Accounting Pronouncements Recently Issued or Adopted [Abstract]
Accounting Pronouncements Recently Issued or Adopted	Note 2 – Accounting Pronouncements Recently Issued or Adopted In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which creates Topic 606 and supersedes Topic 605, Revenue Recognition. In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606), which postponed the effective date of 2014-09. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net, which amended the principal versus agent implementation guidance set for in ASU 2014-09. Among other things, ASU 2016-08 clarifies that an entity should evaluate whether it is the principal or the agent for each specified good or service promised in a contract with a customer. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. The ASU amends certain aspects of the guidance set forth in the FASB's new revenue standard related to identifying performance obligations and licensing implementation. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In general, the new ASU requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which provides clarifying guidance in certain narrow areas and adds some practical expedients, but does not change the core revenue recognition principle in Topic 606. This ASU is effective for interim and annual periods beginning after December 15, 2017; early adoption is not permitted. For financial reporting purposes, the ASU allows for either full retrospective adoption, meaning this ASU is applied to all of the periods presented, or modified retrospective adoption, meaning the ASU is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the ASU recognized at the date of initial application. As a financial institution, the Company's largest component of revenue, interest income, is excluded from the scope of this ASU. Accordingly, the adoption of ASU No. 2014-09 is not expected to have a material impact on the Company’s consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. The new guidance is intended to improve the recognition and measurement of financial instruments. This ASU requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. In addition, the ASU requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. This ASU also eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. The ASU also requires a reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument specific credit risk (also referred to as “own credit”) when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. ASU No. 2016-01 is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted for certain provisions. The Company is currently evaluating the impact of this ASU on the Company's consolidated financial statements. In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842). ASU No. 2016-02 requires lessees to recognize, on the balance sheet, the assets and liabilities arising from operating leases. A lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. A lessee should include payments to be made in an optional period only if the lessee is reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease. For a finance lease, interest payments should be recognized separately from amortization of the right-of-use asset in the statement of comprehensive income. For operating leases, the lease cost should be allocated over the lease term on a generally straight-line basis. The amendments in ASU 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments in the ASU is permitted. Although an estimate of the impact of the new leasing standard has not yet been determined, once adopted, we expect to report higher assets and liabilities as a result of including right-of-use assets and lease liabilities related to certain banking offices and certain equipment under noncancelable operating lease agreements, however, based on current leases the adoption is not expected to have a material impact on the Company’s consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU replaces the existing incurred loss impairment methodology that recognizes credit losses when a probable loss has been incurred with new methodology where loss estimates are based upon lifetime expected credit losses. The amendments in this ASU require a financial asset that is measured at amortized cost to be presented at the net amount expected to be collected. The income statement would then reflect the measurement of credit losses for newly recognized financial assets as well as changes to the expected credit losses that have taken place during the reporting period. The measurement of expected credit losses will be based on historical information, current conditions, and reasonable and supportable forecasts that impact the collectability of the reported amount. Available-for-sale securities will bifurcate the fair value mark and establish an allowance for credit losses through the income statement for the credit portion of that mark. The interest portion will continue to be recognized through accumulated other comprehensive income or loss. The change in allowance recognized as a result of adoption will occur through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019 with early adoption permitted after December 15, 2018. The Company has begun the process to implement this new standard by working with a vendor that specializes in this area. While the Company has not quantified the impact of this ASU, it does expect changing from the current incurred loss model to an expected loss model will result in an earlier recognition of losses. The Company also expects that once adopted the allowance for loan losses will increase, however, until its evaluation is complete the magnitude of the increase will be unknown. In August 2016, FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses the appropriate classification of eight specific cash flow issues on the cash flow statement. Debt prepayment costs should be classified as an outflow for financing activities. Settlement of zero-coupon debt instruments divides the interest portion as an outflow for operating activities and the principal portion as an outflow for financing activities. Contingent consideration payments made after a business combination should be classified as outflows for financing and operating activities. Proceeds from the settlement of bank-owned life insurance policies should be classified as inflows from investing activities. Other specific areas are identified in the ASU as to the appropriate classification of the cash inflows or outflows. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted and must be applied using a retrospective transition method to each period presented. The Company does not expect this ASU to have a material impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20). ASU 2017-08 is intended to amend the amortization period for certain purchased callable debt securities held at a premium. Under ASU 2017-08, the FASB is shortening the amortization period for the premium to the earliest call date. Under current GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the instrument. ASU 2017-08 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. The Company is reviewing its securities portfolio to assess the impact the adoption of this ASU will have on the Company’s consolidated financial statements but does not expect this ASU to have a material impact. In May 2017, the FASB issued ASU No. 2017-09, Compensation--Stock Compensation (Topic 718): Scope of Modification Accounting

At December 31, 2016, three municipal securities were in an unrealized loss position for less than 12 months and one agency security was in a loss position for over 12 months. All of the agency mortgage-backed securities in an unrealized loss position at June 30, 2017 and December 31, 2016 were issued or guaranteed by U.S. governmental agencies. The unrealized losses were caused by changes in market interest rates or the widening of market spreads subsequent to the initial purchase of these securities, and not related to the underlying credit of the issuers or the underlying collateral. It is expected that these securities will not be settled at a price less than the amortized cost of each investment. Because the decline in fair value is attributable to changes in interest rates or widening market spreads and not credit quality, and because we do not intend to sell the securities in this class and it is not likely that we will be required to sell these securities before recovery of their amortized cost basis, which may include holding each security until contractual maturity, the unrealized losses on these investments are not considered an other-than-temporary impairment (“OTTI”) during the three and six months ended June 30, 2017 or the year ended December 31, 2016. As of June 30, 2017 and December 31, 2016, one non-agency mortgage-backed security was in an unrealized loss position for over 12 months. The unrealized loss was caused by changes in interest rates causing a decline in the fair value subsequent to the purchase. The contractual terms of this investment do not permit the issuer to settle the security at a price less than par. Management does not intend to sell this non-agency mortgage-backed security and it is unlikely that the Company will be required to sell this security before recovery of its amortized cost basis. Management’s impairment evaluation indicated that this security possesses qualitative and quantitative factors that do not suggest an OTTI. These factors include, but are not limited to: the length of time and extent of the fair value declines, ratings agency down grades, the potential for an increased level of actual defaults, and the extension in duration of the securities. Based upon the results of the evaluation of the quantitative and qualitative factors, the non-agency mortgage-backed security does not reflect OTTI during the three and six months ended June 30, 2017 or the year ended December 31, 2016.

When we classify problem loans as either substandard or doubtful, we may establish a specific allowance in an amount we deem prudent to address the risk specifically (if the loan is impaired) or we may allow the loss to be addressed in the general allowance (if the loan is not impaired). General allowances represent loss reserves which have been established to recognize the inherent risk associated with lending activities, but which, unlike specific allowances, have not been specifically allocated to particular problem loans. When the Company classifies problem loans as a loss, we charge-off such assets in the period in which they are deemed uncollectible. Assets that do not currently expose us to sufficient risk to warrant classification as substandard, doubtful or loss, but possess identified weaknesses, are classified as either watch or special mention assets. Our determination as to the classification of our assets and the amount of our valuation allowances is subject to review by the Federal Deposit Insurance Corporation (“FDIC”), the Bank’s federal regulator, and the Washington Department of Financial Institutions (“WDFI”), the Bank’s state banking regulator, which can order the establishment of additional loss allowances. Pass rated loans are loans that are not otherwise classified or criticized.

Rate Modification Term Modification Payment Modification Combination Modification There was one $1.3 million one- to four- family residential loan modified as a TDR during the six months ended June 30, 2017. The following TDR loans paid off during the first six months of 2017: a $125,000 one- to four- family residential loan, a $14,000 manufactured home loan, a zero balance home equity loan and a $359,000 commercial/multifamily loan. There were no new TDRs during the six months ended June 30, 2016. There were no post-modification changes for the unpaid principal balance in loans, net of partial charge-offs, that were recorded as a result of the TDRs for the six months ended June 30, 2017 and 2016. There were no TDRs for which there was a payment default within the first 12 months of modification during the six months ended June 30, 2017 or 2016. The Company had no commitments to extend additional credit to borrowers owing receivables whose terms have been modified in TDRs. All TDRs are also classified as impaired loans and are included in the loans individually evaluated for impairment in the calculation of the allowance for loan losses.

The following tables provide a description of the valuation technique, unobservable input, and qualitative information about the unobservable inputs for the Company’s assets and liabilities classified as Level 3 and measured at fair value on a recurring basis at June 30, 2017 and December 31, 2016: June 30, 2017 Financial Instrument Valuation Technique Unobservable Input(s) Range (Weighted-Average) Mortgage Servicing Rights Discounted cash flow Prepayment speed assumption 109-395% (156%) Discount rate 13-15% (13%) Non-agency mortgage-backed securities Discounted cash flow Discount rate 7-9% (8%) December 31, 2016 Financial Instrument Valuation Technique Unobservable Input(s) Range (Weighted-Average) Mortgage Servicing Rights Discounted cash flow Prepayment speed assumption 104-396% (152%) Discount rate 13%-15% (13%) Non-agency mortgage-backed securities Discounted cash flow Discount rate 7%-9% (8%) Generally, any significant increases in the constant prepayment rate and discount rate utilized in the fair value measurement of the mortgage servicing rights will result in a negative fair value adjustment (and decrease in the fair value measurement). Conversely, a decrease in the constant prepayment rate and discount rate will result in a positive fair value adjustment (and increase in the fair value measurement). An increase in the weighted average life assumptions will result in a decrease in the constant prepayment rate and conversely, a decrease in the weighted-average life will result in an increase of the constant prepayment rate.

As a result, the fair values of our financial instruments will change when interest rate levels change, which may be favorable or unfavorable to us. Management attempts to match maturities of assets and liabilities to the extent necessary or possible to minimize interest rate risk. However, borrowers with fixed-rate obligations are less likely to prepay in a rising rate environment and more likely to prepay in a falling rate environment. Conversely, depositors who are receiving fixed-rates are more likely to withdraw funds before maturity in a rising rate environment and less likely to do so in a falling rate environment. Management monitors rates and maturities of assets and liabilities and attempts to minimize interest rate risk by establishing early withdrawal penalties for time deposits, creating interest rate floors for certain variable rate loans, adjusting terms of new loans and deposits, by borrowing at fixed-rates for fixed-terms and investing in securities with terms that mitigate our overall interest rate risk.

Earnings Per Common Share [Abstract]
Earnings Per Common Share	Note 9 – Earnings Per Common Share Basic earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding for the period, reduced for average unallocated ESOP shares and average unvested restricted stock awards. Unvested share-based awards contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method described in ASC 260-10-45-60B. Diluted earnings per common share reflects the potential dilution that could occur if securities or other contracts to issue common stock (such as stock awards and options) were exercised or converted to common stock, or resulted in the issuance of common stock that then shared in the Company’s earnings. Diluted earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding for the period increased for the dilutive effect of unexercised stock options and unvested restricted stock awards. The dilutive effect of the unexercised stock options and unvested restricted stock awards is calculated under the treasury stock method utilizing the average market value of the Company’s stock for the period. Earnings per share are summarized for the periods presented in the following table (in thousands, except per share data): Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Net income $ 1,303 $ 1,254 $ 2,717 $ 2,360 Weighted-average number of shares outstanding, basic 2,501 2,481 2,500 2,479 Effect of potentially dilutive common shares (1) 96 77 100 73 Weighted-average number of shares outstanding, diluted 2,597 2,558 2,600 2,552 Earnings per share, basic $ 0.52 $ 0.51 $ 1.09 $ 0.95 Earnings per share, diluted $ 0.50 $ 0.49 $ 1.04 $ 0.92 (1) There were no anti-dilutive securities at either June 30, 2017 or June 30, 2016.

Stock-based Compensation [Abstract]
Stock-based Compensation	Note 10 – Stock-based Compensation Stock Options and Restricted Stock The Company currently has two existing Equity Incentive Plans, a 2008 Equity Inventive Plan (the “2008 Plan”) and a 2013 Equity Incentive Plan (the “2013 Plan”, and together with the 2008 Plan (the “Plans”)), both of which were approved by shareholders. The Plans permit the grant of restricted stock, restricted stock units, stock options, and stock appreciation rights. Under the 2008 Plan, 126,287 shares of common stock were approved for awards for stock options and stock appreciation rights and 50,514 shares of common stock were approved for awards for restricted stock and restricted stock units. Under the 2013 Plan, 141,750 shares of common stock were approved for awards for stock options and stock appreciation rights and 56,700 shares of common stock were approved for awards for restricted stock and restricted stock units. As of June 30, 2017, on an adjusted basis, awards for stock options totaling 265,799 shares and awards for restricted stock totaling 107,214 shares of Company common stock have been granted, net of any forfeitures, to participants in the Plans. During the three months ended June 30, 2017 and 2016, share-based compensation expense 2016, share-based compensation expense Stock Option Awards The stock option awards granted to date under the 2008 Plan vest in 20 percent annual increments commencing one year from the grant date in accordance with the requirements of the 2008 Plan. The stock option awards granted to date under the 2013 Plan vest in equal annual installments of either two or four years. All of the options granted under the Plans are exercisable for a period of 10 years from the date of grant, subject to vesting. The following is a summary of the Company's stock option award activity during the six months ended June 30, 2017: Shares Weighted- Average Exercise Price Weighted-Average Remaining Contractual Term In Years Aggregate Intrinsic Value Outstanding at January 1, 2017 170,057 $ 15.41 6.44 $ 2,141,018 Granted 32,010 28.34 Exercised (2,135 ) 15.43 Forfeited (602 ) 28.28 Expired - - Outstanding at June 30, 2017 199,330 17.45 6.52 2,599,263 Exercisable 131,770 15.60 5.86 $ 1,962,055 Expected to vest, assuming a 0% forfeiture rate over the vesting term 67,560 $ 21.06 7.81 $ 637,208 As of June 30, 2017, there was $393,000 of total unrecognized compensation cost related to non-vested stock options granted under the Plans. The cost is expected to be recognized over the remaining weighted-average vesting period of 1.8 years. The fair value of each option grant is estimated as of the grant date using the Black-Scholes option-pricing model. The fair value of options granted for the six months ended June 30, 2017 was determined using the following weighted-average assumptions as of the grant date. Annual dividend yield 1.28 % Expected volatility 22.99 % Risk-free interest rate 2.20 % Expected term 6.50 years Weighted-average grant date fair value per option granted $ 6.62 The fair value of options granted for the six months ended June 30, 2016 was determined using the following weighted-average assumptions as of the grant date. Annual dividend yield 1.03 % Expected volatility 25.48 % Risk-free interest rate 1.64 % Expected term 6.92 years Weighted-average grant date fair value per option granted $ 5.78 Restricted Stock Awards The fair value of the restricted stock awards is equal to the fair value of the Company’s stock at the date of grant. Compensation expense is recognized over the vesting period that the awards are based. The restricted stock awards granted to date under the 2008 Plan provide for vesting in 20% annual increments commencing one year from the grant date. The restricted stock awards granted to date under the 2013 Plan provide for immediate vesting of 33.33% of a recipient’s award with the balance of an individual’s award under the 2013 Plan vesting in two equal annual installments commencing one year from the grant date. The following is a summary of the Company’s restricted stock award activity during the six months ended June 30, 2017: Shares Weighted-Average Grant-Date Fair Value Per Share Non-vested at January 1, 2017 26,138 $ 18.08 Granted 576 28.34 Vested (14,929 ) 17.61 Forfeited - - Expired - - Non-vested at June 30, 2017 11,785 19.05 Expected to vest assuming a 0% forfeiture rate over the vesting term 11,785 $ 19.05 As of June 30, 2017, there was $171,000 of unrecognized compensation cost related to non-vested restricted stock granted under the Plans. The cost is expected to be recognized over the weighted-average vesting period of 0.78 years. The total fair value of shares vested for the six months ended June 30, 2017 and 2016 was $430,000 and $345,000, respectively. Employee Stock Ownership Plan In January 2008, the ESOP borrowed $1.2 million from the Company to purchase common stock of the Company. In August 2012, in conjunction with the Company’s conversion to a full stock company from the mutual holding company structure, the ESOP borrowed an additional $1.1 million from the Company to purchase common stock of the Company. Both loans are being repaid by the Bank through contributions to the ESOP over a period of ten years. The interest rate on the loans is fixed at 4.00% and 2.25%, per annum, respectively. As of June 30, 2017, the remaining balances of the ESOP loans were $136,000 and $590,000, respectively. Neither the loan balances nor the related interest expense are reflected on the condensed consolidated financial statements. At June 30, 2017, the ESOP was committed to release 21,443 shares of the Company’s common stock to participants and held 66,800 unallocated shares remaining to be released in future years. The fair value of the 183,469 restricted shares held by the ESOP trust was $5.6 million at June 30, 2017. ESOP compensation expense included in salaries and benefits was $170,000 and $338,000 for the three and six months ended June 30, 2017 and $135,000 and $271,000 for the three and six months ended June 30, 2016, respectively.

Acquisition of Sunwest Bank Branch	Note 11 – Acquisition of Sunwest Bank Branch On June 30, 2017, the Bank completed its acquisition of the University Place branch from Sunwest Bank (“Sunwest”), located at 4922 Bridgeport Way West, University Place, Washington 98467. This branch acquisition was completed under a Purchase and Assumption Agreement between the Company and Sunwest. Under the terms of the agreement, the Bank paid a deposit premium of $485,000 equal to 3.35% of the assumed deposits and acquired the branch lease, certain personal property and records of the former Sunwest branch. The branch acquisition was accounted for as a business combination under the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed and consideration exchanged were recorded at acquisition date fair values. Fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition as additional information regarding the closing date fair values becomes available. The estimated fair value of the assets purchased and liabilities assumed in the acquisition of the University Place Branch on June 30, 2017 are presented in the following table: Fair value of assets acquired: June 30, 2017 Cash and cash equivalents $ 13,671 Loans 24 Premises and equipment 312 Core deposit intangible 155 Goodwill 312 Total fair value of assets acquired $ 14,474 Fair value of liabilities assumed: Deposits 14,474 Total fair value of liabilities assumed $ 14,474

Accounting Pronouncements Recently Issued or Adopted [Abstract]
New Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which creates Topic 606 and supersedes Topic 605, Revenue Recognition. In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606), which postponed the effective date of 2014-09. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net, which amended the principal versus agent implementation guidance set for in ASU 2014-09. Among other things, ASU 2016-08 clarifies that an entity should evaluate whether it is the principal or the agent for each specified good or service promised in a contract with a customer. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. The ASU amends certain aspects of the guidance set forth in the FASB's new revenue standard related to identifying performance obligations and licensing implementation. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In general, the new ASU requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which provides clarifying guidance in certain narrow areas and adds some practical expedients, but does not change the core revenue recognition principle in Topic 606. This ASU is effective for interim and annual periods beginning after December 15, 2017; early adoption is not permitted. For financial reporting purposes, the ASU allows for either full retrospective adoption, meaning this ASU is applied to all of the periods presented, or modified retrospective adoption, meaning the ASU is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the ASU recognized at the date of initial application. As a financial institution, the Company's largest component of revenue, interest income, is excluded from the scope of this ASU. Accordingly, the adoption of ASU No. 2014-09 is not expected to have a material impact on the Company’s consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. The new guidance is intended to improve the recognition and measurement of financial instruments. This ASU requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. In addition, the ASU requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes and requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. This ASU also eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. The ASU also requires a reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument specific credit risk (also referred to as “own credit”) when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. ASU No. 2016-01 is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted for certain provisions. The Company is currently evaluating the impact of this ASU on the Company's consolidated financial statements. In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842). ASU No. 2016-02 requires lessees to recognize, on the balance sheet, the assets and liabilities arising from operating leases. A lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. A lessee should include payments to be made in an optional period only if the lessee is reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease. For a finance lease, interest payments should be recognized separately from amortization of the right-of-use asset in the statement of comprehensive income. For operating leases, the lease cost should be allocated over the lease term on a generally straight-line basis. The amendments in ASU 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments in the ASU is permitted. Although an estimate of the impact of the new leasing standard has not yet been determined, once adopted, we expect to report higher assets and liabilities as a result of including right-of-use assets and lease liabilities related to certain banking offices and certain equipment under noncancelable operating lease agreements, however, based on current leases the adoption is not expected to have a material impact on the Company’s consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU replaces the existing incurred loss impairment methodology that recognizes credit losses when a probable loss has been incurred with new methodology where loss estimates are based upon lifetime expected credit losses. The amendments in this ASU require a financial asset that is measured at amortized cost to be presented at the net amount expected to be collected. The income statement would then reflect the measurement of credit losses for newly recognized financial assets as well as changes to the expected credit losses that have taken place during the reporting period. The measurement of expected credit losses will be based on historical information, current conditions, and reasonable and supportable forecasts that impact the collectability of the reported amount. Available-for-sale securities will bifurcate the fair value mark and establish an allowance for credit losses through the income statement for the credit portion of that mark. The interest portion will continue to be recognized through accumulated other comprehensive income or loss. The change in allowance recognized as a result of adoption will occur through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019 with early adoption permitted after December 15, 2018. The Company has begun the process to implement this new standard by working with a vendor that specializes in this area. While the Company has not quantified the impact of this ASU, it does expect changing from the current incurred loss model to an expected loss model will result in an earlier recognition of losses. The Company also expects that once adopted the allowance for loan losses will increase, however, until its evaluation is complete the magnitude of the increase will be unknown. In August 2016, FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses the appropriate classification of eight specific cash flow issues on the cash flow statement. Debt prepayment costs should be classified as an outflow for financing activities. Settlement of zero-coupon debt instruments divides the interest portion as an outflow for operating activities and the principal portion as an outflow for financing activities. Contingent consideration payments made after a business combination should be classified as outflows for financing and operating activities. Proceeds from the settlement of bank-owned life insurance policies should be classified as inflows from investing activities. Other specific areas are identified in the ASU as to the appropriate classification of the cash inflows or outflows. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted and must be applied using a retrospective transition method to each period presented. The Company does not expect this ASU to have a material impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20). ASU 2017-08 is intended to amend the amortization period for certain purchased callable debt securities held at a premium. Under ASU 2017-08, the FASB is shortening the amortization period for the premium to the earliest call date. Under current GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the instrument. ASU 2017-08 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. The Company is reviewing its securities portfolio to assess the impact the adoption of this ASU will have on the Company’s consolidated financial statements but does not expect this ASU to have a material impact. In May 2017, the FASB issued ASU No. 2017-09, Compensation--Stock Compensation (Topic 718): Scope of Modification Accounting
