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” or “1st Security 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 11 branches and seven loan production offices in suburban communities in the greater Puget Sound area which includes Snohomish, King, Pierce, Jefferson, Kitsap, and Clallam counties, 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 Bank acquired four retail bank branches from Bank of America, National Association (“Bank of America”) (two in Clallam and two in Jefferson counties) on January 22, 2016, and these branches opened as 1st Security Bank branches on January 25, 2016. 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”), 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 is maintained for the benefit of eligible savings account holders at 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 Company’s assets, liabilities, and equity unchanged as a result. Financial Statement Presentation - The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (“SEC”). It is recommended that these unaudited interim consolidated financial statements be read in conjunction with the Company’s Annual Report on Form 10-K with all of the audited information and footnotes required by U.S. GAAP for complete financial statements for the year ended December 31, 2016, as filed with the SEC on March 16, 2017. In the opinion of management, all normal adjustments and recurring accruals considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. The results for the three months ended March 31, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017, or any other future period. The preparation of financial statements, in conformity with U.S. GAAP, requires management to make estimates and assumptions that affect amounts reported in the financial statements. Actual results could differ from these 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, and the valuation of servicing rights. 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 in dollars to the nearest thousands. Certain prior year amounts have been reclassified to conform to the 2017 presentation with no change to consolidated 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 operates as two segments organized by two lines of business: commercial and consumer banking segment and home lending segment. The Company’s business segments are determined based on the products and services provided, as well as the nature of the related business activities, and they reflect the manner in which financial information is regularly reviewed for the purpose of allocating resources and evaluating performance of the Company’s businesses. The results for these business segments are based on management’s accounting process, which assigns income statement items and assets to each responsible operating segment. This process is dynamic and is based on management’s view of the Company’s operations. See Note 15 - Business Segments. Subsequent Events - The Company has evaluated events and transactions subsequent to March 31, 2017, for potential recognition or disclosure. RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which creates Topic 606 and supersedes Topic 605, Revenue Recognition. In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606) , which postponed the effective date of 2014-09. In March 2016, the FASB issued ASU 2016-08, R evenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , which amended the principal versus agent implementation guidance set for in ASU 2014-09. Among other things, ASU 2016-08 clarifies that an entity should evaluate whether it is the principal or the agent for each specified good or service promised in a contract with a customer. In April 2016, the FASB issued ASU No. 2016-10, R evenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing . The ASU amends certain aspects of the guidance set forth in the FASB's new revenue standard related to identifying performance obligations and licensing implementation. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In general, the new guidance requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which provides clarifying guidance in certain narrow areas and adds some practical expedients, but does not change the core revenue recognition principle in Topic 606. The ASU is effective for public entities for interim and annual periods beginning after December 15, 2017; early adoption is not permitted. For financial reporting purposes, the ASU allows for either full retrospective adoption, meaning the ASU is applied to all of the periods presented, or modified retrospective adoption, meaning the ASU is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. As a bank holding company, key revenue sources, such as interest income have been identified as out of the scope of this new guidance. The Company’s preliminary analysis suggests that the adoption of this accounting standard is not expected to have a material impact on the Company’s consolidated financial statements as substantially all of the Company’s other revenues are also excluded from the scope of the new guidance. New accounting guidance related to the adoption of this standard continues to be released by the FASB, which could impact the Company’s preliminary analysis of materiality and may change the preliminary conclusions reached as to the application of this new guidance. 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. Once adopted, we expect to report higher assets and liabilities as a result of including right-of-use assets and lease liabilities related to certain banking offices and certain equipment under noncancelable operating lease agreements, however, based on current leases, the adoption of ASU 2016-02 is expected to increase our Consolidated Balance Sheets by less than 5% and not to have a material impact on our regulatory capital ratios. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. Organizations will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. The ASU requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early application will be permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact of this ASU on the Company’s consolidated financial statements. Once adopted, we expect our allowance for loan losses to increase, however, until our evaluation is complete the magnitude of the increase will be unknown. In January 2017, the FASB issued ASU 2017-04 - Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The ASU was issued to simplify the subsequent measurement of goodwill and the amendment eliminates Step 2 from the goodwill impairment test. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU is effective for annual reporting periods beginning after December 31, 2019. Early adoption of the ASU is permitted. The Company does not expect this ASU to have a material impact on the Company's consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities . The ASU shortens the amortization period for certain callable debt securities held at a premium. The standard will take effect for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of ASU No. 2017-08 is not expected to have a material impact on the Company's consolidated financial statements.

Business Combination [Abstract]
Business Combination	BUSINESS COMBINATION On January 22, 2016, the Company’s wholly-owned subsidiary, 1st Security Bank, completed the purchase of four branches (“Branch Purchase”) from Bank of America. The Branch Purchase included 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, between Bank of America and 1st Security Bank, the Bank acquired $ 186.4 million of deposits, a small portfolio of performing loans, two owned bank branches, three leases associated with the bank branches and parking facilities and certain other assets of the branches. In consideration of the purchased assets and transferred liabilities, 1st Security Bank paid (a) the unpaid principal balance and accrued interest of $ 419,000 for the loans acquired, (b) the net book value, or approximately $ 778,000 , for the bank facilities and certain other assets associated with the acquired branches, and (c) a deposit premium of 2.50% on substantially all of the deposits assumed, which equated to approximately $ 4.8 million. The transaction was settled with 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 of accounting and accordingly, the assets and liabilities were recorded at their fair values on January 22, 2016, 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. During the second quarter of 2016, the Company completed a re-evaluation of the core deposit intangible because a portion of the core deposits were excluded from the original valuation. The updated valuation of the core deposit intangible increased the fair value adjustment by $ 100,000 to $ 2.2 million from $ 2.1 million resulting in a decrease of $ 100,000 to the fair value adjustment of goodwill. The impact to consolidated net income was an increase in the amortization of the core deposit intangible for the six months ended June 30, 2016 of $ 6,000 and was not considered material to the consolidated financial statements. 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 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 — 2,239 (2) 2,239 Goodwill — 2,312 (3) 2,312 Other assets 103 — 103 Total assets acquired $ 181,575 $ 4,818 $ 186,393 Liabilities Deposits: Noninterest-bearing accounts $ 79,966 $ — $ 79,966 Interest-bearing accounts 106,398 — 106,398 Total 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 valuations but did not receive 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 Branch Purchase 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 an accelerated basis 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 purchase based on the purchase price, less the fair value of assets acquired net of liabilities assumed. Goodwill - The acquired goodwill represents the excess purchase price over the estimated fair value of the net assets acquired and was recorded at $2.3 million on January 22, 2016. The following table summarizes the aggregate amount recognized for each major class of assets acquired and liabilities assumed by 1st Security Bank in the Branch Purchase on January 22, 2016: At January 22, 2016 Purchase price (1) $ 6,015 Recognized amounts of identifiable assets acquired and (liabilities assumed), at fair value: Cash and cash equivalents 186,371 Acquired loans 417 Premises and equipment, net 964 Accrued interest receivable 2 Core deposit intangible 2,239 Other assets 103 Deposits (186,364 ) Accrued interest payable (7 ) Other liabilities (22 ) Total fair value of identifiable net assets 3,703 Goodwill $ 2,312 (1) Purchase price includes premium paid on the deposits, the aggregate net book value of all assets acquired, and the unpaid principal and accrued interest on loans acquired. Core deposit intangible The core deposit intangible represents the fair value of the acquired core deposit base. The core deposit intangible will be amortized on an accelerated basis over approximately nine years. Total amortization expense was $100,000 for the three months ended March 31, 2017, and $ 102,000 for the same period in 2016. Amortization expense for core deposit intangible is expected to be as follows at March 31, 2017: 2017 $ 300 2018 307 2019 235 2020 181 2021 166 Thereafter 428 Total $ 1,617

Investment securities that were in an unrealized loss position at March 31, 2017 and December 31, 2016 are presented in the following tables, based on the length of time individual securities have been in an unrealized loss position. Management believes that these securities are only temporarily impaired due to changes in market interest rates or the widening of market spreads subsequent to the initial purchase of the securities, and not due to concerns regarding the underlying credit of the issuers or the underlying collateral.

There were 48 investments with unrealized losses of less than one year, and two investments with unrealized losses of more than one year at December 31, 2016. The unrealized losses associated with these investments are believed to be caused by changes in market interest rates that are considered to be temporary and the Company does not intend to sell the securities, and it is not likely to be required to sell these securities prior to maturity. No other-than-temporary impairment was recorded for the three months ended March 31, 2017 or for the year ended December 31, 2016. The contractual maturities of securities available-for-sale at March 31, 2017 and December 31, 2016 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 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, solar, marine, 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 rated “4” or “5” internally. Loans that are past due more than 90 days are classified “Substandard” and risk rated “8” internally until the loan has demonstrated consistent performance, typically six months of contractual payments. 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 one TDR loan on accrual and included in impaired loans at both March 31, 2017 and December 31, 2016, with a balance of $ 56,000 and $ 57,000 , respectively, which was a one-to-four-family loan. The Company had no commitments to lend additional funds on this TDR loan at March 31, 2017. For the three months ended March 31, 2017 and 2016 there were no TDR loans that were modified in the previous 12 months that subsequently defaulted in the reporting period. There was no loans held for investment property in the process of foreclosure at March 31, 2017. At December 31, 2016, there was a $ 43,000 mortgage loan collateralized by residential real estate property in the process of foreclosure.

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 loans serviced for others were $1.0 billion and $977.1 million at March 31, 2017 and December 31, 2016, respectively and are carried at the lower of cost or market. The following table summarizes servicing rights activity and the respective book value at or for the three months ended March 31, 2017 and 2016: At or For the Three Months Ended 2017 2016 Beginning balance $ 8,459 $ 5,811 Additions 990 613 Servicing rights amortized (509 ) (321 ) (Impairment) recovery on servicing rights (1 ) 1 Ending balance $ 8,939 $ 6,104 The fair market value of the servicing rights’ assets was $ 12.6 million and $ 11.7 million at March 31, 2017 and December 31, 2016, respectively. Fair value adjustments to servicing rights are 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. The following provides valuation assumptions used in determining the fair value of mortgage servicing rights (“MSR”) at the dates indicated: At March 31, Key assumptions: 2017 2016 Weighted average discount rate 9.5 % 9.5 % Conditional prepayment rate (“CPR”) 8.7 % 15.4 % Weighted average life in years 7.9 5.4 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 March 31, 2017 and December 31, 2016 were as follows: March 31, 2017 December 31, 2016 Aggregate portfolio principal balance $ 1,038,791 $ 973,139 Weighted average rate of note 3.9 % 3.9 % At March 31, 2017 Base 0.5% Adverse Rate Change 1.0% Adverse Rate Change Conditional prepayment rate 8.7 % 12.8 % 19.7 % Fair value MSR $ 12,551 $ 10,634 $ 8,381 Percentage of MSR 1.2 % 1.0 % 0.8 % Discount rate 9.5 % 10.0 % 10.5 % Fair value MSR $ 12,551 $ 12,278 $ 12,016 Percentage of MSR 1.2 % 1.2 % 1.2 % At December 31, 2016 Base 0.5% Adverse Rate Change 1.0% Adverse Rate Change Conditional prepayment rate 8.8 % 12.8 % 20.2 % Fair value MSR $ 11,735 $ 9,991 $ 7,808 Percentage of MSR 1.2 % 1.0 % 0.8 % Discount rate 9.5 % 10.0 % 10.5 % Fair value MSR $ 11,735 $ 11,480 $ 11,235 Percentage of MSR 1.2 % 1.2 % 1.2 % The above table shows the sensitivity to market rate changes for the par rate coupon for a conventional one-to-four-family FNMA/FHLMC/GNMA/FHLB serviced home loan. The above table references a 50 basis point and 100 basis point decrease in note rates. 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 at a particular point in time. Those assumptions may not be appropriate if they are applied to a different point in time. The Company recorded $654,000 and $419,000 of contractually specified servicing fees, late fees, and other ancillary fees resulting from servicing of mortgage, commercial and consumer loans for the three months ended March 31, 2017 and 2016, respectively. The income, net of amortization, is reported in noninterest income.

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 for reporting purposes under U.S. GAAP. 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 at the dates indicated: March 31, 2017 Fair Value Notional Asset Liability Fallout adjusted interest rate lock commitments with customers $ 59,954 $ 1,437 $ — Mandatory and best effort forward commitments with investors 21,290 — 19 Forward TBA mortgage-backed securities 70,500 — 346 TBA mortgage-backed securities forward sales paired off with investors 32,500 — 41 December 31, 2016 Fair Value Notional Asset Liability Fallout adjusted interest rate lock commitments with customers $ 33,289 $ 818 $ — Mandatory and best effort forward commitments with investors 23,536 177 — Forward TBA mortgage-backed securities 53,000 495 — TBA mortgage-backed securities forward sales paired off with investors 44,000 747 — 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 resulted in a net (loss) gain of ($495,000) and $2.3 million for the three months ended March 31, 2017 and 2016, respectively.

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. The following table provides a summary of the Company’s commitments at March 31, 2017 and December 31, 2016: COMMITMENTS TO EXTEND CREDIT March 31, December 31, REAL ESTATE LOANS 2017 2016 Commercial $ 107 $ 108 Construction and development 68,096 57,016 One-to-four-family (includes held for sale) 99,812 79,870 Home equity 29,289 26,129 Multi-family 427 426 Total real estate loans 197,731 163,549 CONSUMER LOANS 8,744 8,527 COMMERCIAL BUSINESS LOANS Commercial and industrial 45,748 31,775 Warehouse lending 64,217 51,102 Total commercial business loans 109,965 82,877 Total commitments to extend credit $ 316,440 $ 254,953 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 an 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 reserves for estimated losses from unfunded commitments of $220,000 at March 31, 2017 and $179,000 at December 31, 2016. 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 also sells one-to-four-family loans to the FHLB of Des Moines that require a limited level of recourse if the loans default and incur certain loss exposure. Specific to that recourse, the FHLB established a first loss account (“FLA”) related to the loans and required a credit enhancement (“CE”) obligation by the Bank to be utilized after the FLA is utilized. Based on loans sold through March 31, 2017, the total loans sold to the FHLB were $42.4 million with the FLA being $433,000 and the CE obligation at $1.1 million or 2.52% of the loans outstanding. Management has established a reserve of 10% of the outstanding CE, or $121,000 , which is a part of the off balance sheet reserve for loans sold. There were no outstanding delinquencies on the loans sold to the FHLB of Des Moines at March 31, 2017 and December 31, 2016. Contingent liabilities for loans held for sale - In the ordinary course of business, loans are sold with limited recourse against the Company and 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 payoff, early payment defaults, breach of representation or warranty, servicing errors, and/or 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 $ 886,000 and $ 955,000 to cover loss exposure related to these guarantees for one-to-four-family loans sold into the secondary market at March 31, 2017 and December 31, 2016, which is included in other liabilities in the Consolidated Balance Sheets. 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 his 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, Chief Operating Officer, Chief Lending Officer, and two Executive Vice Presidents of Home Lending. 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. The Bank received 7,158 shares of Class B common stock in Visa, Inc. as a result of the Visa initial public offering (“IPO”) in March 2008. These Class B shares of stock held by the Bank could be converted to Class A shares at a conversion rate of 1.6483 when all litigation pending as of the date of the IPO is concluded. However, at March 31, 2017, the date that litigation will be concluded cannot be determined. Until such time, the stock cannot be redeemed or sold by the Bank; therefore, it is not readily marketable and has a current carrying value of $0 . Visa, Inc. Class A stock’s market value at March 31, 2017 and 2016 was $88.87 per share and $76.48 per share, respectively. Due to 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 had no material pending legal actions at March 31, 2017.

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 Available-for-Sale - The fair value of securities available-for-sale are recorded 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. TBA mortgage-backed securities are fair valued on similar contracts in active markets (Level 2) while locks and forwards with customers and investors are fair valued using similar contracts in the market and changes in the market interest rates (Levels 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. Management will utilize discounted cash flow impairment for TDRs when the change in terms results in a discount to the overall cash flows to be received (Level 3). The following tables present securities available-for-sale measured at fair value on a recurring basis at March 31, 2017 and December 31, 2016: Securities Available-for-Sale At March 31, 2017 Level 1 Level 2 Level 3 Total U.S. agency securities $ — $ 11,961 $ — $ 11,961 Corporate securities — 7,556 — 7,556 Municipal bonds — 18,804 — 18,804 Mortgage-backed securities — 55,293 — 55,293 U.S. Small Business Administration securities — 13,627 — 13,627 Total $ — $ 107,241 $ — $ 107,241 Securities Available-for-Sale At December 31, 2016 Level 1 Level 2 Level 3 Total U.S. agency securities $ — $ 8,068 $ — $ 8,068 Corporate securities — 7,500 — 7,500 Municipal bonds — 15,264 — 15,264 Mortgage-backed securities — 45,195 — 45,195 U.S. Small Business Administration securities — 5,848 — 5,848 Total $ — $ 81,875 $ — $ 81,875 The following table presents mortgage loans held for sale measured at fair value on a recurring basis at March 31, 2017 and December 31, 2016: Mortgage Loans Held for Sale Level 1 Level 2 Level 3 Total March 31, 2017 $ — $ 40,008 $ — $ 40,008 December 31, 2016 $ — $ 52,553 $ — $ 52,553 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 March 31, 2017 and December 31, 2016: Interest Rate Lock Commitments with Customers Level 1 Level 2 Level 3 Total March 31, 2017 $ — $ — $ 1,437 $ 1,437 December 31, 2016 $ — $ — $ 818 $ 818 Individual Forward Sale Commitments with Investors Level 1 Level 2 Level 3 Total March 31, 2017 $ — $ (346 ) $ (19 ) $ (365 ) December 31, 2016 $ — $ 495 $ 177 $ 672 Paired Off Commitments with Investors Level 1 Level 2 Level 3 Total March 31, 2017 $ — $ (41 ) $ — $ (41 ) December 31, 2016 $ — $ 747 $ — $ 747 The following table presents impaired loans measured at fair value on a nonrecurring basis for which a nonrecurring change in fair value has been recorded during the reporting period.

Gains (losses) on forward sale commitments with investors carried at fair value are recorded within other noninterest income. Fair Values of Financial Instruments - 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). Bank-owned Life Insurance - The estimated fair value is equal to the cash surrender value of policies, net of surrender charges (Level 1). 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 Bank’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 for similarly sized issuances (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 following table provides estimated fair values of the Company’s financial instruments at March 31, 2017 and December 31, 2016: March 31, December 31, 2017 2016 Financial Assets Carrying Amount Fair Value Carrying Amount Fair Value Level 1 inputs: Cash and cash equivalents $ 46,055 $ 46,055 $ 36,456 $ 36,456 Certificates of deposit at other financial institutions 17,613 17,613 15,248 15,248 Level 2 inputs: Securities available-for-sale, at fair value 107,241 107,241 81,875 81,875 Loans held for sale, at fair value 40,008 40,008 52,553 52,553 FHLB stock, at cost 3,101 3,101 2,719 2,719 Accrued interest receivable 2,756 2,756 2,524 2,524 Individual forward sale commitments with investors — — 495 495 Paired off commitments with investors — — 747 747 Level 3 inputs: Loans receivable, gross 629,915 679,108 605,415 670,183 Servicing rights, held at lower of cost or fair value 8,939 12,557 8,459 11,741 Fair value interest rate locks with customers 1,437 1,437 818 818 Individual forward sale commitments with investors — — 177 177 Financial Liabilities Level 2 inputs: Deposits 758,014 769,317 712,593 718,970 Borrowings 10,269 10,249 12,670 12,660 Subordinated note 9,830 9,805 9,825 9,805 Accrued interest payable 185 185 192 192 Individual forward sale commitments with investors 346 346 — — Paired off commitments with investors 41 41 — — Level 3 inputs: Individual forward sale commitments with investors 19 19 — —

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	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 1,000 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, 2016, the ESOP paid the fifth annual installment of principal in the amount of $257,000 , plus accrued interest of $38,000 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 March 31, 2017 for the prior 90 days. These shares become outstanding for earnings per share 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 three months ended March 31, 2017 and 2016 was $237,000 and $160,000 , respectively. Shares held by the ESOP at March 31, 2017 and 2016 were as follows (shown as actual): Balances Balances at March 31, 2017 at March 31, 2016 Allocated shares 126,589 102,359 Committed to be released shares 6,480 6,480 Unallocated shares 123,125 149,046 Total ESOP shares 256,194 257,885 Fair value of unallocated shares (in thousands) $ 4,497 $ 3,671

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share are computed by dividing income available to common shareholders 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 earnings per share calculations, the ESOP shares committed to be released are included as outstanding shares for both basic and diluted earnings per share. The following table presents a reconciliation of the components used to compute basic and diluted earnings per share for the three months ended March 31, 2017 and 2016: At or For the Three Months Ended March 31, Numerator: 2017 2016 Net income (in thousands) $ 2,593 $ 1,661 Denominator: Basic weighted average common shares outstanding 2,872,317 2,947,841 Dilutive shares 189,680 84,773 Diluted weighted average common shares outstanding 3,061,997 3,032,614 Basic earnings per share $ 0.90 $ 0.56 Diluted earnings per share $ 0.85 $ 0.55

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 $191,000 and $193,000 for the three months ended March 31, 2017 and March 31, 2016, respectively. Stock Options The Plan authorizes the grant of stock options totaling 324,013 shares to Company directors and employees. Option awards were 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 permitted by the SEC 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 following table presents a summary of the Company’s stock option plan awards during the three months ended March 31, 2017 (shown as actual): Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term In Years Aggregate Intrinsic Value Outstanding at January 1, 2017 295,850 $ 16.89 7.36 $ 5,638,901 Granted — — — — Less exercised 5,763 16.89 — 126,995 Forfeited or expired — — — — Outstanding at March 31, 2017 290,087 $ 16.89 7.11 $ 5,929,378 Expected to vest, assuming a 0.31% annual forfeiture rate 289,435 $ 16.89 7.11 $ 5,916,055 Exercisable at March 31, 2017 99,887 $ 16.89 7.11 $ 2,041,690 At March 31, 2017, there was $484,000 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 2.1 years. Restricted Stock Awards The Plan authorizes the grant of restricted stock awards totaling 129,605 shares to Company directors and employees, and 125,105 shares were granted on May 8, 2014 at a grant date fair value of $16.89 per share. The remaining 4,500 restricted stock awards were granted January 1, 2016 at a grant date fair value of $26.00 per share. Compensation expense is recognized over the vesting period of the awards based on the fair value of the restricted stock. 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. The following table presents a summary of the Company’s nonvested awards during the three months ended March 31, 2017 (shown as actual): Nonvested Shares Shares Weighted-Average Grant-Date Fair Value Per Share Weighted-Average Grant-Date Fair Value Nonvested at January 1, 2017 68,763 $ 17.49 $ 1,202,401 Granted — — — Less vested 1,500 26.00 39,000 Forfeited or expired — — — Nonvested at March 31, 2017 67,263 $ 17.30 $ 1,163,401 At March 31, 2017, there was $696,000 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 2.0 years.

Regulatory Capital

Regulatory Capital Requirements [Abstract]
Regulatory Capital	REGULATORY CAPITAL The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines of the regulatory framework for prompt corrective action, the Bank must meet specific capital adequacy 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 classification is also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below) of Tier 1 capital (as defined in the regulations) to total average assets (as defined), and minimum ratios of Tier 1 total capital (as defined) and common equity Tier 1 (“CET 1”) capital to risk-weighted assets (as defined). The Bank must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the table below to be categorized as well capitalized. At March 31, 2017 and December 31, 2016, the Bank was categorized as well capitalized under applicable regulatory requirements. There are no conditions or events since that notification that management believes have changed the Bank’s category. Management believes, at March 31 2017, that the Company and the Bank met all capital adequacy requirements to which they were subject. The following table compares the Bank’s actual capital amounts and ratios at March 31, 2017 and December 31, 2016 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 Bank Only Actual At March 31, 2017 Amount Ratio Amount Ratio Amount Ratio Total risk-based capital (to risk-weighted assets) $ 95,360 13.77 % $ 55,385 8.00 % $ 69,232 10.00 % Tier 1 risk-based capital (to risk-weighted assets) $ 86,682 12.52 % $ 41,539 6.00 % $ 55,385 8.00 % Tier 1 leverage capital (to average assets) $ 86,682 10.38 % $ 33,396 4.00 % $ 41,745 5.00 % CET 1 capital (to risk-weighted assets) $ 86,682 12.52 % $ 31,154 4.50 % $ 45,001 6.50 % At December 31, 2016 Total risk-based capital (to risk-weighted assets) $ 93,309 13.87 % $ 53,813 8.00 % $ 67,266 10.00 % Tier 1 risk-based capital (to risk-weighted assets) $ 84,876 12.62 % $ 40,360 6.00 % $ 53,813 8.00 % Tier 1 leverage capital (to average assets) $ 84,876 10.33 % $ 32,862 4.00 % $ 41,078 5.00 % CET 1 capital (to risk-weighted assets) $ 84,876 12.62 % $ 30,270 4.50 % $ 43,723 6.50 % In addition to the minimum CET 1, Tier 1 and total capital ratios, the Bank has to maintain a capital conservation buffer consisting of additional CET 1 capital 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 was phased in beginning in January 2016 at 0.625% of risk-weighted assets and will increase each year until fully implemented to an amount equal to 2.5% of risk-weighted assets in January 2019. FS Bancorp, Inc. is a bank holding company subject to the 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, Inc. was subject to regulatory guidelines for bank holding companies with $1.0 billion or more in assets, at March 31, 2017, the Company would have exceeded all regulatory capital requirements. The regulatory capital ratios calculated for FS Bancorp, Inc. at March 31, 2017 were 9.7% for Tier 1 leverage-based capital, 11.6% for Tier 1 risk-based capital, 12.9% for total risk-based capital, and 11.6% for CET 1 capital ratio.

Business Segments

Segment Reporting [Abstract]
Business Segments	BUSINESS SEGMENTS The Company’s business segments are determined based on the products and services provided, as well as the nature of the related business activities, and they reflect the manner in which financial information is currently evaluated by management. This process is dynamic and is based on management’s current view of the Company’s operations and is not necessarily comparable with similar information for other financial institutions. We define our business segments by product type and customer segment which we have organized into two lines of business: commercial and consumer banking segment and home lending segment. We use various management accounting methodologies to assign certain income statement items to the responsible operating segment, including: • a funds transfer pricing (“FTP”) system, which allocates interest income credits and funding charges between the segments, assigning to each segment a funding credit for its liabilities, such as deposits, and a charge to fund its assets; • a cost per loan serviced allocation based on the number of loans being serviced on the balance sheet and the number of loans serviced for third parties; • an allocation based upon the square footage utilized by the home lending segment in Company owned locations; • an allocation of charges for services rendered to the segments by centralized functions, such as corporate overhead, which are generally based on the number of full time employees (“FTEs”) in each segment; and • an allocation of the Company’s consolidated income taxes which are based on the effective tax rate applied to the segment’s pretax income or loss. The FTP methodology is based on management’s estimated cost of originating funds including the cost of overhead for deposit generation. A description of the Company’s business segments and the products and services that they provide is as follows: Commercial and Consumer Banking Segment The commercial and consumer banking segment provides diversified financial products and services to our commercial and consumer customers through Bank branches, ATMs, online banking platforms, mobile banking apps, and telephone banking. These products and services include deposit products; residential, consumer, business and commercial real estate lending portfolios and cash management services. We originate consumer loans, commercial real estate loans, construction loans on residential and multi-family construction, and business loans. At March 31, 2017, our retail deposit branch network consisted of 11 branches in the Pacific Northwest. At March 31, 2017 and December 31, 2016, our deposits totaled $758.0 million and $712.6 million , respectively. This segment is also responsible for the management of our investment portfolio, and other assets of the Bank. Home Lending Segment The home lending segment originates one-to-four-family residential mortgage loans primarily for sale in the secondary markets as well as originating adjustable rate mortgage (“ARM”) loans held for investment. The majority of our mortgage loans are sold to or securitized by FNMA, FHLMC, GNMA or FHLB, while we retain the right to service these loans. Loans originated under the guidelines of the Federal Housing Administration or FHA, US Department of Veterans Affairs or VA, and United States Department of Agriculture or USDA are generally sold servicing released to a correspondent bank or mortgage company. We have the option to sell loans on a servicing-released or servicing-retained basis to securitizers and correspondent lenders. A small percentage of our loans are brokered to other lenders. On occasion, we may sell a portion of our MSR portfolio. We manage the loan funding and the interest rate risk associated with the secondary market loan sales and the retained one-to-four-family mortgage servicing rights within this business segment. One-to-four-family loans originated for investment are allocated to the home lending segment with a corresponding provision expense and FTP for cost of funds. Segment Financial Results The tables below summarize the financial results for each segment based primarily on the number of FTEs and assets within each segment for the three months ended March 31, 2017 and 2016: At or For the Three Months Ended March 31, 2017 Home Lending Commercial and Consumer Banking Total Condensed income statement: Net interest income (1) $ 630 $ 8,345 $ 8,975 Provision for loan losses (80 ) 80 — Noninterest income 4,387 1,033 5,420 Noninterest expense (4,017 ) (6,360 ) (10,377 ) Income before provision for income taxes 920 3,098 4,018 Provision for income taxes (326 ) (1,099 ) (1,425 ) Net income $ 594 $ 1,999 $ 2,593 Total average assets at quarter end $ 171,424 $ 667,327 $ 838,751 FTEs 113 198 311 At or For the Three Months Ended March 31, 2016 Home Lending Commercial and Consumer Banking Total Condensed income statement: Net interest income (1) $ 528 $ 7,295 $ 7,823 Provision for loan losses (25 ) (575 ) (600 ) Noninterest income 3,401 920 4,321 Noninterest expense (3,013 ) (5,909 ) (8,922 ) Income before provision for income taxes 891 1,731 2,622 Provision for income taxes (327 ) (634 ) (961 ) Net income $ 564 $ 1,097 $ 1,661 Total average assets at quarter end $ 152,522 $ 627,513 $ 780,035 FTEs 96 179 275 (1) Net interest income is the difference between interest earned on assets and the cost of liabilities to fund those assets. Interest earned includes actual interest earned on segment assets and, if the segment has excess liabilities, interest credits for providing funding to the other segment. The cost of liabilities includes interest expense on segment liabilities and, if the segment does not have enough liabilities to fund its assets, a funding charge based on the cost of excess liabilities for another segment.

Accounting Policies [Abstract]
Financial Statement Presentation	Financial Statement Presentation - The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (“SEC”). It is recommended that these unaudited interim consolidated financial statements be read in conjunction with the Company’s Annual Report on Form 10-K with all of the audited information and footnotes required by U.S. GAAP for complete financial statements for the year ended December 31, 2016, as filed with the SEC on March 16, 2017. In the opinion of management, all normal adjustments and recurring accruals considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. The results for the three months ended March 31, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017, or any other future period. The preparation of financial statements, in conformity with U.S. GAAP, requires management to make estimates and assumptions that affect amounts reported in the financial statements. Actual results could differ from these 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, and the valuation of servicing rights. 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 in dollars to the nearest thousands. Certain prior year amounts have been reclassified to conform to the 2017 presentation with no change to consolidated net income or stockholders’ equity previously reported.
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.
Segment Reporting, Policy [Policy Text Block]	Segment Reporting - The Company operates as two segments organized by two lines of business: commercial and consumer banking segment and home lending segment. The Company’s business segments are determined based on the products and services provided, as well as the nature of the related business activities, and they reflect the manner in which financial information is regularly reviewed for the purpose of allocating resources and evaluating performance of the Company’s businesses. The results for these business segments are based on management’s accounting process, which assigns income statement items and assets to each responsible operating segment. This process is dynamic and is based on management’s view of the Company’s operations. See Note 15 - Business Segments.
Subsequent Events, Policy [Policy Text Block]	Subsequent Events - The Company has evaluated events and transactions subsequent to March 31, 2017, for potential recognition or disclosure.
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which creates Topic 606 and supersedes Topic 605, Revenue Recognition. In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606) , which postponed the effective date of 2014-09. In March 2016, the FASB issued ASU 2016-08, R evenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) , which amended the principal versus agent implementation guidance set for in ASU 2014-09. Among other things, ASU 2016-08 clarifies that an entity should evaluate whether it is the principal or the agent for each specified good or service promised in a contract with a customer. In April 2016, the FASB issued ASU No. 2016-10, R evenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing . The ASU amends certain aspects of the guidance set forth in the FASB's new revenue standard related to identifying performance obligations and licensing implementation. The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In general, the new guidance requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which provides clarifying guidance in certain narrow areas and adds some practical expedients, but does not change the core revenue recognition principle in Topic 606. The ASU is effective for public entities for interim and annual periods beginning after December 15, 2017; early adoption is not permitted. For financial reporting purposes, the ASU allows for either full retrospective adoption, meaning the ASU is applied to all of the periods presented, or modified retrospective adoption, meaning the ASU is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. As a bank holding company, key revenue sources, such as interest income have been identified as out of the scope of this new guidance. The Company’s preliminary analysis suggests that the adoption of this accounting standard is not expected to have a material impact on the Company’s consolidated financial statements as substantially all of the Company’s other revenues are also excluded from the scope of the new guidance. New accounting guidance related to the adoption of this standard continues to be released by the FASB, which could impact the Company’s preliminary analysis of materiality and may change the preliminary conclusions reached as to the application of this new guidance. 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. Once adopted, we expect to report higher assets and liabilities as a result of including right-of-use assets and lease liabilities related to certain banking offices and certain equipment under noncancelable operating lease agreements, however, based on current leases, the adoption of ASU 2016-02 is expected to increase our Consolidated Balance Sheets by less than 5% and not to have a material impact on our regulatory capital ratios. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. Organizations will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. The ASU requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early application will be permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating the impact of this ASU on the Company’s consolidated financial statements. Once adopted, we expect our allowance for loan losses to increase, however, until our evaluation is complete the magnitude of the increase will be unknown. In January 2017, the FASB issued ASU 2017-04 - Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The ASU was issued to simplify the subsequent measurement of goodwill and the amendment eliminates Step 2 from the goodwill impairment test. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU is effective for annual reporting periods beginning after December 31, 2019. Early adoption of the ASU is permitted. The Company does not expect this ASU to have a material impact on the Company's consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities . The ASU shortens the amortization period for certain callable debt securities held at a premium. The standard will take effect for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of ASU No. 2017-08 is not expected to have a material impact on the Company's consolidated financial statements.
Loan Portfolio Segment	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. 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. Home Equity Lending . Loans originated by the Company secured by second mortgages on one-to-four-family residences, including home equity lines of credit in our market areas. One-to-Four-Family Real Estate Lending . One-to-four-family residential loans include owner occupied properties (including second homes), and non-owner occupied properties. These loans originated by the Company are secured by first mortgages on one-to-four-family residences in our market areas that the Company intends to hold (excludes loans held for sale). 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. Marine . Loans originated by the Company secured by boats to borrowers primarily located in its market areas. Other Consumer. Loans originated by the Company, including automobiles, recreational vehicles, direct home improvement loans, loans on deposits, and other consumer loans, primarily consisting of personal lines of credit. Commercial Business Loans Commercial and Industrial Lending . Loans originated by the Company to local small and mid-sized businesses in our Puget Sound market area are secured primarily by accounts receivable, inventory, or personal property, plant and equipment. Commercial and industrial loans are made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. Warehouse Lending . Loans originated by the Company’s mortgage and construction warehouse lending program through which the Company funds third-party lenders originating residential mortgage and construction loans for sale into the secondary market and speculative construction loans for residential properties built for sale to single family households. These loans are secured by the notes and assigned deeds of trust associated with the residential mortgage and construction loans on properties primarily located in the Company’s market areas.
Nonaccrual and Past Due Loans	Nonaccrual and Past Due Loans . Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are automatically placed on nonaccrual once the loan is 90 days past due or sooner if, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, or as required by regulatory authorities.
Credit Quality Indicators	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, solar, marine, 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 rated “4” or “5” internally. Loans that are past due more than 90 days are classified “Substandard” and risk rated “8” internally until the loan has demonstrated consistent performance, typically six months of contractual payments. 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.
Troubled Debt Restructured Loans	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.
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 for reporting purposes under U.S. GAAP. 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.
Loan Commitments	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.
Determination of Fair Market Values	Determination of Fair Market Values: Securities Available-for-Sale - The fair value of securities available-for-sale are recorded 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. TBA mortgage-backed securities are fair valued on similar contracts in active markets (Level 2) while locks and forwards with customers and investors are fair valued using similar contracts in the market and changes in the market interest rates (Levels 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. Management will utilize discounted cash flow impairment for TDRs when the change in terms results in a discount to the overall cash flows to be received (Level 3).
Employee Stock Ownership Plan	Employees of the Company and the Bank who have been credited with at least 1,000 hours of service during a 12 -month period are eligible to participate in the ESOP.
