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 (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 consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and with prevailing practices within the banking and securities industries. In preparing such financial statements, management is required to make certain estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the balance sheet and the reported amounts of revenues and expenses for the reporting period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan and lease losses, fair value of financial instruments, the valuation of servicing rights, and the deferred income taxes . Amounts presented in the consolidated financial statements and footnote tables are rounded and presented in thousands of dollars except per share amounts. In the narrative footnote discussion, amounts are rounded and presented in millions of dollars to one decimal point if the amounts are above $ 1.0 million . Amounts below $ 1.0 million are rounded and presented in dollars to the nearest thousands. Certain prior year amounts have been reclassified to conform to the 2016 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’s major lines of business are community banking. Management has determined that the Company operates as a single operating segment based on U.S. GAAP. Subsequent Events - The Company has evaluated events and transactions subsequent to December 31, 2016, for potential recognition or disclosure. Cash and Cash Equivalents - Cash and cash equivalents include cash and due from banks, and interest-bearing balances due from other banks and the Federal Reserve Bank of San Francisco (“FRB”) and have a maturity of 90 days or less at the time of purchase. The Company had $ 7.8 million of cash and due from banks and interest-bearing deposits at other financial institutions in excess of Federal Deposit Insurance Corporation (“FDIC”) insured limits at December 31, 2016, and none at December 31, 2015. Because the Company places these deposits with major financial institutions and monitors the financial condition of these institutions, management believes the risk of loss to any deposits in excess of FDIC limits to be minimal. Securities Available-for-Sale - Securities available-for-sale consist of debt securities that the Company has the intent and ability to hold for an indefinite period, but not necessarily to maturity. Such securities may be sold to implement the Company’s asset/liability management strategies and in response to changes in interest rates and similar factors. Securities available-for-sale are reported at fair value. Realized gains and losses on securities available-for-sale, determined using the specific identification method, are included in results of operations. Amortization of premium and accretion of discounts are recognized in interest income over the period to maturity. Unrealized holding gains and losses, net of the related deferred tax effect, are reported as a net amount in a separate component of equity entitled accumulated other comprehensive income. Unrealized losses that are deemed to be other than temporary are reflected in results of operations. Any declines in the values of these securities that are considered to be other-than-temporary-impairment (“OTTI”) and credit-related are recognized in earnings. Noncredit-related OTTI on securities not expected to be sold is recognized in other comprehensive income. The review for OTTI is conducted on an ongoing basis and takes into account the severity and duration of the impairment, recent events specific to the issuer or industry, fair value in relationship to cost, extent and nature of change in fair value, creditworthiness of the issuer including external credit ratings and recent downgrades, trends and volatility of earnings, current analysts’ evaluations, and other key measures. In addition, the Company does not intend to sell the securities and it is more likely than not that we will not be required to sell the securities before recovery of their amortized cost basis. In doing this, we take into account our balance sheet management strategy and consideration of current and future market conditions. Dividends and interest income are recognized when earned. Federal Home Loan Bank Stock - The Bank’s investment in FHLB stock is carried at cost, which approximates fair value. As a member of the FHLB system, the Bank is required to maintain an investment in capital stock of the FHLB in an amount of $ 813,000 and 4.0% of advances from the FHLB. The Bank’s required minimum level of investment in FHLB stock is based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. At December 31, 2016 and 2015, the Bank’s minimum level of investment requirement in FHLB stock was $ 2.7 million and $ 4.6 million, respectively. The Bank was in compliance with the FHLB minimum investment requirement at December 31, 2016 and 2015. Management evaluates FHLB stock for impairment as needed. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared with the capital stock amount for the FHLB and the length of time this situation has persisted; (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB; and (4) the liquidity position of the FHLB. Based on its evaluation, management determined that there was no impairment of FHLB stock at December 31, 2016 and 2015, respectively. Loans Held for Sale - The Bank records all mortgage loans held-for-sale at fair value. Fair value is determined by outstanding commitments from investors or current investor yield requirements calculated on the aggregate loan basis. Origination fees and costs are recognized in earnings at the time of origination. Mortgage loans held-for-sale are sold with the mortgage service rights either released or retained by the Bank. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loans sold. All sales are made with limited recourse against the Company. Derivatives - Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free-standing derivatives. The fair value of the interest rate lock is recorded at the time the commitment to fund the mortgage loan is executed and is adjusted for the expected exercise of the commitments to fund the loans, the Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest on the loan is locked. Changes in the fair values of these derivatives are reported in “Gain on sale of loans” on the Consolidated Statements of Income. Loans Receivable - Loans receivable, are stated at the amount of unpaid principal reduced by an allowance for loan losses and net deferred fees or costs. Interest on loans is calculated using the simple interest method based on the daily balance of the principal amount outstanding and is credited to income as earned. Loan fees, net of direct origination costs, are deferred and amortized over the life of the loan using the effective yield method. Interest on loans is accrued daily based on the principal amount outstanding. Generally, the accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due or when they are past due 90 days as to either principal or interest (based on contractual terms), unless they are well secured and in the process of collection. All interest accrued but not collected for loans that are placed on non-accrual status or charged off are reversed against interest income. Subsequent collections on a cash basis are applied proportionately to past due principal and interest, unless collectability of principal is in doubt, in which case all payments are applied to principal. Loans are returned to accrual status when the loan is deemed current, and the collectability of principal and interest is no longer doubtful, or, generally, when the loan is less than 90 days delinquent, and performing according to its contractual terms after a period of six months performance. The Company charges fees for originating loans. These fees, net of certain loan origination costs, are deferred and amortized to income, on the level-yield basis, over the loan term. If the loan is repaid prior to maturity, the remaining unamortized net deferred loan origination fee is recognized in income at the time of repayment. Impaired Loans - A loan is considered impaired when it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the original or modified terms of the loan agreement. Impaired loans are measured on a loan by loan basis based on the estimated fair value of the collateral less estimated cost to sell if the loan is considered collateral dependent. Impaired loans not considered to be collateral dependent are measured based on the present value of expected future cash flows. Impairment is measured for each loan in the portfolio except for the smaller groups of homogeneous consumer loans. The categories of non-accrual loans and impaired loans overlap, although they are not coextensive. The Company considers all circumstances regarding the loan and borrower on an individual basis when determining whether an impaired loan should be placed on non-accrual status, such as the financial strength of the borrower, the collateral value, reasons for delay, payment record, the amount of past due and the number of days past due. Loans that experience insignificant payment delays and payment shortfalls are generally not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of shortfall in relation to the principal and interest owed. Troubled Debt Restructured Loans - Troubled debt restructured (“TDR”) loans are loans for which the Company, for economic or legal reasons related to the borrower’s financial condition, has granted a significant concession to the borrower that it would otherwise not consider. 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 and 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. Allowance for Loan Losses - The allowance for loan losses is maintained at a level considered adequate to provide for probable losses on existing loans based on evaluating known and inherent risks in the loan portfolio. The allowance is reduced by loans charged-off and increased by provisions charged to earnings and recoveries on loans previously charged-off. The allowance is based on management’s periodic, systematic evaluation of factors underlying the quality of the loan portfolio including changes in the size and composition of the loan portfolio, the estimated value of any underlying collateral, actual loan loss experience, current economic conditions, and detailed analysis of individual loans for which full collectability may not be assured. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. While management uses the best information available to make its estimates, future adjustments to the allowance may be necessary if there is a significant change in economic and other conditions. The appropriateness of the allowance for loan losses is estimated based on these factors and trends identified by management at the time the financial statements are prepared. When available information confirms that specific loans or portions thereof are uncollectible, these amounts are charged-off against the allowance for loan losses. The existence of some or all of the following criteria will generally confirm that a loss has been incurred: the loan is significantly delinquent and the borrower has not evidenced the ability or intent to bring the loan current; the Company has no recourse to the borrower, or if it does, the borrower has insufficient assets to pay the debt; the estimated fair value of the loan collateral is significantly below the current loan balance, and there is little or no near-term prospect for improvement. A provision of loan losses is charged against income and added to the allowance for loan losses based on regular assessment of the loan portfolio. The allowance for loan losses is allocated to certain loan categories based on the relative risk characteristics, asset classifications, and actual loss experience within the loan portfolio. Although management has allocated the allowance for loan losses to various loan portfolio segments, the allowance is general in nature and is available for the loan portfolio in its entirety. The ultimate recovery of all loans is susceptible to future market factors beyond the Company’s control. These factors may result in losses or recoveries differing significantly from those provided for in the financial statements. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations. Reserve for Unfunded Loan Commitments - The reserve for unfunded loan commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to these unfunded credit facilities. The determination of the adequacy of the reserve is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. The reserve for unfunded loan commitments is included in other liabilities on the consolidated balance sheet, with changes to the balance charged against noninterest expense. Premises and Equipment, Net - Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The estimated useful lives used to compute depreciation include building and building improvements from 25 to 40 years and furniture, fixtures, and equipment from 3 to 10 years. Leasehold and tenant improvements are amortized using the straight-line method over the lesser of useful life or the life of the related lease. Gains or losses on dispositions are reflected in results of operations. Management reviews buildings, improvements and equipment for impairment on an annual basis or whenever events or changes in the circumstances indicate that the undiscounted cash flows for the property are less than its carrying value. If identified, an impairment loss is recognized through a charge to earnings based on the fair value of the property. Transfers of Financial Assets - Transfers of an entire financial asset, a group of entire financial assets, or participating interest in an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Servicing Rights - Servicing assets are recognized as separate assets when rights are acquired through purchase or through sale of financial assets. Generally, purchased servicing rights are capitalized at the cost to acquire the rights. For sales of mortgage, commercial and consumer loans, a portion of the cost of originating the loan is allocated to the servicing right based on relative fair value. Fair value is based on market prices for comparable mortgage, commercial, or consumer servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds, and default rates and losses. Servicing assets are evaluated quarterly for impairment based upon the fair value of the rights as compared to amortized cost. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type, and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranches. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income. Capitalized servicing rights are stated separately on the consolidated balance sheets and are amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Income Taxes - The Company files a consolidated federal income tax return. Deferred federal income taxes result from temporary differences between the tax basis of assets and liabilities, and their reported amounts in the financial statements. These will result in differences between income for tax purposes and income for financial reporting purposes in future years. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established to reduce the net recorded amount of deferred tax assets if it is determined to be more likely than not, that all or some portion of the potential deferred tax asset will not be realized. The Financial Accounting Standards Board (“FASB”) issued guidance related to accounting for uncertainty in income taxes. The guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It is the Company’s policy to record any penalties or interest arising from federal or state taxes as a component of income tax expense. Employee Stock Ownership Plan ( “ ESOP ” ) - Compensation expense recognized for the Company’s ESOP equals the fair value of shares that have been allocated or committed to be released for allocation to participants. Any difference between the fair value of the shares at the time and the ESOP’s original acquisition cost is charged or credited to stockholders’ equity (additional paid-in capital). The cost of ESOP shares that have not yet been allocated or committed to be released is deducted from stockholders’ equity. Earnings Per Share - Basic earnings per share (“EPS”) are computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. For purposes of computing basic and dilutive EPS, ESOP shares that have been committed to be released are outstanding and ESOP shares that have not been committed to be released shall not be considered outstanding. Comprehensive Income (Loss) - Comprehensive income (loss) is comprised of net income and other comprehensive income (loss). Other comprehensive income (loss) includes items recorded directly to equity, such as unrealized holding gains and losses on securities available-for-sale. Financial Instruments - In the ordinary course of business, the Company has entered into agreements for off-balance-sheet financial instruments consisting of commitments to extend credit and stand-by letters of credit. Such financial instruments are recorded in the financial statements when they are funded or related fees are incurred or received. Restricted Assets - Federal Reserve regulations require that the Bank maintain reserves in the form of cash on hand and deposit balances with the FRB, based on a percentage of deposits. The amounts of such balances for the years ended December 31, 2016 and 2015 were $ 10.7 million and $ 3.0 million , respectively, included in interest-bearing deposits at other financial institutions on the balance sheet. Marketing and Advertising Costs - The Company records marketing and advertising costs as expenses as they are incurred. Total marketing and advertising expense was $ 710,000 and $ 709,000 for the years ended December 31, 2016 and 2015, respectively. Stock-Based Compensation - Compensation cost is recognized for stock options and restricted stock awards, based on the fair value of these awards at the grant date. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the grant date is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. Goodwill - Goodwill is recorded upon completion of a business combination as the difference between the purchase price and the fair value of net identifiable assets acquired. Goodwill was not recorded until the first quarter of 2016 in recognition of the four retail branches purchased from Bank of America. Subsequent to initial recognition, the Company tests goodwill for impairment during the fourth quarter of each fiscal year, or more often if events or circumstances, such as adverse changes in the business climate indicate there may be impairment. There was no goodwill impairment at December 31, 2016 and there was no goodwill at December 31, 2015. Application of New Accounting Guidance At October 1, 2016, the Company adopted FASB Accounting Standards Update (“ASU”) No 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . ASU 2016-09, seeks to simplify several aspects of the accounting for employee share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. As required by ASU 2016-09, all adjustments are reflected as of the beginning of the fiscal year, January 1, 2016. By applying this ASU, the Company no longer adjusts common stock for the tax impact of shares released, instead the tax impact is recognized as tax expense in the period the shares are released. This simplifies the tracking of the excess tax benefits and deficiencies, but could cause volatility in tax expense for the periods presented. The statement of cash flows has been adjusted to reflect the provisions of this ASU. The application of this ASU did not have a material impact on the consolidated financial statements. RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the FASB issued 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 revenues are 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 20

Business Combinations [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, National Association (“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 for the bank branches and parking facilities and certain other assets of the branches effective January 22, 2016. As of December 31, 2016, approximately $ 162.2 million of the acquired deposits remain at 1st Security Bank. These banks attracted new deposits with an aggregated total of $ 195.5 million, including public funds at year ended December 31, 2016. 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 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 $ 522,000 for the year ended December 31, 2016, and none for the same period in 2015. Amortization expense for core deposit intangible is expected to be as follows: 2017 $ 400 2018 307 2019 235 2020 181 2021 166 Thereafter 428 Total $ 1,717

Investment securities that were in an unrealized loss position at December 31, 2016 and 2015 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 17 investments with unrealized losses of less than one year and eight investments with unrealized losses of more than one year at December 31, 2015. The unrealized losses associated with these investments are believed to be caused by changing market conditions that are considered to be temporary and the Company does not intend to sell these securities, and it is not likely to be required to sell these securities prior to maturity. No other-than-temporary impairment was recorded for the years ended December 31, 2016 and 2015. The contractual maturities of securities available-for-sale at December 31, 2016 and 2015 are listed below. Expected maturities of mortgage-backed securities may differ from contractual maturities because borrowers may have the right to call or prepay the obligations; therefore, these securities are classified separately with no specific maturity date.

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

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 graded “ 4 ” or “5”internally. Loans that are past due more than 90 days are classified “Substandard” risk graded “ 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.

Transfers and Servicing [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 $ 977.1 million and $ 636.1 million at December 31, 2016 and 2015, respectively and are carried at the lower of cost or market. The following table summarizes servicing rights activity for the years ended December 31, 2016 and 2015: 2016 2015 Beginning balance $ 5,811 $ 3,061 Additions 4,194 3,699 Servicing rights amortized (1,549 ) (949 ) Recovery on servicing rights 3 — Ending balance $ 8,459 $ 5,811 The fair market value of the servicing rights’ assets was $ 11.7 million and $ 6.8 million at December 31, 2016 and December 31, 2015, 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 December 31, Key assumptions: 2016 2015 Weighted average discount rate 9.5 % 8.5 % Conditional prepayment rate (“CPR”) 8.8 % 12.2 % Weighted average life in years 7.9 6.4 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 December 31, 2016 and December 31, 2015 were as follows: December 31, 2016 December 31, 2015 Aggregate portfolio principal balance $ 973,139 $ 631,812 Weighted average rate of note 3.9 % 4.0 % At December 31, 2016 Base 0.5% Adverse Change 1.0% Adverse 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 % At December 31, 2015 Base 0.5% Adverse Change 1.0% Adverse Change Conditional prepayment rate 12.2 % 17.8 % 25.3 % Fair value MSR $ 6,813 $ 5,660 $ 4,557 Percentage of MSR 1.1 % 0.9 % 0.7 % Discount rate 8.5 % 9.0 % 9.5 % Fair value MSR $ 6,813 $ 6,678 $ 6,548 Percentage of MSR 1.1 % 1.1 % 1.0 % The above tables show the sensitivity to market rate changes for the par rate coupon for a conventional one-to-four-family FNMA/FHLMC/GNMA/FHLB serviced home loan. The above tables reference a 50 basis point and 100 basis point decrease in note rate. These sensitivities are hypothetical and should be used with caution as the tables above demonstrate the Company’s methodology for estimating the fair value of MSR is highly sensitive to changes in key assumptions. For example, actual prepayment experience may differ and any difference may have a material effect on MSR fair value. Changes in fair value resulting from changes in assumptions generally cannot be extrapolated because the relationship of the change in the assumption to the change in fair value may not be linear. Also, in these tables, the effects of a variation in a particular assumption on the fair value of the MSR is calculated without changing any other assumption; in reality, changes in one factor may be associated with changes in another (for example, decreases in market interest rates may provide an incentive to refinance; however, this may also indicate a slowing economy and an increase in the unemployment rate, which reduces the number of borrowers who qualify for refinancing), which may magnify or counteract the sensitivities. Thus, any measurement of MSR fair value is limited by the conditions existing and assumptions made as a particular point in time. Those assumptions may not be appropriate if they are applied to a different point in time. The Company recorded $ 2.0 million and $ 1.3 million of contractually specified servicing fees, late fees, and other ancillary fees resulting from servicing of mortgage, commercial and consumer loans for the years ended December 31, 2016 and 2015, respectively. The income, net of amortization, is reported in noninterest income.

Debt Disclosure [Abstract]
Debt	DEBT Borrowings The Bank is a member of the FHLB of Des Moines, which entitles it to certain benefits including a variety of borrowing options consisting of a secured credit line that allows both fixed and variable rate advances. The FHLB borrowings at December 31, 2016 and 2015, consisted of a warehouse securities credit line (“securities line”), which allows advances with interest rates fixed at the time of borrowing and a warehouse Federal Funds (“Fed Funds”) advance, which allows daily advances at variable interest rates. Credit capacity is primarily determined by the value of assets collateralized at the FHLB, funds on deposit at the FHLB, and stock owned by the Bank. Credit is limited to 35% of the Company’s total assets. The Bank entered into an Advanced, Pledges and Security Agreement with the FHLB for which specific loans are pledged to secure these credit lines. At December 31, 2016, loans of approximately $249.8 million were pledged to the FHLB with a borrowing capacity, net of advances of $177.5 million . In addition, all FHLB stock owned by the Company is collateral for credit lines. The Bank maintains a short-term borrowing line with the FRB with total credit based on eligible collateral. The Bank can borrow under the Term Auction or Term Facility at rates published by the San Francisco FRB. At December 31, 2016 and 2015, the Bank had approximately $170.1 million in pledged consumer loans with a Term Auction or Term Facility borrowing capacity of $85.9 million and $ 79.5 million , respectively, of which none was outstanding at either date. The Bank also had $40.0 million unsecured Fed Funds lines of credit with other large financial institutions of which none was outstanding at December 31, 2016. Advances on these lines at December 31, 2016 and 2015 were as follows: 2016 2015 Federal Home Loan Bank - (interest rates ranging from 0.86% to 1.73% and 0.34% to 1.73% at December 31, 2016 and 2015, respectively) $ 12,670 $ 98,769 Total $ 12,670 $ 98,769 Subordinated Note On October 15, 2015 (the “Closing Date”), FS Bancorp, Inc. issued an unsecured subordinated term note in the aggregate principal amount of $10.0 million due October 1, 2025 (the “Subordinated Note”) pursuant to a Subordinated Loan Agreement with Community Funding CLO, Ltd. The Subordinated Note bears interest at an annual interest rate of 6.50% , payable by the Company quarterly in arrears on January 1, April 1, July 1 and October 1 of each year, commencing on the first such date following the Closing Date and on the maturity date. The Subordinated Note will mature on October 1, 2025 but may be prepaid at the Company’s option and with regulatory approval at any time on or after five years after the Closing Date or at any time upon certain events, such as a change in the regulatory capital treatment of the Subordinated Note or the interest on the Subordinated Note no longer being deductible by the Company for United States federal income tax purposes. The Company contributed $9.0 million of the proceeds from the Subordinated Note as additional capital to the Bank in the fourth quarter of 2015 and used the balance to fund general working capital and operating expenses.

Employee Benefits	EMPLOYEE BENEFITS Employee Stock Ownership Plan On January 1, 2012, the Company established an ESOP for eligible employees of the Company and the Bank. Employees of the Company and the Bank who have been credited with at least 1000 hours of service during a 12 -month period are eligible to participate in the ESOP. The ESOP borrowed $ 2.6 million from FS Bancorp, Inc. and used those funds to acquire 259,210 shares of FS Bancorp, Inc. common stock in the open market at an average price of $ 10.17 per share during the second half of 2012. It is anticipated that the Bank will make contributions to the ESOP in amounts necessary to amortize the ESOP loan payable to FS Bancorp, Inc. over a period of 10 years , bearing interest at 2.30% . Intercompany expenses associated with the ESOP are eliminated in consolidation. Shares purchased by the ESOP with the loan proceeds are held in a suspense account and allocated to ESOP participants on a pro rata basis as principal and interest payments are made by the ESOP to FS Bancorp, Inc. The loan is secured by shares purchased with the loan proceeds and will be repaid by the ESOP with funds from the Bank’s discretionary contributions to the ESOP and earnings on the ESOP assets. Payments of principal and interest are due annually on December 31, the Company’s fiscal year end. On December 31, 2016, the ESOP made the fifth annual installment payment 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 December 31, 2016 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 years ended December 31, 2016 and 2015, was $ 832,000 and $ 652,000 , respectively. Shares held by the ESOP at December 31, 2016 and December 31, 2015, were as follows (shown as actual): December 31, 2016 2015 Allocated shares 126,589 102,359 Committed to be released shares — — Unallocated shares 129,605 155,526 Total ESOP shares 256,194 257,885 Fair value of unallocated shares (in thousands) $ 4,158 $ 3,913 401(k) Plan The Company has a salary deferral 401(k) Plan covering substantially all of its employees. Employees are eligible to participate in the 401(k) plan at the date of hire if they are 18 years of age. Eligible employees may contribute through payroll deductions and are 100% vested at all times in their deferral contributions account. The Company matches 100% for contributions between 1% and 3% , and 50% for contributions between 4% and 5% . There was a $759,000 and $589,000 matching contribution for the years ended December 31, 2016 and 2015, respectively.

Commitments and Contingencies

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 December 31, 2016 and 2015: COMMITMENTS TO EXTEND CREDIT 2016 2015 REAL ESTATE LOANS Commercial $ 108 $ 1,988 Construction and development 57,016 44,109 One-to-four-family (includes held for sale) 79,870 76,013 Home equity 26,129 18,089 Multi-family 426 429 Total real estate loans 163,549 140,628 CONSUMER LOANS 8,527 5,754 COMMERCIAL BUSINESS LOANS Commercial and industrial 31,775 39,537 Warehouse lending 51,102 27,601 Total commercial business loans 82,877 67,138 Total commitments to extend credit $ 254,953 $ 213,520 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the amount of the total commitments do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate, and income-producing commercial properties. Unfunded commitments under commercial lines of credit, revolving credit lines and overdraft protection agreements are commitments for possible future extensions of credit to existing customers. These lines of credit are uncollateralized and usually do not contain a specified maturity date and ultimately may not be drawn upon to the total extent to which the Company is committed. The Company has established reserves for estimated losses from unfunded commitments of $ 179,000 and $ 147,000 at December 31, 2016 and 2015, respectively. One-to-four-family commitments included in the table above are accounted for as fair value derivatives and do not carry an associated loss reserve. The Company has entered into a severance agreement with its Chief Executive Officer. The severance agreement, subject to certain requirements, generally includes a lump sum payment to the Chief Executive Officer equal to 24 months of base compensation in the event their employment is involuntarily terminated, other than for cause or the executive terminates his employment with good reason, as defined in the severance agreement. The Company has entered into change of control agreements with its Chief Financial Officer, 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. Because of the nature of our activities, the Company is subject to various pending and threatened legal actions, which arise in the ordinary course of business. From time to time, subordination liens may create litigation which requires us to defend our lien rights. In the opinion of management, liabilities arising from these claims, if any, will not have a material effect on our financial position. The Company had no material pending legal actions at 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 $955,000 and $561,000 to cover loss exposure related to these guarantees for one-to-four-family loans sold into the secondary market at December 31, 2016 and 2015, respectively, which is included in other liabilities in the Consolidated Balance Sheets.

Significant Concentration of Credit Risk	SIGNIFICANT CONCENTRATION OF CREDIT RISK Most of the Company’s business and lending activities are primarily with customers located in the greater Puget Sound area and one loan production office located in the Tri-Cities, Washington. The Company originates real estate and consumer loans and has concentrations in these areas, however, indirect home improvement loans are originated through a network of home improvement contractors and dealers located throughout Washington, Oregon, Idaho, and California. The Company also originates solar loans through contractors and dealers in the state of California. Generally, loans are secured by deposit accounts, personal property, or real estate. Rights to collateral vary and are legally documented to the extent practicable. Local economic conditions may affect borrowers’ ability to meet the stated repayment terms.

Regulatory Capital

Regulatory Capital Requirements [Abstract]
Regulatory Capital	REGULATORY CAPITAL 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 December 31, 2016 and December 31, 2015, 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, as of December 31, 2016, that the Company meets all capital adequacy requirements to which it is subject. The following tables compare the Bank’s actual capital amounts and ratios at December 31, 2016 and 2015 to their minimum regulatory capital requirements and well capitalized regulatory capital at those dates (dollars in thousands): To be Well Capitalized Under Prompt Corrective Action Provisions For Capital Adequacy Purposes Actual Bank Only Amount Ratio Amount Ratio Amount Ratio At December 31, 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 % At December 31, 2015 Total risk-based capital (to risk-weighted assets) $ 85,570 15.51 % $ 44,132 8.00 % $ 55,164 10.00 % Tier 1 risk-based capital (to risk-weighted assets) $ 78,662 14.26 % $ 33,099 6.00 % $ 44,132 8.00 % Tier 1 leverage capital (to average assets) $ 78,662 12.14 % $ 25,924 4.00 % $ 32,406 5.00 % CET 1 capital (to risk-weighted assets) $ 78,662 14.26 % $ 24,824 4.50 % $ 35,857 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 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 December 31, 2016, the Company would have exceeded all regulatory capital requirements. The regulatory capital ratios calculated for FS Bancorp Inc. at December 31, 2016 were 9.5% 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.

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 to be announced (“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 using 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 (Level 2 and 3). Impaired Loans - Fair value adjustments to impaired collateral dependent loans are recorded to reflect partial write-downs based on the current appraised value of the collateral or internally developed models, which contain management’s assumptions. Management will utilize discounted cashflow impairment for TDRs when the change in terms result in a discount to the overall cashflows to be received (Level 3). The following tables present securities available-for-sale measured at fair value on a recurring basis at December 31, 2016 and December 31, 2015: 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 Securities Available-for-Sale At December 31, 2015 Level 1 Level 2 Level 3 Total U.S. agency securities $ — $ 6,035 $ — $ 6,035 Corporate securities — 3,433 — 3,433 Municipal bonds — 18,891 — 18,891 Mortgage-backed securities — 22,835 — 22,835 U.S. Small Business Administration securities — 4,023 — 4,023 Total $ — $ 55,217 $ — $ 55,217 The following table presents mortgage loans held for sale measured at fair value on a recurring basis at December 31, 2016 and December 31, 2015: Mortgage Loans Held for Sale Level 1 Level 2 Level 3 Total December 31, 2016 $ — $ 52,553 $ — $ 52,553 December 31, 2015 $ — $ 44,925 $ — $ 44,925 The following tables present the fair value of interest rate lock commitments with customers, individual forward sale commitments with investors and paired off commitments with investors measured at their fair value on a recurring basis at December 31, 2016 and December 31, 2015: Interest Rate Lock Commitments with Customers Level 1 Level 2 Level 3 Total December 31, 2016 $ — $ — $ 818 $ 818 December 31, 2015 $ — $ — $ 698 $ 698 Individual Forward Sale Commitments with Investors Level 1 Level 2 Level 3 Total December 31, 2016 $ — $ 495 $ 177 $ 672 December 31, 2015 $ — $ 3 $ 74 $ 77 Paired Off Commitments with Investors Level 1 Level 2 Level 3 Total December 31, 2016 $ — $ 747 $ — $ 747 December 31, 2015 $ — $ 30 $ — $ 30 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). 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 in the fourth quarter of 2016 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).

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 year. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. The following table presents a reconciliation of the components used to compute basic and diluted earnings per share for the years ended December 31, 2016 and 2015. At or For the Years Ended December 31, Numerator: 2016 2015 Net Income (in thousands) $ 10,499 $ 8,876 Denominator: Basic weighted average common shares outstanding 2,896,209 2,978,165 Dilutive shares 93,950 54,352 Diluted weighted average common shares outstanding 2,990,159 3,032,517 Basic earnings per share $ 3.63 $ 2.98 Diluted earnings per share $ 3.51 $ 2.93 The Company purchased 259,210 shares in the open market during the year ended December 31, 2012, for the ESOP. For earnings per share calculations, the ESOP shares committed to be released are included as outstanding shares for both basic and diluted earnings per share. There were 129,605 shares in the ESOP that were not committed to be released at December 31, 2016.

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 TBA mortgage-backed securities. These commitments and contracts are considered derivatives but have not been designated as hedging instruments. Rather, they are accounted for as free-standing derivatives, or economic hedges, with changes in the fair value of the derivatives reported in noninterest income. The Company recognizes all derivative instruments as either other assets or other liabilities on the Consolidated Balance Sheets and measures those instruments at fair value. The following tables summarize the Company’s derivative instruments at the dates indicated: 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 — December 31, 2015 Fair Value Notional Asset Liability Fallout adjusted interest rate lock commitments with customers $ 34,154 $ 698 $ — Mandatory and best effort forward commitments with investors 24,135 74 — Forward TBA mortgage-backed securities 49,000 3 — TBA mortgage-backed securities forward sales paired off with investors 28,500 30 — 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 gain of $ 3.1 million and $ 1.9 million for the years ended December 31, 2016 and 2015, respectively.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION Stock Options and Restricted Stock In September 2013, the shareholders of FS Bancorp, Inc. approved the FS Bancorp, Inc. 2013 Equity Incentive Plan (“Plan”). The Plan provides for the grant of stock options and restricted stock awards. Total share-based compensation expense for the Plan was $ 783,000 for the year ended December 31, 2016, and $746,000 for the year ended December 31, 2015. The related income tax benefit was $ 274,000 for the year ended December 31, 2016, and $265,000 for 2015. Stock Options The Plan authorizes the grant of stock options totaling 324,013 shares to Company directors and employees. Option awards are granted with an exercise price equal to the market price of FS Bancorp’s common stock at the grant date. May 8, 2014, of $16.89 per share. These option awards were granted as non-qualified stock options, having a vesting period of five years, with 20% vesting on the anniversary date of each grant date, and a contractual life of 10 years. Any unexercised stock options will expire 10 years after the grant date or sooner in the event of the award recipient’s termination of service with the Company or the Bank. There were no options granted in 2016 or 2015. 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 year ended December 31, 2016 (shown as actual): Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term In Years Aggregate Intrinsic Value Outstanding at January 1, 2016 306,900 $ 16.89 8.36 $ 2,794,570 Granted — — — — Less exercised 11,050 16.89 — 106,477 Forfeited or expired — — — — Outstanding at December 31, 2016 295,850 $ 16.89 7.36 $ 5,638,901 Expected to vest, assuming a 0.31% annual forfeiture rate 295,053 $ 16.89 7.36 $ 5,623,711 Exercisable at December 31, 2016 105,650 $ 16.89 7.36 $ 2,013,689 For the year ended December 31, 2016, there was $540,000 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 2.4 years. Restricted Stock Awards The Plan authorizes the grant of restricted stock awards totaling 129,605 shares to Company directors and employees, and all but 4,500 shares were granted on May 8, 2014 at a grant date fair value of $16.89 per share. The remaining 4,500 restricted stock awards were granted on 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 year ended December 31, 2016 (shown as actual): Nonvested Shares Shares Weighted-Average Grant-Date Fair Value Per Share Weighted-Average Grant-Date Fair Value Nonvested at January 1, 2016 94,684 $ 16.89 $ 1,599,212 Granted 4,500 26.00 117,000 Less vested 30,421 16.89 513,811 Forfeited or expired — — — Nonvested at December 31, 2016 68,763 $ 17.49 $ 1,202,401 For the year ended December 31, 2016, there was $ 832,000 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 2.1 years.

Accounting Policies [Abstract]
Financial Statement Presentation	Financial Statement Presentation - The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and with prevailing practices within the banking and securities industries. In preparing such financial statements, management is required to make certain estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the balance sheet and the reported amounts of revenues and expenses for the reporting period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan and lease losses, fair value of financial instruments, the valuation of servicing rights, and the deferred income taxes . Amounts presented in the consolidated financial statements and footnote tables are rounded and presented in thousands of dollars except per share amounts. In the narrative footnote discussion, amounts are rounded and presented in millions of dollars to one decimal point if the amounts are above $ 1.0 million . Amounts below $ 1.0 million are rounded and presented in dollars to the nearest thousands. Certain prior year amounts have been reclassified to conform to the 2016 presentation with no change to consolidated net income or stockholders’ equity previously reported.
Use of Estimates	In preparing such financial statements, management is required to make certain estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the balance sheet and the reported amounts of revenues and expenses for the reporting period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan and lease losses, fair value of financial instruments, the valuation of servicing rights, and the deferred income taxes .
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	Segment Reporting - The Company’s major lines of business are community banking. Management has determined that the Company operates as a single operating segment based on U.S. GAAP.
Cash and Cash Equivalents	Cash and Cash Equivalents - Cash and cash equivalents include cash and due from banks, and interest-bearing balances due from other banks and the Federal Reserve Bank of San Francisco (“FRB”) and have a maturity of 90 days or less at the time of purchase. The Company had $ 7.8 million of cash and due from banks and interest-bearing deposits at other financial institutions in excess of Federal Deposit Insurance Corporation (“FDIC”) insured limits at December 31, 2016, and none at December 31, 2015. Because the Company places these deposits with major financial institutions and monitors the financial condition of these institutions, management believes the risk of loss to any deposits in excess of FDIC limits to be minimal.
Securities Available-for-Sale	Securities Available-for-Sale - Securities available-for-sale consist of debt securities that the Company has the intent and ability to hold for an indefinite period, but not necessarily to maturity. Such securities may be sold to implement the Company’s asset/liability management strategies and in response to changes in interest rates and similar factors. Securities available-for-sale are reported at fair value. Realized gains and losses on securities available-for-sale, determined using the specific identification method, are included in results of operations. Amortization of premium and accretion of discounts are recognized in interest income over the period to maturity. Unrealized holding gains and losses, net of the related deferred tax effect, are reported as a net amount in a separate component of equity entitled accumulated other comprehensive income. Unrealized losses that are deemed to be other than temporary are reflected in results of operations. Any declines in the values of these securities that are considered to be other-than-temporary-impairment (“OTTI”) and credit-related are recognized in earnings. Noncredit-related OTTI on securities not expected to be sold is recognized in other comprehensive income. The review for OTTI is conducted on an ongoing basis and takes into account the severity and duration of the impairment, recent events specific to the issuer or industry, fair value in relationship to cost, extent and nature of change in fair value, creditworthiness of the issuer including external credit ratings and recent downgrades, trends and volatility of earnings, current analysts’ evaluations, and other key measures. In addition, the Company does not intend to sell the securities and it is more likely than not that we will not be required to sell the securities before recovery of their amortized cost basis. In doing this, we take into account our balance sheet management strategy and consideration of current and future market conditions. Dividends and interest income are recognized when earned.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock - The Bank’s investment in FHLB stock is carried at cost, which approximates fair value. As a member of the FHLB system, the Bank is required to maintain an investment in capital stock of the FHLB in an amount of $ 813,000 and 4.0% of advances from the FHLB. The Bank’s required minimum level of investment in FHLB stock is based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. At December 31, 2016 and 2015, the Bank’s minimum level of investment requirement in FHLB stock was $ 2.7 million and $ 4.6 million, respectively. The Bank was in compliance with the FHLB minimum investment requirement at December 31, 2016 and 2015. Management evaluates FHLB stock for impairment as needed. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared with the capital stock amount for the FHLB and the length of time this situation has persisted; (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB; and (4) the liquidity position of the FHLB. Based on its evaluation, management determined that there was no impairment of FHLB stock at December 31, 2016 and 2015, respectively.
Loans Held for Sale	Loans Held for Sale - The Bank records all mortgage loans held-for-sale at fair value. Fair value is determined by outstanding commitments from investors or current investor yield requirements calculated on the aggregate loan basis. Origination fees and costs are recognized in earnings at the time of origination. Mortgage loans held-for-sale are sold with the mortgage service rights either released or retained by the Bank. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loans sold. All sales are made with limited recourse against the Company.
Derivatives	Derivatives - Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free-standing derivatives. The fair value of the interest rate lock is recorded at the time the commitment to fund the mortgage loan is executed and is adjusted for the expected exercise of the commitments to fund the loans, the Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest on the loan is locked. Changes in the fair values of these derivatives are reported in “Gain on sale of loans” on the Consolidated Statements of Income.
Loans Receivable	Loans Receivable - Loans receivable, are stated at the amount of unpaid principal reduced by an allowance for loan losses and net deferred fees or costs. Interest on loans is calculated using the simple interest method based on the daily balance of the principal amount outstanding and is credited to income as earned. Loan fees, net of direct origination costs, are deferred and amortized over the life of the loan using the effective yield method. Interest on loans is accrued daily based on the principal amount outstanding. Generally, the accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due or when they are past due 90 days as to either principal or interest (based on contractual terms), unless they are well secured and in the process of collection. All interest accrued but not collected for loans that are placed on non-accrual status or charged off are reversed against interest income. Subsequent collections on a cash basis are applied proportionately to past due principal and interest, unless collectability of principal is in doubt, in which case all payments are applied to principal. Loans are returned to accrual status when the loan is deemed current, and the collectability of principal and interest is no longer doubtful, or, generally, when the loan is less than 90 days delinquent, and performing according to its contractual terms after a period of six months performance. The Company charges fees for originating loans. These fees, net of certain loan origination costs, are deferred and amortized to income, on the level-yield basis, over the loan term. If the loan is repaid prior to maturity, the remaining unamortized net deferred loan origination fee is recognized in income at the time of repayment. The Company has defined its loan portfolio into three segments that reflect the structure of the lending function, the Company’s strategic plan and the manner in which management monitors performance and credit quality. The three loan portfolio segments are: (a) Real Estate Loans, (b) Consumer Loans and (c) Commercial Business Loans. Each of these segments is disaggregated into classes based on the risk characteristics of the borrower and/or the collateral type securing the loan. Consumer, Home Equity and One-to-Four-Family Real Estate Loans Homogeneous loans are risk rated based upon the FDIC’s Uniform Retail Credit Classification and Account Management Policy. Loans classified under this policy at the Company are consumer loans which include indirect home improvement, 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 graded “ 4 ” or “5”internally. Loans that are past due more than 90 days are classified “Substandard” risk graded “ 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.
Impaired Loans	Impaired Loans - A loan is considered impaired when it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the original or modified terms of the loan agreement. Impaired loans are measured on a loan by loan basis based on the estimated fair value of the collateral less estimated cost to sell if the loan is considered collateral dependent. Impaired loans not considered to be collateral dependent are measured based on the present value of expected future cash flows. Impairment is measured for each loan in the portfolio except for the smaller groups of homogeneous consumer loans. The categories of non-accrual loans and impaired loans overlap, although they are not coextensive. The Company considers all circumstances regarding the loan and borrower on an individual basis when determining whether an impaired loan should be placed on non-accrual status, such as the financial strength of the borrower, the collateral value, reasons for delay, payment record, the amount of past due and the number of days past due. Loans that experience insignificant payment delays and payment shortfalls are generally not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of shortfall in relation to the principal and interest owed.
Troubled Debt Restructured Loans	Troubled Debt Restructured Loans - Troubled debt restructured (“TDR”) loans are loans for which the Company, for economic or legal reasons related to the borrower’s financial condition, has granted a significant concession to the borrower that it would otherwise not consider. 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 and 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.
Allowance for Loan Losses	Allowance for Loan Losses - The allowance for loan losses is maintained at a level considered adequate to provide for probable losses on existing loans based on evaluating known and inherent risks in the loan portfolio. The allowance is reduced by loans charged-off and increased by provisions charged to earnings and recoveries on loans previously charged-off. The allowance is based on management’s periodic, systematic evaluation of factors underlying the quality of the loan portfolio including changes in the size and composition of the loan portfolio, the estimated value of any underlying collateral, actual loan loss experience, current economic conditions, and detailed analysis of individual loans for which full collectability may not be assured. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. While management uses the best information available to make its estimates, future adjustments to the allowance may be necessary if there is a significant change in economic and other conditions. The appropriateness of the allowance for loan losses is estimated based on these factors and trends identified by management at the time the financial statements are prepared. When available information confirms that specific loans or portions thereof are uncollectible, these amounts are charged-off against the allowance for loan losses. The existence of some or all of the following criteria will generally confirm that a loss has been incurred: the loan is significantly delinquent and the borrower has not evidenced the ability or intent to bring the loan current; the Company has no recourse to the borrower, or if it does, the borrower has insufficient assets to pay the debt; the estimated fair value of the loan collateral is significantly below the current loan balance, and there is little or no near-term prospect for improvement. A provision of loan losses is charged against income and added to the allowance for loan losses based on regular assessment of the loan portfolio. The allowance for loan losses is allocated to certain loan categories based on the relative risk characteristics, asset classifications, and actual loss experience within the loan portfolio. Although management has allocated the allowance for loan losses to various loan portfolio segments, the allowance is general in nature and is available for the loan portfolio in its entirety. The ultimate recovery of all loans is susceptible to future market factors beyond the Company’s control. These factors may result in losses or recoveries differing significantly from those provided for in the financial statements. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations.
Reserve for Unfunded Loan Commitments	Reserve for Unfunded Loan Commitments - The reserve for unfunded loan commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to these unfunded credit facilities. The determination of the adequacy of the reserve is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. The reserve for unfunded loan commitments is included in other liabilities on the consolidated balance sheet, with changes to the balance charged against noninterest expense. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the amount of the total commitments do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate, and income-producing commercial properties.
Premises and Equipment, Net	Premises and Equipment, Net - Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The estimated useful lives used to compute depreciation include building and building improvements from 25 to 40 years and furniture, fixtures, and equipment from 3 to 10 years. Leasehold and tenant improvements are amortized using the straight-line method over the lesser of useful life or the life of the related lease. Gains or losses on dispositions are reflected in results of operations. Management reviews buildings, improvements and equipment for impairment on an annual basis or whenever events or changes in the circumstances indicate that the undiscounted cash flows for the property are less than its carrying value. If identified, an impairment loss is recognized through a charge to earnings based on the fair value of the property.
Transfers of Financial Assets and Servicing Rights	Transfers of Financial Assets - Transfers of an entire financial asset, a group of entire financial assets, or participating interest in an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Servicing Rights - Servicing assets are recognized as separate assets when rights are acquired through purchase or through sale of financial assets. Generally, purchased servicing rights are capitalized at the cost to acquire the rights. For sales of mortgage, commercial and consumer loans, a portion of the cost of originating the loan is allocated to the servicing right based on relative fair value. Fair value is based on market prices for comparable mortgage, commercial, or consumer servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds, and default rates and losses. Servicing assets are evaluated quarterly for impairment based upon the fair value of the rights as compared to amortized cost. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type, and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranches. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income. Capitalized servicing rights are stated separately on the consolidated balance sheets and are amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets.
Income Taxes	Income Taxes - The Company files a consolidated federal income tax return. Deferred federal income taxes result from temporary differences between the tax basis of assets and liabilities, and their reported amounts in the financial statements. These will result in differences between income for tax purposes and income for financial reporting purposes in future years. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established to reduce the net recorded amount of deferred tax assets if it is determined to be more likely than not, that all or some portion of the potential deferred tax asset will not be realized. The Financial Accounting Standards Board (“FASB”) issued guidance related to accounting for uncertainty in income taxes. The guidance prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It is the Company’s policy to record any penalties or interest arising from federal or state taxes as a component of income tax expense.
Employee Stock Ownership Plan (ESOP)	Employee Stock Ownership Plan ( “ ESOP ” ) - Compensation expense recognized for the Company’s ESOP equals the fair value of shares that have been allocated or committed to be released for allocation to participants. Any difference between the fair value of the shares at the time and the ESOP’s original acquisition cost is charged or credited to stockholders’ equity (additional paid-in capital). The cost of ESOP shares that have not yet been allocated or committed to be released is deducted from stockholders’ equity. Employee Stock Ownership Plan On January 1, 2012, the Company established an ESOP for eligible employees of the Company and the Bank. Employees of the Company and the Bank who have been credited with at least 1000 hours of service during a 12 -month period are eligible to participate in the ESOP.
Earnings Per Share	Earnings Per Share - Basic earnings per share (“EPS”) are computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. For purposes of computing basic and dilutive EPS, ESOP shares that have been committed to be released are outstanding and ESOP shares that have not been committed to be released shall not be considered outstanding.
Comprehensive Income (Loss)	Comprehensive Income (Loss) - Comprehensive income (loss) is comprised of net income and other comprehensive income (loss). Other comprehensive income (loss) includes items recorded directly to equity, such as unrealized holding gains and losses on securities available-for-sale.
Financial Instruments	Financial Instruments - In the ordinary course of business, the Company has entered into agreements for off-balance-sheet financial instruments consisting of commitments to extend credit and stand-by letters of credit. Such financial instruments are recorded in the financial statements when they are funded or related fees are incurred or received.
Restricted Assets	Restricted Assets - Federal Reserve regulations require that the Bank maintain reserves in the form of cash on hand and deposit balances with the FRB, based on a percentage of deposits.
Marketing and Advertising Costs	Marketing and Advertising Costs - The Company records marketing and advertising costs as expenses as they are incurred.
Stock-Baed Compensation	Stock-Based Compensation - Compensation cost is recognized for stock options and restricted stock awards, based on the fair value of these awards at the grant date. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the grant date is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.
Goodwill	Goodwill - Goodwill is recorded upon completion of a business combination as the difference between the purchase price and the fair value of net identifiable assets acquired. Goodwill was not recorded until the first quarter of 2016 in recognition of the four retail branches purchased from Bank of America. Subsequent to initial recognition, the Company tests goodwill for impairment during the fourth quarter of each fiscal year, or more often if events or circumstances, such as adverse changes in the business climate indicate there may be impairment.
Application of New Accounting Guidance and Recent Accounting Pronouncements	Application of New Accounting Guidance At October 1, 2016, the Company adopted FASB Accounting Standards Update (“ASU”) No 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . ASU 2016-09, seeks to simplify several aspects of the accounting for employee share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. As required by ASU 2016-09, all adjustments are reflected as of the beginning of the fiscal year, January 1, 2016. By applying this ASU, the Company no longer adjusts common stock for the tax impact of shares released, instead the tax impact is recognized as tax expense in the period the shares are released. This simplifies the tracking of the excess tax benefits and deficiencies, but could cause volatility in tax expense for the periods presented. The statement of cash flows has been adjusted to reflect the provisions of this ASU. The application of this ASU did not have a material impact on the consolidated financial statements. RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the FASB issued 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 revenues are 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 additional lease information on the consolidated balance sheets, however, the adoption of ASU 2016-02 is expected to increase our balance sheets by less than 5% and not to have a material impact on our regulatory capital ratios. In March 2016, the FASB issued ASU No. 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments . The ASU simplifies the embedded derivative analysis for debt instruments containing contingent call or put options by removing the requirement to assess whether a contingent event is related to interest rates or credit risks. The ASU is effective for annual periods beginning after December 15, 2016, including interim periods within those fiscal years. 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 2016, the FASB issued ASU No. 2016-07, Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting . The ASU eliminates the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an adjustment must be made to the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The ASU is effective for annual periods beginning after December 15, 2016, including interim periods within those fiscal years. 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 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . The amendments in this ASU seek to simplify several aspects of the accounting for employee share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 will be effective for the Company for annual periods beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption of the update is permitted. The early adoption of ASU 2016-09 did not have a material impact on the Company’s consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. 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 August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Receipts and Cash Payments, a consensus of the FASB’s Emerging Issues Task Force . The ASU is intended to reduce diversity in practice in how certain transactions are presented and classified in the statement of cash flows. The standard will take effect for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company does not expect this ASU to have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323) . The ASU amends the Codification for SEC staff announcements made at recent Emerging Issues Task Force (EITF) meetings. The SEC guidance that specifically relates to our Consolidated Financial Statement was from the September 2016 meeting, where the SEC staff expressed their expectations about the extent of disclosures registrants should make about the effects of the new FASB guidance as well as any amendments issued prior to adoption, on revenue (ASU 2014-09), leases (ASU 2016-02) and credit losses on financial instruments (ASU 2016-13) in accordance with SAB Topic 11.M. Registrants are required to disclose the effect that recently issued accounting standards will have on their financial statements when adopted in a future period. In cases where a registrant cannot reasonably estimate the impact of the adoption, then additional qualitative disclosures should be considered. The ASU incorporates these SEC staff views into ASC 250 and adds references to that guidance in the transition paragraphs of each of the three new standards. The adoption of this ASU did not have a material effect on the company's consolidated financial statements. 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 is of the update is permitted. The Company does not expect this ASU to have a material impact on the Company's consolidated financial statements.
Securities Available-for-Sale	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. There were 17 investments with unrealized losses of less than one year and eight investments with unrealized losses of more than one year at December 31, 2015. The unrealized losses associated with these investments are believed to be caused by changing market conditions that are considered to be temporary and the Company does not intend to sell these securities, and it is not likely to be required to sell these securities prior to maturity.

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