Accounting Policies [Abstract]
NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The consolidated financial statements of Citizens Community Federal N.A. (the “Bank”) included herein have been included by its parent company, Citizens Community Bancorp, Inc. (the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). As used in this annual report, the terms “we”, “us”, “our”, and “Citizens Community Bancorp, Inc.” mean the Company and its wholly owned subsidiary, the Bank, unless the context indicates other meaning. The Bank is a national banking association (a "National Bank") and operates under the title of Citizens Community Federal National Association ("Citizens Community Federal N.A." or "Bank"). The Company is a bank holding company, supervised by the Federal Reserve Bank of Minneapolis (the "FRB"), and operates under the title of Citizens Community Bancorp, Inc. The U.S. Office of the Comptroller of the Currency (the "OCC"), is the primary federal regulator for the Bank. The consolidated income of the Company is principally derived from the income of the Bank, the Company’s wholly owned subsidiary, serving customers primarily in Wisconsin and Minnesota through 26 branch locations, along with one branch in Michigan which the Company has a signed agreement to sell. Its primary markets include the Chippewa Valley Region in Wisconsin, the Twin Cities and Mankato markets in Minnesota, and various rural communities around these areas. The Bank offers traditional community banking services to businesses, Agricultural operators and consumers, including one-to-four family residential mortgages, as well as expanded services through Wells Insurance Agency, Inc. On September 25, 2018, the board of directors authorized a change in our fiscal year from September 30 to December 31. We sometimes refer to the three months ended December 31, 2018 as the "transition period." In this Transition Report, our fiscal years are identified according to the calendar year in which they historically ended (e.g., the fiscal years ended September 30, 2018 is referred to as "fiscal 2018," September 30, 2017 is referred to as "fiscal 2017," as if we had not changed our fiscal year to a calendar year on September 25, 2018. On January 21, 2019, the Company and F&M Merger Sub, Inc., a newly formed Minnesota corporation and wholly-owned subsidiary of the Company, entered into an Agreement and Plan of Merger (the “Merger Agreement”) with F. & M. Bancorp. of Tomah, Inc., a Wisconsin corporation ("F&M"). See Note 19, "Subsequent Events" for additional information. On December 3, 2018, the Bank entered into a Purchase and Assumption Agreement with Lake Michigan Credit Union providing for the sale of the Bank's one branch located in Rochester Hills, MI. The purchase of the branch is subject to regulatory approval and satisfaction of customary closing conditions and is expected to be completed in the second quarter of 2019. On October 19, 2018, the Company completed its previously announced acquisition (the “Acquisition”) of United Bank. See Note 2, "Acquisition" for additional information. On June 20, 2018, the Company entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with each of a limited number of institutional and other accredited investors, including certain officers and directors of the Company (collectively the “Purchasers”), pursuant to which the Company sold an aggregate of 500,000 shares of the Company’s 8.00% Series A Mandatorily Convertible Non-Cumulative Non-Voting Perpetual Preferred Stock, par value $0.01 per share, (the “Series A Preferred Stock”), in a private placement (the “Private Placement”) at $130.00 per share, for aggregate gross proceeds of $65 million , net of issuance costs of $3,735 . The Securities Purchase Agreement contains customary representations, warranties, and covenants of the Company and the Purchasers. On September 28, 2018, each share of Series A Preferred Stock was mandatorily converted into 10 shares of common stock following receipt of stockholder approval, resulting in the issuance of the 5,000,000 shares of common stock. The Bank is subject to competition from other financial institutions and non-financial institutions providing financial products. Additionally, the Bank is subject to the regulations of certain regulatory agencies and undergoes periodic examination by those regulatory agencies. In preparing these consolidated financial statements, we evaluated the events and transactions occurring subsequent to the balance sheet date of December 31, 2018 through the date on which the consolidated financial statements were available to be issued for items that should potentially be recognized or disclosed in these consolidated financial statements. For further disclosure and discussion, see Note 19, "Subsequent Events". Unless otherwise stated, all monetary amounts in these Notes to Consolidated Financial Statements, other than share, per share and capital ratio amounts, are stated in thousands. Principles of Consolidation – The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Citizens Community Federal N.A. All significant inter-company accounts and transactions have been eliminated. Use of Estimates— Preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Estimates are used in accounting for, among other items, fair value of financial instruments, the allowance for loan losses, mortgage servicing rights, foreclosed and repossessed assets, valuation of acquired intangible assets, useful lives for depreciation and amortization, indefinite-lived intangible assets. valuation of goodwill and long-lived assets, stock based compensation, deferred tax assets, uncertain income tax positions and contingencies. Management does not anticipate any material changes to estimates made herein in the near term. Factors that may cause sensitivity to the aforementioned estimates include but are not limited to: those items described under the caption “Risk Factors” in Item 1A of the accompanying transition report on Form 10-K for the year ended December 31, 2018 and external market factors such as market interest rates and employment rates, changes to operating policies and procedures, and changes in applicable banking regulations. Actual results may ultimately differ from estimates, although management does not generally believe such differences would materially affect the consolidated financial statements in any individual reporting period. Cash and Cash Equivalents— For purposes of reporting cash flows in the consolidated financial statements, cash and cash equivalents include cash, due from banks, and interest bearing deposits with original maturities of three months or less . Investment Securities; Held to Maturity and Available for Sale – Management determines the appropriate classification of investment securities at the time of purchase and reevaluates such designation as of the date of each balance sheet. Securities are classified as held to maturity when the Company has the positive intent and ability to hold the securities to maturity. Held to maturity securities are stated at amortized cost. Investment securities not classified as held to maturity are classified as available for sale. Available for sale securities are stated at fair value, with unrealized holding gains and losses being reported in other comprehensive income (loss), net of tax. Unrealized losses deemed other-than-temporary due to credit issues are reported in the Company’s net income in the period in which the losses arise. Interest income includes amortization of purchase premium or accretion of purchase discount. Amortization of premiums and accretion of discounts are recognized in interest income using the interest method over the estimated lives of the securities. The Company evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. As part of such monitoring, the credit quality of individual securities and their issuer is assessed. Significant inputs used to measure the amount of other-than-temporary impairment related to credit loss include, but are not limited to; the Company's intent and ability to sell the debt security prior to recovery, that it is more likely than not that the Company will not sell the security prior to recovery, default and delinquency rates of the underlying collateral, remaining credit support, and historical loss severities. Adjustments to market value of available for sale securities that are considered temporary are recorded in other comprehensive income or loss as separate components of stockholders' equity, net of tax. If the unrealized loss of a security is identified as other-than-temporary based on information available, such as the decline in the creditworthiness of the issuer, external market ratings, or the anticipated or realized elimination of associated dividends, such impairments are further analyzed to determine if credit loss exists. If there is a credit loss, it will be recorded in the Company's consolidated statement of operations. Non-credit components of the unrealized losses on available for sale securities will continue to be recognized in other comprehensive income (loss), net of tax. Loans – Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of unearned interest, and net of deferred loan fees and costs, and non-accretable discount on purchased of credit impaired loans. Interest income is accrued on the unpaid principal balance of these loans. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the interest method without anticipating prepayments. Late charge fees are recognized into income when collected. Interest income on commercial, mortgage and consumer loans is discontinued according to the following schedules: • Commercial/agricultural real estate loans past due 90 days or more; • Commercial/agricultural non-real estate loans past due 90 days or more; • Closed ended consumer non-real estate loans past due 120 days or more; and • Residential real estate loans and open ended consumer non-real estate loans past due 180 days or more. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual status or charged off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not received for a loan placed on nonaccrual status is reversed against interest income. Interest received on such loans is accounted for on the cash basis or cost recovery method until qualifying for return to accrual status. Loans are returned to accrual status when payments are made that bring the loan account current with the contractual term of the loan and a six month payment history has been established. Interest on impaired loans considered troubled debt restructurings (“TDRs”) or substandard, less than 90 days delinquent, is recognized as income as it accrues based on the revised terms of the loan over an established period of continued payment. Substandard loans, as defined by the OCC, our primary banking regulator, are loans that are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Residential real estate loans and open ended consumer non-real estate loans are charged off to estimated net realizable value less estimated selling costs at the earlier of when (a) the loan is deemed by management to be uncollectible, or (b) the loan becomes past due 180 days or more. Closed ended consumer non-real estate loans are charged off to net realizable value at the earlier of when (a) the loan is deemed by management to be uncollectible, or (b) the loan becomes past due 120 days or more. Commercial/agricultural real estate and non-real estate loans are charged off to net realizable value at the earlier of when (a) the loan is deemed by management to be uncollectible, or (b) the loan becomes past due 90 days or more. Allowance for Loan Losses – The allowance for loan losses (“ALL”) is a valuation allowance for probable and inherent credit losses in our loan portfolio. Loan losses are charged against the ALL when management believes that the collectability of a loan balance is unlikely. Subsequent recoveries, if any, are credited to the ALL. Management estimates the required ALL balance taking into account the following factors: past loan loss experience; the nature, volume and composition of our loan portfolio; known and inherent risks in our portfolio; information about specific borrowers’ ability to repay; estimated collateral values; current economic conditions; and other relevant factors determined by management. The ALL consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers non-impaired loans and is based on historical loss experience adjusted for certain qualitative factors. The entire ALL balance is available for any loan that, in management’s judgment, should be charged off. A loan is impaired when full payment under the loan terms is not expected. Impaired loans consist of all TDRs, as well as individual loans not considered a TDR, that are either (1) rated substandard or worse, (2) on nonaccrual status or (3) PCI loans which are impaired at the time of acquisition. All TDRs are individually evaluated for impairment. See Note 4, “Loans, Allowance for Loan Losses and Impaired Loans” for more information on what we consider to be a TDR. For TDR's or substandard loans deemed to be impaired, a specific ALL allocation may be established so that the loan is reported, net, at the lower of (a) its outstanding principal balance; (b) the present value of the loan's estimated future cash flows using the loan’s existing rate; or (c) at the fair value of any loan collateral, less estimated disposal costs, if repayment is expected solely from the underlying collateral of the loan. For TDRs less than 90+ days past due, and certain substandard loans that are less than 90+ days delinquent, the likelihood of the loan migrating to over 90 days past due is also taken into account when determining the specific ALL allocation for these particular loans. Large groups of smaller balance homogeneous loans, such as non-TDR commercial, consumer and residential real estate loans, are collectively evaluated for ALL purposes, and accordingly, are not separately identified for ALL disclosures. Acquired Loans— Loans acquired in connection with acquisitions are recorded at their acquisition-date fair value with no carryover of related allowance for credit losses. Any allowance for loan loss on these pools reflect only losses incurred after the acquisition (meaning the present value of all cash flows expected at acquisition that ultimately are not to be received). Determining the fair value of the acquired loans involves estimating the principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. Management considers a number of factors in evaluating the acquisition-date fair value including the remaining life of the acquired loans, delinquency status, estimated prepayments, payment options and other loan features, internal risk grade, estimated value of the underlying collateral and interest rate environment. Acquired loans that met the criteria for nonaccrual of interest prior to the acquisition may be considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if we can reasonably estimate the timing and amount of the expected cash flows on such loans and if we expect to fully collect the new carrying value of the loans. As such, we may no longer consider the loan to be nonaccrual or nonperforming and may accrue interest on these loans, including the impact of any accretable yield. Loans acquired with deteriorated credit quality are accounted for in accordance with Accounting Standards Codification (“ASC”) 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (ASC 310-30) if, at acquisition, the loans have evidence of credit quality deterioration since origination and it is probable that all contractually required payments will not be collected. At acquisition, the Company considers several factors as indicators that an acquired loan has evidence of deterioration in credit quality. These factors include; loans 90 days or more past due, loans with an internal risk grade of substandard or below, loans classified as non-accrual by the acquired institution, and loans that have been previously modified in a troubled debt restructuring. Under the ASC 310-30 model, the excess of cash flows expected to be collected at acquisition over recorded fair value is referred to as the accretable yield and is the interest component of expected cash flow. The accretable yield is recognized into income over the remaining life of the loan if the timing and/or amount of cash flows expected to be collected can be reasonably estimated (the accretion method). If the timing or amount of cash flows expected to be collected cannot be reasonably estimated, the cost recovery method of income recognition is used. The difference between the loan’s total scheduled principal and interest payments over all cash flows expected to be collected at acquisition, considering the impact of prepayments, is referred to as the non-accretable difference. The non-accretable difference represents contractually required principal and interest payments which the Company does not expect to collect. Over the life of the loan, management continues to estimate cash flows expected to be collected. Decreases in expected cash flows are recognized as impairments through a charge to the provision for loan losses resulting in an increase in the allowance for loan losses. Subsequent improvements in cash flows result in first, reversal of existing valuation allowances recognized subsequent to acquisition, if any, and next, an increase in the amount of accretable yield to be subsequently recognized in interest income on a prospective basis over the loan’s remaining life. Acquired loans that were not individually determined to be purchased with deteriorated credit quality are accounted for in accordance with ASC 310-20, Nonrefundable Fees and Other Costs (ASC 310-20), whereby the premium or discount derived from the fair market value adjustment, on a loan-by-loan or pooled basis, is recognized into interest income on a level yield basis over the remaining expected life of the loan or pool. For all acquired loans, the outstanding loan balances less any related accretable yield and/or non-accretable difference is referred to as the loans' carrying amount. Loans Held for Sale — Loans held for sale are those loans the Company has the intent to sell in the foreseeable future. They are carried at the lower of aggregate cost or fair value. Gains and losses on sales of loans are recognized at settlement dates, and are determined by the difference between the sales proceeds and the carrying value of the loans after allocating costs to servicing rights retained. All sales are made without recourse. Interest rate lock commitments on mortgage loans to be funded and sold are valued at fair value, and are included in other assets or liabilities, if material. Mortgage Servicing Rights— Mortgage servicing rights ("MSR") assets result as the Company sells loans to investors in the secondary market and retains the rights to service mortgage loans sold to others. MSR assets are initially measured at fair value; assessed at least annually for impairment; carried at the lower of the initial capitalized amount, net of accumulated amortization, or estimated fair value. MSR assets are amortized in proportion to and over the period of estimated net servicing income, with the amortization recorded in non-interest expense in the consolidated statement of operations. The valuation of MSRs and related amortization thereon are based on numerous factors, assumptions and judgments, such as those for: changes in the mix of loans, interest rates, prepayment speeds, and default rates. Changes in these factors, assumptions and judgments may have a material effect on the valuation and amortization of MSRs. Although management believes that the assumptions used to evaluate the MSRs for impairment are reasonable, future adjustment may be necessary if future economic conditions differ substantially from the economic assumptions used to determine the value of MSRs. Non-marketable Equity Securities — Non-marketable equity securities are comprised of Federal Home Loan Bank (FHLB) stock and Federal Reserve Bank (FRB) stock, and are carried at cost. The Bank is a member of the FHLB system. Members are required to own a certain amount of FHLB stock based on the Bank’s level of borrowings from the FHLB and other factors, and may invest in additional amounts of FHLB stock. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on the ultimate recovery of par value. The determination of whether a decline affects the ultimate recovery is influenced by criteria such as: (1) the significance of the decline in net assets of the FHLB as compared to the capital stock amount and length of time a decline has persisted; (2) the impact of legislative and regulatory changes on the FHLB; and (3) the liquidity position of the FHLB. Cash dividends are reported as income. FHLB stock is evaluated quarterly for impairment. Quarterly cash dividends are paid on FHLB stock owned by members as a condition for required membership and also paid on stock owned by members based on activity. Based on management’s quarterly evaluation, no impairment has been recorded on these securities. As a National Banking Association, the Bank must be a member of the Federal Reserve system. Each member bank is required to subscribe to Federal Reserve Stock in an amount equal to 6 percent of its capital and surplus. Although the par value of the stock is $100 per share, banks (including the Bank) pay only $50 per share at the time of purchase, with the understanding that the other half of the subscription amount is subject to call at any time. Dividends are paid at the statutory rate of 6 percent per annum, or $1.50 per share semi-annually on the last business day of June and December. Foreclosed and Repossessed Assets, net – Assets acquired through foreclosure or repossession are initially recorded at fair value, less estimated costs to sell, which establishes a new cost basis. If the fair value declines subsequent to foreclosure or repossession, a write-down is recorded through expense. Costs incurred after acquisition are expensed and are included in non-interest expense, other in the Consolidated Statements of Operations. Transfers of financial assets— Transfers of financial assets 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 entity, (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 entity does not maintain effective control over the transferred assets through an agreement to repurchase them before maturity. Goodwill and other intangible assets— The Company accounts for goodwill and other intangible assets in accordance with ASC Topic 350, "Intangibles - Goodwill and Other." The Company records the excess of the cost of acquired entities over the fair value of identifiable tangible and intangible assets acquired, less liabilities assumed, as goodwill. The Company amortizes acquired intangible assets with definite useful economic lives over their useful economic lives utilizing the straight-line method. On a periodic basis, management assesses whether events or changes in circumstances indicate that the carrying amounts of the intangible assets may be impaired. The Company does not amortize goodwill and any acquired intangible asset with an indefinite useful economic life, but reviews them for impairment at a reporting unit level on an annual basis, or when events or changes in circumstances indicate that the carrying amounts may be impaired. A reporting unit is defined as any distinct, separately identifiable component of the Company’s one operating segment for which complete, discrete financial information is available and reviewed regularly by the segment’s management. The Company has one reporting unit as of December 31, 2018 which is related to its banking activities. The Company has performed the required goodwill impairment test and has determined that goodwill was not impaired as of December 31, 2018 . Office Properties and Equipment— Premises and equipment are stated at cost less accumulated depreciation. Land is carried at cost. Maintenance and repair costs are charged to expense as incurred. Gains or losses on disposition of office properties and equipment are reflected in income. Buildings and related components are depreciated using the straight-line method with useful lives ranging from 10 to 40 years. Furniture, fixtures and equipment are depreciated using the straight-line (or accelerated) method with useful lives ranging from 3 to 10 years. Leasehold improvements are depreciated using the straight-line (or accelerated) method with useful lives based on the lesser of (a) the estimated life of the lease, or (b) the estimated useful life of the leasehold improvement. Interest Bearing Deposits— Other interest bearing deposits are certificate of deposit investments made by the Bank with other financial institutions that are carried at cost. The weighted average months to maturity of the interest bearing deposits is 19.91 months . Balances over $250 in those institutions are not insured by the FDIC and therefore pose a potential risk in the event the institution were to fail. As of December 31, 2018 , September 30, 2018 and September 30, 2017, there was one certificate of deposit with a balance of $251 . Debt and equity issuance costs— Debt issuance costs, which consist primarily of fees paid to note lenders, are deferred and included in other borrowings in the consolidated balance sheet. Debt issuance costs are amortized over the contractual term of the corresponding debt, as a component of interest expense on other borrowed funds in the consolidated statement of operations. Specific costs associated with the issuance of shares of the Company's common or preferred stock are netted against proceeds and recorded in stockholders' equity, as additional paid in capital, on the consolidated balance sheet, in the period of the share issuance. Advertising, Marketing and Public Relations Expense— The Company expenses all advertising, marketing and public relations costs as they are incurred. Income Taxes – The Company accounts for income taxes in accordance with the Financial Accounting Standards Board (FASB) Accounting Standards Codification (“ASC”) Topic 740, “Income Taxes.” Under this guidance, deferred taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates that will apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date. See Note 14, "Income Taxes" for details on the Company’s income taxes. The Tax Cuts and Jobs Act of 2017 ("Tax Act"), enacted on December 22, 2017, reduces corporate Federal income tax rates for the Company from 34% to 24.5% for fiscal 2018, and 21% for periods after September 30, 2018. GAAP requires the impact of the provisions of the Tax Act be accounted for in the period of enactment. At December 31, 2017, we had not completed our accounting for the tax effects of enactment of the Tax Act; however, in certain cases, as described below, we made a reasonable estimate and continue to account for those items based on our existing accounting under ASC 740, Income Taxes, and the provisions of the tax laws that were in effect immediately prior to enactment. The Company revalued its net deferred tax assets to account for the future impact of lower corporate taxes. For the items for which we were able to determine a reasonable estimate, we recorded an increased provisional amount of income tax expense of $275 in December 2017, related to the revaluation of the deferred tax assets to both the revaluation of timing differences and the unrealized loss on securities. In the fourth quarter of fiscal 2018, based on updated information obtained in connection with the filing of our tax return and analysis of our net deferred tax asset both from the return and 2018 tax provisions, we finalized the tax analysis and recorded an additional $63 of expense, or a net increase in our tax provision for the year of $338 related to the Tax Act. The Company regularly reviews the carrying amount of its net deferred tax assets to determine if the establishment of a valuation allowance is necessary. If based on the available evidence, it is more likely than not that all or a portion of the Company’s net deferred tax assets will not be realized in future periods, a deferred tax valuation allowance would be established. Consideration is given to various positive and negative factors that could affect the realization of the deferred tax assets. In evaluating this available evidence, management considers, among other things, historical performance, expectations of future earnings, the ability to carry back losses to recoup taxes previously paid, the length of statutory carry forward periods, any experience with utilization of operating loss and tax credit carry forwards not expiring, tax planning strategies and timing of reversals of temporary differences. Significant judgment is required in assessing future earnings trends and the timing of reversals of temporary differences. Accordingly, the Company’s evaluation is based on current tax laws as well as management’s expectations of future performance. Revenue Recognition - The Company recognizes revenue in the consolidated statements of operations as it is earned and when collectability is reasonably assured. The primary source of revenue is interest income from interest earning assets, which is recognized on the accrual basis of accounting using the effective interest method. The recognition of revenues from interest earning assets is based upon formulas from underlying loan agreements, securities contracts or other similar contracts. Non-interest income is recognized on the accrual basis of accounting as services are provided or as transactions occur. Non-interest income includes fees from brokerage and advisory service, deposit accounts, merchant services, ATM and debit card fees, mortgage banking activities, and other miscellaneous services and transactions. Commission revenue is recognized as of the effective date of the insurance policy or the date the customer is billed, whichever is later. The Company also receives contingent commissions from insurance companies which are based on the overall profitability of their relationship based primarily on the loss experience of the insurance placed by the Company. Contingent commissions from insurance companies are recognized when determinable. Commission revenue is included in other non-interest income in the consolidated statement of operations. Earnings Per Share – Basic earnings per common share is net income or loss divided by the weighted average number of common shares outstandin

Business Combinations [Abstract]
ACQUISITION	ACQUISITION United Bank On October 19, 2018, the Company completed its previously announced acquisition of United Bank pursuant to the stock purchase agreement, dated June 20, 2018, as then amended. In connection with the acquisition, the Company merged United Bank with and into the Bank, with the Bank surviving the merger. Under the terms of the stock purchase agreement, the Company acquired 100% of the common stock of United Bank from United Bancorporation for the purchase price of $51.1 million , which includes approximately $400 in closing date purchase price adjustments as provided in the Stock Purchase Agreement, as amended. Of the cash consideration to be paid to United Bancorporation in the Acquisition, approximately $44.3 million was paid in cash upon the closing of the Acquisition, and approximately $6.8 million was set aside in escrow or held by the Company for the purposes of funding certain post-closing purchase price adjustments and future indemnity claims in accordance with the Stock Purchase Agreement, as amended. The merger added $315,216 in assets, $199,859 in loans, $272,671 in deposits, $21,030 in goodwill, and $3,020 in core deposit intangible. Acquired deposits included approximately $51,000 , deposited by United Bank's former parent company, and withdrawn from the Bank, as anticipated, subsequent to the acquisition. None of the goodwill is deductible for tax purposes, as the acquisition is accounted for as a tax-free exchange for tax purposes. In connection with the United Bank acquisition, we incurred expenses related to (1) accounting, legal and other professional services, (2) contract termination costs, and (3) other costs of integrating and conforming acquired operations with and into the Company. These merger-related expenses, that were expensed as incurred, amounted to $1,057 for the three months ended December 31, 2018 and $359 for the year ended September 30, 2018, and were included in non-interest expense on the consolidated statement of operations. The acquisition of the net assets of United constitutes a business combination as defined by FASB ASC Topic 805, " Business Combinations ." Accordingly, the assets acquired and liabilities assumed are presented at their fair values at acquisition date. Fair values were determined based on the requirements of FASB ASC Topic 820, " Fair Value Measurements ." In many cases, the determination of these fair values required management to make estimates regarding discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change for a period up to 12 months after the acquisition date. Management engaged third-party valuation specialists to assist in determining such values. The preliminary results of the fair value evaluation generated goodwill and intangible assets as noted above. The following pro forma financial information for the periods presented reflects our estimated consolidated pro forma results of operations as if the United acquisition occurred on October 1, 2018, not considering potential cost savings and other business synergies we expect to receive as a result of the acquisition: Citizens Community Bancorp, Inc.

The revenue and earnings of United Bank since the acquisition date of October 19, 2018 are included in the Company's consolidated statement of operations, and it is not practical to disclose them separately.

However, as of December 31, 2018 , there were no borrowings outstanding on this Federal Reserve Bank line of credit. As of December 31, 2018 , the Bank has pledged certain of its U.S. Government Agency securities with a carrying value of $5,574 and mortgage-backed securities with a carrying value of $23,351 as collateral against specific municipal deposits. As of December 31, 2018 , the Bank also has mortgage backed securities with a carrying value of $931 pledged as collateral to the Federal Home Loan Bank of Des Moines. The estimated fair value of available for sale securities at December 31, 2018 , by contractual maturity, is shown below. Expected maturities will differ from contractual maturities on mortgage-backed securities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

As part of such monitoring, the credit quality of individual securities and their issuer is assessed. Significant inputs used to measure the amount of other-than-temporary impairment related to credit loss include, but are not limited to; the Company's intent and ability to sell the debt security prior to recovery, that it is more likely than not that the Company will not sell the security prior to recovery, default and delinquency rates of the underlying collateral, remaining credit support, and historical loss severities. Adjustments to market value of available for sale securities that are considered temporary are recorded as separate components of shareholders' equity, net of tax. If the unrealized loss of a security is identified as other-than-temporary based on information available, such as the decline in the creditworthiness of the issuer, external market ratings, or the anticipated or realized elimination of associated dividends, such impairments are further analyzed to determine if credit loss exists. If there is a credit loss, it will be recorded in the Company's consolidated statement of operations. Non-credit components of the unrealized losses on available for sale securities will continue to be recognized in other comprehensive income (loss), net of tax. Unrealized losses reflected in the preceding tables have not been included in results of operations because the unrealized loss was not deemed other-than-temporary. Management has determined that more likely than not, the Company neither intends to sell, nor will it be required to sell each debt security before its anticipated recovery, and therefore recovery of cost will occur.

Under consumer home equity loan guidelines, the borrower will be approved for a loan based on a percentage of their home's appraised value less the balance owed on the existing first mortgage. Credit risk is minimized within the residential real estate portfolio as relatively small loan amounts are spread across many individual borrowers. Management evaluates trends in past due loans and current economic factors such as the housing price index on a regular basis. Commercial and agricultural real estate loans are underwritten after evaluating and understanding the borrower's ability to operate profitably and prudently expand its business. Management examines current and projected cash flows to determine the ability of the borrower to repay its obligations as agreed. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally largely dependent on the successful operation of the property or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The level of owner-occupied property versus non-owner-occupied property are tracked and monitored on a regular basis. Agricultural real estate loans are primarily comprised of loans for the purchase of farmland. Loan-to-value ratios on loans secured by farmland generally do not exceed 75%. Consumer non-real estate loans are comprised of originated indirect paper loans secured primarily by boats and recreational vehicles, purchased indirect paper loans secured primarily by household goods and other consumer loans secured primarily by automobiles and other personal assets. The Bank ceased new originations of these types of loans in early fiscal 2017. Consumer loans underwriting terms often depend on the collateral type, debt to income ratio and the borrower's creditworthiness as evidenced by their credit score. Collateral value alone may not provide an adequate source of repayment of the outstanding loan balance in the event of a consumer non-real estate default. This shortage is a result of the greater likelihood of damage, loss and depreciation for consumer based collateral. Commercial non-real estate loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. These cash flows, however, may not be as expected and the value of collateral securing the loans may fluctuate. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee. Agricultural non-real estate loans are generally comprised of term loans to fund the purchase of equipment, livestock and seasonal operating lines. Operating lines are typically written for one year and secured by the crop and other farm assets as considered necessary. Agricultural loans carry significant credit risks as they may involve larger balances concentrated with single borrowers or groups of related borrowers. In addition, repayment of such loans depends on the successful operation or management of the farm property securing the loan or for which an operating loan is utilized. Farming operations may be affected by adverse weather conditions such as drought, hail or floods that can severely limit crop yields.

net deferred fees and costs and loans in process 1,471 Unamortized discount on acquired loans (5,089 ) Allowance for loan losses (5,942 ) Loans receivable, net $ 727,053 Credit Quality/Risk Ratings: Management utilizes a numeric risk rating system to identify and quantify the Bank’s risk of loss within its loan portfolio. Ratings are initially assigned prior to funding the loan, and may be changed at any time as circumstances warrant. Ratings range from the highest to lowest quality based on factors that include measurements of ability to pay, collateral type and value, borrower stability and management experience. The Bank’s loan portfolio is presented below in accordance with the risk rating framework that has been commonly adopted by the federal banking agencies. The definitions of the various risk rating categories are as follows: 1 through 4 - Pass. A "Pass" loan means that the condition of the borrower and the performance of the loan is satisfactory or better. 5 - Watch. A "Watch" loan has clearly identifiable developing weaknesses that deserve additional attention from management. Weaknesses that are not corrected or mitigated, may jeopardize the ability of the borrower to repay the loan in the future. 6 - Special Mention. A "Special Mention" loan has one or more potential weakness that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the institution’s credit position in the future. 7 - Substandard. A "Substandard" loan is inadequately protected by the current net worth and paying capacity of the obligor or the collateral pledged, if any. Assets classified as substandard must have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. 8 - Doubtful. A "Doubtful" loan has all the weaknesses inherent in a Substandard loan with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. 9 - Loss. Loans classified as "Loss" are considered uncollectible, and their continuance as bankable assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, and a partial recovery may occur in the future. Certain directors and executive officers of the Company are defined as related parties. These related parties, including their immediate families and companies in which they are principal owners, were loan customers of the Bank during the three months ended December 31, 2018 , and the years ended September 30, 2018 and September 30, 2017. A summary of the changes in those loans is as follows: December 31, 2018 September 30, 2018 September 30, 2017 Balance—beginning of year $ 234 $ 596 $ 221 New loan originations 12 — 2 Repayments (124 ) (257 ) (13 ) Acquired previously originated director loans 10,982 — — Previously originated loans for new director — — 386 Previously originated loans for previous director — (105 ) — Balance—end of year $ 11,104 $ 234 $ 596 Available and unused lines of credit $ 37 $ 17 $ 18 Allowance for Loan Losses —The ALL represents management’s estimate of probable and inherent credit losses in the Bank’s loan portfolio. Estimating the amount of the ALL requires the exercise of significant judgment and the use of estimates related to the amount and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans based on historical loss experience, and consideration of other qualitative factors such as current economic trends and conditions, all of which may be susceptible to significant change. There are many factors affecting the ALL; some are quantitative, while others require qualitative judgment. The process for determining the ALL (which management believes adequately considers potential factors which result in probable credit losses), includes subjective elements and, therefore, may be susceptible to significant change. To the extent actual outcomes differ from management estimates, additional provision for loan losses could be required that could adversely affect the Company’s earnings or financial position in future periods. Allocations of the ALL may be made for specific loans but the entire ALL is available for any loan that, in management’s judgment, should be charged-off or for which an actual loss is realized. As an integral part of their examination process, various regulatory agencies also review the Bank’s ALL. Such agencies may require that changes in the ALL be recognized when such regulators’ credit evaluations differ from those of our management based on information available to the regulators at the time of their examinations. Changes in the ALL by loan type for the periods presented below were as follows: Residential Real Estate Commercial/Agriculture Real Estate Consumer Non-real Estate Commercial/Agricultural Non-real

Deferred Costs, Capitalized, Prepaid, and Other Assets Disclosure [Abstract]
CAPITAL MATTERS	CAPITAL MATTERS Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. Although these terms are not used to represent overall financial condition, if adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At December 31, 2018 , the Bank and Company were categorized as “Well Capitalized”, under Prompt Corrective Action Provisions. The Bank’s Tier 1 (leverage) and risk-based capital ratios at December 31, 2018 , September 30, 2018 and 2017 , respectively, are presented below: Actual For Capital Adequacy To Be Well Capitalized Amount Ratio Amount Ratio Amount Ratio As of December 31, 2018 Total capital (to risk weighted assets) $ 126,440,000 12.7 % $ 79,651,000 > = 8.0 % $ 99,563,000 > = 10.0 % Tier 1 capital (to risk weighted assets) 118,836,000 11.9 % 59,738,000 > = 6.0 % 79,651,000 > = 8.0 % Common equity tier 1 capital (to risk weighted assets) 118,836,000 11.9 % 44,804,000 > = 4.5 % 64,716,000 > = 6.5 % Tier 1 leverage ratio (to adjusted total assets) 118,836,000 9.7 % 48,976,000 > = 4.0 % 61,220,000 > = 5.0 % As of September 28, 2018 Total capital (to risk weighted assets) $ 95,799,000 13.1 % $ 58,614,000 > = 8.0 % $ 73,268,000 > = 10.0 % Tier 1 capital (to risk weighted assets) 89,051,000 12.2 % 43,961,000 > = 6.0 % 58,614,000 > = 8.0 % Common equity tier 1 capital (to risk weighted assets) 89,051,000 12.2 % 32,971,000 > = 4.5 % 47,624,000 > = 6.5 % Tier 1 leverage ratio (to adjusted total assets) 89,051,000 9.2 % 38,765,000 > = 4.0 % 48,456,000 > = 5.0 % As of September 30, 2017 Total capital (to risk weighted assets) $ 88,511,000 13.2 % $ 53,504,000 > = 8.0 % $ 66,880,000 > = 10.0 % Tier 1 capital (to risk weighted assets) 82,569,000 12.4 % 40,128,000 > = 6.0 % 53,504,000 > = 8.0 % Common equity tier 1 capital (to risk weighted assets) 82,569,000 12.4 % 30,096,000 > = 4.5 % 43,472,000 > = 6.5 % Tier 1 leverage ratio (to adjusted total assets) 82,569,000 9.2 % 35,776,000 > = 4.0 % 44,720,000 > = 5.0 % The Company's Tier 1 (leverage) and risk-based capital ratios at December 31, 2018 , September 30, 2018 and September 30, 2017 , respectively, are presented below: Actual For Capital Adequacy To Be Well Capitalized Amount Ratio Amount Ratio Amount Ratio As of December 31, 2018 Total capital (to risk weighted assets) $ 123,657,000 12.4 % $ 79,651,000 > = 8.0 % $ 99,563,000 > = 10.0 % Tier 1 capital (to risk weighted assets) 101,053,000 10.2 % 59,738,000 > = 6.0 % 79,651,000 > = 8.0 % Common equity tier 1 capital (to risk weighted assets) 101,053,000 10.2 % 44,804,000 > = 4.5 % 64,716,000 > = 6.5 % Tier 1 leverage ratio (to adjusted total assets) 101,053,000 8.3 % 48,976,000 > = 4.0 % 61,220,000 > = 5.0 % As of September 28, 2018 Total capital (to risk weighted assets) $ 145,052,000 19.8 % $ 58,614,000 > = 8.0 % $ 73,268,000 > = 10.0 % Tier 1 capital (to risk weighted assets) 123,304,000 16.8 % 43,961,000 > = 6.0 % 58,614,000 > = 8.0 % Common equity tier 1 capital (to risk weighted assets) 123,304,000 16.8 % 32,971,000 > = 4.5 % 47,624,000 > = 6.5 % Tier 1 leverage ratio (to adjusted total assets) 123,304,000 12.7 % 38,765,000 > = 4.0 % 48,456,000 > = 5.0 % As of September 30, 2017 Total capital (to risk weighted assets) $ 79,889,000 12.0 % $ 53,504,000 > = 8.0 % $ 66,880,000 > = 10.0 % Tier 1 capital (to risk weighted assets) 58,947,000 8.8 % 40,128,000 > = 6.0 % 53,504,000 > = 8.0 % Common equity tier 1 capital (to risk weighted assets) 58,947,000 8.8 % 30,096,000 > = 4.5 % 43,472,000 > = 6.5 % Tier 1 leverage ratio (to adjusted total assets) 58,947,000 6.6 % 35,776,000 > = 4.0 % 44,720,000 > = 5.0 % On June 20, 2018, the Company entered into a Securities Purchase Agreement, pursuant to which the Company sold an aggregate of 500,000 shares of Series A Preferred Stock in a private placement at $130.00 per share, for aggregate gross proceeds of $65,000 , less issuance costs of $3,735 .

For further information, refer to Note 1, "Nature of Business and Summary of Significant Accounting Policies". The Company is a legal entity separate and distinct from its banking subsidiary. As a bank holding company, the Company is subject to certain restrictions on its ability to pay dividends under applicable banking laws and regulations. Federal bank regulators are authorized to determine under certain circumstances relating to the financial condition of a bank holding company or a bank that the payment of dividends would be an unsafe or unsound practice and to prohibit payment thereof. In particular, federal bank regulators have stated that paying dividends that deplete a banking organization’s capital base to an inadequate level would be an unsafe and unsound banking practice and that banking organizations should generally pay dividends only out of current operating earnings. In addition, in the current financial and economic environment, the Federal Reserve has indicated that bank holding companies should carefully review their dividend policy and has discouraged payment ratios that are at maximum allowable levels unless both asset quality and capital are very strong. The Company's ability to pay dividends is also subject to the terms of the Business Note Agreement dated August 1, 2018, which prohibits the Company from making dividend payments while an event of default has occurred and is continuing under the loan agreement or from allowing payment of a dividend which would create an event of default. The following table reflects the annual cash dividend paid in the three months ended ended December 31, 2018 and years ended September 30, 2018 and 2017 respectively.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Financial Instruments with Off-Balance-Sheet Risk— The Company is a 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 off-balance-sheet credit instruments consisting of commitments to make loans. The face amounts for these items represent the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. 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 contract or notional 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. Set forth below are the balances of the Company’s off-balance-sheet credit instruments consisting of commitments to make loans as of December 31, 2018 , September 30, 2018 and September 30, 2017 , respectively. Contract or Notional Contract or Notional 2018 2018 2017 Commitments to extend credit $ 204,683 $ 121,197 $ 78,150 Commercial standby letter of credit $ 3,118 $ 1,893 $ 1,644 Commitments to extend credit are agreements to lend to a customer provided 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 total commitment amounts do not necessarily represent future cash requirements. Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. The Company evaluates each customer's credit worthiness on a case-by-case basis. The credit and collateral policy for commitments and letters of credit is comparable to that for granting loans. Loss Contingencies— Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Leases— The Company leases certain branch facilities and its administrative offices under operating leases. Rent expense under these operating leases was $237 , $879 and $1,310 for the three months ended December 31, 2018 , and the years ended September 30, 2018 and September 30, 2017 , respectively. None of the Company’s leases contain contingent rental payments, purchase options, escalation or any other significant terms, conditions or restrictions that would affect the future minimum lease payments disclosed below. Future minimum lease payments by year and in the aggregate under the original terms of the non-cancellable operating leases consist of the following: 2019 $ 948 2020 925 2021 809 2022 776 2023 705 After 2023 2,050 Total $ 6,213

RETIREMENT PLANS	RETIREMENT PLANS 401(k) Plan— The Company sponsors a 401(k) profit sharing plan that covers all employees who qualify based on minimum age and length of service requirements. Employees may make pretax voluntary contributions to the plan, which are matched, in part, by the Company. Employer matching contributions to the plan were $126 , $383 and $278 for the three months ended December 31, 2018 and the years ended September 30, 2018 and September 30, 2017 , respectively. Supplemental Executive Retirement Plan and Director Retirement Plan — The Company maintained a Supplemental Benefit Plan For Key Employees ("SERP") which was an unfunded, unsecured, non-contributory defined benefit plan, providing retirement benefits for certain former key employees previously designated by the Company’s Board of Directors. Benefits under the SERP generally were based on such former employees’ years of service and compensation during the years preceding their retirement. In May 2009, any additional accrual of benefits under the SERP was suspended. The Company also maintained a Directors’ Retirement Plan ("DRP"), which was an unfunded, unsecured, non-contributory defined benefit plan, providing for supplemental pension benefits for its directors following their termination of service as a director of the Company. Benefits were based on a formula that included each participant’s past and future earnings and years of service with Citizens. Moreover, the benefit amounts owed by the Company under the DRP were determined by individual director agreements entered into by the Company with such participants. The remaining DRP liability related to current and former Directors of the Company. The Company's Board of Directors voted to terminate each of the SERP and the DRP at its regularly scheduled Board meeting on November 19, 2015, with such termination being effective as of the same date. In connection with the termination of each plan, the Board of Directors, in accordance with applicable law and each applicable participant’s plan participation agreement, negotiated lump sum payments to the participants in satisfaction of the Company’s total liability to each participant under the SERP and DRP. In accordance with the final settlement of the Company’s obligations under such plans, the Company made two payments (each for 50% of the total liability owed) to each plan participant. The first payment occurred in December 2016 and the second and final payment occurred in January 2017, totaling $1,046 for the aggregate amount of the benefit obligation due.

At December 31, 2018 , September 30, 2018 and September 30, 2017, respectively, management determined that no valuation allowance was necessary. The Company’s income tax returns are subject to review and examination by federal, state and local government authorities. As of December 31, 2018 , years open to examination by the U.S. Internal Revenue Service include taxable years ended September 30, 2015 to present. The years open to examination by state and local government authorities varies by jurisdiction. The tax effects from uncertain tax positions can be recognized in the consolidated financial statements, provided the position is more likely than not to be sustained on audit, based on the technical merits of the position. The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized, upon ultimate settlement with the relevant tax authority. The Company applied the foregoing accounting standard to all of its tax positions for which the statute of limitations remained open as of the date of the accompanying consolidated financial statements. The Company’s policy is to recognize interest and penalties related to income tax issues as components of other noninterest expense. During the transition period ended December 31, 2018 and the years ended September 30, 2018 and 2017 , the Company recognized penalties and interest expense in the amount of $0 for each period, related to income tax issues which is included in other noninterest expense in its consolidated statements of operations. The Company had a recorded liability of $9 , $9 and $11 , which is included in other liabilities in its consolidated balance sheets, for the payment of interest and penalties related to income tax issues as of December 31, 2018 , September 30, 2018 and 2017 , respectively.

Fair Value Accounting

Fair Value Disclosures [Abstract]
FAIR VALUE ACCOUNTING	FAIR VALUE ACCOUNTING ASC Topic 820-10, “ Fair Value Measurements and Disclosures ” establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The topic describes three levels of inputs that may be used to measure fair value: Level 1- Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Company has the ability to access as of the measurement date. Level 2- Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3- Significant unobservable inputs that reflect the Company’s assumptions about the factors that market participants would use in pricing an asset or liability. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input within the valuation hierarchy that is significant to the fair value measurement. The fair value of securities available for sale is determined by obtaining market price quotes from independent third parties wherever such quotes are available (Level 1 inputs); or matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities' relationship to other benchmark quoted securities (Level 2 inputs). Where such quotes are not available, we utilize independent third party valuation analysis to support our own estimates and judgments in determining fair value (Level 3 inputs). Assets Measured on a Recurring Basis The following tables present the financial instruments measured at fair value on a recurring basis as of December 31, 2018 , September 30, 2018 and 2017 . Fair Value Quoted Prices in Active Markets for Identical Instruments (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2018 Investment securities: U.S. government agency obligations $ 45,298 $ — $ 45,298 $ — Obligations of states and political subdivisions 34,728 — 34,728 — Mortgage-backed securities 41,350 — 41,350 — Agency Securities 148 — 148 — Corporate debt securities 6,305 — 6,305 — Corporate asset based securities 18,896 — 18,896 — Total $ 146,725 $ — $ 146,725 $ — September 30, 2018 Investment securities: U.S. government agency obligations $ 34,603 $ — $ 34,603 $ — Obligations of states and political subdivisions 34,554 — 34,554 — Mortgage-backed securities 41,371 — 41,371 — Agency Securities 182 — 182 — Corporate debt securities 6,276 — 6,276 — Corporate asset based securities 1,496 — 1,496 — Total $ 118,482 $ — $ 118,482 $ — September 30, 2017 Investment securities: U.S. government agency obligations $ 18,041 $ — $ 18,041 $ — Obligations of states and political subdivisions 35,795 — 35,795 — Mortgage-backed securities 36,474 — 36,474 — Agency securities 230 — 230 — Corporate debt securities 5,343 — 5,343 — Total $ 95,883 $ — $ 95,883 $ — The following table presents additional information about the security available for sale measured at fair value on a recurring basis and for which the Company utilized significant unobservable inputs (Level 3 inputs) to determine fair value for the transition period ended December 31, 2018 and the years ended September 30, 2018 and 2017 : Fair value measurements using significant unobservable inputs (Level 3) Transition period ended December 31, Years ended September 30, Securities available for sale 2018 2018 2017 Balance, beginning of year $ — $ — $ 376 Payments received — — (500 ) Total gains or losses (realized/unrealized) Included in earnings — — 124 Included in other comprehensive income — — — Transfers in and/or out of Level 3 — — — Balance, end of year $ — $ — $ — There were no transfers in or out of Level 1, Level 2 or Level 3 fair value measurements during the transition period ended December 31, 2018 and the years ended September 30, 2018 and 2017 . There were no losses included in earnings attributable to the change in unrealized gains or losses relating to the available-for-sale securities above with fair value measurements utilizing significant unobservable inputs for the transition period ended December 31, 2018 and the years ended September 30, 2018 and 2017 , respectively. The Level 3 security in the table above, consisted of one private placement collateralized debt obligation security, backed by trust preferred securities. The market for the trust preferred security was not active, and markets for similar securities were equally inactive. The new issue market was also inactive and there were very few market participants willing or able to transact for these trust preferred securities. In June 2017, this trust preferred security was called. Assets Measured on a Nonrecurring Basis The following tables present the financial instruments measured at fair value on a nonrecurring basis as of December 31, 2018 , September 30, 2018 and September 30, 2017 : Fair Value Quoted Prices in Active Markets for Identical Instruments (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2018 Foreclosed and repossessed assets, net $ 2,570 $ — $ — $ 2,570 Impaired loans with allocated allowances 2,485 — — 2,485 Mortgage servicing rights 5,214 — — 5,214 Total $ 10,269 $ — $ — $ 10,269 September 30, 2018 Foreclosed and repossessed assets, net $ 2,768 $ — $ — $ 2,768 Impaired loans with allocated allowances 2,168 — — 2,168 Mortgage servicing rights 2,669 — — 2,669 Total $ 7,605 $ — $ — $ 7,605 September 30, 2017 Foreclosed and repossessed assets, net $ 6,017 $ — $ — $ 6,017 Impaired loans with allocated allowances 1,490 — — 1,490 Mortgage servicing rights 1,951 — — 1,951 Total $ 9,458 $ — $ — $ 9,458 The fair value of impaired loans referenced above was determined by obtaining independent third party appraisals and/or internally developed collateral valuations to support the Company’s estimates and judgments in determining the fair value of the underlying collateral supporting impaired loans. The fair value of foreclosed and repossessed assets referenced above was determined by obtaining market price valuations from independent third parties wherever such quotes were available for other collateral owned. The Company utilized independent third party appraisals to support the Company’s estimates and judgments in determining fair value for other real estate owned. The fair value of mortgage servicing rights referenced above was determined based on a third party discounted cash flow analysis utilizing both observable and unobservable inputs. The following table represents additional quantitative information about assets measured at fair value on a recurring and nonrecurring basis and for which we have utilized Level 3 inputs to determine their fair value at December 31, 2018 , September 30, 2018 and September 30, 2017. Fair Value Valuation Techniques (1) Significant Unobservable Inputs (2) Range December 31, 2018 Foreclosed and repossessed assets, net $ 2,570 Appraisal value Estimated costs to sell 10 - 15% Impaired loans with allocated allowances $ 2,485 Appraisal value Estimated costs to sell 10 - 15% Mortgage servicing rights $ 5,214 Discounted cash flows Discounted rates 9.5% - 12.5% September 30, 2018 Foreclosed and repossessed assets, net $ 2,768 Appraisal value Estimated costs to sell 10 - 15% Impaired loans with allocated allowances $ 2,168 Appraisal value Estimated costs to sell 10 - 15% Mortgage servicing rights $ 2,669 Discounted cash flows Discounted rates 9.5% - 12.5% September 30, 2017 Foreclosed and repossessed assets, net $ 6,017 Appraisal value Estimated costs to sell 10 - 15% Impaired loans with allocated allowances $ 1,490 Appraisal value Estimated costs to sell 10 - 15% Mortgage servicing rights $ 1,951 Discounted cash flows Discounted rates 9.5% - 12.5% (1) Fair value is generally determined through independent third-party appraisals of the underlying collateral, which generally includes various level 3 inputs which are not observable. (2) The fair value basis of impaired loans and real estate owned may be adjusted to reflect management estimates of disposal costs including, but not limited to, real estate brokerage commissions, legal fees, and delinquent property taxes. Fair Values of Financial Instruments ASC 825-10 and ASC 270-10, Interim Disclosures about Fair Value Financial Instruments , require disclosures about fair value financial instruments and significant assumptions used to estimate fair value. The estimated fair values of financial instruments not previously disclosed are determined as follows: Cash and Cash Equivalents (carried at cost) Due to their short-term nature, the carrying amounts of cash and cash equivalents are considered to be a reasonable estimate of fair value and represents a level 1 measurement. Other Interest Bearing Deposits Fair value of interest bearing deposits is estimated using a discounted cash flow analysis based on current interest rates being offered by instruments with similar terms and represents a level 2 measurement. Non-marketable Equity Securities, (carried at cost) Non-marketable equity securities are comprised of Federal Home Loan Bank stock and Federal Reserve Bank stock carried at cost, which are their redeemable fair value since the market for each category of this stock is restricted and represents a level 1 measurement. Loans Receivable, net Fair value is estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as real estate, C&I and consumer. The fair value of loans is calculated by discounting scheduled cash flows through the estimated maturity date using market discount rates reflecting the credit and interest rate risk inherent in the loan, including estimates of prepayments and reasonable prepayment rates. The estimate of maturity is based on the Bank’s repayment schedules for each loan classification. The fair value of variable rate loans approximates carrying value. The net carrying value of the loans acquired through the CBN, WFC and United Bank acquisitions approximates the fair value of the loans at December 31, 2018 . The fair value of loans is considered to be a level 3 measurement. Loans Held for Sale Fair values are based on quoted market prices of similar loans sold on the secondary market. Mortgage Servicing Rights Fair values are estimated using discounted cash flows based on current market rates and conditions. Impaired Loans (carried at fair value) Impaired loans are loans in which the Company has measured impairment, generally based on the fair value of the loan’s collateral. Fair value is generally determined based upon independent third-party appraisals of the properties, or discounted cash flows based upon the expected proceeds. These assets are included as Level 3 fair values, based upon the lowest level of input that is significant to the fair value measurements. Foreclosed Assets (carried at fair value) Foreclosed assets are the only non-financial assets valued on a non-recurring basis which are held by the Company at fair value, less cost to sell. At foreclosure or repossession, if the fair value, less estimated costs to sell, of the collateral acquired (real estate, vehicles, equipment) is less than the Company’s recorded investment in the related loan, a write-down is recognized through a charge to the ALL. Additionally, valuations are periodically performed by management and any subsequent reduction in value is recognized by a charge to income. The fair value of foreclosed assets held-for-sale is estimated using Level 3 inputs based on observable market data. Accrued Interest Receivable and Payable Due to their short-term nature, the carrying amounts of accrued interest receivable and payable are considered to be a reasonable estimate of fair value and represents a level 1 measurement. Deposits The fair value of deposits with no stated maturity, such as demand deposits, savings accounts, and money market accounts, is the amount payable on demand at the reporting date. The fair value of fixed rate certificate accounts is calculated by using discounted cash flows applying interest rates currently being offered on similar certificates and represents a level 3 measurement. The net carrying value of fixed rate certificate accounts acquired through the United Bank acquisition approximates the fair value of the certificates at December 31, 2018 and represents a level 3 measurement. Federal Home Loan Bank ("FHLB") Advances The fair value of long-term borrowed funds is estimated using discounted cash flows based on the Bank’s current incremental borrowing rates for similar borrowing arrangements. The carrying value of short-term borrowed funds approximates their fair value and represents a level 2 measurement. Off-Balance-Sheet Instruments The fair value of off-balance sheet commitments would be estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements, the current interest rates, and the present creditworthiness of the customers. Since this amount is immaterial to the Company’s consolidated financial statements, no amount for fair value is presented. The table below represents what we would receive to sell an asset or what we would have to pay to transfer a liability in an orderly transaction between market participants at the measurement date. The carrying amount and estimated fair value of the Company's financial instruments as of the dates indicated below were as follows: December 31, 2018 September 30, 2018 September 30, 2017 Valuation Method Used Carrying Amount Estimated Fair Value Carrying Amount Estimated Fair Value Carrying Amount Estimated Fair Value Financial assets: Cash and cash equivalents (Level I) $ 45,778 $ 45,778 $ 34,494 $ 34,494 $ 41,677 $ 41,677 Other interest-bearing deposits (Level II) 7,460 6,704 7,180 5,695 8,148 8,143 Securities available for sale "AFS" See above 146,725 146,725 118,482 118,482 95,883 95,883 Securities held to maturity "HTM" (Level II) 4,850 4,872 4,619 4,609 5,453 5,605 Non-marketable equity securities, at cost (Level I) 11,261 11,261 7,218 7,218 7,292 7,292 Loans receivable, net (Level III) 984,952 988,072 752,499 746,463 727,053 737,119 Loans held for sale (Level II) 1,927 1,927 1,917 1,917 2,334 2,334 Mortgage servicing rights (Level III) 4,486 5,214 1,840 2,669 1,886 1,951 Accrued interest receivable (Level I) 4,307 4,307 3,600 3,600 3,291 3,291 Financial liabilities: Deposits (Level III) $ 1,007,512 $ 1,005,488 $ 746,529 $ 751,548 $ 742,504 $ 746,025 FHLB advances (Level II) 109,813 109,665 63,000 63,009 90,000 89,998 Other borrowings (Level I) 24,647 24,647 24,619 24,619 30,319 30,319 Other liabilities (Level I) 7,659 7,659 5,079 5,079 4,131 4,131 Accrued interest payable (Level I) 406 406 335 335 227 227

Nature of Business and Summar_2

Nature of Business and Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation – The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Citizens Community Federal N.A. All significant inter-company accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates— Preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Estimates are used in accounting for, among other items, fair value of financial instruments, the allowance for loan losses, mortgage servicing rights, foreclosed and repossessed assets, valuation of acquired intangible assets, useful lives for depreciation and amortization, indefinite-lived intangible assets. valuation of goodwill and long-lived assets, stock based compensation, deferred tax assets, uncertain income tax positions and contingencies. Management does not anticipate any material changes to estimates made herein in the near term. Factors that may cause sensitivity to the aforementioned estimates include but are not limited to: those items described under the caption “Risk Factors” in Item 1A of the accompanying transition report on Form 10-K for the year ended December 31, 2018 and external market factors such as market interest rates and employment rates, changes to operating policies and procedures, and changes in applicable banking regulations. Actual results may ultimately differ from estimates, although management does not generally believe such differences would materially affect the consolidated financial statements in any individual reporting period.
Cash and Cash Equivalents	Cash and Cash Equivalents— For purposes of reporting cash flows in the consolidated financial statements, cash and cash equivalents include cash, due from banks, and interest bearing deposits with original maturities of three months or less .
Investment Securities; Held to Maturity and Available for Sale	Investment Securities; Held to Maturity and Available for Sale – Management determines the appropriate classification of investment securities at the time of purchase and reevaluates such designation as of the date of each balance sheet. Securities are classified as held to maturity when the Company has the positive intent and ability to hold the securities to maturity. Held to maturity securities are stated at amortized cost. Investment securities not classified as held to maturity are classified as available for sale. Available for sale securities are stated at fair value, with unrealized holding gains and losses being reported in other comprehensive income (loss), net of tax. Unrealized losses deemed other-than-temporary due to credit issues are reported in the Company’s net income in the period in which the losses arise. Interest income includes amortization of purchase premium or accretion of purchase discount. Amortization of premiums and accretion of discounts are recognized in interest income using the interest method over the estimated lives of the securities. The Company evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. As part of such monitoring, the credit quality of individual securities and their issuer is assessed. Significant inputs used to measure the amount of other-than-temporary impairment related to credit loss include, but are not limited to; the Company's intent and ability to sell the debt security prior to recovery, that it is more likely than not that the Company will not sell the security prior to recovery, default and delinquency rates of the underlying collateral, remaining credit support, and historical loss severities. Adjustments to market value of available for sale securities that are considered temporary are recorded in other comprehensive income or loss as separate components of stockholders' equity, net of tax. If the unrealized loss of a security is identified as other-than-temporary based on information available, such as the decline in the creditworthiness of the issuer, external market ratings, or the anticipated or realized elimination of associated dividends, such impairments are further analyzed to determine if credit loss exists. If there is a credit loss, it will be recorded in the Company's consolidated statement of operations. Non-credit components of the unrealized losses on available for sale securities will continue to be recognized in other comprehensive income (loss), net of tax.
Loans	Loans – Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of unearned interest, and net of deferred loan fees and costs, and non-accretable discount on purchased of credit impaired loans. Interest income is accrued on the unpaid principal balance of these loans. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the interest method without anticipating prepayments. Late charge fees are recognized into income when collected. Interest income on commercial, mortgage and consumer loans is discontinued according to the following schedules: • Commercial/agricultural real estate loans past due 90 days or more; • Commercial/agricultural non-real estate loans past due 90 days or more; • Closed ended consumer non-real estate loans past due 120 days or more; and • Residential real estate loans and open ended consumer non-real estate loans past due 180 days or more. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual status or charged off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not received for a loan placed on nonaccrual status is reversed against interest income. Interest received on such loans is accounted for on the cash basis or cost recovery method until qualifying for return to accrual status. Loans are returned to accrual status when payments are made that bring the loan account current with the contractual term of the loan and a six month payment history has been established. Interest on impaired loans considered troubled debt restructurings (“TDRs”) or substandard, less than 90 days delinquent, is recognized as income as it accrues based on the revised terms of the loan over an established period of continued payment. Substandard loans, as defined by the OCC, our primary banking regulator, are loans that are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Residential real estate loans and open ended consumer non-real estate loans are charged off to estimated net realizable value less estimated selling costs at the earlier of when (a) the loan is deemed by management to be uncollectible, or (b) the loan becomes past due 180 days or more. Closed ended consumer non-real estate loans are charged off to net realizable value at the earlier of when (a) the loan is deemed by management to be uncollectible, or (b) the loan becomes past due 120 days or more. Commercial/agricultural real estate and non-real estate loans are charged off to net realizable value at the earlier of when (a) the loan is deemed by management to be uncollectible, or (b) the loan becomes past due 90 days or more.
Allowance for Loan Losses	Allowance for Loan Losses – The allowance for loan losses (“ALL”) is a valuation allowance for probable and inherent credit losses in our loan portfolio. Loan losses are charged against the ALL when management believes that the collectability of a loan balance is unlikely. Subsequent recoveries, if any, are credited to the ALL. Management estimates the required ALL balance taking into account the following factors: past loan loss experience; the nature, volume and composition of our loan portfolio; known and inherent risks in our portfolio; information about specific borrowers’ ability to repay; estimated collateral values; current economic conditions; and other relevant factors determined by management. The ALL consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers non-impaired loans and is based on historical loss experience adjusted for certain qualitative factors. The entire ALL balance is available for any loan that, in management’s judgment, should be charged off. A loan is impaired when full payment under the loan terms is not expected. Impaired loans consist of all TDRs, as well as individual loans not considered a TDR, that are either (1) rated substandard or worse, (2) on nonaccrual status or (3) PCI loans which are impaired at the time of acquisition. All TDRs are individually evaluated for impairment. See Note 4, “Loans, Allowance for Loan Losses and Impaired Loans” for more information on what we consider to be a TDR. For TDR's or substandard loans deemed to be impaired, a specific ALL allocation may be established so that the loan is reported, net, at the lower of (a) its outstanding principal balance; (b) the present value of the loan's estimated future cash flows using the loan’s existing rate; or (c) at the fair value of any loan collateral, less estimated disposal costs, if repayment is expected solely from the underlying collateral of the loan. For TDRs less than 90+ days past due, and certain substandard loans that are less than 90+ days delinquent, the likelihood of the loan migrating to over 90 days past due is also taken into account when determining the specific ALL allocation for these particular loans. Large groups of smaller balance homogeneous loans, such as non-TDR commercial, consumer and residential real estate loans, are collectively evaluated for ALL purposes, and accordingly, are not separately identified for ALL disclosures.
Acquired Loans	Acquired Loans— Loans acquired in connection with acquisitions are recorded at their acquisition-date fair value with no carryover of related allowance for credit losses. Any allowance for loan loss on these pools reflect only losses incurred after the acquisition (meaning the present value of all cash flows expected at acquisition that ultimately are not to be received). Determining the fair value of the acquired loans involves estimating the principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. Management considers a number of factors in evaluating the acquisition-date fair value including the remaining life of the acquired loans, delinquency status, estimated prepayments, payment options and other loan features, internal risk grade, estimated value of the underlying collateral and interest rate environment. Acquired loans that met the criteria for nonaccrual of interest prior to the acquisition may be considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if we can reasonably estimate the timing and amount of the expected cash flows on such loans and if we expect to fully collect the new carrying value of the loans. As such, we may no longer consider the loan to be nonaccrual or nonperforming and may accrue interest on these loans, including the impact of any accretable yield. Loans acquired with deteriorated credit quality are accounted for in accordance with Accounting Standards Codification (“ASC”) 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (ASC 310-30) if, at acquisition, the loans have evidence of credit quality deterioration since origination and it is probable that all contractually required payments will not be collected. At acquisition, the Company considers several factors as indicators that an acquired loan has evidence of deterioration in credit quality. These factors include; loans 90 days or more past due, loans with an internal risk grade of substandard or below, loans classified as non-accrual by the acquired institution, and loans that have been previously modified in a troubled debt restructuring. Under the ASC 310-30 model, the excess of cash flows expected to be collected at acquisition over recorded fair value is referred to as the accretable yield and is the interest component of expected cash flow. The accretable yield is recognized into income over the remaining life of the loan if the timing and/or amount of cash flows expected to be collected can be reasonably estimated (the accretion method). If the timing or amount of cash flows expected to be collected cannot be reasonably estimated, the cost recovery method of income recognition is used. The difference between the loan’s total scheduled principal and interest payments over all cash flows expected to be collected at acquisition, considering the impact of prepayments, is referred to as the non-accretable difference. The non-accretable difference represents contractually required principal and interest payments which the Company does not expect to collect. Over the life of the loan, management continues to estimate cash flows expected to be collected. Decreases in expected cash flows are recognized as impairments through a charge to the provision for loan losses resulting in an increase in the allowance for loan losses. Subsequent improvements in cash flows result in first, reversal of existing valuation allowances recognized subsequent to acquisition, if any, and next, an increase in the amount of accretable yield to be subsequently recognized in interest income on a prospective basis over the loan’s remaining life. Acquired loans that were not individually determined to be purchased with deteriorated credit quality are accounted for in accordance with ASC 310-20, Nonrefundable Fees and Other Costs (ASC 310-20), whereby the premium or discount derived from the fair market value adjustment, on a loan-by-loan or pooled basis, is recognized into interest income on a level yield basis over the remaining expected life of the loan or pool. For all acquired loans, the outstanding loan balances less any related accretable yield and/or non-accretable difference is referred to as the loans' carrying amount.
Loans Held for Sale	Loans Held for Sale — Loans held for sale are those loans the Company has the intent to sell in the foreseeable future. They are carried at the lower of aggregate cost or fair value. Gains and losses on sales of loans are recognized at settlement dates, and are determined by the difference between the sales proceeds and the carrying value of the loans after allocating costs to servicing rights retained. All sales are made without recourse. Interest rate lock commitments on mortgage loans to be funded and sold are valued at fair value, and are included in other assets or liabilities, if material.
Mortgage Servicing Rights	Mortgage Servicing Rights— Mortgage servicing rights ("MSR") assets result as the Company sells loans to investors in the secondary market and retains the rights to service mortgage loans sold to others. MSR assets are initially measured at fair value; assessed at least annually for impairment; carried at the lower of the initial capitalized amount, net of accumulated amortization, or estimated fair value. MSR assets are amortized in proportion to and over the period of estimated net servicing income, with the amortization recorded in non-interest expense in the consolidated statement of operations. The valuation of MSRs and related amortization thereon are based on numerous factors, assumptions and judgments, such as those for: changes in the mix of loans, interest rates, prepayment speeds, and default rates. Changes in these factors, assumptions and judgments may have a material effect on the valuation and amortization of MSRs. Although management believes that the assumptions used to evaluate the MSRs for impairment are reasonable, future adjustment may be necessary if future economic conditions differ substantially from the economic assumptions used to determine the value of MSRs.
Non-marketable Equity Securities	Non-marketable Equity Securities — Non-marketable equity securities are comprised of Federal Home Loan Bank (FHLB) stock and Federal Reserve Bank (FRB) stock, and are carried at cost. The Bank is a member of the FHLB system. Members are required to own a certain amount of FHLB stock based on the Bank’s level of borrowings from the FHLB and other factors, and may invest in additional amounts of FHLB stock. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on the ultimate recovery of par value. The determination of whether a decline affects the ultimate recovery is influenced by criteria such as: (1) the significance of the decline in net assets of the FHLB as compared to the capital stock amount and length of time a decline has persisted; (2) the impact of legislative and regulatory changes on the FHLB; and (3) the liquidity position of the FHLB. Cash dividends are reported as income. FHLB stock is evaluated quarterly for impairment. Quarterly cash dividends are paid on FHLB stock owned by members as a condition for required membership and also paid on stock owned by members based on activity. Based on management’s quarterly evaluation, no impairment has been recorded on these securities. As a National Banking Association, the Bank must be a member of the Federal Reserve system. Each member bank is required to subscribe to Federal Reserve Stock in an amount equal to 6 percent of its capital and surplus. Although the par value of the stock is $100 per share, banks (including the Bank) pay only $50 per share at the time of purchase, with the understanding that the other half of the subscription amount is subject to call at any time. Dividends are paid at the statutory rate of 6 percent per annum, or $1.50 per share semi-annually on the last business day of June and December.
Foreclosed and Repossessed Assets, net	Foreclosed and Repossessed Assets, net – Assets acquired through foreclosure or repossession are initially recorded at fair value, less estimated costs to sell, which establishes a new cost basis. If the fair value declines subsequent to foreclosure or repossession, a write-down is recorded through expense. Costs incurred after acquisition are expensed and are included in non-interest expense, other in the Consolidated Statements of Operations.
Transfers of Financial Assets	Transfers of financial assets— Transfers of financial assets 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 entity, (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 entity does not maintain effective control over the transferred assets through an agreement to repurchase them before maturity.
Goodwill	Goodwill and other intangible assets— The Company accounts for goodwill and other intangible assets in accordance with ASC Topic 350, "Intangibles - Goodwill and Other." The Company records the excess of the cost of acquired entities over the fair value of identifiable tangible and intangible assets acquired, less liabilities assumed, as goodwill. The Company amortizes acquired intangible assets with definite useful economic lives over their useful economic lives utilizing the straight-line method. On a periodic basis, management assesses whether events or changes in circumstances indicate that the carrying amounts of the intangible assets may be impaired. The Company does not amortize goodwill and any acquired intangible asset with an indefinite useful economic life, but reviews them for impairment at a reporting unit level on an annual basis, or when events or changes in circumstances indicate that the carrying amounts may be impaired. A reporting unit is defined as any distinct, separately identifiable component of the Company’s one operating segment for which complete, discrete financial information is available and reviewed regularly by the segment’s management. The Company has one reporting unit as of December 31, 2018 which is related to its banking activities. The Company has performed the required goodwill impairment test and has determined that goodwill was not impaired as of December 31, 2018 .
Office Properties and Equipment	Office Properties and Equipment— Premises and equipment are stated at cost less accumulated depreciation. Land is carried at cost. Maintenance and repair costs are charged to expense as incurred. Gains or losses on disposition of office properties and equipment are reflected in income. Buildings and related components are depreciated using the straight-line method with useful lives ranging from 10 to 40 years. Furniture, fixtures and equipment are depreciated using the straight-line (or accelerated) method with useful lives ranging from 3 to 10 years. Leasehold improvements are depreciated using the straight-line (or accelerated) method with useful lives based on the lesser of (a) the estimated life of the lease, or (b) the estimated useful life of the leasehold improvement.
Interest Bearing Deposits	Interest Bearing Deposits— Other interest bearing deposits are certificate of deposit investments made by the Bank with other financial institutions that are carried at cost. The weighted average months to maturity of the interest bearing deposits is 19.91 months . Balances over $250 in those institutions are not insured by the FDIC and therefore pose a potential risk in the event the institution were to fail.
Debt issuance costs	Debt and equity issuance costs— Debt issuance costs, which consist primarily of fees paid to note lenders, are deferred and included in other borrowings in the consolidated balance sheet. Debt issuance costs are amortized over the contractual term of the corresponding debt, as a component of interest expense on other borrowed funds in the consolidated statement of operations. Specific costs associated with the issuance of shares of the Company's common or preferred stock are netted against proceeds and recorded in stockholders' equity, as additional paid in capital, on the consolidated balance sheet, in the period of the share issuance.
Advertising Costs, Marketing and Public Relations Expense	Advertising, Marketing and Public Relations Expense— The Company expenses all advertising, marketing and public relations costs as they are incurred.
Income Taxes	Income Taxes – The Company accounts for income taxes in accordance with the Financial Accounting Standards Board (FASB) Accounting Standards Codification (“ASC”) Topic 740, “Income Taxes.” Under this guidance, deferred taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates that will apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date. See Note 14, "Income Taxes" for details on the Company’s income taxes. The Tax Cuts and Jobs Act of 2017 ("Tax Act"), enacted on December 22, 2017, reduces corporate Federal income tax rates for the Company from 34% to 24.5% for fiscal 2018, and 21% for periods after September 30, 2018. GAAP requires the impact of the provisions of the Tax Act be accounted for in the period of enactment. At December 31, 2017, we had not completed our accounting for the tax effects of enactment of the Tax Act; however, in certain cases, as described below, we made a reasonable estimate and continue to account for those items based on our existing accounting under ASC 740, Income Taxes, and the provisions of the tax laws that were in effect immediately prior to enactment. The Company revalued its net deferred tax assets to account for the future impact of lower corporate taxes. For the items for which we were able to determine a reasonable estimate, we recorded an increased provisional amount of income tax expense of $275 in December 2017, related to the revaluation of the deferred tax assets to both the revaluation of timing differences and the unrealized loss on securities. In the fourth quarter of fiscal 2018, based on updated information obtained in connection with the filing of our tax return and analysis of our net deferred tax asset both from the return and 2018 tax provisions, we finalized the tax analysis and recorded an additional $63 of expense, or a net increase in our tax provision for the year of $338 related to the Tax Act. The Company regularly reviews the carrying amount of its net deferred tax assets to determine if the establishment of a valuation allowance is necessary. If based on the available evidence, it is more likely than not that all or a portion of the Company’s net deferred tax assets will not be realized in future periods, a deferred tax valuation allowance would be established. Consideration is given to various positive and negative factors that could affect the realization of the deferred tax assets. In evaluating this available evidence, management considers, among other things, historical performance, expectations of future earnings, the ability to carry back losses to recoup taxes previously paid, the length of statutory carry forward periods, any experience with utilization of operating loss and tax credit carry forwards not expiring, tax planning strategies and timing of reversals of temporary differences. Significant judgment is required in assessing future earnings trends and the timing of reversals of temporary differences. Accordingly, the Company’s evaluation is based on current tax laws as well as management’s expectations of future performance.
Revenue Recognition	Revenue Recognition - The Company recognizes revenue in the consolidated statements of operations as it is earned and when collectability is reasonably assured. The primary source of revenue is interest income from interest earning assets, which is recognized on the accrual basis of accounting using the effective interest method. The recognition of revenues from interest earning assets is based upon formulas from underlying loan agreements, securities contracts or other similar contracts. Non-interest income is recognized on the accrual basis of accounting as services are provided or as transactions occur. Non-interest income includes fees from brokerage and advisory service, deposit accounts, merchant services, ATM and debit card fees, mortgage banking activities, and other miscellaneous services and transactions. Commission revenue is recognized as of the effective date of the insurance policy or the date the customer is billed, whichever is later. The Company also receives contingent commissions from insurance companies which are based on the overall profitability of their relationship based primarily on the loss experience of the insurance placed by the Company. Contingent commissions from insurance companies are recognized when determinable. Commission revenue is included in other non-interest income in the consolidated statement of operations.
Earnings Per Share	Earnings Per Share – Basic earnings per common share is net income or loss divided by the weighted average number of common shares outstanding during the period. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable during the period, consisting of stock options outstanding under the Company’s stock incentive plans that have an exercise price that is less than the Company's stock price on the reporting date.
Loss Contingencies	Loss Contingencies— Loss contingencies, including claims and legal actions arising in the normal course of business, are recorded as liabilities when the likelihood of loss is probable and an amount of loss can be reasonably estimated.
Off-Balance-Sheet Financial Instruments	Off-Balance-Sheet Financial Instruments— In the ordinary course of business, the Bank has entered into off-balance sheet financial instruments consisting of commitments to extend credit and commitments under lines of credit arrangements, issued to meet customer financial needs. Such financial instruments are recorded in the financial statements when they become payable. See Note 11, "Commitments and Contingencies" in Notes to Consolidated Financial Statements.
Derivatives--Rate-lock Commitments and Forward Sale Agreements	Derivatives--Rate-lock Commitments and Forward Sale Agreements — The Company enters into commitments to originate loans, whereby the interest rate on the loan is determined prior to funding (rate-lock commitment). Rate-lock commitments on mortgage loans held for sale are derivative instruments. Derivative instruments are carried on the consolidated balance sheets at fair value, and changes in the fair value thereof are recognized in the consolidated statements of income. The Company originates single-family residential loans for sale, pursuant to programs primarily with the Federal Home Loan Mortgage Corporation (FHLMC) and other similar third parties. In connection with these programs, at the time the Company initially issues a loan commitment, it does not lock in a specific interest rate. At the time the interest rate is locked in by the borrower, the Company concurrently enters into a forward loan sale agreement with the prospective loan purchaser, at a specific price, in order to manage the interest rate risk inherent to the rate-lock commitment. The forward sale agreement also meets the definition of a derivative instrument. Any change in the fair value of the loan commitment after the borrower locks in the interest rate is substantially offset by the corresponding change in the fair value of the forward loan sale agreement related to such loan. The period from the time the borrower locks in the interest rate, to the time the Company funds the loan and sells the loan to a third party, is generally, approximately 45 days. The fair value of each instrument will rise and fall in response to changes in market interest rates, subsequent to the dates the interest rate locks and forward sale agreements are entered into. In the event that interest rates rise after the Company enters into an interest rate lock, the fair value of the loan commitment will decline. However, the fair value of the forward loan sale agreement related to such loan commitment should increase by substantially the same amount, effectively eliminating the Company's interest rate and price risks.
Other Comprehensive Income	Other Comprehensive Income — Accumulated and other comprehensive income or loss is comprised of the unrealized and realized gains and losses on securities available for sale and pension liability adjustments, net of tax, and is shown on the accompanying Consolidated Statements of Other Comprehensive Income.
Operating Segments	Operating Segments— While our executive officers monitor the revenue streams of the various banking products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Accordingly, all of the Company’s banking operations are considered by management to be aggregated in one reportable operating segment.
Bank Owned Life Insurance	Bank Owned Life Insurance (BOLI)— The Bank invests in bank-owned life insurance (BOLI) as a source of funding for employee benefit expenses. BOLI involves the purchasing of life insurance by the Bank on a select group of employees. The Bank is the owner and beneficiary of the policies. Income from the increase in cash surrender value of the policies as well as the receipt of death benefits is included in non-interest income on the consolidated statement of income
Reclassifications	Reclassifications— Certain items previously reported were reclassified for consistency with the current presentation.
Recent Accounting Standards	Recent Accounting Pronouncements—Adopted ASU 2018-02; Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income— Issued in February 2018, the ASU permits, but does not require, entities to reclassify tax effects stranded in accumulated other comprehensive income resulting from the Tax Cuts and Jobs Act of 2017 to retained earnings. Companies that elect to reclassify these amounts must reclassify stranded tax effects for all items accounted for in accumulated other comprehensive income. The Company elected early adoption and adopted this standard update, effective January 1, 2018. The Company’s stranded tax effects were related to valuation of the net deferred tax asset attributable to items of accumulated other comprehensive income (loss), which are unrealized gains (losses) on available-for-sale securities. Adoption resulted in a reclassification between two categories of stockholders’ equity at March 31, 2018, with an increase of $137 in retained earnings and a decrease in accumulated other comprehensive loss for the same amount (no net change in stockholders’ equity). Recently Issued, But Not Yet Effective Accounting Pronouncements ASU 2014-09; Revenue from Contracts with Customers (Topic 606)— Under the ASU, as modified by subsequent ASUs, revenue is recognized when a customer obtains control of promised services in an amount that reflects the consideration the entity expects to receive in exchange for those services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company applied the five-step method outlined in the ASU to all revenue streams scoped-in by the ASU and elected the modified retrospective implementation method. Substantially all of the Company’s interest income and certain noninterest income were not impacted by the adoption of this ASU because the revenue from those contracts with customers is covered by other guidance in U.S. GAAP. The Company’s largest sources of noninterest revenue which are subject to the guidance include fees and service charges on loan and deposit accounts and interchange revenue from debit card transactions. ASU 2014-08, as amended, will become effective for the Company’s annual and interim periods beginning in the first quarter 2019. Adoption of ASU 2014-09 is not expected to have a material impact on the Company’s consolidated financial statements as the change in the timing and pattern of the Company’s revenue recognition related to scoped-in noninterest income recognized under the newly issued ASU is expected to be consistent with the current applicable accounting guidance. The Company expects that upon adoption of this ASU any additional disclosures related to non-interest income will be added to the consolidated financial statements. ASU 2016-01; Recognition and Measurement of Financial Assets and Liabilities— The guidance affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. ASU 2016-01 will be effective for the Company in the first quarter of 2019. Adoption of ASU 2016-01 is not expected to have a material impact on the Company’s consolidated financial statements. ASU 2016-02; Leases (Topic 842)— The ASU changes current GAAP by requiring that lease assets and liabilities arising from operating leases be recognized on the balance sheet. In July 2018, the FASB issued ASU 2018-10 and ASU 2018-11, Codification Improvements to Topic 842, Leases, amending various aspects of Topic 842. Topic 842 would not significantly change the recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee from current U.S. GAAP. For leases with a term of 12 months or less, a lessee would be permitted to make an accounting policy election, by class of underlying asset, not to recognize lease assets and liabilities. Topic 842 will become effective for the Company for annual and interim periods beginning in the first quarter 2019. Adoption of Topic 842 is not expected to have a material impact on the Company’s consolidated financial statements. However, the resulting increase in both total assets and total liabilities will impact the Bank and Company’s regulatory capital and related ratios. Management's preliminary estimate of the initial increase on total assets and total liabilities resulting from adoption is approximately $5,000 . The Company leases certain branch locations and its corporate offices under operating leases that will result in the recognition of lease assets and lease liabilities on the consolidated balance sheet under Topic 842. Eleven of the Company’s locations are leased. ASU 2016-13; Financial Instruments-Credit Losses (Topic 326)— The ASU changes accounting for credit losses on loans receivable and debt securities from an incurred loss methodology to an expected credit loss methodology. Among other things, ASU 2016-13 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. Accordingly, ASU 2016-13 requires the use of forward-looking information to form credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, though the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, ASU 2016-13 amends the accounting for credit losses on debt securities and purchased financial assets with credit deterioration. The amendments in ASU 2016-13 will be effective for the Company beginning in the first quarter 2020. Earlier adoption is permitted; however, the Company does not currently plan to adopt the ASU early. Management is assessing alternative loss estimation methodologies and the Company’s data and system needs in order to evaluate the impact that adoption of this standard will have on the Company’s financial condition and results of operations. The Company will record the effect of implementing this ASU through a cumulative-effect adjustment through retained earnings as of the beginning of the reporting period in which the ASU is effective, which will be March 31, 2020. ASU 2017-04; Intangibles - Goodwill and Other (Topic 350)— The ASU simplifies the accounting for goodwill impairment. This guidance, among other things, removes step two of the goodwill impairment test thus eliminating the need to determine the fair value of individual assets and liabilities of the reporting unit. Upon adoption of this ASU, goodwill impairment will be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This may result in either greater or less impairment being recognized than under current guidance. This Update will become effective for the Company’s annual goodwill impairment tests beginning in the first quarter 2020. The Company does not expect adoption of this ASU to have a material impact on its consolidated financial statements. ASU 2018-13, Fair Value Measurement (Topic 820)— The ASU modifies disclosure requirements on fair value measurements. This ASU removes requirements to disclose, (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, and (2) the policy for timing of transfers between levels and the valuation processes for Level 3 fair value measurements. ASU 2018-13 clarifies that, disclosure regarding measurement uncertainty, is intended to communicate information about the uncertainty in measurement, as of the reporting date. ASU 2018-13 adds certain disclosure requirements, including (1) disclosure of changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements, and (2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this ASU are effective for the Company beginning in the first quarter 2020. The amendments on (1) changes in unrealized gains and losses, (2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and (3) the narrative description of measurement uncertainty, should be applied prospectively. All other amendments should be applied retrospectively for all periods presented. The Company does not expect adoption of this ASU to have a material impact on its consolidated financial position or results of operations. ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)— The ASU was issued to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (hosting arrangement), by providing guidance for determining when the arrangement includes a software license. The amendments align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract, with similar costs to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments. This guidance will become effective for the Company beginning in the first quarter 2020, with early adoption permitted. The Company does not expect adoption of this ASU to have a material impact on its consolidated financial statements.
