Impact of New Accounting Standards	'
	Note C – Impact of New Accounting Standards
	In December 2011, FASB issued Accounting Standards Update (“ASU”) 2011-11, “Disclosures about Offsetting Assets and Liabilities.” This ASU is to enhance current disclosures. Entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The amendments in this ASU are effective for annual periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures required by those amendments retrospectively for all comparative periods presented. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.
	In October 2012, FASB issued ASU 2012-06, “Business Combinations (Topic 805): Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution.” The amendments in this update clarify the applicable guidance for subsequently measuring an indemnification asset recognized as a result of a government-assisted acquisition of a financial institution. The amendments in this update are effective for fiscal years, and interim periods within those years beginning on or after December 15, 2012. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.
	In February 2013, FASB issued ASU 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” The amendments in this update do not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The amendments are effective prospectively for reporting periods beginning after December 15, 2012. Early adoption is permitted. The required disclosures have been reflected in the accompanying footnotes to the condensed consolidated financial statements.
	In February 2013, FASB issued ASU 2013-04, “Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date.” The objective of the amendments in this update is to provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. Examples of obligations within the scope of this update include debt arrangements, other contractual obligations, and settled litigation and judicial rulings. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, and should be applied retrospectively to all prior periods presented for those obligations resulting from joint and several liability arrangements within the scope of this update that exist at the beginning of an entity’s fiscal year of adoption. The Company anticipates that the adoption of this guidance will not have a material impact on its consolidated financial statements.
	In April 2013, FASB issued ASU 2013-07, “Presentation of Financial Statements (Topic 205): Liquidation Basis of Accounting.” The amendments in this update are being issued to clarify when an entity should apply the liquidation basis of accounting. The guidance provides principles for the recognition and measurement of assets and liabilities and requirements for financial statements prepared using the liquidation basis of accounting. Additionally, the amendments require disclosures about an entity’s plan for liquidation, the methods and significant assumptions used to measure assets and liabilities, the type and amount of costs and income accrued, and the expected duration of the liquidation process. The amendments are effective for entities that determine liquidation is imminent during annual reporting periods beginning after December 15, 2013, and interim reporting periods therein. Entities should apply the requirements prospectively from the day that liquidation becomes imminent. Early adoption is permitted. The Company anticipates that the adoption of this guidance will not have an impact on its consolidated financial statements.
	In July 2013, FASB issued ASU 2013-10, “Derivatives and Hedging (Topic 815) - Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes.” The amendments in this ASU permit the Fed Funds Effective Swap Rate (OIS) to be used as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815, in addition to Treasury Obligations of the U.S. government (UST) and the London Interbank Offered Rate (LIBOR). The amendments also remove the restriction on using different benchmark rates for similar hedges. The amendments apply to all entities that elect to apply hedge accounting of the benchmark interest rate under Topic 815. The amendments are effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The Company anticipates that the adoption of this guidance will not have a material impact on its results of operations or financial position.
	In July 2013, FASB issued ASU 2013-11, “Income Taxes - 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 update 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 update 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 Company anticipates that the adoption of this guidance will not have a material impact on its results of operations or financial position.

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. 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 September 30, 2013, and December 31, 2012.

There were no impaired loans measured for impairment, using the fair value of the collateral for collateral dependent loans, at September 30, 2013. 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 $3.1 million with a valuation allowance of $381 thousand at September 30, 2013. 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, 2012, impaired loans had a recorded investment of $1.7 million with a valuation allowance of $361 thousand. Changes in fair value recognized for partial charge-offs of loans and impairment reserves on loans was a net decrease of $1.4 million and $2.0 million for the nine months ended September 30, 2013 and 2012, respectively.
The estimated fair values of the Company’s financial instruments at September 30, 2013, and December 31, 2012, all of which are held or issued for purposes other than trading, were as follows:

Loans are considered to be in payment default once it is greater than 30 days contractually past due under the modified terms. The troubled debt restructurings described above that subsequently defaulted resulted in no additional allocation of the allowance for credit losses for the nine month period ending September 30, 2013. There were two charge-offs totaling $46 thousand on these defaulted troubled debt restructurings during the nine month period ending September 30, 2013.

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 September 30, 2013, was $2.6 million. The fair value of capitalized servicing rights was $3.8 million as of September 30, 2013. Servicing rights of $1.3 million were capitalized during the nine months ended September 30, 2013, compared to $745 thousand for the same period in 2012. Amortization of capitalized servicing rights was $720 thousand for the nine months ended September 30, 2013, compared to $763 thousand for the same period in 2012. Servicing rights of $290 thousand were capitalized during the three months ended September 30, 2013, compared to $306 thousand for the same period in 2012. Amortization of capitalized servicing rights was $235 thousand for the three months ended September 30, 2013, compared to $264 thousand for the same period in 2012.

Impact_of_New_Accounting_Stand1

Impact of New Accounting Standards (Policies)	9 Months Ended
	Sep. 30, 2013
Disclosures about Offsetting Assets and Liabilities	'
	In December 2011, FASB issued Accounting Standards Update (“ASU”) 2011-11, “Disclosures about Offsetting Assets and Liabilities.” This ASU is to enhance current disclosures. Entities are required to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The amendments in this ASU are effective for annual periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures required by those amendments retrospectively for all comparative periods presented. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.
Business Combinations	'
	In October 2012, FASB issued ASU 2012-06, “Business Combinations (Topic 805): Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution.” The amendments in this update clarify the applicable guidance for subsequently measuring an indemnification asset recognized as a result of a government-assisted acquisition of a financial institution. The amendments in this update are effective for fiscal years, and interim periods within those years beginning on or after December 15, 2012. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.
Comprehensive Income	'
	In February 2013, FASB issued ASU 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” The amendments in this update do not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The amendments are effective prospectively for reporting periods beginning after December 15, 2012. Early adoption is permitted. The required disclosures have been reflected in the accompanying footnotes to the condensed consolidated financial statements.
Liabilities	'
	In February 2013, FASB issued ASU 2013-04, “Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date.” The objective of the amendments in this update is to provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. Examples of obligations within the scope of this update include debt arrangements, other contractual obligations, and settled litigation and judicial rulings. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, and should be applied retrospectively to all prior periods presented for those obligations resulting from joint and several liability arrangements within the scope of this update that exist at the beginning of an entity’s fiscal year of adoption. The Company anticipates that the adoption of this guidance will not have a material impact on its consolidated financial statements.
Presentation of Financial Statements	'
	In April 2013, FASB issued ASU 2013-07, “Presentation of Financial Statements (Topic 205): Liquidation Basis of Accounting.” The amendments in this update are being issued to clarify when an entity should apply the liquidation basis of accounting. The guidance provides principles for the recognition and measurement of assets and liabilities and requirements for financial statements prepared using the liquidation basis of accounting. Additionally, the amendments require disclosures about an entity’s plan for liquidation, the methods and significant assumptions used to measure assets and liabilities, the type and amount of costs and income accrued, and the expected duration of the liquidation process. The amendments are effective for entities that determine liquidation is imminent during annual reporting periods beginning after December 15, 2013, and interim reporting periods therein. Entities should apply the requirements prospectively from the day that liquidation becomes imminent. Early adoption is permitted. The Company anticipates that the adoption of this guidance will not have an impact on its consolidated financial statements.
Derivatives and Hedging	'
	In July 2013, FASB issued ASU 2013-10, “Derivatives and Hedging (Topic 815) - Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes.” The amendments in this ASU permit the Fed Funds Effective Swap Rate (OIS) to be used as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815, in addition to Treasury Obligations of the U.S. government (UST) and the London Interbank Offered Rate (LIBOR). The amendments also remove the restriction on using different benchmark rates for similar hedges. The amendments apply to all entities that elect to apply hedge accounting of the benchmark interest rate under Topic 815. The amendments are effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The Company anticipates that the adoption of this guidance will not have a material impact on its results of operations or financial position.
Income Taxes	'
	In July 2013, FASB issued ASU 2013-11, “Income Taxes - 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 update 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 update 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 Company anticipates that the adoption of this guidance will not have a material impact on its results of operations or financial position.
