	At June 30, 2014, of the 392 investment securities held, there were 81 in unrealized loss positions. Unrealized losses existed on certain securities classified as obligations of U.S. government agencies, obligations of state and political subdivisions, private-label mortgage-backed securities, mortgage-backed securities and SBA variable rate pools. The unrealized losses on mortgage-backed securities and securities that are obligations of U.S. government agencies were deemed to be temporary, as these securities retain strong credit ratings, continue to perform adequately, and are backed by various government-sponsored enterprises. These decreases in fair value are associated with the changes in market interest rates or the widening of market spreads subsequent to the initial purchase of the securities, and are not due to concerns regarding the underlying credit of the issuers or the underlying collateral. The decline in value of these securities has resulted from current economic conditions. Although yields on these securities may be below market rates during the period, no loss of principal is expected.
	The following table presents a summary of securities in a continuous unrealized loss position at June 30, 2014:
		Securities in		Gross		Securities in			Gross
		Continuous		Unrealized Loss		Continuous			Unrealized Loss

	During the second quarter 2014, management reviewed all private label mortgage backed securities for the presence of other-than-temporary impairment (“OTTI”). During this review, it was determined that other-than-temporary impairment existed on one classified private-label mortgage-backed security. After further analysis, it was also determined that future impairment was possible, based on the performance of the security. Instead of recording OTTI, management sold the security at a loss during second quarter 2014 to limit potential future losses. Therefore, no additional OTTI was booked during the period ended June 30, 2014.
	Management’s OTTI evaluation included the use of independently generated third-party credit surveillance reports that analyze the loans underlying each security. These reports include estimates of default rates and severities, life collateral loss rates, and static voluntary prepayment assumptions to generate estimated cash flows at the individual security level. Additionally, management considered factors such as downgraded credit ratings, severity and duration of the impairments, the stability of the issuers, and any discounts paid when the securities were purchased. Management has considered all available information related to the collectability of the impaired investment securities and believes that the estimated credit loss is appropriate.
	Following is a tabular roll-forward of the amount of credit-related OTTI recognized in earnings during the three and six months ended June 30, 2014, and 2013:
		Three months ended				Six months ended

	At June 30, 2014, six of the Company’s private-label mortgage-backed securities with an amortized cost of $2,050 were classified as substandard as their underlying credit was considered impaired. Securities with an amortized cost of $2,593 and $2,858 were classified as substandard at December 31, 2013, and June 30, 2013, respectively.
	At June 30, 2014, the projected average life of the securities portfolio was 4.24 years.
	The amortized cost and estimated fair values of securities available-for-sale at December 31, 2013, were as follows:

Loans, Allowance for Loan Losses, and Credit Quality Indicators	'
	NOTE 3 – LOANS, ALLOWANCE FOR LOAN LOSSES, AND CREDIT QUALITY INDICATORS
	Loans are stated at the amount of unpaid principal net of loan premiums or discounts for purchased loans, net deferred loan origination fees, discounts associated with retained portions of loans sold, and an allowance for loan losses. Interest on loans is calculated using the simple-interest method on daily balances of the principal amount outstanding. Loan origination fees, net of origination costs and discounts, are amortized over the lives of the loans as adjustments to yield.
	Major classifications of period-end loans are as follows:

	At June 30, 2014, outstanding loans to dental professionals totaled $302,822 and represented 29.37% of total outstanding loans compared to dental professional loans of $307,268 or 30.89% of total outstanding loans at December 31, 2013, and $290,543 or 30.25% of total outstanding loans at June 30, 2013. See Note 4 for additional information on the dental loan portfolio. There are no other industry concentrations in excess of 10% of the total loan portfolio. However, as of June 30, 2014, 61.45% of the Company’s loan portfolio was collateralized by real estate and is, therefore, susceptible to changes in real estate market conditions.
	Allowance for Loan Losses
	A summary of activity in the allowance for loan losses for the three and six months ended June 30, 2014, and 2013 is as follows:
			Three months ended						Six months ended
			June 30,						June 30,
			2014			2013			2014			2013
	Balance, beginning of period		$	15,394		$	16,312		$	15,917		$	16,345

	Loans charged against allowance			(30	)		(230	)		(631	)		(828	)
	Recoveries credited to allowance			311			221			389			536
	Balance, end of period		$	15,675		$	16,303		$	15,675		$	16,303
	The allowance for loan losses is established as an amount that management considers adequate to absorb possible losses on existing loans within the portfolio. The allowance consists of general, specific, and unallocated components. The general component is based upon all loans collectively evaluated for impairment. The specific component is based upon all loans individually evaluated for impairment. The unallocated component represents credit losses inherent in the loan portfolio that may not have been contemplated in the general risk factors or the specific allowance analysis. Loans are charged against the allowance when management believes the collection of principal or interest is unlikely.
	The Company performs regular credit reviews of the loan portfolio to determine the credit quality and adherence to underwriting standards. When loans are originated, they are assigned a risk rating that is reassessed periodically during the term of the loan through the credit review process and on an ongoing basis by management. The Company’s internal risk rating methodology assigns risk ratings ranging from one to ten, where a higher rating represents higher risk. The ten-point risk rating categories are a primary factor in determining an appropriate amount for the allowance for loan losses.
	Estimated credit losses reflect consideration of all significant factors that affect the collectability of the loan portfolio. The historical loss rate for each group of loans with similar risk characteristics is determined based on the Company’s own loss experience in that group. Historical loss experience and recent trends in losses provide a reasonable starting point for analysis, however they do not by themselves form a sufficient basis to determine the appropriate level for the allowance for loan losses. Qualitative or environmental factors that are likely to cause estimated credit losses to differ from historical losses are also considered, including but not limited to:
		•		Changes in international, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments,
		•		Changes in the nature and volume of the portfolio and in the terms of loans,
		•		Changes in the experience, ability, and depth of lending management and other relevant staff,
		•		Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans,
		•		Changes in the quality of the institution’s loan review system,
		•		Changes in the value of underlying collateral for collateral-dependent loans,
		•		The existence and effect of any concentrations of credit, and changes in the level of such concentrations,
		•		The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the institution’s existing portfolio,
		•		Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses, and
		•		Changes in the current and future US political environment, including debt ceiling negotiations, government shutdown and healthcare reform, that may affect national, regional and local economic conditions, taxation, or disruption of national or global financial markets.
	The adequacy of the allowance for loan losses and the reserve for unfunded commitments is determined using a systematic methodology and is monitored regularly based on management’s evaluation of numerous factors. For each portfolio segment, these factors include:
		•		The quality of the current loan portfolio,
		•		The trend in the migration of the loan portfolio’s risk ratings,
		•		The velocity of migration of losses and potential losses,
		•		Current economic conditions,
		•		Loan concentrations,
		•		Loan growth rates,
		•		Past-due and nonperforming trends,
		•		Evaluation of specific loss estimates for all significant problem loans,
		•		Recovery experience, and
		•		Peer comparison loss rates.
	A summary of the activity in the allowance for loan losses by major loan classification follows:

Management believes that the allowance for loan losses was adequate as of June 30, 2014. However, future loan losses may exceed the levels provided for in the allowance for loan losses and could possibly result in additional charges to the provision for loan losses.
Credit Quality Indicators
The Company uses the following loan grades, which are also often used by regulators when assessing the credit quality of a loan portfolio.
Pass – Credit exposure in this category ranges between the highest credit quality to average credit quality. Primary repayment sources generate satisfactory debt service coverage under normal conditions. Cash flow from recurring sources is expected to continue to produce adequate debt service capacity. There are many levels of credit quality contained in the Pass definition, but none of the loans contained in this category rise to the level of Special Mention. This category includes loans with an internal risk rating of 1-6.
Special Mention – A special mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. The Bank strictly and carefully employs the FDIC definition in assessing assets that may apply to this category. It is apparent that in many cases asset weaknesses relevant to this definition either (1) better fit a definition of a “well-defined weakness,” or (2) in management’s experience ultimately migrate to worse risk grade categories, such as Substandard and Doubtful. Consequently, management elects to downgrade most potential Special Mention credits to Substandard or Doubtful, and therefore adopts a conservative risk grade process in the use of the Special Mention risk grade. This category includes loans with an internal risk rating of 7.
Substandard – A Substandard asset is inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Loans in this category are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified Substandard. This category includes loans with an internal risk rating of 8.
Doubtful – An asset classified as Doubtful has all the weaknesses inherent in one classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions, and values, highly questionable and improbable. This category includes loans with an internal risk rating of 9.
Management strives to consistently apply these definitions when allocating its loans by loan grade. The loan portfolio is continuously monitored for changes in credit quality and management takes appropriate action to update the loan risk ratings accordingly. Management has not changed the Company’s policy towards its use of credit quality indicators during the periods reported.

At June 30, 2014, December 31, 2013, and June 30, 2013, the Company had $417, $532 and $718, respectively, in unfunded commitments on its classified loans, which is included in the calculation of our classified asset ratio.
Past Due and Nonaccrual Loans
The Company uses the terms “past due” and “delinquent” interchangeably. Amortizing loans are considered past due or delinquent based upon the number of contractually required payments not made. Delinquency status for all contractually matured loans, commercial and commercial real estate loans with non-monthly amortization, and all other extensions of credit is determined based upon the number of calendar months past due.
The following tables present an aging analysis of past due and nonaccrual loans at June 30, 2014, December 31, 2013, and June 30, 2013:

Impaired Loans
Regular credit reviews of the portfolio are performed to identify loans that are considered potentially impaired. A loan is considered impaired when, based on current information and events, the Company is unlikely to collect all principal and interest due according to the terms of the loan agreement. When the amount of the impairment represents a confirmed loss, it is charged off against the allowance for loan losses. Impaired loans are often reported net of government guarantees to the extent that the guarantees are expected to be collected. Impaired loans generally include all loans classified as nonaccrual and troubled debt restructurings. Impaired loans are included in the specific calculation of allowance for loan losses.
Accrual of interest is discontinued on impaired loans when management believes that, after considering economic and business conditions and collection efforts, the borrower’s financial condition is such that collection of principal or interest is doubtful. Accrued but uncollected interest is generally reversed when loans are placed on nonaccrual status. Interest income is subsequently recognized only to the extent cash payments are received satisfying all delinquent principal and interest amounts, and the prospects for future payments in accordance with the loan agreement appear relatively certain. In accordance with GAAP, payments received on nonaccrual loans are applied to the principal balance and no interest income is recognized. Interest income may be recognized on impaired loans that are not on nonaccrual status.

The recorded investment in impaired loans, net of government guarantees, totaled $9,531, $8,476 and $9,540 at June 30, 2014, December 31, 2013, and June 30, 2013, respectively.
Troubled Debt Restructurings
In the normal course of business, the Company may modify the terms of certain loans, attempting to protect as much of its investment as possible. Management evaluates the circumstances surrounding each modification to determine whether it is a troubled debt restructuring (“TDR”). TDRs exist when 1) the restructuring constitutes a concession, and 2) the debtor is experiencing financial difficulties.
The following table displays the Company’s TDRs by class at June 30, 2014, December 31, 2013, and June 30, 2013:

The recorded investment in TDRs on nonaccrual status totaled $2,260, $1,597, and $2,081 at June 30, 2014, December 31, 2013, and June 30, 2013, respectively. The Company’s policy is that loans placed on nonaccrual will typically remain on nonaccrual status until all principal and interest payments are brought current and the prospect for future payment in accordance with the loan agreement appears relatively certain. The Company’s policy generally refers to six months of payment performance as sufficient to warrant a return to accrual status.
For the six months ended June 30, 2014, the Company identified four TDRs that were newly considered impaired for which impairment was previously measured under the Company’s general loan loss allowance methodology. At June 30, 2014, the total recorded investment in such receivables was $2,455, and the associated allowance for loan losses was $0.
The types of modifications offered can generally be described in the following categories:
Rate Modification - A modification in which the interest rate is modified.
Term Modification - A modification in which the maturity date, timing of payments, or frequency of payments is changed.
Interest-only Modification - A modification in which the loan is converted to interest-only payments for a period of time.
Combination Modification - Any other type of modification, including the use of multiple types of modifications.
The following tables present newly restructured loans that occurred during the six months ended June 30, 2014, and 2013, respectively:

Subsequent to a loan being classified as a TDR, a borrower may become unwilling or unable to abide by the terms of the modified agreement. In such cases of default, the Company takes appropriate action to recover principal and interest payments including the use of foreclosure proceedings.

	NOTE 4 – DENTAL LOAN PORTFOLIO
	To assist in understanding the concentrations and risks associated with the Company’s loan portfolio, the following Note has been included to provide additional information relating to the Company’s dental loan portfolio. At June 30, 2014, December 31, 2013, and June 30, 2013, loans to dental professionals totaled $302,822, $307,268, and $290,543, respectively, and represented 29.37%, 30.89% and 30.25% in principal amount of total outstanding loans as of such dates. As of June 30, 2014, December 31, 2013, and June 30, 2013, the dental loans were supported by government guarantees totaling $13,967, $16,470 and $17,272, respectively. These guarantees represented 4.61%, 5.36% and 5.94% in principal amount of the outstanding dental loan balances as of such respective dates. The Company defines a “dental loan” as a loan to dental professionals for the purpose of practice expansion, acquisition or other purpose supported by the cash flows of a dental practice.

	Allowance
	The allowance for loan losses identified for the dental loan portfolio is established as an amount that management considers adequate to absorb possible losses on existing loans within the dental loan portfolio. The allowance related to the dental loan portfolio consists of general and specific components. The general component is based upon all dental loans collectively evaluated for impairment, including qualitative conditions associated with loan type, national location, start-up financing, practice acquisition financing, and specialty practice financing. The specific component is based upon dental loans individually evaluated for impairment.

	NOTE 6 – FEDERAL HOME LOAN BANK BORROWINGS
	The Company has a borrowing limit with the Federal Home Loan Bank (“FHLB”) equal to 30% of total assets, subject to the value of discounted collateral pledged. The Company does have the ability to access the FHLB excess stock pool, thus borrowing is not limited by FHLB stock held. At June 30, 2014, the maximum borrowing line was $449,629; however, the FHLB borrowing line was limited by the discounted value of collateral pledged. The Company had pledged $461,303 in real estate loans to the FHLB that had a discounted value of $284,453. There was $164,500 borrowed on this line at June 30, 2014.
	At December 31, 2013, the maximum FHLB borrowing line was $434,963, and the Company had pledged real estate loans and securities to the FHLB with a discounted value of $229,547. There was $160,000 borrowed on this line at December 31, 2013.
	At June 30, 2013, the maximum FHLB borrowing line was $429,322, and the Company had pledged real estate loans and securities to the FHLB with a discounted collateral value of $265,048. There was $162,000 borrowed on this line at June 30, 2013.

Share-Based Compensation	'
	NOTE 7 – SHARE-BASED COMPENSATION
	The Company’s 2006 Stock Option and Equity Compensation Plan (the “2006 SOEC Plan”) authorizes the award of up to 1,550,000 shares in share-based awards. The awards granted under this plan are performance-based and are subject to vesting. The Compensation Committee of the Board of Directors may impose any terms or conditions on the vesting of an award that it determines to be appropriate. Awards granted generally vest over four years and have a maximum life of ten years. Awards may be granted at exercise prices of not less than 100% of the fair market value of the Company’s common stock at the grant date.
	Pursuant to the 2006 SOEC Plan, incentive stock options (“ISOs”), nonqualified stock options, restricted stock, restricted stock units (“RSUs”), or stock appreciation rights (“SARs”) may be awarded to attract and retain the best available personnel to the Company and its subsidiaries. SARs may be settled in common stock or cash as determined at the date of issuance. Liability-based awards (including all cash-settled SARs) have no impact on the number of shares available to be issued within the plan. Additionally, non-qualified option awards and restricted stock awards may be granted to directors under the terms of this plan.
	Prior to April 2006, ISO and non-qualified option awards were granted to employees and directors under the Company’s 1999 Employees’ Stock Option Plan and the Company’s 1999 Directors’ Stock Option Plan. The Company has stock options outstanding under both of these plans. Subsequent to the annual shareholders’ meeting in April 2006, all shares available under these plans were deregistered and are no longer available for future grants.
	For the six months ended June 30, 2014, 14,996 restricted shares were granted and issued to directors with no restrictions imposed. Additionally, 127,051 RSUs were granted to employees during the first six months of 2014. Of the 127,051 RSUs granted, 116,771 vest over four years, 9,902 vest over two years, and 378 vested immediately. Shares of common stock will be issued as soon as practicable upon vesting. For the six months ended June 30, 2013, 10,179 restricted shares were granted and issued to directors with no restrictions imposed. Additionally, 145,420 RSUs were granted to employees during the first six months of 2013 which vest over four years. No other awards were granted during the six months ended June 30, 2014, and 2013.
	The following table summarizes the shares and the grant-date fair market values of the equity-based awards granted during the three months ended June 30, 2014, and 2013:

No liability-based awards vested during the three months ended June 30, 2014. The fair value of the liability-based awards vested during the three months ended June 30, 2013 was $29.
At June 30, 2014, the Company had estimated unrecognized compensation expense of approximately $3,040 for unvested RSUs. These amounts are based on forfeiture rates of 20.00% for all stock options and SARs and 13.00% for all RSUs granted to employees. The weighted-average period of time the unrecognized compensation expense will be recognized for the unvested RSUs was approximately 2.91 years as of June 30, 2014.

	Cash and cash equivalents – The carrying amount approximates fair value.
	Securities available-for-sale – Fair value is based on quoted market prices. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities.
	Loans – For variable rate loans that reprice frequently and have no significant change in credit risk, fair value is based on carrying values. Fair value of fixed rate loans is estimated by discounting the future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Fair values for impaired loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable, and consider credit risk.
	Federal Home Loan Bank stock – The carrying amount approximates fair value.
	Interest receivable and payable – The carrying amounts of accrued interest receivable and payable approximate their fair value.
	Bank-owned life insurance – The carrying amount is based on cash surrender value which approximates fair value.
	Swap derivative – Fair value is based on quoted market prices.
	Deposits – Fair value of demand, interest bearing demand and savings deposits is the amount payable on demand at the reporting date. Fair value of time deposits is estimated using the interest rates currently offered for deposits of similar remaining maturities. The Company uses an independent third-party to establish the fair value of time deposits.
	Federal funds and overnight funds purchased – The carrying amount is a reasonable estimate of fair value because of the short-term nature of these borrowings.
	Federal Home Loan Bank borrowings – Fair value of Federal Home Loan Bank borrowings is estimated by discounting future cash flows at rates currently available for debt with similar terms and remaining maturities.
	Junior subordinated debentures – Fair value of junior subordinated debentures is estimated by discounting future cash flows at rates currently available for debt with similar credit risk, terms and remaining maturities.
	Off-Balance Sheet Financial Instruments – The carrying amount and fair value are based on fees charged for similar commitments and are not material.
	The Company also adheres to the FASB guidance with regards to ASC 820, “Fair Value Measures.” This guidance defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. The statement requires fair value measurement disclosure of all assets and liabilities that are carried at fair value on either a recurring or nonrecurring basis. The Company determines fair value based upon quoted prices when available or through the use of alternative approaches, such as matrix or model pricing, when market quotes are not readily accessible or available. The valuation techniques used are based on observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy:
		•		Level 1 – Quoted prices for identical instruments in active markets.
		•		Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active or model-derived valuations whose inputs are observable or whose significant value drivers are observable.
		•		Level 3 – Unobservable inputs are used to measure fair value to the extent that observable inputs are not available. The Company’s own data used to develop unobservable inputs is adjusted for market consideration when reasonably available.
	Financial instruments, measured at fair value, are broken down in the tables below by recurring or nonrecurring measurement status. Recurring assets are initially measured at fair value and are required to be remeasured at fair value in the financial statements at each reporting date. Assets measured on a nonrecurring basis are assets that, due to an event or circumstance, were required to be remeasured at fair value after initial recognition in the financial statements at some time during the reporting period.
	The following table presents information about the level in the fair value hierarchy for the Company’s assets and liabilities not measured and carried at fair value as of June 30, 2014, December 31, 2013, and June 30, 2013:

No transfers to or from Levels 1 and 2 occurred on assets measured at fair value on a recurring basis during the six months ended June 30, 2014, and 2013, or during the year ended December 31, 2013.
The following is a description of the inputs and valuation methodologies used for assets recorded at fair value on a recurring basis. Fair value for all classes of available-for-sale securities is estimated by obtaining quoted market prices for identical assets, where available. If such prices are not available, fair value is based on independent asset pricing services and models, the inputs of which are market-based or independently sourced market parameters, including, but not limited to, yield curves, interest rates, prepayments, defaults, cumulative loss projections, and cash flows. Fair value of the swap derivative is determined by FTN Financial, and represents an active price quote which they would pay or the Bank would be charged to leave the swap early. There have been no significant changes in the valuation techniques during the periods reported.
The following table provides a reconciliation of assets measured at fair value on a recurring basis using unobservable inputs (Level 3) for the three and six months ended June 30, 2014, and 2013:

The Company utilizes FTN Financial as a third-party pricing service to estimate fair value on all of its available-for-sale securities. The inputs used to value all securities include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data, including market research, market indicators, and industry and economic trends. Additional inputs specific to each asset type are as follows:
	•		Obligations of U.S. government agencies – TRACE reported trades.

	•		SBA variable pools – TBA prices and monthly payment information.
Inputs may be prioritized differently on any given day for any security and not all inputs listed are available for use in the evaluation process on any given day for each security evaluation.
The valuation methodology used by asset type includes:
	•		Obligations of U.S. government agencies – security characteristics, defined sector break-down, benchmark yields, applied base spread, yield to maturity (bullet structures), corporate action adjustment, and evaluations based on T+3 settlement.
	•		Obligations of states and political subdivisions – security characteristics, benchmark yields, applied base spread, yield to worst or market convention, ratings updates, prepayment schedules (housing bonds), material event notice adjustments, and evaluations based on T+3 settlement.
	•		Private-label mortgage-backed securities – security characteristics, prepayment speeds, cash flows, TBA, Treasury and swap curves, IO/PO strips or floating indexes, applied base spread, spread adjustments, yield to worst or market convention, ratings updates (whole-loan collateral), and evaluations based on T+0 settlement.
	•		Mortgage-backed securities – security characteristics, TBA, Treasury, or floating index benchmarks, spread to TBA levels, prepayment speeds, applied spreads, and evaluations based on T+0 settlement.
	•		SBA variable pools – security characteristics, TBA, Treasury, or floating index benchmarks, spread to TBA levels, prepayment speeds, applied spreads, and evaluations based on T+0 settlement.
The third-party pricing service follows multiple review processes to assess the available market, credit and deal-level information to support its valuation estimates. If sufficient objectively verifiable information is not available to support a security’s valuation, an alternate independent evaluation source will be used.
The Company’s securities portfolio was valued through its independent third-party pricing service using evaluated pricing models and quoted prices based on market data. For further assurance, the Company’s estimate of fair value was compared to an additional independent third-party estimate at June 30, 2014, and the Company obtained key inputs for a sample of securities across sectors and evaluated those inputs for reasonableness. This analysis was performed at the individual security level and no material variances were noted.
There have been no significant changes in the valuation techniques during the periods reported.

The following is a description of the inputs and valuation methodologies used for assets recorded at fair value on a nonrecurring basis.
Loans measured for impairment (net of government guarantees and specific reserves) include the estimated fair value of collateral-dependent loans, less collectible government guarantees, as well as certain noncollateral-dependent loans measured for impairment with an allocated specific reserve. When a collateral-dependent loan is identified as impaired, the value of the loan is measured using the current fair value of the collateral less selling costs. The fair value of collateral is generally estimated by obtaining external appraisals which are usually updated every 6 to 12 months based on the nature of the impaired loans. Certain noncollateral-dependent loans measured for impairment with an allocated specific reserve are valued based upon the estimated net realizable value of the loan. If the estimated fair value of the impaired loan, less collectible government guarantees, is less than the recorded investment in the loan, impairment is recognized as a charge-off through the allowance for loan losses. The carrying value of the loan is adjusted to the estimated fair value. The carrying value of loans fully charged off is zero.
Other real estate owned represents real estate which the Company has taken control of in partial or full satisfaction of loans. At the time of foreclosure, other real estate owned is recorded at the lower of the carrying amount of the loan or fair value less costs to sell, which becomes the property’s new basis. Any write downs based on the asset’s fair value at the date of acquisition are charged to the allowance for loan losses. After foreclosure, management periodically orders appraisals or performs valuations to ensure that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Appraisals are generally updated every 6 to 12 months on other real estate owned. Fair value adjustments on other real estate owned are recognized within net loss on real estate owned. The loss represents impairments on other real estate owned for fair value adjustments based on the fair value of the real estate.
There have been no significant changes in the valuation techniques during the periods reported.

Derivative Instruments	'
	NOTE 9 – DERIVATIVE INSTRUMENTS
	Derivative instruments are entered into primarily as a risk management tool of the Company to help manage its interest rate risk position. Financial derivatives are recorded at fair value as other assets and other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For a fair value hedge, changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability are recognized currently in earnings. For a cash flow hedge, changes in the fair value of the derivative instrument, to the extent that it is effective, are recorded in accumulated other comprehensive income and subsequently reclassified to earnings as the hedged transaction impacts net income. Any ineffective portion of a cash flow hedge is recognized currently in earnings.
	During the second quarter 2013, the Company entered into an interest rate swap agreement with an $8,000 notional amount to convert its variable-rate Junior Subordinated Debenture debt into a fixed rate for a term of seven years at a rate of 2.73%. The derivative is designated as a cash flow hedge. The hedge meets the definition of highly effective and the Company expects the hedge to be highly effective throughout the remaining term of the swap. The fair value of the derivative instrument at June 30, 2014, was a $218 unrealized gain, which is recorded in the other asset section of the consolidated balance sheet, net of the tax effect. No gain or loss was recognized in earnings for the six months ended June 30, 2014, related to interest rate swaps.
	The Company maintains written documentation for the hedge. This documentation identifies the hedging objective and strategy, the hedging instrument, the instrument being hedged, the reasoning behind the assertion that the hedge is highly effective and the methodology for measuring ongoing hedge effectiveness and ineffectiveness. The Company pledged $400 under collateral arrangements to satisfy collateral requirements associated with the interest rate swap contract.

Regulatory Matters	'
	NOTE 10 – REGULATORY MATTERS
	The Company and the Bank are subject to the regulations of certain federal and state agencies and receive periodic examinations by those regulatory authorities. In addition, they are subject to various regulatory capital requirements administered by federal banking agencies. 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’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Company and the Bank’s capital amounts and classification 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 Bank to maintain minimum amounts and ratios of Total and Tier 1 capital to risk-weighted assets and of Tier 1 capital to leverage assets. Management believes that, as of June 30, 2014, the Company and the Bank met all capital adequacy requirements to which they are subject.
	As of June 30, 2014, and according to Federal Reserve and FDIC guidelines, the Bank was considered to be well-capitalized. To be categorized as well-capitalized, the Bank must maintain minimum Total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the following table.

Accounting Policies [Abstract]	'
Basis of Presentation	'
	The accompanying consolidated financial statements have been prepared by the Company without audit and in conformity with generally accepted accounting principles in the United States of America for interim financial information. The consolidated financial statements include all adjustments and normal accruals, which the Company considers necessary for a fair presentation of the results of operations for such interim periods. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, as of the date of the balance sheets and income and expenses for the periods. Actual results could differ from those estimates.
	The balance sheet data as of December 31, 2013, was derived from audited financial statements, but does not include all disclosures contained in the Company’s 2013 Form 10-K. The interim consolidated financial statements should be read in conjunction with the December 31, 2013, consolidated financial statements, including the notes thereto, included in the Company’s 2013 Form 10-K.
Loans	'
	Loans are stated at the amount of unpaid principal net of loan premiums or discounts for purchased loans, net deferred loan origination fees, discounts associated with retained portions of loans sold, and an allowance for loan losses. Interest on loans is calculated using the simple-interest method on daily balances of the principal amount outstanding. Loan origination fees, net of origination costs and discounts, are amortized over the lives of the loans as adjustments to yield.
Allowance for Loan Losses	'
	The allowance for loan losses is established as an amount that management considers adequate to absorb possible losses on existing loans within the portfolio. The allowance consists of general, specific, and unallocated components. The general component is based upon all loans collectively evaluated for impairment. The specific component is based upon all loans individually evaluated for impairment. The unallocated component represents credit losses inherent in the loan portfolio that may not have been contemplated in the general risk factors or the specific allowance analysis. Loans are charged against the allowance when management believes the collection of principal or interest is unlikely.
	The Company performs regular credit reviews of the loan portfolio to determine the credit quality and adherence to underwriting standards. When loans are originated, they are assigned a risk rating that is reassessed periodically during the term of the loan through the credit review process and on an ongoing basis by management. The Company’s internal risk rating methodology assigns risk ratings ranging from one to ten, where a higher rating represents higher risk. The ten-point risk rating categories are a primary factor in determining an appropriate amount for the allowance for loan losses.
	Estimated credit losses reflect consideration of all significant factors that affect the collectability of the loan portfolio. The historical loss rate for each group of loans with similar risk characteristics is determined based on the Company’s own loss experience in that group. Historical loss experience and recent trends in losses provide a reasonable starting point for analysis, however they do not by themselves form a sufficient basis to determine the appropriate level for the allowance for loan losses. Qualitative or environmental factors that are likely to cause estimated credit losses to differ from historical losses are also considered, including but not limited to:
		•	Changes in international, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments,
		•	Changes in the nature and volume of the portfolio and in the terms of loans,
		•	Changes in the experience, ability, and depth of lending management and other relevant staff,
		•	Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans,
		•	Changes in the quality of the institution’s loan review system,
		•	Changes in the value of underlying collateral for collateral-dependent loans,
		•	The existence and effect of any concentrations of credit, and changes in the level of such concentrations,
		•	The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the institution’s existing portfolio,
		•	Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses, and
		•	Changes in the current and future US political environment, including debt ceiling negotiations, government shutdown and healthcare reform, that may affect national, regional and local economic conditions, taxation, or disruption of national or global financial markets.
	The adequacy of the allowance for loan losses and the reserve for unfunded commitments is determined using a systematic methodology and is monitored regularly based on management’s evaluation of numerous factors. For each portfolio segment, these factors include:
		•	The quality of the current loan portfolio,
		•	The trend in the migration of the loan portfolio’s risk ratings,
		•	The velocity of migration of losses and potential losses,
		•	Current economic conditions,
		•	Loan concentrations,
		•	Loan growth rates,
		•	Past-due and nonperforming trends,
		•	Evaluation of specific loss estimates for all significant problem loans,
		•	Recovery experience, and
		•	Peer comparison loss rates.
Fair Value Measurements	'
	The Company also adheres to the FASB guidance with regards to ASC 820, “Fair Value Measures.” This guidance defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. The statement requires fair value measurement disclosure of all assets and liabilities that are carried at fair value on either a recurring or nonrecurring basis. The Company determines fair value based upon quoted prices when available or through the use of alternative approaches, such as matrix or model pricing, when market quotes are not readily accessible or available. The valuation techniques used are based on observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy:
		•	Level 1 – Quoted prices for identical instruments in active markets.
		•	Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active or model-derived valuations whose inputs are observable or whose significant value drivers are observable.
		•	Level 3 – Unobservable inputs are used to measure fair value to the extent that observable inputs are not available. The Company’s own data used to develop unobservable inputs is adjusted for market consideration when reasonably available.
	Financial instruments, measured at fair value, are broken down in the tables below by recurring or nonrecurring measurement status. Recurring assets are initially measured at fair value and are required to be remeasured at fair value in the financial statements at each reporting date. Assets measured on a nonrecurring basis are assets that, due to an event or circumstance, were required to be remeasured at fair value after initial recognition in the financial statements at some time during the reporting period.
Derivative Instruments and Hedging Activities	'
	Derivative instruments are entered into primarily as a risk management tool of the Company to help manage its interest rate risk position. Financial derivatives are recorded at fair value as other assets and other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For a fair value hedge, changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability are recognized currently in earnings. For a cash flow hedge, changes in the fair value of the derivative instrument, to the extent that it is effective, are recorded in accumulated other comprehensive income and subsequently reclassified to earnings as the hedged transaction impacts net income. Any ineffective portion of a cash flow hedge is recognized currently in earnings.
