PART I

Item 1.  Business

General

Timberland Bancorp, Inc. (“Timberland Bancorp" or the "Company”), a Washington corporation, was organized on September 8, 1997 for the purpose of becoming the holding company for Timberland Bank (the "Bank").  At September 30, 2020, on a consolidated basis, the Company had total assets of $1.57 billion, net loans receivable of $1.01 billion, total deposits of $1.36 billion and total shareholders’ equity of $187.63 million.  The Company’s business activities generally are limited to passive investment activities and oversight of its investment in the Bank.  Accordingly, the information set forth in this report, including consolidated financial statements and related data, relates primarily to the Bank and its subsidiary, Timberland Service Corporation.

The Bank opened for business in 1915 and serves consumers and businesses across Grays Harbor, Thurston, Pierce, King, Kitsap and Lewis counties, Washington with a full range of lending and deposit services through its 24 branches (including its main office in Hoquiam). The Bank’s deposits are insured up to applicable legal limits by the Federal Deposit Insurance Corporation (“FDIC”).  The Bank has been a member of the Federal Home Loan Bank System since 1937.  The Bank is regulated by the Washington Department of Financial Institutions, Division of Banks (“Division” or “DFI”) and the FDIC. The Company is regulated by the Board of Governors of the Federal Reserve System ("Federal Reserve").

On October 1, 2018, the Company completed the acquisition of South Sound Bank, a Washington-state chartered bank, headquartered in Olympia, Washington ("South Sound Acquisition"). The Company acquired 100% of the outstanding common stock of South Sound Bank, and South Sound Bank was merged into the Bank. The results of operations of the acquired assets and assumed liabilities have been included in the Company's consolidated financial statements as of and for the period since the acquisition date. For additional details see Note 2 of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

Timberland Bank is a community-oriented bank which has traditionally offered a variety of savings products to its retail customers while concentrating its lending activities on real estate mortgage loans. Lending activities have been focused primarily on the origination of loans secured by real estate, including residential and commercial / multi-family construction loans, one- to four-family residential loans, multi-family loans, commercial real estate loans and land loans. The Bank originates adjustable-rate residential mortgage loans that do not qualify for sale in the secondary market. The Bank also originates commercial business loans and other consumer loans.

The Company maintains a website at www.timberlandbank.com.  The information contained on that website is not included as a part of, or incorporated by reference into, this Annual Report on Form 10-K.  Other than an investor’s own internet access charges, the Company makes available free of charge through that website the Company’s Annual Report on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, and amendments to these reports, as soon as reasonably practicable after these materials have been electronically filed with, or furnished to, the Securities and Exchange Commission (“SEC”).

Market Area

The Bank considers Grays Harbor, Pierce, Thurston, Kitsap, King and Lewis counties, Washington as its primary market areas.  The Bank conducts operations from:

•its main office in Hoquiam (Grays Harbor County);

•five branch offices in Grays Harbor County (Ocean Shores, Montesano, Elma and two branches in Aberdeen);

•five branch offices in Pierce County (Edgewood, Puyallup, Spanaway, Tacoma and Gig Harbor);

•seven branch offices in Thurston County (Tumwater, Yelm, three branches in Lacey and two branches in Olympia);

•two branch offices in Kitsap County (Poulsbo and Silverdale);

•a branch office in King County (Auburn); and

•three branch offices in Lewis County (Winlock, Toledo and Chehalis).

For additional information, see “Item 2. Properties.”

Hoquiam, with a population of approximately 8,700, is located in Grays Harbor County which is situated along Washington State’s central Pacific coast.  Hoquiam is located approximately 110 miles southwest of Seattle, Washington and 145 miles northwest of Portland, Oregon.

The Bank considers its primary market area to include six sub-markets: primarily rural Grays Harbor County with its historical dependence on the timber and fishing industries; Thurston and Kitsap counties with their dependence on state and federal government; Pierce and King counties with their broadly diversified economic bases; and Lewis County with its dependence on retail trade, manufacturing, industrial services and local government.  Each of these markets presents operating risks to the Bank.  The Bank’s expansion into Pierce, Thurston, Kitsap, King and Lewis counties represents the Bank’s strategy to expand and diversify its primary market area to become less reliant on the economy of Grays Harbor County.

Grays Harbor County has a population of 75,000 according to the United States ("U.S.") Census Bureau 2019 estimates and a median family income of $65,500 according to 2020 estimates from the Department of Housing and Urban Development (“HUD”).  The economic base in Grays Harbor County has been historically dependent on the timber and fishing industries.  Other industries that support the economic base are tourism, agriculture, shipping, transportation and technology.  According to the Washington State Employment Security Department, the unemployment rate in Grays Harbor County increased to 10.0% at September 30, 2020 from 6.7% at September 30, 2019.  The median price of a resale home in Grays Harbor County for the quarter ended June 30, 2020 increased 13.4% to $239,800 from $211,400 for the comparable prior year period.  The number of home sales increased 3.1% for the quarter ended June 30, 2020 compared to the same quarter one year earlier.  The Bank has six branches (including its home office) located in the county.

Lending Activities

General.  Historically, the principal lending activity of the Bank has consisted of the origination of loans secured by first mortgages on owner-occupied, one- to four-family residences, multi-family properties, commercial real estate, or by land and loans for the construction of one- to four-family residences.  The Bank’s net loans receivable totaled $1.01 billion at September 30, 2020, representing 64.7% of consolidated total assets, and at that date commercial real estate, construction (including undisbursed loans in process), multi-family and land loans were $783.69 million, or 69.1% of total loans.  Commercial real estate, construction, multi-family, and land loans typically have higher rates of return than one- to four-family loans; however, they also present a higher degree of risk.  

The Bank’s internal loan policy limits the maximum amount of loans to one borrower to 20% of its capital plus surplus. According to the Washington Administrative Code, capital and surplus are defined as a bank's Tier 1 capital, Tier 2 capital and the balance of a bank's allowance for loan losses not included in the bank's Tier 2 capital as reported in the bank's call report. At September 30, 2020, the maximum amount which the Bank could have lent to any one borrower and the borrower’s related entities was approximately $36.55 million under this policy.  At September 30, 2020, the largest amount outstanding to any one borrower and the borrower’s related entities was $28.88 million (including $4.05 million in available lines of credit), which was secured by various commercial real estate and residential properties and other business assets located primarily in King County and were performing according to their loan repayment terms at September 30, 2020.  The next largest amount outstanding to any one borrower and the borrower’s related entities was $20.59 million (including $7.34 million of undisbursed construction loan proceeds).  These loans were secured by multi-family, one- to four-family and commercial real estate properties located primarily in Thurston County and were performing according to their loan repayment terms at September 30, 2020.

Residential One- to Four-Family Lending.  At September 30, 2020, $118.58 million, or 10.5%, of the Bank’s loan portfolio consisted of loans secured by one- to four-family residences.  The Bank originates both fixed-rate loans and adjustable-rate loans.

Generally, one- to four-family fixed-rate loans are originated to meet the requirements for sale in the secondary market to the Federal Home Loan Mortgage Corporation ("Freddie Mac") or the Federal Home Loan Bank of Des Moines ("FHLB").  From time to time, however, a portion of these fixed-rate loans may be retained in the loan portfolio to meet the Bank’s asset/liability management objectives. The Bank uses an automated underwriting program, which preliminarily qualifies a loan as conforming to Freddie Mac underwriting standards when the loan is originated.  At September 30, 2020, $38.29 million, or 32.3%, of the Bank’s one- to four-family loan portfolio consisted of fixed-rate mortgage loans.

The Bank also offers adjustable-rate mortgage (“ARM”) loans.  All of the Bank’s ARM loans are retained in its loan portfolio.  The Bank offers several ARM products which adjust annually or every three to five years after an initial period ranging from one to five years and are typically subject to a limitation on the annual interest rate increase of 2% and an overall limitation of 6%.  These ARM products generally are re-priced utilizing the weekly average yield on one year U.S. Treasury securities adjusted to a constant maturity of one year plus a margin of 2.75% to 4.00%.  The Bank also offers ARM loans tied to The Wall Street Journal prime lending rate ("Prime Rate") index which typically do not have periodic or lifetime adjustment limits.  Loans tied to the Prime Rate normally have margins ranging up to 3.0%.  ARM loans held in the Bank’s portfolio do not permit negative amortization of principal.  Borrower demand for ARM loans versus fixed-rate mortgage loans is a function of the level of interest rates, the expectations of changes in the level of interest rates and the difference between the initial interest rates and fees charged for each type of loan.  The relative amount of fixed-rate mortgage loans and ARM loans that can be originated at any time is largely determined by the demand for each in a competitive environment.  At September 30, 2020, $80.29 million, or 67.7%, of the Bank’s one- to four- family loan portfolio consisted of ARM loans.

A portion of the Bank’s ARM loans are “non-conforming”, because they do not satisfy acreage limits or various other requirements imposed by Freddie Mac.  Some of these loans are also originated to meet the needs of borrowers who cannot otherwise satisfy Freddie Mac credit requirements because of personal and financial reasons (i.e., divorce, bankruptcy, length of time employed, etc.), and other aspects, which do not conform to Freddie Mac’s guidelines.  Such borrowers may have higher debt-to-income ratios, or the loans are secured by unique properties in rural markets for which there are no sales of comparable properties to support the value according to secondary market requirements.  These loans are known as non-conforming loans, and the Bank may require additional collateral or lower loan-to-value ratios to reduce the risk of these loans.  The Bank believes that these loans satisfy a need in its local market area.  As a result, subject to market conditions, the Bank intends to continue to originate these types of loans.

The retention of ARM loans in the Bank’s loan portfolio helps reduce the Bank’s exposure to changes in interest rates.  There are, however, unquantifiable credit risks resulting from the potential of increased interest to be paid by the customer as a result of increases in interest rates.  It is possible that during periods of rising interest rates the risk of default on ARM loans may increase as a result of repricing and the increased costs to the borrower.  The Bank attempts to reduce the potential for delinquencies and defaults on ARM loans by qualifying the borrower based on the borrower’s ability to repay the ARM loan assuming a 2.0% increase in the initial interest rate.  Another consideration is that although ARM loans allow the Bank to increase the sensitivity of its asset base due to changes in the interest rates, the extent of this interest sensitivity is limited by the periodic and lifetime interest rate adjustment limits.  Because of these considerations, the Bank has no assurance that yield increases on ARM loans will be sufficient to offset increases in the Bank’s cost of funds.

While fixed-rate, single-family residential mortgage loans are normally originated with 15 to 30 year terms to maturity, these loans typically remain outstanding for substantially shorter periods because borrowers often prepay their loans in full upon sale of the property pledged as security or upon refinancing the original loan.  In addition, substantially all mortgage loans in the Bank’s loan portfolio contain due-on-sale clauses providing that the Bank may declare the unpaid amount due and payable upon the sale of the property securing the loan.  Typically, the Bank enforces these due-on-sale clauses to the extent permitted by law and as business judgment dictates.  Thus, average loan maturity is a function of, among other factors, the level of purchase and sale activity in the real estate market, prevailing interest rates and the interest rates received on outstanding loans.

The Bank requires that fire and extended coverage casualty insurance be maintained on the collateral for all of its real estate secured loans and flood insurance, if appropriate.

The Bank’s lending policies generally limit the maximum loan-to-value ratio on mortgage loans secured by owner-occupied properties to 95% of the lesser of the appraised value or the purchase price.  However, the Bank usually obtains private mortgage insurance (“PMI”) on the portion of the principal amount that exceeds 80% of the appraised value of the security property. The maximum loan-to-value ratio on mortgage loans secured by non-owner-occupied properties is generally

8

80% (90% for loans originated for sale in the secondary market to Freddie Mac or the FHLB).  At September 30, 2020, three one- to four-family loans totaling $659,000 were on non-accrual status.  See “Lending Activities - Non-performing Loans and Delinquencies.”

Multi-Family Lending.  At September 30, 2020, $85.05 million, or 7.5%, of the Bank’s total loan portfolio was secured by multi-family dwelling units (more than four units) located primarily in the Bank’s primary market area.  Multi-family loans are generally originated with variable rates of interest ranging from 1.00% to 3.50% over the one-year constant maturity U.S. Treasury Bill Index, the Prime Rate or a matched term FHLB borrowing, with principal and interest payments fully amortizing over terms of up to 30 years.  At September 30, 2020, the Bank’s largest multi-family loan had an outstanding principal balance of $7.20 million and was secured by an apartment building located in Thurston County. At September 30, 2020, this loan was performing according to its repayment terms.  

The maximum loan-to-value ratio for multi-family loans is generally limited to not more than 80%.  The Bank generally requests its multi-family loan borrowers with loan balances in excess of $750,000 to submit financial statements and rent rolls annually on the properties securing such loans.  The Bank also inspects such properties annually.  The Bank generally imposes a minimum debt coverage ratio of 1.20 for loans secured by multi-family properties.

Multi-family mortgage lending affords the Bank an opportunity to receive interest at rates higher than those generally available from one- to four- family residential lending.  However, loans secured by multi-family properties usually are greater in amount, more difficult to evaluate and monitor and, therefore, may involve a greater degree of risk than one- to four-family residential mortgage loans.  Because payments on loans secured by multi-family properties are often dependent on the successful operation and management of the properties, repayment of such loans may be affected by adverse conditions in the real estate market or the economy.  The Bank seeks to minimize these risks by scrutinizing the financial condition of the borrower, the quality of the collateral and the management of the property securing the loan.  If the borrower is other than an individual, the Bank also generally obtains personal guarantees from the principals (with ownership interests of 20% or more) based on a review of personal financial statements. At September 30, 2020, all multi-family loans were performing according to their repayment terms. See "Lending Activities - Non-performing Loans and Delinquencies."

Commercial Real Estate Lending.  Commercial real estate loans totaled $453.57 million, or 40.0%, of the total loan portfolio at September 30, 2020.  The Bank originates commercial real estate loans generally at variable interest rates with principal and interest payments fully amortizing over terms of up to 30 years.  These loans are secured by properties, such as office buildings, retail/wholesale facilities, mini-storage facilities, motels, nursing homes, restaurants and convenience stores, generally located in the Bank’s primary market area.  At September 30, 2020, the largest commercial real estate loan was secured by a medical building in Pierce County, had a balance of $7.82 million and was performing according to its repayment terms.  At September 30, 2020, four commercial real estate loans totaling $858,000 were on non-accrual status.  See “Lending Activities - Non-performing Loans and Delinquencies.”

The Bank typically requires appraisals of properties securing commercial real estate loans.  For loans that are less than $250,000, the Bank may use an evaluation provided by a third party vendor in lieu of an appraisal.  Appraisals are performed by independent appraisers designated by the Bank.  The Bank considers the quality and location of the real estate, the credit history of the borrower, the cash flow of the project and the quality of management involved with the property when making these loans.  The Bank generally imposes a minimum debt coverage ratio of approximately 1.20 for loans secured by income producing commercial properties.  Loan-to-value ratios on commercial real estate loans are generally limited to not more than 80%.  If the borrower is other than an individual, the Bank also generally obtains personal guarantees from the principals (with ownership interests of 20% or more) based on a review of personal financial statements.

Commercial real estate lending affords the Bank an opportunity to receive interest at rates higher than those generally available from one- to four-family residential lending.  However, loans secured by such properties usually are greater in amount, more difficult to evaluate and monitor and, therefore, involve a greater degree of risk than one- to four-family residential mortgage loans.  Because payments on loans secured by commercial properties often depend upon the successful operation and management of the properties, repayment of these loans may be affected by adverse conditions in the real estate market or the economy.  The Bank seeks to minimize these risks by generally limiting the maximum loan-to-value ratio to 80% and scrutinizing the financial condition of the borrower, the quality of the collateral and the management of the property securing the loan.  The Bank also generally requests annual financial information and rent rolls on the subject property from the borrowers on loans over $750,000.

Construction Lending.      The Bank currently originates two types of residential construction loans:  (i) custom construction and owner/builder construction loans and (ii) speculative construction loans.  The Bank believes that its lengthy experience in providing residential construction loans has enabled it to establish processing and disbursement procedures to meet the needs of its borrowers while reducing many of the risks inherent with construction lending.  The Bank also originates

9

construction loans for multi-family properties, commercial properties, and land development projects.  The Bank's construction loans generally provide for the payment of interest only during the construction phase, which is billed monthly, although during the term of some construction loans no payment from the borrower is required since the accumulated interest is added to the principal of the loan through an interest reserve. At September 30, 2020, the Bank's construction loans totaled $219.50 million, or 19.4% of the Bank's total loan portfolio, including undisbursed loans in process of $100.56 million. All construction loans were performing according to their repayment terms at September 30, 2020. See "Lending Activities - Non-performing Loans and Delinquencies."

At September 30, 2020 and 2019, the composition of the Bank’s construction loan portfolio was as follows:

	At September 30,
	2020				2019
	Outstanding Balance		Percent of Total		Outstanding Balance		Percent of Total

Total	$	219,496	100.00	%	$	223,526	100.00	%

Custom and owner/builder construction loans are originated to home owners and are typically converted to or refinanced into permanent loans at the completion of construction.  The construction phase of these loans generally lasts up to 12 months with fixed interest rates typically ranging from 4.50% to 6.50% and with loan-to-value ratios of 80% (or up to 95% with PMI) of the appraised estimated value of the completed property.  At the completion of construction, the loan is converted to or refinanced into either a fixed-rate mortgage loan, which conforms to secondary market standards, or an ARM loan for retention in the Bank’s portfolio.  At September 30, 2020, custom and owner/builder construction loans totaled $129.57 million, or 59.0% of the total construction loan portfolio.  At September 30, 2020, the largest outstanding custom and owner/builder construction loan had an outstanding balance of $6.60 million (including $53,000 of undisbursed loans in process) and was performing according to its repayment terms.

Speculative one- to four-family construction loans are made to home builders and are termed “speculative” because the home builder does not have, at the time of loan origination, a signed contract with a home buyer who has a commitment for permanent financing with either the Bank or another lender for the finished home.  The home buyer may be identified either during or after the construction period, with the risk that the builder will have to debt service the speculative construction loan and pay real estate taxes and other carrying costs of the completed home for a significant time after the completion of construction until the home buyer is identified and a sale is consummated.  Rather than originating lines of credit to home builders to construct several homes at once, the Bank generally originates and underwrites a separate loan for each home.  Speculative construction loans are generally originated for a term of 12 months, with current rates generally ranging from 5.00% to 6.50%, and with a loan-to-value ratio of no more than 80% of the appraised value of the completed property.  At September 30, 2020, speculative one- to four-family construction loans totaled $14.59 million, or 6.7% of the total construction loan portfolio.  At September 30, 2020, the largest aggregate outstanding balance to one borrower for speculative one- to four-family construction loans totaled $3.05 million (including $2.18 million of undisbursed loans in process) and was comprised of eleven loans that were performing according to their repayment terms.  

The Bank also provides construction financing for multi-family and commercial properties.  At September 30, 2020, these loans amounted to $67.62 million, or 30.8%, of construction loan balances compared to $75.83 million, or 33.9%, of construction loan balances at September 30, 2019.  These loans are typically secured by apartment buildings, condominiums, mini-storage facilities, office buildings, hotels and retail rental space predominantly located in the Bank’s primary market area.  At September 30, 2020, the largest outstanding multi-family construction loan for $8.03 million was secured by an apartment building project in Thurston County which had not yet commenced construction.  At September 30, 2020, the largest outstanding commercial real estate construction loan was secured by an assisted living facility project in Salem, Oregon and had a balance of $5.31 million with no remaining undisbursed funds available. This loan was performing according to its repayment terms at September 30, 2020.

All construction loans must be approved by a member of one of the Bank’s Loan Committees or the Bank’s Board of Directors, or in the case of one- to four-family construction loans that meet Freddie Mac guidelines, by the Regional Manager of Community Lending, the Loan Department Supervisor or a Bank underwriter. See “- Lending Activities - Loan Solicitation

and Processing.”  Prior to approval of any construction loan application, an independent fee appraiser inspects the site and prepares an appraisal on an "as completed" basis and the Bank reviews the existing or proposed improvements, identifies the market for the proposed project and analyzes the pro-forma data and assumptions on the project.  In the case of a speculative or custom construction loan, the Bank reviews the experience and expertise of the builder.  After this preliminary review, the application is processed, which includes obtaining credit reports, financial statements and tax returns or verification of income on the borrowers and guarantors, an independent appraisal of the project, and any other expert reports necessary to evaluate the proposed project.  In the event of cost overruns, the Bank generally requires that the borrower increase the funds available for construction by paying the cost of such overruns directly or by depositing its own funds into a secured savings account, the proceeds of which are used to pay construction costs, or to the extent available authorizes disbursements from a loan contingency line in the construction budget.

Loan disbursements during the construction period are made to the builder, materials supplier or subcontractor, based on a line item budget.  Periodic on-site inspections are made by qualified independent inspectors to document the reasonableness of draw requests.  For most builders, the Bank disburses loan funds by providing vouchers to borrowers, which when used by the borrower to purchase supplies are submitted by the supplier to the Bank for payment.

The Bank originates construction loan applications primarily through customer referrals, contacts in the business community and occasionally real estate brokers seeking financing for their clients.

Construction lending affords the Bank the opportunity to achieve higher interest rates and fees with shorter terms to maturity than does its single-family permanent mortgage lending.  Construction lending, however, is generally considered to involve a higher degree of risk than single-family permanent mortgage lending because funds are advanced upon the collateral for the project based on an estimate of the costs that will produce a future value at completion. Because of the uncertainties inherent in estimating construction costs, as well as the market value of the completed project and the effects of governmental regulation on real property, it is relatively difficult to evaluate accurately the total funds required to complete a project and the completed project loan-to-value ratio.  With regard to loans originated to builders for speculative projects, changes in the demand, such as for new housing and higher than anticipated building costs, may cause actual results to vary significantly from those estimated. A downturn in the housing, or the real estate market, could increase loan delinquencies, defaults, and foreclosures, and significantly impair the value of our collateral and our ability to sell the collateral upon foreclosure. Some builders who have borrowed from us to fund construction projects on a speculative basis have more than one loan outstanding with us. Consequently, an adverse development with respect to one loan or one credit relationship can expose us to a significantly greater risk of loss.

In addition, during the term of many of our construction loans granted to builders who are building residential units for sale, no payment from the borrower is required since the accumulated interest is added to the principal of the loan through an interest reserve. As a result, these loans often involve the disbursement of funds with repayment substantially dependent on the success of the ultimate project and the ability of the borrower to sell or lease the property or obtain permanent take-out financing, rather than the ability of the borrower or guarantor to repay principal and interest. If our appraisal of the value of a completed project proves to be overstated, we may have inadequate security for the repayment of the loan upon completion of construction of the project and may incur a loss. Because construction loans require active monitoring of the building process, including cost comparisons and on-site inspections, these loans are more difficult and costly to monitor. Increases in market rates of interest may have a more pronounced effect on construction loans by rapidly increasing the end-purchasers' borrowing costs, thereby reducing the overall demand for the project. Properties under construction are often difficult to sell and typically must be completed in order to be successfully sold which also complicates the process of working out problem construction loans. This may require us to advance additional funds and/or contract with another builder to complete construction. Furthermore, in the case of speculative construction loans, there is an added risk associated with identifying an end-purchaser for the finished project.

The Bank historically originated loans to real estate developers with whom it had established relationships for the purpose of developing residential subdivisions (i.e., installing roads, sewers, water and other utilities; generally with ten to 50 lots). At September 30, 2020, land development loans totaled $7.71 million, or 3.5% of the total construction loan portfolio. Currently, the Bank is originating land development loans on a limited basis.  Land development loans are secured by a lien on the property and typically are made for a period of two to five years with fixed or variable interest rates, with loan-to-value ratios generally not exceeding 75%.  Land development loans are generally structured so that the Bank is repaid in full upon the sale by the borrower of approximately 80% of the subdivision lots.  In addition, in the case of a corporate borrower, the Bank also generally obtains personal guarantees from corporate principals (with ownership interests in the borrowing entity of 20% or more) and reviews their personal financial statements. Land development loans secured by land under development involve greater risks than one- to four-family residential mortgage loans because these loan funds are advanced upon the predicted future value of the developed property upon completion.  If the estimate of the future value proves to be inaccurate, in the event of default and foreclosure the Bank may be confronted with a property the value of which is insufficient to assure full

11

repayment.  The Bank has historically attempted to minimize this risk by generally limiting the maximum loan-to-value ratio on land and land development loans to 75% of the estimated developed value of the secured property.  

Land Lending. The Bank originates loans for the acquisition of land upon which the purchaser can then build or make improvements necessary to build or to use for recreational purposes.  At September 30, 2020, land loans totaled $25.57 million, or 2.3%, of the Bank’s total loan portfolio.  Land loans originated by the Bank generally have maturities of one to ten years.  The largest land loan is secured by land in Clark County, had an outstanding balance of $1.70 million and was performing according to its repayment terms at September 30, 2020.  At September 30, 2020, three land loans totaling $394,000 were on non-accrual status.  See “Lending Activities - Non-performing Loans and Delinquencies.”

Loans secured by undeveloped land or improved lots involve greater risks than one- to four-family residential mortgage loans because these loans are more difficult to evaluate.  If the estimate of value proves to be inaccurate, in the event of default and foreclosure the Bank may be confronted with a property the value of which is insufficient to assure full repayment. Land loans also pose additional risk because of the lack of income being produced by the property and potential illiquid nature of the collateral. These risks can be significantly impacted by supply and demand conditions.  The Bank attempts to minimize these risks by generally limiting the maximum loan-to-value ratio on land loans to 75%.

Consumer Lending.  Consumer loans generally have shorter terms to maturity and may have higher interest rates than mortgage loans.  Consumer loans include home equity lines of credit, second mortgage loans, savings account loans, automobile loans, boat loans, motorcycle loans, recreational vehicle loans and unsecured loans.  Consumer loans are made with both fixed and variable interest rates and with varying terms.  At September 30, 2020, consumer loans amounted to $35.65 million, or 3.1%, of the Bank's total loan portfolio.

At September 30, 2020, the largest component of the consumer loan portfolio consisted of second mortgage loans and home equity lines of credit, which totaled $32.08 million, or 2.8%, of the Bank's total loan portfolio.  Home equity lines of credit and second mortgage loans are made for purposes such as the improvement of residential properties, debt consolidation and education expenses, among others.  The majority of these loans are made to existing customers and are secured by a first or second mortgage on residential property.  The loan-to-value ratio is typically 90% or less, when taking into account both the first and second mortgage loans.  Second mortgage loans typically carry fixed interest rates with a fixed payment over a term between five and 15 years.  Home equity lines of credit are generally made at interest rates tied to the Prime Rate.  Second mortgage loans and home equity lines of credit have greater credit risk than one- to four-family residential mortgage loans in which the Bank is in the first lien position because they are generally secured by mortgages subordinated to the existing first mortgage on the property. For those second mortgage loans and home equity lines credit which the Bank does not hold the existing first mortgage on the property, it is unlikely that the Bank will be successful in recovering all or a portion of the loan balance in the event of default unless the Bank is prepared to repay the first mortgage loan and such repayment and the costs associated with a foreclosure are justified by the value of the property.

Consumer loans entail greater risk than do residential mortgage loans, particularly in the case of consumer loans that are unsecured or secured by rapidly depreciating assets such as automobiles.  In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation.  The remaining deficiency often does not warrant further substantial collection efforts against the borrower beyond obtaining a deficiency judgment.  In addition, consumer loan collections are dependent on the borrower’s continuing financial stability and are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy.  Furthermore, the application of various federal and state laws, including federal and state bankruptcy and insolvency laws, may limit the amount that can be recovered on such loans.  The Bank believes that these risks are not as prevalent in the case of the Bank’s consumer loan portfolio because a large percentage of the portfolio consists of second mortgage loans and home equity lines of credit that are underwritten in a manner such that they result in credit risk that is substantially similar to one- to four-family residential mortgage loans.  At September 30, 2020, seven consumer loans totaling $564,000 were on non-accrual status. See “Lending Activities - Non-performing Loans and Delinquencies.”

Commercial Business Lending.  Commercial business loans (excluding SBA PPP loans) totaled $69.54 million, or 6.1%, of the loan portfolio at September 30, 2020.  Commercial business loans are generally secured by business equipment, accounts receivable, inventory and/or other property and are made at variable rates of interest equal to a negotiated margin above the Prime Rate.  The Bank also generally obtains personal guarantees from the principals based on a review of personal financial statements. The largest commercial business loan had an outstanding balance of $2.33 million at September 30, 2020 and was performing according to its repayment terms.  At September 30, 2020, six commercial business loans totaling $430,000 were on non-accrual status.  See “Lending Activities - Non-performing Loans and Delinquencies.”    

The Bank has increased commercial business loan originations made under the U.S. Small Business Administration ("SBA") 7(a) program. Loans made by the Bank under the SBA 7(a) program generally are made to small businesses to

12

provide working capital or to provide funding for the purchase of businesses, real estate, or equipment. These loans generally are secured by a combination of assets that may include equipment, receivables, inventory, business real property, and sometimes a lien on the personal residence of the borrower. The terms of these loans vary by purpose and type of underlying collateral. The loans are primarily underwritten on the basis of the borrower's ability to service the loan from income. Under the SBA 7(a) program the loans carry a SBA guaranty for up to 85% of the loan. Typical maturities for this type of loan vary but can be up to ten years. SBA 7(a) loans are all adjustable rate loans based on the Prime Rate. Under the SBA 7(a) program, the Bank can sell in the secondary market the guaranteed portion of its SBA 7(a) loans and retain the related unguaranteed portion of these loans, as well as the servicing on such loans, for which it is paid a fee. The loan servicing spread is generally a minimum of 1.00% on all SBA 7(a) loans. The Bank generally offers SBA 7(a) loans within a range of $50,000 to $1.50 million.

Within Timberland's commercial business loan portfolio are restaurant loans totaling $16.82 million at September 30, 2020 that were originated in conjunction with a third party firm. As additional security for these loans, the Company holds cash collateral of 25% of the outstanding loan balance. Unless prior arrangements are made, and the Company consents, loans falling more than four weeks delinquent are eligible for purchase in accordance with a Marketing and Servicing Agreement in existence since March 6, 2014. As an accommodation, the Company has agreed to temporarily extend the purchase requirement to 12 weeks before a purchase is required from the loan portfolio.

Commercial business lending generally involves greater risk than residential mortgage lending and involves risks that are different from those associated with residential and commercial real estate lending.  Real estate lending is generally considered to be collateral based lending with loan amounts based on predetermined loan to collateral values, and liquidation of the underlying real estate collateral is viewed as the primary source of repayment in the event of borrower default.  Although commercial business loans are often collateralized by equipment, inventory, accounts receivable and/or other business assets, the liquidation of collateral in the event of a borrower default is often an insufficient source of repayment because accounts receivable may be uncollectible and inventories and equipment may be obsolete or of limited use, among other things.  Accordingly, the repayment of a commercial business loan depends primarily on the creditworthiness of the borrower (and any guarantors), while liquidation of collateral is a secondary and often insufficient source of repayment.

SBA PPP Lending. The CARES Act authorized the SBA to temporarily guarantee loans under a new loan program called the Paycheck Protection Program. As a qualified SBA lender, the Company was automatically authorized to originate PPP loans upon commencement of the program in April 2020 through its conclusion on August 8, 2020. PPP loans have: (a) an interest rate of 1.0%, (b) a two-year loan term to maturity for loans approved by the SBA prior to June 5, 2020 and a five-year maturity for loans approved thereafter, and (c) principal and interest payments deferred for at least six months from the date of disbursement. The SBA guarantees 100% of the PPP loans made to eligible borrowers. The entire principal amount of the borrower's PPP loan, including any accrued interest, is eligible to be forgiven and repaid by the SBA. SBA PPP loans totaled $126.82 million, or 11.2% of the loan portfolio at September 30, 2020. The largest SBA PPP loan had an outstanding balance of $4.56 million at September 30, 2020.

Loan Maturity.  The following table sets forth certain information at September 30, 2020 regarding the dollar amount of loans maturing in the Bank’s portfolio based on their contractual terms to maturity but does not include scheduled payments or potential prepayments.  Loans having no stated maturity and overdrafts are reported as due in one year or less.

Scheduled contractual principal repayments of loans do not reflect the actual life of these assets.  The average life of loans is substantially less than their contractual terms because of prepayments.  In addition, due-on-sale clauses on loans generally give the Bank the right to declare loans immediately due and payable in the event, among other things, that the borrower sells the real property subject to the mortgage and the loan is not repaid.  The average life of mortgage loans tends to increase when current mortgage loan interest rates are substantially higher than interest rates on existing mortgage loans and, conversely, decrease when interest rates on existing mortgage loans are substantially higher than current mortgage loan interest rates.

Loan Solicitation and Processing.  Loan originations are obtained from a variety of sources, including walk-in customers and referrals from builders and realtors.  Upon receipt of a loan application from a prospective borrower, a credit report and other data are obtained to verify specific information relating to the loan applicant’s employment, income and credit

14

standing.  An appraisal of the real estate offered as collateral generally is undertaken by a certified appraiser retained by the Bank.

Loan applications are initiated by loan officers and are required to be approved by an authorized loan officer or Bank underwriter, one of the Bank’s Loan Committees or the Bank’s Board of Directors.  The Bank’s Consumer Loan Committee consists of several underwriters, each of whom can approve one- to four-family mortgage loans and other consumer loans up to and including the current Freddie Mac single-family limit. Loan officers may also be granted individual approval authority for certain loans up to a maximum of $250,000. The approval authority for individual loan officers is granted on a case by case basis by the Bank's Chief Credit Administrator or President.  All construction loans must be approved by a member of one of the Bank's Loan Committees or the Bank's Board of Directors, or in the case of one- to four- family construction loans that meet Freddie Mac guidelines, by the Regional Manager of Community Lending, the Loan Department Supervisor or a Bank underwriter, subject to their individual or Loan Committee loan limit. The Bank’s Commercial Loan Committee, which consists of the Bank’s President, Chief Credit Administrator, Executive Vice President of Lending, a commercial underwriter, and two Senior Vice Presidents of Commercial Lending, may approve commercial real estate loans and commercial business loans up to and including $3.00 million. The Bank’s President, Chief Credit Administrator and Executive Vice President of Lending also have individual lending authority for loans up to and including $750,000. The Bank’s Board Loan Committee, which consists of two rotating non-employee Directors and the Bank’s President, may approve loans up to and including $5.00 million.  Loans in excess of $5.00 million, as well as loans of any amount granted to a single borrower whose aggregate loans exceed $5.00 million, must be approved by the Bank’s Board of Directors.

Loan Originations, Purchases and Sales.  During the years ended September 30, 2020, 2019 and 2018, the Bank’s total gross loan originations were $597.19 million, $356.04 million and $329.59 million, respectively.  Periodically, the Bank purchases loan participation interests in construction, commercial real estate and multi-family loans, secured by properties generally located in Washington State, from other banks.  These participation loans are underwritten in accordance with the Bank’s underwriting guidelines and are without recourse to the seller other than for fraud.  During the years ended September 30, 2020, the Bank did not purchase any loan participation interests. During the years ended September 30, 2019 and 2018, the Bank purchased loan participation interests of $8.66 million and $8.40 million, respectively. 

Consistent with its asset/liability management strategy, the Bank’s policy generally is to retain in its portfolio all ARM loans originated and to sell fixed rate one- to four-family mortgage loans in the secondary market to Freddie Mac; however, from time to time, a portion of fixed-rate loans may be retained in the Bank’s portfolio to meet its asset-liability objectives. The Bank also began selling the guaranteed portion of some of its SBA 7(a) loans in the secondary market during the year ended September 30, 2016.  Loans sold in the secondary market are generally sold on a servicing retained basis.  At September 30, 2020, the Bank’s loan servicing portfolio, which is not included in the Company’s consolidated financial statements, totaled $426.58 million.

The Bank also periodically sells participation interests in construction loans, commercial real estate loans, multi-family and commercial business loans to other lenders.  These sales are usually made to avoid concentrations in a particular loan type or concentrations to a particular borrower and to generate fee income.  During the years ended September 30, 2020, 2019 and 2018, the Bank sold loan participation interests of $6.26 million, $5.43 million and $253,000, respectively.

Loan Origination Fees.  The Bank receives loan origination fees on many of its mortgage loans and commercial business loans.  Loan fees are a percentage of the loan which are charged to the borrower for funding the loan.  The amount of fees charged by the Bank (excluding SBA PPP loans) is generally up to 2.0% of the loan amount. In addition to the 1.0% interest earned on SBA PPP loans, the SBA pays bank fees for processing PPP loans in the following amounts: (i) five percent of loans of not more than $350,000; (ii) three percent for loans more than $350,000 and less than $2,000,000; and (iii) one percent of loans of at least $2,000,000. Banks may not collect any fees from the SBA PPP loan applicants.

  Accounting principles generally accepted in the United States of America ("GAAP") require fees received and certain loan origination costs for originating loans to be deferred and amortized into interest income over the contractual life of the loan.  Net deferred fees or costs associated with loans that are prepaid are recognized as income/expense at the time of prepayment.  Unamortized net deferred loan origination fees totaled $6.44 million (including $3.72 million for SBA PPP loans) at September 30, 2020.

Non-performing Loans and Delinquencies.  The Bank assesses late fees or penalty charges on delinquent loans of approximately 5% of the monthly loan payment amount.  A majority of loan payments are due on the first day of the month; however, the borrower is given a 15 day grace period to make the loan payment.  When a mortgage loan borrower fails to make

16

a required payment when due, the Bank institutes collection procedures. A notice is mailed to the borrower 16 days after the date the payment is due.  Attempts to contact the borrower by telephone generally begin on or before the 30th day of delinquency.  If a satisfactory response is not obtained, continuous follow-up contacts are attempted until the loan has been brought current.  Before the 90th day of delinquency, attempts are made to establish (i) the cause of the delinquency, (ii) whether the cause is temporary, (iii) the attitude of the borrower toward repaying the debt, and (iv) a mutually satisfactory arrangement for curing the default.

If the borrower is chronically delinquent and all reasonable means of obtaining payment on time have been exhausted, foreclosure is initiated according to the terms of the security instrument and applicable law.  Interest income on loans in foreclosure is reduced by the full amount of accrued and uncollected interest.

When a consumer loan borrower or commercial business borrower fails to make a required payment on a loan by the payment due date, the Bank institutes similar collection procedures as for its mortgage loan borrowers.  All loans becoming 90 days or more past due are placed on non-accrual status, with any accrued interest reversed against interest income, unless they are well secured and in the process of collection.

The Bank’s Board of Directors is updated monthly as to the status of loans that are delinquent by more than 30 days and the status of all foreclosed and repossessed property owned by the Bank.

In late March 2020, the Bank announced loan modification programs to support and provide relief for its borrowers during the COVID-19 pandemic. Loans subject to payment forbearance under the Bank's COVID-19 loan modification program are not reported as delinquent during the forbearance time period. For additional information, see "COVID-19 Loan Modifications" below>

_______________

(1)Includes non-accrual one- to four-family properties in the process of foreclosure totaling $0, $150,

$0, $100 and $138 as of September 30, 2020, 2019, 2018, 2017 and 2016, respectively.

(2)Includes foreclosed residential real estate property totaling $0, $0, $0, $875 and $1,071

as of September 30, 2020, 2019, 2018, 2017 and 2016, respectively.

(3)Does not include troubled debt restructured loans on accrual status.

(4)Does not include troubled debt restructured loans totaling $203, $366, $323, $253 and $531

recorded as non-accrual loans as of September 30, 2020, 2019, 2018, 2017 and 2016, respectively.

(5)Loans receivable, net for this table includes the deductions for the undisbursed portion of construction loans in process

and deferred loan origination fees and does not include the deduction for the allowance for loan losses.

The Bank’s non-accrual loans decreased by $128,000 to $2.91 million at September 30, 2020 from $3.03 million at September 30, 2019, primarily as a result of a $295,000 decrease in commercial business loans, a $62,000 decrease in consumer loans, and a $40,000 decrease in one- to four-family mortgage loans, on non-accrual status. These decreases were partially offset by a $190,000 increase in land loans and a $79,000 increase on commercial real estate loans on non-accrual status.  A discussion of the Bank's largest non-performing loans is set forth below under “Asset Classification.”

Additional interest income which would have been recorded for the year ended September 30, 2020 had non-accruing loans been current in accordance with their original terms totaled $574,000.

Other Real Estate Owned and Other Repossessed Assets.  Real estate acquired by the Bank as a result of foreclosure or by deed-in-lieu of foreclosure is classified as other real estate owned (“OREO”) until sold.  When property is acquired, it is recorded at the estimated fair market value less estimated costs to sell.  At September 30, 2020, the Bank had $1.05 million of OREO and other repossessed assets, a decrease of $633,000 from $1.68 million at September 30, 2019.  The OREO properties consisted of six land parcels totaling $1.05 million at September 30, 2020.  The largest OREO property at September 30, 2020 was an undeveloped land parcel with a balance of $702,000 located in Lewis County.

Restructured Loans.  Under GAAP, the Bank is required to account for certain loan modifications or restructurings as “troubled debt restructurings” or "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 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. TDRs are considered impaired and are individually evaluated for impairment. TDRs are classified as either accrual or non-accrual. TDRs are classified as non-performing loans unless they have been performing in accordance with their modified terms for a period of at least six months. The Bank had TDRs at September 30, 2020 and 2019 totaling $3.07 million and $3.27 million, respectively, of which $203,000 and $366,000, respectively, were on non-accrual status. The allowance for loan losses allocated to TDR loans at September 30, 2020 and 2019 was $3,000 and $56,000, respectively. As previously noted, in late March 2020, the Bank announced COVID-19 loan modification programs to support and provide relief for its borrowers during the COVID-19 pandemic. The Company has followed the CARES Act and interagency guidance from the federal banking agencies when determining if a borrower's modification is subject to TDR classification. See "COVID-19 Loan Modifications" below.

Impaired Loans. In accordance with GAAP, a loan is considered impaired when based on current information and events 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.

18

The categories of non-accrual loans and impaired loans overlap, although they are not identical.  The Bank considers all circumstances regarding the loan and borrower on an individual basis when determining whether an impaired loan should be placed on non-accrual status, such as the financial strength of the borrower, the collateral value, reasons for delay, payment record, the amount past due and the number of days past due.  At September 30, 2020, the Bank had $5.77 million in impaired loans.  For additional information on impaired loans, see Note 5 of the Notes to the Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

Other Loans of Concern.  Loans not reflected in the table above as non-performing, but where known information about possible credit problems of borrowers causes management to have doubts as to the ability of the borrower to comply with present repayment terms and that may result in disclosure of such loans as non-performing assets in the future, are commonly referred to as “other loans of concern” or “potential problem loans.”  The amount included in potential problem loans results from an evaluation, on a loan-by-loan basis, of loans classified as “substandard” and “special mention,” as those terms are defined under “Asset Classification” below.  The amount of potential problem loans (not included in the table above as non-performing) was $6.61 million at September 30, 2020. The vast majority of these loans are collateralized by real estate.  See “Asset Classification” below for additional information regarding the Bank's problem loans.

COVID-19 Loan Modifications. The CARES Act provided guidance around the modification of loans as a result of the COVID-19 pandemic, which outlined, among other criteria, that short-term modifications made on a good faith basis to borrowers who were current as defined under the CARES Act prior to any relief, are not TDRs. This includes short-term modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. Borrowers are considered current under the CARES Act and related regulatory guidance if they are less than 30 days past due on their contractual payments at the time a modification program is implemented. During the year ended September 30, 2020, the Company made COVID-19 pandemic related modifications on 212 loans aggregating to $136.36 million. The majority of these borrowers had resumed making payments as of September 30, 2020 and only five loans totaling $5.87 million remained on deferral status as of that date. Loan modifications in accordance with the CARES Act and related regulatory guidance are still subject to an evaluation in regard to determining whether or not a loan is deemed to be impaired. See Note 1 and Note 5 of the Notes to the Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for additional information.

The following table sets forth the information with respect to loans still on COVID-19 modification status as of September 30, 2020 (dollars in thousands):

Asset Classification.  Applicable regulations require that each insured institution review and classify its assets on a regular basis.  In addition, in connection with examinations of insured institutions, regulatory examiners have authority to identify problem assets and, if appropriate, require them to be classified.  There are three classifications for problem assets:  substandard, doubtful and loss.  Substandard loans are classified as those loans that are inadequately protected by the current net worth and paying capacity of the obligor, or of the collateral pledged.  Assets classified as substandard have a well-defined weakness or weaknesses that jeopardize the repayment of the debt.  If the weakness or weaknesses are not corrected there is the distinct possibility that some loss will be sustained.  Doubtful assets have the weaknesses of substandard assets with the additional characteristic that the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions and values questionable, and there is a high possibility of loss.  An asset classified as loss is considered uncollectible and of such little value that continuance as an asset of the Bank is not warranted.  When the Bank classifies problem assets as either substandard or doubtful, it is required to establish allowances for loan losses in an amount deemed prudent by management.  These allowances represent loss allowances which have been established to recognize the inherent risk associated

19

with lending activities and the risks associated with particular problem assets.  When the Bank classifies problem assets as loss, it charges off the balance of the asset against the allowance for loan losses.  Assets which do not currently expose the Bank to sufficient risk to warrant classification in one of the aforementioned categories but possess weaknesses are designated by the Bank as special mention.  Special mention loans are defined as those credits deemed by management to have some potential weakness that deserve management’s close attention.  If left uncorrected, these potential weaknesses may result in the deterioration of the payment prospects of the loan.  Assets in this category are not adversely classified and currently do not expose the Bank to sufficient risk to warrant a substandard classification. The Bank’s determination of the classification of its assets and the amount of its valuation allowances is subject to review by the FDIC and the Division which can require a different classification and the establishment of additional loss allowances.

The aggregate amounts of the Bank’s classified and special mention loans (as determined by the Bank), and the allowance for loan losses at the dates indicated, were as follows:

	At September 30,
	2020		2019		2018

(2)Includes non-performing loans.

Loans classified as substandard decreased by $1.67 million to $3.65 million at September 30, 2020 from $5.32 million at September 30, 2019.  At September 30, 2020, 33 loans were classified as substandard. Of the $3.65 million in loans classified as substandard at September 30, 2020, $2.91 million were on non-accrual status.  The largest loan classified as substandard at September 30, 2020 had a balance of $391,000 and was secured by a commercial real estate property in Grays Harbor County and equipment. This loan was on non-accrual status at September 30, 2020.  The next largest loan classified as substandard at September 30, 2020 had a balance of $346,000 and was secured by a single family home in Pierce County. This loan was performing according to its payment terms at September 30, 2020.

Loans classified as special mention increased by $3.32 million to $5.86 million at September 30, 2020 from $2.55 million at September 30, 2019, primarily as a result of two participation loans being downgraded to special mention status. At September 30, 2020, nine loans were classified as special mention. The largest loan classified as special mention at September 30, 2020 had a balance of $2.88 million and was secured by a hotel in Clackamas County, Oregon. The next largest loan classified as special mention at September 30, 2020 had a balance of $1.40 million and was secured by the same hotel in Clackamas County, Oregon. Both of these loans were subject to COVID-19 related loan modification agreements at September 30, 2020.

Allowance for Loan Losses.  The allowance for loan losses is maintained to absorb probable losses inherent in the loan portfolio.  The Bank has established a comprehensive methodology for the determination of provisions for loan losses that takes into consideration the need for an overall general valuation allowance.  The Bank’s methodology for assessing the adequacy of its allowance for loan losses is based on its historic loss experience for various loan segments; adjusted for changes in economic conditions, delinquency rates and other factors.  Using these loss estimate factors, management develops a range of probable loss for each loan category.  Certain individual loans for which full collectibility may not be assured are evaluated individually with loss exposure based on estimated discounted cash flows or net realizable collateral values.  The total estimated range of loss based on these two components of the analysis is compared to the loan loss allowance balance.  When determining the appropriate loss factors in fiscal 2020, management took into consideration the impact of the COVID-19 pandemic on such factors as the national and state unemployment rates and related trends, the amount of and timing of financial assistance provided by the government, consumer spending levels and trends, industries significantly impacted by the COVID-19 pandemic, and the Bank's COVID-19 loan modification program.

20

Based on this review, management increased the qualitative factors for all loan categories due to deterioration of economic conditions as a result of the COVID-19 pandemic. The increase in factors resulted in an increase in the allowance for loan losses during the current fiscal year. Management will continue to closely monitor economic conditions and will work with borrowers as necessary to assist them through this challenging economic climate. If economic conditions worsen or do not improve in the near term, and if future government programs, if any, do not provide adequate relief to borrowers, it is possible the Bank's allowance for loan losses will need to increase in future periods.

In originating loans, the Bank recognizes that losses will be experienced and that the risk of loss will vary with, among other things, the type of loan being made, the creditworthiness of the borrower over the term of the loan, general economic conditions and, in the case of a secured loan, the quality of the security for the loan.  The Bank increases its allowance for loan losses by charging provisions for loan losses against the Bank's operating income.

The Board of Directors reviews the adequacy of the allowance for loan losses at least quarterly based on management's assessment of current economic conditions, past loss and collection experience, and risk characteristics of the loan portfolio.

At September 30, 2020, the Bank’s allowance for loan losses totaled $13.41 million.  The Bank’s allowance for loan losses as a percentage of total loans receivable and non-performing loans was 1.31% and 461.76%, respectively, at September 30, 2020 and 1.08% and 319.49%, respectively, at September 30, 2019. The increase in the allowance for loan losses during the year ended September 30, 2020 was primarily due to the deteriorating economic conditions and probable loan losses driven by the impact of the COVID-19 pandemic on the U.S. and global economies. The $126.82 million balance of SBA PPP loans was omitted from the allowance for loan loss calculation at September 30, 2020 as these loans are fully guaranteed by the SBA and management expects that the great majority of PPP borrowers will seek full or partial forgiveness of their loan obligations from the SBA within a short time frame, which will in turn reimburse the Bank for the amount forgiven.

In accordance with GAAP, loans acquired in the South Sound Acquisition were recorded at their estimated fair value, which resulted in a net discount to the loan's contractual amount, of which a portion reflects a discount for possible credit losses. Credit discounts are included in the determination of fair value and as a result no allowance for loans losses is recorded for acquired loans at the acquisition date. The discount recorded on acquired loans is not reflected in the allowance for loan losses or the related allowance coverage ratios, however we believe it should be considered when comparing the current ratios to similar ratios in periods prior to the South Sound Acquisition. The remaining fair value discount on loans acquired in the South Sound Acquisition was $790,000 at September 30, 2020.

Based on its comprehensive analysis, management believes that the amount maintained in the allowance for loan losses is adequate to absorb probable losses inherent in the portfolio. Although management believes that it uses the best information available to make its determinations, future adjustments to the allowance for loan losses may be necessary, and results of operations could be significantly and adversely affected if circumstances differ substantially from the assumptions used in making the determinations.

While the Bank believes it has established its existing allowance for loan losses in accordance with GAAP, there can be no assurance that regulators, in reviewing the Bank's loan portfolio, will not request the Bank to increase significantly its allowance for loan losses.  In addition, because future events affecting borrowers and collateral cannot be predicted with certainty, there can be no assurance that the existing allowance for loan losses is adequate or that substantial increases will not be necessary should the quality of any loans deteriorate.  A further decline in national and local economic conditions, as a result of the COVID-19 pandemic or other factors, could result in a material increase in the allowance for loan losses which may adversely affect the Company's financial condition and results of operations.

Investment Activities

The investment policies of the Bank are established and monitored by the Board of Directors.  The policies are designed primarily to provide and maintain liquidity, to generate a favorable return on investments without incurring undue interest rate and credit risk, and to compliment the Bank’s lending activities.  These policies dictate the criteria for classifying investments in debt securities as either available for sale or held to maturity.  The policies permit investment in various types of liquid assets permissible under applicable regulations, which include U.S. Treasury obligations, securities of various federal agencies, certificates of deposit of insured banks, federal funds, mortgage-backed securities, municipal bonds and mutual funds.  The Company's investment policy also permits investment in equity securities in certain financial service companies.

Investments in equity securities are stated at fair value. Prior to October 1, 2018, changes in the fair value of investments in equity securities were excluded from earnings and reported in other comprehensive income (loss), net of income tax effects. On October 1, 2018, the Company adopted ASU 2016-01 and reclassified its mutual funds as investments in equity securities. Beginning October 1, 2018, changes in the fair value of investments in equity securities are recorded in other non-interest income.

At September 30, 2020, the Bank’s portfolio of investments in debt securities totaled $85.80 million, consisting of $27.39 million of mortgage-backed securities held to maturity, $500,000 bank issued trust preferred securities held to maturity and $57.91 million of mortgage-backed securities available for sale.  The Bank does not maintain a trading account for any investments.  This compares with a total investment portfolio of $53.63 million at September 30, 2019, consisting of $3.00 million of U.S. Treasury and U.S. government agency securities held to maturity, $28.10 million of mortgage-backed securities held to maturity, and $22.53 million of mortgage-backed securities available for sale.  The composition of the portfolios by type of security at the dates indicated is presented in the following table:

There were no securities which had an aggregate book value in excess of 10% of the Bank’s total equity at September 30, 2020.  At September 30, 2020, the Bank had $229,000 of private label mortgage-backed securities in the held to maturity investment securities portfolio of which $209,000 were on non-accrual status.  For additional information regarding investment securities, see “Item 1A. Risk Factors – Our investment securities portfolio may be negatively impacted by fluctuations in market value and interest rates and result in losses” and Note 4 of the Notes to the Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K.

Deposit Activities and Other Sources of Funds

General.  Deposits and loan repayments are the major sources of the Bank's funds for lending and other investment purposes.  Scheduled loan repayments are a relatively stable source of funds, while deposit inflows and outflows and loan prepayments are influenced significantly by general interest rates and money market conditions.  Borrowings through the FHLB and the Federal Reserve Bank of San Francisco ("FRB") may be used to compensate for reductions in the availability of funds from other sources.

Deposit Accounts.  Substantially all of the Bank's depositors are residents of Washington.  Deposits are attracted from within the Bank's market area through the offering of a broad selection of deposit instruments, including money market deposit accounts, checking accounts, regular savings accounts and certificates of deposit.  Deposit account terms vary, according to the minimum balance required, the time periods the funds must remain on deposit and the interest rate, among other factors.  In determining the terms of its deposit accounts, the Bank considers current market interest rates, profitability to the Bank, matching deposit and loan products and its customer preferences and concerns.  The Bank actively seeks consumer and commercial checking accounts through checking account acquisition marketing programs. The Bank also has checking accounts owned by businesses associated with the marijuana (or Initiative-502) industry in Washington State. It is generally permissible in Washington State to handle accounts associated with this industry in compliance with federal regulatory guidelines.  At September 30, 2020, the Bank had $34.68 million, or 2.6% of total deposits, from businesses associated with the marijuana industry. See "Item 1A. Risk Factors - We operate in a highly regulated environment and may be adversely affected by changes in federal and state laws and regulations that could increase our costs of operations."

At September 30, 2020, the Bank had $28.95 million of jumbo certificates of deposit of $250,000 or more.  The Bank had $11.30 million in brokered reciprocal money market deposits at September 30, 2020. The Bank believes that its jumbo certificates of deposit, which represented 2.1% of total deposits at September 30, 2020, present similar interest rate risks as compared to its other deposits.

Borrowings.  Deposits and loan repayments are generally the primary source of funds for the Bank's lending and investment activities and for general business purposes.  The Bank has the ability to use borrowings from the FHLB to supplement its supply of lendable funds and to meet deposit withdrawal requirements.  The FHLB functions as a central reserve bank providing credit for member financial institutions.  As a member of the FHLB, the Bank is required to own capital stock in the FHLB and is authorized to apply for borrowings on the security of such stock and certain mortgage loans and other assets (principally securities which are obligations of, or guaranteed by, the U.S. government) provided certain creditworthiness standards have been met.  Borrowings are made pursuant to several different credit programs.  Each credit program has its own interest rate and range of maturities.  Depending on the program, limitations on the amount of borrowings are based on the financial condition of the member institution and the adequacy of collateral pledged to secure the credit. At September 30, 2020, the Bank maintained an uncommitted credit facility with the FHLB that provided for immediately available borrowings up to an aggregate amount to 45% of the Bank’s total assets, limited by available collateral, under which $10.0 million in borrowings were outstanding. The Bank maintains a short-term borrowing line of credit with the FRB with total credit based on eligible collateral.  At September 30, 2020, the Bank had no outstanding balance and $71.90 million in unused borrowing capacity on this borrowing line of credit. A short-term borrowing line of credit of $50.00 million is also maintained at Pacific Coast Bankers' Bank ("PCBB"). The Bank had no outstanding balance on this borrowing line of credit at September 30, 2020.

The following table sets forth certain information regarding borrowings, including repurchase agreements, by the Bank at the end of and during the periods indicated:

________________________

The Bank did not have any short-term borrowings for the years ended September 30, 2020, 2019 and 2018.

Bank Owned Life Insurance

The Bank has purchased life insurance policies covering certain officers.  These policies are recorded at their cash surrender value, net of any cash surrender charges.  Increases in cash surrender value, net of policy premiums, and proceeds from death benefits are recorded in non-interest income.  At September 30, 2020, the cash surrender value of bank owned life insurance (“BOLI”) was $21.60 million.

How We Are Regulated

General.  As a bank holding company, Timberland Bancorp is subject to examination and supervision by, and is required to file certain reports with, the Federal Reserve. Timberland Bancorp is also subject to the rules and regulations of the SEC under the federal securities laws. As a state-chartered savings bank, the Bank is subject to regulation and oversight by the Division and the applicable provisions of Washington law and regulations of the Division adopted thereunder.  The Bank also is subject to regulation and examination by the FDIC, which insures the deposits of the Bank to the maximum extent permitted by law, and requirements established by the Federal Reserve.  State law and regulations govern the Bank's ability to take deposits

27

and pay interest thereon, to make loans on or invest in residential and other real estate, to make consumer loans, to invest in securities, to offer various banking services to its customers and to establish branch offices.  Under state law, savings banks in Washington also generally have all of the powers that federal savings banks have under federal laws and regulations.  The Bank is subject to periodic examination and reporting requirements by and of the Division and the FDIC. The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act") established the Consumer Financial Protection Bureau ("CFPB") as an independent bureau of the Federal Reserve with responsibility for the implementation of federal financial consumer protection and fair lending laws and regulations. The Bank is subject to consumer protection regulations issued by the CFPB, but as a smaller financial institution, is generally subject to supervision and enforcement by the FDIC and DFI with respect to its compliance with federal and state consumer financial protection laws and regulations.

The following is a brief description of certain laws and regulations applicable to Timberland Bancorp and the Bank. Descriptions of laws and regulations here and elsewhere in this report do not purport to be complete and are qualified in their entirety by reference to the actual laws and regulations. Legislation is introduced from time to time in the U.S. Congress or the Washington State Legislature that may affect the operations of Timberland Bancorp and the Bank. In addition, the regulations governing the Company and the Bank may be amended from time to time by the FDIC, DFI, Federal Reserve and the CFPB. Any such legislation or regulatory changes in the future could adversely affect the Company's and the Bank's operations and financial condition. We cannot predict whether any such changes may occur.

Regulation of the Bank

The Bank, as a state-chartered savings bank, is subject to regulation and oversight by the FDIC and the Division extending to all aspects of its operations.

Federal and State Enforcement Authority and Actions. As part of its supervisory authority over Washington-chartered savings banks, the Division may initiate enforcement proceedings to obtain a consent order to cease and desist against an institution believed to have engaged in unsafe and unsound practices or to have violated a law, regulation, or other regulatory limit, including a written agreement. The FDIC also has the authority to initiate enforcement actions against insured institutions for similar reasons and may terminate the deposit insurance if it determines that an institution has engaged in unsafe or unsound practices or is in an unsafe or unsound condition. Both of these agencies may utilize less formal supervisory tools to address their concerns about the condition, operations or compliance status of a savings bank.

Insurance of Accounts and Regulation by the FDIC.  The deposit insurance fund (the "DIF") of the FDIC insures deposit accounts in the Bank up to $250,000 per separately insured deposit ownership right or category.  As insurer, the FDIC imposes deposit insurance premiums and is authorized to conduct examinations of and to require reporting by FDIC-insured institutions. The Bank's deposit insurance premiums for the year ended September 30, 2020 were $204,000.  

Under the FDIC's system for assessing insurance premiums, insured institutions that do not have assets of $10 billion are assessed based on CAMELS component ratings and certain financial ratios. For these institutions, total base assessment rates range from 3 to 30 basis points, subject to adjustment. Stronger institutions pay lower rates, while riskier institutions pay higher rates. Assessments are applied to an institution's assessment base, which is its average consolidated total assets minus average tangible equity. The FDIC has authority to increase insurance assessments, and any significant increases would have an adverse effect on the operating expenses and results of operations of the Bank. Management cannot predict what assessment rates will be in the future.

As insurer, the FDIC is authorized to conduct examinations of and to require reporting by FDIC-insured institutions. It also may prohibit any FDIC-insured institution from engaging in any activity the FDIC determines by regulation or order to pose a serious threat to the DIF. The FDIC also has the authority to take enforcement actions against banks and savings associations. Management is not aware of any existing circumstances which would result in termination of the Bank's deposit insurance.

A significant increase in insurance premiums would likely have an adverse effect on the operating expenses and results of operations of the Bank.  

Capital Requirements.  Federally insured financial institutions, such as the Bank, are required to maintain a minimum level of regulatory capital.

The Bank is subject to capital regulations adopted by the FDIC, which establish minimum required ratios for common equity Tier 1 ("CET1"), leverage and Tier 1 capital ratios, and require an additional capital conservation buffer over the required minimum capital ratios, and defines what qualifies as capital for purposes of meeting the capital requirements. The

Federal Reserve has adopted parallel regulations for bank holding companies. These regulations implement the regulatory capital reforms required by the Dodd Frank Act and the "Basel III" requirements.

Under the capital regulations, the required minimum capital level ratios are (i) a CET1 capital ratio of 4.5%; (ii) a Tier 1 capital ratio of 6.0%; (iii) a total capital ratio of 8.0%; and (iv) a leverage ratio of 4.0%. CET1 generally consists of common stock; retained earnings; accumulated other comprehensive income ("AOCI") unless an institution elects to exclude AOCI from regulatory capital; and certain minority interests; all subject to applicable regulatory adjustments and deductions. Tier 1 capital generally consists of CET1 and noncumulative perpetual preferred stock. Tier 2 capital generally consists of other preferred stock and subordinated debt meeting certain conditions plus an amount of the allowance for loan and lease losses up to 1.25% of assets. Total capital is the sum of Tier 1 and Tier 2 capital. The leverage ratio is the ratio of Tier 1 capital to average consolidated assets as reported on Call Reports, minus certain items deducted from Tier 1 capital. To be considered "well capitalized," a depository institution must have a (i) a total risk-based capital ratio of 10.0% or more, (ii) a CET1 risk-based capital ratio of 6.5% or more, (iii) a Tier 1 risk-based capital ratio of 8.0% or more, and (iv) a leverage ratio of 5.0% or more, and is not subject to any of certain specified requirements to meet and maintain a specific capital level for any capital measure.

In addition to the minimum capital requirements, the Bank must maintain a capital conservation buffer that consists of additional CET1 capital greater than 2.5% of risk-weighted assets above the required minimum risk-based capital ratios in order to avoid limitations on paying dividends, repurchasing shares and paying certain discretionary bonuses. At September 30, 2020, the Bank met the requirements to be "well capitalized" and the Bank's CET1 capital exceeded the required conservation buffer.

The following table compares the Bank's actual capital amounts at September 30, 2020 to its minimum regulatory capital requirements at that date (Dollars in thousands):

	Actual				Regulatory Minimum To Be "Adequately Capitalized				Regulatory Minimum To Be "Well Capitalized" Under Prompt Corrective Action Provisions
	Amount		Ratio		Amount		Ratio		Amount		Ratio
Leverage Capital Ratio:
Tier 1 capital	$	168,937	11.1	%	$	60,993	4.0	%	$	76,241	5.0	%
Risk-based Capital Ratios:
CET1 capital	168,937		19.7		38,504		4.5		55,618		6.5
Tier 1 capital	168,937		19.7		51,339		6.0		68,452		8.0
Total capital	179,671		21.0		68,452		8.0		85,566		10.0

The FDIC also has authority to establish individual minimum capital requirements in appropriate cases upon a determination that an institution's capital level is or may become inadequate in light of particular risks or circumstances. Management of the Bank believes that, under the current regulations, the Bank will continue to meet its minimum capital requirements in the foreseeable future.

For additional information regarding the Bank's regulatory capital requirements, see Note 18 of the Notes to the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data" of this Form 10-K.

In September 2019, the FDIC and other federal banking agencies adopted a final rule, effective January 1, 2020, creating a community bank leverage ratio ("CBLR") for institutions that have total consolidated assets of $10 billion or less and meet other qualifying criteria. The CBLR provides a simple measure of capital adequacy for qualifying institutions. Qualifying institutions that elect to use the CBLR framework and that maintain a leverage capital ratio of greater than 9% will be considered to have satisfied the general applicable risk-based and leverage capital requirements in the regulatory agencies' capital rules and to have met the well-capitalized ratio requirements. The Bank has not elected to use the CBLR framework as of September 30, 2020.

The Financial Accounting Standards Board has adopted a new accounting standard for GAAP that will be effective for us for our first fiscal year beginning after December 15, 2022. This standard, referred to as Current Expected Credit Loss, or CECL, requires FDIC-insured institutions and their holding companies (banking organizations) to recognize credit losses

29

expected over the life of certain financial assets. CECL covers a broader range of assets than the current method of recognizing credit losses and generally results in earlier recognition of credit losses. Upon adoption of CECL, a banking organization must record a one-time adjustment to its credit loss allowances as of the beginning of the fiscal year of adoption equal to the difference, if any, between the amount of credit loss allowances under the current methodology and the amount required under CECL. For a banking organization, implementation of CECL is generally likely to reduce retained earnings, and to affect other items, in a manner that reduces its regulatory capital.

The federal banking regulators (the Federal Reserve, the Office of the Comptroller of the Currency and the FDIC) have adopted a rule that gives a banking organization the option to phase in over a three-year period the day-one adverse effects of CECL on its regulatory capital.

Prompt Corrective Action.  Federal statutes establish a supervisory framework based on five capital categories:  well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized.  An institution’s category depends upon where its capital levels are in relation to relevant capital measures, which include a risk-based capital measure, a leverage ratio capital measure and certain other factors.  An institution that is not well capitalized is subject to certain restrictions on brokered deposits, including restrictions on the rates it can offer on its deposits generally. Any institution which is neither well capitalized nor adequately capitalized is considered undercapitalized.

Undercapitalized institutions are subject to certain prompt corrective action requirements, regulatory controls and restrictions which become more extensive as an institution becomes more severely undercapitalized.  Failure by an institution to comply with applicable capital requirements would, if unremedied, result in progressively more severe restrictions on its activities and lead to enforcement actions, including, but not limited to, the issuance of a capital directive to ensure the maintenance of required capital levels and, ultimately, the appointment of the FDIC as receiver or conservator.  Banking regulators will take prompt corrective action with respect to depository institutions that do not meet minimum capital requirements.  Additionally, approval of any regulatory application filed for their review may be dependent on compliance with capital requirements.

At September 30, 2020, the Bank was categorized as “well capitalized” under the prompt corrective action regulations of the FDIC.  For additional information regarding the Bank's minimum regulatory capital requirements, see "Capital Requirements" above and Note 18 of the Notes to the Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” of this Form 10-K.

Federal Home Loan Bank System. The Bank is a member of the FHLB, one of 11 regional Federal Home Loan Banks that administer the home financing credit function of savings institutions, each serving as a reserve or central bank for its members within its assigned region.  The FHLB is funded primarily from proceeds derived from the sale of consolidated obligations of the FHLB System.  It makes loans to members in accordance with policies and procedures, established by the Board of Directors of the FHLB, which are subject to the oversight of the Federal Housing Finance Board.  All borrowings from the FHLB are required to be fully secured by sufficient collateral as determined by the FHLB.  In addition, all long-term borrowings are required to provide funds for residential home financing.  See “Deposit Activities and Other Sources of Funds – Borrowings" above.

As a member, the Bank is required to purchase and maintain stock in the FHLB based on the Bank's asset size and level of borrowings from the FHLB.  At September 30, 2020, the Bank had $1.92 million in FHLB stock, which was in compliance with this requirement.  The FHLB pays dividends quarterly, and the Bank received $52,000 in dividends during the year ended September 30, 2020.

The Federal Home Loan Banks continue to contribute to low- and moderately-priced housing programs through direct loans or interest subsidies on borrowings targeted for community investment and low- and moderate-income housing projects.  These contributions have adversely affected the level of FHLB dividends paid and could continue to do so in the future.  These contributions could also have an adverse effect on the value of FHLB stock in the future.  A reduction in value of the Bank's FHLB stock may result in a decrease in net income and possibly capital.

Standards for Safety and Soundness.  The federal banking regulatory agencies have prescribed, by regulation, guidelines for all insured depository institutions relating to: internal controls, information systems and internal audit systems, loan documentation, credit underwriting, interest rate risk exposure, asset growth, asset quality, earnings, compensation, fees and benefits.  The guidelines set forth the safety and soundness standards that the federal banking agencies use to identify and address problems at insured depository institutions before capital becomes impaired.  Each insured depository institution must implement a comprehensive written information security program that includes administrative, technical and physical safeguards appropriate to the institution’s size and complexity and the nature and scope of its activities.  The information security program also must be designed to ensure the security and confidentiality of customer information, protect against any

30

unanticipated threats or hazards to the security or integrity of such information, protect against unauthorized access to or use of such information that could result in substantial harm or inconvenience to any customer, and ensure the proper disposal of customer and consumer information.  Each insured depository institution must also develop and implement a risk-based response program to address incidents of unauthorized access to customer information in customer information systems.  If the FDIC determines that the Bank fails to meet any standard prescribed by the guidelines, it may require the Bank to submit to the agency an acceptable plan to achieve compliance with the standard.  FDIC regulations establish deadlines for the submission and review of such safety and soundness compliance plans.  Management of the Bank is not aware of any conditions relating to these safety and soundness standards which would require submission of a plan of compliance.

Real Estate Lending Standards.  FDIC regulations require the Bank to adopt and maintain written policies that establish appropriate limits and standards for real estate loans.  These standards, which must be consistent with safe and sound banking practices, must establish loan portfolio diversification standards, prudent underwriting standards (including loan-to-value ratio limits) that are clear and measurable, loan administration procedures, and documentation, approval and reporting requirements.  The Bank is obligated to monitor conditions in its real estate markets to ensure that its standards continue to be appropriate for current market conditions.  The Bank’s Board of Directors is required to review and approve the Bank’s standards at least annually.  The FDIC has published guidelines for compliance with these regulations, including supervisory limitations on loan-to-value ratios for different categories of real estate loans.  Under the guidelines, the aggregate amount of all loans in excess of the supervisory loan-to-value ratios should not exceed 100% of total capital, and the total of all loans for commercial, agricultural, multi-family or other non-one- to four-family residential properties in excess of the supervisory loan-to-value ratio should not exceed 30% of total capital.  Loans in excess of the supervisory loan-to-value ratio limitations must be identified in the Bank’s records and reported at least quarterly to the Bank’s Board of Directors.  The Bank is in compliance with the record and reporting requirements.  As of September 30, 2020, the Bank’s aggregate loans in excess of the supervisory loan-to-value ratios were 0.3% of total capital and the Bank's loans on commercial, agricultural, multi-family or other non-one- to four-family residential properties in excess of the supervisory loan-to-value ratios were 0.1% of total capital.

Activities and Investments of Insured State-Chartered Financial Institutions.  Federal law generally limits the activities and equity investments of FDIC-insured state-chartered banks to those that are permissible for national banks.  An insured state bank is not prohibited from, among other things, (i) acquiring or retaining a majority interest in a subsidiary, (ii) investing as a limited partner in a partnership, the sole purpose of which is direct or indirect investment in the acquisition, rehabilitation or new construction of a qualified housing project, provided that such limited partnership investments may not exceed 2% of the bank's total assets, (iii) acquiring up to 10% of the voting stock of a company that solely provides or reinsures directors' and officers' liability insurance coverage or bankers' blanket bond group insurance coverage for insured depository institutions, and (iv) acquiring or retaining the voting shares of a depository institution owned by another FDIC-insured institution if certain requirements are met.

Under the law of Washington State, Washington-chartered savings banks may exercise any of the powers of Washington-chartered commercial banks, national banks and federally-chartered savings banks, subject to the approval of the Director in certain situations.  In addition,Washington-chartered savings banks may charge the maximum interest rate allowable for loans and other extensions of credit by federally-chartered financial institutions to Washington residents.

Environmental Issues Associated With Real Estate Lending.  The Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) is a federal statute that generally imposes strict liability on all prior and present "owners and operators" of sites containing hazardous waste.  However,  Congress acted to protect secured creditors by providing that the term “owner and operator” excludes a person whose ownership is limited to protecting its security interest in the site.  Since the enactment of the CERCLA, this “secured creditor exemption” has been the subject of judicial interpretations which have left open the possibility that lenders could be liable for cleanup costs on contaminated property that they hold as collateral for a loan.

To the extent that legal uncertainty exists in this area, all creditors, including the Bank, that have made loans secured by properties with potential hazardous waste contamination (such as petroleum contamination) could be subject to liability for cleanup costs, which costs often substantially exceed the value of the collateral property.

Federal Reserve System.  The Federal Reserve requires that all depository institutions maintain reserves on transaction accounts or non-personal time deposits.  These reserves may be in the form of cash or non-interest-bearing deposits with the regional Federal Reserve Bank.  Negotiable order of withdrawal ("NOW") accounts and other types of accounts that permit payments or transfers to third parties fall within the definition of transaction accounts and are subject to reserve requirements, as are any non-personal time deposits at a savings bank.  In response to the COVID-19 pandemic, the Federal Reserve reduced the reserve requirement ratios to zero percent effective on March 26, 2020, to support lending to households and businesses. At September 30, 2020, the Bank was in compliance with the reserve requirements in place at that time.

31

Affiliate Transactions.  Federal laws strictly limit the ability of banks to engage in certain transactions with their affiliates, including their bank holding companies.  Transactions deemed to be a “covered transaction” under Section 23A of the Federal Reserve Act and between a subsidiary bank and its parent company or the nonbank subsidiaries of the bank holding company are limited to 10% of the bank subsidiary’s capital and surplus and, with respect to the parent company and all such nonbank subsidiaries, to an aggregate of 20% of the bank subsidiary’s capital and surplus.  Further, covered transactions that are loans and extensions of credit generally are required to be secured by eligible collateral in specified amounts.  Federal law also requires that covered transactions and certain other transactions between a bank and its affiliates listed in Section 23B of the Federal Reserve Act and related regulations must be on terms as favorable to the bank as transactions with non-affiliates.

Community Reinvestment Act. Banks are also subject to the provisions of the Community Reinvestment Act of 1977 (“CRA”), which requires the appropriate federal bank regulatory agency to assess a bank’s performance under the CRA in meeting the credit needs of the community serviced by the bank, including low- and moderate-income neighborhoods.  The regulatory agency’s assessment of the bank’s record is made available to the public.  Further, a bank’s performance must be considered in connection with a bank’s application to, among other things, establish a new branch office that will accept deposits, relocate an existing office or merge or consolidate with, or acquire the assets or assume the liabilities of, a federally regulated financial institution.  The Bank received a “satisfactory” rating during its most recent examination.

Dividends.  Dividends from the Bank constitute the major source of funds available for dividends which may be paid to Company shareholders.  The amount of dividends payable by the Bank to the Company depends upon the Bank's earnings and capital position, and is limited by federal and state laws, regulations and policies. According to Washington law, the Bank may not declare or pay a cash dividend on its capital stock if it would cause its net worth to be reduced below (i) the amount required for liquidation accounts or (ii) the net worth requirements, if any, imposed by the Director of the Division. In addition, dividends on the Bank's capital stock may not be paid in an aggregate amount greater than the aggregate retained earnings of the Bank, without the approval of the Director of the Division. Dividends payable by the Bank can be limited or prohibited if the Bank does not meet the capital conservation buffer requirement.

The amount of dividends actually paid during any one period will be strongly affected by the Bank's management policy of maintaining a strong capital position.  Federal law further provides that no insured depository institution may pay a cash dividend if it would cause the institution to be “undercapitalized,” as defined in the prompt corrective action regulations.  Moreover, the federal bank regulatory agencies also have the general authority to limit the dividends paid by insured banks if such payments should be deemed to constitute an unsafe and unsound practice.

Other Consumer Protection Laws and Regulations.  The Bank is subject to a broad array of federal and state consumer protection laws and regulations that govern almost every aspect of its business relationships with consumers.  While the list set forth below is not exhaustive, these include the Truth-in-Lending Act, the Truth in Savings Act, the Electronic Fund Transfer Act, the Expedited Funds Availability Act, the Equal Credit Opportunity Act, the Fair Housing Act, the Real Estate Settlement Procedures Act, the Home Mortgage Disclosure Act, the Fair Credit Reporting Act, the Fair Debt Collection Practices Act, the Right to Financial Privacy Act, the Home Ownership and Equity Protection Act, the Consumer Leasing Act, the Fair Credit Billing Act, the Homeowners Protection Act, the Check Clearing for the 21st Century Act, laws governing flood insurance, laws governing consumer protections in connection with the sale of insurance, federal and state laws prohibiting unfair and deceptive business practices, and various regulations that implement some or all of the foregoing.  These laws and regulations mandate certain disclosure requirements and regulate the manner in which financial institutions must deal with customers when taking deposits, making loans, collecting loans, and providing other services.  Failure to comply with these laws and regulations can subject the Bank to various penalties, including but not limited to, enforcement actions, injunctions, fines, civil liability, criminal penalties, punitive damages, and the loss of certain contractual rights.

Regulation of the Company

General.  The Company, as the sole shareholder of the Bank, is a bank holding company registered with the Federal Reserve.  Bank holding companies are subject to comprehensive regulation by the Federal Reserve under the Bank Holding Company Act of 1956, as amended (“BHCA”), and the regulations promulgated thereunder.  This regulation and oversight is generally intended to ensure that the Company limits its activities to those allowed by law and that it operates in a safe and sound manner without endangering the financial health of the Bank.

As a bank holding company, the Company is required to file quarterly reports with the Federal Reserve and any additional information required by the Federal Reserve and is subject to regular examinations by the Federal Reserve.  The Federal Reserve also has extensive enforcement authority over bank holding companies, including the ability to assess civil money penalties, to issue cease and desist or removal orders and to require that a holding company divest subsidiaries (including its bank subsidiaries).  In general, enforcement actions may be initiated for violations of laws and regulations and unsafe or unsound practices.

32

BHCA.  The Company is supervised by the Federal Reserve under the BHCA.  Federal Reserve policy requires that a bank holding company serve as a source of financial and managerial strength to its subsidiary banks and may not conduct its operations in an unsafe or unsound manner.  In addition, the Federal Reserve provides that bank holding companies should serve as a source of strength to its subsidiary banks by being prepared to use available resources to provide adequate capital funds to its subsidiary banks during periods of financial stress or adversity, and should maintain the financial flexibility and capital raising capacity to obtain additional resources for assisting its subsidiary banks.  A bank holding company's failure to meet its obligation to serve as a source of strength to its subsidiary bank will generally be considered by the Federal Reserve to be an unsafe and unsound banking practice or a violation of the Federal Reserve's regulations or both. The Dodd-Frank Act essentially codified this policy.

Under the BHCA, the Federal Reserve may approve the ownership of shares by a bank holding company in any company the activities of which the Federal Reserve has determined to be so closely related to the business of banking or managing or controlling banks as to be a proper incident thereto.  These activities generally include, among others, operating a savings institution, mortgage company, finance company, escrow company, credit card company or factoring company; performing certain data processing operations; providing certain investment and financial advice; underwriting and acting as an insurance agent for certain types of credit related insurance; leasing property on a full payout, non-operating basis; selling money orders, travelers’ checks and U.S. Savings Bonds; real estate and personal property appraising; providing tax planning and preparation services; and, subject to certain limitations, providing securities brokerage services for customers.

Acquisitions.  The BHCA prohibits a bank holding company, with certain exceptions, from acquiring direct or indirect ownership or control of more than 5% of the voting shares of any company that is not a bank or bank holding company and from engaging directly or indirectly in activities other than those of banking, managing or controlling banks, or providing services for its subsidiaries.  Under the BHCA, the Federal Reserve may approve the ownership of shares by a bank holding company in any company, the activities of which the Federal Reserve has determined to be so closely related to the business of banking or managing or controlling banks as to be a proper incident thereto. A bank holding company that meets certain supervisory and financial standards and elects to be designated as a financial holding company may also engage in certain securities, insurance and merchant banking activities and other activities determined to be financial in nature or incidental to financial activities. The Federal Reserve much approve the acquisition (or acquisition of control) of a bank or other FDIC-insured depository institution by a bank holding company, and the appropriate federal banking regulator must approve a bank's acquisition (or acquisition of control) of another bank or other FDIC-insured institution.  

Interstate Banking.  The Federal Reserve may approve an application of a bank holding company to acquire control of, or acquire all or substantially all of the assets of, a bank located in a state other than such holding company's home state, without regard to whether the transaction is prohibited by the laws of any state except with respect to the acquisition of a bank that has not been in existence for the minimum time period, not exceeding five years, specified by the law of the host state.  The Federal Reserve may not approve an application if the applicant controls or would control more than 10% of the insured deposits in the U.S. or 30% or more of the deposits in the target bank's home state or in any state in which the target bank maintains a branch.  Federal law does not affect the authority of states to limit the percentage of total insured deposits in the state that may be held or controlled by a bank holding company to the extent such limitation does not discriminate against out-of-state banks or bank holding companies.  Individual states may also waive the 30% state-wide concentration limit contained in the federal law.

The federal banking agencies are authorized to approve interstate merger transactions without regard to whether such transaction is prohibited by the law of any state, unless the home state of one of the banks adopted a law prior to June 1, 1997 which applies equally to all out-of-state banks and expressly prohibits merger transactions involving out-of-state banks. Interstate acquisitions of branches will be permitted only if the law of the state in which the branch is located permits such acquisitions.  Interstate mergers and branch acquisitions are also generally subject to the nationwide and statewide insured deposit concentration amounts described above.

Dividends.  Federal Reserve policy limits the payment of cash dividends by bank holding companies, which expresses the Federal Reserve's view that a bank holding company should pay cash dividends only to the extent that the company's net income for the past year is sufficient to cover both the cash dividends and a rate of earning retention that is consistent with the company's capital needs, asset quality and overall financial condition, and that it is inappropriate for a company experiencing serious financial problems to borrow funds to pay dividends.  Under Washington corporate law, the Company generally may not pay dividends if after that payment it would not be able to pay its liabilities as they become due in the usual course of business, or its total assets would be less than its total liabilities. The capital conservation buffer requirement can also limit dividends.

33

Stock Repurchases.  Bank holding companies, except for certain “well-capitalized” and highly rated bank holding companies, are required to give the Federal Reserve prior written notice of any purchase or redemption of its outstanding equity securities if the consideration for the purchase or redemption, when combined with the net consideration paid for all such purchases or redemptions during the preceding 12 months, is equal to 10% or more of their consolidated net worth.  The Federal Reserve may disapprove a purchase or redemption if it determines that the proposal would constitute an unsafe or unsound practice or would violate any law, regulation, Federal Reserve order, or any condition imposed by, or written agreement with, the Federal Reserve.  

Capital Requirements.  As a bank holding company registered with the Federal Reserve, the Company is subject to the capital adequacy requirements of the Federal Reserve under the BHCA and the regulations of the Federal Reserve. For a bank holding company with less than $3.00 billion in assets, the capital guidelines apply on a bank only basis, and the Federal Reserve expects the holding company's subsidiary bank to be well capitalized under the prompt corrective action regulations. If the Company were subject to regulatory guidelines for bank holding companies with $3.00 billion or more in assets, at September 30, 2020, the Company would have exceeded all regulatory requirements.

The following table presents the regulatory capital ratios for the Company as of September 30, 2020 (Dollars in thousands):

	Actual
	Amount		Ratio
Leverage Capital Ratio:
Tier 1 capital	$	172,000	11.3	%
Risk-based Capital Ratios:
CET1 capital	172,000		20.1
Tier 1 capital	172,000		20.1
Total capital	182,805		21.3

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Among other requirements, the Dodd-Frank Act requires public companies, such as Timberland Bancorp, to (i) provide their shareholders with a non-binding vote (a) at least once every three years on the compensation paid to executive officers and (b) at least once every six years on whether they should have a “say on pay” vote every one, two or three years; (ii) have a separate, non-binding shareholder vote regarding golden parachutes for named executive officers when a shareholder vote takes place on mergers, acquisitions, dispositions or other transactions that would trigger the parachute payments; (iii) provide disclosure in annual proxy materials concerning the relationship between the executive compensation paid and the financial performance of the issuer; and (iv) amend Item 402 of Regulation S-K to require companies to disclose the ratio of the Chief Executive Officer's annual total compensation to the median annual total compensation of all other employees. For certain of these changes, the implementing regulations have not been promulgated, so the full impact of the Dodd-Frank Act on public companies cannot be determined at this time.

2018 Regulatory Reform. In May 2018 the Economic Growth, Regulatory Relief and Consumer Protection Act (the “2018 Act”), was enacted to modify or remove certain financial reform rules and regulations, including some of those implemented under the Dodd-Frank Act. While the 2018 Act maintains most of the regulatory structure established by the Dodd-Frank Act, it amends certain aspects of the regulatory framework for small depository institutions with assets of less than $10 billion and for large banks with assets of more than $50 billion. Many of these changes could result in meaningful regulatory changes for community banks such as the Bank, and their holding companies.

The 2018 Act, among other matters, expands the definition of qualified mortgages which may be held by a financial institution and simplifies the regulatory capital rules for financial institutions and their holding companies with total consolidated assets of less than $10 billion by instructing the federal banking regulators to establish a single CBLR of between 8 and 10 percent, as described above. Any qualifying depository institution or its holding company that exceeds the CBLR will be considered to have met generally applicable leverage and risk-based regulatory capital requirements and any qualifying depository institution that exceeds the new ratio will be considered to be “well capitalized” under the prompt corrective action rules.

34

The 2018 Act also expands the category of holding companies that may rely on the “Small Bank Holding Company and Savings and Loan Holding Company Policy Statement” by raising the maximum amount of assets a qualifying holding company may have from $1 billion to $3 billion. A major effect of this change is to exclude such holding companies from the minimum capital requirements of the Dodd-Frank Act. In addition, the 2018 Act includes regulatory relief for community banks regarding regulatory examination cycles, call reports, the Volcker Rule (proprietary trading prohibitions), mortgage disclosures and risk weights for certain high-risk commercial real estate loans.

It is difficult at this time to predict when or how any new standards under the 2018 Act will ultimately be applied to us or what specific impact the 2018 Act and the yet-to-be-written implementing rules and regulations will have on community banks.

Taxation

Federal Taxation

General.  The Company and the Bank report their operations on a fiscal year basis using the accrual method of accounting and are subject to federal income taxation in the same manner as other corporations.  The following discussion of tax matters is intended only as a summary and does not purport to be a comprehensive description of the tax rules applicable to the Bank or the Company.

On December 22, 2017, the U.S. Government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act amends the Internal Revenue Code to reduce tax rates and modify policies, credits, and deductions for individuals and businesses. For businesses, the Tax Act reduced the corporate federal income tax rate from a maximum of 35.0% to a flat 21.0%. The corporate federal income tax rate reduction was effective January 1, 2018. Since the Company has a fiscal year end of September 30, the reduced federal corporate income tax rate for fiscal year 2018 was the result of the application of a blended federal statutory tax rate of 24.5%, which was based on the applicable tax rates before and after the Tax Act and corresponding number of days in the fiscal year before and after enactment, and then a 21.0% federal corporate income tax rate for fiscal 2019 and thereafter. The Tax Act also required a revaluation of the Company’s deferred tax assets and liabilities to account for the future impact of lower corporate income tax rates and other provisions of the legislation. As a result of the Company’s revaluation, the net deferred tax asset (“DTA”) was reduced through an increase to the provision for income taxes. The revaluation of the DTA balance resulted in a one-time increase for the fiscal year ended September 30, 2018 to federal income tax of $548,000. For additional details see Note 14 of the Notes to Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

Dividends-Received Deduction. The Company may exclude from its income 100.0% of dividends received from the Bank as a member of the same affiliated group of corporations.  The corporate dividends-received deduction is generally 70.0% in the case of dividends received from unaffiliated corporations with which the Company and the Bank will not file a consolidated tax return, except that if the Company or the Bank owns more than 20.0% of the stock of a corporation distributing a dividend, then 80.0% of any dividends received may be deducted.

Audits.  The Company is no longer subject to U.S. federal tax examination by tax authorities for years ended on or before September 30, 2016.

Washington Taxation

The Company and the Bank are subject to a business and occupation tax imposed under Washington law at the rate of 1.8% of gross receipts at September 30, 2020. Interest received on loans secured by mortgages or deeds of trust on residential properties, certain residential mortgage-backed securities, and certain U.S. government and agency securities is not subject to this tax.

Competition

The Bank operates in an intensely competitive market for the attraction of deposits (generally its primary source of lendable funds) and in the origination of loans.  Historically, its most direct competition for deposits has come from commercial banks, thrift institutions and credit unions in its primary market area.  In times of high interest rates, the Bank experiences additional significant competition for investors' funds from short-term money market securities and other corporate and government securities.  The Bank's competition for loans comes principally from mortgage bankers, commercial banks, thrift

35

institutions and credit unions.  Such competition for deposits and the origination of loans may limit the Bank's future growth and earnings prospects.

Subsidiary Activities

The Bank has one wholly-owned subsidiary, Timberland Service Corporation (“Timberland Service”), whose primary function is to provide escrow services.

Employees and Human Capital Resources

As of September 30, 2020, the Company had 267 full-time employees and 19 part-time and on-call employees.  The employees are not represented by a collective bargaining unit, and the Company believes its relationship with its employees is good. We believe our ability to attract and retain employees is a key to our success. Accordingly, we strive to offer competitive salaries and employee benefits to all employees and monitor salaries in our market areas.

Item 1A.  Risk Factors

We assume and manage a certain degree of risk in order to conduct our business strategy.  In addition to the risk factors described below, other risks and uncertainties not specifically mentioned, or that are currently known to, or deemed to be immaterial by management, also may materially and adversely affect our financial position, results of operations and/or cash flows.  Before making an investment decision, you should carefully consider the risks described below together with all of the other information included in this Form 10-K and our other filings with the SEC.  If any of the circumstances described in the following risk factors actually occur to a significant degree, the value of our common stock could decline, and you could lose all or part of your investment. This report is qualified in its entirety by these risk factors.

Risks Related to the COVID-19 Pandemic and Associated Economic Slowdown

The COVID-19 pandemic has adversely impacted our ability to conduct business and is expected to adversely impact our financial results and those of our customers. The ultimate impact will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities in response to the pandemic.

The COVID-19 pandemic has significantly adversely affected our operations and the way we provide banking services to businesses and individuals, many of whom are currently under some level of government restrictions.  As an essential business, we continue to provide banking and financial services to our customers with drive-thru access available at the majority of our branch locations and in-person services available by appointment. We have also opened several branch lobbies with modified access. In addition, we continue to provide access to banking and financial services through online banking, ATMs and by telephone. If the COVID-19 pandemic worsens it could limit or disrupt our ability to provide banking and financial services to our customers.

A number of our employees currently are working remotely to enable us to continue to provide banking services to our customers. Heightened cybersecurity, information security and operational risks may result from these remote work-from-home arrangements. We also could be adversely affected if key personnel or a significant number of employees were to become unavailable due to the effects and restrictions of the COVID-19 pandemic. We also rely upon our third-party vendors to conduct business and to process, record and monitor transactions. If any of these vendors are unable to continue to provide us with these services, it could negatively impact our ability to serve our customers. Although we have business continuity plans and other safeguards in place, there is no assurance that such plans and safeguards will be effective.

There is pervasive uncertainty surrounding the future economic conditions that will emerge in the months and years following the start of the pandemic. As a result, management is confronted with a significant and unfamiliar degree of uncertainty in estimating the impact of the pandemic on credit quality, revenues and asset values. To date, the COVID-19 pandemic has resulted in changes in the demand for certain loan types, including government sponsored programs such as the Paycheck Protection Program ("PPP") through August 2020, deposit availability, market interest rates and negatively impacted many of our business and consumer borrower’s ability to make their loan payments. Because the length of the pandemic and the efficacy of the extraordinary measures being put in place to address its economic consequences are unknown, including a continued low targeted federal funds rate, until the pandemic subsides, we expect our net interest income and net interest margin will be adversely affected. Many of our borrowers have become unemployed or may face unemployment, and certain businesses are at risk of insolvency as their revenues decline precipitously, especially in businesses related to travel, hospitality, leisure and physical personal services. Businesses may ultimately not reopen as there is a significant level of uncertainty

37

regarding the level of economic activity that will return to our markets over time, the impact of governmental assistance, the speed of economic recovery, the resurgence of COVID-19 in subsequent seasons and changes to demographic and social norms that will take place.

The impact of the pandemic is expected to continue to adversely affect us during the 2021 fiscal year and possibly longer as the ability of many of our customers to make loan payments has been significantly affected. Although the Company makes estimates of loan losses related to the pandemic as part of its evaluation of the allowance for loan losses, such estimates involve significant judgment and are made in the context of significant uncertainty as to the impact the pandemic will have on the credit quality of our loan portfolio. Consistent with guidance provided by banking regulators, we have modified loans by providing various loan payment deferral options to our borrowers affected by the COVID-19 pandemic. Notwithstanding these modifications, not all of these borrowers may be able to resume making full payments on their loans once the COVID-19 pandemic is resolved. Any increases in the allowance for credit losses will result in a decrease in net income and, most likely, capital, and may have a material negative effect on our financial condition and results of operations.

As of September 30, 2020, we hold and service SBA PPP loans with an aggregate balance of $126.82 million. These SBA PPP loans are subject to the provisions of the CARES Act and to complex and evolving rules and guidance issued by the SBA and other government agencies. We expect that the great majority of our SBA PPP borrowers will seek full or partial forgiveness of their loan obligations. We have credit risk on SBA PPP loans if the SBA determines that there is a deficiency in the manner in which we originated, funded or serviced loans, including any issue with the eligibility of a borrower to receive a SBA PPP loan. We could face additional risks in our administrative capabilities to service our SBA PPP loans, and risk with respect to the determination of loan forgiveness, depending on the final procedures for determining loan forgiveness. In the event of a loss resulting from a default on a SBA PPP loan and a determination by the SBA that there was a deficiency in the manner in which we originated, funded or serviced a SBA PPP loan, the SBA may deny its liability under the guaranty, reduce the amount of the guaranty or, if the SBA has already paid under the guaranty, seek recovery of any loss related to the deficiency from us.

In accordance with GAAP, we record assets acquired and liabilities assumed at their fair value with the excess of the purchase consideration over the net assets acquired resulting in the recognition of goodwill. If adverse economic conditions or the recent decrease in our stock price and market capitalization as a result of the pandemic were to be deemed sustained rather than temporary, it may significantly affect the fair value of our goodwill and may trigger impairment charges. Any impairment charge could have a material adverse effect on our results of operations and financial condition.

We are an entity separate and distinct from our principal subsidiary, Timberland Bank, and derive substantially all of our revenue at the holding company level in the form of dividends from that subsidiary. If the COVID-19 pandemic were to materially adversely affect Timberland Bank’s regulatory capital levels or liquidity, it may result in Timberland Bank being unable to pay dividends to us, which may result in our not being able to pay dividends on our common stock at the same rate or at all.

Even after the COVID-19 pandemic subsides, the U.S. economy will likely require some time to recover from its effects, the length of which is unknown. and during which we may experience a recession. As a result, we anticipate our business may be materially and adversely affected during this recovery. To the extent the effects of the COVID-19 pandemic adversely impact our business, financial condition, liquidity or results of operations, it may also have the effect of heightening many of the other risks described in this section.

Risks Related to Economic Conditions

Our business may be adversely affected by downturns in the national economy and in the economies in our market areas.

Substantially all of our loans are to businesses and individuals in the state of Washington. A decline in the economies of our local market areas of Grays Harbor, Pierce, Thurston, King, Kitsap and Lewis counties in which we operate, and which we consider to be our primary market areas, could have a material adverse effect on our business, financial condition, results of operations and prospects. Weakness in the global economy has adversely affected many businesses operating in our markets that are dependent upon international trade and it is not known how the recent changes in tariffs being imposed on international trade may also affect these businesses.

While real estate values and unemployment rates have recently improved, a deterioration in economic conditions in the market areas we serve could result in the following consequences, any of which could have a materially adverse impact on our business, financial condition and results of operations:

•loan delinquencies, problem assets and foreclosures may increase;

•we may increase our allowance for loan losses;

38

•the sale of foreclosed assets may slow;

•demand for our products and services may decline possibly resulting in a decrease in our total loans or assets;

•collateral for loans made may decline in value, exposing us to increased risk loans, reducing customers’ borrowing power, and reducing the value of assets and collateral associated with existing loans;

•the net worth and liquidity of loan guarantors may decline, impairing their ability to honor commitments to us; and

•the amount of our low-cost or non-interest bearing deposits may decrease and the composition of our deposits may be adversely affected.

A decline in local economic conditions may have a greater effect on our earnings and capital than on the earnings and capital of larger financial institutions whose real estate loans are geographically diverse. Many of the loans in our portfolio are secured by real estate. Deterioration in the real estate markets where collateral for a mortgage loan is located could negatively affect the borrower's ability to repay the loan and the value of the collateral securing the loan. Real estate values are affected by various other factors, including changes in general or regional economic conditions, government rules or policies and natural disasters such as fires and earthquakes. If we are required to liquidate a significant amount of collateral during a period of reduced real estate values, our financial condition and profitability could be adversely affected.    

Risks Related to our Lending Activities

Our real estate construction and land loans expose us to significant risks.

We make real estate construction loans to individuals and builders, primarily for the construction of residential properties. We originate these loans whether or not the collateral property underlying the loan is under contract for sale. At September 30, 2020, construction loans totaled $219.50 million, or 19.4% of our total loan portfolio, of which $178.64 million were for residential real estate projects, $33.14 million for commercial real estate projects and $7.71 million for land development projects. This compares to total construction loans of $223.53 million, or 22.5% of our total loan portfolio at September 30, 2019, or a decrease of 1.8% during the past year. Approximately $129.57 million of our residential construction loans at September 30, 2020 were made to finance the construction of owner-occupied homes and are structured to be converted to permanent loans at the end of the construction phase.  In general, construction lending involves additional risks because funds are advanced upon estimates of costs in relation to values associated with the completed project. Construction lending involves additional risks when compared with permanent residential lending because funds are advanced upon the collateral for the project based on an estimate of costs that will produce a future value at completion. Because of the uncertainties inherent in estimating construction costs, as well as the market value of the complete project and the effects of governmental regulation on real property, it is relatively difficult to evaluate accurately the total funds required to complete a project and the completed project loan-to-value ratio. Changes in demand for new housing and higher than anticipated building costs may cause actual results to vary significantly from those estimated. For these reasons, this type of lending also typically involves higher loan principal amounts and may be concentrated with a small number of builders. A downturn in housing, or the real estate market, could increase delinquencies, defaults and foreclosures, and significantly impair the value of our collateral and our ability to sell the collateral upon foreclosure. Some of the builders we deal with have more than one loan outstanding with us. Consequently, an adverse development with respect to one loan or one credit relationship can expose us to a significantly greater risk of loss. In addition during the term of some of our construction loans, no payment from the borrower is required since the accumulated interest is added to the principal of the loan through an interest reserve. As a result, these loans often involve the disbursement of funds with repayment substantially dependent on the success of the ultimate project and the ability of the borrower to sell or lease the property or obtain permanent take-out financing, rather than the ability of the borrower or guarantor to repay principal and interest. If our appraisal of the value of a completed project proves to be overstated, we may have inadequate security for the repayment of the loan upon completion of construction of the project and may incur a loss. Because construction loans require active monitoring of the building process, including cost comparisons and on-site inspections, these loans are more difficult and costly to monitor. Increases in market rates of interest may have a more pronounced effect on construction loans by rapidly increasing the end-purchaser's borrowing costs, thereby possibly reducing the homeowner's ability to finance the home upon completion or the overall demand for the project. Properties under construction are often difficult to sell and typically must be completed in order to be successfully sold which also complicates the process of working our problem construction loans. This may require us to advance additional funds and/or contract with another builder to complete construction and assume the market risk of selling the project at a future market price, which may or may not enable us to fully recover unpaid loan funds and associated construction and liquidation costs. Furthermore, in the case of speculative construction loans, there is the added risk associated with identifying an end-purchaser for the finished project. At September 30, 2020, $14.59 million of our construction portfolio was comprised of speculative one- to four-family construction loans. We also make land loans for the acquisition of land upon which the purchaser can then build or make improvements necessary to build or to use for recreational purposes. At September 30, 2020, land loans totaled $25.71 million, or 2.3% of our total loan portfolio. Loans on land under development or held for future construction as well as land loans made to individuals for the future construction of a residence also pose additional risk because the length of time from financing to completion of a

39

development project is significantly longer than for a traditional construction loan, which makes them more susceptible to declines in real estate values, declines in overall economic conditions which may delay the development of the land and changes in the political landscape that could affect the permitted and intended use of the land being financed, and the potential illiquid nature of the collateral. In addition, during this long period of time from financing to completion, the collateral often does not generate any cash flow to support the debt service. At September 30, 2020, all construction loans were performing in accordance to their terms and $394,000 of land loans were non-performing.  A material increase in our non-performing construction or land loans could have a material adverse effect on our financial condition and results of operation.

Our emphasis on commercial real estate lending may expose us to increased lending risks.

Our current business strategy includes an emphasis on commercial real estate lending. This type of lending activity, while potentially more profitable than single-family residential lending, is generally more sensitive to regional and local economic conditions, making loss levels more difficult to predict. Collateral evaluation and financial statement analysis in these types of loans requires a more detailed analysis at the time of loan underwriting and on an ongoing basis. In our primary market of western Washington, a downturn in the real estate market could increase loan delinquencies, defaults and foreclosures, and significantly impair the value of our collateral and our ability to sell the collateral upon foreclosure. Many of our commercial borrowers have more than one loan outstanding with us. Consequently, an adverse development with respect to one loan or one credit relationship can expose us to a significantly greater risk of loss.

At September 30, 2020, we had $453.57 million of commercial real estate mortgage loans, representing 40.0% of our total loan portfolio.  These loans typically involve higher principal amounts than other types of loans, and repayment is dependent upon income generated, or expected to be generated, by the property securing the loan in amounts sufficient to cover operating expenses and debt service, which may be adversely affected by changes in the economy or local market conditions. For example, if the cash flow from the borrower’s project is reduced as a result of leases not being obtained or renewed, the borrower’s ability to repay the loan may be impaired. Commercial real estate loans also expose a lender to greater credit risk than loans secured by residential real estate because the collateral securing these loans typically cannot be sold as easily as residential real estate. In addition, many of our commercial real estate loans are not fully amortizing and contain large balloon payments upon maturity. Such balloon payments may require the borrower to either sell or refinance the underlying property in order to make the payment, which may increase the risk of default or non-payment.

A secondary market for most types of commercial real estate loans is not readily liquid, so we have less opportunity to mitigate credit risk by selling part or all of our interest in these loans.  As a result of these characteristics, if we foreclose on a commercial real estate loan, our holding period for the collateral typically is longer than for one- to four-family residential mortgage loans because there are fewer potential purchasers of the collateral. Accordingly, charge-offs on commercial real estate loans may be larger as a percentage of the total principal outstanding than those incurred with our residential or consumer loan portfolios.

The level of our commercial real estate loan portfolio may subject us to additional regulatory scrutiny.

The FDIC, the Federal Reserve and the Office of the Comptroller of the Currency have promulgated joint guidance on sound risk management practices for financial institutions with concentrations in commercial real estate lending. Under this guidance, a financial institution that, like us, is actively involved in commercial real estate lending should perform a risk assessment to identify concentrations. A financial institution may have a concentration in commercial real estate lending if, among other factors (i) total reported loans for construction, land development and other land represent 100% or more of total capital, or (ii) total reported loans secured by multi-family and non-farm non-residential properties, loans for construction, land development and other land, and loans otherwise sensitive to the general commercial real estate market, including loans to commercial real estate related entities, represent 300% or more of total capital. The particular focus of the guidance is on exposure to commercial real estate loans that are dependent on the cash flow from the real estate held as collateral and that are likely to be at greater risk to conditions in the commercial real estate market (as opposed to real estate collateral held as a secondary source of repayment or as an abundance of caution).  The purpose of the guidance is to guide banks in developing risk management practices and capital levels commensurate with the level and nature of real estate concentrations.  The guidance states that management should employ heightened risk management practices including board and management oversight and strategic planning, development of underwriting standards, risk assessment and monitoring through market analysis and stress testing. We have concluded that we have a concentration in commercial real estate lending because our balance in commercial real estate loans (including owner-occupied loans) at September 30, 2020 represents more than 300% of total capital. While we believe we have implemented policies and procedures with respect to our commercial real estate loan portfolio consistent with this guidance, bank regulators could require us to implement additional policies and procedures consistent with their interpretation of the guidance that may result in additional costs to us.

40

Repayment of our commercial business loans is often dependent on the cash flows of the borrower, which may be unpredictable, and the collateral securing these loans may fluctuate in value.

At September 30, 2020, we had $69.54 million, or 6.1%, of total loans in commercial business loans (excluding SBA PPP loans).  Commercial business lending involves risks that are different from those associated with residential and commercial real estate lending. Real estate lending is generally considered to be collateral based lending with loan amounts based on predetermined loan to collateral values and liquidation of the underlying real estate collateral being viewed as the primary source of repayment in the event of borrower default. Our commercial business loans are primarily made based on the cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The borrowers' cash flow may be unpredictable, and collateral securing these loans may fluctuate in value. Although commercial business loans are often collateralized by equipment, inventory, accounts receivable, or other business assets, the liquidation of collateral in the event of default is often an insufficient source of repayment because accounts receivable may be uncollectible and inventories may be obsolete or of limited use, among other things.  Accordingly, the repayment of commercial business loans depends primarily on the cash flow and credit worthiness of the borrower and secondarily on the underlying collateral provided by the borrower.

Our business may be adversely affected by credit risk associated with residential property.

At September 30, 2020, $150.66 million, or 13.3%, of our total loan portfolio was secured by one- to four-family mortgage loans and home equity loans.  This type of lending is generally sensitive to regional and local economic conditions that significantly impact the ability of borrowers to meet their loan payment obligations, making loss levels difficult to predict. Recessionary conditions or declines in the volume of single-family real estate and/or the sales prices as well as elevated unemployment rates may result in higher than expected loan delinquencies or problem assets, and a decline in demand for our products and services. These potential negative events may cause us to incur losses, adversely affect our capital and liquidity and damage our financial condition and business operations. Further, a decline in residential real estate values resulting from a downturn in the Washington housing market may reduce the value of the real estate collateral securing these types of loans and increase our risk of loss if borrowers default on their loans.

Many of our residential mortgage loans are secured by liens on mortgage properties in which the borrowers have little or no equity because either we originated the loan with a relatively high combined loan-to-value ratio or because of the decline in home values in our market areas subsequent to when the loans were originated.  Residential loans with combined higher loan-to-value ratios will be more sensitive to declining property values than those with lower combined loan-to-value ratios and therefore may experience a higher incidence of default and severity of losses. In addition, if the borrowers sell their homes, such borrowers may be unable to repay their loans in full from the sale proceeds.  Further, a significant amount of our home equity lines of credit consist of second mortgage loans. For those home equity lines secured by a second mortgage, it is unlikely that we will be successful in recovering all or a portion of our loan proceeds in the event of default unless we are prepared to repay the first mortgage loan and such repayment and the costs associated with a foreclosure are justified by the value of the property.  For these reasons, we may experience higher rates of delinquencies, default and losses on our residential loans.

Our allowance for loan losses may prove to be insufficient to absorb losses in our loan portfolio.

Lending money is a substantial part of our business, and each loan carries a certain risk that it will not be repaid in accordance with its terms or that any underlying collateral will not be sufficient to assure repayment. This risk is affected by, among other things:

•the cash flow of the borrower and/or the project being financed;

•the changes and uncertainties as to the future value of the collateral, in the case of a collateralized loan;

•the duration of the loan;

•the credit history of a particular borrower; and

•changes in economic and industry conditions.

We maintain an allowance for loan losses, which is a reserve established through a provision for loan losses charged against operating income, which we believe is appropriate to provide for probable losses in our loan portfolio. The amount of this allowance is determined by our management through periodic comprehensive reviews and consideration of several factors, including, but not limited to:

•an ongoing review of the quality, size and diversity of the loan portfolio;

•evaluation of non-performing loans;

•historical default and loss experience;

•existing economic conditions and management's expectations of future events;

•risk characteristics of the various classifications of loans;

41

•the amount and quality of collateral, including guarantees, securing the loans; and

•regulatory requirements and expectations.

The determination of the appropriate level of the allowance for loan losses inherently involves a high degree of subjectivity and requires us to make various assumptions and judgments about the collectability of our loan portfolio, including the creditworthiness of our borrowers and the value of the real estate and other assets serving as collateral for the repayment of many of our loans. In determining the amount of the allowance for loan losses, we review our loans and the loss experience and evaluate economic conditions and make significant estimates of current credit risks and future trends, all of which may undergo material changes. If our estimates are incorrect, the allowance for loan losses may not be sufficient to cover losses inherent in our loan portfolio, resulting in the need for increases in our allowance for loan losses through the provision for losses on loans which is charged against income. Management also recognizes that significant new growth in loan portfolios, new loan products and the refinancing of existing loans can result in portfolios comprised of unseasoned loans that may not perform in a historical or projected manner and will increase the risk that our allowance may be insufficient to absorb losses without significant additional provisions. Further, the Financial Accounting Standards Board has adopted a new accounting standard that will be effective for our fiscal year beginning October 1, 2023. This standard, referred to as Current Expected Credit Loss ("CECL") will require financial institutions to determine periodic estimates of lifetime expected credit losses on loans, and recognize the expected credit losses as allowances for credit losses. This will change the current method of providing allowances for credit losses that are probable. We anticipate that our allowance for loan losses will increase as a result of the implementation of CECL, however, until our evaluation is complete, the magnitude of the increase will be unknown.

Deterioration in economic conditions affecting borrowers, new information regarding existing loans, identification of additional problem loans and other factors, both within and outside of our control, may also require an increase in the allowance for loan losses.  In addition, bank regulatory agencies periodically review our allowance for loan losses and may require an increase in the provision for possible loan losses or the recognition of further loan charge-offs, based on judgments different from those of management. If charge-offs in future periods exceed the allowance for loan losses, we will need additional provisions to replenish the allowance for loan losses.  Any additional provisions will result in a decrease in net income and possibly capital, and may have a material adverse effect on our financial condition and results of operations.

If our non-performing assets increase, our earnings will be adversely affected.

At September 30, 2020 our non-performing assets (which consist of non-accruing loans, accruing loans 90 days or more past due, non-accrual investment securities, and OREO and other repossessed assets) were $4.16 million, or 0.27% of total assets. Our non-performing assets adversely affect our net income in various ways:

•We do not record interest income on non-accrual loans or non-performing investment securities, except on a cash basis when the collectibility of the principal is not in doubt.

•We must provide for probable loan losses through a current period charge to the provision for loan losses.

•Non-interest expense increases when we must write down the value of properties in our OREO portfolio to reflect changing market values.

•Non-interest income decreases when we must recognize other-than-temporary impairment on non-performing investment securities.

•There are legal fees associated with the resolution of problem assets, as well as carrying costs, such as taxes, insurance, and maintenance costs related to our OREO.

•The resolution of non-performing assets requires the active involvement of management, which can distract them from more profitable activity.

If additional borrowers become delinquent and do not pay their loans and we are unable to successfully manage our non-performing assets, our losses and troubled assets could increase significantly, which could have a material adverse effect on our financial condition and results of operations. In addition to the non-performing loans, there were $2.87 million in loans classified as performing troubled debt restructurings at September 30, 2020.

Risk Related to our Business Strategy

We may be adversely affected by risks associated with completed and potential acquisitions.

As part of our general growth strategy, on October 1, 2018 we completed the acquisition of South Sound Bank, a Washington-state chartered bank, headquartered in Olympia, Washington. Although our business strategy emphasizes organic expansion, we continue, from time to time in the ordinary course of business, to engage in preliminary discussions with potential acquisition targets. There can be no assurance that, in the future, we will successfully identify suitable acquisition candidates,

42

complete acquisitions and successfully integrate acquired operations into our existing operations or expand into new markets. The consummation of any future acquisitions may dilute shareholder value or may have an adverse effect upon our operating results while the operations of the acquired business are being integrated into our operations. In addition, once integrated, acquired operations may not achieve levels of profitability comparable to those achieved by our existing operations, or otherwise perform as expected. Further, transaction-related expenses may adversely affect our earnings. These adverse effects on our earnings and results of operations may have a negative impact on the value of our common stock. Acquiring banks, bank branches or businesses involves risks commonly associated with acquisitions, including:

•We may be exposed to potential asset quality issues or unknown or contingent liabilities of the banks, businesses, assets, and liabilities we acquire. If these issues or liabilities exceed our estimates, our results of operations and financial condition may be materially negatively affected;

•Higher than expected deposit attrition;

•The acquisition of other entities generally requires integration of systems, procedures and personnel of the acquired entity into our company to make the transaction economically successful. This integration process is complicated and time consuming and can also be disruptive to the customers of the acquired business. If the integration process is not conducted successfully and with minimal adverse effect on the acquired business and its customers, we may not be able to realize the anticipated economic benefits of particular acquisitions within the expected time frame, and we may lose customers or employees of the acquired business. We may also experience greater than anticipated customer losses even if the integration process is successful;

•To the extent our costs of an acquisition exceed the fair value of the net assets acquired, the acquisition will generate goodwill. As discussed below, we are required to assess our goodwill for impairment at least annually, and any goodwill impairment charge could have a material adverse effect on our results of operation and financial condition;

•We expect our net income will increase following an acquisition; however, we also expect our general and administrative expenses to increase, which could result to an increase in our efficiency ratio. Ultimately, we would expect our efficiency ratio to improve; however, if we are not successful in our integration process, this may not occur, and our acquisition or branching activities may not be accretive to earnings in the short or long-term.

Risk Related to Market Interest Rates

Fluctuating interest rates can adversely affect our profitability

Our earnings and cash flows are largely dependent upon our net interest income. Interest rates are highly sensitive to many factors that are beyond our control, including general economic conditions and policies of various governmental and regulatory agencies and, in particular, the Federal Reserve Board. After steadily increasing the target federal funds rate in 2018 and 2017, the Federal Reserve Board in 2019 decreased the target federal funds rate by 75 basis points, and in response to the COVID-19 pandemic in March 2020, an additional 150 basis point decrease to a range of 0.00% to 0.25% as of March 31, 2020. The Federal Reserve Board could make additional changes during 2020 subject to economic conditions. If the Federal Reserve Board increases the Fed Funds rate, overall interest rates will likely rise, which may negatively impact both the housing markets by reducing refinancing activity and new home purchases and the U.S. economy. In addition, deflationary pressures, while possibly lowering our operational costs, could have a significant negative effect on our borrowers, especially our business borrowers, and the values of collateral securing loans which could negatively affect our financial performance.

We principally manage interest rate risk by managing our volume and mix of our earning assets and funding liabilities. Changes in monetary policy, including changes in interest rates, could influence not only the interest we receive on loans and investments and the amount of interest we pay on deposits and borrowings, but these changes could also affect: (1) our ability to originate and/or sell loans and obtain deposits; (2) the fair value of our financial assets and liabilities, which could negatively impact shareholders’ equity, and our ability to realize gains from the sale of such assets; (3) our ability to obtain and retain deposits in competition with other available investment alternatives; (4) the ability of our borrowers to repay adjustable or variable rate loans; and (5) the average duration of our investment securities portfolio and other interest-earning assets.  If the interest rates paid on deposits and borrowings increase at a faster rate than the interest received on loans and other investments, our net interest income, and therefore earnings, could be adversely affected. Earnings could also be adversely affected if the interest rates received on loans and other investments decline more rapidly than the interest rates paid on deposits and other borrowings. In a changing interest rate environment, we may not be able to manage this risk effectively. If we are unable to manage interest rate risk effectively, our business, financial condition and results of operations could be materially affected.

Changes in interest rates could also have a negative impact on our results of operations by reducing the ability of borrowers to repay their current loan obligations or by reducing our margins and profitability. Our net interest margin is the difference between the yield we earn on our assets and the interest rate we pay for deposits and our other sources of funding. Changes in interest rates (up or down) could adversely affect our net interest margin and, as a result, our net interest income. Although the yield we earn on our assets and our funding costs tends to move in the same direction in response to changes in

43

interest rates, one can rise or fall faster than the other, causing our net interest margin to expand or contract. Changes in the slope of the "yield curve", or the spread between short-term and long-term interest rates, could also reduce our net interest margin. Normally the yield curve is upward sloping, meaning short-term rates are lower than long-term rates. Because our liabilities tend to be shorter in duration than our assets, when the yield curve flattens or even inverts, we could experience pressure on our net interest margin as our cost of funds increases relative to the yield we can earn on our assets. Also, interest rate decreases can lead to increased prepayments of loans and mortgage-backed securities as borrowers refinance their loans to reduce borrowing costs. Under these circumstances we are subject to reinvestment risk as we may have to redeploy such repayment proceeds into lower yielding investments, which would likely negatively impact our income.

A sustained increase or decrease in market interest rates could adversely affect our earnings. As is the case with many financial institutions, our emphasis on increasing the development of core deposits, those deposits bearing no or a relatively low rate of interest with no stated maturity, has resulted in our having a significant amount of these deposits bearing a relatively low rate of interest and having a shorter duration than our assets. At September 30, 2020, we had $102.86 million in certificates of deposit that mature within one year and $1.20 billion in non-interest bearing, NOW checking, savings and money market accounts. We would incur a higher cost of funds to retain these deposits in a rising interest rate environment. If the interest rates paid on deposits and other borrowings increase at a faster rate than the interest rates received on loans and other investments, our net interest income, and therefore earnings, could be adversely affected. In addition, a substantial amount of our residential mortgage loans and home equity lines of credit have adjustable interest rates. As a result, these loans may experience a higher rate of default in a rising interest rate environment.

Changes in interest rates also affect the value of our interest-earning assets and in particular our investment securities portfolio. Generally, the fair value of fixed-rate securities fluctuates inversely with changes in interest rates. Unrealized gains and losses on investment securities available for sale are reported as a separate component of equity, net of tax. Decreases in the fair value of investment securities available for sale resulting from increases in interest rates could have an adverse effect on stockholders' equity.

Any substantial, unexpected or prolonged change in market interest rates could have a material adverse effect on our financial condition, liquidity and results of operations. Also, our interest rate risk modeling techniques and assumptions likely may not fully predict or capture the impact of actual interest rate changes on our balance sheet or projected operating results. In this regard, because the length of the COVID-19 pandemic and the efficacy of the extraordinary measures being put in place to address its economic consequences are unknown, including the recent 150 basis point reductions in the targeted federal funds rate, until the pandemic subsides, the Company expects its net interest income and net interest margin will be adversely affected. For further discussion of how changes in interest rates could impact us, see "Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk" for additional information about our interest rate risk management.

Our investment securities portfolio may be negatively impacted by fluctuations in market value and interest rates and result in losses.

Our investment securities portfolio may be impacted by fluctuations in market value, potentially reducing accumulated other comprehensive income (loss) and/or earnings. Fluctuations in market value may be caused by changes in market interest rates, lower market prices for investment securities and limited investor demand. Our held to maturity and available for sale investment securities are evaluated for other-than-temporary-impairment ("OTTI"). If this evaluation shows impairment to the actual or projected cash flows associated with one or more investment securities, a potential loss to earnings may occur. Changes in interest rates can also have an adverse effect on our financial condition, as our available-for-sale investment securities are reported at their estimated fair value, and therefore are impacted by fluctuations in interest rates. We increase or decrease our shareholders' equity by the amount of change in the estimated fair value of the available-for-sale investment securities, net of income taxes. There can be no assurance that the declines in market value, including as a result of the COVID-19 pandemic, will not result in OTTI of these assets, which would lead to accounting charges that could have a material adverse effect on our net income and capital levels.

During the year ended September 30, 2020, we recognized a $120,000 recovery of OTTI charges on private label mortgage backed securities we hold for investment. During the year ended September 30, 2019, we recognized a $59,000 recovery of OTTI charges on private label mortgage backed securities we hold for investment. During the year ended September 30, 2018, we recognized a $68,000 recovery of OTTI charges on private label mortgage backed securities we hold for investment. At September 30, 2020, our remaining private label mortgage backed securities portfolio totaled $229,000 of which $209,000 was on non-accrual status.

The valuation of our investment securities also is influenced by additional external market and other factors, including implementation of Securities and Exchange Commission and Financial Accounting Standards Board guidance on fair value accounting, default rates on residential mortgage securities and rating agency actions. Accordingly, there can be no assurance

44

that future declines in the market value of our private label mortgage backed securities or other investment securities will not result in additional OTTI of these assets and lead to accounting charges that could have an adverse effect on our results of operations.

An increase in interest rates, change in the programs offered by Freddie Mac or our ability to qualify for their programs may reduce our mortgage revenues, which would negatively impact our non-interest income.

The sale of residential mortgage loans to Freddie Mac provides a significant portion of our non-interest income. Any future changes in their program, our eligibility to participate in such program, the criteria for loans to be accepted or laws that significantly affect the activity of Freddie Mac could, in turn, materially adversely affect our results of operations if we could not find other purchasers. Mortgage banking is generally considered a volatile source of income because it depends largely on the level of loan volume which, in turn, depends largely on prevailing market interest rates. In a rising or higher interest rate environment, the demand for mortgage loans, particularly refinancing of existing mortgage loans, tends to fall and our originations of mortgage loans may decrease, resulting in fewer loans that are available to be sold. This would result in a decrease in mortgage revenues and a corresponding decrease in non-interest income. In addition, our results of operations are affected by the amount of non-interest expense associated with our loan sale activities, such as salaries and employee benefits, occupancy, equipment and data processing expense and other operating costs. During periods of reduced loan demand, our results of operations may be adversely affected to the extent that we are unable to reduce expenses commensurate with the decline in loan originations. In addition, although we sell loans to Freddie Mac or into the secondary market without recourse, we are required to give customary representations and warranties about the loans we sell. If we breach those representations and warranties, we may be required to repurchase the loans and we may incur a loss on the repurchase.

Risks Related to Laws and Regulations

We operate in a highly regulated environment and may be adversely affected by changes in federal and state laws and regulations that could increase our costs of operations.

The banking industry is extensively regulated. Federal banking regulations are designed primarily to protect the deposit insurance funds and consumers, not to benefit a company's shareholders. These regulations may sometimes impose significant limitations on our operations. Certain significant federal and state banking regulations that affect us are described in this report under the heading "Item 1. Business-How We Are Regulated". These regulations, along with the currently existing tax, accounting, securities, insurance, and monetary laws, regulations, rules, standards, policies, and interpretations control the methods by which financial institutions conduct business, implement strategic initiatives and tax compliance, and govern financial reporting and disclosures. These laws, regulations, rules, standards, policies, and interpretations are constantly evolving and may change significantly over time. Any new regulations or legislation, change in existing regulation or oversight, whether a change in regulatory policy or a change in a regulator's interpretation of a law or regulation, could have a material impact on our operations, increase our costs of regulatory compliance and of doing business and adversely affect our profitability. In this regard, the U.S. Department of the Treasury's Financial Crimes Enforcement Network ("FinCEN"), published guidelines in 2014 for financial institutions servicing marijuana businesses that are legal under state law. These guidelines allow us to work with marijuana-related businesses that are operating in accordance with state laws and regulations, so long as we comply with required regulatory oversight of their accounts with us. In addition, legislation is currently pending in Congress that would allow banks and financial institutions to serve marijuana businesses in states where it is legal without any risk of federal prosecution. At September 30, 2020, approximately 2.6% of our total deposits and a portion of our service charges from deposits are from legal marijuana-related businesses. Any adverse change in this FinCEN guidance, any new regulations or legislation, any change in existing regulations or oversight, whether a change in regulatory policy or a change in a regulator's interpretation of a law or regulation, could have a negative impact on our non-interest income, as well as the cost of our operations, increasing our cost of regulatory compliance and of doing business and/or otherwise affect us, which may materially affect our profitability.

Non-compliance with the USA PATRIOT Act, Bank Secrecy Act, or other laws and regulations could result in fines or sanctions and limit our ability to get regulatory approval of acquisitions.

The USA PATRIOT and Bank Secrecy Acts require financial institutions to develop programs to prevent financial institutions from being used for money laundering and terrorist activities. If such activities are detected, financial institutions are obligated to file suspicious activity reports with FinCEN. These rules require financial institutions to establish procedures for identifying and verifying the identity of customers seeking to open new financial accounts. Failure to comply with these regulations could result in fines or sanctions and limit our ability to get regulatory approval of acquisitions. Recently several banking institutions have received large fines for non-compliance with these laws and regulations. While we have developed policies and procedures designed to assist in compliance with these laws and regulations, no assurance can be given that these policies and procedures will be effective in preventing violations of these laws and regulations.

Risks Related to Cybersecurity, Third Parties and Technology

The financial services market is undergoing rapid technological changes, and if we are unable to stay current with those changes, we may not be able to effectively compete.

The financial services market, including banking services, is undergoing rapid changes with frequent introductions of new technology-driven products and services. Our future success will depend, in part, on our ability to keep pace with the technological changes and to use technology to satisfy and grow customer demand for our products and services and to create additional efficiencies in our operations. We expect that we will need to make substantial investments in our technology and information systems to compete effectively and to stay current with technological changes. Some of our competitors have substantially greater resources to invest in technological improvements and will be able to invest more heavily in developing and adopting new technologies, which may put us at a competitive disadvantage. We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers. As a result, our ability to effectively compete to retain or acquire new business may be impaired, and our business, financial condition or results of operations may be adversely affected.

We are subject to certain risks in connection with our use of technology.

Our security measures may not be sufficient to mitigate the risk of a cyber attack. Communications and information systems are essential to the conduct of our business, as we use such systems to manage our customer relationships, our general ledger and virtually all other aspects of our business. Our operations rely on the secure processing, storage, and transmission of confidential and other information in our computer systems and networks. Although we take protective measures and endeavor to modify them as circumstances warrant, the security of our computer systems, software, and networks may be vulnerable to breaches, fraudulent or unauthorized access, denial or degradation of service attacks, misuse, computer viruses, malware or other malicious code and cyber attacks that could have a security impact. If one or more of these events occur, this could jeopardize our or our customers' confidential and other information processed and stored in, and transmitted through, our computer systems and networks, or otherwise cause interruptions or malfunctions in our operations or the operations of our customers or counterparties. We may be required to expend significant additional resources to modify our protective measures or to investigate and remediate vulnerabilities or other exposures, and we may be subject to litigation and financial losses that are either not insured against or not fully covered through any insurance maintained by us. We could also suffer significant reputational damage.

Security breaches in our internet banking activities could further expose us to possible liability and damage our reputation. Increases in criminal activity levels and sophistication, advances in computer capabilities, new discoveries, vulnerabilities in third party technologies (including browsers and operating systems) or other developments could result in a compromise or breach of the technology, processes and controls that we use to prevent fraudulent transactions and to protect data about us, our clients and underlying transactions. Any compromise of our security could deter customers from using our internet banking services that involve the transmission of confidential information. We rely on standard internet security systems to provide the security and authentication necessary to effect secure transmission of data. Although we have developed and continue to invest in systems and processes that are designed to detect and prevent security breaches and cyber attacks and periodically test our security, these precautions may not protect our systems from compromises or breaches of our security measures, and could result in losses to us or our customers, our loss of business and/or customers, damage to our reputation, the incurrence of additional expenses, disruption to our business, our inability to grow our online services or other businesses, additional regulatory scrutiny or penalties, or our exposure to civil litigation and possible financial liability, any of which could have a material adverse effect on our business, financial condition and results of operation.

Our security measures may not protect us from system failures or interruptions. While we have established policies and procedures to prevent or limit the impact of systems failures and interruptions, there can be no assurance that such events will not occur or that they will be adequately addressed if they do. In addition, we outsource certain aspects of our data processing and other operational functions to certain third-party providers. While the Company selects third-party vendors carefully, it does not control their actions. If our third-party providers encounter difficulties, including those resulting from breakdowns, or other disruptions in communication services provided by a vendor, failure of a vendor to handle current or higher transaction volumes, cyber-attacks and security breaches or if we otherwise have difficulty in communicating with them, our ability to adequately process and account for transactions could be affected, and our ability to deliver products and services to our customers and otherwise conduct business operations could be adversely impacted. Replacing these third-party vendors could also entail significant delay and expense. Threats to information security also exist in the processing of customer information through various other vendors and their personnel.

We cannot assure you that such breaches, failures or interruptions will not occur or, if they do occur, that they will be adequately addressed by us or the third parties on which we rely. We may not be insured against all types of losses as a result

46

of third-party failures and insurance coverage may be inadequate to cover all losses, resulting from breaches, systems failures or other disruptions. If any of our third party service providers experience financial, operational or technological difficulties, or if there is any other disruption in our relationships with them, we may be required to identify alternative sources of such services, and we cannot assure you that we could negotiate terms that are as favorable to us or could obtain services with similar functionality as found in our existing systems without the need to expend substantial resources, if at all. Further, the occurrence of any systems failure or interruption could damage our reputation and result in a loss of customers and business, could subject us to additional regulatory scrutiny, or could expose us to legal liability. Any of these occurrences could have a material adverse effect on our financial condition and results of operations.

The board of directors oversees the risk management process, including the risk of cybersecurity, and engages with management on cybersecurity issues.

Our business may be adversely affected by an increasing prevalence of fraud and other financial crimes.

As a bank, we are susceptible to fraudulent activity that may be committed against us or our customers which may result in financial losses or increased costs to us or our customers, disclosure or misuse of our information or our customers' information, misappropriation of assets, privacy breaches against our customers, litigation or damage to our reputation. Such fraudulent activity may take many forms, including check fraud, electronic fraud, wire fraud, phishing, social engineering and other dishonest acts. Nationally, reported incidents of fraud and other financial crimes have increased. We have also experienced losses due to apparent fraud and other financial crimes. While we have policies and procedures designed to prevent such losses, there can be no assurance that such losses will not occur.

Managing reputational risk is important to attracting and maintaining customers, investors and employees.

Threats to our reputation can come from many sources, including adverse sentiment about financial institutions generally, unethical practices, employee misconduct, failure to deliver minimum standards of service or quality, compliance deficiencies and questionable or fraudulent activities of our customers. We have policies and procedures in place to protect our reputation and promote ethical conduct, but these policies and procedures may not be fully effective. Negative publicity regarding our business, employees, or customers, with or without merit, may result in the loss of customers, investors and employees, costly litigation, a decline in revenues and increased governmental regulation.

We rely on other companies to provide key components of our business infrastructure.

We rely on numerous external vendors to provide us with products and services necessary to maintain our day-to-day operations. Accordingly, our operations are exposed to risk that these vendors will not perform in accordance with the contracted arrangements under service level agreements. The failure of an external vendor to perform in accordance with the contracted arrangements under service level agreements because of changes in the vendor's organizational structure, financial condition, support for existing products and services or strategic focus or for any other reason, could be disruptive to our operations, which in turn could have a material negative impact on our financial condition and results of operations. We also could be adversely affected to the extent such an agreement is not renewed by a third party vendor or is renewed on terms less favorable to us. Additionally, the bank regulatory agencies expect financial institutions to be responsible for all aspects of our vendors' performance, including aspects which they delegate to third parties. Disruptions or failures in the physical infrastructure or operating systems that support our business and customers, or cyber-attacks or security breaches of the networks, systems or devices that our customers use to access our products and services could result in client attrition, regulatory fines, penalties or intervention, reputational damage, reimbursement or other compensation costs, and/or additional compliance costs, any of which could materially adversely affect our results of operations or financial condition.

Risks Related to Accounting Matters

We may experience future goodwill impairment, which could reduce our earnings.

We performed our test for goodwill impairment for fiscal year 2020, and the test concluded that recorded goodwill was not impaired. Our test of goodwill for potential impairment is based on a qualitative assessment by management that takes into consideration macroeconomic conditions, industry and market conditions, cost or margin factors, financial performance and share price. Our evaluation of the fair value of goodwill involves a substantial amount of judgment. If our judgment was incorrect, or if events or circumstances change, and an impairment of goodwill was deemed to exist, we would be required to write down our goodwill resulting in a charge against operations, which would adversely affect our results of operations, perhaps materially; however, it would have no impact on our liquidity, operations or regulatory capital. The acquisition of South Sound Bank on October 1, 2018 substantially increased our goodwill.

47

We may experience decreases in the fair value of our servicing rights, which could reduce our earnings.

Servicing rights are capitalized at estimated fair value when acquired through the origination of loans that are subsequently sold with servicing rights retained.  At September 30, 2020, our servicing rights totaled $3.10 million (including a valuation allowance of $229,000).  Servicing rights are amortized to servicing income on loans sold over the period of estimated net servicing income.  The estimated fair value of servicing rights at the date of the sale of loans is determined based on the discounted present value of expected future cash flows using key assumptions for servicing income and costs and prepayment rates on the underlying loans.  On a quarterly basis, we evaluate the fair value of servicing rights for impairment by comparing actual cash flows and estimated cash flows from the servicing assets to those estimated at the time servicing assets were originated.  Our methodology for estimating the fair value of servicing rights is highly sensitive to changes in assumptions, such as prepayment speeds.  The effect of changes in market interest rates on estimated rates of loan prepayments represents the predominant risk characteristic underlying the servicing rights portfolio.  For example, a decrease in interest rates typically increases the prepayment speeds of servicing rights and therefore decreases the fair value of the servicing rights.  Future decreases in interest rates could decrease the fair value of our servicing rights below their recorded amount, which would decrease our earnings.

The required accounting treatment of loans we acquire through acquisitions including purchase credit impaired loans could result in higher net interest margins and interest income in current periods and lower net interest margins and interest income in future periods.

Under GAAP, we are required to record loans acquired through acquisitions, including purchase credit impaired loans, at fair value. Estimating the fair value of such loans requires management to make estimates based on available information and facts and circumstances on the acquisition date. Actual performance could differ from management’s initial estimates. If these loans outperform our original fair value estimates, the difference between our original estimate and the actual performance of the loan (the “discount”) is accreted into net interest income. Thus, our net interest margins may initially increase due to the discount accretion. We expect the yields on our loans to decline as our acquired loan portfolio pays down or matures and the discount decreases, and we expect downward pressure on our interest income to the extent that the runoff on our acquired loan portfolio is not replaced with comparable high-yielding loans. This could result in higher net interest margins and interest income in current periods and lower net interest margins and lower interest income in future periods.

If our investments in real estate are not properly valued or sufficiently reserved to cover actual losses, or if we are required to increase our valuation allowances, our earnings could be reduced.

We obtain updated valuations in the form of appraisals and broker price opinions when a loan has been foreclosed and the property is taken in as OREO, and at certain other times during the asset's holding period.  Our net book value (“NBV”) in the loan at the time of foreclosure and thereafter is compared to the updated estimated market value of the foreclosed property less estimated selling costs (fair value). A charge-off is recorded for any excess in the asset’s NBV over its fair value.  If our valuation process is incorrect or if the property declines in value after foreclosure, the fair value of our OREO may not be sufficient to recover our NBV in such assets, resulting in the need for a valuation allowance.

In addition, bank regulators periodically review our OREO and may require us to recognize further valuation allowances.  Significant charge-offs to our OREO may have a material adverse effect on our financial condition and results of operations.

Other Risks Related to Our Business

Ineffective liquidity management could adversely affect our financial results and condition.

Effective liquidity management is essential to our business. We require sufficient liquidity to meet customer loan requests, customer deposit maturities and withdrawals, payments on our debt obligations as they come due and other cash commitments under both normal operating conditions and other unpredictable circumstances, including events causing industry or general financial market stress. An inability to raise funds through deposits, borrowings, the sale of loans and other sources could have a substantial negative effect on our liquidity. We rely on customer deposits and at times, borrowings from the FHLB, borrowings from the FRB and other borrowings to fund our operations. At September 30, 2020, we had $10.00 million in outstanding FHLB borrowings and an additional $435.99 million of available borrowing capacity through the FHLB and the FRB. Deposit flows and the prepayment of loans and mortgage-related securities are strongly influenced by such external factors as the direction of interest rates, whether actual or perceived, and the competition for deposits and loans in the markets we serve. Further, changes to the FHLB's underwriting guidelines for wholesale borrowings or lending policies may limit or restrict our ability to borrow, and could therefore have a significant adverse impact on our liquidity.  Although we have historically been able to replace maturing deposits and borrowings if desired, we may not be able to replace such funds in the

48

future if, among other things, our financial condition, the financial condition of the FHLB or FRB, or market conditions change. Our access to funding sources in amounts adequate to finance our activities or on terms which are acceptable could be impaired by factors that affect us specifically or the financial services industry or economy in general, such as a disruption in the financial markets or negative views and expectations about the prospects for the financial services industry. Additional factors that could detrimentally impact our access to liquidity sources include a decrease in the level of our business activity as a result of a downturn in the Washington markets where our deposits are concentrated or adverse regulatory action against us.

Our financial flexibility will be severely constrained if we are unable to maintain our access to funding or if adequate financing is not available to accommodate future growth at acceptable interest rates. Although we consider our sources of funds adequate for our liquidity needs, we may seek additional debt in the future to achieve our long-term business objectives. Additional borrowings, if sought, may not be available to us or, if available, may not be available on reasonable terms. If additional financing sources are unavailable, or are not available on reasonable terms, our financial condition, results of operations, growth and future prospects could be materially adversely affected. Finally, if we are required to rely more heavily on more expensive funding sources to support future growth, our income may not increase proportionately to cover our costs.

Our growth or future losses may require us to raise additional capital in the future, but that capital may not be available when it is needed or the cost of that capital may be very high.

We are required by federal regulatory authorities to maintain adequate levels of capital to support our operations.  Our ability to raise additional capital, if needed, will depend on conditions in the capital markets at that time, which are outside our control, and on our financial condition and performance.  If we are able to raise capital it may not be on terms that are acceptable to us.  Accordingly, we cannot make assurances that we will be able to raise additional capital if needed on terms that are acceptable to us, or at all.  If we cannot raise additional capital when needed, our ability to further expand our operations could be materially impaired and our financial condition and liquidity could be materially and adversely affected. In addition, any additional capital we obtain may result in the dilution of the interests of existing holders of our common stock. Further, if we are unable to raise additional capital when required by our bank regulators, we may be subject to adverse regulatory action. 

Our framework for managing risks may not be effective in mitigating risk and loss to us.

We have established processes and procedures intended to identify, measure, monitor, report, analyze and control the types of risk to which we are subject. These risks include liquidity risk, credit risk, market risk, interest rate risk, operational risk, legal and compliance risk, and reputational risk, among others. We also maintain a compliance program to identify, measure, assess, and report on our adherence to applicable laws, policies and procedures. While we assess and improve these programs on an ongoing basis, there can be no assurance that our risk management or compliance programs, along with other related controls, will effectively mitigate all risk and limit losses in our business. As with any risk management framework, there are inherent limitations to our risk management strategies as there may exist, or develop in the future, risks that we have not appropriately anticipated or identified. If our risk management framework proves ineffective, we could suffer unexpected losses which could have a material adverse effect on our financial condition and results of operations.

We are dependent on key personnel, and the loss of one or more of those key personnel may materially and adversely affect our prospects.

Competition for qualified employees and personnel in the banking industry is intense, and there are a limited number of qualified persons with knowledge of, and experience in, the community banking industry where the Bank conducts its business. The process of recruiting personnel with the combination of skills and attributes required to carry out our strategies is often lengthy. Our success depends to a significant degree upon our ability to attract and retain qualified management, loan origination, finance, administrative, marketing and technical personnel and upon the continued contributions of our management and personnel.  In particular, our success has been and continues to be highly dependent upon the abilities of key executives, including our President, and certain other employees.  In addition, our success has been and continues to be highly dependent upon the services of our directors, and we may not be able to identify and attract suitable candidates to replace such directors.

Uncertainty relating to the London Interbank Offered Rate ("LIBOR") calculation process and potential phasing out of LIBOR may adversely affect our results of operations.

On July 27, 2017, the Chief Executive of the United Kingdom Financial Conduct Authority, which regulates LIBOR, announced that it intends to stop persuading or compelling banks to submit rates for the calibration of LIBOR to the administrator of LIBOR after 2021. The announcement indicates that the continuation of LIBOR on the current basis cannot and will not be guaranteed after 2021. It is impossible to predict whether and to what extent banks will continue to provide

49

LIBOR submissions to the administrator of LIBOR or whether any additional reforms to LIBOR may be enacted in the United Kingdom or elsewhere. At this time, no consensus exists as to what rate or rates may become acceptable alternatives to LIBOR and it is impossible to predict the effect of any such alternatives on the value of LIBOR-based securities and variable rate loans, or other securities or financial arrangements, given LIBOR's role in determining market interest rates globally. The Federal Reserve Board, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, is considering replacing the U.S. dollar LIBOR with a new index calculated by short-term repurchase agreements, backed by Treasury securities ("SOFR"). SOFR is observed and backward looking, which stands in contrast with LIBOR under the current methodology, which is an estimated forward-looking rate and relies, to some degree, on the expert judgment of submitting panel members. Given that SOFR is a secured rate backed by government securities, it will be a rate that does not take into account bank credit risk (as is the case with LIBOR). SOFR is therefore likely to be lower than LIBOR and is less likely to correlate with the funding costs of financial institutions. Whether or not SOFR attains traction as a LIBOR replacement tool remains in question, although transactions using SOFR have been completed including by Fannie Mae. Both Fannie Mae and Freddie Mac have recently announced that they will cease accepting adjustable rate mortgages tied to LIBOR by the end of 2020 and will soon begin accepting mortgages based on SOFR. Continued uncertainty as to the nature of alternative reference rates and as to potential changes or other reforms to LIBOR may adversely affect LIBOR rates and the value of LIBOR-based loans, and securities in our portfolio. If LIBOR rates are no longer available, and we are required to implement substitute indices for the calculation of interest rates under our loan agreements with our borrowers, we may experience significant expenses in effecting the transition, and may be subject to disputes or litigation with customers and creditors over the appropriateness or comparability to LIBOR of the substitute indices, which could have an adverse effect on our results of operations.

Stock Repurchases

The Company is subject to certain restrictions on its ability to repurchase its common stock. The Company is required to give the Federal Reserve prior written notice of any purchase or redemption of its outstanding equity securities if the consideration for the purchase or redemption, when combined with the net consideration paid for all such purchases or redemptions during the preceding 12 months, is equal to 10% or more of its consolidated net worth. The Federal Reserve may disapprove a purchase or redemption if it determines that the proposal would constitute an unsafe or unsound practice or would violate any law, regulation, Federal Reserve order, or any condition imposed by, or written agreement with, the Federal Reserve.  

The Company has had various stock repurchase programs since January 1998. On July 28, 2015, the Company announced a plan to repurchase 352,681 shares of the Company's common stock. This marked the Company's 17th stock repurchase plan. On March 16, 2020, the Company temporarily suspended stock repurchases and then on October 29, 2020 announced plans to resume purchases under the existing stock repurchase program. As of September 30, 2020, the Company had repurchased 207,829 shares under this plan at an average price of $15.71 per share. Cumulatively, since January 1998 the Company has repurchased 7,991,763 shares at an average price of $9.15 per share.

Item 7.  Management's Discussion and Analysis of Financial Condition and Results of Operations

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

General

Management's Discussion and Analysis of Financial Condition and Results of Operations is intended to assist in understanding the consolidated financial condition and results of operations of the Company.  The information contained in this section should be read in conjunction with the Consolidated Financial Statements and accompanying notes thereto included in Item 8 of this Annual Report on Form 10-K.

Overview

Timberland Bancorp, Inc., a Washington corporation, is the holding company for Timberland Bank.  The Bank opened for business in 1915 and serves consumers and businesses across Grays Harbor, Thurston, Pierce, King, Kitsap and Lewis counties, Washington with a full range of lending and deposit services through its 24 branches (including its main office in Hoquiam).  At September 30, 2020, the Company had total assets of $1.57 billion, net loans receivable of $1.01 billion, total deposits of $1.36 billion and total shareholders’ equity of $187.63 million.  The Company’s business activities generally are limited to passive investment activities and oversight of its investment in the Bank.  Accordingly, the information set forth in this report relates primarily to the Bank’s operations.

On October 1, 2018, the Company completed the South Sound Acquisition. The operating results for the years ended September 30, 2019 and 2020 include the operating results produced by the net assets acquired in the South Sound Acquisition. For additional information on the South Sound Acquisition, see Note 2 to the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

The Bank is a community-oriented bank which has traditionally offered a variety of savings products to its retail and business customers while concentrating its lending activities on real estate secured loans.  Lending activities have been focused primarily on the origination of loans secured by real estate, including residential construction loans, one- to four-family residential loans, multi-family loans and commercial real estate loans.  The Bank originates adjustable-rate residential mortgage loans, some of which do not qualify for sale in the secondary market.  The Bank also originates commercial business loans and other consumer loans.

The profitability of the Company’s operations depends primarily on its net interest income after provision for (recapture of) loan losses.  Net interest income is the difference between interest income, which is the income that the Company earns on interest-earning assets, which are primarily loans and investments, and interest expense, the amount the Company pays on its interest-bearing liabilities, which are primarily deposits and borrowings (as needed).  Net interest income is affected by changes in the volume and mix of interest-earning assets, the interest earned on those assets, the volume and mix of interest-bearing liabilities and the interest paid on those interest-bearing liabilities. Management attempts to maintain a net interest margin placing it within the top quartile of its Washington State peers. Because of the length of the COVID-19 pandemic and the efficacy of the extraordinary measures being put in place to address its economic consequences are unknown, including the 150 basis point reductions in the targeted federal funds rate (in March 2020), until the pandemic subsides, the Company expects its net interest income and net interest margin will be adversely affected.

The provision for (recapture of) loan losses is dependent on changes in the loan portfolio and management’s assessment of the collectability of the loan portfolio as well as prevailing economic and market conditions.  The allowance for loan losses reflects the amount that the Company believes is adequate to cover probable credit losses inherent in its loan portfolio. The Company recorded provisions for loan losses of $3.70 million for the year ended September 30, 2020 compared to none for the year ended September 30, 2019 due primarily to forecasted probable loan losses reflecting the potential future impact of the COVID-19 pandemic on the economy.

On March 24, 2020, Washington State Governor Jay Inslee signed a statewide order due to the COVID-19 pandemic requiring residents to stay-at-home unless involved in an essential activity. All business, except those that are considered essential, were also ordered to close. Although the stay-at-home order has been lifted and certain businesses were allowed to re-open, many restrictions remain in place. As an essential business, the Company took various steps to ensure the safety of customers and personnel including branch lobby closures. To ensure the safety of the Company's customers and employees, services are offered through drive up facilities and/or by appointment at some locations and other branch offices are now open

56

on a modified basis. Some of the Company's employees are working remotely or have flexible work schedules, and protective measures within the Company's offices have been established to help ensure the safety of those that employees who must work on-site.

The Company has worked with loan customers on loan deferral and forbearance plans. In response to requests from borrowers, the Company made payment deferral modifications (typically 90-day payment deferrals with interest continuing to accrue or scheduled to be paid monthly) on a number of loans. The majority of these borrowers had resumed making payments as of September 30, 2020 and only five loans totaling $5.87 million remained on deferral status as of that date. These modifications were not classified as TDRs at September 30, 2020 in accordance with guidance of the CARES Act and related regulatory guidance. The CARES Act also authorized the SBA to temporarily guarantee loans under a new loan program called the Paycheck Protection Program. As a qualified SBA lender, the Company was automatically authorized to originate PPP loans upon commencement of the program in April 2020 through its conclusion in August 2020. As of September 30, 2020, the Company had $126.82 million in PPP loans to new and existing customers who are small to midsize businesses as well as non-profit organizations, independent contractors, and partnerships as allowed under PPP guidance issued in April 2020.

Net income is also affected by non-interest income and non-interest expense.  For the year ended September 30, 2020, non-interest income consisted primarily of service charges on deposit accounts, gain on sales of loans, ATM and debit card interchange transaction fees, an increase in the cash surrender value of BOLI, servicing income on loans sold, escrow fee and other operating income.  Non-interest income is also increased by net recoveries on investment securities and reduced by net OTTI losses on investment securities, if any. Non-interest income is also decreased by by valuation allowances on servicing rights and increased by recoveries of valuation allowances on servicing rights, if any.  Non-interest expense consisted primarily of salaries and employee benefits, premises and equipment, advertising, ATM and debit card interchange transaction fees, postage and courier expenses, amortization of CDI, state and local taxes, professional fees, FDIC insurance premiums, loan administration and foreclosure expenses, data processing and telecommunication expenses, deposit operation expenses and other non-interest expenses. Non-interest expense in certain periods are reduced by gains on the sale of premises and equipment and by gains on the sale of OREO.  Non-interest income and non-interest expense are affected by the growth of the Company's operations and growth in the number and balances of loan and deposit accounts.

Results of operations may be affected significantly by general and local economic and competitive conditions, changes in market interest rates, governmental policies and actions of regulatory authorities.

Operating Strategy

The Company is a bank holding company which operates primarily through its subsidiary, the Bank. The Company's primary objective is to operate the Bank as a well capitalized, profitable, independent, community-oriented financial institution, serving customers in its primary market area of Grays Harbor, Pierce, Thurston, Kitsap, King and Lewis counties. The Company's strategy is to provide products and superior service to small businesses and individuals located in its primary market area.

The Company's goal is to deliver returns to shareholders by focusing on the origination of higher-yielding assets (in particular commercial real estate, construction, and commercial business loans), increasing core deposit balances, managing problem assets, efficiently managing expenses, and seeking expansion opportunities. The Company seeks to achieve these results by focusing on the following objectives:

Expand our presence within our existing market areas by capturing opportunities resulting from changes in the competitive environment. We currently conduct our business primarily in western Washington. We have a community bank strategy that emphasizes responsive and personalized service to our customers. As a result of the consolidation of banks in our market areas, we believe there is an opportunity for a community and customer focused bank to expand its customer base. By offering timely decision making, delivering appropriate banking products and services, and providing customer access to our senior managers we believe community banks, such as Timberland Bank, can distinguish themselves from larger banks operating in our market areas. We believe we have a significant opportunity to attract additional borrowers and depositors and expand our market presence and market share within our extensive branch footprint.

Portfolio diversification. In recent years, we have limited the origination of speculative construction loans and land development loans in favor of loans that possess credit profiles representing less risk to the Bank. We continue originating owner/builder and custom construction loans, multi-family loans, commercial business loans and commercial real estate loans which offer higher risk adjusted returns, shorter maturities and more sensitivity to interest rate fluctuations than fixed rate one-to four-family loans. We anticipate capturing more of each customer's banking relationship by cross selling our loan and deposit products and offering additional services to our customers.

57

Increase core deposits and other retail deposit products. We focus on establishing a total banking relationship with our customers with the intent of internally funding our loan portfolio. We anticipate that the continued focus on customer relationships will increase our level of core deposits. In addition to our retail branches, we maintain technology based products such as business cash management and a business remote deposit product that enable us to compete effectively with banks of all sizes.

Managing exposure to fluctuating interest rates. For many years, the majority of the loans the Bank has retained in its portfolio have generally possessed periodic interest rate adjustment features or have been relatively short term in nature. Loans originated for portfolio retention have generally included ARM loans, short-term construction loans, and to a lesser extent commercial business loans with interest rates tied to a market index such as the Prime Rate. Longer term fixed-rate mortgage loans have generally been originated for sale into the secondary market, although from time to time the Bank may retain a portion of its fixed-rate mortgage loan originations and extend the initial fixed rate period of its hybrid ARM commercial real estate loans for asset/liability purposes.

Continue generating revenues through mortgage banking operations. The substantial majority of the fixed-rate residential mortgage loans we originate are sold into the secondary market with servicing retained. This strategy produces gains on the sale of such loans and reduces the interest rate and credit risk associated with fixed-rate residential lending. We continue to originate custom construction and owner/builder construction loans for sale into the secondary market upon the completion of construction.

Maintaining strong asset quality. We believe that strong asset quality is a key to our long-term financial success. The percentage of non-performing loans to loans receivable, net was 0.28% and 0.34% at September 30, 2020 and 2019, respectively. The Company's percentage of non-performing assets to total assets at September 30, 2020 was 0.27% compared to 0.40% at September 30, 2019. Non-performing assets have decreased to $4.16 million at September 30, 2020 from $14.98 million at September 30, 2015. We continue to seek to reduce the level of non-performing assets through collections, write-downs, modifications and sales of OREO. We also take proactive steps to resolve our non-performing loans, including negotiating payment plans, forbearances, loan modifications and loan extensions and accepting short payoffs on delinquent loans when such actions have been deemed appropriate. We have also accepted short payoffs on delinquent loans, particularly when such payoffs result in a smaller loss to us than foreclosure. Although the Company plans to continue to place emphasis on certain lending products, such as commercial real estate loans, construction loans, and commercial business loans, the Company expects to continue to manage its credit exposures through the use of experienced bankers and an overall conservative approach to lending.

Critical Accounting Policies and Estimates

The Company has established various accounting policies that govern the application of GAAP in the preparation of the Company's Consolidated Financial Statements. The Company has identified six policies that as a result of judgments, estimates and assumptions inherent in those policies, are critical to an understanding of the Company's Consolidated Financial Statements. These policies relate to the methodology for the determination of the allowance for loan losses, the determination of any OTTI in the fair value of investment securities, the valuation of servicing rights, the valuation of OREO, the valuation of assets acquired and liabilities assumed in acquisitions and the valuation of goodwill for potential impairment. These policies and the judgments, estimates and assumptions are described in greater detail in the notes to the Consolidated Financial Statements contained in Item 8 of this Form 10-K. In particular, Note 1 to the Consolidated Financial Statements, “Summary of Significant Accounting Policies,” generally describes the Company's accounting policies. Management believes that the judgments, estimates and assumptions used in the preparation of the Company's Consolidated Financial Statements are appropriate given the factual circumstances at the time. However, given the sensitivity of the Company's Consolidated Financial Statements to these critical policies, the use of other judgments, estimates and assumptions could result in material differences in the Company's results of operations or financial condition.

Market Risk and Asset and Liability Management

General.  Market risk is the risk of loss from adverse changes in market prices and rates.  The Bank's market risk arises primarily from interest rate risk inherent in its lending, investment, deposit and borrowing activities.  The Bank, like other financial institutions, is subject to interest rate risk to the extent that its interest-earning assets reprice differently than its interest-bearing liabilities.  Management actively monitors and manages its interest rate risk exposure.  Although the Bank manages other risks, such as credit quality and liquidity risk, in the normal course of business management considers interest rate risk to be its most significant market risk that could potentially have the largest material effect on the Bank's financial condition and results of operations.  The Bank does not maintain a trading account for any class of financial instruments nor does it engage in hedging activities.  Furthermore, the Bank is not subject to foreign currency exchange rate risk or commodity price risk.

58

Qualitative Aspects of Market Risk.  The Bank's principal financial objective is to achieve long-term profitability while reducing its exposure to fluctuating market interest rates.  The Bank has sought to reduce the exposure of its earnings to changes in market interest rates by attempting to manage the difference between asset and liability maturities and interest rates.  The principal element in achieving this objective is to increase the interest rate sensitivity of the Bank's interest-earning assets by retaining in its portfolio, short-term loans and loans with interest rates subject to periodic adjustments.  The Bank relies on retail deposits as its primary source of funds.  As part of its interest rate risk management strategy, the Bank promotes transaction accounts and certificates of deposit with terms of up to five years.

The Bank has adopted a strategy that is designed to substantially match the interest rate sensitivity of assets relative to its liabilities.  The primary elements of this strategy involve originating ARM loans for its portfolio, maintaining residential construction loans as a portion of total net loans receivable because of their generally shorter terms and higher yields than other one- to four-family residential mortgage loans, matching asset and liability maturities, investing in short-term securities, and originating fixed-rate loans for retention or sale in the secondary market while retaining the related servicing rights.

Sharp increases or decreases in interest rates may adversely affect the Bank's earnings.  Management of the Bank monitors the Bank's interest rate sensitivity through the use of a model provided by NXTsoft Data Analytics, LLC (“NXTsoft”), a company that specializes in providing interest rate risk and balance sheet management services to the financial services industry. Based on a rate shock analysis prepared by NXTsoft based on data at September 30, 2020, an immediate increase in interest rates of 100 basis points would increase the Bank’s projected net interest income by approximately 7.7%, primarily because a larger portion of the Bank's interest rate sensitive assets than interest rate sensitive liabilities would reprice within a one year period.  Conversely, an immediate decrease in interest rates of 100 basis points would decrease the Bank's projected net interest income by approximately 2.4%. See “Quantitative Aspects of Market Risk” below for additional information.  Management has sought to sustain the match between asset and liability maturities and rates, while maintaining an acceptable interest rate spread.  Pursuant to this strategy, the Bank actively originates adjustable-rate loans for retention in its loan portfolio.  Fixed-rate mortgage loans with maturities greater than seven years generally are originated for the immediate or future resale in the secondary mortgage market.  Although the Bank has sought to originate ARM loans, the ability to originate such loans depends to a great extent on market interest rates and borrowers' preferences.  In lower interest rate environments, borrowers often prefer fixed-rate loans.

Consumer, commercial business and construction loans typically have shorter terms and higher yields than permanent residential mortgage loans, and accordingly reduce the Bank’s exposure to fluctuations in interest rates. At September 30, 2020, the consumer, commercial business and construction loan portfolios amounted to $35.65 million, $196.36 million and $219.50 million, or 3.1%, 17.3% and 19.4% of total loans receivable, respectively.

Quantitative Aspects of Market Risk.  The model provided for the Bank by NXTsoft estimates the changes in net portfolio value ("NPV") and net interest income in response to a range of assumed changes in market interest rates.  The model first estimates the level of the Bank's NPV (market value of assets, less market value of liabilities, plus or minus the market value of any off-balance sheet items) under the current rate environment.  In general, market values are estimated by discounting the estimated cash flows of each instrument by appropriate discount rates.  The model then recalculates the Bank's NPV under different interest rate scenarios.  The change in NPV under the different interest rate scenarios provides a measure of the Bank's exposure to interest rate risk.  The following table is provided by NXTsoft based on data at September 30, 2020:

Computations of prospective effects of hypothetical interest rate changes are based on numerous assumptions, including relative levels of market interest rates, loan repayments and deposit decay, and should not be relied upon as indicative of actual results.  Furthermore, the computations do not reflect any actions management may undertake in response to changes in interest rates.

In the event of a 100 basis point decrease in interest rates, the Bank would be expected to experience a 9.0% decrease in NPV and a 2.4% decrease in net interest income.  In the event of a 100 basis point increase in interest rates, an 8.3% increase in NPV and a 7.7% increase in net interest income would be expected.  Based upon the modeling described above, the Bank's asset and liability structure generally results in increases in net interest income and NPV in a rising interest rate scenario and decreases in net interest income and NPV in a declining interest rate scenario.

As with any method of measuring interest rate risk, certain shortcomings are inherent in the method of analysis presented in the foregoing table.  For example, although certain assets and liabilities may have similar maturities or periods to repricing, they may react in different degrees to changes in market interest rates.  Also, the interest rates on certain types of assets and liabilities may fluctuate in advance of changes in market interest rates, while interest rates on other types may lag behind changes in market rates.  Additionally, certain assets have features which restrict changes in interest rates on a short-term basis and over the life of the asset.  Further, in the event of a change in interest rates, expected rates of prepayments on loans and early withdrawals from certificates of deposit could possibly deviate significantly from those assumed in calculating the table.

Comparison of Financial Condition at September 30, 2020 and September 30, 2019

The Company's total assets increased by $318.85 million, or 25.6%, to $1.57 billion at September 30, 2020 from $1.25 billion at September 30, 2019.  The increase in assets was primarily due to increase in total cash and cash equivalents, net loans receivable, and investment securities. The increase in total assets was funded primarily by increases in total deposits and FHLB borrowings.

Net loans receivable increased by $127.21 million, or 14.3%, to $1.01 billion at September 30, 2020 from $886.66 million at September 30, 2019, primarily due to increases in commercial business (including $126.82 million of SBA PPP loans), commercial real estate, and multi-family loans. These increases were partially offset by decreases in one- to four-family mortgage and consumer loans.

Total deposits increased by $290.18 million, or 27.2%, to $1.36 billion at September 30, 2020 from $1.07 billion at September 30, 2019, primarily due to increases in non-interest bearing demand account balances, NOW checking account balances, savings account balances, and money market account balances.

Shareholders' equity increased by $16.56 million, or 9.7%, to $187.63 million at September 30, 2020 from $171.07 million at September 30, 2019.  The increase was primarily due to net income for the year ended September 30, 2020 of $24.27 million which was partially offset by $7.08 million in dividends paid to shareholders and $1.24 million in common stock repurchases.

A more detailed explanation of the changes in significant balance sheet categories follows:

Cash and Cash Equivalents: Cash and cash equivalents increased by $171.44 million, or 119.9%, to $314.45 million at September 30, 2020 from $143.02 million at September 30, 2019.  The increase was primarily a result of increases in total deposits, which exceeded the funds required for loan originations and purchases of investment securities.

CDs Held for Investment: CDs held for investment decreased by $12.80 million, or 16.3%, to $65.55 million at September 30, 2020 from $78.35 million at September 30, 2019. Funds received as CDs matured were invested into other interest-earning assets as interest rates on CDs decreased during the year.

Investment Securities and Investments in Equity Securities:  Investment securities and investments in equity securities increased by $32.18 million, or 59.0%, to $86.77 million at September 30, 2020 from $54.59 million at September 30, 2019.  The increase was primarily due to the purchase of additional agency mortgage-backed investment securities as the Company put a portion of its excess overnight liquidity into higher-earning investment securities during the year ended September 30, 2020. These increases were partially offset by maturities, prepayments and scheduled amortization of other investment securities. For additional details on investment securities, see "Item 1. Business - Investment Activities" and Note 4 to the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

60

FHLB Stock: FHLB stock increased by $485,000, or 33.8%, to $1.92 million at September 30, 2020 from $1.44 million at September 30, 2019, due to purchases required by the FHLB as a result of the increase in total assets and FHLB borrowings.

Other Investments: Other investments consist solely of the Company's investment in the Solomon Hess SBA Loan Fund LLC, which was unchanged at both September 30, 2020 and 2019. This investment is utilized to help satisfy compliance with the Company's Community Reinvestment Act ("CRA") investment test requirements.

Loans Held for Sale: Loans held for sale decreased to $4.51 million, or 25.7%, at September 30, 2020 from $6.07 million at September 30, 2019, primarily due to the timing and volume of mortgage banking loan sales. The Company sells longer-term fixed-rate residential loans and the guaranteed portion of SBA commercial business loans for asset-liability management purposes and to generate non-interest income.  The Company sold $167.24 million in loans during the year ended September 30, 2020 compared to $73.03 million for the year ended September 30, 2019. Sales of loans increased primarily due to increased refinance activity for one- to four-family loans due to the decrease in mortgage interest rates.

Loans Receivable, Net of Allowance for Loan Losses:  Net loans receivable increased by $127.21 million, or 14.3%, to $1.01 billion at September 30, 2020 from $886.66 million at September 30, 2019. The increase consisted of a $131.60 million increase in commercial business loans (including a $126.82 million increase in SBA PPP loans), a $34.46 million increase in commercial real estate loans, a $9.02 million increase in multi-family loans and smaller increases in several other categories. These increases were partially offset by a $14.08 million decrease in one- to four-family loans, an $8.85 million decrease in consumer loans and smaller decreases in several other categories.

Loan originations increased by $241.15 million, or 67.7%, to $597.19 million for the year ended September 30, 2020 from $356.04 million for the year ended September 30, 2019.  The increase in loan originations was primarily due to the funding of SBA PPP loans, increased loan demand for one- to four-family mortgage loan refinances, and the funding of several larger commercial business and commercial real estate loans. For additional information on loans, see "Item 1. Business - Lending Activities" and Note 5 to the Consolidated Financial Statements contained in "Item 8, Financial Statements and Supplementary Data."

Premises and Equipment, Net:  Premises and equipment increased by $205,000, or 0.9%, to $23.04 million at September 30, 2020 from $22.83 million at September 30, 2019.  The increase was primarily due to capitalized remodeling costs associated with the Company's new data center facility. This increase was partially offset by normal depreciation and the sale of land acquired in the South Sound Acquisition that had been held for future expansion. For additional information on premises and equipment, see "Item 2. Properties" and Note 6 to the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

OREO and Other Repossessed Assets:  OREO and other repossessed assets decreased by $633,000, or 37.6%, to $1.05 million at September 30, 2020 from $1.68 million at September 30, 2019.  The decrease was primarily due to the sales of $460,000 in OREO properties and OREO valuation write-downs of $173,000. At September 30, 2020, total OREO and other repossessed assets consisted of six land parcels totaling $1.05 million.  The largest OREO property at September 30, 2020 was an undeveloped land parcel located in Lewis County with a balance of $702,000.  For additional information on OREO and other repossessed assets, see "Item 1. Business - Lending Activities - Other Real Estate Owned and Other Repossessed Assets" and Note 7 to the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

Bank Owned Life Insurance ("BOLI"):  BOLI increased by $591,000, or 2.8%, to $21.60 million at September 30, 2020 from $21.01 million at September 30, 2019. The increase was due to net BOLI earnings, representing the increase in cash surrender value of the BOLI policies.

Goodwill:  The recorded amount of goodwill remained unchanged at $15.13 million at September 30, 2020 from September 30, 2019. The Company performed its annual review of goodwill during the quarter ended June 30, 2020 and determined that there was no impairment.  As of September 30, 2020, management believes that there had been no subsequent events or changes in circumstances that would indicate a potential impairment of goodwill. For additional information on goodwill, see Note 8 to the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

CDI: CDI decreased by $406,000, or 20.0% to $1.63 million at September 30, 2020 from $2.03 million at September 30, 2019 due to scheduled amortization. For additional information on CDI, see Note 8 to the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

61

Servicing Rights, Net:  Servicing rights increased by $687,000, or 28.5%, to $3.10 million at September 30, 2020 from $2.41 million at September 30, 2019, primarily due to additional capitalized Freddie Mac servicing rights for loans being sold with servicing retained, which was partially offset by amortization and valuation allowances. The principal amount of loans serviced for Freddie Mac and the SBA increased by $27.46 million, or 6.9%, to $426.58 million at September 30, 2020 from $399.12 million at September 30, 2019.  For additional information on servicing rights, see Note 9 to the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

Operating Lease Right-of-Use Assets: Operating lease right-of-use-assets increased to $2.59 million at September 30, 2020 as the Company adopted ASC 842 on October 1, 2019 and began recording operating lease right-of-use assets and operating lease liabilities on the balance sheet. The operating lease right-of-use assets at September 30, 2020 represented the present value of three operating leases on branch facilities. The Company adopted the provisions of ASC 842 utilizing the optional transition method and therefore prior periods have not been restated. For additional information on leases, see Note 10 to the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

Other Assets: Other assets decreased by $2.02 million, or 38.0%, to $3.30 million at September 30, 2020 from $5.32 million at September 30, 2019. The decrease was primarily due to decreases in miscellaneous receivables (including income tax receivables) and prepaid expenses.

Deposits: Deposits increased by $290.18 million, or 27.2%, to $1.36 billion at September 30, 2020 from $1.07 billion at September 30, 2019.  The increase consisted of a $145.42 million increase in non-interest bearing demand account balances, a $79.84 million increase in NOW checking account balances, a $55.36 million increase in savings account balances, and a $16.69 million increase in money market account balances. These increases were partially offset by a $7.13 million decrease in certificates of deposit account balances. The increase in deposits was primarily driven by proceeds from SBA PPP loans and government stimulus checks deposited directly into customer accounts, organic growth in customer relationships and reduced withdrawals from deposit accounts due to a change in spending habits as a result of COVID-19. For additional information on deposits, see "Item 1. Business - Deposit Activities and Other Sources of Funds" and Note 11 to the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

FHLB Borrowings: The Company has short- and long-term borrowing lines with the FHLB with total credit available on the lines equal to 45% of the Bank's total assets, limited by available collateral. FHLB borrowings increased to $10.00 million at September 30, 2020, as the Company borrowed funds consistent with its asset-liability objectives in March 2020 as long-term rates dropped to historic lows in response to the COVID-19 pandemic. At September 30, 2020, FHLB borrowings consisted of two $5.00 million borrowings, with scheduled maturities at March 2025 and March 2027, which bear interest at 1.19% and 1.11%, respectively. The Company did not have any FHLB borrowings at September 30, 2019. For additional information on FHLB borrowings, see Note 12 to the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data".

Operating Lease Liabilities: Operating lease liabilities increased to $2.63 million at September 30, 2020 as the Company adopted ASC 842 on October 1, 2019 and began recording operating lease liabilities and operating lease right-of-use assets on the balance sheet. The operating lease liability at September 30, 2020 represented the present value of three operating leases on branch facilities. The Company adopted the provisions of ASC 842 utilizing the optional transition method and therefore prior periods have not been restated. For additional information on leases, see Note 10 to the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

Other Liabilities and Accrued Expenses: Other liabilities and accrued expenses decreased by $526,000, or 6.7%, to $7.31 million at September 30, 2020 from $7.84 million at September 30, 2019. The decrease was primarily due to timing differences in the normal course of business and a reduction in deferred compensation payable.

Shareholders' Equity:  Total shareholders' equity increased by $16.56 million, or 9.7%, to $187.63 million at September 30, 2020 from $171.07 million at September 30, 2019.  The increase was primarily due to net income of $24.27 million for the year ended September 30, 2020, which was partially offset by the payment of $7.08 million in dividends to common shareholders and the repurchase of 56,601 shares of the Company's common stock for $1.24 million during the year ended September 30, 2020. For additional information on shareholders' equity, see the Consolidated Statements of Shareholders' Equity contained in "Item 8. Financial Statements and Supplementary Data."

Comparison of Operating Results for the Years Ended September 30, 2020 and 2019

Net income for the year ended September 30, 2020 increased by $249,000, or 1.0%, to $24.27 million from $24.02 million for the year ended September 30, 2019.  Net income per diluted common share increased by $0.04, or 1.4%, to $2.88

62

for the year ended September 30, 2020 from $2.84 for the year ended September 30, 2019. The increase in net income was primarily due to an increase in non-interest income and a decrease in non-interest expense. These increases to net income were partially offset by an increase in the provision for loan losses and a decrease in net interest income. The increase in non- interest income was primarily due to an increase in gain on sales of loans. The decrease in non-interest expense was primarily due to a decrease in data processing and telecommunication expenses. The increase in the provision for loan losses was primarily due to economic uncertainties associated with the COVID-19 pandemic.

A more detailed explanation of the income statement categories is presented below.

Net Interest Income:  Net interest income decreased by $278,000, or 0.5%, to $50.88 million for the year ended September 30, 2020 from $51.16 million for the year ended September 30, 2019.  The decrease in net interest income was primarily due to a decrease in the average yield on interest-earning assets, which was partially offset by an increase in the average balance of interest-earning assets.

Total interest and dividend income decreased by $142,000, or 0.3%, to $55.58 million for the year ended September 30, 2020 from $55.73 million for the year ended September 30, 2019, primarily due to a decrease in the average yield on interest-earning assets, which was partially offset by an increase in the average balance of interest-earning assets. The average yield on interest-earnings assets decreased to 4.26% for the year ended September 30, 2020 from 4.90% for the year ended September 30, 2019 as market rates decreased. Beginning in August 2019, the Federal Reserve reduced the targeted federal funds rate by 25 basis points three times in 2019 and during the quarter ended March 31, 2020 by 150 basis points in response to the COVID-19 pandemic, to a range of 0.00% to 0.25% at September 30, 2020. Partially offsetting the decrease in the average yield on interest-earning assets was an increase in the average balance of interest-earning assets. Average total interest-earning assets increased by $166.51 million, or 14.6%, to $1.30 billion for the year ended September 30, 2020 from $1.14 billion for the year ended September 30, 2019. Interest income on loans receivable and loans held for sale increased by $2.21 million, or 4.5%, to $51.34 million for the year ended September 30, 2020 from $49.13 million for the year ended September 30, 2019, primarily due to a $91.42 million increase in the average balance of loans receivable during the current year. This increase was partially offset by a decrease in the average yield on loans receivable to 5.29% for the year ended September 30, 2020 from 5.59% for the year ended September 30, 2019.

During the year ended September 30, 2020, the accretion of the purchase accounting fair value discount on loans acquired in the South Sound Acquisition increased interest income on loans by $597,000 compared to $645,000 for the year ended September 30, 2019. The accretion of the net fair value discount on acquired loans increased the average yield on loans by six basis points for the year ended September 30, 2020 and seven basis points for the year ended September 30, 2019. The incremental accretion and the impact on loan yield will change during any period based on the volume of prepayments, but it is expected to decrease over time as the balance of the net discount declines. The remaining net discount on these acquired loans was $790,000 at September 30, 2020. During the year ended September 30, 2020 a total of $911,000 in non-accrual interest, pre-payment penalties and late fees was collected compared to $372,000 for the year ended September 30, 2019.

Also impacting the average yield and average interest-earning asset balances during the year ended September 30, 2020 were SBA PPP loans originated. These PPP loans have a prescribed interest rate of 1.00% and are also subject to loan origination fees which are accreted into interest income over the life of each loan. For the year ended September 30, 2020, average PPP loans were $55.40 million and the Company recorded $556,000 in interest income and accreted $1.04 million in PPP loan origination fees into income. Interest income on investment securities increased by $315,000, or 24.9%, to $1.58 million for the year ended September 30, 2020 from $1.26 million for the year ended September 30, 2019 primarily due to an increase in the average balance of investment securities, which was partially offset by a decrease in the average yield on investment securities. Interest income on interest-bearing deposits in banks and CDs decreased by $2.64 million, or 51.0%, to $2.54 million for the year ended September 30, 2020 from $5.17 million for the year ended September 30, 2019, primarily due to an decrease in the average yield to 1.00% from 2.41% as market rates decreased. The decrease in the average yield was partially offset by an increase in the average balance of interest-bearing deposits in banks and CDs.

Total interest expense increased by $136,000, or 3.0%, to $4.70 million for the year ended September 30, 2020 from $4.57 million for the year ended September 30, 2019. The increase in interest expense was primarily due to a increases in the average balances of interest-bearing deposits and FHLB borrowings, which were partially offset by a decrease in the average cost of interest-bearing liabilities. Average interest-bearing deposits increased by $62.52 million, or 8.1%, to $829.91 million for the year ended September 30, 2020 from $767.39 million for the year ended September 30, 2019 and average FHLB borrowings increased to $5.69 million for the year ended September 30, 2020 from $0 for the year ended September 30, 2019. The average cost of interest-bearing liabilities decreased to 0.56% for the year ended September 30, 2020 from 0.59% for the year ended September 30, 2019 as market interest rates for deposits decreased.

63

As a result of these changes, the net interest margin decreased 60 basis points to 3.90% for the year ended September 30, 2020 from 4.50% for the year ended September 30, 2019.

Provision for Loan Losses: Provisions for loan losses totaled $3.70 million for the year ended September 30, 2020 compared to no provision for loan losses for the year ended September 30, 2019. The provision for loan for the current fiscal year was primarily due to the deteriorating economic conditions and probable loan losses driven by the impact of the COVID-19 pandemic on the U.S. and global economies. The Company had net recoveries of $24,000 for the year ended September 30, 2020 and net recoveries of $160,000 for the year ended September 30, 2019.  The net charge-offs (recoveries) to average outstanding loans ratio was 0.00% for the year ended September 30, 2020 and (0.02)% for the year ended September 30, 2019. The level of delinquent loans (loans 30 or more days past due) decreased by $177,000, or 4.5%, to $3.75 million at September 30, 2020 from $3.93 million at September 30, 2019 and the level of loans graded substandard decreased by $1.67 million, or 31.4%, to $3.65 million at September 30, 2020 from $5.32 million at September 30, 2019. Special mention loans increased by $3.32 million or 130.2%, to $5.86 million at September 30, 2020 from $2.55 million at September 30, 2019. Non-accrual loans decreased by $128,000, or 4.2%, to $2.91 million at September 30, 2020 from $3.03 million at September 30, 2019.

The Company has worked with loan customers impacted by the COVID-19 pandemic on loan deferral and forbearance plans. In response to requests from borrowers, the Company made payment deferral modifications (typically 90-day payment deferrals with interest continuing to accrue or scheduled to be paid monthly) on a number of loans during the year ended September 30, 2020. Most of these borrowers had resumed making payments during the year and only five loans totaling $5.87 million remained on deferral status as of September 30, 2020. These modifications were not classified as TDRs at September 30, 2020 in accordance with guidance of the CARES Act and related regulatory guidance.

The $126.82 million balance of SBA PPP loans was omitted from the Company's normal allowance for loan losses calculation at September 30, 2020 as these loans are fully guaranteed by the SBA and management expects that most PPP borrowers will seek full or partial forgiveness of their loan obligations from the SBA within a short time frame, which will in turn reimburse the Bank for the amount forgiven.

The Company has established a comprehensive methodology for determining the allowance for loan losses.  On a quarterly basis the Company performs an analysis that considers pertinent factors underlying the quality of the loan portfolio.  These factors include changes in the amount and composition of the loan portfolio, historic loss experience for various loan segments, changes in economic conditions, delinquency rates, a detailed analysis of impaired loans, and other factors to determine an appropriate level of allowance for loan losses.  Impaired loans are subject to an impairment analysis to determine an appropriate reserve amount to be allocated to each loan.  The aggregate principal impairment amount determined at September 30, 2020 was $41,000 compared to $172,000 at September 30, 2019.

In accordance with GAAP, loans acquired in the South Sound Acquisition were recorded at their estimated fair value, which resulted in a net discount to the loans' contractual amounts, of which a portion reflects a discount for possible credit losses. Credit discounts are included in the determination of fair value and as a result no allowance for loan losses is recorded for acquired loans at the acquisition date. The discount recorded on the acquired loans is not reflected in the allowance for loan losses or related allowance coverage ratios. The remaining fair value discount on loans acquired in the South Sound Acquisition was $790,000 at September 30, 2020. The Company believes this should be considered by investors when comparing the Company's allowance for loan losses to total loans in periods prior to the South Sound Acquisition.

Based on the comprehensive methodology, management believes the allowance for loan losses of $13.41 million at September 30, 2020 (1.31% of loans receivable and 461.8% of non-performing loans) was adequate to provide for probable losses based on an evaluation of known and inherent risks in the loan portfolio at that date.  While the Company believes it has established its existing allowance for loan losses in accordance with GAAP, there can be no assurance that bank regulators, in reviewing the Company's loan portfolio, will not request the Company to increase significantly its allowance for loan losses.  In addition, because future events affecting borrowers and collateral cannot be predicted with certainty, there can be no assurance that the existing allowance for loan losses is adequate or that substantial increases will not be necessary should the quality of any loans deteriorate.  Any material increase in the allowance for loan losses would adversely affect the Company's financial condition and results of operations.  For additional information, see "Item 1. Business - Lending Activities -- Allowance for Loan Losses."

Non-interest Income: Total non-interest income increased by $2.85 million, or 19.9%, to $17.19 million for the year ended September 30, 2020 from $14.34 million for the year ended September 30, 2019.  The increase was primarily due to a $4.23 million increase in gain on sales of loans, recoveries of $483,000 of previously charged off receivables acquired in the South Sound Acquisition (which are recorded in the "Other, net" non-interest category), and smaller increases in several other categories. These increases were partially offset by a $1.05 million decrease in BOLI net earnings, a $757,000 decrease in

64

service charges on deposits and smaller decreases in several other categories. The increase in gain on sales of loans was primarily due to an increase in the dollar amount of fixed rate one- to four-family loans originated and sold during the current year and an increase in the average pricing margin. The increase in mortgage banking volumes were largely due to increased refinance activity for single family homes due to lower mortgage interest rates. Net BOLI earnings were higher for the comparable period one year ago primarily due to a BOLI death benefit claim. The decrease in service charges on deposits was primarily due to a decrease in overdraft fee income.

Non-interest Expense:  Total non-interest expense decreased by $1.52 million, or 4.3%, to $34.06 million for the year ended September 30, 2020 from $35.58 million for the year ended September 30, 2019.  The decrease was primarily due to a $1.42 million decrease in data processing and telecommunications expense and smaller decreases in several other categories. Data processing related expenses were elevated for the year ended September 30, 2019 due to the Company's core operating system and ancillary technology systems conversions. The efficiency ratio for the year ended September 30, 2020 improved to 50.04% from 54.32% for the year ended September 30, 2019.

Provision for Income Taxes: The provision for income taxes increased by $137,000, or 2.3% to $6.04 million for the year ended September 30, 2020 from $5.90 million for the year ended September 30, 2019. The increase in the provision for income taxes was primarily due to higher income before income taxes. The Company's effective income tax rate was 19.9% for the year ended September 30, 2020 compared to 19.7% for the year ended September 30, 2019. Contributing to the lower effective income tax rate for the year ended September 30, 2019 was a higher percentage of tax-exempt income, primarily due to a BOLI death benefit claim. For additional information on income taxes, see Note 14 of the Consolidated Financial Statements contained in "Item 8. Financial Statements and Supplementary Data."

Average Balances, Interest and Average Yields/Cost

The earnings of the Company depend largely on the spread between the yield on interest-earning assets and the cost of interest-bearing liabilities, as well as the relative amount of the Company's interest-earning assets and interest- bearing liability portfolios.

65

The following table sets forth, for the periods indicated, information regarding average balances of assets and liabilities as well as the total dollar amounts of interest income from average interest-earning assets and interest expense on average interest-bearing liabilities and average yields and costs.  Such yields and costs for the periods indicated are derived by dividing income or expense by the average daily balance of assets or liabilities, respectively, for the periods presented.

Liquidity and Capital Resources

The Company's primary sources of funds are customer deposits, proceeds from principal and interest payments on loans, the sale of loans, maturing investment securities, maturing CDs held for investment and FHLB borrowings (if needed).  While the maturities and the scheduled amortization of loans are a predictable source of funds, deposit flows and mortgage prepayments are greatly influenced by general interest rates, economic conditions and competition.

The Bank must maintain an adequate level of liquidity to ensure the availability of sufficient funds to fund loan originations and deposit withdrawals, to satisfy other financial commitments and to take advantage of investment opportunities.  The Bank generally maintains sufficient cash and short-term investments to meet short-term liquidity needs.  At September 30, 2020, the Bank's regulatory liquidity ratio (net cash, and short-term and marketable assets, as a percentage of net deposits and short-term liabilities) was 29.1%.  At September 30, 2020, the Bank maintained an uncommitted credit facility with the FHLB that provided for immediately available borrowings up to an aggregate amount equal to 45% of total assets, limited by available collateral, under which $10.0 million was outstanding. The Bank had $364.09 million available for additional borrowings with the FHLB at September 30, 2020. The Bank maintains a short-term borrowing line with the FRB with total credit based on eligible collateral.  At September 30, 2020, the Bank had no outstanding balance on this borrowing line, under which $71.90 million was available for future borrowings. The Bank also maintains a $50.00 million overnight borrowing line with PCBB. At September 30, 2020, the Bank did not have an outstanding balance on this borrowing line.

67

Liquidity management is both a short and long-term responsibility of the Bank's management.  The Bank adjusts its investments in liquid assets based upon management's assessment of (i) expected loan demand, (ii) projected loan sales, (iii) expected deposit flows, and (iv) yields available on interest-bearing deposits.  Excess liquidity is invested generally in interest-bearing overnight deposits, CDs held for investment and short-term government and agency obligations.  If the Bank requires funds beyond its ability to generate them internally, it has additional borrowing capacity with the FHLB, the FRB and PCBB.

The Bank's primary investing activity is the origination of loans.  During the years ended September 30, 2020, 2019 and 2018, the Bank originated $597.19 million, $356.04 million and $329.59 million of loans, respectively.  At September 30, 2020, the Bank had loan commitments totaling $141.61 million and undisbursed construction loans in process totaling $100.56 million.  The Bank anticipates that it will have sufficient funds available to meet current loan commitments.  CDs that are scheduled to mature in less than one year from September 30, 2020 totaled $102.86 million.  Historically, the Bank has been able to retain a significant amount of its deposits as they mature.

The Bank’s liquidity is also affected by the volume of loans sold and loan principal payments.  During the years ended September 30, 2020, 2019 and 2018, the Bank sold $167.24 million, $73.03 million and $66.40 million in loans and loan participation interests, respectively.  During the years ended September 30, 2020, 2019 and 2018, the Bank received $287.04 million, $241.66 million and $235.61 million in principal repayments, respectively.

The Bank’s liquidity has been impacted by increases in deposit levels.  During the years ended September 30, 2020, 2019 and 2018, deposits increased by $290.18 million, $178.72 million and $51.61 million, respectively.

Cash and cash equivalents, CDs held for investment and investment securities increased to $465.79 million at September 30, 2020 from $275.00 million at September 30, 2019.

Timberland Bancorp is a separate legal entity from the Bank and must provide for its own liquidity and pay its own operating expenses. Sources of capital and liquidity for Timberland Bancorp include distributions from the Bank and the issuance of debt or equity securities. At September 30, 2020, Timberland Bancorp (on an unconsolidated basis) had liquid assets of $2.63 million.

Bank holding companies and federally-insured state-chartered banks are required to maintain minimum levels of regulatory capital.  At September 30, 2020, Timberland Bancorp and the Bank were in compliance with all applicable capital requirements.  For additional details see Note 18 to the Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” and “Item 1. Business - Regulation of the Bank - Capital Requirements.”

Contractual obligations.  The following table presents, as of September 30, 2020, the Company’s significant fixed and determinable contractual operating lease obligations by payment date. There were no other fixed determinable contractual obligations outstanding at September 30, 2020.

Effect of Inflation and Changing Prices

The consolidated financial statements and related financial data presented herein have been prepared in accordance with GAAP which require the measurement of financial position and operating results in terms of historical dollars, without considering the change in the relative purchasing power of money over time due to inflation.  The primary impact of inflation on the operation of the Company is reflected in increased operating costs.  Unlike most industrial companies, virtually all the assets and liabilities of a financial institution are monetary in nature.  As a result, interest rates generally have a more significant impact on a financial institution's performance than do general levels of inflation.  Interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of

Timberland Bancorp, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Timberland Bancorp, Inc. and Subsidiary (collectively, "the Company") as of September 30, 2020 and 2019, and the related consolidated statements of income, comprehensive income, shareholders' equity, and cash flows for each of the years in the three-year period ended September 30, 2020, and the related notes (collectively referred to as "the financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of September 30, 2020 and 2019, and the results of its operations and its cash flows for each of the years in the three-year period ended September 30, 2020, in conformity with accounting principles generally accepted in the United States of America (U.S.).

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company's auditor since 2010.

September 30, 2020 and 2019

Note 1 - 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.

On October 1, 2018, the Company completed the acquisition of South Sound Bank, a Washington-state chartered bank, headquartered in Olympia, Washington ("South Sound Acquisition"). The Company acquired 100% of the outstanding common stock of South Sound Bank, and South Sound Bank was merged into the Bank. The results of operations of the acquired assets and assumed liabilities have been included in the Company's consolidated financial statements as of and for the period since the acquisition date. See Note 2 for additional information on the South Sound Acquisition.

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 24 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 any OTTI in the fair value of investment securities, the valuation of servicing rights, the valuation of OREO, the valuation of assets acquired and liabilities assumed in acquisitions and the valuation of goodwill for potential impairment.

Certain prior year amounts have been reclassified to conform to the 2020 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.”

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. 

Interest-bearing deposits in banks as of September 30, 2020 and 2019 included deposits with the Federal Reserve Bank of San Francisco ("FRB") of $266,171,000 and $102,189,000, respectively.  The Company also maintains balances in correspondent bank accounts which, at times, may exceed the FDIC insurance limit of $250,000 per correspondent bank.  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.

September 30, 2020 and 2019

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 maturities of 12 to 60 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 

Investments in debt securities are classified upon acquisition as held to maturity or available for sale.  Investments in debt securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and reported at amortized cost.  Investments in debt securities classified as available for sale are reported 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 interest income 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 debt securities available for sale that are deemed to be other than temporary are recognized in earnings when identified.  The fair value of the debt security then becomes the new cost basis.  For individual debt 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 debt 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 debt 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 debt security’s cost basis and its fair value at the consolidated balance sheet date.  For individual debt 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.

Investments in Equity Securities

Investments in equity securities are stated at fair value. Prior to October 1, 2018, changes in the fair value of investments in equity securities were excluded from earnings and reported in other comprehensive income (loss), net of income tax effects. On October 1, 2018, the Company adopted ASU 2016-01 and reclassified its mutual funds as investments in equity securities. Beginning October 1, 2018, changes in the fair value of investments in equity securities are recorded in other non-interest income.

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 any 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, 2020 and 2019.

September 30, 2020 and 2019

Other Investments

The Bank invests in the Solomon Hess SBA Loan Fund LLC - a private investment fund - to help satisfy compliance with the Bank's Community Reinvestment Act ("CRA") investment test requirements. Shares in this fund are not publicly traded and therefore have no readily determinable fair value. The Bank's investment in the fund is recorded at cost. An investor can have its investment in the fund redeemed for the balance of its capital account at any quarter end with a 60 day notice to the fund.

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, net 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.

Acquired Loans

Purchased loans, including loans acquired in business combinations, are recorded at their estimated fair value at the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan losses is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either purchased credit-impaired ("PCI") or purchased non-credit-impaired. PCI loans reflect credit deterioration since origination such that it is probable at acquisition that the Company will be unable to collect all contractually required payments. The excess of the cash flows expected to be collected over a PCI loan's carrying value is considered to be the accretable yield and is recognized as interest income over the estimated life of the PCI loan using the effective yield method. The excess of the undiscounted contractual balances due over the cash flows expected to be collected is considered to be the nonaccretable difference. The nonaccretable difference represents the Company's estimate of the credit losses expected to occur and would be considered in determining the estimated

fair value of the loans as of the acquisition date. Subsequent to the acquisition date, any increases in expected cash flows over those expected at the purchase date in excess of fair value are adjusted through a change to the accretable yield on a prospective basis. Any subsequent decreases in expected cash flows attributable to credit deterioration are recognized by recording an allowance for loan losses. PCI loans were insignificant as of September 30, 2020 and 2019.

For purchased non-credit-impaired loans, the difference between the fair value and unpaid principal balance of the loan at the acquisition date is amortized or accreted to interest income over the life of the loans. Any subsequent deterioration in credit quality is recognized by recording an allowance for loan losses.

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 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. TDRs are considered impaired and are individually evaluated for impairment. TDRs 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. In March 2020, the Company announced loan modification programs to support and provide relief for its borrowers during the novel coronavirus of 2019 ("COVID-19") pandemic. The Company has followed the loan modification criteria within the Coronavirus Aid, Relief, and Economic Security Act of 2020 ("CARES Act"), which was signed into law on March 27, 2020 and interagency guidance from the federal banking agencies when determining if a borrower's modification is subject to a TDR classification. If it is determined that the modification does not meet the criteria under the CARES Act or interagency guidance to be excluded from TDR classification, the Company evaluates the loan modifications under its existing TDR framework. Loans subject to forbearance under the COVID-19 loan modification program are not reported as past due or placed on non-accrual status during the forbearance time period, and interest income continues to be recognized over the contractual life of the loans.

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 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-impaired loans 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.  When determining the appropriate historical loss and qualitative factors, management took into consideration the impact of the COVID-19 pandemic on such factors as the national and state unemployment rates and related trends, the amount of and timing of financial assistance provided by the government, consumer spending levels and trends, industries significantly impacted by the COVID-19 pandemic, and the Company's COVID-19 loan modification program. The appropriateness of the allowance for loan losses is estimated based upon these factors and trends identified by management at the time the consolidated financial statements are prepared.

A loan is considered impaired when it is probable that the Company 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 estimated net realizable value of the impaired loan is less than the recorded investment in the loan (including accrued interest

83

Notes to Consolidated Financial Statements

September 30, 2020 and 2019

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 and furniture and equipment - three to seven 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 undiscounted 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, 2020 or 2019 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. 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 values 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. Costs relating to development and improvement of the properties or assets are capitalized, while costs relating to holding the properties or assets are expensed.

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 in a business combination exceeds the estimated fair value of the net identified tangible and intangible assets acquired and liabilities assumed.  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. For purposes of goodwill impairment testing, the services offered through the Bank and its subsidiary are managed as one strategic unit and represent the Company's only reporting unit.

The annual goodwill impairment test begins with a qualitative assessment of whether it is "more likely than not" that the reporting unit's fair value is less than its carrying amount. If an entity concludes that it is not "more likely than not" that the fair value of a reporting unit is less than its carrying amount, it need not perform a two-step impairment test. If the Company's qualitative assessment concluded that it is "more likely than not" that the fair value of its reporting unit is less than its carrying amount, it must perform the two-step impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized, if any. The first step of the goodwill impairment test compares the estimated fair value of the reporting unit with its carrying amount, or the book value, including goodwill. If the estimated fair value of the reporting unit equals or exceeds its book value, goodwill is considered not impaired, and the second step of the impairment test is unnecessary.

The second step, if necessary, measures the amount of goodwill impairment loss to be recognized. The reporting unit must determine fair value for all assets and liabilities, excluding goodwill. The net of the assigned fair value of assets and liabilities is then compared to the book value of the reporting unit, and any excess book value becomes the implied fair value of goodwill. If the carrying amount of the goodwill exceeds the newly calculated implied fair value of goodwill, an impairment loss is recognized in the amount required to write-down the goodwill to the implied fair value.

Management's qualitative assessment takes into consideration macroeconomic conditions, industry and market considerations, cost or margin factors, financial performance and the share price of the Company's common stock. The Company performed its fiscal year 2020 goodwill impairment test during the quarter ended June 30, 2020 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, 2020 and the step one test concluded that the reporting unit's fair value was more than its recorded value and, therefore, step two of the analysis was not necessary. Accordingly, the recorded value of goodwill as of May 31, 2020 was not impaired.

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 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. Any change in these indicators 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, 2020, management believes that there were no events or changes in the circumstances since May 31, 2020 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. If adverse economic conditions or the recent decrease in the Company's stock price and market capitalization as a result of the COVID-19 pandemic were deemed to be other than temporary, it may significantly affect the fair value of the Company's goodwill and may trigger impairment charges. Any impairment charge could have a material adverse effect on the Company's results of operation and financial condition.

CDI

CDI represents the future economic benefit of the potential cost savings from acquiring core deposits as part of a business combination compared to the cost of alternative funding sources. CDI is amortized to non-interest expense using an accelerated method based on an estimated runoff of related deposits over a period of ten years. CDI is evaluated for impairment whenever events or changes in circumstances indicate that its carrying amount may not be recoverable, with any changes in estimated useful life accounted for prospectively over the revised remaining life.

Servicing Rights

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. Servicing rights are capitalized at estimated fair value when acquired through the origination of loans that are subsequently sold with the servicing rights retained. Servicing rights are amortized to servicing income on loans sold approximately in proportion to and over the period of estimated net servicing income.  The value of servicing rights 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 servicing rights must be stratified by one or more predominant risk characteristics of the underlying loans.  The Company stratifies its capitalized servicing rights 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 servicing rights 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 and various state income tax returns.  The Bank provides for income taxes separately and remits to (receives from) Timberland Bancorp amounts currently due (receivable).

Deferred 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, 2016.

ESOP

The Bank sponsors a leveraged ESOP; however, all ESOP debt was fully repaid during the year ended September 30, 2019. The debt of the ESOP was payable to Timberland Bancorp, was recorded as other borrowed funds of the Bank, and was eliminated in the consolidated financial statements. The shares of the Company's common stock pledged as collateral for the ESOP's debt were reported as unearned shares issued to the ESOP in the consolidated financial statements. As shares were released from collateral, compensation expense was recorded equal to the average market price of the shares for the period, and the shares became available for net income per common share calculations.  Dividends paid on unallocated shares reduced 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.  Stock option forfeitures are accounted for as they occur.

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 the Company's common stock during the period. Common stock equivalents arise from the assumed conversion of outstanding stock options.  Shares owned by the Bank’s ESOP that have not been allocated are not considered to be outstanding for the purpose of computing basic and diluted 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, 2020, 2019 and 2018 totaled $78,000, $69,000 and $94,000, respectively.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers, which created FASB Accounting Standards Codification ("ASC") Topic 606 ("ASC 606"). The core principle of ASC 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASC 606 was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company adopted ASC 606 on October 1, 2018 using the modified retrospective approach. Therefore, the comparative information has not been adjusted and continues to be reported under the superseded ASC 605. There was no cumulative effect adjustment as of October 1, 2018, and there were no material changes to the timing or amount of revenue recognized for the year ended September 30, 2019; however, additional disclosures were incorporated in the footnotes upon adoption. The majority of the Company's revenue is comprised of interest income from financial assets, which is explicitly excluded from the scope of ASC 606. The Company elected to apply the practical expedient pursuant to ASC 606 and therefore does not disclose information about remaining performance obligations that have an original expected term of one year or less and allows the Company to expense costs related to obtaining a contract as incurred when the amortization period would have been one year or less. See Note 24 for additional information.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 generally requires equity investments - except those accounted for under the equity method of accounting or those that result in consolidation of the investee - to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. ASU 2016-01 is intended to simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. ASU 2016-01 also eliminates certain disclosures related to the fair value of financial instruments and requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. ASU 2016-01 was effective for fiscal years beginning after December 15, 2017, including interim periods

within those fiscal years. The Company adopted ASU 2016-01 on October 1, 2018. As required by ASU 2016-01, on October 1, 2018 the Company recorded a one-time cumulative effect adjustment of $63,000 representing net unrealized losses on equity securities (mutual funds) between accumulated other comprehensive loss and retained earnings on the accompanying consolidated balance sheet. Additionally, the fair values of financial instruments for disclosure purposes were computed using an exit price notion and deposits with no stated maturity are no longer included in the fair value disclosures in Note 22.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which created FASB ASC Topic 842 ("ASC 842") and 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 ASC 842 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 generally on a 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. ASC 842 also changes disclosure requirements related to leasing activities and requires certain qualitative disclosures along with specific quantitative disclosures. ASC 842 also provides an optional transition method for adoption, under which an entity initially applies ASC 842 at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity's reporting for the comparative periods presented in the financial statements in which it adopts ASC 842 will continue to be in accordance with current GAAP. ASC 842 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early application of ASC 842 is permitted. The Company adopted the provisions of ASC 842 effective October 1, 2019 utilizing the optional transition method and will not restate comparative periods. The Company also elected the package of practical expedients permitted under ASC 842's transition guidance, which allows the Company to carryforward its historical lease classifications and its assessment as to whether a contract is or contains a lease. The Company also elected to not recognize lease assets and lease liabilities for leases with an initial term of 12 months or less. As a result of adopting ASC 842, ROU assets and operating lease liabilities increased by $2.89 million on October 1, 2019.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses, as amended by ASU 2018-19, ASU 2019-04 and ASU 2019-05. This ASU replaces the existing incurred losses methodology with a current expected 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 as a reduction of the carrying amount. ASU 2016-13 also changes the accounting for purchased credit-impaired debt securities and loans. ASU 2016-13 retains many of the current disclosure requirements in GAAP and expands certain disclosure requirements. ASU 2016-13 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Upon adoption, the Company expects a change in the processes and procedures to calculate the allowance for loan losses, including changes in the assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. In addition, the current policy for other-than-temporary impairment on investment securities available for sale will be replaced with an allowance approach. The Company is reviewing the requirements of ASU 2016-13 and has begun developing and implementing processes and procedures to ensure it is fully compliant with the amendments at the adoption date. At this time, the Company anticipates the allowance for loan losses will increase as a result of the implementation of this ASU; however, until its evaluation is complete, the magnitude of the increase will be unknown.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment. This ASU simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value of its assets and liabilities (including unrecognized assets and liabilities) at the impairment testing date following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by

which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax

deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. ASU 2017-04 is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2022.

The adoption ASU 2017-04 is not expected to a have a material impact on the Company's future consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This ASU shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. This ASU was effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018. The Company adopted ASU 2017-08 effective October 1, 2019 and it did not have a material impact on the Company's consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU was issued to provide clarity as to when to apply modification accounting when there is a change in the terms or conditions of a share-based payment award. According to the ASU, an entity should account for the effects of a modification unless the fair value, vesting conditions, and balance sheet classification of the award are the same after the modification as compared to the original award prior to modification. ASU 2017-09 was effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The Company adopted ASU 2017-09 effective October 1, 2018 and it did not have a material impact on the Company's consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This ASU was issued to expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. Previously, these awards were recorded at the fair value of consideration received or the fair value of the equity instruments issued and were measured at the earlier of the commitment date or the date performance was completed. The amendments in this ASU require nonemployee share-based payment awards to be measured at the grant-date fair value of the equity instrument. ASU 2018-07 was effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018. The Company adopted ASU 2018-07 effective October 1, 2019 and it did not have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements. The following disclosure requirements were removed from ASC Topic 820, Fair Value Measurement: (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; and (3) the valuation process for Level 3 fair value measurements. This ASU clarifies that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. This ASU adds the following disclosure requirements for Level 3 measurements: (1) changes in unrealized gains and losses for the period included in other comprehensive income for the recurring Level 3 fair value measurements held at the end of the reporting period, and (2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. ASU 2018-13 was effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted ASU 2018-13 effective October 1, 2020 and it is not expected to have a material impact on the Company's future consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40), Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this ASU broaden the scope of ASC Subtopic 350-40 to include costs incurred to implement a hosting arrangement that is a service contract. The amendments align the requirements for capitalizing implementation costs incurred

in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The costs are capitalized or expensed depending on the nature of the costs and the project stage during which they are incurred, consistent with the accounting for internal-use software costs. The amendments in this ASU result in consistent capitalization of implementation costs of a hosting arrangement that is a service contract and implementation costs incurred 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 in this ASU. ASU 2018-15 was effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted ASU 2018-15 effective October 1, 2020 and it is not expected to have a material impact on the Company's future consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidelines. ASU 2019-12 is effective for fiscal years beginning after December 15, 2021,

including interim periods within fiscal years. The adoption of ASU 2019-12 is not expected to have a material impact on the Company's future consolidated financial statements.

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU applies to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate ("LIBOR") or other rate references expected to be discontinued because of reference rate reform. The ASU permits an entity to make necessary modifications to eligible contracts or transactions without requiring contract remeasurement or reassessment of a previous accounting determination. This ASU is effective for all entities as of March 12, 2020 through December 31, 2022. The Company has not adopted ASU 2020-04 as of September 30, 2020. The adoption of ASU 2020-04 is not expected to have a material impact on the Company's future consolidated financial statements.

On March 22, 2020, federal banking regulators issued an interagency statement that included guidance on their approach for the accounting of loan modifications in light of the economic impact of the COVID-19 pandemic. The guidance interprets current accounting standards and indicates that a lender can conclude that a borrower is not experiencing financial difficulty if short-term modifications are made in response to COVID-19, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant related to the loans in which the borrower is less than 30 days past due on its contractual payments at the time a modification is implemented. The agencies confirmed in working with the staff of the FASB that short-term modification made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not troubled debt restructurings.

Note 2 - Business Combination

On October 1, 2018, the Company completed the South Sound Acquisition. The primary reason for the acquisition was to expand the Company's presence along Washington State's economically important I-5 corridor.

Pursuant to the terms of the merger agreement, South Sound Bank shareholders received 0.746 of a share of the Company's common stock and $5.68825 in cash per share of South Sound Bank common stock. The Company issued 904,826 shares of its common stock (valued at $28,267,000 based on the Company's closing stock price on September 30, 2018 of $31.24 per share) and paid $6,903,000 in cash in the transaction for total consideration paid of $35,170,000.

The South Sound Acquisition constitutes a business combination as defined by GAAP, which establishes principles and requirements for how the acquirer in a business combination recognizes and measures in its financial statements the identifiable assets acquired and liabilities assumed. The Company was considered the acquirer in this transaction. Accordingly, the estimated fair values of the acquired assets, including the identifiable intangible assets, and the assumed liabilities in the South Sound Acquisition were measured and recorded as of October 1, 2018. The excess of the total consideration paid over the fair value of the net assets acquired was allocated to goodwill. The South Sound Acquisition resulted in $9,481,000 of goodwill. The goodwill arising from this transaction consists largely of the synergies and expected economies of scale from combining the operations of the Company and South Sound Bank. This goodwill is not deductible for tax purposes.

In most instances, determining the estimated fair values of the acquired assets and assumed liabilities requires the Company to estimate cash flows expected to result from those assets and liabilities and to discount those cash flows at the appropriate rate of interest. Differences may arise between contractually required payments and the expected cash flows at the acquisition date due to items such as estimated credit losses, prepayments or early withdrawal, and other factors. One of the most significant of those determinations relates to the valuation of acquired loans. For such loans, the excess of cash flows expected at acquisition over the estimated fair value is recognized as interest income over the remaining lives of the loans. In accordance with GAAP, there was no carry-over of South Sound Bank's previously established allowance for loan losses.

The Company has evaluated the investment securities in the above tables and has determined that the decline in their fair value is temporary.  The unrealized losses are primarily due to changes in market interest rates and spreads in the market for mortgage-related products. The fair value of these securities is expected to recover as the securities approach their maturity dates and/or as the pricing spreads narrow on mortgage-related securities.  The Company has the ability and the intent to hold the investments until the fair value of these securities recovers.  Additional deterioration in market and economic conditions related to the COVID-19 pandemic may, however, have an adverse impact on credit quality in the future and result in OTTI charges.

The Company bifurcates OTTI into (1) amounts related to credit losses which are recognized through earnings and (2) amounts related to all other factors which are recognized as a component of other comprehensive income (loss).

To determine the component of the gross OTTI related to credit losses, the Company compared the amortized cost basis of the OTTI security to the present value of its revised expected cash flows, discounted using its pre-impairment yield. The revised expected cash flow estimates for individual securities are based primarily on an analysis of default rates, prepayment speeds and

Significant Concentrations of Credit Risk

Most of the Company’s lending activity is with customers located in the state of Washington and involves real estate.  At September 30, 2020, the Company had $934,351,000 (including $100,558,000 of undisbursed construction loans in process) in loans secured by real estate, which represented 82.4% of total loans receivable.  The real estate loan portfolio is primarily secured by one- to four-family properties, multi-family properties, land, and a variety of commercial real estate property types.  At September 30, 2020, there were no concentrations of real estate loans to a specific industry or secured by a specific collateral type that equaled or exceeded 20% of the Company’s total loan portfolio, other than loans secured by one-to four-

family properties.  The ultimate collectability of a substantial portion of the loan portfolio is susceptible to changes in economic and market conditions in the region and the impact of those changes on the real estate market.  The Company typically originates real estate loans with loan-to-value ratios of no greater than 90%.  Collateral and/or guarantees are required for all loans.

Loan Segment Risk Characteristics

The Company believes that its loan classes are the same as its loan segments.

One- To Four-Family Residential Lending:  The Company originates both fixed-rate and adjustable-rate loans secured by one- to four-family residences.  A portion of the fixed-rate one- to four-family loans are sold in the secondary market for asset/liability management purposes and to generate non-interest income.  The Company’s lending policies generally limit the maximum loan-to-value on one- to four-family loans to 90% of the lesser of the appraised value or the purchase price.  However, the Company usually obtains private mortgage insurance on the portion of the principal amount that exceeds 80% of the appraised value of the property.

Multi-Family Lending: The Company originates loans secured by multi-family dwelling units (more than four units).  Multi-family lending generally affords the Company an opportunity to receive interest at rates higher than those generally available from one- to four-family residential lending.  However, loans secured by multi-family properties usually are greater in amount, more difficult to evaluate and monitor and, therefore, involve a greater degree of risk than one- to four-family residential mortgage loans.  Because payments on loans secured by multi-family properties are often dependent on the successful operation and management of the properties, repayment of such loans may be affected by adverse conditions in the real estate market or economy.  The Company attempts to minimize these risks by scrutinizing the financial condition of the borrower, the quality of the collateral and the management of the property securing the loan.

Commercial Mortgage Lending: The Company originates commercial real estate loans secured by properties such as office buildings, retail/wholesale facilities, motels, restaurants, mini-storage facilities and other commercial properties.  Commercial real estate lending generally affords the Company an opportunity to receive interest at higher rates than those available from one- to four-family residential lending.  However, loans secured by such properties usually are greater in amount, more difficult to evaluate and monitor and, therefore, involve a greater degree of risk than one- to four-family residential mortgage loans. Because payments on loans secured by commercial properties are often dependent on the successful operation and management of the properties, repayment of these loans may be affected by adverse conditions in the real estate market or economy.  The Company attempts to mitigate these risks by generally limiting the maximum loan-to-value ratio to 80% and scrutinizing the financial condition of the borrower, the quality of the collateral and the management of the property securing the loan.

Construction Lending:  The Company currently originates the following types of construction loans: custom construction loans, owner/builder construction loans, speculative construction loans, commercial real estate construction loans, multi-family construction loans and land development loans. 

Construction lending affords the Company the opportunity to achieve higher interest rates and fees with shorter terms to maturity than does its single-family permanent mortgage lending.  Construction lending, however, is generally considered to involve a higher degree of risk than one- to four family residential lending because of the inherent difficulty in estimating both a property’s value at completion of the project and the estimated cost of the project.  The nature of these loans is such that they are generally more difficult to evaluate and monitor.  If the estimated cost of construction proves to be inaccurate, the Company may be required to advance funds beyond the amount originally committed to complete the project.  If the estimate of value upon completion proves to be inaccurate, the Company may be confronted with a project whose value is insufficient to assure full repayment, and the Company may incur a loss.  Projects may also be jeopardized by disagreements between borrowers and builders and by the failure of builders to pay subcontractors.  Loans to construct homes for which no purchaser has been

97

Notes to Consolidated Financial Statements

Timberland Bancorp, Inc. and Subsidiary

September 30, 2020 and 2019

identified carry more risk because the payoff for the loan depends on the builder’s ability to sell the property prior to the time that the construction loan is due.  The Company attempts to mitigate these risks by adhering to its underwriting policies, disbursement procedures and monitoring practices.

Construction Lending – Custom and Owner/Builder:  Custom construction and owner/builder construction loans are originated to home owners and are typically refinanced into permanent loans at the completion of construction.

Construction Lending – Speculative One- To Four-Family: Speculative one-to four-family construction loans are made to home builders and are termed “speculative” because the home builder does not have, at the time of the loan origination, a signed contract with a home buyer who has a commitment for permanent financing with the Company or another lender for the finished home.  The home buyer may be identified either during or after the construction period. 

Construction Lending – Commercial:  Commercial construction loans are originated to construct properties such as office buildings, hotels, retail rental space and mini-storage facilities.

Construction Lending – Multi-Family:  Multi-family construction loans are originated to construct apartment buildings and condominium projects.

Construction Lending - Land Development: Land development loans are originated to real estate developers for the purpose of developing residential subdivisions. The Company is currently originating land development loans on a limited basis.

Land Lending: The Company originates loans for the acquisition of land upon which the purchaser can then build or make improvements necessary to build or to sell as improved lots.  Loans secured by undeveloped land or improved lots involve greater risks than one- to four-family residential mortgage loans because these loans are more difficult to evaluate.  If the estimate of value proves to be inaccurate, in the event of default or foreclosure, the Company may be confronted with a property value which is insufficient to assure full repayment.  The Company attempts to minimize this risk by generally limiting the maximum loan-to-value ratio on land loans to 75%.

Consumer Lending – Home Equity and Second Mortgage:   The Company originates home equity lines of credit and second mortgage loans.  Home equity lines of credit and second mortgage loans have a greater credit risk than one- to four-family residential mortgage loans because they are secured by mortgages subordinated to the existing first mortgage on the property, which may or may not be held by the Company.  The Company attempts to mitigate these risks by adhering to its underwriting policies in evaluating the collateral and the credit-worthiness of the borrower.

Consumer Lending – Other: The Company originates other consumer loans, which include automobile loans, boat loans, motorcycle loans, recreational vehicle loans, savings account loans and unsecured loans.  Other consumer loans generally have shorter terms to maturity than mortgage loans.  Other consumer loans generally involve a greater degree of risk than do residential mortgage loans, particularly in the case of consumer loans that are unsecured or secured by rapidly depreciating assets such as automobiles.  In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation.  The Company attempts to mitigate these risks by adhering to its underwriting policies in evaluating the credit-worthiness of the borrower.

Commercial Business Lending:  The Company originates commercial business loans which, excluding SBA PPP loans, are generally secured by business equipment, accounts receivable, inventory or other property.  The Company also generally obtains personal guarantees from the business owners based on a review of personal financial statements.  Commercial business lending generally involves risks that are different from those associated with residential and commercial real estate lending.  Real estate lending is generally considered to be collateral based lending with loan amounts based on predetermined loan to collateral values, and liquidation of

the underlying real estate collateral is viewed as the primary source of repayment in the event of borrower default.  Although commercial business loans are often collateralized by equipment, inventory, accounts receivable or other business assets, the

liquidation of collateral in the event of a borrower default is often an insufficient source of repayment, because accounts receivable may be uncollectible and inventories and equipment may be obsolete or of limited use.  Accordingly, the repayment

of a commercial business loan depends primarily on the credit-worthiness of the borrower (and any guarantors), while the liquidation of collateral is a secondary and potentially insufficient source of repayment.  The Company attempts to mitigate

98

Notes to Consolidated Financial Statements

Timberland Bancorp, Inc. and Subsidiary

September 30, 2020 and 2019

these risks by adhering to its underwriting policies in evaluating the management of the business and the credit-worthiness of the borrowers and the guarantors.

SBA PPP: The CARES Act, which was signed into law on March 27, 2020, authorized the SBA to temporarily guarantee loans under a new loan program called PPP. As a qualified SBA lender, the Company was automatically authorized to originate PPP loans upon commencement of the program in April 2020 through the conclusion of the PPP on August 8, 2020. The SBA guarantees 100% of PPP loans made to eligible borrowers and the entire amount of the borrower's PPP loan, including any accrued interest, is eligible to be forgiven and repaid by the SBA. PPP loans have: (a) an interest rate of 1%, (b) a two-year loan term to maturity for loans approved by the SBA prior to June 5, 2020 and a five-year maturity for loans approved thereafter; and (c) principal and interest payments deferred for at least six months from the date of disbursement.

Credit Quality Indicators

The Company uses credit risk grades which reflect the Company’s assessment of a loan’s risk or loss potential.  The Company categorizes loans into risk grade categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors such as the estimated fair value of the collateral.  The Company uses the following definitions for credit risk ratings as part of the on-going monitoring of the credit quality of its loan portfolio:

Pass:  Pass loans are defined as those loans that meet acceptable quality underwriting standards.

Watch:  Watch loans are defined as those loans that still exhibit acceptable quality but have some concerns that justify greater attention.  If these concerns are not corrected, a potential for further adverse categorization exists.  These concerns could relate to a specific condition peculiar to the borrower, its industry segment or the general economic environment.

Special Mention: Special mention loans are defined as those loans deemed by management to have some potential weaknesses that deserve management’s close attention.  If left uncorrected, these potential weaknesses may result in the deterioration of the payment prospects of the loan.  

Substandard:  Substandard loans are defined as those loans that are inadequately protected by the current net worth and paying capacity of the obligor, or of the collateral pledged.  Loans classified as substandard have a well-defined weakness or weaknesses that jeopardize the repayment of the debt.  If the weakness or weaknesses are not corrected, there is the distinct possibility that some loss will be sustained.

Doubtful: Loans in this classification have the weaknesses of substandard loans with the additional characteristic that the weaknesses make the collection or liquidation in full on the basis of currently existing facts, conditions and values questionable, and there is a high possibility of loss. At September 30, 2020 and 2019, there were no loans classified as doubtful.

Loss:  Loans in this classification are considered uncollectible and of such little value that continuance as an asset is not warranted.  This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this loan even though partial recovery may be realized in the future. At September 30, 2020 and 2019, there were no loans classified as loss.

The CARES Act provided guidance around the modification of loans as a result of the COVID-19 pandemic, which outlined, among other criteria, that short-term modifications made on a good faith basis to borrowers who were current as defined under the CARES Act prior to any relief, are not TDRs. This includes short-term (e.g. six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. Borrowers are considered current under the CARES Act and related regulatory guidance if they are less than 30 days past due on their contractual payments at the time a modification program is implemented. In response to requests from borrowers, the Company made payment deferral modifications (typically 90-day payment deferrals with interest continuing to accrue or scheduled to be paid monthly) on a number of loans. The majority of these borrowers had resumed making payments as of September 30, 2020 and only five loans totaling $5,870,000 remained on deferral status under COVID-19 loan modification forbearance agreements as of that date. Loan modifications in accordance with the CARES Act and related regulatory guidance are still subject to an evaluation in regard to determining whether or not a loan is deemed to be impaired.

The following table details the COVID-19 loan modifications, still on deferral status, as of September 30, 2020 (dollars in thousands):

COVID-19 Loan Modifications

Total COVID-19 Modifications	5	$	5,870	100.0	%

The Company had $3,071,000 in TDRs included in impaired loans at September 30, 2020 and had no commitments to lend additional funds on these loans.  The Company had $3,269,000 in TDRs included in impaired loans at September 30, 2019 and had no commitments to lend additional funds on these loans. The allowance for loan losses allocated to TDRs at September 30, 2020 and 2019 was $3,000 and $56,000, respectively.

The following tables set forth information with respect to the Company’s TDRs by interest accrual status as of September 30, 2020 and 2019 (dollars in thousands):

Note 14 - Income Taxes

On December 22, 2017, the federal government enacted the Tax Cuts and Jobs Act (the "Tax Act"). The Tax Act significantly revised the future ongoing federal corporate income tax by, among other things, decreasing the federal corporate income tax rate to 21.0% from 35.0% effective January 1, 2018. As the Company has a September 30 fiscal year-end, the lower corporate income tax rate was phased in, resulting in a blended federal income tax rate of approximately 24.5% for the Company's fiscal year ended September 30, 2018, and 21.0% for subsequent fiscal years. In addition, the reduction of the corporate federal income tax rate required the Company to revalue its deferred tax assets and liabilities based on the lower federal income tax rate of 21.0%.

As a result of the Tax Act, during the year ended September 30, 2018, the Company recorded a one-time income tax expense of $548,000 in conjunction with remeasuring its net deferred tax assets. The impact of using the 24.5% blended federal income tax rate for the year ended September 30, 2018 versus a 35.0% rate reduced the provision for income taxes by approximately $2.21 million, which was partially offset by the $548,000 one-time net deferred tax asset remeasurement.

The components of the provision for income taxes for the years ended September 30, 2020, 2019 and 2018 were as follows (dollars in thousands):

	2020		2019		2018

No valuation allowance for deferred tax assets was recorded as of September 30, 2020 and 2019, as management believes that it is more likely than not that all of the deferred tax assets will be realized based on management's expectations of future taxable income.

Note 15 - Employee Stock Ownership and 401(k) Plan

The Timberland Bank Employee Stock Ownership and 401(k) Plan (“KSOP”) is comprised of two components, the ESOP and the 401(k) Plan.  The KSOP benefits employees with at least one year of service who are 18 years of age or older.  The Bank

may fund the ESOP with contributions of cash or stock, and may fund the 401(k) Plan with contributions of cash.  Employee vesting occurs over six years.

ESOP

In January 1998, the ESOP borrowed $7,930,000 from the Company to purchase 1,058,000 shares of common stock of the Company.  The loan was repaid primarily from the Bank’s contributions to the ESOP and was fully repaid by March 31, 2019. The interest rate on the loan was 8.5%. Interest expense on the ESOP debt was $9,000 and $53,000 for the years ended September 30, 2019 and 2018, respectively.

The amount of the Bank's annual contribution was discretionary, except that it must have been sufficient to enable the ESOP to service its debt.  All dividends received by the ESOP were used to pay debt service through March 31, 2019. The dividends received after March 31, 2019 have been paid directly to participants. Dividends of $176,000 and $291,000 were used to service the debt during the years ended September 30, 2019 and 2018, respectively.  As the Plan made each payment of principal and interest, an appropriate percentage of stock was released and allocated annually to eligible employee accounts, in accordance with applicable regulations. As of September 30, 2020, an aggregate of 642,302 ESOP shares, which were previously released for allocation to participants, had been distributed to participants.

Shares held by the ESOP as of September 30, 2020, 2019 and 2018 were classified as follows:

	2020	2019	2018
Unallocated shares	—	—	17,639
Shares released for allocation	415,698	425,281	451,644
Total ESOP shares	415,698	425,281	469,283

The approximate fair market value of the ESOP’s unallocated shares at September 30, 2018 was $551,000.  There was no compensation expense recognized for the ESOP for the year ended September 30, 2020. Compensation expense recognized for the ESOP for the years ended September 30, 2019 and 2018 was $318,000, and $823,000, respectively.

401(k) Plan

Eligible employees may contribute a portion of their wages to the 401(k) Plan up to the maximum established under the Internal Revenue Code.  Contributions by the Bank are at the discretion of the Board except for a safe harbor contribution of 3% of eligible employees' wages, which is mandatory according to the plan document.  Bank contributions totaled $908,000, $743,000 and $379,000 for the years ended September 30, 2020, 2019 and 2018, respectively.

Note 16 - Stock Compensation Plans

Shares issued may be purchased in the open market or may be issued from authorized and unissued shares. The exercise price of each option equals the fair market value of the Company’s common stock on the date of grant.  Generally, options and restricted stock vest in 20% annual installments on each of the five anniversaries from the date of the grant, and options generally have a maximum contractual term of ten years from the date of the grant.  At September 30, 2020, there were 25,556 shares of common stock available which may be awarded as options or restricted stock pursuant to future grants under the 2014 Equity Incentive Plan. At September 30, 2020 there were 299,500 shares of common stock available which may be awarded as options or restricted stock pursuant to future grants under the 2019 Equity Incentive Plan.

The aggregate intrinsic value of options exercised during the years ended September 30, 2020 and 2019 was $640,000 and $864,000, respectively.

The Company uses the Black-Scholes option pricing model to estimate the fair value of stock-based awards with the weighted average assumptions noted in the following table.  The risk-free interest rate is based on the rate of a U.S. Treasury security with a similar term as the expected life of the stock option at the particular grant date.  The expected life is based on historical data, vesting terms and estimated exercise dates. The expected dividend yield is based on the most recent quarterly dividend on an annualized basis in effect at the time the options were granted, adjusted, if appropriate, for management's expectations regarding future dividends.  The expected volatility is based on historical volatility of the Company’s stock price.  There were 45,950 options granted during the year ended September 30, 2018 with an aggregate grant date fair value of $206,000. There were 46,840 options granted during the year ended September 30, 2019 with an aggregate grant date fair value of $240,000. There were 69,150 options granted during the year ended September 30, 2020 with an aggregate grant date fair value of $187,000.

The weighted average assumptions for options granted during the years ended September 30, 2020, 2019 and 2018 were as follows:

	2020			2019			2018
Expected volatility	33		%	29		%	17		%
Expected life (in years)	5			5			5
Expected dividend yield	5.36		%	3.28		%	2.61		%
Risk free interest rate	0.28		%	1.53		%	2.97		%
Grant date fair value per share	$	2.70		$	5.12		$	4.48

There were 58,548 options that vested during the year ended September 30, 2020 with a total fair value of $176,000. There were 77,540 options that vested during the year ended September 30, 2019 with a total fair value of $203,000. There were 76,450 options that vested during the year ended September 30, 2018 with a total fair value of $181,000.

At September 30, 2020, there were 159,192 unvested options with an aggregate grant date fair value of $571,000, all of which the Company assumes will vest.  The unvested options had an aggregate intrinsic value of $99,000 at September 30, 2020.  At September 30, 2019, there were 160,750 unvested options with an aggregate grant date fair value of $605,000.

As of September 30, 2020, unrecognized compensation cost related to non-vested stock options was $595,000, which is expected to be recognized over a weighted average period of 2.36 years.

Note 17 - Commitments and Contingencies

In the normal course of business the Company is party to financial instruments with off-balance-sheet risk to meet the financing needs of its customers.  These financial instruments include commitments to extend credit.  These instruments involve, to varying degrees, elements of credit risk not recognized in the consolidated balance sheets. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments.  The Bank uses the same credit policies in making commitments as it does for on-balance-sheet instruments.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract.  Since commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.  The Company evaluates each customer’s credit-worthiness on a case-by-case basis.  The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party.  However, such loan to value ratios will subsequently change, based on increases and decreases in the supporting collateral values.  Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate, land and income-producing commercial properties.

A summary of the Company’s commitments at September 30, 2020 and 2019 is as follows (dollars in thousands):

	2020		2019
Undisbursed portion of construction loans in process (see Note 5)	$	100,558	$	92,226
Undisbursed lines of credit	103,030		80,184
Commitments to extend credit	38,581		16,578

The Company maintains a separate reserve for losses related to unfunded loan commitments.  Management estimates the amount of probable losses related to unfunded loan commitments by applying the loss factors used in the allowance for loan loss methodology to an estimate of the expected amount of funding and applies this adjusted factor to the unused portion of unfunded loan commitments.  The reserve for unfunded loan commitments totaled $384,000 and $241,000 at September 30, 2020 and 2019, respectively.  These amounts are included in other liabilities and accrued expenses in the accompanying

consolidated balance sheets.  Increases (decreases) in the reserve for unfunded loan commitments are recorded in non-interest expense in the accompanying consolidated statements of income.

The Bank has an employee severance compensation plan which expires in 2027 and which provides severance pay benefits to eligible employees in the event of a change in control of Timberland Bancorp or the Bank (as defined in the plan).  In general, all employees with two or more years of service will be eligible to participate in the plan.  Under the plan, in the event of a change in control of Timberland Bancorp or the Bank, eligible employees who are terminated or who terminate employment (but only upon the occurrence of events specified in the plan) within 12 months of the effective date of a change in control would be entitled to a payment based on years of service or officer rank with the Bank.  The maximum payment for any eligible employee would be equal to 18 months of the employee’s current compensation.

The Company has employment agreements with the Chief Executive Officer and the Chief Financial Officer which provide for a severance payment and other benefits if the officers are involuntarily terminated following a change in control of the Company or the Bank. The maximum value of the severance benefits under the employment agreements is 2.99 times the officer's average annual compensation during the five-year period prior to the effective date of the change in control.

Because of the nature of its activities, the Company is subject to various pending and threatened legal actions which arise in the ordinary course of business.  In the opinion of management, liabilities arising from these claims, if any, will not have a material effect on the consolidated financial position of the Company.

Note 18 - Regulatory Matters

The Bank, as a state-chartered, federally insured savings bank, is subject to the capital requirements established by the FDIC. Under the FDIC's capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank's assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by bank regulators that, if undertaken, could have a direct material effect on the Company's consolidated financial statements.

The minimum requirements are a common equity Tier 1 ("CET1") capital ratio of 4.5%, a Tier 1 capital ratio of 6.0%, a total capital ratio of 8.0% and a leverage ratio of 4.0%. In addition to the minimum regulatory capital ratios, the Bank is required to maintain a capital conservation buffer consisting of additional CET1 capital greater than 2.5% of risk-weighted assets above the required minimum levels in order to avoid limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses based on percentages of retained income that could be utilized for such actions. At September 30, 2020, the Bank's CET1 capital exceeded the required capital conservation buffer.

At September 30, 2020 and 2019, the Bank exceeded all regulatory capital requirements. The Bank was categorized as "well capitalized" at September 30, 2020 and 2019 under the regulations of the FDIC. The following tables compare the Bank’s actual capital amounts at September 30, 2020 and 2019 to its minimum regulatory capital requirements and "Well Capitalized" regulatory capital at those dates (dollars in thousands):

Timberland Bancorp is a bank holding company registered with the Federal Reserve. Bank holding companies are subject to capital adequacy requirements of the Federal Reserve under the Bank Holding Company Act of 1956, as amended, and the regulations of the Federal Reserve. For a bank holding company with less than $3.0 billion in assets, the capital guidelines apply on a bank only basis, and the Federal Reserve expects the holding company's subsidiary bank to be well capitalized under the prompt corrective action regulations. If Timberland Bancorp were subject to regulatory guidelines for bank holding companies with $3.0 billion or more in assets at September 30, 2020, Timberland Bancorp would have exceeded all regulatory requirements.

The following table presents the regulatory capital ratios for Timberland Bancorp at September 30, 2020 and 2019 assuming Timberland Bancorp was subject to regulatory guidelines for bank holding companies with $3.0 billion or more in assets (dollars in thousands):

Note 22 - Fair Value Measurements

Fair value is defined under GAAP as the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. GAAP requires that valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. GAAP also establishes a fair value hierarchy which prioritizes the valuation inputs into three broad levels. Based on the underlying inputs, each fair value measurement in its entirety is reported in one of three levels. These levels are:

Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2: Significant observable inputs other than quoted prices included within Level 1, such as quoted prices for similar (as opposed to identical) assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted prices that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs that reflect a company’s own assumptions about the assumptions market participants would use in pricing an asset or liability based on the best information available in the circumstances.

The Company's assets measured at fair value on a recurring basis consist of investment securities available for sale and investments in equity securities. The estimated fair values of MBS are based upon market prices of similar securities or observable inputs (Level 2). The estimated fair values of mutual funds are based upon quoted market prices (Level 1).

The Company had no liabilities measured at fair value on a recurring basis at September 30, 2020 and 2019. The Company's assets measured at estimated fair value on a recurring basis at September 30, 2020 and 2019 are as follows (dollars in thousands):

Total	$	958	$	22,532	$	—	$	23,490

There were no transfers among Level 1, Level 2 and Level 3 during the years ended September 30, 2020 and 2019.

The Company may be required, from time to time, to measure certain assets and liabilities at fair value on a non-recurring basis in accordance with GAAP.  These include assets that are measured at the lower of cost or market value that were recognized at fair value below cost at the end of the period.

The Company uses the following methods and significant assumptions to estimate fair value on a non-recurring basis:

Impaired Loans: The estimated fair value of impaired loans is calculated using the collateral value method or on a discounted cash flow basis. The specific reserve for collateral dependent impaired loans is based on the estimated fair value of the collateral less estimated costs to sell, if applicable.  In some cases, adjustments are made to the appraised values due to various factors including age of the appraisal, age of comparables included in the appraisal and known

123

Notes to Consolidated Financial Statements

September 30, 2020 and 2019

changes in the market and in the collateral. Such adjustments may be significant and typically result in a Level 3 classification of the inputs for determining fair value. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly.

Investment Securities Held to Maturity: The estimated fair value of investment securities held to maturity is based upon the assumptions market participants would use in pricing the investment security.  Such assumptions include quoted market prices (Level 1), market prices of similar securities or observable inputs (Level 2) and unobservable inputs such as dealer quotes, discounted cash flows or similar techniques (Level 3).

OREO and Other Repossessed Assets, net:  OREO and other repossessed assets are recorded at estimated fair value less estimated costs to sell.  Estimated fair value is generally determined by management based on a number of factors, including third-party appraisals of estimated fair value in an orderly sale.  Estimated costs to sell are based on standard market factors.  The valuation of OREO and other repossessed assets is subject to significant external and internal judgment (Level 3).

The following table summarizes the balances of assets measured at estimated fair value on a non-recurring basis at September 30, 2020 (dollars in thousands):

GAAP requires disclosure of estimated fair values for financial instruments.  Such estimates are subjective in nature, and significant judgment is required regarding the risk characteristics of various financial instruments at a discrete point in time.  Therefore, such estimates could vary significantly if assumptions regarding uncertain factors were to change.  In addition, as the Company normally intends to hold the majority of its financial instruments until maturity, it does not expect to realize many of the estimated amounts disclosed.  The disclosures also do not include estimated fair value amounts for certain items which are not defined as financial instruments but which may have significant value.  The Company does not believe that it would be practicable to estimate a fair value for these types of items as of September 30, 2020 and 2019.  Because GAAP excludes certain items from fair value disclosure requirements, any aggregation of the fair value amounts presented would not represent the underlying value of the Company. Additionally, in accordance with ASU 2016-01, which the Company adopted on October 1, 2018 on a prospective basis, the Company uses the exit price notion in calculating the fair values of financial instruments not measured at fair value on a recurring basis.

The Company assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations.  As a result, the estimated fair value of the Company’s financial instruments will change when interest rate levels change, and that change may either be favorable or unfavorable to the Company.  Management attempts to match maturities of assets and liabilities to the extent believed necessary to appropriately manage interest rate risk.  However, borrowers with fixed interest rate obligations are less likely to prepay in a rising interest rate environment and more likely to prepay in a falling

interest rate environment.  Conversely, depositors who are receiving fixed interest rates are more likely to withdraw funds before maturity in a rising interest rate environment and less likely to do so in a falling interest rate environment.  Management monitors interest rates and maturities of assets and liabilities, and attempts to manage interest rate risk by adjusting terms of new loans and deposits and by investing in securities with terms that mitigate the Company’s overall interest rate risk.

Notes to Consolidated Financial Statements

Timberland Bancorp, Inc. and Subsidiary

September 30, 2020 and 2019

Note 24 - Revenue from Contracts with Customers

In accordance with ASC 606, revenues are recognized when control of promised goods or services is transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services that are promised within each contract and identifies those that contain performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

ASC 606 applies to all contracts with customers to provide goods or services in the ordinary course of business, except for contracts that are specifically excluded from its scope. The majority of the Company's revenues are composed of interest income, deferred loan fee accretion, premium/discount accretion, gains on sales of loans and investments, BOLI net earnings, servicing income on loans sold and other loan fee income, which are not in the scope of ASC 606. Revenue reported as service charges on deposits, ATM and debit card interchange transaction fees, merchant services fees, non-deposit investment fees and escrow fees are within the scope of ASC 606. All of the Company's revenue from contracts with customers in the scope of ASC 606 is recognized in non-interest income with the exception of gains on sale of OREO and gains on sales/disposition of premises and equipment, which are included in non-interest expense. For the year ended September 30, 2020, the Company recognized $4,147,000 in services charges on deposits, $4,378,000 in ATM and debit card interchange fees, $273,000 in escrow fees and $22,000 in fee income from non-deposit investment sales, all considered within the scope of ASC 606. For the year ended September 30, 2019, the Company recognized $4,904,000 in service charges on deposits, $4,036,000 in ATM and debit card interchange fees, $197,000 in escrow fees and $46,000 in fee income from non-deposit investment sales, all considered within the scope of ASC 606.

Descriptions of the Company's revenue-generating activities that are within the scope of ASC 606 are as follows:

•Service Charges on Deposits: The Company earns fees from its deposit customers from a variety of deposit products and services. Non-transaction based fees such as account maintenance fees and monthly statement fees are considered to be provided to the customer under a day-to-day contract with ongoing renewals. Revenue for these non-transaction fees are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Transaction-based fees such as non-sufficient fund charges, stop payment charges and wire fees are recognized at the time the transaction is executed as the contract duration does not extend beyond the service performed.

•ATM and Debit Card Interchange Transaction Fees: The Company earns fees from cardholder transactions conducted through third party payment network providers which consist of interchange fees earned from the payment networks as a debit card issuer. These fees are recognized when the transaction occurs, but may settle on a daily or monthly basis.

•Escrow Fees: The Company earns fees from real estate escrow contracts with customers. The Company receives and disburses money and/or property per the customer's contract. Fees are recognized when the escrow contract closes.

•Fee income from Non-Deposit Investment Sales: The Company earns fees from contracts with customers for investment activities. Revenues are generally recognized on a monthly basis and are generally based on a percentage of the customer's assets under management or based on investment solutions that are implemented for the customer.

Item 9.  Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A.  Controls and Procedures

(a)           Evaluation of Disclosure Controls and Procedures: An evaluation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934 (the “Exchange Act”)) was carried out under the supervision and with the participation of the Company’s Chief Executive Officer, Chief Financial Officer and several other members of the Company’s senior management as of the end of the period covered by this annual report.  The Company’s Chief Executive Officer and Chief Financial Officer concluded that as of September 30, 2020 the Company’s disclosure controls and procedures were effective in ensuring that the information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is (i) accumulated and communicated to the Company’s management (including the Chief Executive Officer and Chief Financial Officer) in a timely manner, and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

(b)           Changes in Internal Controls:  There have been no changes in our internal control over financial reporting (as defined in 13a-15(f) of the Exchange Act) that occurred during the quarter ended September 30, 2020, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.  The Company continued, however, to implement suggestions from its internal auditor and independent auditor on ways to strengthen existing controls.  The Company does not expect that its disclosure controls and procedures and internal controls over financial reporting will prevent all errors and fraud.  A control procedure, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control procedure are met.  Because of the inherent limitations in all control procedures, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected.  These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns in controls or procedures can occur because of simple error or mistake.  Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control.  The design of any control procedure is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate.  Because of the inherent limitations in a cost-effective control procedure, misstatements due to error or fraud may occur and not be detected.

Management’s Report on Internal Control Over Financial Reporting

Management of Timberland Bancorp, Inc. (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13(a)-15(f) of the Securities Exchange Act of 1934. The Company's internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

To comply with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, the Company designed and implemented a structured and comprehensive assessment process to evaluate its internal control over financial reporting across the enterprise. The assessment of the effectiveness of the Company's internal control over financial reporting was based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

The Company's internal control over financial reporting includes policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company's assets that could have a material effect on the financial statements.

A control procedure, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Also, because of the inherent limitations in all control procedures, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. Additionally, in designing disclosure controls and procedures, our management was required to apply its

129

judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure controls and procedures is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. As a result of these inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Furthermore, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Based on its assessment, management has concluded that the Company's internal control over financial reporting was effective as of September 30, 2020.

The management of the Company has assessed the Company's compliance with the Federal laws and regulations pertaining to insider loans and the Federal and, if applicable, State laws and regulations pertaining to dividend restrictions during the fiscal year that ended on September 30, 2020. Management has concluded that the Company complied with the Federal laws and regulations pertaining to insider loans and the Federal and, if applicable, State laws and regulations.

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.

On October 1, 2018, the Company completed the acquisition of South Sound Bank, a Washington-state chartered bank, headquartered in Olympia, Washington ("South Sound Acquisition"). The Company acquired 100% of the outstanding common stock of South Sound Bank, and South Sound Bank was merged into the Bank. The results of operations of the acquired assets and assumed liabilities have been included in the Company's consolidated financial statements as of and for the period since the acquisition date. See Note 2 for additional information on the South Sound Acquisition.

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 24 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 any OTTI in the fair value of investment securities, the valuation of servicing rights, the valuation of OREO, the valuation of assets acquired and liabilities assumed in acquisitions and the valuation of goodwill for potential impairment.

Certain prior year amounts have been reclassified to conform to the 2020 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.”

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. 

Interest-bearing deposits in banks as of September 30, 2020 and 2019 included deposits with the Federal Reserve Bank of San Francisco ("FRB") of $266,171,000 and $102,189,000, respectively.  The Company also maintains balances in correspondent bank accounts which, at times, may exceed the FDIC insurance limit of $250,000 per correspondent bank.  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 maturities of 12 to 60 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 

Investments in debt securities are classified upon acquisition as held to maturity or available for sale.  Investments in debt securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and reported at amortized cost.  Investments in debt securities classified as available for sale are reported 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 interest income 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 debt securities available for sale that are deemed to be other than temporary are recognized in earnings when identified.  The fair value of the debt security then becomes the new cost basis.  For individual debt 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 debt 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 debt 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 debt security’s cost basis and its fair value at the consolidated balance sheet date.  For individual debt 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.

Investments in Equity Securities

Investments in equity securities are stated at fair value. Prior to October 1, 2018, changes in the fair value of investments in equity securities were excluded from earnings and reported in other comprehensive income (loss), net of income tax effects. On October 1, 2018, the Company adopted ASU 2016-01 and reclassified its mutual funds as investments in equity securities. Beginning October 1, 2018, changes in the fair value of investments in equity securities are recorded in other non-interest income.

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 any 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, 2020 and 2019.

Other Investments

The Bank invests in the Solomon Hess SBA Loan Fund LLC - a private investment fund - to help satisfy compliance with the Bank's Community Reinvestment Act ("CRA") investment test requirements. Shares in this fund are not publicly traded and therefore have no readily determinable fair value. The Bank's investment in the fund is recorded at cost. An investor can have its investment in the fund redeemed for the balance of its capital account at any quarter end with a 60 day notice to the fund.

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, net 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.

Acquired Loans

Purchased loans, including loans acquired in business combinations, are recorded at their estimated fair value at the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan losses is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either purchased credit-impaired ("PCI") or purchased non-credit-impaired. PCI loans reflect credit deterioration since origination such that it is probable at acquisition that the Company will be unable to collect all contractually required payments. The excess of the cash flows expected to be collected over a PCI loan's carrying value is considered to be the accretable yield and is recognized as interest income over the estimated life of the PCI loan using the effective yield method. The excess of the undiscounted contractual balances due over the cash flows expected to be collected is considered to be the nonaccretable difference. The nonaccretable difference represents the Company's estimate of the credit losses expected to occur and would be considered in determining the estimated

fair value of the loans as of the acquisition date. Subsequent to the acquisition date, any increases in expected cash flows over those expected at the purchase date in excess of fair value are adjusted through a change to the accretable yield on a prospective basis. Any subsequent decreases in expected cash flows attributable to credit deterioration are recognized by recording an allowance for loan losses. PCI loans were insignificant as of September 30, 2020 and 2019.

For purchased non-credit-impaired loans, the difference between the fair value and unpaid principal balance of the loan at the acquisition date is amortized or accreted to interest income over the life of the loans. Any subsequent deterioration in credit quality is recognized by recording an allowance for loan losses.

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 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. TDRs are considered impaired and are individually evaluated for impairment. TDRs 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. In March 2020, the Company announced loan modification programs to support and provide relief for its borrowers during the novel coronavirus of 2019 ("COVID-19") pandemic. The Company has followed the loan modification criteria within the Coronavirus Aid, Relief, and Economic Security Act of 2020 ("CARES Act"), which was signed into law on March 27, 2020 and interagency guidance from the federal banking agencies when determining if a borrower's modification is subject to a TDR classification. If it is determined that the modification does not meet the criteria under the CARES Act or interagency guidance to be excluded from TDR classification, the Company evaluates the loan modifications under its existing TDR framework. Loans subject to forbearance under the COVID-19 loan modification program are not reported as past due or placed on non-accrual status during the forbearance time period, and interest income continues to be recognized over the contractual life of the loans.

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 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-impaired loans 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.  When determining the appropriate historical loss and qualitative factors, management took into consideration the impact of the COVID-19 pandemic on such factors as the national and state unemployment rates and related trends, the amount of and timing of financial assistance provided by the government, consumer spending levels and trends, industries significantly impacted by the COVID-19 pandemic, and the Company's COVID-19 loan modification program. The appropriateness of the allowance for loan losses is estimated based upon these factors and trends identified by management at the time the consolidated financial statements are prepared.

A loan is considered impaired when it is probable that the Company 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 estimated net realizable value 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 and furniture and equipment - three to seven 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 undiscounted 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, 2020 or 2019 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. 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 values 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. Costs relating to development and improvement of the properties or assets are capitalized, while costs relating to holding the properties or assets are expensed.

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 in a business combination exceeds the estimated fair value of the net identified tangible and intangible assets acquired and liabilities assumed.  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. For purposes of goodwill impairment testing, the services offered through the Bank and its subsidiary are managed as one strategic unit and represent the Company's only reporting unit.

The annual goodwill impairment test begins with a qualitative assessment of whether it is "more likely than not" that the reporting unit's fair value is less than its carrying amount. If an entity concludes that it is not "more likely than not" that the fair value of a reporting unit is less than its carrying amount, it need not perform a two-step impairment test. If the Company's qualitative assessment concluded that it is "more likely than not" that the fair value of its reporting unit is less than its carrying amount, it must perform the two-step impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized, if any. The first step of the goodwill impairment test compares the estimated fair value of the reporting unit with its carrying amount, or the book value, including goodwill. If the estimated fair value of the reporting unit equals or exceeds its book value, goodwill is considered not impaired, and the second step of the impairment test is unnecessary.

The second step, if necessary, measures the amount of goodwill impairment loss to be recognized. The reporting unit must determine fair value for all assets and liabilities, excluding goodwill. The net of the assigned fair value of assets and liabilities is then compared to the book value of the reporting unit, and any excess book value becomes the implied fair value of goodwill. If the carrying amount of the goodwill exceeds the newly calculated implied fair value of goodwill, an impairment loss is recognized in the amount required to write-down the goodwill to the implied fair value.

Management's qualitative assessment takes into consideration macroeconomic conditions, industry and market considerations, cost or margin factors, financial performance and the share price of the Company's common stock. The Company performed its fiscal year 2020 goodwill impairment test during the quarter ended June 30, 2020 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, 2020 and the step one test concluded that the reporting unit's fair value was more than its recorded value and, therefore, step two of the analysis was not necessary. Accordingly, the recorded value of goodwill as of May 31, 2020 was not impaired.

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 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. Any change in these indicators 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, 2020, management believes that there were no events or changes in the circumstances since May 31, 2020 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. If adverse economic conditions or the recent decrease in the Company's stock price and market capitalization as a result of the COVID-19 pandemic were deemed to be other than temporary, it may significantly affect the fair value of the Company's goodwill and may trigger impairment charges. Any impairment charge could have a material adverse effect on the Company's results of operation and financial condition.

CDI

CDI represents the future economic benefit of the potential cost savings from acquiring core deposits as part of a business combination compared to the cost of alternative funding sources. CDI is amortized to non-interest expense using an accelerated method based on an estimated runoff of related deposits over a period of ten years. CDI is evaluated for impairment whenever events or changes in circumstances indicate that its carrying amount may not be recoverable, with any changes in estimated useful life accounted for prospectively over the revised remaining life.

Servicing Rights

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. Servicing rights are capitalized at estimated fair value when acquired through the origination of loans that are subsequently sold with the servicing rights retained. Servicing rights are amortized to servicing income on loans sold approximately in proportion to and over the period of estimated net servicing income.  The value of servicing rights 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 servicing rights must be stratified by one or more predominant risk characteristics of the underlying loans.  The Company stratifies its capitalized servicing rights 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 servicing rights 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 and various state income tax returns.  The Bank provides for income taxes separately and remits to (receives from) Timberland Bancorp amounts currently due (receivable).

Deferred 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, 2016.

ESOP

The Bank sponsors a leveraged ESOP; however, all ESOP debt was fully repaid during the year ended September 30, 2019. The debt of the ESOP was payable to Timberland Bancorp, was recorded as other borrowed funds of the Bank, and was eliminated in the consolidated financial statements. The shares of the Company's common stock pledged as collateral for the ESOP's debt were reported as unearned shares issued to the ESOP in the consolidated financial statements. As shares were released from collateral, compensation expense was recorded equal to the average market price of the shares for the period, and the shares became available for net income per common share calculations.  Dividends paid on unallocated shares reduced 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.  Stock option forfeitures are accounted for as they occur.

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 the Company's common stock during the period. Common stock equivalents arise from the assumed conversion of outstanding stock options.  Shares owned by the Bank’s ESOP that have not been allocated are not considered to be outstanding for the purpose of computing basic and diluted 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, 2020, 2019 and 2018 totaled $78,000, $69,000 and $94,000, respectively.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers, which created FASB Accounting Standards Codification ("ASC") Topic 606 ("ASC 606"). The core principle of ASC 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASC 606 was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company adopted ASC 606 on October 1, 2018 using the modified retrospective approach. Therefore, the comparative information has not been adjusted and continues to be reported under the superseded ASC 605. There was no cumulative effect adjustment as of October 1, 2018, and there were no material changes to the timing or amount of revenue recognized for the year ended September 30, 2019; however, additional disclosures were incorporated in the footnotes upon adoption. The majority of the Company's revenue is comprised of interest income from financial assets, which is explicitly excluded from the scope of ASC 606. The Company elected to apply the practical expedient pursuant to ASC 606 and therefore does not disclose information about remaining performance obligations that have an original expected term of one year or less and allows the Company to expense costs related to obtaining a contract as incurred when the amortization period would have been one year or less. See Note 24 for additional information.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 generally requires equity investments - except those accounted for under the equity method of accounting or those that result in consolidation of the investee - to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. ASU 2016-01 is intended to simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. ASU 2016-01 also eliminates certain disclosures related to the fair value of financial instruments and requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. ASU 2016-01 was effective for fiscal years beginning after December 15, 2017, including interim periods

within those fiscal years. The Company adopted ASU 2016-01 on October 1, 2018. As required by ASU 2016-01, on October 1, 2018 the Company recorded a one-time cumulative effect adjustment of $63,000 representing net unrealized losses on equity securities (mutual funds) between accumulated other comprehensive loss and retained earnings on the accompanying consolidated balance sheet. Additionally, the fair values of financial instruments for disclosure purposes were computed using an exit price notion and deposits with no stated maturity are no longer included in the fair value disclosures in Note 22.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which created FASB ASC Topic 842 ("ASC 842") and 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 ASC 842 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 generally on a 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. ASC 842 also changes disclosure requirements related to leasing activities and requires certain qualitative disclosures along with specific quantitative disclosures. ASC 842 also provides an optional transition method for adoption, under which an entity initially applies ASC 842 at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity's reporting for the comparative periods presented in the financial statements in which it adopts ASC 842 will continue to be in accordance with current GAAP. ASC 842 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early application of ASC 842 is permitted. The Company adopted the provisions of ASC 842 effective October 1, 2019 utilizing the optional transition method and will not restate comparative periods. The Company also elected the package of practical expedients permitted under ASC 842's transition guidance, which allows the Company to carryforward its historical lease classifications and its assessment as to whether a contract is or contains a lease. The Company also elected to not recognize lease assets and lease liabilities for leases with an initial term of 12 months or less. As a result of adopting ASC 842, ROU assets and operating lease liabilities increased by $2.89 million on October 1, 2019.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses, as amended by ASU 2018-19, ASU 2019-04 and ASU 2019-05. This ASU replaces the existing incurred losses methodology with a current expected 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 as a reduction of the carrying amount. ASU 2016-13 also changes the accounting for purchased credit-impaired debt securities and loans. ASU 2016-13 retains many of the current disclosure requirements in GAAP and expands certain disclosure requirements. ASU 2016-13 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Upon adoption, the Company expects a change in the processes and procedures to calculate the allowance for loan losses, including changes in the assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. In addition, the current policy for other-than-temporary impairment on investment securities available for sale will be replaced with an allowance approach. The Company is reviewing the requirements of ASU 2016-13 and has begun developing and implementing processes and procedures to ensure it is fully compliant with the amendments at the adoption date. At this time, the Company anticipates the allowance for loan losses will increase as a result of the implementation of this ASU; however, until its evaluation is complete, the magnitude of the increase will be unknown.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment. This ASU simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value of its assets and liabilities (including unrecognized assets and liabilities) at the impairment testing date following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by

which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax

deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. ASU 2017-04 is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2022.

The adoption ASU 2017-04 is not expected to a have a material impact on the Company's future consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This ASU shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. This ASU was effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018. The Company adopted ASU 2017-08 effective October 1, 2019 and it did not have a material impact on the Company's consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU was issued to provide clarity as to when to apply modification accounting when there is a change in the terms or conditions of a share-based payment award. According to the ASU, an entity should account for the effects of a modification unless the fair value, vesting conditions, and balance sheet classification of the award are the same after the modification as compared to the original award prior to modification. ASU 2017-09 was effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The Company adopted ASU 2017-09 effective October 1, 2018 and it did not have a material impact on the Company's consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This ASU was issued to expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. Previously, these awards were recorded at the fair value of consideration received or the fair value of the equity instruments issued and were measured at the earlier of the commitment date or the date performance was completed. The amendments in this ASU require nonemployee share-based payment awards to be measured at the grant-date fair value of the equity instrument. ASU 2018-07 was effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018. The Company adopted ASU 2018-07 effective October 1, 2019 and it did not have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements. The following disclosure requirements were removed from ASC Topic 820, Fair Value Measurement: (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; and (3) the valuation process for Level 3 fair value measurements. This ASU clarifies that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. This ASU adds the following disclosure requirements for Level 3 measurements: (1) changes in unrealized gains and losses for the period included in other comprehensive income for the recurring Level 3 fair value measurements held at the end of the reporting period, and (2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. ASU 2018-13 was effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted ASU 2018-13 effective October 1, 2020 and it is not expected to have a material impact on the Company's future consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40), Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this ASU broaden the scope of ASC Subtopic 350-40 to include costs incurred to implement a hosting arrangement that is a service contract. The amendments align the requirements for capitalizing implementation costs incurred

in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The costs are capitalized or expensed depending on the nature of the costs and the project stage during which they are incurred, consistent with the accounting for internal-use software costs. The amendments in this ASU result in consistent capitalization of implementation costs of a hosting arrangement that is a service contract and implementation costs incurred 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 in this ASU. ASU 2018-15 was effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted ASU 2018-15 effective October 1, 2020 and it is not expected to have a material impact on the Company's future consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidelines. ASU 2019-12 is effective for fiscal years beginning after December 15, 2021,

including interim periods within fiscal years. The adoption of ASU 2019-12 is not expected to have a material impact on the Company's future consolidated financial statements.

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU applies to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate ("LIBOR") or other rate references expected to be discontinued because of reference rate reform. The ASU permits an entity to make necessary modifications to eligible contracts or transactions without requiring contract remeasurement or reassessment of a previous accounting determination. This ASU is effective for all entities as of March 12, 2020 through December 31, 2022. The Company has not adopted ASU 2020-04 as of September 30, 2020. The adoption of ASU 2020-04 is not expected to have a material impact on the Company's future consolidated financial statements.

On March 22, 2020, federal banking regulators issued an interagency statement that included guidance on their approach for the accounting of loan modifications in light of the economic impact of the COVID-19 pandemic. The guidance interprets current accounting standards and indicates that a lender can conclude that a borrower is not experiencing financial difficulty if short-term modifications are made in response to COVID-19, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant related to the loans in which the borrower is less than 30 days past due on its contractual payments at the time a modification is implemented. The agencies confirmed in working with the staff of the FASB that short-term modification made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not troubled debt restructurings.

Business Combinations [Abstract]

Business Combinations

Business Combination

On October 1, 2018, the Company completed the South Sound Acquisition. The primary reason for the acquisition was to expand the Company's presence along Washington State's economically important I-5 corridor.

Pursuant to the terms of the merger agreement, South Sound Bank shareholders received 0.746 of a share of the Company's common stock and $5.68825 in cash per share of South Sound Bank common stock. The Company issued 904,826 shares of its common stock (valued at $28,267,000 based on the Company's closing stock price on September 30, 2018 of $31.24 per share) and paid $6,903,000 in cash in the transaction for total consideration paid of $35,170,000.

The South Sound Acquisition constitutes a business combination as defined by GAAP, which establishes principles and requirements for how the acquirer in a business combination recognizes and measures in its financial statements the identifiable assets acquired and liabilities assumed. The Company was considered the acquirer in this transaction. Accordingly, the estimated fair values of the acquired assets, including the identifiable intangible assets, and the assumed liabilities in the South Sound Acquisition were measured and recorded as of October 1, 2018. The excess of the total consideration paid over the fair value of the net assets acquired was allocated to goodwill. The South Sound Acquisition resulted in $9,481,000 of goodwill. The goodwill arising from this transaction consists largely of the synergies and expected economies of scale from combining the operations of the Company and South Sound Bank. This goodwill is not deductible for tax purposes.

In most instances, determining the estimated fair values of the acquired assets and assumed liabilities requires the Company to estimate cash flows expected to result from those assets and liabilities and to discount those cash flows at the appropriate rate of interest. Differences may arise between contractually required payments and the expected cash flows at the acquisition date due to items such as estimated credit losses, prepayments or early withdrawal, and other factors. One of the most significant of those determinations relates to the valuation of acquired loans. For such loans, the excess of cash flows expected at acquisition over the estimated fair value is recognized as interest income over the remaining lives of the loans. In accordance with GAAP, there was no carry-over of South Sound Bank's previously established allowance for loan losses.

The following table summarizes the fair value of consideration paid, the estimated fair values of assets acquired and liabilities assumed as of the acquisition date, and the resulting goodwill relating to the transaction:

Total identifiable net assets acquired	$	26,041	$	(352)	25,689
Goodwill recognized					$	9,481

The acquired loan portfolio was valued using Level 3 inputs (see Note 22) and included the use of present value techniques, including cash flow estimates and incorporated assumptions that the Company believes marketplace participants would use in estimating fair values.

The operating results of the Company for the years ended September 30, 2020 and 2019 include the operating results produced by the net assets acquired in the South Sound Acquisition since the October 1, 2018 acquisition date. The Company determined

that the disclosure requirements related to the amounts of revenues and earnings from the net assets acquired in the South Sound Acquisition since the October 1, 2018 acquisition date is impracticable. The financial activity and operating results of the net assets acquired in the South Sound Acquisition were commingled with the Company's financial activity and operating results as of the acquisition date.

During the year ended September 30, 2020, the Company incurred acquisition-related expenses of $2,000 related to the South Sound Acquisition. During the year ended September 30, 2019, the Company incurred acquisition-related expenses of $462,000 related to the South Sound Acquisition, of which $317,000 is included in data processing and $145,000 is included in

professional fees in the accompanying consolidated statement of income. During the year ended September 30, 2018, the Company incurred acquisition-related expenses of $616,000 related to the South Sound Acquisition, which are all included in professional fees in the accompanying consolidated statement of income. South Sound Bank incurred acquisition-related expenses of $1,598,000 for the fiscal year ended September 30, 2018 related to the South Sound Acquisition.

The Company has evaluated the investment securities in the above tables and has determined that the decline in their fair value is temporary.  The unrealized losses are primarily due to changes in market interest rates and spreads in the market for mortgage-related products. The fair value of these securities is expected to recover as the securities approach their maturity dates and/or as the pricing spreads narrow on mortgage-related securities.  The Company has the ability and the intent to hold the investments until the fair value of these securities recovers.  Additional deterioration in market and economic conditions related to the COVID-19 pandemic may, however, have an adverse impact on credit quality in the future and result in OTTI charges.

The Company bifurcates OTTI into (1) amounts related to credit losses which are recognized through earnings and (2) amounts related to all other factors which are recognized as a component of other comprehensive income (loss).

To determine the component of the gross OTTI related to credit losses, the Company compared the amortized cost basis of the OTTI security to the present value of its revised expected cash flows, discounted using its pre-impairment yield. The revised expected cash flow estimates for individual securities are based primarily on an analysis of default rates, prepayment speeds and

third-party analytic reports.  Significant judgment by management is required in this analysis that includes, but is not limited to, assumptions regarding the collectability of principal and interest, net of related expenses, on the underlying loans.

The following table presents a summary of the significant inputs utilized to measure management’s estimates of the credit loss component on OTTI securities as of September 30, 2020, 2019 and 2018:

	Range				Weighted
	Minimum		Maximum		Average
September 30, 2020
Constant prepayment rate	6.00	%	15.00	%	8.97	%

Significant Concentrations of Credit Risk

Most of the Company’s lending activity is with customers located in the state of Washington and involves real estate.  At September 30, 2020, the Company had $934,351,000 (including $100,558,000 of undisbursed construction loans in process) in loans secured by real estate, which represented 82.4% of total loans receivable.  The real estate loan portfolio is primarily secured by one- to four-family properties, multi-family properties, land, and a variety of commercial real estate property types.  At September 30, 2020, there were no concentrations of real estate loans to a specific industry or secured by a specific collateral type that equaled or exceeded 20% of the Company’s total loan portfolio, other than loans secured by one-to four-

family properties.  The ultimate collectability of a substantial portion of the loan portfolio is susceptible to changes in economic and market conditions in the region and the impact of those changes on the real estate market.  The Company typically originates real estate loans with loan-to-value ratios of no greater than 90%.  Collateral and/or guarantees are required for all loans.

Related Party Loans

Certain related parties of the Company, principally Bank directors and officers, are loan customers of the Bank in the ordinary course of business.  Such related party loans were performing according to their repayment terms at September 30, 2020 and 2019.  Activity in related party loans during the years ended September 30, 2020, 2019 and 2018 was as follows (dollars in thousands):

	2020		2019		2018
Balance, beginning of year	$	94	$	119	$	741
New loans or borrowings	178		1		368
Repayments and reclassifications	(24)		(26)		(990)
Balance, end of year	$	248	$	94	$	119

Loan Segment Risk Characteristics

The Company believes that its loan classes are the same as its loan segments.

One- To Four-Family Residential Lending:  The Company originates both fixed-rate and adjustable-rate loans secured by one- to four-family residences.  A portion of the fixed-rate one- to four-family loans are sold in the secondary market for asset/liability management purposes and to generate non-interest income.  The Company’s lending policies generally limit the maximum loan-to-value on one- to four-family loans to 90% of the lesser of the appraised value or the purchase price.  However, the Company usually obtains private mortgage insurance on the portion of the principal amount that exceeds 80% of the appraised value of the property.

Multi-Family Lending: The Company originates loans secured by multi-family dwelling units (more than four units).  Multi-family lending generally affords the Company an opportunity to receive interest at rates higher than those generally available from one- to four-family residential lending.  However, loans secured by multi-family properties usually are greater in amount, more difficult to evaluate and monitor and, therefore, involve a greater degree of risk than one- to four-family residential mortgage loans.  Because payments on loans secured by multi-family properties are often dependent on the successful operation and management of the properties, repayment of such loans may be affected by adverse conditions in the real estate market or economy.  The Company attempts to minimize these risks by scrutinizing the financial condition of the borrower, the quality of the collateral and the management of the property securing the loan.

Commercial Mortgage Lending: The Company originates commercial real estate loans secured by properties such as office buildings, retail/wholesale facilities, motels, restaurants, mini-storage facilities and other commercial properties.  Commercial real estate lending generally affords the Company an opportunity to receive interest at higher rates than those available from one- to four-family residential lending.  However, loans secured by such properties usually are greater in amount, more difficult to evaluate and monitor and, therefore, involve a greater degree of risk than one- to four-family residential mortgage loans. Because payments on loans secured by commercial properties are often dependent on the successful operation and management of the properties, repayment of these loans may be affected by adverse conditions in the real estate market or economy.  The Company attempts to mitigate these risks by generally limiting the maximum loan-to-value ratio to 80% and scrutinizing the financial condition of the borrower, the quality of the collateral and the management of the property securing the loan.

Construction Lending:  The Company currently originates the following types of construction loans: custom construction loans, owner/builder construction loans, speculative construction loans, commercial real estate construction loans, multi-family construction loans and land development loans. 

Construction lending affords the Company the opportunity to achieve higher interest rates and fees with shorter terms to maturity than does its single-family permanent mortgage lending.  Construction lending, however, is generally considered to involve a higher degree of risk than one- to four family residential lending because of the inherent difficulty in estimating both a property’s value at completion of the project and the estimated cost of the project.  The nature of these loans is such that they are generally more difficult to evaluate and monitor.  If the estimated cost of construction proves to be inaccurate, the Company may be required to advance funds beyond the amount originally committed to complete the project.  If the estimate of value upon completion proves to be inaccurate, the Company may be confronted with a project whose value is insufficient to assure full repayment, and the Company may incur a loss.  Projects may also be jeopardized by disagreements between borrowers and builders and by the failure of builders to pay subcontractors.  Loans to construct homes for which no purchaser has been

identified carry more risk because the payoff for the loan depends on the builder’s ability to sell the property prior to the time that the construction loan is due.  The Company attempts to mitigate these risks by adhering to its underwriting policies, disbursement procedures and monitoring practices.

Construction Lending – Custom and Owner/Builder:  Custom construction and owner/builder construction loans are originated to home owners and are typically refinanced into permanent loans at the completion of construction.

Construction Lending – Speculative One- To Four-Family: Speculative one-to four-family construction loans are made to home builders and are termed “speculative” because the home builder does not have, at the time of the loan origination, a signed contract with a home buyer who has a commitment for permanent financing with the Company or another lender for the finished home.  The home buyer may be identified either during or after the construction period. 

Construction Lending – Commercial:  Commercial construction loans are originated to construct properties such as office buildings, hotels, retail rental space and mini-storage facilities.

Construction Lending – Multi-Family:  Multi-family construction loans are originated to construct apartment buildings and condominium projects.

Construction Lending - Land Development: Land development loans are originated to real estate developers for the purpose of developing residential subdivisions. The Company is currently originating land development loans on a limited basis.

Land Lending: The Company originates loans for the acquisition of land upon which the purchaser can then build or make improvements necessary to build or to sell as improved lots.  Loans secured by undeveloped land or improved lots involve greater risks than one- to four-family residential mortgage loans because these loans are more difficult to evaluate.  If the estimate of value proves to be inaccurate, in the event of default or foreclosure, the Company may be confronted with a property value which is insufficient to assure full repayment.  The Company attempts to minimize this risk by generally limiting the maximum loan-to-value ratio on land loans to 75%.

Consumer Lending – Home Equity and Second Mortgage:   The Company originates home equity lines of credit and second mortgage loans.  Home equity lines of credit and second mortgage loans have a greater credit risk than one- to four-family residential mortgage loans because they are secured by mortgages subordinated to the existing first mortgage on the property, which may or may not be held by the Company.  The Company attempts to mitigate these risks by adhering to its underwriting policies in evaluating the collateral and the credit-worthiness of the borrower.

Consumer Lending – Other: The Company originates other consumer loans, which include automobile loans, boat loans, motorcycle loans, recreational vehicle loans, savings account loans and unsecured loans.  Other consumer loans generally have shorter terms to maturity than mortgage loans.  Other consumer loans generally involve a greater degree of risk than do residential mortgage loans, particularly in the case of consumer loans that are unsecured or secured by rapidly depreciating assets such as automobiles.  In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation.  The Company attempts to mitigate these risks by adhering to its underwriting policies in evaluating the credit-worthiness of the borrower.

Commercial Business Lending:  The Company originates commercial business loans which, excluding SBA PPP loans, are generally secured by business equipment, accounts receivable, inventory or other property.  The Company also generally obtains personal guarantees from the business owners based on a review of personal financial statements.  Commercial business lending generally involves risks that are different from those associated with residential and commercial real estate lending.  Real estate lending is generally considered to be collateral based lending with loan amounts based on predetermined loan to collateral values, and liquidation of

the underlying real estate collateral is viewed as the primary source of repayment in the event of borrower default.  Although commercial business loans are often collateralized by equipment, inventory, accounts receivable or other business assets, the

liquidation of collateral in the event of a borrower default is often an insufficient source of repayment, because accounts receivable may be uncollectible and inventories and equipment may be obsolete or of limited use.  Accordingly, the repayment

of a commercial business loan depends primarily on the credit-worthiness of the borrower (and any guarantors), while the liquidation of collateral is a secondary and potentially insufficient source of repayment.  The Company attempts to mitigate

these risks by adhering to its underwriting policies in evaluating the management of the business and the credit-worthiness of the borrowers and the guarantors.

SBA PPP: The CARES Act, which was signed into law on March 27, 2020, authorized the SBA to temporarily guarantee loans under a new loan program called PPP. As a qualified SBA lender, the Company was automatically authorized to originate PPP loans upon commencement of the program in April 2020 through the conclusion of the PPP on August 8, 2020. The SBA guarantees 100% of PPP loans made to eligible borrowers and the entire amount of the borrower's PPP loan, including any accrued interest, is eligible to be forgiven and repaid by the SBA. PPP loans have: (a) an interest rate of 1%, (b) a two-year loan term to maturity for loans approved by the SBA prior to June 5, 2020 and a five-year maturity for loans approved thereafter; and (c) principal and interest payments deferred for at least six months from the date of disbursement.

Credit Quality Indicators

The Company uses credit risk grades which reflect the Company’s assessment of a loan’s risk or loss potential.  The Company categorizes loans into risk grade categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors such as the estimated fair value of the collateral.  The Company uses the following definitions for credit risk ratings as part of the on-going monitoring of the credit quality of its loan portfolio:

Pass:  Pass loans are defined as those loans that meet acceptable quality underwriting standards.

Watch:  Watch loans are defined as those loans that still exhibit acceptable quality but have some concerns that justify greater attention.  If these concerns are not corrected, a potential for further adverse categorization exists.  These concerns could relate to a specific condition peculiar to the borrower, its industry segment or the general economic environment.

Special Mention: Special mention loans are defined as those loans deemed by management to have some potential weaknesses that deserve management’s close attention.  If left uncorrected, these potential weaknesses may result in the deterioration of the payment prospects of the loan.  

Substandard:  Substandard loans are defined as those loans that are inadequately protected by the current net worth and paying capacity of the obligor, or of the collateral pledged.  Loans classified as substandard have a well-defined weakness or weaknesses that jeopardize the repayment of the debt.  If the weakness or weaknesses are not corrected, there is the distinct possibility that some loss will be sustained.

Doubtful: Loans in this classification have the weaknesses of substandard loans with the additional characteristic that the weaknesses make the collection or liquidation in full on the basis of currently existing facts, conditions and values questionable, and there is a high possibility of loss. At September 30, 2020 and 2019, there were no loans classified as doubtful.

Loss:  Loans in this classification are considered uncollectible and of such little value that continuance as an asset is not warranted.  This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this loan even though partial recovery may be realized in the future. At September 30, 2020 and 2019, there were no loans classified as loss.

CARES Act provided guidance around the modification of loans as a result of the COVID-19 pandemic, which outlined, among other criteria, that short-term modifications made on a good faith basis to borrowers who were current as defined under the CARES Act prior to any relief, are not TDRs. This includes short-term (e.g. six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. Borrowers are considered current under the CARES Act and related regulatory guidance if they are less than 30 days past due on their contractual payments at the time a modification program is implemented. In response to requests from borrowers, the Company made payment deferral modifications (typically 90-day payment deferrals with interest continuing to accrue or scheduled to be paid monthly) on a number of loans. The majority of these borrowers had resumed making payments as of September 30, 2020 and only five loans totaling $5,870,000 remained on deferral status under COVID-19 loan modification forbearance agreements as of that date. Loan modifications in accordance with the CARES Act and related regulatory guidance are still subject to an evaluation in regard to determining whether or not a loan is deemed to be impaired.

The following table details the COVID-19 loan modifications, still on deferral status, as of September 30, 2020 (dollars in thousands):

Income Taxes

Income Taxes

On December 22, 2017, the federal government enacted the Tax Cuts and Jobs Act (the "Tax Act"). The Tax Act significantly revised the future ongoing federal corporate income tax by, among other things, decreasing the federal corporate income tax rate to 21.0% from 35.0% effective January 1, 2018. As the Company has a September 30 fiscal year-end, the lower corporate income tax rate was phased in, resulting in a blended federal income tax rate of approximately 24.5% for the Company's fiscal year ended September 30, 2018, and 21.0% for subsequent fiscal years. In addition, the reduction of the corporate federal income tax rate required the Company to revalue its deferred tax assets and liabilities based on the lower federal income tax rate of 21.0%.

As a result of the Tax Act, during the year ended September 30, 2018, the Company recorded a one-time income tax expense of $548,000 in conjunction with remeasuring its net deferred tax assets. The impact of using the 24.5% blended federal income tax rate for the year ended September 30, 2018 versus a 35.0% rate reduced the provision for income taxes by approximately $2.21 million, which was partially offset by the $548,000 one-time net deferred tax asset remeasurement.

The components of the provision for income taxes for the years ended September 30, 2020, 2019 and 2018 were as follows (dollars in thousands):

Employee Stock Ownership and 401(k) Plan

Employee Stock Ownership and 401(k) Plan The Timberland Bank Employee Stock Ownership and 401(k) Plan (“KSOP”) is comprised of two components, the ESOP and the 401(k) Plan.  The KSOP benefits employees with at least one year of service who are 18 years of age or older.  The Bank

may fund the ESOP with contributions of cash or stock, and may fund the 401(k) Plan with contributions of cash.  Employee vesting occurs over six years.

ESOP

In January 1998, the ESOP borrowed $7,930,000 from the Company to purchase 1,058,000 shares of common stock of the Company.  The loan was repaid primarily from the Bank’s contributions to the ESOP and was fully repaid by March 31, 2019. The interest rate on the loan was 8.5%. Interest expense on the ESOP debt was $9,000 and $53,000 for the years ended September 30, 2019 and 2018, respectively.

The amount of the Bank's annual contribution was discretionary, except that it must have been sufficient to enable the ESOP to service its debt.  All dividends received by the ESOP were used to pay debt service through March 31, 2019. The dividends received after March 31, 2019 have been paid directly to participants. Dividends of $176,000 and $291,000 were used to service the debt during the years ended September 30, 2019 and 2018, respectively.  As the Plan made each payment of principal and interest, an appropriate percentage of stock was released and allocated annually to eligible employee accounts, in accordance with applicable regulations. As of September 30, 2020, an aggregate of 642,302 ESOP shares, which were previously released for allocation to participants, had been distributed to participants.

Shares held by the ESOP as of September 30, 2020, 2019 and 2018 were classified as follows:

	2020	2019	2018
Unallocated shares	—	—	17,639
Shares released for allocation	415,698	425,281	451,644
Total ESOP shares	415,698	425,281	469,283

The approximate fair market value of the ESOP’s unallocated shares at September 30, 2018 was $551,000.  There was no compensation expense recognized for the ESOP for the year ended September 30, 2020. Compensation expense recognized for the ESOP for the years ended September 30, 2019 and 2018 was $318,000, and $823,000, respectively.

401(k) Plan

Eligible employees may contribute a portion of their wages to the 401(k) Plan up to the maximum established under the Internal Revenue Code.  Contributions by the Bank are at the discretion of the Board except for a safe harbor contribution of 3% of eligible employees' wages, which is mandatory according to the plan document.  Bank contributions totaled $908,000, $743,000 and $379,000 for the years ended September 30, 2020, 2019 and 2018, respectively.

Under the Company's 2014 Equity Incentive Plan, the Company is able to grant options and awards of restricted stock (with or without performance measures) for up to 352,366 shares of common stock to employees, officers, directors and directors emeriti.  Under the Company's 2019 Equity Incentive Plan, which was approved by shareholders on January 28, 2020, the Company is able to grant options and awards or restricted stock (with or without performance measures) for up to 350,000 shares of common stock, of which 300,000 share are reserved to be awarded to employees and officers and 50,000 shares are reserved to be awarded to directors and directors emeriti. Shares issued may be purchased in the open market or may be issued from authorized and unissued shares. The exercise price of each option equals the fair market value of the Company’s common stock on the date of grant.  Generally, options and restricted stock vest in 20% annual installments on each of the five anniversaries from the date of the grant, and options generally have a maximum contractual term of ten years from the date of the grant.  At September 30, 2020, there were 25,556 shares of common stock available which may be awarded as options or restricted stock pursuant to future grants under the 2014 Equity Incentive Plan. At September 30, 2020 there were 299,500 shares of common stock available which may be awarded as options or restricted stock pursuant to future grants under the 2019 Equity Incentive Plan.

At both September 30, 2020 and 2019, there were no unvested restricted stock awards. There were no restricted stock grants awarded during the years ended September 30, 2020, 2019 and 2018.

Stock option activity for the years ended September 30, 2020, 2019 and 2018 is summarized as follows:

	Number of Shares	Weighted Average Exercise Price
Outstanding September 30, 2017	380,120	$	13.23

The aggregate intrinsic value of options exercised during the years ended September 30, 2020 and 2019 was $640,000 and $864,000, respectively.

The Company uses the Black-Scholes option pricing model to estimate the fair value of stock-based awards with the weighted average assumptions noted in the following table.  The risk-free interest rate is based on the rate of a U.S. Treasury security with a similar term as the expected life of the stock option at the particular grant date.  The expected life is based on historical data, vesting terms and estimated exercise dates. The expected dividend yield is based on the most recent quarterly dividend on an annualized basis in effect at the time the options were granted, adjusted, if appropriate, for management's expectations regarding future dividends.  The expected volatility is based on historical volatility of the Company’s stock price.  There were 45,950 options granted during the year ended September 30, 2018 with an aggregate grant date fair value of $206,000. There were 46,840 options granted during the year ended September 30, 2019 with an aggregate grant date fair value of $240,000. There were 69,150 options granted during the year ended September 30, 2020 with an aggregate grant date fair value of $187,000.

The weighted average assumptions for options granted during the years ended September 30, 2020, 2019 and 2018 were as follows:

	2020			2019			2018
Expected volatility	33		%	29		%	17		%
Expected life (in years)	5			5			5
Expected dividend yield	5.36		%	3.28		%	2.61		%
Risk free interest rate	0.28		%	1.53		%	2.97		%
Grant date fair value per share	$	2.70		$	5.12		$	4.48

There were 58,548 options that vested during the year ended September 30, 2020 with a total fair value of $176,000. There were 77,540 options that vested during the year ended September 30, 2019 with a total fair value of $203,000. There were 76,450 options that vested during the year ended September 30, 2018 with a total fair value of $181,000.

At September 30, 2020, there were 159,192 unvested options with an aggregate grant date fair value of $571,000, all of which the Company assumes will vest.  The unvested options had an aggregate intrinsic value of $99,000 at September 30, 2020.  At September 30, 2019, there were 160,750 unvested options with an aggregate grant date fair value of $605,000.

Commitments and Contingencies

Commitments and Contingencies

In the normal course of business the Company is party to financial instruments with off-balance-sheet risk to meet the financing needs of its customers.  These financial instruments include commitments to extend credit.  These instruments involve, to varying degrees, elements of credit risk not recognized in the consolidated balance sheets. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments.  The Bank uses the same credit policies in making commitments as it does for on-balance-sheet instruments.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract.  Since commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.  The Company evaluates each customer’s credit-worthiness on a case-by-case basis.  The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party.  However, such loan to value ratios will subsequently change, based on increases and decreases in the supporting collateral values.  Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate, land and income-producing commercial properties.

A summary of the Company’s commitments at September 30, 2020 and 2019 is as follows (dollars in thousands):

	2020		2019
Undisbursed portion of construction loans in process (see Note 5)	$	100,558	$	92,226
Undisbursed lines of credit	103,030		80,184
Commitments to extend credit	38,581		16,578

The Company maintains a separate reserve for losses related to unfunded loan commitments.  Management estimates the amount of probable losses related to unfunded loan commitments by applying the loss factors used in the allowance for loan loss methodology to an estimate of the expected amount of funding and applies this adjusted factor to the unused portion of unfunded loan commitments.  The reserve for unfunded loan commitments totaled $384,000 and $241,000 at September 30, 2020 and 2019, respectively.  These amounts are included in other liabilities and accrued expenses in the accompanying

consolidated balance sheets.  Increases (decreases) in the reserve for unfunded loan commitments are recorded in non-interest expense in the accompanying consolidated statements of income.

The Bank has an employee severance compensation plan which expires in 2027 and which provides severance pay benefits to eligible employees in the event of a change in control of Timberland Bancorp or the Bank (as defined in the plan).  In general, all employees with two or more years of service will be eligible to participate in the plan.  Under the plan, in the event of a change in control of Timberland Bancorp or the Bank, eligible employees who are terminated or who terminate employment (but only upon the occurrence of events specified in the plan) within 12 months of the effective date of a change in control would be entitled to a payment based on years of service or officer rank with the Bank.  The maximum payment for any eligible employee would be equal to 18 months of the employee’s current compensation.

The Company has employment agreements with the Chief Executive Officer and the Chief Financial Officer which provide for a severance payment and other benefits if the officers are involuntarily terminated following a change in control of the Company or the Bank. The maximum value of the severance benefits under the employment agreements is 2.99 times the officer's average annual compensation during the five-year period prior to the effective date of the change in control.

Because of the nature of its activities, the Company is subject to various pending and threatened legal actions which arise in the ordinary course of business.  In the opinion of management, liabilities arising from these claims, if any, will not have a material effect on the consolidated financial position of the Company.

Regulatory Matters

Regulatory Matters

The Bank, as a state-chartered, federally insured savings bank, is subject to the capital requirements established by the FDIC. Under the FDIC's capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank's assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by bank regulators that, if undertaken, could have a direct material effect on the Company's consolidated financial statements.

The minimum requirements are a common equity Tier 1 ("CET1") capital ratio of 4.5%, a Tier 1 capital ratio of 6.0%, a total capital ratio of 8.0% and a leverage ratio of 4.0%. In addition to the minimum regulatory capital ratios, the Bank is required to maintain a capital conservation buffer consisting of additional CET1 capital greater than 2.5% of risk-weighted assets above the required minimum levels in order to avoid limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses based on percentages of retained income that could be utilized for such actions. At September 30, 2020, the Bank's CET1 capital exceeded the required capital conservation buffer.

At September 30, 2020 and 2019, the Bank exceeded all regulatory capital requirements. The Bank was categorized as "well capitalized" at September 30, 2020 and 2019 under the regulations of the FDIC. The following tables compare the Bank’s actual capital amounts at September 30, 2020 and 2019 to its minimum regulatory capital requirements and "Well Capitalized" regulatory capital at those dates (dollars in thousands):

Timberland Bancorp is a bank holding company registered with the Federal Reserve. Bank holding companies are subject to capital adequacy requirements of the Federal Reserve under the Bank Holding Company Act of 1956, as amended, and the regulations of the Federal Reserve. For a bank holding company with less than $3.0 billion in assets, the capital guidelines apply on a bank only basis, and the Federal Reserve expects the holding company's subsidiary bank to be well capitalized under the prompt corrective action regulations. If Timberland Bancorp were subject to regulatory guidelines for bank holding companies with $3.0 billion or more in assets at September 30, 2020, Timberland Bancorp would have exceeded all regulatory requirements.

The following table presents the regulatory capital ratios for Timberland Bancorp at September 30, 2020 and 2019 assuming Timberland Bancorp was subject to regulatory guidelines for bank holding companies with $3.0 billion or more in assets (dollars in thousands):

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Fair value is defined under GAAP as the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. GAAP requires that valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. GAAP also establishes a fair value hierarchy which prioritizes the valuation inputs into three broad levels. Based on the underlying inputs, each fair value measurement in its entirety is reported in one of three levels. These levels are:

Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2: Significant observable inputs other than quoted prices included within Level 1, such as quoted prices for similar (as opposed to identical) assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted prices that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs that reflect a company’s own assumptions about the assumptions market participants would use in pricing an asset or liability based on the best information available in the circumstances.

The Company's assets measured at fair value on a recurring basis consist of investment securities available for sale and investments in equity securities. The estimated fair values of MBS are based upon market prices of similar securities or observable inputs (Level 2). The estimated fair values of mutual funds are based upon quoted market prices (Level 1).

The Company had no liabilities measured at fair value on a recurring basis at September 30, 2020 and 2019. The Company's assets measured at estimated fair value on a recurring basis at September 30, 2020 and 2019 are as follows (dollars in thousands):

Total	$	958	$	22,532	$	—	$	23,490

There were no transfers among Level 1, Level 2 and Level 3 during the years ended September 30, 2020 and 2019.

The Company may be required, from time to time, to measure certain assets and liabilities at fair value on a non-recurring basis in accordance with GAAP.  These include assets that are measured at the lower of cost or market value that were recognized at fair value below cost at the end of the period.

The Company uses the following methods and significant assumptions to estimate fair value on a non-recurring basis:

Impaired Loans: The estimated fair value of impaired loans is calculated using the collateral value method or on a discounted cash flow basis. The specific reserve for collateral dependent impaired loans is based on the estimated fair value of the collateral less estimated costs to sell, if applicable.  In some cases, adjustments are made to the appraised values due to various factors including age of the appraisal, age of comparables included in the appraisal and known

changes in the market and in the collateral. Such adjustments may be significant and typically result in a Level 3 classification of the inputs for determining fair value. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly.

Investment Securities Held to Maturity: The estimated fair value of investment securities held to maturity is based upon the assumptions market participants would use in pricing the investment security.  Such assumptions include quoted market prices (Level 1), market prices of similar securities or observable inputs (Level 2) and unobservable inputs such as dealer quotes, discounted cash flows or similar techniques (Level 3).

OREO and Other Repossessed Assets, net:  OREO and other repossessed assets are recorded at estimated fair value less estimated costs to sell.  Estimated fair value is generally determined by management based on a number of factors, including third-party appraisals of estimated fair value in an orderly sale.  Estimated costs to sell are based on standard market factors.  The valuation of OREO and other repossessed assets is subject to significant external and internal judgment (Level 3).

The following table summarizes the balances of assets measured at estimated fair value on a non-recurring basis at September 30, 2020 (dollars in thousands):

	Estimated Fair Value

GAAP requires disclosure of estimated fair values for financial instruments.  Such estimates are subjective in nature, and significant judgment is required regarding the risk characteristics of various financial instruments at a discrete point in time.  Therefore, such estimates could vary significantly if assumptions regarding uncertain factors were to change.  In addition, as the Company normally intends to hold the majority of its financial instruments until maturity, it does not expect to realize many of the estimated amounts disclosed.  The disclosures also do not include estimated fair value amounts for certain items which are not defined as financial instruments but which may have significant value.  The Company does not believe that it would be practicable to estimate a fair value for these types of items as of September 30, 2020 and 2019.  Because GAAP excludes certain items from fair value disclosure requirements, any aggregation of the fair value amounts presented would not represent the underlying value of the Company. Additionally, in accordance with ASU 2016-01, which the Company adopted on October 1, 2018 on a prospective basis, the Company uses the exit price notion in calculating the fair values of financial instruments not measured at fair value on a recurring basis.

The recorded amounts and estimated fair values of financial instruments were as follows as of September 30, 2020 (dollars in thousands):

The Company assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations.  As a result, the estimated fair value of the Company’s financial instruments will change when interest rate levels change, and that change may either be favorable or unfavorable to the Company.  Management attempts to match maturities of assets and liabilities to the extent believed necessary to appropriately manage interest rate risk.  However, borrowers with fixed interest rate obligations are less likely to prepay in a rising interest rate environment and more likely to prepay in a falling

interest rate environment.  Conversely, depositors who are receiving fixed interest rates are more likely to withdraw funds before maturity in a rising interest rate environment and less likely to do so in a falling interest rate environment.  Management monitors interest rates and maturities of assets and liabilities, and attempts to manage interest rate risk by adjusting terms of new loans and deposits and by investing in securities with terms that mitigate the Company’s overall interest rate risk.

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer

Revenue from Contracts with Customers

In accordance with ASC 606, revenues are recognized when control of promised goods or services is transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services that are promised within each contract and identifies those that contain performance obligations, and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

ASC 606 applies to all contracts with customers to provide goods or services in the ordinary course of business, except for contracts that are specifically excluded from its scope. The majority of the Company's revenues are composed of interest income, deferred loan fee accretion, premium/discount accretion, gains on sales of loans and investments, BOLI net earnings, servicing income on loans sold and other loan fee income, which are not in the scope of ASC 606. Revenue reported as service charges on deposits, ATM and debit card interchange transaction fees, merchant services fees, non-deposit investment fees and escrow fees are within the scope of ASC 606. All of the Company's revenue from contracts with customers in the scope of ASC 606 is recognized in non-interest income with the exception of gains on sale of OREO and gains on sales/disposition of premises and equipment, which are included in non-interest expense. For the year ended September 30, 2020, the Company recognized $4,147,000 in services charges on deposits, $4,378,000 in ATM and debit card interchange fees, $273,000 in escrow fees and $22,000 in fee income from non-deposit investment sales, all considered within the scope of ASC 606. For the year ended September 30, 2019, the Company recognized $4,904,000 in service charges on deposits, $4,036,000 in ATM and debit card interchange fees, $197,000 in escrow fees and $46,000 in fee income from non-deposit investment sales, all considered within the scope of ASC 606.

Descriptions of the Company's revenue-generating activities that are within the scope of ASC 606 are as follows:

•Service Charges on Deposits: The Company earns fees from its deposit customers from a variety of deposit products and services. Non-transaction based fees such as account maintenance fees and monthly statement fees are considered to be provided to the customer under a day-to-day contract with ongoing renewals. Revenue for these non-transaction fees are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Transaction-based fees such as non-sufficient fund charges, stop payment charges and wire fees are recognized at the time the transaction is executed as the contract duration does not extend beyond the service performed.

•ATM and Debit Card Interchange Transaction Fees: The Company earns fees from cardholder transactions conducted through third party payment network providers which consist of interchange fees earned from the payment networks as a debit card issuer. These fees are recognized when the transaction occurs, but may settle on a daily or monthly basis.

•Escrow Fees: The Company earns fees from real estate escrow contracts with customers. The Company receives and disburses money and/or property per the customer's contract. Fees are recognized when the escrow contract closes.

•Fee income from Non-Deposit Investment Sales: The Company earns fees from contracts with customers for investment activities. Revenues are generally recognized on a monthly basis and are generally based on a percentage of the customer's assets under management or based on investment solutions that are implemented for the customer.

Summary of Significant Accounting Policies: Basis of Presentation (Policies)

12 Months Ended

Sep. 30, 2020

Accounting Policies [Abstract]

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 24 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.

Use of Estimates

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 any OTTI in the fair value of investment securities, the valuation of servicing rights, the valuation of OREO, the valuation of assets acquired and liabilities assumed in acquisitions and the valuation of goodwill for potential impairment.

Reclassification Policy

Certain prior year amounts have been reclassified to conform to the 2020 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.”

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.

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 maturities of 12 to 60 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

Investments in debt securities are classified upon acquisition as held to maturity or available for sale.  Investments in debt securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and reported at amortized cost.  Investments in debt securities classified as available for sale are reported 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 interest income 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 debt securities available for sale that are deemed to be other than temporary are recognized in earnings when identified.  The fair value of the debt security then becomes the new cost basis.  For individual debt 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 debt 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 debt 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 debt security’s cost basis and its fair value at the consolidated balance sheet date.  For individual debt 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 any 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, 2020 and 2019.

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, net deferred loan origination fees and the allowance for loan losses.

Interest on Loans, Non-accrual Loans and Loan Fees

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 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. TDRs are considered impaired and are individually evaluated for impairment. TDRs 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. In March 2020, the Company announced loan modification programs to support and provide relief for its borrowers during the novel coronavirus of 2019 ("COVID-19") pandemic. The Company has followed the loan modification criteria within the Coronavirus Aid, Relief, and Economic Security Act of 2020 ("CARES Act"), which was signed into law on March 27, 2020 and interagency guidance from the federal banking agencies when determining if a borrower's modification is subject to a TDR classification. If it is determined that the modification does not meet the criteria under the CARES Act or interagency guidance to be excluded from TDR classification, the Company evaluates the loan modifications under its existing TDR framework. Loans subject to forbearance under the COVID-19 loan modification program are not reported as past due or placed on non-accrual status during the forbearance time period, and interest income continues to be recognized over the contractual life of the loans.

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 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-impaired loans 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.  When determining the appropriate historical loss and qualitative factors, management took into consideration the impact of the COVID-19 pandemic on such factors as the national and state unemployment rates and related trends, the amount of and timing of financial assistance provided by the government, consumer spending levels and trends, industries significantly impacted by the COVID-19 pandemic, and the Company's COVID-19 loan modification program. The appropriateness of the allowance for loan losses is estimated based upon these factors and trends identified by management at the time the consolidated financial statements are prepared.

A loan is considered impaired when it is probable that the Company 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 estimated net realizable value 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 and furniture and equipment - three to seven 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 undiscounted 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, 2020 or 2019 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. 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 values 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 in a business combination exceeds the estimated fair value of the net identified tangible and intangible assets acquired and liabilities assumed.  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. For purposes of goodwill impairment testing, the services offered through the Bank and its subsidiary are managed as one strategic unit and represent the Company's only reporting unit.

The annual goodwill impairment test begins with a qualitative assessment of whether it is "more likely than not" that the reporting unit's fair value is less than its carrying amount. If an entity concludes that it is not "more likely than not" that the fair value of a reporting unit is less than its carrying amount, it need not perform a two-step impairment test. If the Company's qualitative assessment concluded that it is "more likely than not" that the fair value of its reporting unit is less than its carrying amount, it must perform the two-step impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized, if any. The first step of the goodwill impairment test compares the estimated fair value of the reporting unit with its carrying amount, or the book value, including goodwill. If the estimated fair value of the reporting unit equals or exceeds its book value, goodwill is considered not impaired, and the second step of the impairment test is unnecessary.

The second step, if necessary, measures the amount of goodwill impairment loss to be recognized. The reporting unit must determine fair value for all assets and liabilities, excluding goodwill. The net of the assigned fair value of assets and liabilities is then compared to the book value of the reporting unit, and any excess book value becomes the implied fair value of goodwill. If the carrying amount of the goodwill exceeds the newly calculated implied fair value of goodwill, an impairment loss is recognized in the amount required to write-down the goodwill to the implied fair value.

Management's qualitative assessment takes into consideration macroeconomic conditions, industry and market considerations, cost or margin factors, financial performance and the share price of the Company's common stock. The Company performed its fiscal year 2020 goodwill impairment test during the quarter ended June 30, 2020 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, 2020 and the step one test concluded that the reporting unit's fair value was more than its recorded value and, therefore, step two of the analysis was not necessary. Accordingly, the recorded value of goodwill as of May 31, 2020 was not impaired.

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 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. Any change in these indicators 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, 2020, management believes that there were no events or changes in the circumstances since May 31, 2020 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. If adverse economic conditions or the recent decrease in the Company's stock price and market capitalization as a result of the COVID-19 pandemic were deemed to be other than temporary, it may significantly affect the fair value of the Company's goodwill and may trigger impairment charges. Any impairment charge could have a material adverse effect on the Company's results of operation and financial condition.

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. Servicing rights are capitalized at estimated fair value when acquired through the origination of loans that are subsequently sold with the servicing rights retained. Servicing rights are amortized to servicing income on loans sold approximately in proportion to and over the period of estimated net servicing income.  The value of servicing rights 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 servicing rights must be stratified by one or more predominant risk characteristics of the underlying loans.  The Company stratifies its capitalized servicing rights 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 servicing rights 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 and various state income tax returns.  The Bank provides for income taxes separately and remits to (receives from) Timberland Bancorp amounts currently due (receivable).

Deferred 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, 2016.

ESOP

The Bank sponsors a leveraged ESOP; however, all ESOP debt was fully repaid during the year ended September 30, 2019. The debt of the ESOP was payable to Timberland Bancorp, was recorded as other borrowed funds of the Bank, and was eliminated in the consolidated financial statements. The shares of the Company's common stock pledged as collateral for the ESOP's debt were reported as unearned shares issued to the ESOP in the consolidated financial statements. As shares were released from collateral, compensation expense was recorded equal to the average market price of the shares for the period, and the shares became available for net income per common share calculations.  Dividends paid on unallocated shares reduced 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.  Stock option forfeitures are accounted for as they occur.

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 the Company's common stock during the period. Common stock equivalents arise from the assumed conversion of outstanding stock options.  Shares owned by the Bank’s ESOP that have not been allocated are not considered to be outstanding for the purpose of computing basic and diluted net income per common share.

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.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers, which created FASB Accounting Standards Codification ("ASC") Topic 606 ("ASC 606"). The core principle of ASC 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASC 606 was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company adopted ASC 606 on October 1, 2018 using the modified retrospective approach. Therefore, the comparative information has not been adjusted and continues to be reported under the superseded ASC 605. There was no cumulative effect adjustment as of October 1, 2018, and there were no material changes to the timing or amount of revenue recognized for the year ended September 30, 2019; however, additional disclosures were incorporated in the footnotes upon adoption. The majority of the Company's revenue is comprised of interest income from financial assets, which is explicitly excluded from the scope of ASC 606. The Company elected to apply the practical expedient pursuant to ASC 606 and therefore does not disclose information about remaining performance obligations that have an original expected term of one year or less and allows the Company to expense costs related to obtaining a contract as incurred when the amortization period would have been one year or less. See Note 24 for additional information.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 generally requires equity investments - except those accounted for under the equity method of accounting or those that result in consolidation of the investee - to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. ASU 2016-01 is intended to simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. ASU 2016-01 also eliminates certain disclosures related to the fair value of financial instruments and requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. ASU 2016-01 was effective for fiscal years beginning after December 15, 2017, including interim periods

within those fiscal years. The Company adopted ASU 2016-01 on October 1, 2018. As required by ASU 2016-01, on October 1, 2018 the Company recorded a one-time cumulative effect adjustment of $63,000 representing net unrealized losses on equity securities (mutual funds) between accumulated other comprehensive loss and retained earnings on the accompanying consolidated balance sheet. Additionally, the fair values of financial instruments for disclosure purposes were computed using an exit price notion and deposits with no stated maturity are no longer included in the fair value disclosures in Note 22.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which created FASB ASC Topic 842 ("ASC 842") and 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 ASC 842 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 generally on a 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. ASC 842 also changes disclosure requirements related to leasing activities and requires certain qualitative disclosures along with specific quantitative disclosures. ASC 842 also provides an optional transition method for adoption, under which an entity initially applies ASC 842 at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity's reporting for the comparative periods presented in the financial statements in which it adopts ASC 842 will continue to be in accordance with current GAAP. ASC 842 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early application of ASC 842 is permitted. The Company adopted the provisions of ASC 842 effective October 1, 2019 utilizing the optional transition method and will not restate comparative periods. The Company also elected the package of practical expedients permitted under ASC 842's transition guidance, which allows the Company to carryforward its historical lease classifications and its assessment as to whether a contract is or contains a lease. The Company also elected to not recognize lease assets and lease liabilities for leases with an initial term of 12 months or less. As a result of adopting ASC 842, ROU assets and operating lease liabilities increased by $2.89 million on October 1, 2019.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses, as amended by ASU 2018-19, ASU 2019-04 and ASU 2019-05. This ASU replaces the existing incurred losses methodology with a current expected 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 as a reduction of the carrying amount. ASU 2016-13 also changes the accounting for purchased credit-impaired debt securities and loans. ASU 2016-13 retains many of the current disclosure requirements in GAAP and expands certain disclosure requirements. ASU 2016-13 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Upon adoption, the Company expects a change in the processes and procedures to calculate the allowance for loan losses, including changes in the assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. In addition, the current policy for other-than-temporary impairment on investment securities available for sale will be replaced with an allowance approach. The Company is reviewing the requirements of ASU 2016-13 and has begun developing and implementing processes and procedures to ensure it is fully compliant with the amendments at the adoption date. At this time, the Company anticipates the allowance for loan losses will increase as a result of the implementation of this ASU; however, until its evaluation is complete, the magnitude of the increase will be unknown.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment. This ASU simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value of its assets and liabilities (including unrecognized assets and liabilities) at the impairment testing date following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by

which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax

deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. ASU 2017-04 is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2022.

The adoption ASU 2017-04 is not expected to a have a material impact on the Company's future consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This ASU shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. This ASU was effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018. The Company adopted ASU 2017-08 effective October 1, 2019 and it did not have a material impact on the Company's consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU was issued to provide clarity as to when to apply modification accounting when there is a change in the terms or conditions of a share-based payment award. According to the ASU, an entity should account for the effects of a modification unless the fair value, vesting conditions, and balance sheet classification of the award are the same after the modification as compared to the original award prior to modification. ASU 2017-09 was effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The Company adopted ASU 2017-09 effective October 1, 2018 and it did not have a material impact on the Company's consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This ASU was issued to expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. Previously, these awards were recorded at the fair value of consideration received or the fair value of the equity instruments issued and were measured at the earlier of the commitment date or the date performance was completed. The amendments in this ASU require nonemployee share-based payment awards to be measured at the grant-date fair value of the equity instrument. ASU 2018-07 was effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018. The Company adopted ASU 2018-07 effective October 1, 2019 and it did not have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements. The following disclosure requirements were removed from ASC Topic 820, Fair Value Measurement: (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; and (3) the valuation process for Level 3 fair value measurements. This ASU clarifies that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. This ASU adds the following disclosure requirements for Level 3 measurements: (1) changes in unrealized gains and losses for the period included in other comprehensive income for the recurring Level 3 fair value measurements held at the end of the reporting period, and (2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. ASU 2018-13 was effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted ASU 2018-13 effective October 1, 2020 and it is not expected to have a material impact on the Company's future consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40), Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this ASU broaden the scope of ASC Subtopic 350-40 to include costs incurred to implement a hosting arrangement that is a service contract. The amendments align the requirements for capitalizing implementation costs incurred

in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The costs are capitalized or expensed depending on the nature of the costs and the project stage during which they are incurred, consistent with the accounting for internal-use software costs. The amendments in this ASU result in consistent capitalization of implementation costs of a hosting arrangement that is a service contract and implementation costs incurred 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 in this ASU. ASU 2018-15 was effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company adopted ASU 2018-15 effective October 1, 2020 and it is not expected to have a material impact on the Company's future consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidelines. ASU 2019-12 is effective for fiscal years beginning after December 15, 2021,

including interim periods within fiscal years. The adoption of ASU 2019-12 is not expected to have a material impact on the Company's future consolidated financial statements.

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU applies to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate ("LIBOR") or other rate references expected to be discontinued because of reference rate reform. The ASU permits an entity to make necessary modifications to eligible contracts or transactions without requiring contract remeasurement or reassessment of a previous accounting determination. This ASU is effective for all entities as of March 12, 2020 through December 31, 2022. The Company has not adopted ASU 2020-04 as of September 30, 2020. The adoption of ASU 2020-04 is not expected to have a material impact on the Company's future consolidated financial statements.

On March 22, 2020, federal banking regulators issued an interagency statement that included guidance on their approach for the accounting of loan modifications in light of the economic impact of the COVID-19 pandemic. The guidance interprets current accounting standards and indicates that a lender can conclude that a borrower is not experiencing financial difficulty if short-term modifications are made in response to COVID-19, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant related to the loans in which the borrower is less than 30 days past due on its contractual payments at the time a modification is implemented. The agencies confirmed in working with the staff of the FASB that short-term modification made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not troubled debt restructurings.
