated or waived.
	•		Adverse economic and market conditions which, in the future, may affect the borrower’s repayment ability.
	•		An adverse trend in the borrower’s financial condition that has not yet reached the point where the original payment terms are jeopardized.
	•		A payment schedule which delays principal amortization.
	•		Loans with collateral values where there is little margin between liquidation value and the amount of the loan commitment, or where the collateral has shown evidence of deterioration.
	•		Loan officers must work closely with the borrower and explore alternate means to diminish risk. Loans classified OAEM should be considered candidates for management by the Asset Recovery Officer.
Classified – Substandard (Rated 6)
Classified assets include loans with well-defined weaknesses which are inadequately protected by current net worth, repayment capacity, or pledged collateral of the borrower. Loans are classified when they have one or more weaknesses that could jeopardize debt repayment and/or liquidation, primarily resulting in the possibility that the Bank may sustain some loss if the deficiencies are not corrected.
A substandard loan may exhibit one or more of the following conditions:
	•		Borrower is unable to generate enough cash flow for debt reduction.
	•		Primary source of repayment is impaired or no longer available, and the Bank is relying upon the secondary source.
	•		Loss does not seem likely, but sufficient problems have arisen to cause the Bank to go to abnormal lengths to protect its position in order to maintain a high probability of repayment.
	•		Deterioration in the condition of the collateral or inadequate inspection or verification of value.
	•		Documentation flaws leaving the Bank in a subordinated or unsecured position.
	•		All substandard loans should be managed by the Asset Recovery Officer.
Doubtful (Rated 7)
An asset classified as Doubtful has all weaknesses inherent in the substandard category where collection or liquidation in full is highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors that 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. Pending factors include proposed merger, acquisition, liquidation proceedings, capital injection, perfecting liens on additional collateral, and business restructure plans.
The Bank considers Doubtful to be a temporary classification and will only classify an asset, or portion of an asset, as such when the information is not available to conclude as to classification or more clearly define the potential for loss. All loans classified as Doubtful are placed on non-accrual status and assigned to the Asset Recovery Officer for supervision.
Loss (Rated 8)
An asset classified as Loss is considered uncollectible and of such little value that its continuance as a bankable asset is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future. All losses should be recognized in the quarter in which they are identified. These loans are to be managed by the Asset Recovery Officer.

Impaired Loans. Loans are considered impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. If a loan is impaired, a specific valuation allowance is allocated, if necessary, so that the loan is reported net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions thereof, are charged off when deemed uncollectible.

Non-Accrual and Past Due Loans. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on non-accrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. Loans may be placed on non-accrual status regardless of whether or not such loans are considered past due. When interest accrual is discontinued, all unpaid accrued interest income is reversed. Interest income is subsequently recognized only to the extent cash payments are received in excess of principal due. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured with at least a six month positive payment history.
Period-end non-accrual loans, segregated by class of loans, were as follows:

The loan classified as a Troubled Debt Restructuring (TDR), was charged down during 2010 to a balance of $401 and the entire pre-modification balance was split into two notes. The customer is currently paying principal and interest on one note and interest only on the other note. Nonetheless, the loan is fully reserved based on management’s evaluation of both the customer’s ability to maintain its cash flow and the value of the underlying collateral.

Loan Servicing	'
	NOTE 8 — Loan Servicing
	The Company generally retains the right to service mortgage loans sold to others. The cost allocated to the mortgage servicing rights retained has been recognized as a separate asset within other assets and is being amortized in proportion to and over the period of estimated net servicing income.
	Mortgage servicing rights are evaluated for impairment based on the fair value of those rights. Fair values are estimated using discounted cash flows based on current market rates of interest and expected future prepayment rates. For purposes of measuring impairment, the rights must be stratified by one or more predominant risk characteristics of the underlying loans. The Company stratifies its capitalized mortgage servicing rights based on the product type, interest rate and term of the underlying loans. The amount of impairment recognized is the amount, if any, by which the amortized cost of the rights for each stratum, exceed the fair value.

Goodwill	'
	NOTE 9 — Goodwill
	Goodwill represents the excess of the purchase price over the underlying fair value of merged entities. Goodwill is assessed for impairment at least annually and as triggering events occur. In making this assessment, management considers a number of factors including, but not limited to, operating results, business plans, economic projections, anticipated future cash flows, and current market data. There are inherent uncertainties related to these factors and management’s judgment in applying them to the analysis of goodwill impairment. Changes in economic and operating conditions, as well as other factors, could result in goodwill impairment in future periods.

	Note 15 — Fair Value Measurements
	The following table sets forth the Company’s financial assets that were accounted for at fair value and are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.
	Level I-Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
	Level II-Observable inputs other than Level I prices, such as quoted prices for similar assets or liabilities in active markets; quoted prices in markets that are not active for identical or similar assets or liabilities; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level III-Unobservable inputs that are supported by little or no market activity and significant to the fair value of the assets or liabilities that are developed using the reporting entities’ estimates and assumptions, which reflect those that market participants would use.
	Assets Measured at Fair Value on a Recurring Basis
	A description of the valuation methodologies used for financial assets measured at fair value on a recurring basis, as well as the classification of the assets pursuant to the valuation hierarchy, are as follows:
	Securities Available-for-Sale
	Securities classified as available-for-sale are reported using Level I, Level II and Level III inputs. Level I instruments generally include equity securities valued in accordance with quoted market prices in active markets. Level II instruments include U.S. government agency obligations, state and municipal bonds, mortgage-backed securities and corporate bonds. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Level III instruments include certain non-public equity securities and real estate sold under contract. The Company did not hold any instruments measured at fair value on a recurring basis using Level III inputs as of September 30, 2013. See Note 3 – Investment Securities for additional information.
	Assets measured at fair value on a recurring basis are summarized as follows:

	Assets Measured at Fair Value on a Nonrecurring Basis
	Certain non-financial assets and non-financial liabilities, measured at fair value on a non-recurring basis, include foreclosed and non-performing assets, goodwill and intangible assets.
	A description of the valuation methodologies and classification levels used for non-financial assets and non-financial liabilities measured at fair value on a nonrecurring basis are listed as follows:
	Goodwill and Other Identifiable Intangibles
	The Company employs general industry practices in evaluating the fair value of its goodwill and other identifiable intangibles. The Company calculates the fair value, with the assistance of a third party valuation firm, using a combination of the following valuation methods: dividend discount analysis under the income approach, which calculates the present value of all excess cash flows plus the present value of a terminal value and market multiples (pricing ratios) under the market approach. Management performed a review of goodwill and other identifiable intangibles as of December 31, 2012. Goodwill and other identifiable intangibles were not evaluated during the nine months ended September 30, 2013 as a result of management’s determination that no evidence of impairment was present during the period.
	Impaired Loans
	At September 30, 2013 certain impaired loans were re-measured and reported at fair value through a specific valuation allowance allocation of the allowance for loan and lease losses based upon the fair value of the underlying collateral and the evaluation of expected future cash flows. Impaired loans with a carrying value of $6,379 were reduced by a specific valuation allowance allocation totaling $1,959, to a total reported fair value of $4,420 based on collateral valuations utilizing Level III valuation inputs.
	Federal Home Loan Bank Stock
	Federal Home Loan Bank of Pittsburgh (FHLB) stock is a required investment in order for the Company to participate in a FHLB line of credit program. The FHLB stock is stated at par value as it is restricted to purchases and sales with the FHLB.
	Other Real Estate Owned
	Foreclosed real estate, which is considered to be a non-financial asset, has been valued using a market approach. The values were determined using market prices of similar real estate assets, which the Company considered to be Level II inputs.
	Preferred Stock
	Preferred stock consists of an investment in Senior Housing Crime Prevention Foundation Investment Corporation, an entity which supports Community Reinvestment Act initiatives.
	Certain assets measured at fair value on a non-recurring basis as of September 30, 2013 are as follows:

Disclosures about Fair Value of Financial Instruments
GAAP requires disclosure of the estimated fair value of an entity’s assets and liabilities considered to be financial instruments. As with most financial institutions, the majority of the Company’s assets and liabilities are considered financial instruments. However, many such instruments lack an available trading market, as characterized by a willing buyer and seller engaging in an exchange transaction. It is the Company’s general practice and intent to hold its financial instruments to maturity and not to engage in trading or sales activities, except for certain loans and investments. Therefore, the Company had to use significant estimates and present value calculations to prepare this disclosure.
Changes in the assumptions or methodologies used to estimate fair values may materially affect the estimated amounts. Also, management is concerned that there may not be reasonable comparability between institutions due to the wide range of permitted assumptions and methodologies in the absence of active markets. This lack of uniformity gives rise to a high degree of subjectivity in estimating financial instrument fair values.
Estimated fair values have been determined by the Company using the best available data and an estimation methodology suitable for each category of financial instruments. The estimation methodologies used at September 30, 2013 and December 31, 2012 are outlined below. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or non-recurring basis are discussed in the fair value measurements section above. The estimated fair value approximates carrying value for cash and cash equivalents, accrued interest and the bank-owned life insurance policies. The methodologies for other financial assets and financial liabilities are discussed below:
Short-term financial instruments
The carrying value of short-term financial instruments including cash and due from banks, federal funds sold, interest-bearing deposits in banks and other short-term investments and borrowings, approximates the fair value of these instruments. These financial instruments generally expose the Company to limited credit risk and have no stated maturities or have short-term maturities with interest rates that approximate market rates.
Investment securities held-to-maturity
The estimated fair values of investment securities held to maturity are based on quoted market prices provided by independent third parties that specialize in those investment sectors. If quoted market prices are not available, estimated fair values are based on quoted market prices of comparable instruments.
Loans
The loan portfolio, net of unearned income, has been valued by a third party valuation firm using quoted market prices, if available. When market prices were not available, a credit risk-based discounted cash flow analysis was utilized. The primary assumptions utilized in this analysis are the discount rate based on the LIBOR curve, adjusted for credit risk, and prepayment estimates based on factors such as refinancing incentives, age of the loan and seasonality. These assumptions were applied by loan category and different spreads were applied based upon prevailing market rates by category.
Deposits
The estimated fair values of demand deposits (interest and non-interest bearing checking accounts, savings and money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (their carrying amounts). The fair value for certificates of deposit was calculated by an independent third party by discounting contractual cash flows using current market rates for instruments with similar maturities, using a credit based risk model. The carrying amount of accrued interest receivable and payable approximates fair value.
Long-term borrowings
The amounts assigned to long-term borrowings were based on quoted market prices, when available, or based on discounted cash flow calculations using prevailing market interest rates for debt of similar terms.
The carrying and fair values of certain financial instruments are as follows:

Regulatory Matters	'
	NOTE 16 — Regulatory Matters
	The Company and the Bank are subject to various regulatory capital requirements administered by the Federal Deposit Insurance Corporation (FDIC) and the Board of Governors of the Federal Reserve System (Federal Reserve Board). Failure to meet minimum capital requirements can initiate certain mandatory–and possibly additional discretionary–actions by regulators that, if undertaken, could have a direct material effect on the Company and the Bank’s Consolidated Financial Statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Company and 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 Company and the Bank to maintain minimum amounts and ratios (set forth in the following Capital Adequacy table) of Tier I and Total Capital to risk-weighted assets and of Tier I Capital to average assets (Leverage ratio). The table also presents the Company’s actual capital amounts and ratios. Management believes, as of September 30, 2013, that the Company and the Bank meet all capital adequacy requirements to which they are subject.
	As of September 30, 2013, the most recent regulatory notifications categorized the Bank as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized”, the Bank must maintain minimum Tier I Capital, Total Capital and Leverage ratios as set forth in the Capital Adequacy table. There are no conditions or events since that notification that management believes have changed the Company’s categorization by the FDIC.
	The Company and Bank are also subject to minimum capital levels, which could limit the payment of dividends. As of September 30, 2013, the Company and Bank had capital levels that were in excess of the minimum capital level ratios required to pay dividends.
	The Pennsylvania Banking Code restricts capital funds available for payment of dividends to the retained earnings of the Bank. The balances in the capital stock and surplus accounts are unavailable for dividends. Dividends from the Bank are the Company’s primary source of funds.
	In addition, the Bank is subject to restrictions imposed by Federal law on certain transactions with the Company’s affiliates. These transactions include extensions of credit, purchases of or investments in stock issued by an affiliate, purchases of assets subject to certain exceptions, acceptance of securities issued by an affiliate as collateral for loans, and the issuance of guarantees, acceptances, and letters of credit on behalf of affiliates. These restrictions prevent the Company’s affiliates from borrowing from the Bank unless the loans are secured by obligations of designated amounts. Further, the aggregate value of such transactions between the Bank and a single affiliate is limited in amount to 10 percent of the Bank’s capital stock and surplus, and the aggregate value of such transactions with all affiliates is limited to 20 percent of the Bank’s capital stock and surplus. The Federal Reserve System has interpreted “capital stock and surplus” to include undivided profits.

Postemployment Benefits [Abstract]	'
Post-retirement Life Insurance Benefit	'
	Note 17 — Post-retirement Life Insurance Benefit
	In 1995, the Company established a post-retirement life insurance benefit equal to three times the employees’ salary at retirement for all employees employed with the Company at July 1, 1995. Employees hired by the Company after July 1, 1995, received a post-retirement life insurance benefit equal to $50,000 at retirement, which decreases by $5,000 annually to a minimum benefit of $5,000 by the time the recipient reaches age 75. In June of 2012, the Company amended the post-retirement life insurance benefit for all active employees, regardless of hire date, to a benefit of $50,000 at retirement, then decreasing by $5,000 a year to $5,000 at age 75. Because the product offered is term life insurance, the Company is exposed to increasing costs in future years.
	The Company is evaluating various options to reduce or settle its obligation for benefits, to the current retiree group only. One option under consideration is a plan offered by an insurance company, as to this current retiree group, whereby the Company would enter into an agreement with the insurance company to transfer all risk and obligation for the benefits payable as to the current retiree group in exchange for a one-time fixed payment by the Company.
	The agreement would require a one-time payment to the insurance company, estimated to be approximately $2.5 million. There would be no further cost to the Company as to the current retirees, after this payment. The Company would recognize a settlement charge, net of tax, of approximately $1.1 million in the period in which it occurs.
