Basis of Presentation	'
	Note A - Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and the instructions to Form 10-Q and, accordingly, do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The December 31, 2013 condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2014, are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
	In preparing consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet and reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the evaluation of goodwill and other intangible assets for impairment, other-than-temporary impairment of securities and the valuation of deferred tax assets.

Impact of New Accounting Standards	'
	Note C - Impact of New Accounting Standards
	In July 2013, FASB issued ASU 2013-11, “Income Taxes Topic 740 – Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” The amendments in this ASU provide guidance for the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendments in this ASU are expected to reduce diversity in practice by providing guidance on the presentation of unrecognized tax benefits and will better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. The amendments apply to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date and are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this guidance did not have an impact on the Company’s results of operations or financial position.
	In January 2014, FASB issued ASU 2014-01, “Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects.” The amendments in this ASU apply to all reporting entities that invest in qualified affordable housing projects through limited liability entities that are flow-through entities for tax purposes as follows:
	1. For reporting entities that meet the conditions for and that elect to use the proportional amortization method to account for investments in qualified affordable housing projects, all amendments in this ASU apply.
	2. For reporting entities that do not meet the conditions for or that do not elect the proportional amortization method, only the amendments in this ASU that are related to disclosures apply.
	The amendments in this ASU permit reporting entities to make an accounting policy election 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 investment should be accounted for as an equity method investment or a cost method investment in accordance with Subtopic 970-323. The amendments in this ASU 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 public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.
	In January 2014, FASB issued ASU 2014-04, “Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.” The objective of the amendments in this ASU is to reduce diversity by clarifying when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. The amendments in this ASU 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 interim and annual 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 according to local requirements of the applicable jurisdiction. The amendments in this ASU are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.
	In April 2014, FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” This ASU changes the criteria for reporting discontinued operations and modifies related disclosure requirements. The new guidance is effective on a prospective basis for fiscal years beginning on or after December 15, 2014, and interim periods within those years. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

Fair Value Measurements	'
	Note D – Fair Value Measurements
	In accordance with ASC 820-10, “Fair Value Measurements and Disclosures,” the Company groups its financial assets and financial liabilities measured 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.
	Level 1 - Valuations for assets and liabilities traded in active exchange markets, such as The NASDAQ Stock Market. Level 1 also includes U.S. Treasury, other U.S. government and agency mortgage-backed securities that are traded by dealers or brokers in active markets. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.
	Level 2 - Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained from third party pricing services for identical or comparable assets or liabilities.
	Level 3 - Valuations for assets and liabilities that are derived from other methodologies, including option pricing models, discounted cash flow models and similar techniques, are not based on market exchange, dealer, or broker traded transactions. Level 3 valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets and liabilities.
	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.
	A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.
	The Company’s cash instruments are generally classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency.
	The Company’s investment in mortgage-backed securities, asset-backed securities, preferred stock with maturities and other debt securities available-for-sale are generally classified within Level 2 of the fair value hierarchy. For these securities, the Company obtains fair value measurements from independent pricing services. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. treasury yield curve, trading levels, market consensus prepayment speeds, credit information and the instrument’s terms and conditions.
	The Company’s derivative financial instruments are generally classified within Level 2 of the fair value hierarchy. For these financial instruments, the Company obtains fair value measurements from independent pricing services. The fair value measurements utilize a discounted cash flow model that incorporates and considers observable data that may include publicly available third party market quotes in developing the curve utilized for discounting future cash flows.
	Level 3 is for positions that are not traded in active markets or are subject to transfer restrictions, valuations are adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate is used. Subsequent to inception, management only changes Level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying investment or comparable entities, subsequent rounds of financing, recapitalization and other transactions across the capital structure, offerings in the equity or debt markets, and changes in financial ratios or cash flows.
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	Securities Available-for-Sale. The fair value of the Company’s available-for-sale securities portfolio is estimated using Level 1 and Level 2 inputs. The Company obtains fair value measurements from an independent pricing service. For Levels 1 and 2, the fair value measurements consider (i) quoted prices in active markets for identical assets and (ii) observable data that may include dealer quotes, market spreads, cash flows, market consensus prepayment speeds, credit information, and a bond’s terms and conditions, among other factors, respectively.
	Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
	Impaired Loans. Certain impaired loans are reported at the fair value of the underlying collateral if repayment is expected solely from collateral. Collateral values are estimated using Level 2 inputs based on appraisals of similar properties obtained from a third party valuation service. Fair values are estimated using Level 3 inputs based on appraisals of similar properties obtained from a third party valuation service discounted by management based on historical losses for similar collateral.
	Other Real Estate Owned. Other real estate owned is reported at the fair value of the underlying collateral less costs to sell. Collateral values are estimated using Level 3 inputs based on appraisals of similar properties obtained from a third party valuation service.
	The following summarizes assets and liabilities measured at fair value at March 31, 2014 and December 31, 2013.

	There were no loans measured for impairment using the fair value of the underlying collateral at March 31, 2014. Collateral dependent loans are valued using third party appraisals primarily using the sales comparison approach. The appraisals may be discounted between 25-40% to reflect realizable value based on historical losses which represents an unobservable input. Impaired loans measured for impairment, using the net present value of cash flows, had a recorded investment of $2.5 million with a valuation allowance of $182 thousand at March 31, 2014. Loans valued using the net present value of cash flows are calculated using expected future cash flows with a discount rate equal to the effective yield of the loan. At December 31, 2013, impaired loans had a recorded investment of $2.5 million with a valuation allowance of $197 thousand.
	The estimated fair values of the Company’s financial instruments at March 31, 2014, and December 31, 2013, all of which are held or issued for purposes other than trading, were as follows:

Credit Quality Information
The Company utilizes a nine grade internal loan rating system for commercial real estate, construction and commercial loans as follows:
	•		Loans rated 10-35: Loans in these categories are considered “pass” rated loans with low to average risk.
	•		Loans rated 40: Loans in this category are considered “special mention.” These loans are starting to show signs of potential weakness and are being closely monitored by management.
	•		Loans rated 50: Loans in this category are considered “substandard.” Generally, a loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. There is a distinct possibility that the Company will sustain some loss if the weakness is not corrected.
	•		Loans rated 60: Loans in this category are considered “doubtful.” Loans classified as doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable.
	•		Loans rated 70: Loans in this category are considered uncollectible or a loss, and of such little value that their continuance as loans is not warranted.
On an annual basis, or more often if needed, the Company formally reviews the ratings on all commercial real estate, construction and commercial loans over $250 thousand. The assessment of those loans less than $250 thousand are based on the borrower’s ability to pay and not on overall risk. Additionally, the Company monitors the repayment activity for loans less than $250 thousand and if a loan becomes delinquent over 60 days past due, it is reviewed for risk and is subsequently risk rated based on available information such as ability to repay based on current cash flow conditions and workout discussions with the borrower.
Loan Servicing
The Company recognizes as separate assets from their related loans the rights to service mortgage loans for others, either through acquisition of those rights or from the sale or securitization of loans with the servicing rights retained on those loans, based on their relative fair values. To determine the fair value of the servicing rights created, the Company uses the market prices under comparable servicing sale contracts, when available, or alternatively uses a valuation model that calculates the present value of future cash flows to determine the fair value of the servicing rights. In using this valuation method, the Company incorporates assumptions that market participants would use in estimating future net servicing income, which includes estimates of the cost of servicing loans, the discount rate, ancillary income, prepayment speeds and default rates.
Mortgage servicing rights are amortized in proportion to, and over the period of, estimated net servicing revenues. Refinance activities are considered in estimating the period of net servicing revenues. Impairment of mortgage servicing rights is assessed based on the fair value of those rights. Fair values are estimated using discounted cash flows based on a current market interest rate. For purposes of measuring impairment, the rights are stratified based on the interest rate risk characteristics of the underlying loans. The amount of impairment recognized is the amount by which the capitalized mortgage servicing rights for a stratum exceed their fair value.
The balance of capitalized servicing rights, net of valuation allowances, included in other assets at March 31, 2014, was $2.6 million. The fair value of capitalized servicing rights was $4.3 million as of March 31, 2014. Servicing rights of $49 thousand were capitalized during the three months ended March 31, 2014, compared to $57 thousand for the same period in 2013. Amortization of capitalized servicing rights was $152 thousand for the three months ended March 31, 2014, compared to $246 thousand for the same period in 2013.
Following is an analysis of the aggregate changes in the valuation allowance for capitalized servicing rights during the periods indicated:

Income Taxes	'
	In July 2013, FASB issued ASU 2013-11, “Income Taxes Topic 740 – Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” The amendments in this ASU provide guidance for the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendments in this ASU are expected to reduce diversity in practice by providing guidance on the presentation of unrecognized tax benefits and will better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. The amendments apply to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date and are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this guidance did not have an impact on the Company’s results of operations or financial position.
Investments	'
	In January 2014, FASB issued ASU 2014-01, “Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects.” The amendments in this ASU apply to all reporting entities that invest in qualified affordable housing projects through limited liability entities that are flow-through entities for tax purposes as follows:
	1. For reporting entities that meet the conditions for and that elect to use the proportional amortization method to account for investments in qualified affordable housing projects, all amendments in this ASU apply.
	2. For reporting entities that do not meet the conditions for or that do not elect the proportional amortization method, only the amendments in this ASU that are related to disclosures apply.
	The amendments in this ASU permit reporting entities to make an accounting policy election 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 investment should be accounted for as an equity method investment or a cost method investment in accordance with Subtopic 970-323. The amendments in this ASU 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 public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.
Receivables	'
	In January 2014, FASB issued ASU 2014-04, “Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.” The objective of the amendments in this ASU is to reduce diversity by clarifying when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. The amendments in this ASU 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 interim and annual 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 according to local requirements of the applicable jurisdiction. The amendments in this ASU are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.
Presentation of Financial Statements and Property, Plant and Equipment	'
	In April 2014, FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” This ASU changes the criteria for reporting discontinued operations and modifies related disclosure requirements. The new guidance is effective on a prospective basis for fiscal years beginning on or after December 15, 2014, and interim periods within those years. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.
