Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1. Summary of Significant Accounting Policies Nature of Business Basis of Presentation These consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. Significant intercompany transactions and accounts are eliminated in consolidation. Use of Estimates Loans — Loans are charged off when management believes that the full collectability of the loan is unlikely. As such, a loan may be partially charged-off after a “confirming event” has occurred which serves to validate that full repayment pursuant to the terms of the loan is unlikely. Loans are placed on nonaccrual status when there is a significant deterioration in the financial condition of the borrower, which often is determined when the principal or interest is more than 90 days past due, unless the loan is both well-secured and in the process of collection. Generally, all interest accrued but not collected for loans that are placed on nonaccrual status, is reversed against current income. Interest income is subsequently recognized only to the extent cash payments are received while the loan is classified as nonaccrual, but interest income recognition is reviewed on a case-by-case basis. A nonaccrual loan is returned to accruing status once the loan has been brought current and collection is reasonably assured or the loan has been “well-secured” through other techniques. Past due status is determined based on the contractual due date per the underlying loan agreement. All loans that are placed on nonaccrual are further analyzed to determine if they should be classified as impaired loans. At December 31, 2014 and at June 30, 2015, there were no loans classified as nonaccrual that were not also deemed to be impaired except for those loans not individually evaluated for impairment as described below. A loan is considered to be impaired when it is probable the Company will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan. This determination is made using a variety of techniques, which include a review of the borrower’s financial condition, debt-service coverage ratios, global cash flow analysis, guarantor support, other loan file information, meetings with borrowers, inspection or reappraisal of collateral and/or consultation with legal counsel as well as results of reviews of other similar industry credits (e.g. builder loans, development loans, church loans, etc). Prior to January 1, 2015, loans with an identified weakness and principal balance of $100,000 or more were subject to individual identification for impairment. During the first quarter of 2015, the Company increased the threshold for identification of individually impaired loans to $500,000, based on regulatory developments, continued improvement in loan quality trends and ratios and strengthening local economies in which the Company operates. Management believes that increasing the threshold will not materially impact the calculation of the allowance for loan losses. Individually identified impaired loans are measured based on the present value of expected payments using the loan’s original effective rate as the discount rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. If the recorded investment in the impaired loan exceeds the measure of fair value, a specific valuation allowance is established as a component of the allowance for loan losses or, in the case of collateral dependent loans, the excess may be charged off. Changes to the valuation allowance are recorded as a component of the provision for loan losses. Any subsequent adjustments to present value calculations for impaired loan valuations as a result of the passage of time, such as changes in the anticipated payback period for repayment, are recorded as a component of the provision for loan losses. For loans less than $500,000, the Company assigns a valuation allowance to these loans utilizing an allocation rate equal to the allocation rate calculated for non-impaired loans of a similar type greater than $500,000 and for homogeneous pools of loans collectively evaluated. Allowance for Loan Losses — In assessing the adequacy of the allowance, we also consider the results of our ongoing independent loan review process. We undertake this process both to ascertain whether there are loans in the portfolio whose credit quality has weakened over time and to assist in our overall evaluation of the risk characteristics of the entire loan portfolio. Our loan review process includes the judgment of management, independent loan reviewers, and reviews that may have been conducted by third-party reviewers. We incorporate relevant loan review results in the loan impairment determination. In addition, regulatory agencies, as an integral part of their examination process, will periodically review the Company’s allowance for loan losses, and may require the Company to record adjustments to the allowance based on their judgment about information available to them at the time of their examinations. Recently Adopted Accounting Pronouncements There were no recently issued accounting pronouncements that are expected to materially impact the Company.

Loans and Allowance for Loan Losses	Note 2. Loans and Allowance for Loan Losses For financial reporting purposes, the Company classifies its loan portfolio based on the underlying collateral utilized to secure each loan. This classification is consistent with those utilized in the Quarterly Report of Condition and Income filed by the Bank with the Federal Deposit Insurance Corporation (“FDIC”). The following schedule details the loans of the Company at June 30, 2015 and December 31, 2014: (In Thousands) June 30, December 31, Mortgage loans on real estate Residential 1-4 family $ 355,924 $ 350,758 Multifamily 50,559 31,242 Commercial 585,217 564,965 Construction and land development 277,518 245,830 Farmland 31,479 30,236 Second mortgages 8,681 9,026 Equity lines of credit 45,818 41,496 Total mortgage loans on real estate 1,355,196 1,273,553 Commercial loans 29,532 30,000 Agricultural loans 1,451 1,670 Consumer installment loans Personal 39,279 37,745 Credit cards 3,169 3,280 Total consumer installment loans 42,448 41,025 Other loans 9,592 10,530 1,438,219 1,356,778 Net deferred loan fees (4,758 ) (4,341 ) Total loans 1,433,461 1,352,437 Less: Allowance for loan losses (22,412 ) (22,572 ) Net Loans $ 1,411,049 $ 1,329,865 The adequacy of the allowance for loan losses is assessed at the end of each calendar quarter. The level of the allowance is based upon evaluation of the loan portfolio, past loan loss experience, current asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers’ ability to repay (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan portfolio, economic conditions, historical loss experience, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations.

These loans are classified as impaired loans and, if on non-accruing status as of the date of restructuring, the loans are included in the nonperforming loan balances. Not included in nonperforming loans are loans that have been restructured that were performing as of the restructure date. Troubled Debt Restructuring The Bank’s loan portfolio includes certain loans that have been modified in a troubled debt restructuring (TDR), where economic concessions have been granted to borrowers who have experienced or are expected to experience financial difficulties. These concessions typically result from the Bank’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. Certain TDRs are classified as nonperforming at the time of restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months. The following table summarizes the carrying balances of TDR’s at June 30, 2015 and December 31, 2014. June 30, 2015 December 31, 2014 (In thousands) Performing TDRs $ 4,226 $ 4,443 Nonperforming TDRs 3,035 3,597 Total TDRS $ 7,261 $ 8,040 The following table outlines the amount of each troubled debt restructuring categorized by loan classification for the six months ended June 30, 2015 and the year ended December 31, 2014 (in thousands, except for number of contracts): June 30, 2015 December 31, 2014 Number Pre Post Number Pre Post Residential 1-4 family 1 $ 56 $ 56 6 $ 1,346 $ 1,218 Multifamily — — — — — — Commercial real estate — — — 2 1,020 1,020 Construction — — — — — — Farmland — — — — — — Second mortgages — — — — — — Equity lines of credit — — — — — — Commercial — — — 1 3 3 Agricultural, installment and other 1 2 2 1 1 1 Total 2 $ 58 $ 58 10 $ 2,370 $ 2,242 As of June 30, 2015, the Company had one loan relationship in the amount of $1.0 million that had been previously classified as a troubled debt restructuring that subsequently defaulted within twelve months of restructuring. As of December 31, 2014, the Company did not have any loans previously classified as troubled debt restructurings subsequently default within twelve months of restructuring. A default is defined as an occurrence which violates the terms of the receivable’s contract. As of June 30, 2015, the Company’s recorded investment in consumer mortgage loans in the process of foreclosure amounted to $601,000. Potential problem loans, which include nonperforming loans, amounted to approximately $34.1 million at June 30, 2015 compared to $35.8 million at December 31, 2014. Potential problem loans represent those loans with a well-defined weakness and where information about possible credit problems of borrowers has caused management to have serious doubts about the borrower’s ability to comply with present repayment terms. This definition is believed to be substantially consistent with the standards established by the FDIC, the Bank’s primary federal regulator, for loans classified as special mention, substandard, or doubtful. The following summary presents our loan balances by primary loan classification and the amount classified within each risk rating category. Pass rated loans include all credits other than those included in special mention, substandard and doubtful which are defined as follows: • Special mention loans have 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 Bank’s credit position at some future date. • Substandard loans are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize liquidation of the debt. Substandard loans are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. • Doubtful loans have all the characteristics of substandard loans 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. The Bank considers all doubtful loans to be impaired and places the loan on nonaccrual status.

Debt and Equity Securities	Note 3. Debt and Equity Securities Debt and equity securities have been classified in the consolidated balance sheet according to management’s intent. Debt and equity securities at June 30, 2014 and December 31, 2013 are summarized as follows: June 30, 2015 Securities Available-For-Sale In Thousands Amortized Gross Gross Estimated U.S. Government-sponsored enterprises (GSEs)* $ 113,691 $ 241 $ 787 $ 113,145 Mortgage-backed: GSE residential 163,538 477 857 163,158 Asset-backed: SBAP 29,147 92 122 29,117 Obligations of states and political subdivisions 23,279 37 252 23,064 $ 329,655 $ 847 $ 2,018 $ 328,484 June 30, 2015 Securities Held-To-Maturity In Thousands Amortized Gross Gross Estimated Mortgage-backed: Government-sponsored enterprises (GSEs)* residential $ 7,189 $ 67 $ 191 $ 7,065 Obligations of states and political subdivisions 19,015 258 87 19,186 $ 26,204 $ 325 $ 278 $ 26,251 * Such as Federal National Mortgage Association, Federal Home Loan Mortgage Corporation, Federal Home Loan Bank, and Federal Farm Credit Bank.

The amortized cost and estimated market value of debt securities at June 30, 2015, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

The issuers continues to make timely principal and interest payment on the securities. The fair value is expected to recover as the securities approach maturity. The Company does not consider these securities to be other-than-temporarily impaired at June 30, 2015. The carrying values of the Company’s investment securities could decline in the future if the financial condition of issuers deteriorate and management determines it is probable that the Company will not recover the entire amortized cost bases of the securities. As a result, there is a risk that other-than-temporary impairment charges may occur in the future given the current economic environment.

Earnings Per Share [Abstract]
Earnings Per Share	Note 4. Earnings Per Share The computation of basic earnings per share is based on the weighted average number of common shares outstanding during the period. The computation of diluted earnings per share for the Company begins with the basic earnings per share plus the effect of common shares contingently issuable from stock options. The following is a summary of components comprising basic and diluted earnings per share (“EPS”) for the three and six months ended June 30, 2015 and 2014: Three Months Ended June 30, Six Months Ended June 30, 2015 2014 2015 2014 (Dollars in Thousands (Dollars in Thousands Except Per Share Amounts) Except Per Share Amounts) Basic EPS Computation: Numerator – Earnings available to common stockholders $ 6,201 $ 5,154 $ 11,817 $ 9,326 Denominator – Weighted average number of common shares outstanding 7,610,002 7,534,761 7,603,734 7,528,555 Basic earnings per common share $ .81 $ .68 $ 1.55 $ 1.24 Diluted EPS Computation: Numerator – Earnings available to common stockholders $ 6,201 $ 5,154 $ 11,817 $ 9,326 Denominator – Weighted average number of common shares outstanding 7,610,002 7,534,761 7,603,734 7,528,555 Dilutive effect of stock options 3,366 4,471 3,451 4,486 7,613,368 7,539,232 7,607,185 7,533,041 Diluted earnings per common share $ .81 $ .68 $ 1.55 $ 1.24

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Note 6. Commitments and Contingent Liabilities In the normal course of business, the Bank has entered into off-balance sheet financial instruments which include commitments to extend credit (i.e., including unfunded lines of credit) and standby letters of credit. Commitments to extend credit are usually the result of lines of credit granted to existing borrowers under agreements that the total outstanding indebtedness will not exceed a specific amount during the term of the indebtedness. Typical borrowers are commercial concerns that use lines of credit to supplement their treasury management functions, thus their total outstanding indebtedness may fluctuate during any time period based on the seasonality of their business and the resultant timing of their cash flows. Other typical lines of credit are related to home equity loans granted to consumers. Commitments to extend credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. Standby letters of credit are generally issued on behalf of an applicant (our customer) to a specifically named beneficiary and are the result of a particular business arrangement that exists between the applicant and the beneficiary. Standby letters of credit have fixed expiration dates and are usually for terms of two years or less unless terminated beforehand due to criteria specified in the standby letter of credit. A typical arrangement involves the applicant routinely being indebted to the beneficiary for such items as inventory purchases, insurance, utilities, lease guarantees or other third party commercial transactions. The standby letter of credit would permit the beneficiary to obtain payment from the Company under certain prescribed circumstances. Subsequently, the Company would then seek reimbursement from the applicant pursuant to the terms of the standby letter of credit. The Company follows the same credit policies and underwriting practices when making these commitments as it does for on-balance sheet instruments. Each customer’s creditworthiness is evaluated on a case-by-case basis, and the amount of collateral obtained, if any, is based on management’s credit evaluation of the customer. Collateral held varies but may include cash, real estate and improvements, marketable securities, accounts receivable, inventory, equipment, and personal property. The contractual amounts of these commitments are not reflected in the consolidated financial statements and would only be reflected if drawn upon. Since many of the commitments are expected to expire without being drawn upon, the contractual amounts do not necessarily represent future cash requirements. However, should the commitments be drawn upon and should our customers default on their resulting obligation to us, the Company’s maximum exposure to credit loss, without consideration of collateral, is represented by the contractual amount of those instruments. A summary of the Company’s total contractual amount for all off-balance sheet commitments at June 30, 2015 is as follows: Commitments to extend credit $ 329,816,000 Standby letters of credit $ 33,214,000 The Company originates residential mortgage loans, sells them to third-party purchasers, and does not retain the servicing rights. These loans are originated internally and are primarily to borrowers in the Company’s geographic market footprint. These sales are on a best efforts basis to investors that follow conventional government sponsored entities (GSE) and the Department of Housing and Urban Development/U.S. Department of Veterans Affairs (HUD/VA) guidelines. Generally, loans held for sale are underwritten by the Company, including HUD/VA loans. Each purchaser has specific guidelines and criteria for sellers of loans, and the risk of credit loss with regard to the principal amount of the loans sold is generally transferred to the purchasers upon sale. While the loans are sold without recourse, the purchase agreements require the Company to make certain representations and warranties regarding the existence and sufficiency of file documentation and the absence of fraud by borrowers or other third parties such as appraisers in connection with obtaining the loan. If it is determined that the loans sold were in breach of these representations or warranties or the loan had an early payoff or payment default, the Company has obligations to either repurchase the loan for the unpaid principal balance and related investor fees or make the purchaser whole for the economic benefits of the loan. To date, repurchase activity pursuant to the terms of these representations and warranties has been insignificant and has resulted in insignificant losses to the Company. Based on information currently available, management believes that it does not have significant exposure to contingent losses that may arise relating to the representations and warranties that it has made in connection with its mortgage loan sales. Various legal claims also arise from time to time in the normal course of business. In the opinion of management, the resolution of these claims outstanding at June 30, 2015 will not have a material impact on the Company’s financial statements.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 7. Fair Value Measurements FASB ASC 820, Fair Value Measurements and Disclosures Valuation Hierarchy FASB ASC 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows: • Level 1 — inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 — inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 — inputs to the valuation methodology are unobservable and significant to the fair value measurement. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy. Assets Securities available-for-sale — Impaired loans — Other real estate owned — Mortgage loans held-for-sale Other assets The following tables present the financial instruments carried at fair value as of June 30, 2015 and December 31, 2014, by caption on the consolidated balance sheet and by FASB ASC 820 valuation hierarchy (as described above) (in thousands): Assets and Liabilities Measured at Fair Value on a Recurring Basis Models with Models with Total Carrying Significant Significant Value in the Quoted Market Observable Unobservable Consolidated Prices in an Market Market Balance Active Market Parameters Parameters Sheet (Level 1) (Level 2) (Level 3) June 30, 2015 Investment securities available-for-sale: U.S. Government sponsored enterprises $ 113,145 — 113,145 — Mortgage-backed securities 163,158 — 163,158 — Asset-backed securities 29,117 — 29,117 — State and municipal securities 23,064 — 23,064 — Total investment securities available-for-sale 328,484 — 328,484 — Loans held for sale 10,076 — 10,076 — Other assets 25,543 — — 25,543 Total assets at fair value $ 364,103 — 338,560 25,543 December 31, 2014 Investment securities available-for-sale: U.S. Government sponsored enterprises $ 130,567 — 130,567 — Mortgage-backed securities 171,069 — 171,069 — Asset-backed securities 30,520 — 30,520 — State and municipal securities 14,264 — 14,264 — Total investment securities available-for-sale 346,420 — 346,420 — Loans held for sale 9,466 — 9,466 — Other assets 17,331 — — 17,331 Total assets at fair value $ 373,217 — 355,886 17,331 Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis Models with Models with Total Carrying Significant Significant Value in the Quoted Market Observable Unobservable Consolidated Prices in an Market Market Balance Active Market Parameters Parameters Sheet (Level 1) (Level 2) (Level 3) June 30, 2015 Other real estate owned $ 6,477 — — 6,477 Impaired loans, net (¹) 11,601 — — 11,601 Total $ 18,078 — — 18,078 December 31, 2014 Other real estate owned $ 7,298 — — 7,298 Impaired loans, net (¹) 8,866 — — 8,866 Total $ 16,164 — — 16,164 (¹) Amount is net of a valuation allowance of $0.9 million at June 30, 2015 and $1.6 million at December 31, 2014 as required by ASC 310, “Receivables.” In the case of the bond portfolio, the Company monitors the valuation technique utilized by various pricing agencies to ascertain when transfers between levels have been affected. The nature of the remaining assets and liabilities is such that transfers in and out of any level are expected to be rare. For the six months ended June 30, 2015, there were no transfers between Levels 1, 2 or 3. The table below includes a rollforward of the balance sheet amounts for the six months ended June 30, 2015 and 2014 (including the change in fair value) for financial instruments classified by the Company within Level 3 of the valuation hierarchy for assets and liabilities measured at fair value on a recurring basis. When a determination is made to classify a financial instrument within Level 3 of the valuation hierarchy, the determination is based upon the significance of the unobservable factors to the overall fair value measurement. However, since Level 3 financial instruments typically include, in addition to the unobservable or Level 3 components, observable components (that is, components that are actively quoted and can be validated to external sources), the gains and losses in the table below include changes in fair value due in part to observable factors that are part of the valuation methodology (in thousands): For the Six Months Ended June 30, 2015 2014 Other Other Other Other Assets Liabilities Assets Liabilities Fair value, January 1 $ 17,331 — $ 11,390 — Total realized gains included in income 558 — 186 — Change in unrealized gains/losses included in other comprehensive income for assets and liabilities still held at June 30 — — — — Purchases, issuances and settlements, net 7,654 — 5,000 — Transfers out of Level 3 — — — — Fair value, June 30 $ 25,543 — $ 16,576 — Total realized gains included in income related to financial assets and liabilities still on the consolidated balance sheet at June 30 $ 558 — 186 — The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments that are not measured at fair value. In cases where quoted market prices or observable components are not available, fair values are based on estimates using discounted cash flow models. Those models are significantly affected by the assumptions used, including the discount rates, estimates of future cash flows and borrower creditworthiness. The fair value estimates presented herein are based on pertinent information available to management as of June 30, 2015 and December 31, 2014. Such amounts have not been revalued for purposes of these consolidated financial statements since those dates and, therefore, current estimates of fair value may differ significantly from the amounts presented herein. Held-to-maturity securities Loans For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values approximate carrying values. Fair values for impaired loans are estimated using discounted cash flow models or based on the fair value of the underlying collateral. For other loans, fair values are estimated using discounted cash flow models, using current market interest rates offered for loans with similar terms to borrowers of similar credit quality. The values derived from the discounted cash flow approach for each of the above portfolios are then further discounted to incorporate credit risk to determine the exit price. Deposits and Securities sold under agreements to repurchase Off-Balance Sheet Instruments The following table presents the carrying amounts, estimated fair value and placement in the fair valuation hierarchy of the Company’s financial instruments at June 30, 2015 and December 31, 2014. This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and cash equivalents, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization.

Loans	Loans — Loans are charged off when management believes that the full collectability of the loan is unlikely. As such, a loan may be partially charged-off after a “confirming event” has occurred which serves to validate that full repayment pursuant to the terms of the loan is unlikely. Loans are placed on nonaccrual status when there is a significant deterioration in the financial condition of the borrower, which often is determined when the principal or interest is more than 90 days past due, unless the loan is both well-secured and in the process of collection. Generally, all interest accrued but not collected for loans that are placed on nonaccrual status, is reversed against current income. Interest income is subsequently recognized only to the extent cash payments are received while the loan is classified as nonaccrual, but interest income recognition is reviewed on a case-by-case basis. A nonaccrual loan is returned to accruing status once the loan has been brought current and collection is reasonably assured or the loan has been “well-secured” through other techniques. Past due status is determined based on the contractual due date per the underlying loan agreement. All loans that are placed on nonaccrual are further analyzed to determine if they should be classified as impaired loans. At December 31, 2014 and at June 30, 2015, there were no loans classified as nonaccrual that were not also deemed to be impaired except for those loans not individually evaluated for impairment as described below. A loan is considered to be impaired when it is probable the Company will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan. This determination is made using a variety of techniques, which include a review of the borrower’s financial condition, debt-service coverage ratios, global cash flow analysis, guarantor support, other loan file information, meetings with borrowers, inspection or reappraisal of collateral and/or consultation with legal counsel as well as results of reviews of other similar industry credits (e.g. builder loans, development loans, church loans, etc). Prior to January 1, 2015, loans with an identified weakness and principal balance of $100,000 or more were subject to individual identification for impairment. During the first quarter of 2015, the Company increased the threshold for identification of individually impaired loans to $500,000, based on regulatory developments, continued improvement in loan quality trends and ratios and strengthening local economies in which the Company operates. Management believes that increasing the threshold will not materially impact the calculation of the allowance for loan losses. Individually identified impaired loans are measured based on the present value of expected payments using the loan’s original effective rate as the discount rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. If the recorded investment in the impaired loan exceeds the measure of fair value, a specific valuation allowance is established as a component of the allowance for loan losses or, in the case of collateral dependent loans, the excess may be charged off. Changes to the valuation allowance are recorded as a component of the provision for loan losses. Any subsequent adjustments to present value calculations for impaired loan valuations as a result of the passage of time, such as changes in the anticipated payback period for repayment, are recorded as a component of the provision for loan losses. For loans less than $500,000, the Company assigns a valuation allowance to these loans utilizing an allocation rate equal to the allocation rate calculated for non-impaired loans of a similar type greater than $500,000 and for homogeneous pools of loans collectively evaluated.
Allowance for Loan Losses	Allowance for Loan Losses — In assessing the adequacy of the allowance, we also consider the results of our ongoing independent loan review process. We undertake this process both to ascertain whether there are loans in the portfolio whose credit quality has weakened over time and to assist in our overall evaluation of the risk characteristics of the entire loan portfolio. Our loan review process includes the judgment of management, independent loan reviewers, and reviews that may have been conducted by third-party reviewers. We incorporate relevant loan review results in the loan impairment determination. In addition, regulatory agencies, as an integral part of their examination process, will periodically review the Company’s allowance for loan losses, and may require the Company to record adjustments to the allowance based on their judgment about information available to them at the time of their examinations.

Summary of Loan Portfolio by Risk Rating	The following summary presents our loan balances by primary loan classification and the amount classified within each risk rating category. Pass rated loans include all credits other than those included in special mention, substandard and doubtful which are defined as follows: • Special mention loans have 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 Bank’s credit position at some future date. • Substandard loans are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize liquidation of the debt. Substandard loans are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. • Doubtful loans have all the characteristics of substandard loans 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. The Bank considers all doubtful loans to be impaired and places the loan on nonaccrual status.

Changes in Fair Value Due to Observable Factors	The table below includes a rollforward of the balance sheet amounts for the six months ended June 30, 2015 and 2014 (including the change in fair value) for financial instruments classified by the Company within Level 3 of the valuation hierarchy for assets and liabilities measured at fair value on a recurring basis. When a determination is made to classify a financial instrument within Level 3 of the valuation hierarchy, the determination is based upon the significance of the unobservable factors to the overall fair value measurement. However, since Level 3 financial instruments typically include, in addition to the unobservable or Level 3 components, observable components (that is, components that are actively quoted and can be validated to external sources), the gains and losses in the table below include changes in fair value due in part to observable factors that are part of the valuation methodology (in thousands): For the Six Months Ended June 30, 2015 2014 Other Other Other Other Assets Liabilities Assets Liabilities Fair value, January 1 $ 17,331 — $ 11,390 — Total realized gains included in income 558 — 186 — Change in unrealized gains/losses included in other comprehensive income for assets and liabilities still held at June 30 — — — — Purchases, issuances and settlements, net 7,654 — 5,000 — Transfers out of Level 3 — — — — Fair value, June 30 $ 25,543 — $ 16,576 — Total realized gains included in income related to financial assets and liabilities still on the consolidated balance sheet at June 30 $ 558 — 186 —
Carrying Value and Estimated Fair Value of Financial Instruments	The following table presents the carrying amounts, estimated fair value and placement in the fair valuation hierarchy of the Company’s financial instruments at June 30, 2015 and December 31, 2014. This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and cash equivalents, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization.
