Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations - FS Bancorp, Inc. (the “Company”) was incorporated in September 2011 as the proposed holding company for 1st Security Bank of Washington (the “Bank”) in connection with the Bank's conversion from the mutual to stock form of ownership which was completed on July 9, 2012. The Bank is a community-based savings bank with seven branches and three loan production offices in suburban communities in the greater Puget Sound area, and one loan production office in the market area of the Tri-Cities, Washington. The Bank provides loan and deposit services to customers who are predominantly small and middle-market businesses and individuals. The Company and its subsidiary are subject to regulation by certain federal and state agencies and undergo periodic examination by these regulatory agencies. Pursuant to the Plan of Conversion (the “Plan”) adopted by the Bank's Board of Directors and as approved by its depositors and borrower members, the Company's Board of Directors adopted an employee stock ownership plan ( “ESOP”) which purchased 8% of the common stock in the open market or 259,210 shares. As provided for in the Plan, the Bank also established a liquidation account in the amount of retained earnings at December 31, 2011. The liquidation account will be maintained for the benefits of eligible savings account holders as of June 30, 2007 and supplemental eligible account holders as of March 31, 2012 who maintain deposit accounts at the Bank after the conversion. The conversion was accounted for as a change in corporate form with the historic basis of the Bank’s assets, liabilities, and equity unchanged as a result. Financial Statement Presentation - The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and with prevailing practices within the banking and securities industries. In preparing such financial statements, management is required to make certain estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the balance sheet and the reported amounts of revenues and expenses for the reporting period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan and lease losses, fair value of financial instruments, the valuation of servicing rights, and the deferred income taxes . Amounts presented in the consolidated financial statements and footnote tables are rounded and presented in thousands of dollars except per share amounts. In the narrative footnote discussion, amounts are rounded and presented in millions of dollars to one decimal point if the amounts are above $ 1.0 million . Amounts below $ 1.0 million are rounded and presented to the nearest thousands. Certain prior year amounts have been reclassified to conform to the 2015 presentation with no change to net income or stockholders' equity previously reported. Principles of Consolidation - The consolidated financial statements include the accounts of FS Bancorp, Inc. and its wholly owned subsidiary, 1st Security Bank of Washington. All material intercompany accounts have been eliminated in consolidation. Segment Reporting - The Company’s major line of business is community banking. Management has determined that the Company operates as a single operating segment based on U.S. GAAP. Subsequent Events - The Company has evaluated events and transactions subsequent to December 31, 2015, for potential recognition or disclosure. On September 1, 2015, the Bank entered into a Purchase and Assumption Agreement for the acquisition of four retail bank branches from Bank of America, National Association. On January 22, 2016, the Bank completed the purchase of the branches. The four branches are located in the communities of Port Angeles, Sequim, Port Townsend, and Hadlock, Washington. In connection with the purchase, the Bank acquired approximately $186.4 million in deposits and $417,000 in loans based on January 22, 2016, financial information and subject to a post-closing confirmation and adjustment review. For additional information regarding this subsequent event please see Note 18 Recent Developments. Cash and Cash Equivalents - Cash and cash equivalents include cash and due from banks, and interest-bearing balances due from other banks and the Federal Reserve Bank of San Francisco ("FRB") and have a maturity of 90 days or less at the time of purchase. At December 31, 2015 the Company had no cash and due from banks and interest-bearing deposits at other financial institutions in excess of Federal Deposit Insurance Corporation ("FDIC") insured limits and at December 31, 2014, the Company had cash and due from banks and interest-bearing deposits at other financial institutions in excess of FDIC insured limits. Because the Company places these deposits with major financial institutions and monitors the financial condition of these institutions, management believes the risk of loss to any deposits in excess of FDIC limits to be minimal. Securities Available-for-Sale - Securities available-for-sale consist of debt securities that the Company has the intent and ability to hold for an indefinite period, but not necessarily to maturity. Such securities may be sold to implement the Company’s asset/liability management strategies and in response to changes in interest rates and similar factors. Securities available-for-sale are reported at fair value. Unrealized holding gains and losses, net of the related deferred tax effect, are reported as a net amount in a separate component of equity entitled accumulated other comprehensive income. Unrealized losses that are deemed to be other than temporary are reflected in results of operations. Any declines in the values of these securities that are considered to be other-than-temporary-impairment (“OTTI”) and credit-related are recognized in earnings. Noncredit-related OTTI on securities not expected to be sold is recognized in other comprehensive income. The review for OTTI is conducted on an ongoing basis and takes into account the severity and duration of the impairment, recent events specific to the issuer or industry, fair value in relationship to cost, extent and nature of change in fair value, creditworthiness of the issuer including external credit ratings and recent downgrades, trends and volatility of earnings, current analysts’ evaluations, and other key measures. In addition, the Company does not intend to sell the securities and it is more likely than not that we will not be required to sell the securities before recovery of their amortized cost basis. In doing this, we take into account our balance sheet management strategy and consideration of current and future market conditions. Realized gains and losses on securities available-for-sale, determined using the specific identification method, are included in results of operations. Amortization of premium and accretion of discounts are recognized in interest income over the period to maturity. Federal Home Loan Bank Stock - The Bank, as a member of the FHLB, is required to maintain an investment in capital stock of the FHLB in an amount of $ 601,000 and 4.0% of advances from the FHLB. The Bank's investment in FHLB stock is carried at par value ( $100 per share), which reasonably approximates its fair value. As of December 31, 2015 and 2014, $ 4.6 million and $ 750,000 , respectively, of FHLB stock was pledged as collateral for FHLB advances. The Bank’s investment in FHLB stock is carried at par value ( $100 per share) because the shares can only be redeemed with the FHLB at par. The Bank is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages and FHLB advances. Stock redemptions are at the discretion of the FHLB upon five years ’ prior notice for FHLB Class B stock or six months notice for FHLB Class A stock to the FHLB. FHLB stock is carried at cost and is subject to recoverability testing annually. Loans Held for Sale - The Bank records all mortgage loans held-for-sale at fair value. Fair value is determined by outstanding commitments from investors or current investor yield requirements calculated on the aggregate loan basis. Origination fees and costs are recognized in earnings at the time of origination. Mortgage loans held-for-sale are sold with the mortgage service rights released by the Bank. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loans sold. All sales are made without recourse. Derivatives - Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free-standing derivatives. The fair value of the interest rate lock is recorded at the time the commitment to fund the mortgage loan is executed and is adjusted for the expected exercise of the commitments to fund the loans, the Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest on the loan is locked. Changes in the fair values of these derivatives are included in other noninterest income on the Consolidated Statements of Income and included in gain on sale of loans. Loans Receivable - Loans receivable, are stated at the amount of unpaid principal reduced by an allowance for loan losses and net deferred fees or costs. Interest on loans is calculated using the simple interest method based on the daily balance of the principal amount outstanding and is credited to income as earned. Loan fees, net of direct origination costs, are deferred and amortized over the life of the loan using the effective yield method. Interest on loans is accrued daily based on the principal amount outstanding. Generally, the accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due or when they are past due 90 days as to either principal or interest (based on contractual terms), unless they are well secured and in the process of collection. All interest accrued but not collected for loans that are placed on non-accrual status or charged off are reversed against interest income. Subsequent collections on a cash basis are applied proportionately to past due principal and interest, unless collectability of principal is in doubt, in which case all payments are applied to principal. Loans are returned to accrual status when the loan is deemed current, and the collectability of principal and interest is no longer doubtful, or, generally, when the loan is less than 90 days delinquent, and performing according to contractual terms after a period of six months performance. The Company charges fees for originating loans. These fees, net of certain loan origination costs, are deferred and amortized to income, on the level-yield basis, over the loan term. If the loan is repaid prior to maturity, the remaining unamortized net deferred loan origination fee is recognized in income at the time of repayment. Impaired Loans - A loan is considered impaired when it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the original or modified terms of the loan agreement. Impaired loans are measured on a loan by loan basis based on the estimated fair value of the collateral less estimated cost to sell if the loan is considered collateral dependent. Impaired loans not considered to be collateral dependent are measured based on the present value of expected future cash flows. The categories of non-accrual loans and impaired loans overlap, although they are not coextensive. The Company considers all circumstances regarding the loan and borrower on an individual basis when determining whether an impaired loan should be placed on non-accrual status, such as the financial strength of the borrower, the collateral value, reasons for delay, payment record, the amount of past due and the number of days past due. Loans that experience insignificant payment delays and payment shortfalls are generally not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of shortfall in relation to the principal and interest owed. Allowance for Loan Losses - The allowance for loan losses is maintained at a level considered adequate to provide for probable losses on existing loans based on evaluating known and inherent risks in the loan portfolio. The allowance is reduced by loans charged-off and increased by provisions charged to earnings and recoveries on loans previously charged-off. The allowance is based on management’s periodic, systematic evaluation of factors underlying the quality of the loan portfolio including changes in the size and composition of the loan portfolio, the estimated value of any underlying collateral, actual loan loss experience, current economic conditions, and detailed analysis of individual loans for which full collectability may not be assured. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. While management uses the best information available to make its estimates, future adjustments to the allowance may be necessary if there is a significant change in economic and other conditions. The appropriateness of the allowance for loan losses is estimated based on these factors and trends identified by management at the time the financial statements are prepared. When available information confirms that specific loans or portions thereof are uncollectible, these amounts are charged-off against the allowance for loan losses. The existence of some or all of the following criteria will generally confirm that a loss has been incurred: the loan is significantly delinquent and the borrower has not evidenced the ability or intent to bring the loan current; the Company has no recourse to the borrower, or if it does, the borrower has insufficient assets to pay the debt; the estimated fair value of the loan collateral is significantly below the current loan balance, and there is little or no near-term prospect for improvement. A provision of loan losses is charged against income and added to the allowance for loan losses based on regular assessment of the loan portfolio. The allowance for loan losses is allocated to certain loan categories based on the relative risk characteristics, asset classifications, and actual loss experience within the loan portfolio. Although management has allocated the allowance for loan losses to various loan portfolio segments, the allowance is general in nature and is available for the loan portfolio in its entirety. The ultimate recovery of all loans is susceptible to future market factors beyond the Company’s control. These factors may result in losses or recoveries differing significantly from those provided for in the financial statements. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations. Reserve for Unfunded Loan Commitments - The reserve for unfunded loan commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to these unfunded credit facilities. The determination of the adequacy of the reserve is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. The reserve for unfunded loan commitments is included in other liabilities on the balance sheet, with changes to the balance charged against noninterest expense. Premises and Equipment, Net - Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The estimated useful lives used to compute depreciation include building and building improvements from 25 to 40 years and furniture, fixtures, and equipment from 3 to 10 years. Leasehold and tenant improvements are amortized using the straight-line method over the lesser of useful life or the life of the related lease. Depreciation and amortization expense for these assets totaled $ 1.2 million and $ 1.1 million for the years ended December 31, 2015 and 2014, respectively. Gains or losses on dispositions are reflected in results of operations. Management reviews buildings, improvements and equipment for impairment on an annual basis or whenever events or changes in the circumstances indicate that the undiscounted cash flows for the property are less than its carrying value. If identified, an impairment loss is recognized through a charge to earnings based on the fair value of the property. Transfers of Financial Assets - Transfers of an entire financial asset, a group of entire financial assets, or participating interest in an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Servicing Rights - Servicing assets are recognized as separate assets when rights are acquired through purchase or through sale of financial assets. Generally, purchased servicing rights are capitalized at the cost to acquire the rights. For sales of mortgage, commercial and consumer loans, a portion of the cost of originating the loan is allocated to the servicing right based on relative fair value. Fair value is based on market prices for comparable mortgage, commercial, or consumer servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds, and default rates and losses. Servicing assets are evaluated quarterly for impairment based upon the fair value of the rights as compared to amortized cost. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type, and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranches. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income. Capitalized servicing rights are stated separately on the consolidated balance sheets and are amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Income Taxes - The Company files a consolidated federal income tax return. Deferred federal income taxes result from temporary differences between the tax basis of assets and liabilities, and their reported amounts in the financial statements. These will result in differences between income for tax purposes and income for financial reporting purposes in future years. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established to reduce the net recorded amount of deferred tax assets if it is determined to be more likely than not, that all or some portion of the potential deferred tax asset will not be realized. The Financial Accounting Standards Board (“FASB”) issued guidance related to accounting for uncertainty in income taxes. The guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It is the Company’s policy to record any penalties or interest arising from federal or state taxes as a component of income tax expense. Employee Stock Ownership Plan ( “ ESOP ” ) - Compensation expense recognized for the Company's ESOP equals the fair value of shares that have been allocated or committed to be released for allocation to participants. Any difference between the fair value of the shares at the time and the ESOP's original acquisition cost is charged or credited to stockholders' equity (additional paid-in capital). The cost of ESOP shares that have not yet been allocated or committed to be released is deducted from stockholders' equity. Earnings Per Share - Basic earnings per share (“EPS”) are computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. For purposes of computing basic and dilutive EPS, ESOP shares that have been committed to be released are outstanding and ESOP shares that have not been committed to be released shall not be considered outstanding. Comprehensive Income (Loss) - Comprehensive income (loss) is comprised of net income and other comprehensive income (loss). Other comprehensive income (loss) includes items recorded directly to equity, such as unrealized holding gains and losses on securities available-for-sale. Financial Instruments - In the ordinary course of business, the Company has entered into agreements for off-balance-sheet financial instruments consisting of commitments to extend credit and stand-by letters of credit. Such financial instruments are recorded in the financial statements when they are funded or related fees are incurred or received. Restricted Assets - Federal Reserve regulations require that the Bank maintain reserves in the form of cash on hand and deposit balances with the FRB, based on a percentage of deposits. The amounts of such balances for the years ended December 31, 2015 and 2014 were $ 3.0 million and $ 1.9 million , respectively, included in interest-bearing deposits at other financial institutions on the balance sheet. The Bank pledged two securities held at the FHLB with a carrying value of $1.2 million to secure Washington State public deposits of $1.7 million at December 31, 2015. Marketing and Advertising Costs - The Company records marketing and advertising costs as expenses as they are incurred. Total marketing and advertising expense was $ 709,000 and $ 520,000 for the years ended December 31, 2015 and 2014, respectively. Stock-Based Compensation - Compensation cost is recognized for stock options and restricted stock awards, based on the fair value of these awards at the grant date. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company's common stock at the grant date is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. Application of New Accounting Guidance As of January 1, 2015, the Company applied FASB Accounting Standards Update (“ASU”) No 2014-04, Receivables -Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure . ASU 2014-04 clarifies when a repossession or foreclosure has occurred. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The Company has applied this ASU by adding an additional disclosure to Note 3, Loans Receivable and Allowance for Loan Losses. RECENT ACCOUNTING PRONOUNCEMENTS In January 2015, the FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20) . The objective of this ASU is to simplify the income statement presentation requirements in Subtopic 225-20 by eliminating the concept of extraordinary items. Extraordinary items are events and transactions that are distinguished by their unusual nature and by the infrequency of their occurrence. Eliminating the extraordinary classification simplifies income statement presentation by altogether removing the concept of extraordinary items from consideration. This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015 with early adoption permitted. The Company does not expect this ASU to have a material impact on the Company's consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis , which is intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). The ASU focuses on simplifying the consolidation evaluation for reporting organizations that are required to evaluate whether they should consolidate certain legal entities by reducing the number of consolidation model from four to two, among other changes. The ASU will be effective for periods beginning after December 31, 2015, while early adoption is permitted. The Company does not expect this ASU to have a material impact on the Company's consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs . The amendments in this ASU require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected. The ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. ASU No. 2015-03 should be applied on a retrospective basis. The Company is currently evaluating the impacts of this ASU on the Company's consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement . The amendments in this ASU provide guidance to customers in cloud computing arrangements about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement does include a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The amendments are effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. This ASU is not expected to have a material effect on the Company's consolidated financial statements. In June 2015, FASB issued ASU No. 2015-10, Technical Corrections and Improvements . On November 10, 2010 FASB added a standing project that will facilitate the FASB Accounting Standards Codification ("Codification") updates for technical corrections, clarifications, and improvements. These amendments are referred to as Technical Corrections and Improvements. Maintenance updates include non-substantive corrections to the Codification, such as editorial corrections, various link-related changes, and changes to source fragment information. This update contains amendments that will affect a wide variety of Topics in the Codification. The amendments in this ASU will apply to all reporting entities within the scope of the affected accounting guidance and generally fall into one of four categories: amendments related to differences between original guidance and the Codification, guidance clarification and reference corrections, simplification, and minor improvements. In summary, the amendments in this ASU represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have a significant effect on current accounting practice. Transition guidance varies based on the amendments in this ASU. The amendments in this ASU that require transition guidance are effective for fiscal years and interim reporting periods after December 15, 2015. Early adoption is permitted including adoption in an interim period. All other amendments are effective upon the issuance of this ASU. ASU 2015-10 did not have a material impact on the Company's consolidated financial statements. In July 2015, the FASB issued ASU 2015-12, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965): (Part I) Fully Benefit-Responsive Investment Contracts, (Part II) Plan Investment Disclosures, (Part III) Measurement Date Practical Expedient (consensuses of the FASB Emerging Issues Task Force) . The amendments of this ASU (i) require fully benefit-responsive investment contracts to be measured, presented and disclosed only at contract value, not fair value; (ii) simplify the investment disclosure requirements; and (iii) provide a measurement date practical expedient for employee benefit plans. This ASU is effective for fiscal years beginning after December 15, 2015, although earlier adoption is permitted. This ASU is not expected to have a material effect on the Company's consolidated financial statements. In July 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers, deferring the effective date of the new revenue standard by one year . The standard also allows entities to choose to adopt the standard as of the original effective date. The FASB decided, based on its outreach to various stakeholders and the forthcoming amendments to the new revenue standard, that a deferral is necessary to provide adequate time to effectively implement the new revenue standard. In August 2015, the FASB issued ASU No. 2015-15, Interest-Imputation of Interest (Subtopic 835-30), Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements . The ASU provides guidance not previously included in ASU 2015-03 regarding debt issuance related to line-of-credit arrangements. The amendment allows an entity to present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs over the term of the line-of-credit a

There were eight investments with unrealized losses of less than one year and 13 investments with unrealized losses of more than one year at December 31, 2014. The unrealized losses associated with these investments are believed to be caused by changing market conditions that are considered to be temporary and the Company does not intend to sell these securities, and is not likely to be required to sell these securities. No other-than-temporary impairments were recorded for the years ended December 31, 2015 and 2014. The contractual maturities of securities available-for-sale at December 31, 2015 and 2014 are listed below. Expected maturities of mortgage-backed securities may differ from contractual maturities because borrowers may have the right to call or prepay the obligations; therefore, these securities are classified separately with no specific maturity date.

The three loan portfolio segments are: (a) Real Estate Loans, (b) Consumer Loans and (c) Commercial Business Loans. Each of these segments is disaggregated into classes based on the risk characteristics of the borrower and/or the collateral type securing the loan. The following is a summary of each of the Company’s loan portfolio segments and classes: Real Estate Loans Commercial Lending . Loans originated by the Company primarily secured by income producing properties, including retail centers, warehouses and office buildings located in our market areas. Construction and Development Lending . Loans originated by the Company for the construction of, and secured by, commercial real estate, one -to- four -family, and multi-family residences and tracts of land for development that are not pre-sold.

Multi-family Lending . Apartment term lending ( five or more units) to current banking customers and community reinvestment loans for low to moderate income individuals in the Company's footprint. Consumer Loans Indirect Home Improvement . Fixture secured loans are originated by the Company for home improvement and are secured by the personal property installed in, on, or at the borrower’s real property, and may be perfected with a UCC-2 financing statement filed in the county of the borrower’s residence. These indirect home improvement loans include replacement windows, siding, roofing, and other home fixture installations. Solar. Fixture secured loans are originated by the Company for home improvement and are secured by the personal property installed in, on, or at the borrower’s real property, and may be perfected with a UCC-2 financing statement filed in the county of the borrower’s residence.

tracks certain credit quality indicators including trends related to (i) the risk grading of loans, (ii) the level of classified loans, (iii) net charge-offs, (iv) non-performing loans and (v) the general economic conditions in the Company’s markets. The Company utilizes a risk grading matrix to assign a risk grade to its real estate and commercial business loans. Loans are graded on a scale of 1 to 10 , with loans in risk grades 1 to 6 considered “Pass” and loans in risk grades 7 to 10 are reported as classified loans in the Company's allowance for loan loss analysis. A description of the 10 risk grades is as follows: • Grades 1 and 2 - These grades include loans to very high quality borrowers with excellent or desirable business credit. • Grade 3 - This grade includes loans to borrowers of good business credit with moderate risk. • Grades 4 and 5 - These grades include “Pass” grade loans to borrowers of average credit quality and risk. • Grade 6 - This grade includes loans on management’s “Watch” list and is intended to be utilized on a temporary basis for “Pass” grade borrowers where frequent and thorough monitoring is required due to credit weaknesses and where significant risk-modifying action is anticipated in the near term. • Grade 7 - This grade is for “Other Assets Especially Mentioned (OAEM)” in accordance with regulatory guidelines and includes borrowers where performance is poor or significantly less than expected. • Grade 8 - This grade includes “Substandard” loans in accordance with regulatory guidelines which represent an unacceptable business credit where a loss is possible if loan weakness is not corrected. • Grade 9 - This grade includes “Doubtful” loans in accordance with regulatory guidelines where a loss is highly probable. • Grade 10 - This grade includes “Loss” loans in accordance with regulatory guidelines for which total loss is expected and when identified are charged off. Consumer, Home Equity and One-to-Four-Family Real Estate Loans Homogeneous loans are risk rated based upon the FDIC's Uniform Retail Credit Classification and Account Management Policy. Loans classified under this policy at the Company are consumer loans which include indirect home improvement, recreational, automobile, direct home improvement and other consumer, and one-to-four-family first and second liens. Under the Uniform Retail Credit Classification Policy, loans that are current or less than 90 days past due are graded “Pass” and risk graded " 4 " internally. Loans that are past due more than 90 days are classified “Substandard” risk graded " 8 " internally. Closed-end loans that are 120 days past due, and open-end loans that are 180 days past due are charged off based on the value of the collateral less cost to sell.

The loan terms which have been modified or restructured due to a borrower’s financial difficulty include but are not limited to: a reduction in the stated interest rate; an extension of the maturity at an interest rate below current market; a reduction in the face amount of the debt; a reduction in the accrued interest; or re-aging, extensions, deferrals and renewals. TDR loans are considered impaired loans and are individually evaluated for impairment. TDR loans can be classified as either accrual or non-accrual. TDR loans are classified as non-performing loans unless they have been performing in accordance with their modified terms for a period of at least six months in which case they are placed on accrual status. The Company had two TDR loans still on accrual and included in impaired loans at December 31, 2015, and four TDR loans at December 31, 2014. In addition, the Company had one TDR loan on non-accrual, and had no commitments to lend additional funds on these restructured loans at December 31, 2015, and no TDR loans on non-accrual at December 31, 2014. At December 31, 2015 and 2014, all of the Company’s TDR loans consist of one-to-four-family loans. A summary of TDR one-to-four-family loan balances at the dates indicated is as follows: December 31, 2015 2014 TDR loans still on accrual $ 209 $ 783 TDR loans on non-accrual 525 — Total TDR loan balances $ 734 $ 783 For the years ended December 31, 2015 and 2014 there were no reported TDR loans that were modified in the previous 12 months that subsequently defaulted in the reporting year. At December 31, 2015, there was a $ 525,000 mortgage loan collateralized by residential real estate property in the process of foreclosure. Related Party Loans Certain directors and executive officers or their related affiliates are customers of and have had banking transactions with the Company. At December 31, 2015, there was one new home equity line of credit ("HELOC") to a director with an outstanding balance of zero and an unfunded commitment of $ 150,000 and one existing personal line of credit with an outstanding balance of zero and an unfunded commitment of $ 50,000 . The existing personal line of credit had an outstanding balance of $ 13,000 and an unfunded commitment of $ 37,000 at December 31, 2014. These lines of credit were made in compliance with applicable laws on substantially the same terms (including interest rates and collateral) as those prevailing at the time for comparable transactions with other persons and do not involve more than the normal risk of collectability or present any other unfavorable features.

Fair Value, Off-balance Sheet Risk [Abstract]
Servicing Rights	SERVICING RIGHTS Loans serviced for others are not included on the Consolidated Balance Sheets. The unpaid principal balances of mortgage, commercial, and consumer loans serviced for others were $ 636.1 million and $ 345.9 million at December 31, 2015 and 2014, respectively and are carried at the lower of cost or market. At December 31, 2015 and December 31, 2014, mortgage, commercial and consumer servicing rights' assets ("servicing rights") are recorded on the Consolidated Balance Sheets at a book value of $5.8 million and $3.1 million, respectively. The fair market value of the servicing rights' assets was $ 6.8 million and $ 3.5 million at December 31, 2015 and December 31, 2014, respectively. The following summarizes servicing rights activity for the years ended December 31, 2015 and 2014: 2015 2014 Beginning balance $ 3,061 $ 2,093 Additions 3,699 1,514 Servicing rights amortized (949 ) (564 ) Recovery on servicing rights — 18 Ending balance $ 5,811 $ 3,061 Fair value adjustments to servicing rights were mainly due to market based assumptions associated with discounted cash flows, loan prepayment speeds, and changes in interest rates. A significant change in prepayments of the loans in the servicing portfolio could result in significant changes in the valuation adjustments, thus creating potential volatility in the carrying amount of servicing rights. Valuation assumptions used in determining the fair value of commercial and consumer servicing rights were excluded from the tables below due to immateriality, mortgage servicing rights ("MSR") are included at the dates indicated as follows: At December 31, Key assumptions: 2015 2014 Weighted average discount rate 8.5 % 8.5 % Conditional prepayment rate ("CPR") 12.2 % 13.2 % Weighted average life in years 6.4 6.1 Key economic assumptions and the sensitivity of the current fair value for single family mortgage servicing rights to immediate adverse changes in those assumptions at December 31, 2015 and December 31, 2014 were as follows: December 31, 2015 December 31, 2014 Aggregate portfolio principal balance $ 631,812 $ 340,243 Weighted average rate of note 4.0 % 4.1 % At December 31, 2015 Base 0.5% Adverse Change 1.0% Adverse Change Conditional Prepayment Rate 12.2 % 17.8 % 25.3 % Fair value MSR $ 6,813 $ 5,660 $ 4,557 Percentage of MSR 1.1 % 0.9 % 0.7 % Discount rate 8.5 % 9.0 % 9.5 % Fair value MSR $ 6,813 $ 6,678 $ 6,548 Percentage of MSR 1.1 % 1.1 % 1.0 % At December 31, 2014 Base 0.5% Adverse Change 1.0% Adverse Change Conditional prepayment rate 13.2 % 19.4 % 28.0 % Fair value MSR $ 3,526 $ 2,887 $ 2,265 Percentage of MSR 1.0 % 0.8 % 0.7 % Discount rate 8.5 % 9.0 % 9.5 % Fair value MSR $ 3,526 $ 3,457 $ 3,391 Percentage of MSR 1.0 % 1.0 % 1.0 % The above tables show the sensitivity to market rate changes for the par rate coupon for a conventional one-to-four-family FNMA/FHLMC/GNMA serviced home loan. The above tables reference a 50 basis point and 100 basis point decrease in note rate. These sensitivities are hypothetical and should be used with caution as the tables above demonstrate the Company's methodology for estimating the fair value of MSR is highly sensitive to changes in key assumptions. For example, actual prepayment experience may differ and any difference may have a material effect on MSR fair value. Changes in fair value resulting from changes in assumptions generally cannot be extrapolated because the relationship of the change in the assumption to the change in fair value may not be linear. Also, in these tables, the effects of a variation in a particular assumption on the fair value of the MSR is calculated without changing any other assumption; in reality, changes in one factor may be associated with changes in another (for example, decreases in market interest rates may provide an incentive to refinance; however, this may also indicate a slowing economy and an increase in the unemployment rate, which reduces the number of borrowers who qualify for refinancing), which may magnify or counteract the sensitivities. Thus, any measurement of MSR fair value is limited by the conditions existing and assumptions made as a particular point in time. Those assumptions may not be appropriate if they are applied to a different point in time. The Company recorded $ 1.3 million and $ 722,000 of contractually specified servicing fees, late fees, and other ancillary fees resulting from serving of mortgage, commercial and consumer loans for the years ended December 31, 2015 and 2014, respectively. The income, net of amortization, is reported in noninterest income.

Debt Disclosure [Abstract]
Borrowings	DEBT Borrowings The Bank is a member of the FHLB, which entitles it to certain benefits including a variety of borrowing options consisting of a secured credit line that allows both fixed and variable rate advances. The FHLB borrowings at December 31, 2015 and 2014, consisted of a warehouse securities credit line (“securities line”), which allows advances with interest rates fixed at the time of borrowing and a warehouse Fed Funds advance, which allows daily advances at variable interest rates. Credit capacity is primarily determined by the value of assets collateralized at the FHLB, funds on deposit at the FHLB, and stock owned by the Bank. Credit is limited to 35% of the Company’s total assets. The Bank entered into an Advanced, Pledges and Security Agreement with the FHLB for which specific loans are pledged to secure these credit lines. At December 31, 2015, loans of approximately $206.2 million were pledged to the FHLB with a borrowing capacity of $153.8 million . In addition, all FHLB stock owned by the Company is collateral for credit lines. The Bank maintains a short-term borrowing line with the FRB with total credit based on eligible collateral. The Bank can borrow under the Term Auction or Term Facility at rates published by the San Francisco FRB. As of December 31, 2015 and 2014, the Bank had a Term Auction or Term Facility borrowing capacity of $79.5 million and $ 69.6 million , respectively, of which none was outstanding at either date. The Bank also had $40.0 million unsecured Fed Funds lines of credit with other large financial institutions of which none was outstanding at December 31, 2015. Advances on these lines at December 31, 2015 and 2014 were as follows: 2015 2014 Federal Home Loan Bank - (interest ranging from 0.34% to 1.73% and 0.27% to 4.57% at December 31, 2015 and 2014, respectively) $ 98,769 $ 17,034 Total $ 98,769 $ 17,034 Subordinated Note On October 15, 2015 (the “Closing Date”), FS Bancorp, Inc. issued an unsecured subordinated term note in the aggregate principal amount of $10.0 million due October 1, 2025 (the “Subordinated Note”) pursuant to a Subordinated Loan Agreement with Community Funding CLO, Ltdy. The Subordinated Note bears interest at an annual interest rate of 6.50% , payable by the Company quarterly in arrears on January 1, April 1, July 1 and October 1 of each year, commencing on the first such date following the Closing Date and on the maturity date.

Employee Benefits	EMPLOYEE BENEFITS Employee Stock Ownership Plan On January 1, 2012, the Company established an ESOP for eligible employees of the Company and the Bank. Employees of the Company and the Bank who have been credited with at least 1000 hours of service during a 12 -month period are eligible to participate in the ESOP. The ESOP borrowed $ 2.6 million from FS Bancorp, Inc. and used those funds to acquire 259,210 shares of FS Bancorp, Inc. common stock in the open market at an average price of $ 10.17 per share during the second half of 2012. It is anticipated that the Bank will make contributions to the ESOP in amounts necessary to amortize the ESOP loan payable to FS Bancorp, Inc. over a period of 10 years , bearing interest at 2.30% . Intercompany expenses associated with the ESOP are eliminated in consolidation. Shares purchased by the ESOP with the loan proceeds are held in a suspense account and allocated to ESOP participants on a pro rata basis as principal and interest payments are made by the ESOP to FS Bancorp, Inc. The loan is secured by shares purchased with the loan proceeds and will be repaid by the ESOP with funds from the Bank's discretionary contributions to the ESOP and earnings on the ESOP assets. Payments of principal and interest are due annually on December 31, the Company's fiscal year end. On December 31, 2015, the ESOP made the fourth annual installment payment of principal in the amount of $ 251,000 , plus accrued interest of $ 44,000 pursuant to the ESOP loan agreement. As shares are committed to be released from collateral, the Company reports compensation expense equal to the average daily market prices of the shares at December 31, 2015 for the prior 90 days. These shares become outstanding for EPS computations. The compensation expense is accrued monthly throughout the year. Dividends on allocated ESOP shares are recorded as a reduction of retained earnings; dividends on unallocated ESOP shares are recorded as a reduction of debt and accrued interest. Compensation expense related to the ESOP for the years ended December 31, 2015 and 2014, was $ 652,000 and $ 446,000 , respectively. Shares held by the ESOP at December 31, 2015 and December 31, 2014, were as follows: December 31, 2015 2014 Allocated shares 102,359 77,141 Committed to be released shares — — Unallocated shares 155,526 181,447 Total ESOP shares 257,885 258,588 Fair value of unallocated shares (in thousands) $ 3,913 $ 3,125 401(k) Plan The Company has a salary deferral 401(k) Plan covering substantially all of its employees. Employees are eligible to participate in the 401(k) plan at the date of hire if they are 18 years of age. Eligible employees may contribute through payroll deductions and are 100% vested at all times in their deferral contributions account. The Company matches 100% for contributions between 1% and 3% , and 50% for contributions between 4% and 5% .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Commitments - The Company is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized on the balance sheet. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. A summary of the Company’s commitments at December 31, 2015 and 2014, is as follows: COMMITMENTS TO EXTEND CREDIT 2015 2014 REAL ESTATE LOANS Commercial $ 1,988 $ — Construction and development 44,109 42,290 One-to-four-family (includes held for sale) 76,013 45,331 Home equity 18,089 13,735 Multi-family 429 474 Total real estate loans 140,628 101,830 CONSUMER LOANS 5,754 5,832 COMMERCIAL BUSINESS LOANS 67,138 54,664 Total commitments to extend credit $ 213,520 $ 162,326 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the amount of the total commitments do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate, and income-producing commercial properties. Unfunded commitments under commercial lines-of-credit, revolving credit lines and overdraft protection agreements are commitments for possible future extensions of credit to existing customers. These lines-of-credit are uncollateralized and usually do not contain a specified maturity date and ultimately may not be drawn upon to the total extent to which the Company is committed. The Company has established a reserve for estimated losses from unfunded commitments of $ 147,000 and $ 124,000 at December 31, 2015 and 2014, respectively, which is included in other liabilities in the Consolidated Balance Sheets. One-to-four-family commitments included in the table above are accounted for as fair value derivatives and do not carry an associated loss reserve. The Company has entered into a severance agreement with its Chief Executive Officer. The severance agreement, subject to certain requirements, generally includes a lump sum payment to the Chief Executive Officer equal to 24 months of base compensation in the event their employment is involuntarily terminated, other than for cause or the executive terminates his employment with good reason, as defined in the severance agreement. The Company has entered into change of control agreements with its Chief Financial Officer and the Chief Operating Officer. The change of control agreements, subject to certain requirements, generally remain in effect until canceled by either party upon at least 24 months prior written notice. Under the change of control agreements, the executive generally will be entitled to a change of control payment from the Company if the executive is involuntarily terminated within six months preceding or 12 months after a change in control (as defined in the change of control agreements). In such an event, the executives would each be entitled to receive a cash payment in an amount equal to 12 months of their then current salary, subject to certain requirements in the change of control agreements. Because of the nature of our activities, the Company is subject to various pending and threatened legal actions, which arise in the ordinary course of business. From time to time, subordination liens may create litigation which requires us to defend our lien rights. In the opinion of management, liabilities arising from these claims, if any, will not have a material effect on our financial position. The Company has no pending material legal actions as of December 31, 2015. Contingent liabilities for loans held for sale - In the ordinary course of business, the Company sells loans without recourse that may have to subsequently be repurchased due to defects that occurred during the origination of the loan. The defects are categorized as documentation errors, underwriting errors, early payment defaults, breach of representation or warranty servicing errors, and fraud. When a loan sold to an investor without recourse fails to perform according to its contractual terms, the investor will typically review the loan file to determine whether defects in the origination process occurred. If a defect is identified, the Company may be required to either repurchase the loan or indemnify the investor for losses sustained. If there are no such defects, the Company has no commitment to repurchase the loan. The Company has recorded reserves of $561,000 and $340,000 to cover loss exposure related to these guarantees for one-to-four-family loans sold into the secondary market at December 31, 2015 and 2014, respectively, which is included in other liabilities in the Consolidated Balance Sheets.

Rights to collateral vary and are legally documented to the extent practicable. Local economic conditions may affect borrowers’ ability to meet the stated repayment terms.

Regulatory Capital

Regulatory Capital Requirements [Abstract]
Regulatory Capital	REGULATORY CAPITAL As a state-chartered, federally insured savings bank, 1st Security Bank of Washington is subject to the capital requirements established by the FDIC. Under the FDIC’s 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 Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Effective January 1, 2015 (with some changes transitioned into full effectiveness over two to four years), the Bank became subject to new capital adequacy requirements. The capital adequacy requirements are quantitative measures established by regulation that require the Bank to maintain minimum amounts and ratios of capital. The Bank is now subject to new capital requirements adopted by the FDIC, which create a new required ratio for common equity Tier 1 ("CET1") capital, increases the leverage and Tier 1 capital ratios, changes the risk-weightings of certain assets for purposes of the risk-based capital ratios, creates an additional capital conservation buffer over the required capital ratios and changes what qualifies as capital for purpose of meeting these various capital requirements. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by bank regulators that, if undertaken, could have a direct material effect on the Company's consolidated financial statements. The Bank is required to maintain additional levels of Tier 1 common equity over the minimum risk-based capital levels before it may pay dividends, repurchase shares or pay discretionary bonuses. The new minimum requirements are a ratio of CET1 capital to total risk-weighted assets (the "CET1 risk-based ratio") of 4.5%, a Tier 1 capital ratio of 6.0%, a total capital ratio of 8.0%, and a leverage ratio of 4.0%. In addition to the minimum CET1, Tier 1 and total capital ratios, the Bank will have to maintain a capital conservation buffer consisting of additional CET1 capital equal to 2.5% of risk-weighted assets above the required minimum levels in order to avoid limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses based on percentages of eligible retained income that could be utilized for such actions. This new capital conservation buffer requirement is to be phased in beginning in January 2016 at 0.625% of risk-weighted assets and increasing each year until fully implemented in January 2019. In addition to the capital requirements, there are a number of changes in what constitutes regulatory capital, subject to transition periods. These changes include the phasing-out of certain instruments as qualifying capital. The Bank does not have any of these instruments. Mortgage servicing rights and deferred tax assets over designated percentages of CET1 will be deducted from capital, subject to a four-year transition period. CET1 will consist of Tier 1 capital less all capital components that are not considered common equity. In addition, Tier 1 capital will include accumulated other comprehensive income (loss), which includes all unrealized gains and losses on available for sale debt and equity securities, subject to a four-year transition period. Because of the Bank's asset size, it was not considered an advanced approaches banking organization and elected in the first quarter of calendar year 2015 to take the one-time option of deciding to permanently opt-out of the inclusion of unrealized gains and losses on available for sale debt and equity securities in our capital calculations. The new requirements also include changes in the risk-weighting of assets to better reflect credit risk and other risk exposure. These include a 150% risk weight (up from 100% ) for certain high volatility commercial real estate acquisition, development and construction loans and for non-residential mortgage loans that are 90 days or more past due or otherwise on non-accrual status; a 20% (up from 0% ) credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable; and a 250% risk weight (up from 100% ) for mortgage servicing rights and deferred tax assets that are not deducted from capital. . Under the new standards, in order to be considered well capitalized, the Bank must have a CET1 risk-based capital ratio of 6.5% (new), a Tier 1 risk-based capital ratio of 8.0% (increased from 6.0%), a total risk-based capital ratio of 10.0% (unchanged) and a Tier 1 leverage capital ratio of 5.0% (unchanged). At December 31, 2015 the Bank exceeded all regulatory capital requirements. The Bank was categorized as "well capitalized" at December 31, 2015 under the regulations of the FDIC. The following tables compare the Bank’s actual capital amounts at December 31, 2015 and 2014 to their minimum regulatory capital requirements and "Well Capitalized" regulatory capital at those dates (dollars in thousands): To be Well Capitalized Under Prompt Corrective Action Provisions For Capital Adequacy Purposes Actual Bank Only Amount Ratio Amount Ratio Amount Ratio At December 31, 2015 Total risk-based capital (to risk-weighted assets) $ 85,570 15.51 % $ 44,132 8.00 % $ 55,164 10.00 % Tier 1 risk-based capital (to risk-weighted assets) $ 78,662 14.26 % $ 33,099 6.00 % $ 44,132 8.00 % Tier 1 leverage capital (to average assets) $ 78,662 12.14 % $ 25,924 4.00 % $ 32,406 5.00 % Common equity tier 1 ("CET1") capital $ 78,662 14.26 % $ 24,824 4.50 % $ 35,857 6.50 % At December 31, 2014 Total risk-based capital (to risk-weighted assets) $ 60,978 14.68 % $ 33,223 8.00 % $ 41,529 10.00 % Tier 1 risk-based capital (to risk-weighted assets) $ 55,770 13.43 % $ 16,611 4.00 % $ 24,917 6.00 % Tier 1 leverage capital (to average assets) $ 55,770 11.17 % $ 19,965 4.00 % $ 24,956 5.00 % CET1 capital (1) — — % — — % — — % (1) The CET1 ratio is a new regulatory capital ratio which became effective in the quarter ended March 31, 2015. Bank holding companies are subject to capital adequacy requirements of the Federal Reserve under the Bank Holding Company Act of 1956, as amended, and the regulations of the Federal Reserve. For a bank holding company with less than $1.0 billion in assets, the capital guidelines apply on a bank only basis and the Federal Reserve expects the holding company's subsidiary banks to be well capitalized under the prompt corrective action regulations. If FS Bancorp was subject to regulatory guidelines for bank holding companies with $1.0 billion or more in assets, at December 31, 2015, FS Bancorp would have exceeded all regulatory capital requirements. The regulatory capital ratios calculated for FS Bancorp as of December 31, 2015 were 11.6% for Tier 1 leverage-based capital, 13.6% for Tier 1 risk-based capital, 14.9% for total risk-based capital, and 13.6% for CET1 capital.

Fair Value of Financial Instrum

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS The Company assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations. Consequently, the fair value of the Company's consolidated financial instruments will change when interest rate levels change and that change may either be favorable or unfavorable to the Company. Management attempts to match maturities of assets and liabilities to the extent believed necessary to minimize interest rate risk. However, borrowers with fixed interest rate obligations are less likely to prepay in a rising interest rate environment and more likely to prepay in a falling interest rate environment. Conversely, depositors who are receiving fixed interest rates are more likely to withdraw funds before maturity in a rising interest rate environment and less likely to do so in a falling interest rate environment. Management monitors interest rates and maturities of assets and liabilities, and attempts to minimize interest rate risk by adjusting terms of new loans, and deposits, and by investing in securities with terms that mitigate the Company's overall interest rate risk. Accounting guidance regarding fair value measurements defines fair value and establishes a framework for measuring fair value in accordance with U.S. GAAP. Fair value is the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. The following definitions describe the levels of inputs that may be used to measure fair value: Level 1 - Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 - Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3 - Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Determination of Fair Market Values: Securities - Securities available-for-sale are recorded at fair value on a recurring basis. The fair value of investments and mortgage-backed securities are provided by a third-party pricing service. These valuations are based on market data using pricing models that vary by asset class and incorporate available current trade, bid and other market information, and for structured securities, cash flow and loan performance data. The pricing processes utilize benchmark curves, benchmarking of similar securities, sector groupings, and matrix pricing. Option adjusted spread models are also used to assess the impact of changes in interest rates and to develop prepayment scenarios. Transfers between the fair value hierarchy are determined through the third-party service provider which, from time to time will transfer between levels based on market conditions per the related security. All models and processes used take into account market convention (Level 2). Mortgage Loans Held for Sale - The fair value of loans held for sale reflects the value of commitments with investors and/or the relative price as delivered into a TBA mortgage-backed security (Level 2). Derivative Instruments - The fair value of the interest rate lock commitments and forward sales commitments are estimated using quoted or published market prices for similar instruments, adjusted for factors such as pull-through rate assumptions based on historical information, where appropriate. To be announced ("TBA") mortgage-backed securities are recorded at fair value based on similar contracts in active markets (Level 2) while locks and forwards with customers and investors are recorded at fair value using similar contracts in the market and changes in the market interest rates (Level 2 and 3). Impaired Loans - Fair value adjustments to impaired collateral dependent loans are recorded to reflect partial write-downs based on the current appraised value of the collateral or internally developed models, which contain management’s assumptions (Level 3). The following tables present securities available-for-sale measured at fair value on a recurring basis: Securities Available-for-Sale At December 31, 2015 Level 1 Level 2 Level 3 Total U.S. agency securities $ — $ 6,035 $ — $ 6,035 Municipal bonds — 18,891 — 18,891 Corporate securities — 3,433 — 3,433 U.S. Small Business Administration securities — 4,023 — 4,023 Mortgage-backed securities — 22,835 — 22,835 Total $ — $ 55,217 $ — $ 55,217 Securities Available-for-Sale At December 31, 2014 Level 1 Level 2 Level 3 Total U.S. agency securities $ — $ 5,845 $ — $ 5,845 Municipal bonds — 16,161 — 16,161 Corporate securities — 4,437 — 4,437 U.S. Small Business Administration securities — 2,057 — 2,057 Mortgage-backed securities — 20,244 — 20,244 Total $ — $ 48,744 $ — $ 48,744 The following table presents mortgage loans held for sale measured at fair value on a recurring basis at December 31, 2015 and December 31, 2014: Mortgage Loans Held for Sale Level 1 Level 2 Level 3 Total December 31, 2015 $ — $ 44,925 $ — $ 44,925 December 31, 2014 $ — $ 25,983 $ — $ 25,983 The following tables present the fair value of interest rate lock commitments with customers, individual forward sale commitments with investors and paired off commitments with investors measured at their fair value on a recurring basis at December 31, 2015 and December 31, 2014.

Conversely, a decrease in the pull-through rate will result in a negative fair value adjustment (and a decrease in the fair value measurement). The following table provides a reconciliation of assets and liabilities measured at fair value using significant unobservable inputs (Level 3) on a recurring basis during the years ended December 31, 2015 and 2014. 2015 Beginning Balance Purchases and issuances Sales and settlements Ending Balance Net change in fair value for gains/(losses) relating to items held at end of year Interest rate lock commitments with customers $ 396 $ 11,041 $ (10,739 ) $ 698 $ 302 Individual forward sale commitments with investors 12 245 (183 ) 74 62 2014 Interest rate lock commitments with customers $ 166 $ 6,219 $ (5,989 ) $ 396 $ 230 Individual forward sale commitments with investors 45 (242 ) 209 12 (33 ) Gains (losses) on interest rate lock commitments carried at fair value are recorded in other noninterest income. Gains (losses) on individual forward sale commitments with investors carried at fair value are recorded within other noninterest income. Fair Values of Financial Instruments - Because broadly traded markets do not exist for most of the Company’s financial instruments, the fair value calculations attempt to incorporate the effect of current market conditions at a specific time. These determinations are subjective in nature, involve uncertainties and matters of significant judgment and do not include tax ramifications; therefore, the results cannot be determined with precision, substantiated by comparison to independent markets and may not be realized in an actual sale or immediate settlement of the instruments. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. For all of these reasons, the aggregation of the fair value calculations presented herein do not represent, and should not be construed to represent, the underlying value of the Company. The following methods and assumptions were used by the Company in estimating the fair values of financial instruments disclosed in these financial statements: Cash, and Cash Equivalents and Certificates of Deposit at Other Financial Institutions - The carrying amounts of cash and short-term instruments approximate their fair value (Level 1). Federal Home Loan Bank Stock - The par value of FHLB stock approximates its fair value (Level 2). Accrued Interest - The carrying amounts of accrued interest approximate its fair value (Level 2). Loans Receivable, Net - For variable rate loans that re-price frequently and have no significant change in credit risk, fair values are based on carrying values. Fair values for fixed rate loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers or similar credit quality (Level 3). Servicing Rights - The fair value of mortgage, commercial and consumer servicing rights are estimated using net present value of expected cash flows using a third party model that incorporates assumptions used in the industry to value such rights, adjusted for factors such as weighted average prepayments speeds based on historical information, where appropriate (Level 3). Deposits - The fair value of deposits with no stated maturity date is included at the amount payable on demand. Fair values for fixed rate certificates of deposit are estimated using a discounted cash flow calculation on interest rates currently offered on similar certificates (Level 2). Borrowings - The carrying amounts of advances maturing within 90 days approximate their fair values. The fair values of long-term advances are estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements (Level 2). Subordinated Note - The fair value of the Subordinated Note is based upon the average yield of debt issuances in the fourth quarter of 2015 for similarly sized issuances. The average rate of 6.8% was compared to FS Bancorp, Inc.'s rate of 6.5% to derive a fair value estimate (Level 2). Off-Balance Sheet Instruments - The fair value of commitments to extend credit are estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreement and the present creditworthiness of the customers. The majority of the Company’s off-balance-sheet instruments consist of non-fee producing, variable-rate commitments, the Company has determined they do not have a distinguishable fair value. The fair value of loan lock commitments with customers and investors reflect an estimate of value based upon the interest rate lock date, the expected pull through percentage for the commitment, and the interest rate at year end (Level 2 and 3). The estimated fair values of the Company’s financial instruments at December 31, 2015 and 2014, were as follows: 2015 2014 Financial Assets Carrying Amount Fair Value Carrying Amount Fair Value Level 1 inputs: Cash and cash equivalents $ 24,445 $ 24,445 $ 15,555 $ 15,555 Certificates of deposit at other financial institutions 12,421 12,421 4,543 4,543 Level 2 inputs: Securities available-for-sale, at fair value 55,217 55,217 48,744 48,744 Loans held for sale, at fair value 44,925 44,925 25,983 25,983 FHLB stock, at cost 4,551 4,551 1,650 1,650 Accrued interest receivable 2,107 2,107 1,558 1,558 Individual forward sale commitments with investors 3 3 — — Paired off commitments with investors 30 30 — — Level 3 inputs: Loans receivable, net 502,535 566,209 387,174 433,885 Servicing rights, held at lower of cost or fair value 5,811 6,848 3,061 3,549 Fair value interest rate locks with customers 698 698 396 396 Individual forward sale commitments with investors 74 74 12 12 Financial Liabilities Level 2 inputs: Deposits 485,178 494,871 420,444 424,672 Borrowings 98,769 98,739 17,034 17,031 Subordinated note 10,000 9,550 — — Accrued interest payable 22 22 24 24 Individual forward sale commitments with investors — — 194 194 Paired off commitments with investors — — 207 207

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share are computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the year. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. The following table presents a reconciliation of the components used to compute basic and diluted earnings per share for the years ended December 31, 2015 and 2014. At or For the Years Ended December 31, Numerator: 2015 2014 Net Income (in thousands) $ 8,876 $ 4,540 Denominator: Basic weighted average common shares outstanding 2,978,165 2,979,099 Dilutive shares 54,352 6,965 Diluted weighted average common shares outstanding 3,032,517 2,986,064 Basic earnings per share $ 2.98 $ 1.52 Diluted earnings per share $ 2.93 $ 1.52 Potentially dilutive weighted average share options that were not included in the computation of diluted EPS because to do so would be anti-dilutive — 25,589 The Company purchased 259,210 shares in the open market during the year ended December 31, 2012, for the ESOP. For earnings per share calculations, the ESOP shares committed to be released are included as outstanding shares for both basic and diluted earnings per share. There were 155,526 shares in the ESOP that were not committed to be released at December 31, 2015.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	DERIVATIVES The Company regularly enters into commitments to originate and sell loans held for sale. The Company has established a hedging strategy to protect itself against the risk of loss associated with interest rate movements on loan commitments. The Company enters into contracts to sell forward To-Be-Announced (“TBA”) mortgage-backed securities. These commitments and contracts are considered derivatives but have not been designated as hedging instruments. Rather, they are accounted for as free-standing derivatives, or economic hedges, with changes in the fair value of the derivatives reported in noninterest income. The Company recognizes all derivative instruments as either other assets or other liabilities on the Consolidated Balance Sheets and measures those instruments at fair value. The following tables summarize the Company's derivative instruments as of the dates indicated: December 31, 2015 Fair Value Notional Asset Liability Fallout adjusted interest rate lock commitments with customers $ 34,154 $ 698 $ — Mandatory and best effort forward commitments with investors 24,135 74 — Forward TBA mortgage-backed securities 49,000 3 — TBA mortgage-backed securities forward sales paired off with investors 28,500 30 — December 31, 2014 Fair Value Notional Asset Liability Fallout adjusted interest rate lock commitments with customers $ 16,516 $ 396 $ — Mandatory and best effort forward commitments with investors 10,763 12 — Forward TBA mortgage-backed securities 30,000 — 194 TBA mortgage-backed securities forward sales paired off with investors 29,000 — 207 Changes in the fair value of the derivatives recognized in other noninterest income on the Consolidated Statements of Income and included in gain on sale of loans was $ 1.9 million and $ 777,000 for the years ended December 31, 2015 and 2014, respectively.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION Stock Options and Restricted Stock In September 2013, the shareholders of FS Bancorp, Inc. approved the FS Bancorp, Inc. 2013 Equity Incentive Plan (“Plan”). The Plan provides for the grant of stock options and restricted stock awards. Total share-based compensation expense for the Plan was $ 746,000 for the year ended December 31, 2015, and $483,000 for the year ended December 31, 2014. The related income tax benefit was $ 265,000 for the year ended December 31, 2015, and $164,000 for 2014. Stock Options The Plan authorizes the grant of stock options totaling 324,013 shares to Company directors and employees. Option awards are granted with an exercise price equal to the market price of FS Bancorp's common stock at the grant date. May 8, 2014, of $16.89 per share. These option awards were granted as non-qualified stock options, having a vesting period of five years, with 20% vesting on the anniversary date of each grant date, and a contractual life of 10 years. Any unexercised stock options will expire 10 years after the grant date or sooner in the event of the award recipient’s termination of service with the Company or the Bank. The fair value of each option award is estimated on the grant date using a Black-Scholes Option pricing model that uses the following assumptions. The dividend yield is based on the current quarterly dividend in effect at the time of the grant. Historical employment data is used to estimate the forfeiture rate. The Company became a publicly held company in July 2012, therefore historical data was not available to calculate the volatility for FS Bancorp stock. Given this limitation, management utilized a proxy to determine the expected volatility of FS Bancorp’s stock. The proxy chosen was the NASDAQ Bank Index, or NASDAQ Bank (NASDAQ symbol: BANK). This index provides the volatility of the banking sector for NASDAQ traded banks. The majority of smaller banks are traded on the NASDAQ given the costs and daily interaction required with trading on the New York Stock Exchange. The Company utilized the comparable Treasury rate for the discount rate associated with the stock options granted. The Company elected to use Staff Accounting Bulletin 107, simplified expected term calculation for the “Share-Based Payments” method as permitted by the U.S. Securities and Exchange Commission to calculate the expected term. This method uses the vesting term of an option along with the contractual term, setting the expected life at 6.5 years. The fair value of options granted was determined using the following weighted-average assumptions as of the grant date for the period indicated. There were no options granted in 2015. Year Ended December 31, 2014 Dividend yield 1.42 % Expected volatility 22.11 % Risk-free interest rate 1.92 % Expected term in years 6.5 Weighted-average grant date fair value per option granted $ 3.62 A summary of the Company's stock option plan awards during the year ended December 31, 2015 is as follows (shown as actual): Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term In Years Aggregate Intrinsic Value Outstanding at January 1, 2015 322,000 $ 16.89 9.36 $ 437,920 Granted — — — Exercised 11,100 16.89 57,724 Forfeited or expired 4,000 16.89 — Outstanding at December 31, 2015 306,900 $ 16.89 8.36 $ 2,794,570 Expected to vest, assuming a 0.31% annual forfeiture rate 305,444 $ 16.89 8.36 $ 2,781,315 Exercisable at December 31, 2015 53,300 $ 16.89 8.36 $ 485,339 For the year ended December 31, 2015, there was $769,000 of total unrecognized compensation cost related to nonvested stock options granted under the Plan. The cost is expected to be recognized over the remaining weighted-average vesting period of 3.4 years. Restricted Stock Awards The Plan authorizes the grant of restricted stock awards totaling 129,605 shares to Company directors and employees, and all but 4,500 shares were granted on May 8, 2014. Compensation expense is recognized over the vesting period of the awards based on the fair value of the stock at the grant date of $16.89 per share. The restricted stock awards’ fair value is equal to the value on the grant date. Shares awarded as restricted stock vest ratably over a three -year period for directors and a five -year period for employees, beginning at the grant date. Any unexercised restricted stock awards will expire after vesting or sooner in the event of the award recipient’s termination of service with the Company or the Bank. A summary of the Company's nonvested awards during the year ended December 31, 2015 is as follows (shown as actual): Nonvested Shares Shares Weighted-Average Grant-Date Fair Value Per Share Weighted-Average Grant-Date Fair Value Nonvested at January 1, 2015 125,105 $ 16.89 $ 2,113,023 Granted — — — Vested 30,421 16.89 513,811 Forfeited or expired — — — Nonvested at December 31, 2015 94,684 $ 16.89 $ 1,599,212 For the year ended December 31, 2015, there was $1.3 million of total unrecognized compensation costs related to nonvested shares granted as restricted stock awards. The cost is expected to be recognized over the remaining weighted-average vesting period of 2.9 years.

Subsequent Events [Abstract]
Recent Developments	Acquisition of Four Bank of America Branches On January 22, 2016, 1st Security Bank purchased four branches from Bank of America. The acquisition includes the branch banking operations of a total of four retail bank branches located in the communities of Port Angeles, Sequim, Port Townsend, and Hadlock, Washington. In accordance with the Purchase and Assumption Agreement, dated as of September 1, 2015, by and between Bank of America, 1st Security Bank acquired approximately $186.4 million of deposits, $1.1 million of performing loans and the bank facilities and certain other assets of the acquired branches. In consideration of the purchased assets and transferred liabilities, 1st Security Bank paid (a) the recorded investment of the loans acquired, (b) the net book value, or approximately $1.1 million , for the bank facilities and certain assets located at the acquired branches, (c) a deposit premium of 2.5% on substantially all of the deposits assumed, which equated to approximately $4.8 million . The acquisition settled by Bank of America paying cash of $180.4 million to 1st Security Bank for the difference between these amounts and the total deposits assumed. The branch purchase was accounted for under the acquisition method in accordance with ASC 805, “ Business Combinations ,” and accordingly the assets and liabilities were recorded at their fair values on the date of acquisition. Determining the fair value of assets and liabilities is a complicated process involving significant judgment regarding methods and assumptions used to calculate estimated fair values. Fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition as information relative to closing date fair values become available. The following table summarizes the estimated fair values of assets acquired and liabilities assumed at the date of acquisition. January 22, 2016 Acquired Book Value Fair Value Adjustments Amount Recorded (In thousands) Assets Cash and cash equivalents $ 180,356 $ — $ 180,356 Loans receivable 417 — 417 Premises and equipment, net 697 267 (1) 964 Accrued interest receivable 2 — 2 Core deposit intangible — 2,139 (2) 2,139 Goodwill — 2,412 (3) 2,412 Other assets 103 — 103 Total assets acquired $ 181,575 $ 4,818 $ 186,393 Liabilities Deposits $ 186,364 $ — 186,364 Accrued interest payable 7 — 7 Other liabilities 22 — 22 Total liabilities assumed $ 186,393 $ — $ 186,393 Explanation of Fair Value Adjustments (1) The fair value adjustment represents the difference between the fair value of the acquired branches and the book value of the assets acquired. The Company utilized third party appraisals to assist in the determination of fair value. (2) The fair value adjustment represents the value of the core deposit base assumed in the acquisition based on a study performed by an independent consulting firm. This amount was recorded by the Company as an identifiable intangible asset and will be amortized as an expense on a double-declining balance over the average life of the core deposit base, which is estimated to be nine years. (3) The fair value adjustment represents the value of the goodwill calculated from the acquisition based on the purchase price, less the fair value of assets acquired net of liabilities assumed. Included in noninterest expense for the year ended December 31, 2015 was approximately $876,000 in acquisition related expenses.

Basis of Presentation and Sum27

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Financial Statement Presentation	Financial Statement Presentation - The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and with prevailing practices within the banking and securities industries. In preparing such financial statements, management is required to make certain estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the balance sheet and the reported amounts of revenues and expenses for the reporting period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan and lease losses, fair value of financial instruments, the valuation of servicing rights, and the deferred income taxes . Amounts presented in the consolidated financial statements and footnote tables are rounded and presented in thousands of dollars except per share amounts. In the narrative footnote discussion, amounts are rounded and presented in millions of dollars to one decimal point if the amounts are above $ 1.0 million . Amounts below $ 1.0 million are rounded and presented to the nearest thousands. Certain prior year amounts have been reclassified to conform to the 2015 presentation with no change to net income or stockholders' equity previously reported.
Conversion and Change in Corporate Form
Use of Estimates
Principles of consolidation	Principles of Consolidation - The consolidated financial statements include the accounts of FS Bancorp, Inc. and its wholly owned subsidiary, 1st Security Bank of Washington. All material intercompany accounts have been eliminated in consolidation.
Cash and Cash Equivalents	Cash and Cash Equivalents - Cash and cash equivalents include cash and due from banks, and interest-bearing balances due from other banks and the Federal Reserve Bank of San Francisco ("FRB") and have a maturity of 90 days or less at the time of purchase. At December 31, 2015 the Company had no cash and due from banks and interest-bearing deposits at other financial institutions in excess of Federal Deposit Insurance Corporation ("FDIC") insured limits and at December 31, 2014, the Company had cash and due from banks and interest-bearing deposits at other financial institutions in excess of FDIC insured limits. Because the Company places these deposits with major financial institutions and monitors the financial condition of these institutions, management believes the risk of loss to any deposits in excess of FDIC limits to be minimal.
Securities Available-for-Sale	Securities Available-for-Sale - Securities available-for-sale consist of debt securities that the Company has the intent and ability to hold for an indefinite period, but not necessarily to maturity. Such securities may be sold to implement the Company’s asset/liability management strategies and in response to changes in interest rates and similar factors. Securities available-for-sale are reported at fair value. Unrealized holding gains and losses, net of the related deferred tax effect, are reported as a net amount in a separate component of equity entitled accumulated other comprehensive income. Unrealized losses that are deemed to be other than temporary are reflected in results of operations. Any declines in the values of these securities that are considered to be other-than-temporary-impairment (“OTTI”) and credit-related are recognized in earnings. Noncredit-related OTTI on securities not expected to be sold is recognized in other comprehensive income. The review for OTTI is conducted on an ongoing basis and takes into account the severity and duration of the impairment, recent events specific to the issuer or industry, fair value in relationship to cost, extent and nature of change in fair value, creditworthiness of the issuer including external credit ratings and recent downgrades, trends and volatility of earnings, current analysts’ evaluations, and other key measures. In addition, the Company does not intend to sell the securities and it is more likely than not that we will not be required to sell the securities before recovery of their amortized cost basis. In doing this, we take into account our balance sheet management strategy and consideration of current and future market conditions. Realized gains and losses on securities available-for-sale, determined using the specific identification method, are included in results of operations. Amortization of premium and accretion of discounts are recognized in interest income over the period to maturity.
Federal Home Loan Bank Stock	The Bank’s investment in FHLB stock is carried at par value ( $100 per share) because the shares can only be redeemed with the FHLB at par. The Bank is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages and FHLB advances. Stock redemptions are at the discretion of the FHLB upon five years ’ prior notice for FHLB Class B stock or six months notice for FHLB Class A stock to the FHLB. FHLB stock is carried at cost and is subject to recoverability testing annually.
Loans Held for Sale	Loans Held for Sale - The Bank records all mortgage loans held-for-sale at fair value. Fair value is determined by outstanding commitments from investors or current investor yield requirements calculated on the aggregate loan basis. Origination fees and costs are recognized in earnings at the time of origination. Mortgage loans held-for-sale are sold with the mortgage service rights released by the Bank. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loans sold. All sales are made without recourse. Derivatives - Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free-standing derivatives. The fair value of the interest rate lock is recorded at the time the commitment to fund the mortgage loan is executed and is adjusted for the expected exercise of the commitments to fund the loans, the Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest on the loan is locked. Changes in the fair values of these derivatives are included in other noninterest income on the Consolidated Statements of Income and included in gain on sale of loans.
Loans Receivable, Net	Loans Receivable - Loans receivable, are stated at the amount of unpaid principal reduced by an allowance for loan losses and net deferred fees or costs. Interest on loans is calculated using the simple interest method based on the daily balance of the principal amount outstanding and is credited to income as earned. Loan fees, net of direct origination costs, are deferred and amortized over the life of the loan using the effective yield method. Interest on loans is accrued daily based on the principal amount outstanding. Generally, the accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due or when they are past due 90 days as to either principal or interest (based on contractual terms), unless they are well secured and in the process of collection. All interest accrued but not collected for loans that are placed on non-accrual status or charged off are reversed against interest income. Subsequent collections on a cash basis are applied proportionately to past due principal and interest, unless collectability of principal is in doubt, in which case all payments are applied to principal. Loans are returned to accrual status when the loan is deemed current, and the collectability of principal and interest is no longer doubtful, or, generally, when the loan is less than 90 days delinquent, and performing according to contractual terms after a period of six months performance. The Company charges fees for originating loans. These fees, net of certain loan origination costs, are deferred and amortized to income, on the level-yield basis, over the loan term. If the loan is repaid prior to maturity, the remaining unamortized net deferred loan origination fee is recognized in income at the time of repayment. The Company has defined its loan portfolio into three segments that reflect the structure of the lending function, the Company’s strategic plan and the manner in which management monitors performance and credit quality. The three loan portfolio segments are: (a) Real Estate Loans, (b) Consumer Loans and (c) Commercial Business Loans. Each of these segments is disaggregated into classes based on the risk characteristics of the borrower and/or the collateral type securing the loan. Consumer, Home Equity and One-to-Four-Family Real Estate Loans Homogeneous loans are risk rated based upon the FDIC's Uniform Retail Credit Classification and Account Management Policy. Loans classified under this policy at the Company are consumer loans which include indirect home improvement, recreational, automobile, direct home improvement and other consumer, and one-to-four-family first and second liens. Under the Uniform Retail Credit Classification Policy, loans that are current or less than 90 days past due are graded “Pass” and risk graded " 4 " internally. Loans that are past due more than 90 days are classified “Substandard” risk graded " 8 " internally. Closed-end loans that are 120 days past due, and open-end loans that are 180 days past due are charged off based on the value of the collateral less cost to sell.
Impaired Loans	Impaired Loans - A loan is considered impaired when it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the original or modified terms of the loan agreement. Impaired loans are measured on a loan by loan basis based on the estimated fair value of the collateral less estimated cost to sell if the loan is considered collateral dependent. Impaired loans not considered to be collateral dependent are measured based on the present value of expected future cash flows. The categories of non-accrual loans and impaired loans overlap, although they are not coextensive. The Company considers all circumstances regarding the loan and borrower on an individual basis when determining whether an impaired loan should be placed on non-accrual status, such as the financial strength of the borrower, the collateral value, reasons for delay, payment record, the amount of past due and the number of days past due. Loans that experience insignificant payment delays and payment shortfalls are generally not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of shortfall in relation to the principal and interest owed.
Allowance for Loan Losses	Allowance for Loan Losses - The allowance for loan losses is maintained at a level considered adequate to provide for probable losses on existing loans based on evaluating known and inherent risks in the loan portfolio. The allowance is reduced by loans charged-off and increased by provisions charged to earnings and recoveries on loans previously charged-off. The allowance is based on management’s periodic, systematic evaluation of factors underlying the quality of the loan portfolio including changes in the size and composition of the loan portfolio, the estimated value of any underlying collateral, actual loan loss experience, current economic conditions, and detailed analysis of individual loans for which full collectability may not be assured. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. While management uses the best information available to make its estimates, future adjustments to the allowance may be necessary if there is a significant change in economic and other conditions. The appropriateness of the allowance for loan losses is estimated based on these factors and trends identified by management at the time the financial statements are prepared. When available information confirms that specific loans or portions thereof are uncollectible, these amounts are charged-off against the allowance for loan losses. The existence of some or all of the following criteria will generally confirm that a loss has been incurred: the loan is significantly delinquent and the borrower has not evidenced the ability or intent to bring the loan current; the Company has no recourse to the borrower, or if it does, the borrower has insufficient assets to pay the debt; the estimated fair value of the loan collateral is significantly below the current loan balance, and there is little or no near-term prospect for improvement. A provision of loan losses is charged against income and added to the allowance for loan losses based on regular assessment of the loan portfolio. The allowance for loan losses is allocated to certain loan categories based on the relative risk characteristics, asset classifications, and actual loss experience within the loan portfolio. Although management has allocated the allowance for loan losses to various loan portfolio segments, the allowance is general in nature and is available for the loan portfolio in its entirety. The ultimate recovery of all loans is susceptible to future market factors beyond the Company’s control. These factors may result in losses or recoveries differing significantly from those provided for in the financial statements. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations.
Reserve for Unfunded Loan Commitments and Letters of Credit	Reserve for Unfunded Loan Commitments - The reserve for unfunded loan commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to these unfunded credit facilities. The determination of the adequacy of the reserve is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. The reserve for unfunded loan commitments is included in other liabilities on the balance sheet, with changes to the balance charged against noninterest expense. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the amount of the total commitments do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate, and income-producing commercial properties.
Premises and Equipment, Net	Premises and Equipment, Net - Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The estimated useful lives used to compute depreciation include building and building improvements from 25 to 40 years and furniture, fixtures, and equipment from 3 to 10 years. Leasehold and tenant improvements are amortized using the straight-line method over the lesser of useful life or the life of the related lease. Depreciation and amortization expense for these assets totaled $ 1.2 million and $ 1.1 million for the years ended December 31, 2015 and 2014, respectively. Gains or losses on dispositions are reflected in results of operations.
Other Real Estate Owned and Other Repossessed Items
Transfers of Financial Assets and Mortgage Servicing Rights	Transfers of Financial Assets - Transfers of an entire financial asset, a group of entire financial assets, or participating interest in an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Servicing Rights - Servicing assets are recognized as separate assets when rights are acquired through purchase or through sale of financial assets. Generally, purchased servicing rights are capitalized at the cost to acquire the rights. For sales of mortgage, commercial and consumer loans, a portion of the cost of originating the loan is allocated to the servicing right based on relative fair value. Fair value is based on market prices for comparable mortgage, commercial, or consumer servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds, and default rates and losses. Servicing assets are evaluated quarterly for impairment based upon the fair value of the rights as compared to amortized cost. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type, and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranches. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income. Capitalized servicing rights are stated separately on the consolidated balance sheets and are amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets.
Income Taxes	Income Taxes - The Company files a consolidated federal income tax return. Deferred federal income taxes result from temporary differences between the tax basis of assets and liabilities, and their reported amounts in the financial statements. These will result in differences between income for tax purposes and income for financial reporting purposes in future years. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established to reduce the net recorded amount of deferred tax assets if it is determined to be more likely than not, that all or some portion of the potential deferred tax asset will not be realized. The Financial Accounting Standards Board (“FASB”) issued guidance related to accounting for uncertainty in income taxes. The guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It is the Company’s policy to record any penalties or interest arising from federal or state taxes as a component of income tax expense.
Earnings Per Share	reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. For purposes of computing basic and dilutive EPS, ESOP shares that have been committed to be released are outstanding and ESOP shares that have not been committed to be released shall not be considered outstanding.
Comprehensive Income (Loss)	Comprehensive Income (Loss) - Comprehensive income (loss) is comprised of net income and other comprehensive income (loss). Other comprehensive income (loss) includes items recorded directly to equity, such as unrealized holding gains and losses on securities available-for-sale.
Restricted Assets	Restricted Assets - Federal Reserve regulations require that the Bank maintain reserves in the form of cash on hand and deposit balances with the FRB, based on a percentage of deposits.
Marketing and Advertising Costs	Marketing and Advertising Costs - The Company records marketing and advertising costs as expenses as they are incurred.
Employee Stock Ownership Plan (ESOP)	Employee Stock Ownership Plan On January 1, 2012, the Company established an ESOP for eligible employees of the Company and the Bank. Employees of the Company and the Bank who have been credited with at least 1000 hours of service during a 12 -month period are eligible to participate in the ESOP.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation - Compensation cost is recognized for stock options and restricted stock awards, based on the fair value of these awards at the grant date. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company's common stock at the grant date is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.
401(k) Plan	401(k) Plan The Company has a salary deferral 401(k) Plan covering substantially all of its employees. Employees are eligible to participate in the 401(k) plan at the date of hire if they are 18 years of age. Eligible employees may contribute through payroll deductions and are 100% vested at all times in their deferral contributions account. The Company matches 100% for contributions between 1% and 3% , and 50% for contributions between 4% and 5% . There was a $589,000 and $436,000 matching contribution for the years ended December 31, 2015 and 2014, respectively.
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS In January 2015, the FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20) . The objective of this ASU is to simplify the income statement presentation requirements in Subtopic 225-20 by eliminating the concept of extraordinary items. Extraordinary items are events and transactions that are distinguished by their unusual nature and by the infrequency of their occurrence. Eliminating the extraordinary classification simplifies income statement presentation by altogether removing the concept of extraordinary items from consideration. This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015 with early adoption permitted. The Company does not expect this ASU to have a material impact on the Company's consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis , which is intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). The ASU focuses on simplifying the consolidation evaluation for reporting organizations that are required to evaluate whether they should consolidate certain legal entities by reducing the number of consolidation model from four to two, among other changes. The ASU will be effective for periods beginning after December 31, 2015, while early adoption is permitted. The Company does not expect this ASU to have a material impact on the Company's consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs . The amendments in this ASU require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected. The ASU is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. ASU No. 2015-03 should be applied on a retrospective basis. The Company is currently evaluating the impacts of this ASU on the Company's consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement . The amendments in this ASU provide guidance to customers in cloud computing arrangements about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement does include a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The amendments are effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. This ASU is not expected to have a material effect on the Company's consolidated financial statements. In June 2015, FASB issued ASU No. 2015-10, Technical Corrections and Improvements . On November 10, 2010 FASB added a standing project that will facilitate the FASB Accounting Standards Codification ("Codification") updates for technical corrections, clarifications, and improvements. These amendments are referred to as Technical Corrections and Improvements. Maintenance updates include non-substantive corrections to the Codification, such as editorial corrections, various link-related changes, and changes to source fragment information. This update contains amendments that will affect a wide variety of Topics in the Codification. The amendments in this ASU will apply to all reporting entities within the scope of the affected accounting guidance and generally fall into one of four categories: amendments related to differences between original guidance and the Codification, guidance clarification and reference corrections, simplification, and minor improvements. In summary, the amendments in this ASU represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have a significant effect on current accounting practice. Transition guidance varies based on the amendments in this ASU. The amendments in this ASU that require transition guidance are effective for fiscal years and interim reporting periods after December 15, 2015. Early adoption is permitted including adoption in an interim period. All other amendments are effective upon the issuance of this ASU. ASU 2015-10 did not have a material impact on the Company's consolidated financial statements. In July 2015, the FASB issued ASU 2015-12, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965): (Part I) Fully Benefit-Responsive Investment Contracts, (Part II) Plan Investment Disclosures, (Part III) Measurement Date Practical Expedient (consensuses of the FASB Emerging Issues Task Force) . The amendments of this ASU (i) require fully benefit-responsive investment contracts to be measured, presented and disclosed only at contract value, not fair value; (ii) simplify the investment disclosure requirements; and (iii) provide a measurement date practical expedient for employee benefit plans. This ASU is effective for fiscal years beginning after December 15, 2015, although earlier adoption is permitted. This ASU is not expected to have a material effect on the Company's consolidated financial statements. In July 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers, deferring the effective date of the new revenue standard by one year . The standard also allows entities to choose to adopt the standard as of the original effective date. The FASB decided, based on its outreach to various stakeholders and the forthcoming amendments to the new revenue standard, that a deferral is necessary to provide adequate time to effectively implement the new revenue standard. In August 2015, the FASB issued ASU No. 2015-15, Interest-Imputation of Interest (Subtopic 835-30), Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements . The ASU provides guidance not previously included in ASU 2015-03 regarding debt issuance related to line-of-credit arrangements. The amendment allows an entity to present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs over the term of the line-of-credit arrangement, regardless if there are any outstanding borrowings on the line-of-credit arrangement. The amendment is effective for fiscal years beginning after December 15, 2015. This ASU is not expected to have a material effect on the Company's consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805) . This ASU simplifies the accounting for adjustments made to provisional amounts recognized in a business combination during the measurement period. The amendments in this ASU require that the acquirer recognize the adjustments to provisional amounts in the reporting period in which the adjustment amount is determined. The acquirer must also record in the same period's financial statements, the effect on earnings of changes in depreciation, amortization or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. This ASU has a potential impact on the Company, and the Company is currently evaluating the impact of this ASU on the Company's consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17 , Income Taxes, Balance Sheet Classification of Deferred Taxes . ASU 2015-17 simplifies the presentation of deferred income taxes by requiring deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. Prior to this amendment, entities were required to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position based on the classification of the related asset or liability for financial reporting, or by the expected reversal date of the temporary difference. The ASU is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The adoption of ASU 2015-17 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 amendments in this ASU require the exit price notion be used 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 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. The adoption of ASU 2016-02 is not expected to have a material impact on the Company's consolidated financial statements.
Securities Available For Sale	There were 17 investments with unrealized losses of less than one year and eight investments with unrealized losses of more than one year at December 31, 2015. There were eight investments with unrealized losses of less than one year and 13 investments with unrealized losses of more than one year at December 31, 2014. The unrealized losses associated with these investments are believed to be caused by changing market conditions that are considered to be temporary and the Company does not intend to sell these securities, and is not likely to be required to sell these securities.

Credit Quality Indicators	Credit Quality Indicators As part of the Company’s on-going monitoring of credit quality of the loan portfolio, management tracks certain credit quality indicators including trends related to (i) the risk grading of loans, (ii) the level of classified loans, (iii) net charge-offs, (iv) non-performing loans and (v) the general economic conditions in the Company’s markets. The Company utilizes a risk grading matrix to assign a risk grade to its real estate and commercial business loans. Loans are graded on a scale of 1 to 10 , with loans in risk grades 1 to 6 considered “Pass” and loans in risk grades 7 to 10 are reported as classified loans in the Company's allowance for loan loss analysis. A description of the 10 risk grades is as follows: • Grades 1 and 2 - These grades include loans to very high quality borrowers with excellent or desirable business credit. • Grade 3 - This grade includes loans to borrowers of good business credit with moderate risk. • Grades 4 and 5 - These grades include “Pass” grade loans to borrowers of average credit quality and risk. • Grade 6 - This grade includes loans on management’s “Watch” list and is intended to be utilized on a temporary basis for “Pass” grade borrowers where frequent and thorough monitoring is required due to credit weaknesses and where significant risk-modifying action is anticipated in the near term. • Grade 7 - This grade is for “Other Assets Especially Mentioned (OAEM)” in accordance with regulatory guidelines and includes borrowers where performance is poor or significantly less than expected. • Grade 8 - This grade includes “Substandard” loans in accordance with regulatory guidelines which represent an unacceptable business credit where a loss is possible if loan weakness is not corrected. • Grade 9 - This grade includes “Doubtful” loans in accordance with regulatory guidelines where a loss is highly probable. • Grade 10 - This grade includes “Loss” loans in accordance with regulatory guidelines for which total loss is expected and when identified are charged off.
Loan Commitments	The Company is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized on the balance sheet. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments.

Fair Value Inputs, Assets, Quantitative Information [Table Text Block]	Fair value adjustments to servicing rights were mainly due to market based assumptions associated with discounted cash flows, loan prepayment speeds, and changes in interest rates. A significant change in prepayments of the loans in the servicing portfolio could result in significant changes in the valuation adjustments, thus creating potential volatility in the carrying amount of servicing rights. Valuation assumptions used in determining the fair value of commercial and consumer servicing rights were excluded from the tables below due to immateriality, mortgage servicing rights ("MSR") are included at the dates indicated as follows: At December 31, Key assumptions: 2015 2014 Weighted average discount rate 8.5 % 8.5 % Conditional prepayment rate ("CPR") 12.2 % 13.2 % Weighted average life in years 6.4 6.1

Schedule of Accounting Policies [Line Items]
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation - Compensation cost is recognized for stock options and restricted stock awards, based on the fair value of these awards at the grant date. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company's common stock at the grant date is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.
