Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation The accompanying consolidated financial statements include the accounts of Timberland Bancorp, Inc. (“Timberland Bancorp”); its wholly owned subsidiary, Timberland Bank (the “Bank”); and the Bank’s wholly owned subsidiary, Timberland Service Corp. (collectively, the "Company”). All significant intercompany transactions and balances have been eliminated in consolidation. Nature of Operations Timberland Bancorp is a bank holding company which operates primarily through its subsidiary, the Bank. The Bank was established in 1915 and, through its 22 branches located in Grays Harbor, Pierce, Thurston, Kitsap, King and Lewis counties in Washington State, attracts deposits from the general public, and uses those funds, along with other borrowings, primarily to provide residential real estate, construction, commercial real estate, commercial business and consumer loans to borrowers primarily in western Washington. Consolidated Financial Statement Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S.") (“GAAP”) and prevailing practices within the banking industry. The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities, as of the date of the consolidated balance sheets, and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the determination of OTTI in the estimated fair value of investment securities, the valuation of deferred tax assets, the valuation of MSRs, the valuation of OREO and the valuation of goodwill for potential impairment. Certain prior year amounts have been reclassified to conform to the 2016 fiscal year presentation with no change to previously reported net income or shareholders’ equity. Segment Reporting The Company has one reportable operating segment which is defined as community banking in western Washington under the operating name “Timberland Bank.” Preferred Stock Sold in Troubled Asset Relief Program ("TARP") Capital Purchase Program ("CPP") On December 23, 2008, the Company received $16.64 million from the U.S. Treasury Department ("Treasury") as a part of the Treasury's CPP, which was established as part of the TARP. The Company sold 16,641 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A ("Series A Preferred Stock"), with a liquidation value of $1,000 per share and a related warrant to purchase 370,899 shares of the Company's common stock at an exercise price of $6.73 per share (subject to anti-dilution adjustments) at any time through December 23, 2018. The proceeds received in connection with the issuance of the Series A Preferred Stock were allocated between the preferred stock and warrant based on their relative fair values on the date of issuance. As a result, the preferred stock's initial recorded value was at a discount from the liquidation value or stated value. The discount from the liquidation value was accreted to the expected/actual redemption date and charged to retained earnings. This accretion was recorded using the level-yield method. On November 13, 2012, the Company’s outstanding 16,641 shares of Series A Preferred Stock were sold by the Treasury as part of its efforts to manage and recover its investments under the TARP. While the sale of the Series A Preferred Stock to new owners did not result in any proceeds to the Company and did not change the Company’s capital position or accounting for these securities, it did eliminate restrictions put in place by the Treasury on TARP recipients. On June 12, 2013, the Treasury sold the warrant to purchase up to 370,899 shares of the Company’s common stock to private investors. The sale of the warrant to new owners did not result in any proceeds to the Company and did not change the Company's capital position or accounting for the warrant. During the year ended September 30, 2013, the Company purchased and retired 4,576 shares of its Series A Preferred Stock for $4.32 million; a $255,000 discount from its liquidation value. The discount from liquidation value on the repurchased shares was recorded as an increase to retained earnings. On December 20, 2013, the Company redeemed the remaining 12,065 shares of its Series A Preferred Stock at the liquidation value of $12.07 million. The Series A Preferred Stock paid a 5.0% dividend through December 20, 2013, the date of its redemption. Cash and Cash Equivalents and Cash Flows The Company considers amounts included in the consolidated balance sheets’ captions “Cash and due from financial institutions” and “Interest-bearing deposits in banks,” all of which mature within ninety days, to be cash equivalents for purposes of reporting cash flows. Cash flows from loans, deposits, FHLB borrowings and repurchase agreements are reported net in the accompanying consolidated statements of cash flows. Interest-bearing deposits in banks as of September 30, 2016 and 2015 included deposits with the Federal Reserve Bank of San Francisco ("FRB") of $88,420,000 and $70,975,000, respectively. The Company also maintains balances in correspondent bank accounts which, at times, may exceed FDIC insurance limits of $250,000. Management believes that its risk of loss associated with such balances is minimal due to the financial strength of the FRB and the correspondent banks. CDs Held for Investment CDs held for investment include amounts invested with other FDIC-insured financial institutions for a stated interest rate and with a fixed maturity date. Such CDs generally have a maturity of 12 to 24 months from the date of purchase by the Company. Early withdrawal penalties may apply; however, the Company intends to hold these CDs to maturity. The Company generally limits its purchases of CDs to a maximum of $250,000 (the FDIC insurance coverage limit) with any single financial institution. Investment Securities Investment securities are classified upon acquisition as either held to maturity or available for sale. Investment securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and reflected at amortized cost. Investment securities classified as available for sale are reflected at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income (loss), net of income tax effects. Premiums and discounts are amortized to earnings using the interest method over the contractual lives of the securities. Gains and losses on sales of investment securities are recognized on the trade date and determined using the specific identification method. In estimating whether there are any OTTI losses, management considers (1) the length of time and the extent to which the fair value has been less than amortized cost, (2) the financial condition and near term prospects of the issuer, (3) the impact of changes in market interest rates and (4) the intent and ability of the Company to retain its investment for a period of time sufficient to allow for any anticipated recovery in fair value. Declines in the fair value of individual investment securities available for sale that are deemed to be other than temporary are reflected in earnings when identified. The fair value of the investment security then becomes the new cost basis. For individual investment securities that are held to maturity which the Company does not intend to sell, and it is not more likely than not that the Company will be required to sell before recovery of its amortized cost basis, the other than temporary decline in the fair value of the investment security related to: (1) credit loss is recognized in earnings and (2) market or other factors is recognized in other comprehensive income (loss). Credit loss is recorded if the present value of expected future cash flows is less than the amortized cost. For individual investment securities which the Company intends to sell or more likely than not will not recover all of its amortized cost, the OTTI is recognized in earnings equal to the entire difference between the investment security’s cost basis and its fair value at the consolidated balance sheet date. For individual investment securities for which credit loss has been recognized in earnings, interest accruals and amortization and accretion of premiums and discounts are suspended when the credit loss is recognized. Interest received after accruals have been suspended is recognized on a cash basis. FHLB Stock The Bank, as a member of the FHLB, is required to maintain an investment in capital stock of the FHLB in an amount equal to 0.12% of the Bank's total assets plus 4.00% of borrowings from the FHLB. No ready market exists for this stock, and it has no quoted market value. However, redemption of FHLB stock has historically been at par value. The Company's investment in FHLB stock is carried at cost, which approximates fair value. The Company evaluates its FHLB stock for impairment as needed. The Company's determination of whether this investment is impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared with the capital stock amount and the length of time any decline has persisted; (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB; and (4) the liquidity position of the FHLB. Based on its evaluation, the Company determined that there was no impairment of FHLB stock at September 30, 2016 and 2015. Loans Held for Sale Mortgage loans and commercial business loans originated and intended for sale in the secondary market are stated in the aggregate at the lower of cost or estimated fair value. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Gains or losses on sales of loans are recognized at the time of sale. The gain or loss is the difference between the net sales proceeds and the recorded value of the loans, including any remaining unamortized deferred loan origination fees. Loans Receivable Loans are stated at the amount of unpaid principal, reduced by the undisbursed portion of construction loans in process, deferred loan origination fees and the allowance for loan losses. Interest on loans is accrued daily based on the principal amount outstanding. Generally, the accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to make payments as they become due or when they are past due 90 days as to either principal or interest (based on contractual terms), unless the loan is well secured and in the process of collection. In determining whether a borrower may be able to make payments as they become due, management considers circumstances such as the financial strength of the borrower, the estimated collateral value, reasons for the delays in payments, payment record, the amounts past due and the number of days past due. All interest accrued but not collected for loans that are placed on non-accrual status or charged off is reversed against interest income. Subsequent collections on a cash basis are applied proportionately to past due principal and interest, unless collectability of principal is in doubt, in which case all payments are applied to principal. Loans are returned to accrual status when the loan is deemed current, and the collectability of principal and interest is no longer doubtful, or, in the case of one- to four-family loans, when the loan is less than 90 days delinquent. The categories of non-accrual loans and impaired loans overlap, although they are not identical. The Company charges fees for originating loans. These fees, net of certain loan origination costs, are deferred and amortized to income on the level-yield basis over the loan term. If the loan is repaid prior to maturity, the remaining unamortized deferred loan origination fee is recognized in income at the time of repayment. Troubled Debt Restructured Loans A troubled debt restructured loan ("TDR") is a loan for which the Company, for reasons related to a borrower’s financial difficulties, grants a significant concession to the borrower that the Company would not otherwise consider. Examples of such concessions include, but are not limited to: a reduction in the stated interest rate; an extension of the maturity at an interest rate below current market rates; a reduction in the face amount of the debt; a reduction in the accrued interest; or re-amortizations, extensions, deferrals and renewals. Troubled debt restructured loans are considered impaired and are individually evaluated for impairment. Troubled debt restructured loans are classified as non-accrual (and considered to be non-performing) unless they have been performing in accordance with modified terms for a period of at least six months. Allowance for Loan Losses The allowance for loan losses is maintained at a level sufficient to provide for probable losses inherent in the loan portfolio. The allowance is provided based upon management's comprehensive analysis of the pertinent factors underlying the quality of the loan portfolio. These factors include changes in the amount and composition of the loan portfolio, delinquency levels, actual loan loss experience, current economic conditions, and a detailed analysis of individual loans for which full collectability may not be assured. The detailed analysis includes methods to estimate the fair value of loan collateral and the existence of potential alternative sources of repayment. The allowance consists of specific and general components. The specific component relates to loans that are deemed impaired. For such loans that are classified as impaired, an allowance is established when the discounted cash flows, collateral value less selling costs (if applicable), or observable market price of the impaired loan is lower than the recorded value of that loan. The general component covers non-classified loans and classified loans that are not evaluated individually for impairment and is based on historical loss experience adjusted for qualitative factors. The Company's historical loss experience is determined by evaluating the average net charge-offs over the most recent economic cycle, but not to exceed six years. Qualitative factors are determined by loan type and allow management to adjust reserve levels to reflect the current general economic environment and portfolio performance trends including recent charge-off trends. Allowances are provided based on management’s continuing evaluation of the pertinent factors underlying the quality of the loan portfolio, including changes in the size and composition of the loan portfolio, actual loan loss experience, current economic conditions, collateral values, geographic concentrations, seasoning of the loan portfolio, specific industry conditions, the duration of the current business cycle, and regulatory requirements and expectations. The appropriateness of the allowance for loan losses is estimated based upon these factors and trends identified by management at the time consolidated financial statements are prepared. In accordance with GAAP, a loan is considered impaired when it is probable that a creditor will be unable to collect all amounts (principal and interest) when due according to the contractual terms of the loan agreement. Smaller balance homogeneous loans, such as residential mortgage loans and consumer loans, may be collectively evaluated for impairment. When a loan has been identified as being impaired, the amount of the impairment is measured by using discounted cash flows, except when, as an alternative, the current estimated fair value of the collateral, reduced by estimated costs to sell (if applicable), or observable market price is used. The valuation of real estate collateral is subjective in nature and may be adjusted in future periods because of changes in economic conditions. Management considers third-party appraisals, as well as independent fair market value assessments from realtors or persons involved in selling real estate, in determining the estimated fair value of particular properties. In addition, as certain of these third-party appraisals and independent fair market value assessments are only updated periodically, changes in the values of specific properties may have occurred subsequent to the most recent appraisals. Accordingly, the amounts of any such potential changes and any related adjustments are generally recorded at the time such information is received. When the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest and net deferred loan origination fees or costs), impairment is recognized by creating or adjusting an allocation of the allowance for loan losses and uncollected accrued interest is reversed against interest income. If ultimate collection of principal is in doubt, all cash receipts on impaired loans are applied to reduce the principal balance. A provision for (recapture of) loan losses is charged (credited) to operations and is added to (deducted from) the allowance for loan losses based on a quarterly comprehensive analysis of the loan portfolio. The allowance for loan losses is allocated to certain loan categories based on the relative risk characteristics, asset classifications and actual loss experience of the loan portfolio. While management has allocated the allowance for loan losses to various loan portfolio segments, the allowance is general in nature and is available for the loan portfolio in its entirety. The ultimate recovery of all loans is susceptible to future market factors beyond the Company’s control. These factors may result in losses or recoveries differing significantly from those provided in the consolidated financial statements. If real estate values decline and as updated appraisals are received on collateral for impaired loans, the Company may need to increase the allowance for loan losses appropriately. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations. Premises and Equipment Premises and equipment are recorded at cost. Depreciation is computed using the straight-line method over the following estimated useful lives: buildings and improvements - five to 40 years; furniture and equipment - three to seven years; and automobiles - five years. The cost of maintenance and repairs is charged to expense as incurred. Gains and losses on dispositions are reflected in earnings. Impairment of Long-Lived Assets Long-lived assets, consisting of premises and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the recorded amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the recorded amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the recorded amount of the assets exceeds the discounted recovery amount or estimated fair value of the assets. No events or changes in circumstances have occurred during the years ended September 30, 2016 or 2015 that would cause management to evaluate the recoverability of the Company’s long-lived assets. OREO and Other Repossessed Assets OREO and other repossessed assets consist of properties or assets acquired through or in lieu of foreclosure, and are recorded initially at the estimated fair value of the properties less estimated costs of disposal, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. When the property is acquired, any excess of the loan balance over the estimated net realizable value is charged to the allowance for loan losses. Costs relating to development and improvement of the properties or assets are capitalized, while costs relating to holding the properties or assets are expensed. The valuation of real estate is subjective in nature and may be adjusted in future periods because of changes in economic conditions. Management considers third-party appraisals, as well as independent fair market value assessments from realtors or persons involved in selling real estate, in determining the estimated fair value of particular properties. In addition, as certain of these third-party appraisals and independent fair market value assessments are only updated periodically, changes in the values of specific properties may have occurred subsequent to the most recent appraisals. Accordingly, the amounts of any such potential changes and any related adjustments are generally recorded at the time such information is received. BOLI BOLI policies are recorded at their cash surrender value less applicable cash surrender charges. Income from BOLI is recognized when earned. Goodwill Goodwill is initially recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired. Goodwill is presumed to have an indefinite useful life and is analyzed annually for impairment. The Company performs an annual review during the third quarter of each fiscal year, or more frequently if indicators of potential impairment exist, to determine if the recorded goodwill is impaired. The goodwill impairment test involves a two-step process. Step one estimates the fair value of the reporting unit. If the estimated fair value of the Company's sole reporting unit, the Bank, under step one exceeds the recorded value of the reporting unit, goodwill is not considered impaired, and no further analysis is necessary. If the estimated fair value of the Company's sole reporting unit is less than the recorded value, then a step two test, which calculates the fair value of assets and liabilities to calculate an implied value of goodwill, is performed. The Company performed its fiscal year 2016 goodwill impairment test during the quarter ended June 30, 2016 with the assistance of an independent third-party firm specializing in goodwill impairment valuations for financial institutions. The third-party analysis was conducted as of May 31, 2016 and the step one test concluded that the reporting unit's fair value was greater than its recorded value, and, therefore, the recorded value of goodwill as of May 31, 2016 was not impaired. Accordingly, step two of the analysis was not necessary. Step one of the goodwill impairment test estimated the fair value of the reporting unit utilizing a discounted cash flow income approach analysis, a public company market approach analysis, a merger and acquisition market approach analysis and a trading price market approach analysis in order to derive an enterprise value for the Company. The discounted cash flow income approach analysis uses a reporting unit's projection of estimated operating results and cash flows and discounts them using a rate that reflects current market conditions. The projection uses management's estimates of economic and market conditions over the projected period including growth rates in loans and deposits, estimates of future expected changes in net interest margins and cash expenditures. Key assumptions used by the Company in its discounted cash flow model (income approach) included an annual loan growth rate that ranged from 3.00% to 3.90%, an annual deposit growth rate that ranged from 2.50% to 3.50% and a return on assets that ranged from 0.90% to 1.10%. In addition to the above projections of estimated operating results, key assumptions used to determine the fair value estimate under this approach were the discount rate of 10.6% and the residual capitalization rate of 7.6%. The discount rate used was the cost of equity capital. The cost of equity capital was based on the capital asset pricing model ("CAPM"), modified to account for a small stock premium. The small stock premium represents the additional return required by investors for small stocks based on the Duffs and Phelps 2016 Valuation Handbook. Beyond the approximate five-year forecast period, residual free cash flows were estimated to increase at a constant rate into perpetuity. These cash flows were converted to a residual value using an appropriate residual capitalization rate. The residual capitalization rate was equal to the discount rate minus the expected long-term growth rate of cash flows. Based on historical results, the economic climate, the outlook for the industry and management's expectations, a long-term growth rate of 3.0% was estimated. The public company market approach analysis estimates the fair value by applying cash flow multiples to the reporting unit's operating performance. The multiples are derived from comparable publicly traded companies with operating and investment characteristics similar to those of the Company. Key assumptions used by the Company included the selection of comparable public companies and performance ratios. In applying the public company analysis, the Company selected nine publicly traded institutions based on similar lines of business, markets, growth prospects, risks and firm size. The performance ratios included price to earnings (last twelve months), price to earnings (current year to date), price to book value, price to tangible book value and price to deposits. The merger and acquisition market approach analysis estimates the fair value by using merger and acquisition transactions involving companies that are similar in nature to the Company. Key assumptions used by the Company included the selection of comparable merger and acquisition transactions and valuation ratios to be used. The analysis used banks located in Washington or Oregon that were acquired after January 1, 2013. The valuation ratios from these transactions for price to earnings and price to tangible book value were then used to derive an estimated fair value of the Company. The trading price market approach analysis used the closing market price at May 31, 2016 of the Company's common stock, traded on the NASDAQ Global Market, to determine the market value of total equity capital. A key assumption used by the Company in the public company market approach analysis and the trading price market approach analysis was the application of a control premium. The Company's common stock is thinly traded, and therefore management believes the trading price reflects a discount for illiquidity. In addition, the trading price of the Company's common stock reflects a minority interest value. To determine the fair market value of a majority interest in the Company's stock, premiums were calculated and applied to the indicated values. Therefore, a control premium was applied to the results of the discounted cash flow income approach analysis, the public company market approach analysis and the trading price market approach analysis because the initial value conclusion was based on minority interest transactions. Merger and acquisition studies were analyzed to conclude that the difference between the acquisition price and a company's stock price prior to acquisition indicates, in part, the price effect of a controlling interest. Based on the evaluation of merger and acquisition studies, a control premium of 25% was used. A significant amount of judgment is involved in determining if an indicator of goodwill impairment has occurred. Such indicators may include, among others: a significant decline in the expected future cash flows; a sustained, significant decline in the Company's stock price and market capitalization; a significant adverse change in legal factors or in the business climate; adverse assessment or action by a regulator; and unanticipated competition. Key assumptions used in the annual goodwill impairment test are highly judgmental and include: selection of comparable companies, amount of control premium, projected cash flows and discount rate applied to projected cash flows. Any change in these indicators or key assumptions could have a significant negative impact on the Company's financial condition, impact the goodwill impairment analysis or cause the Company to perform a goodwill impairment analysis more frequently than once per year. As of September 30, 2016, management believes that there had been no events or changes in the circumstances since May 31, 2016 that would indicate a potential impairment of goodwill. No assurances can be given, however, that the Company will not record an impairment loss on goodwill in the future. MSRs The Company holds rights to service 1) loans that it has originated and sold to the Federal Home Loan Mortgage Corporation (“Freddie Mac”) and 2) the guaranteed portion of U.S. Small Business Administration ("SBA") loans sold in the secondary market. MSRs are capitalized at estimated fair value when acquired through the origination of loans that are subsequently sold with the servicing rights retained and are amortized to servicing income on loans sold approximately in proportion to and over the period of estimated net servicing income. The value of MSRs at the date of the sale of loans is estimated based on the discounted present value of expected future cash flows using key assumptions for servicing income and costs and expected prepayment rates on the underlying loans. The estimated fair value is periodically evaluated for impairment by comparing actual cash flows and estimated future cash flows from the servicing assets to those estimated at the time the servicing assets were originated. Fair values are estimated using expected future discounted cash flows based on current market rates of interest. For purposes of measuring impairment, the MSRs must be stratified by one or more predominant risk characteristics of the underlying loans. The Company stratifies its capitalized MSRs based on product type and term of the underlying loans. The amount of impairment recognized is the amount, if any, by which the amortized cost of the MSRs exceeds their fair value. Impairment, if deemed temporary, is recognized through a valuation allowance to the extent that fair value is less than the recorded amount. 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 Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Income Taxes The Company files a consolidated federal income tax return. The Bank provides for income taxes separately and remits to (receives from) Timberland Bancorp amounts currently due (receivable). Deferred federal income taxes result from temporary differences between the tax basis of assets and liabilities, and their reported amounts in the consolidated financial statements. These temporary differences will result in differences between income for tax purposes and income for financial reporting purposes in future years. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established to reduce the net recorded amount of deferred tax assets if it is determined to be more likely than not that all or some portion of the potential deferred tax asset will not be realized. With respect to accounting for uncertainty in incomes taxes, a tax provision is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely to be realized upon examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and/or penalties related to income tax matters as income tax expense. The Company is no longer subject to U.S. federal income tax examination by tax authorities for years ended on or before September 30, 2012. ESOP The Bank sponsors a leveraged ESOP. The debt of the ESOP - which is payable to Timberland Bancorp - is recorded as other borrowed funds of the Bank and is eliminated in the consolidated financial statements. The shares of the Company's common stock pledged as collateral for the ESOP's debt are reported as unearned shares issued to the ESOP in the consolidated financial statements. As shares are released from collateral, compensation expense is recorded equal to the average market price of the shares for the period, and the shares become available for net income per common share calculations. Dividends paid on unallocated shares reduce the Company’s cash contributions to the ESOP. Advertising Costs for advertising and marketing are expensed as incurred. Stock-Based Compensation The Company measures compensation cost for all stock-based awards based on the grant-date fair value of the stock-based awards and recognizes compensation cost over the service period of stock-based awards. The fair value of stock options is determined using the Black-Scholes valuation model. The Company’s stock compensation plans are described more fully in Note 13. Net Income Per Common Share Basic net income per common share is computed by dividing net income to common shareholders by the weighted average number of common shares outstanding during the period, without considering any dilutive items. Diluted net income per common share is computed by dividing net income to common shareholders by the weighted average number of common shares and common stock equivalents for items that are dilutive, net of shares assumed to be repurchased using the treasury stock method at the average share price for Timberland Bancorp's common stock during the period. During the year ended September 30, 2014, the 5% dividend and related accretion for the amount of the Company's Series A Preferred Stock outstanding was deducted from net income in computing net income to common shareholders. Common stock equivalents arise from the assumed conversion of outstanding stock options and the outstanding warrant to purchase common stock. Shares owned by the Bank’s ESOP that have not been allocated are not considered to be outstanding for the purpose of computing net income per common share. Related Party Transactions The Chairman of the Board of the Bank and Timberland Bancorp is a member of the law firm that provides general counsel to the Company. Legal and other fees paid to this law firm for the years ended September 30, 2016, 2015 and 2014 totaled $127,000, $164,000 and $179,000, respectively. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606). The core principle of this ASU is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In general, the new guidance requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract and estimating the amount of variable consideration to include in the transaction price related to each separate performance obligation. This ASU is effective for annual periods beginning after December 15, 2017, including interim periods within that reporting period. The adoption of ASU No. 2014-09 is not expected to have a material impact on the Company's consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The main provisions of this ASU address the valuation and impairment of certain equity investments along with simplified disclosures about those investments. Equity securities with readily determinable fair values will be treated in the same manner as other financial instruments. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The adoption of ASU No. 2016-01 is not expected to have a material impact on the Company's consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This ASU is intended to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The principal change required by this ASU relates to lessee accounting, and is that for operating leases, a lessee is required to (1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, (2) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis, and (3) classify all cash payments within operating activities in the statement of cash flows. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. This ASU also changes disclosure requirements related to leasing activities and requires certain qualitative disclosures along with specific quantitative disclosures. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early application of the amendments in this ASU is permitted. The Company is currently evaluating the impact that the adoption of ASU No. 2016-02 will have on the Company's future consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. This ASU includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. This ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. The Company is currently evaluating the impact that the adoption of ASU No. 2016-09 will have on the Company's future consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses. This ASU replaces the existing incurred losses methodology for estimating allowances with a current expected credit losses methodology with respect to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held to maturity investment securities and off-balance sheet commitments. In addition, this ASU requires credit losses relating to available for sale debt securities to be recorded through an allowance for credit losses rather than a reduction of the carrying amount. ASU No. 2016-13 also changes the accounting for purchased credit-impaired debt securities and loans. The standard retains many of the current disclosure requirements in current GAAP and expands certain disclosure requirements. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of ASU No. 2016-13 will have on the Company’s future consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Payments. This ASU is intended to reduce diversity in practice in how certain transactions are presented and classified in the statement of cash flows. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently evaluating the impact that the adoption of ASU No. 2016-15 will have on the Company's future consolidated financial statements.

Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Timberland Bancorp, Inc. (“Timberland Bancorp”); its wholly owned subsidiary, Timberland Bank (the “Bank”); and the Bank’s wholly owned subsidiary, Timberland Service Corp. (collectively, the "Company”). All significant intercompany transactions and balances have been eliminated in consolidation.

Nature of Operations

Timberland Bancorp is a bank holding company which operates primarily through its subsidiary, the Bank. The Bank was established in 1915 and, through its 22 branches located in Grays Harbor, Pierce, Thurston, Kitsap, King and Lewis counties in Washington State, attracts deposits from the general public, and uses those funds, along with other borrowings, primarily to provide residential real estate, construction, commercial real estate, commercial business and consumer loans to borrowers primarily in western Washington.

Consolidated Financial Statement Presentation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S.") (“GAAP”) and prevailing practices within the banking industry. The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities, as of the date of the consolidated balance sheets, and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the determination of OTTI in the estimated fair value of investment securities, the valuation of deferred tax assets, the valuation of MSRs, the valuation of OREO and the valuation of goodwill for potential impairment.

Certain prior year amounts have been reclassified to conform to the 2016 fiscal year presentation with no change to previously reported net income or shareholders’ equity.

Segment Reporting

The Company has one reportable operating segment which is defined as community banking in western Washington under the operating name “Timberland Bank.”

Preferred Stock Sold in Troubled Asset Relief Program ("TARP") Capital Purchase Program ("CPP")

On December 23, 2008, the Company received $16.64 million from the U.S. Treasury Department ("Treasury") as a part of the Treasury's CPP, which was established as part of the TARP. The Company sold 16,641 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A ("Series A Preferred Stock"), with a liquidation value of $1,000 per share and a related warrant to purchase 370,899 shares of the Company's common stock at an exercise price of $6.73 per share (subject to anti-dilution adjustments) at any time through December 23, 2018.

The proceeds received in connection with the issuance of the Series A Preferred Stock were allocated between the preferred stock and warrant based on their relative fair values on the date of issuance. As a result, the preferred stock's initial recorded value was at a discount from the liquidation value or stated value. The discount from the liquidation value was accreted to the expected/actual redemption date and charged to retained earnings. This accretion was recorded using the level-yield method.

On November 13, 2012, the Company’s outstanding 16,641 shares of Series A Preferred Stock were sold by the Treasury as part of its efforts to manage and recover its investments under the TARP. While the sale of the Series A Preferred Stock to new owners did not result in any proceeds to the Company and did not change the Company’s capital position or accounting for these securities, it did eliminate restrictions put in place by the Treasury on TARP recipients.

On June 12, 2013, the Treasury sold the warrant to purchase up to 370,899 shares of the Company’s common stock to private investors. The sale of the warrant to new owners did not result in any proceeds to the Company and did not change the Company's capital position or accounting for the warrant.

During the year ended September 30, 2013, the Company purchased and retired 4,576 shares of its Series A Preferred Stock for $4.32 million; a $255,000 discount from its liquidation value. The discount from liquidation value on the repurchased shares was recorded as an increase to retained earnings. On December 20, 2013, the Company redeemed the remaining 12,065 shares of its Series A Preferred Stock at the liquidation value of $12.07 million. The Series A Preferred Stock paid a 5.0% dividend through December 20, 2013, the date of its redemption.

Cash and Cash Equivalents and Cash Flows

The Company considers amounts included in the consolidated balance sheets’ captions “Cash and due from financial institutions” and “Interest-bearing deposits in banks,” all of which mature within ninety days, to be cash equivalents for purposes of reporting cash flows. Cash flows from loans, deposits, FHLB borrowings and repurchase agreements are reported net in the accompanying consolidated statements of cash flows.

Interest-bearing deposits in banks as of September 30, 2016 and 2015 included deposits with the Federal Reserve Bank of San Francisco ("FRB") of $88,420,000 and $70,975,000, respectively. The Company also maintains balances in correspondent bank accounts which, at times, may exceed FDIC insurance limits of $250,000. Management believes that its risk of loss associated with such balances is minimal due to the financial strength of the FRB and the correspondent banks.

CDs Held for Investment

CDs held for investment include amounts invested with other FDIC-insured financial institutions for a stated interest rate and with a fixed maturity date. Such CDs generally have a maturity of 12 to 24 months from the date of purchase by the Company. Early withdrawal penalties may apply; however, the Company intends to hold these CDs to maturity. The Company generally limits its purchases of CDs to a maximum of $250,000 (the FDIC insurance coverage limit) with any single financial institution.

Investment Securities

Investment securities are classified upon acquisition as either held to maturity or available for sale. Investment securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and reflected at amortized cost. Investment securities classified as available for sale are reflected at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income (loss), net of income tax effects. Premiums and discounts are amortized to earnings using the interest method over the contractual lives of the securities. Gains and losses on sales of investment securities are recognized on the trade date and determined using the specific identification method.

In estimating whether there are any OTTI losses, management considers (1) the length of time and the extent to which the fair value has been less than amortized cost, (2) the financial condition and near term prospects of the issuer, (3) the impact of changes in market interest rates and (4) the intent and ability of the Company to retain its investment for a period of time sufficient to allow for any anticipated recovery in fair value.

Declines in the fair value of individual investment securities available for sale that are deemed to be other than temporary are reflected in earnings when identified. The fair value of the investment security then becomes the new cost basis. For individual investment securities that are held to maturity which the Company does not intend to sell, and it is not more likely than not that the Company will be required to sell before recovery of its amortized cost basis, the other than temporary decline in the fair value of the investment security related to: (1) credit loss is recognized in earnings and (2) market or other factors is recognized in other comprehensive income (loss). Credit loss is recorded if the present value of expected future cash flows is less than the amortized cost. For individual investment securities which the Company intends to sell or more likely than not will not recover all of its amortized cost, the OTTI is recognized in earnings equal to the entire difference between the investment security’s cost basis and its fair value at the consolidated balance sheet date. For individual investment securities for which credit loss has been recognized in earnings, interest accruals and amortization and accretion of premiums and discounts are suspended when the credit loss is recognized. Interest received after accruals have been suspended is recognized on a cash basis.

FHLB Stock

The Bank, as a member of the FHLB, is required to maintain an investment in capital stock of the FHLB in an amount equal to 0.12% of the Bank's total assets plus 4.00% of borrowings from the FHLB. No ready market exists for this stock, and it has no quoted market value. However, redemption of FHLB stock has historically been at par value. The Company's investment in FHLB stock is carried at cost, which approximates fair value.

The Company evaluates its FHLB stock for impairment as needed. The Company's determination of whether this investment is impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared with the capital stock amount and the length of time any decline has persisted; (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB; and (4) the liquidity position of the FHLB. Based on its evaluation, the Company determined that there was no impairment of FHLB stock at September 30, 2016 and 2015.

Loans Held for Sale

Mortgage loans and commercial business loans originated and intended for sale in the secondary market are stated in the aggregate at the lower of cost or estimated fair value. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Gains or losses on sales of loans are recognized at the time of sale. The gain or loss is the difference between the net sales proceeds and the recorded value of the loans, including any remaining unamortized deferred loan origination fees.

Loans Receivable

Loans are stated at the amount of unpaid principal, reduced by the undisbursed portion of construction loans in process, deferred loan origination fees and the allowance for loan losses.

Interest on loans is accrued daily based on the principal amount outstanding. Generally, the accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to make payments as they become due or when they are past due 90 days as to either principal or interest (based on contractual terms), unless the loan is well secured and in the process of collection. In determining whether a borrower may be able to make payments as they become due, management considers circumstances such as the financial strength of the borrower, the estimated collateral value, reasons for the delays in payments, payment record, the amounts past due and the number of days past due. All interest accrued but not collected for loans that are placed on non-accrual status or charged off is reversed against interest income. Subsequent collections on a cash basis are applied proportionately to past due principal and interest, unless collectability of principal is in doubt, in which case all payments are applied to principal. Loans are returned to accrual status when the loan is deemed current, and the collectability of principal and interest is no longer doubtful, or, in the case of one- to four-family loans, when the loan is less than 90 days delinquent. The categories of non-accrual loans and impaired loans overlap, although they are not identical.

The Company charges fees for originating loans. These fees, net of certain loan origination costs, are deferred and amortized to income on the level-yield basis over the loan term. If the loan is repaid prior to maturity, the remaining unamortized deferred loan origination fee is recognized in income at the time of repayment.

Troubled Debt Restructured Loans

A troubled debt restructured loan ("TDR") is a loan for which the Company, for reasons related to a borrower’s financial difficulties, grants a significant concession to the borrower that the Company would not otherwise consider. Examples of such concessions include, but are not limited to: a reduction in the stated interest rate; an extension of the maturity at an interest rate below current market rates; a reduction in the face amount of the debt; a reduction in the accrued interest; or re-amortizations, extensions, deferrals and renewals. Troubled debt restructured loans are considered impaired and are individually evaluated for impairment. Troubled debt restructured loans are classified as non-accrual (and considered to be non-performing) unless they have been performing in accordance with modified terms for a period of at least six months.

Allowance for Loan Losses

The allowance for loan losses is maintained at a level sufficient to provide for probable losses inherent in the loan portfolio. The allowance is provided based upon management's comprehensive analysis of the pertinent factors underlying the quality of the loan portfolio. These factors include changes in the amount and composition of the loan portfolio, delinquency levels, actual loan loss experience, current economic conditions, and a detailed analysis of individual loans for which full collectability may not be assured. The detailed analysis includes methods to estimate the fair value of loan collateral and the existence of potential alternative sources of repayment. The allowance consists of specific and general components. The specific component relates to loans that are deemed impaired. For such loans that are classified as impaired, an allowance is established when the discounted cash flows, collateral value less selling costs (if applicable), or observable market price of the impaired loan is lower than the recorded value of that loan. The general component covers non-classified loans and classified loans that are not evaluated individually for impairment and is based on historical loss experience adjusted for qualitative factors. The Company's historical loss experience is determined by evaluating the average net charge-offs over the most recent economic cycle, but not to exceed six years. Qualitative factors are determined by loan type and allow management to adjust reserve levels to reflect the current general economic environment and portfolio performance trends including recent charge-off trends. Allowances are provided based on management’s continuing evaluation of the pertinent factors underlying the quality of the loan portfolio, including changes in the size and composition of the loan portfolio, actual loan loss experience, current economic conditions, collateral values, geographic concentrations, seasoning of the loan portfolio, specific industry conditions, the duration of the current business cycle, and regulatory requirements and expectations. The appropriateness of the allowance for loan losses is estimated based upon these factors and trends identified by management at the time consolidated financial statements are prepared.

In accordance with GAAP, a loan is considered impaired when it is probable that a creditor will be unable to collect all amounts (principal and interest) when due according to the contractual terms of the loan agreement. Smaller balance homogeneous loans, such as residential mortgage loans and consumer loans, may be collectively evaluated for impairment. When a loan has been identified as being impaired, the amount of the impairment is measured by using discounted cash flows, except when, as an alternative, the current estimated fair value of the collateral, reduced by estimated costs to sell (if applicable), or observable market price is used. The valuation of real estate collateral is subjective in nature and may be adjusted in future periods because of changes in economic conditions. Management considers third-party appraisals, as well as independent fair market value assessments from realtors or persons involved in selling real estate, in determining the estimated fair value of particular properties. In addition, as certain of these third-party appraisals and independent fair market value assessments are only updated periodically, changes in the values of specific properties may have occurred subsequent to the most recent appraisals. Accordingly, the amounts of any such potential changes and any related adjustments are generally recorded at the time such information is received. When the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest and net deferred loan origination fees or costs), impairment is recognized by creating or adjusting an allocation of the allowance for loan losses and uncollected accrued interest is reversed against interest income. If ultimate collection of principal is in doubt, all cash receipts on impaired loans are applied to reduce the principal balance.

A provision for (recapture of) loan losses is charged (credited) to operations and is added to (deducted from) the allowance for loan losses based on a quarterly comprehensive analysis of the loan portfolio. The allowance for loan losses is allocated to certain loan categories based on the relative risk characteristics, asset classifications and actual loss experience of the loan portfolio. While management has allocated the allowance for loan losses to various loan portfolio segments, the allowance is general in nature and is available for the loan portfolio in its entirety.

The ultimate recovery of all loans is susceptible to future market factors beyond the Company’s control. These factors may result in losses or recoveries differing significantly from those provided in the consolidated financial statements. If real estate values decline and as updated appraisals are received on collateral for impaired loans, the Company may need to increase the allowance for loan losses appropriately. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations.

Premises and Equipment

Premises and equipment are recorded at cost. Depreciation is computed using the straight-line method over the following estimated useful lives: buildings and improvements - five to 40 years; furniture and equipment - three to seven years; and automobiles - five years. The cost of maintenance and repairs is charged to expense as incurred. Gains and losses on dispositions are reflected in earnings.

Impairment of Long-Lived Assets

Long-lived assets, consisting of premises and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the recorded amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the recorded amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the recorded amount of the assets exceeds the discounted recovery amount or estimated fair value of the assets. No events or changes in circumstances have occurred during the years ended September 30, 2016 or 2015 that would cause management to evaluate the recoverability of the Company’s long-lived assets.

OREO and Other Repossessed Assets

OREO and other repossessed assets consist of properties or assets acquired through or in lieu of foreclosure, and are recorded initially at the estimated fair value of the properties less estimated costs of disposal, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. When the property is acquired, any excess of the loan balance over the estimated net realizable value is charged to the allowance for loan losses. Costs relating to development and improvement of the properties or assets are capitalized, while costs relating to holding the properties or assets are expensed. The valuation of real estate is subjective in nature and may be adjusted in future periods because of changes in economic conditions. Management considers third-party appraisals, as well as independent fair market value assessments from realtors or persons involved in selling real estate, in determining the estimated fair value of particular properties. In addition, as certain of these third-party appraisals and independent fair market value assessments are only updated periodically, changes in the values of specific properties may have occurred subsequent to the most recent appraisals. Accordingly, the amounts of any such potential changes and any related adjustments are generally recorded at the time such information is received.

BOLI

BOLI policies are recorded at their cash surrender value less applicable cash surrender charges. Income from BOLI is recognized when earned.

Goodwill

Goodwill is initially recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired. Goodwill is presumed to have an indefinite useful life and is analyzed annually for impairment. The Company performs an annual review during the third quarter of each fiscal year, or more frequently if indicators of potential impairment exist, to determine if the recorded goodwill is impaired.

The goodwill impairment test involves a two-step process. Step one estimates the fair value of the reporting unit. If the estimated fair value of the Company's sole reporting unit, the Bank, under step one exceeds the recorded value of the reporting unit, goodwill is not considered impaired, and no further analysis is necessary. If the estimated fair value of the Company's sole reporting unit is less than the recorded value, then a step two test, which calculates the fair value of assets and liabilities to calculate an implied value of goodwill, is performed.

The Company performed its fiscal year 2016 goodwill impairment test during the quarter ended June 30, 2016 with the assistance of an independent third-party firm specializing in goodwill impairment valuations for financial institutions. The third-party analysis was conducted as of May 31, 2016 and the step one test concluded that the reporting unit's fair value was greater than its recorded value, and, therefore, the recorded value of goodwill as of May 31, 2016 was not impaired. Accordingly, step two of the analysis was not necessary.

Step one of the goodwill impairment test estimated the fair value of the reporting unit utilizing a discounted cash flow income approach analysis, a public company market approach analysis, a merger and acquisition market approach analysis and a trading price market approach analysis in order to derive an enterprise value for the Company.

The discounted cash flow income approach analysis uses a reporting unit's projection of estimated operating results and cash flows and discounts them using a rate that reflects current market conditions. The projection uses management's estimates of economic and market conditions over the projected period including growth rates in loans and deposits, estimates of future expected changes in net interest margins and cash expenditures. Key assumptions used by the Company in its discounted cash flow model (income approach) included an annual loan growth rate that ranged from 3.00% to 3.90%, an annual deposit growth rate that ranged from 2.50% to 3.50% and a return on assets that ranged from 0.90% to 1.10%. In addition to the above projections of estimated operating results, key assumptions used to determine the fair value estimate under this approach were the discount rate of 10.6% and the residual capitalization rate of 7.6%. The discount rate used was the cost of equity capital. The cost of equity capital was based on the capital asset pricing model ("CAPM"), modified to account for a small stock premium. The small stock premium represents the additional return required by investors for small stocks based on the Duffs and Phelps 2016 Valuation Handbook. Beyond the approximate five-year forecast period, residual free cash flows were estimated to increase at a constant rate into perpetuity. These cash flows were converted to a residual value using an appropriate residual capitalization rate. The residual capitalization rate was equal to the discount rate minus the expected long-term growth rate of cash flows. Based on historical results, the economic climate, the outlook for the industry and management's expectations, a long-term growth rate of 3.0% was estimated.

The public company market approach analysis estimates the fair value by applying cash flow multiples to the reporting unit's operating performance. The multiples are derived from comparable publicly traded companies with operating and investment characteristics similar to those of the Company. Key assumptions used by the Company included the selection of comparable public companies and performance ratios. In applying the public company analysis, the Company selected nine publicly traded institutions based on similar lines of business, markets, growth prospects, risks and firm size. The performance ratios included price to earnings (last twelve months), price to earnings (current year to date), price to book value, price to tangible book value and price to deposits.

The merger and acquisition market approach analysis estimates the fair value by using merger and acquisition transactions involving companies that are similar in nature to the Company. Key assumptions used by the Company included the selection of comparable merger and acquisition transactions and valuation ratios to be used. The analysis used banks located in Washington or Oregon that were acquired after January 1, 2013. The valuation ratios from these transactions for price to earnings and price to tangible book value were then used to derive an estimated fair value of the Company.

The trading price market approach analysis used the closing market price at May 31, 2016 of the Company's common stock, traded on the NASDAQ Global Market, to determine the market value of total equity capital.

A key assumption used by the Company in the public company market approach analysis and the trading price market approach analysis was the application of a control premium. The Company's common stock is thinly traded, and therefore management believes the trading price reflects a discount for illiquidity. In addition, the trading price of the Company's common stock reflects a minority interest value. To determine the fair market value of a majority interest in the Company's stock, premiums were calculated and applied to the indicated values. Therefore, a control premium was applied to the results of the discounted cash flow income approach analysis, the public company market approach analysis and the trading price market approach analysis because the initial value conclusion was based on minority interest transactions. Merger and acquisition studies were analyzed to conclude that the difference between the acquisition price and a company's stock price prior to acquisition indicates, in part, the price effect of a controlling interest. Based on the evaluation of merger and acquisition studies, a control premium of 25% was used.

A significant amount of judgment is involved in determining if an indicator of goodwill impairment has occurred. Such indicators may include, among others: a significant decline in the expected future cash flows; a sustained, significant decline in the Company's stock price and market capitalization; a significant adverse change in legal factors or in the business climate; adverse assessment or action by a regulator; and unanticipated competition. Key assumptions used in the annual goodwill impairment test are highly judgmental and include: selection of comparable companies, amount of control premium, projected cash flows and discount rate applied to projected cash flows. Any change in these indicators or key assumptions could have a significant negative impact on the Company's financial condition, impact the goodwill impairment analysis or cause the Company to perform a goodwill impairment analysis more frequently than once per year.

As of September 30, 2016, management believes that there had been no events or changes in the circumstances since May 31, 2016 that would indicate a potential impairment of goodwill. No assurances can be given, however, that the Company will not record an impairment loss on goodwill in the future.

MSRs

The Company holds rights to service 1) loans that it has originated and sold to the Federal Home Loan Mortgage Corporation (“Freddie Mac”) and 2) the guaranteed portion of U.S. Small Business Administration ("SBA") loans sold in the secondary market. MSRs are capitalized at estimated fair value when acquired through the origination of loans that are subsequently sold with the servicing rights retained and are amortized to servicing income on loans sold approximately in proportion to and over the period of estimated net servicing income. The value of MSRs at the date of the sale of loans is estimated based on the discounted present value of expected future cash flows using key assumptions for servicing income and costs and expected prepayment rates on the underlying loans. The estimated fair value is periodically evaluated for impairment by comparing actual cash flows and estimated future cash flows from the servicing assets to those estimated at the time the servicing assets were originated. Fair values are estimated using expected future discounted cash flows based on current market rates of interest. For purposes of measuring impairment, the MSRs must be stratified by one or more predominant risk characteristics of the underlying loans. The Company stratifies its capitalized MSRs based on product type and term of the underlying loans. The amount of impairment recognized is the amount, if any, by which the amortized cost of the MSRs exceeds their fair value. Impairment, if deemed temporary, is recognized through a valuation allowance to the extent that fair value is less than the recorded amount.

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 Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

Income Taxes

The Company files a consolidated federal income tax return. The Bank provides for income taxes separately and remits to (receives from) Timberland Bancorp amounts currently due (receivable).

Deferred federal income taxes result from temporary differences between the tax basis of assets and liabilities, and their reported amounts in the consolidated financial statements. These temporary differences will result in differences between income for tax purposes and income for financial reporting purposes in future years. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established to reduce the net recorded amount of deferred tax assets if it is determined to be more likely than not that all or some portion of the potential deferred tax asset will not be realized.

With respect to accounting for uncertainty in incomes taxes, a tax provision is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely to be realized upon examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and/or penalties related to income tax matters as income tax expense. The Company is no longer subject to U.S. federal income tax examination by tax authorities for years ended on or before September 30, 2012.

ESOP

The Bank sponsors a leveraged ESOP. The debt of the ESOP - which is payable to Timberland Bancorp - is recorded as other borrowed funds of the Bank and is eliminated in the consolidated financial statements. The shares of the Company's common stock pledged as collateral for the ESOP's debt are reported as unearned shares issued to the ESOP in the consolidated financial statements. As shares are released from collateral, compensation expense is recorded equal to the average market price of the shares for the period, and the shares become available for net income per common share calculations. Dividends paid on unallocated shares reduce the Company’s cash contributions to the ESOP.

Advertising

Costs for advertising and marketing are expensed as incurred.

Stock-Based Compensation

The Company measures compensation cost for all stock-based awards based on the grant-date fair value of the stock-based awards and recognizes compensation cost over the service period of stock-based awards. The fair value of stock options is determined using the Black-Scholes valuation model. The Company’s stock compensation plans are described more fully in Note 13.

Net Income Per Common Share

Basic net income per common share is computed by dividing net income to common shareholders by the weighted average number of common shares outstanding during the period, without considering any dilutive items. Diluted net income per common share is computed by dividing net income to common shareholders by the weighted average number of common shares and common stock equivalents for items that are dilutive, net of shares assumed to be repurchased using the treasury stock method at the average share price for Timberland Bancorp's common stock during the period. During the year ended September 30, 2014, the 5% dividend and related accretion for the amount of the Company's Series A Preferred Stock outstanding was deducted from net income in computing net income to common shareholders. Common stock equivalents arise from the assumed conversion of outstanding stock options and the outstanding warrant to purchase common stock. Shares owned by the Bank’s ESOP that have not been allocated are not considered to be outstanding for the purpose of computing net income per common share.

Related Party Transactions

The Chairman of the Board of the Bank and Timberland Bancorp is a member of the law firm that provides general counsel to the Company. Legal and other fees paid to this law firm for the years ended September 30, 2016, 2015 and 2014 totaled $127,000, $164,000 and $179,000, respectively.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606). The core principle of this ASU is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In general, the new guidance requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract and estimating the amount of variable consideration to include in the transaction price related to each separate performance obligation. This ASU is effective for annual periods beginning after December 15, 2017, including interim periods within that reporting period. The adoption of ASU No. 2014-09 is not expected to have a material impact on the Company's consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The main provisions of this ASU address the valuation and impairment of certain equity investments along with simplified disclosures about those investments. Equity securities with readily determinable fair values will be treated in the same manner as other financial instruments. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The adoption of ASU No. 2016-01 is not expected to have a material impact on the Company's consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This ASU is intended to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The principal change required by this ASU relates to lessee accounting, and is that for operating leases, a lessee is required to (1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, (2) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis, and (3) classify all cash payments within operating activities in the statement of cash flows. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. This ASU also changes disclosure requirements related to leasing activities and requires certain qualitative disclosures along with specific quantitative disclosures. The amendments in this ASU are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early application of the amendments in this ASU is permitted. The Company is currently evaluating the impact that the adoption of ASU No. 2016-02 will have on the Company's future consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. This ASU includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. This ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. The Company is currently evaluating the impact that the adoption of ASU No. 2016-09 will have on the Company's future consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses. This ASU replaces the existing incurred losses methodology for estimating allowances with a current expected credit losses methodology with respect to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held to maturity investment securities and off-balance sheet commitments. In addition, this ASU requires credit losses relating to available for sale debt securities to be recorded through an allowance for credit losses rather than a reduction of the carrying amount. ASU No. 2016-13 also changes the accounting for purchased credit-impaired debt securities and loans. The standard retains many of the current disclosure requirements in current GAAP and expands certain disclosure requirements. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of ASU No. 2016-13 will have on the Company’s future consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Payments. This ASU is intended to reduce diversity in practice in how certain transactions are presented and classified in the statement of cash flows. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently evaluating the impact that the adoption of ASU No. 2016-15 will have on the Company's future consolidated financial statements.
