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, 2014, was derived from audited consolidated financial statements, but does not include all disclosures contained in the Company’s 2014 Form 10-K.

Management’s OTTI evaluation included the use of independently generated third-party credit surveillance reports that analyze the credit characteristics of 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 aggregate amount of credit-related OTTI at the beginning and end of the periods presented along with the amounts recognized in earnings during the three and six months ended June 30, 2015, and 2014: Three months ended Six months ended June 30, June 30, 2015 2014 2015 2014 Balance, beginning of period: $ 227 $ 227 $ 227 $ 227 Additions: Initial OTTI credit loss 13 — 13 — Balance, end of period: $ 240 $ 227 $ 240 $ 227 At June 30, 2015, six of the Company’s private-label mortgage-backed securities with an amortized cost of $1,702 were classified as substandard as their underlying credit was considered impaired.

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 of 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: June 30, % of Gross December 31, % of Gross June 30, % of Gross 2015 Loans 2014 Loans 2014 Loans Real estate loans Multi-family residential $ 68,289 5.23 % $ 51,586 4.93 % $ 50,867 4.93 % Residential 1-4 family 57,112 4.37 % 47,222 4.51 % 46,287 4.49 % Owner-occupied commercial 346,065 26.50 % 259,805 24.84 % 255,562 24.78 % Nonowner-occupied commercial 275,077 21.06 % 201,558 19.27 % 182,141 17.66 % Total permanent real estate loans 746,543 57.16 % 560,171 53.55 % 534,857 51.86 % Construction loans Multi-family residential 6,590 0.50 % 8,472 0.81 % 19,539 1.89 % Residential 1-4 family 30,145 2.31 % 28,109 2.69 % 33,951 3.29 % Commercial real estate 31,659 2.42 % 18,595 1.78 % 28,019 2.72 % Commercial bare land and acquisition & development 15,870 1.22 % 12,159 1.16 % 11,096 1.08 % Residential bare land and acquisition & development 7,074 0.54 % 6,632 0.63 % 6,240 0.61 % Total construction real estate loans 91,338 6.99 % 73,967 7.07 % 98,845 9.59 % Total real estate loans 837,881 64.15 % 634,138 60.62 % 633,702 61.45 % Commercial loans 459,458 35.18 % 406,568 38.87 % 392,810 38.10 % Consumer loans 3,783 0.29 % 3,862 0.37 % 3,410 0.33 % Other loans 5,025 0.38 % 1,443 0.14 % 1,207 0.12 % Gross loans 1,306,147 100.00 % 1,046,011 100.00 % 1,031,129 100.00 % Deferred loan origination fees (1,215 ) (990 ) (1,108 ) 1,304,932 1,045,021 1,030,021 Allowance for loan losses (16,013 ) (15,637 ) (15,675 ) Total loans, net of allowance for loan losses and net deferred fees $ 1,288,919 $ 1,029,384 $ 1,014,346 At June 30, 2015, outstanding loans to dental professionals totaled $321,055 and represented 24.58% of total outstanding loans, compared to dental professional loans of $306,391 or 29.29% of total outstanding loans at December 31, 2014, and $302,822 or 29.37% of total outstanding loans at June 30, 2014. 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, 2015, 64.15% 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, 2015, and 2014 is as follows: Three months ended Six months ended June 30, June 30, 2015 2014 2015 2014 Balance, beginning of period $ 15,724 $ 15,394 $ 15,637 $ 15,917 Provision charged to income 550 — 550 — Loans charged against allowance (454 ) (30 ) (527 ) (631 ) Recoveries credited to allowance 193 311 353 389 Balance, end of period $ 16,013 $ 15,675 $ 16,013 $ 15,675 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: For the three months ended June 30, 2015 Commercial Real Estate Construction Consumer Unallocated Total Beginning balance $ 5,550 $ 7,537 $ 1,062 $ 52 $ 1,523 $ 15,724 Charge-offs (454 ) — — — — (454 ) Recoveries 183 3 3 4 — 193 Provision (reclassification) 622 124 46 (4 ) (238 ) 550 Ending balance $ 5,901 $ 7,664 $ 1,111 $ 52 $ 1,285 $ 16,013 For the six months ended June 30, 2015 Commercial Real Estate Construction Consumer Unallocated Total Beginning balance $ 5,733 $ 7,494 $ 1,077 $ 54 $ 1,279 $ 15,637 Charge-offs (485 ) (42 ) — — — (527 ) Recoveries 287 48 8 10 — 353 Provision (reclassification) 366 164 26 (12 ) 6 550 Ending balance $ 5,901 $ 7,664 $ 1,111 $ 52 $ 1,285 $ 16,013 At June 30, 2015, the allowance for loan losses on dental loans was $4,080 compared to $4,141 at December 31, 2014 and $4,136 at June 30, 2014. See Note 4 for additional information on the dental loan portfolio.

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 Special Mention Substandard Doubtful 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. The following tables present the Company’s loan portfolio information by loan type and credit grade at June 30, 2015, December 31, 2014, and June 30, 2014: Credit Quality Indicators As of June 30, 2015 Loan Grade Pass Special Mention Substandard Doubtful Totals Real estate loans Multi-family residential $ 66,793 $ — $ 1,496 $ — $ 68,289 Residential 1-4 family 49,551 — 7,561 — 57,112 Owner-occupied commercial 334,002 — 12,063 — 346,065 Nonowner-occupied commercial 270,739 — 4,338 — 275,077 Total real estate loans 721,085 — 25,458 — 746,543 Construction Multi-family residential 6,590 — — — 6,590 Residential 1-4 family 30,073 — 72 — 30,145 Commercial real estate 30,512 — 1,147 — 31,659 Commercial bare land and acquisition & development 15,586 — 284 — 15,870 Residential bare land and acquisition & development 6,592 — 482 — 7,074 Total construction loans 89,353 — 1,985 — 91,338 Commercial and other 450,918 — 13,565 — 464,483 Consumer 3,782 — 1 — 3,783 Totals $ 1,265,138 $ — $ 41,009 $ — $ 1,306,147 Credit Quality Indicators As of December 31, 2014 Loan Grade Pass Special Mention Substandard Doubtful Totals Real estate loans Multi-family residential $ 50,074 $ — $ 1,512 $ — $ 51,586 Residential 1-4 family 39,527 — 7,695 — 47,222 Owner-occupied commercial 254,166 — 5,639 — 259,805 Nonowner-occupied commercial 197,940 — 3,618 — 201,558 Total real estate loans 541,707 — 18,464 — 560,171 Construction Multi-family residential 8,472 — — — 8,472 Residential 1-4 family 28,109 — — — 28,109 Commercial real estate 17,645 — 950 — 18,595 Commercial bare land and acquisition & development 11,917 — 242 — 12,159 Residential bare land and acquisition & development 5,954 — 678 — 6,632 Total construction loans 72,097 — 1,870 — 73,967 Commercial and other 395,918 — 12,093 — 408,011 Consumer 3,854 — 8 — 3,862 Totals $ 1,013,576 $ — $ 32,435 $ — $ 1,046,011 Credit Quality Indicators As of June 30, 2014 Loan Grade Pass Special Mention Substandard Doubtful Totals Real estate loans Multi-family residential $ 49,341 $ — $ 1,526 $ — $ 50,867 Residential 1-4 family 38,453 — 7,834 — 46,287 Owner-occupied commercial 244,255 4,219 7,088 — 255,562 Nonowner-occupied commercial 178,168 — 3,973 — 182,141 Total real estate loans 510,217 4,219 20,421 — 534,857 Construction Multi-family residential 19,539 — — — 19,539 Residential 1-4 family 33,951 — — — 33,951 Commercial real estate 28,019 — — — 28,019 Commercial bare land and acquisition & development 10,866 — 230 — 11,096 Residential bare land and acquisition & development 5,487 — 753 — 6,240 Total construction loans 97,862 — 983 — 98,845 Commercial and other 380,601 — 13,416 — 394,017 Consumer 3,398 — 12 — 3,410 Totals $ 992,078 $ 4,219 $ 34,832 $ — $ 1,031,129 At June 30, 2015, December 31, 2014, and June 30, 2014, the Company had $1,077, $562 and $417, 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.

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.

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, 2015, December 31, 2014, and June 30, 2014: June 30, 2015 Troubled Debt Restructurings as of June 30, 2014 Number of Post-Modification Outstanding Recorded Number of Contracts Post-Modification Number of Contracts Post-Modification Real estate Multifamily residential — $ — — $ — — $ — Residential 1-4 family 6 701 7 768 7 795 Owner-occupied commercial 2 1,027 2 1,046 5 1,988 Non owner-occupied commercial 7 2,408 7 2,503 3 2,309 Total real estate loans 15 4,136 16 4,317 15 5,092 Construction Multifamily residential — — — — — — Residential 1-4 family — — — — — — Commercial real estate — — — — — — Commercial bare land and acquisition & development — — — — — — Residential bare land and acquisition & development — — — — — — Total construction loans — — — — — — Commercial and other 11 1,941 12 2,259 11 2,553 Consumer — — — — — — Total 26 $ 6,077 28 $ 6,576 26 $ 7,645 The recorded investment in TDRs on nonaccrual status totaled $1,730, $1,649, and $2,260 at June 30, 2015, December 31, 2014, and June 30, 2014, 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, 2015, the Company identified no TDRs that were newly considered impaired for which impairment was previously measured under the Company’s general loan loss allowance methodology. The types of modifications offered can generally be described in the following categories: Rate Modification - Term Modification - Interest-only Modification - Combination Modification - There were no newly restructured loans identified in the six months ended June 30, 2015. Below is a table of the newly restructured loans identified in the six months ended June 30, 2014.

In such cases of default, the Company takes appropriate action to recover principal and interest payments including the use of foreclosure proceedings. There were no TDRs that subsequently defaulted within the first twelve months of restructure during the periods ended June 30, 2015 and 2014. At June 30, 2015, December 31, 2014, and June 30, 2014, the Company had no commitments to lend additional funds on loans restructured as TDRs.

Dental Loan Portfolio	NOTE 4 – DENTAL LOAN PORTFOLIO Dental lending is not operated as a business segment, and dental loans are made in the normal course of commercial lending activities throughout the Company. However, 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, 2015, December 31, 2014, and June 30, 2014, loans to dental professionals totaled $321,055, $306,391, and $302,822, respectively, and represented 24.58%, 29.29% and 29.37% in principal amount of total outstanding loans, respectively. As of June 30, 2015, December 31, 2014, and June 30, 2014, the dental loans were supported by government guarantees totaling $11,442, $12,700 and $13,967, respectively. These guarantees represented 3.56%, 4.15% and 4.61% 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. Loan Classification Major classifications of dental loans at June 30, 2015, December 31, 2014, and June 30, 2014, were as follows: June 30, December 31, June 30, 2014 Real estate secured loans: Owner-occupied commercial $ 59,819 $ 60,092 $ 61,452 Other dental real estate loans 2,596 2,785 2,663 Total permanent real estate loans 62,415 62,877 64,115 Dental construction loans 2,033 604 388 Total real estate loans 64,448 63,481 64,503 Commercial loans 256,607 242,910 238,319 Gross loans $ 321,055 $ 306,391 $ 302,822 Market Area The Bank’s defined “local market area” is within the states of Oregon and Washington, west of the Cascade Mountain Range. This area is serviced by branch locations in Eugene, Oregon; Portland, Oregon; and Seattle, Washington. The Company also makes national dental loans throughout the United States. National loan relationships are maintained and serviced by Bank personnel primarily located in Portland. The following table summarizes the Company’s dental lending by borrower location: June 30, December 31, June 30, 2014 Local $ 156,315 $ 159,425 $ 169,102 National 164,740 146,966 133,720 Total $ 321,055 $ 306,391 $ 302,822 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.

Federal Home Loan Bank Borrowings	NOTE 6 – FEDERAL HOME LOAN BANK BORROWINGS The Company has a borrowing limit with the Federal Home Loan Bank of Des Moines (“FHLB”) equal to 35% of total assets, subject to the value of discounted collateral pledged. On June 1, 2015, the FHLB Des Moines announced the completion of its merger with the FHLB Seattle effective May 31, 2015. At that time, the combined entity repurchased excess stock above what was needed to support borrowings, resulting in a reduction of outstanding FHLB stock. At June 30, 2015, the maximum borrowing line was $640,830; however, the FHLB borrowing line was limited by the discounted value of collateral pledged. At June 30, 2015, the Company had pledged $604,157 in real estate loans to the FHLB that had a discounted value of $400,600. There was $84,000 borrowed on this line at June 30, 2015. At December 31, 2014, the maximum FHLB borrowing line was $451,298, and the Company had pledged real estate loans and securities to the FHLB with a discounted value of $318,854. There was $96,000 borrowed on this line at December 31, 2014. At June 30, 2014, the maximum FHLB borrowing line was $449,629, and the Company had pledged real estate loans and securities to the FHLB with a discounted collateral value of $284,453.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
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 stock 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, 2015, 19,185 restricted shares were granted and issued to directors with no restrictions imposed. Additionally, 155,898 RSUs were granted to employees during the first six months of 2015. Of the 155,898 RSUs granted, 7,052 cliff vest on January 1, 2019, 148,460 vest over four years, and 386 vested immediately. Shares of common stock will be issued as soon as practicable upon vesting. 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. No other awards were granted during the six months ended June 30, 2015 and 2014. The following table summarizes the shares and the aggregate grant-date fair market values of the equity-based awards granted during the six months ended June 30, 2015: Six months ended June 30, 2015 June 30, 2014 Shares Grant Date Shares Grant Date Equity-based awards: Director restricted stock 19,185 $ 248 14,996 $ 200 Employee stock options — — — — Employee stock SARs — — — — Employee RSUs 155,898 2,206 127,051 1,679 175,083 $ 2,454 142,047 $ 1,879 The following table provides a summary of the Company’s RSU activity, including the weighted average grant date fair value per share, for the six months ended June 30, 2015: Six months ended June 30, 2015 Non-Vested Weighted Average Balance, beginning of period $ 306,532 $ 11.18 Granted 155,898 13.00 Vested shares issued (75,373 ) 10.59 Vested shares surrendered for taxes (46,105 ) 10.59 Forfeited or expired (4,847 ) 11.86 Balance, end of period $ 336,105 $ 12.23 The following table identifies the compensation expense recorded and tax benefits received by the Company on its share-based compensation plans for the three and six months ended June 30, 2015, and 2014: Three months ended June 30, 2015 2014 Compensation Expense (Income) Tax Benefit (expense) Compensation Expense Tax Benefit Equity-based awards: Director restricted stock $ 248 $ 94 $ 200 $ 76 Employee RSUs 376 143 331 126 Liability-based awards: Employee cash SARs (50 ) (19 ) 15 6 $ 574 $ 218 $ 546 $ 208 Six months ended June 30, 2015 2014 Compensation Tax Benefit Compensation Tax Benefit Equity-based awards: Director restricted stock $ 248 $ 94 $ 200 $ 76 Employee stock options — — 13 — Employee stock SARs — — 26 10 Employee RSUs 708 269 561 213 Liability-based awards: Employee cash SARs (50 ) (19 ) 70 27 $ 906 $ 344 $ 870 $ 326 The following table identifies stock options, employee stock SARs, and employee cash SARs exercised during the three and six months ended June 30, 2015: Three months ended June 30, 2015 Number Exercised Weighted Average Exercise Price Intrinsic Value Number of Issued Net Cash Payment to Employees Stock options — $ — $ — — NA Employee stock SARs 600 $ 11.30 $ 1 52 NA Employee cash SARs — $ — NA NA $ — Six months ended June 30, 2015 Number Weighted Intrinsic Number of Net Cash Stock options 1,102 $ 12.25 $ 2 1,102 NA Employee stock SARs 1,213 $ 11.50 $ 1 92 NA Employee cash SARs 208 $ 12.07 NA NA $ — The following table identifies stock options, employee stock SARs, and employee cash SARs exercised during the three and six months ended June 30, 2014: Three months ended June 30, 2014 Number Weighted Intrinsic Number of Net Cash Stock options — $ — $ — — NA Employee stock SARs 1,961 $ 11.53 $ 3 189 NA Employee cash SARs 2,219 $ 12.07 NA NA $ 3 Six months ended June 30, 2014 Number Weighted Intrinsic Number of Net Cash Stock options 16,779 $ 11.29 $ 57 — NA Employee stock SARs 14,140 $ 11.86 $ 25 1,629 NA Employee cash SARs 6,445 $ 12.21 NA NA $ 8 No liability-based or equity-based awards vested during the six months ended June 30, 2014.

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, 2015, December 31, 2014, and June 30, 2014: Carrying Fair Value at June 30, 2015 Level 1 Level 2 Level 3 Financial assets: Cash and cash equivalents $ 39,602 $ 39,602 $ — $ — Loans 1,304,932 — — 1,289,072 Federal Home Loan Bank stock 5,468 5,468 — — Interest receivable 5,833 5,833 — — Financial liabilities: Deposits $ 1,514,181 $ — $ 1,514,255 $ — Federal funds and overnight funds purchased 5,500 5,500 — — Federal Home Loan Bank borrowings 84,000 — 84,587 — Junior subordinated debentures 8,248 — 2,494 — Interest payable 170 170 — — Carrying Fair Value at December 31, 2014 Level 1 Level 2 Level 3 Financial assets: Cash and cash equivalents $ 25,787 $ 25,787 $ — $ — Loans 1,045,021 — — 1,033,254 Federal Home Loan Bank stock 10,019 10,019 — — Interest payable 4,773 4,773 — — Financial liabilities: Deposits $ 1,209,093 $ — $ 1,209,240 $ — Federal funds and overnight funds purchased — — — — Federal Home Loan Bank borrowings 96,000 — 96,721 — Junior subordinated debentures 8,248 — 2,410 — Interest payable 176 176 — — Carrying Fair Value at June 30, 2014 Level 1 Level 2 Level 3 Financial assets: Cash and cash equivalents $ 43,443 $ 43,443 $ — $ — Loans 1,030,021 — — 1,015,721 Federal Home Loan Bank stock 10,227 10,227 — — Interest payable 5,101 5,101 — — Financial liabilities: Deposits $ 1,132,654 $ — $ 1,132,917 $ — Federal funds and overnight funds purchased 6,410 6,410 — — Federal Home Loan Bank borrowings 164,500 — 165,502 — Junior subordinated debentures 8,248 — 2,326 — Interest payable 170 170 — — The tables below show assets measured at fair value on a recurring basis as of June 30, 2015, December 31, 2014, and June 30, 2014: Carrying Fair Value at June 30, 2015 Value Level 1 Level 2 Level 3 Available-for-sale securities Obligations of U.S. government agencies $ 55,796 $ — $ 55,796 $ — Obligations of states and political subdivisions 87,387 — 87,387 — Mortgage-backed securities 202,114 — 202,114 — Private-label mortgage-backed securities 3,334 — 1,551 1,783 SBA pools 34,089 — 34,089 — Corporate securities 898 — 898 — Swap derivative 117 117 — — Total assets measured on a recurring basis $ 383,735 $ 117 $ 381,835 $ 1,783 Carrying Fair Value at December 31, 2014 Value Level 1 Level 2 Level 3 Available-for-sale securities Obligations of U.S. government agencies $ 39,185 $ — $ 39,185 $ — Obligations of states and political subdivisions 83,981 — 83,981 — Mortgage-backed securities 205,390 — 205,390 — Private-label mortgage-backed securities 3,816 — 2,248 1,568 SBA pools 19,574 — 19,574 — Swap derivative 176 176 — — Total assets measured on a recurring basis $ 352,122 $ 176 $ 350,378 $ 1,568 Fair Value at June 30, 2014 Value Level 1 Level 2 Level 3 Available-for-sale securities Obligations of U.S. government agencies $ 37,162 $ — $ 37,162 $ — Obligations of states and political subdivisions 81,680 — 81,680 — Mortgage-backed securities 212,720 — 212,720 — Private-label mortgage-backed securities 4,443 — 2,750 1,693 SBA pools 8,640 — 8,640 — Swap derivative 218 218 — — Total assets measured on a recurring basis $ 344,863 $ 218 $ 342,952 $ 1,693 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, 2015, and 2014, or during the year ended December 31, 2014. 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 it 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 private-label mortgage-backed securities measured at fair value on a recurring basis using unobservable inputs (Level 3) for the three and six months ended June 30, 2015, and 2014: Three months ended Six months ended 2015 2014 2015 2014 Beginning balance $ 1,545 $ 1,774 $ 1,568 $ 1,786 Transfers from level 2 300 — 300 — Transfers out of Level 3 — — — — Total gains or losses Included in earnings (13 ) — (13 ) — Included in other comprehensive income 29 (61 ) 68 (11 ) Paydowns (78 ) (20 ) (140 ) (82 ) Purchases, issuances, sales and settlements Purchases — — — — Issuances — — — — Sales — — — — Settlements — — — — Ending balance $ 1,783 $ 1,693 $ 1,783 $ 1,693 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 • Obligations of states and political subdivisions • Private-label mortgage-backed securities • Mortgage-backed securities • SBA variable pools 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 • Obligations of states and political subdivisions • Private-label mortgage-backed securities • Mortgage-backed securities • SBA pools 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, 2015, 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. During second quarter 2015, there was one security that transferred from level 2 to level 3 as the bank recorded OTTI on a security. For additional information, see Note 2 of the Notes to Consolidated Financial Statements There have been no significant changes in the valuation techniques during the periods reported. The tables below show assets measured at fair value on a nonrecurring basis as of June 30, 2015, December 31, 2014, and June 30, 2014: Carrying Fair Value June 30, 2015 Value Level 1 Level 2 Level 3 Loans measured for impairment (net of government guarantees and specific reserves) $ 3,041 $ — $ — $ 3,041 Other real estate owned 12,666 — — 12,666 Total $ 15,707 $ — $ — $ 15,707 Carrying Fair Value December 31, 2014 Value Level 1 Level 2 Level 3 Loans measured for impairment (net of government guarantees and specific reserves) $ 3,110 $ — $ — $ 3,110 Other real estate owned 13,374 — — 13,374 Total $ 16,484 $ — $ — $ 16,484 Carrying Fair Value June 30, 2014 Value Level 1 Level 2 Level 3 Loans measured for impairment (net of government guarantees and specific reserves) $ 5,298 $ — $ — $ 5,298 Other real estate owned 11,531 — — 11,531 Total $ 16,829 $ — $ — $ 16,829 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 and Hedging Activities Disclosure [Abstract]
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, 2015, was a $117 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, 2015, 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.

Banking and Thrift [Abstract]
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. In July 2013, the Federal Reserve Board and the other U.S. federal banking agencies adopted final rules making significant changes to the U.S. regulatory capital framework for U.S. banking organizations and to conform this framework to the Basel Committee’s current international regulatory capital accord (Basel III). These rules were effective January 1, 2015 and replaced the federal banking agencies’ general risk-based capital rules, advanced approaches rule, market-risk rule, and leverage rules, in accordance with certain transition provisions. The new rules implement higher minimum capital requirements, include a new common equity Tier 1 capital requirement, and establish criteria that instruments must meet in order to be considered common equity Tier 1 capital, additional Tier 1 capital, or Tier 2 capital. When fully phased in, the final rules will provide for increased minimum capital ratios as follows: (a) a common equity Tier 1 capital ratio of 4.50%; (b) a Tier 1 capital ratio of 6.00% (which is an increase from 4.00%); (c) a total capital ratio of 8.00%; and (d) a Tier 1 leverage ratio to average consolidated assets of 4.00%. The new rules permit depository institution holding companies with less than $15 billion in total consolidated assets as of December 31, 2009, such as the Company, to include trust preferred securities in Tier 1 capital. The new rules made it optional for banks and bank holding companies to include accumulated other comprehensive income in their calculations of Tier 1 capital. The Company’s accumulated other comprehensive income consists primarily of the unrealized gain or loss on the securities portfolio as a result of marking securities available-for-sale to market. The Company opted to exclude accumulated other comprehensive income from its calculation of Tier 1 capital. Overall, the new rules did not materially impact the Company’s reported capital ratios for first or second quarter 2015. The Company continues to evaluate the impact of the rules as they are phased in over the next few years. 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, 2015, the Company and the Bank met all capital adequacy requirements to which they are subject. As of June 30, 2015, 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.

Organization, Consolidation and Presentation of Financial Statements [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, 2014, was derived from audited consolidated financial statements, but does not include all disclosures contained in the Company’s 2014 Form 10-K. The interim consolidated financial statements should be read in conjunction with the December 31, 2014, consolidated financial statements, including the notes thereto, included in the Company’s 2014 Form 10-K.
Loans	Loans are stated at the amount of unpaid principal net of loan premiums or discounts for purchased loans, net of 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.
