BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of Business:  Banner Corporation (Banner or the Company) is a bank holding company incorporated in the State of Washington.  The Company is primarily engaged in the business of planning, directing and coordinating the business activities of its wholly-owned subsidiary, Banner Bank (the Bank). The Bank is a Washington-chartered commercial bank that conducts business from its headquarters in Walla Walla, Washington and its 135 branch offices located in Washington, Oregon, California and Idaho. The Bank also has 13 loan production offices located in Washington, Oregon, California, Idaho and Utah.  Banner is subject to regulation by the Board of Governors of the Federal Reserve System (the Federal Reserve Board).  The Bank is subject to regulation by the Washington State Department of Financial Institutions, Division of Banks (the DFI) and the Federal Deposit Insurance Corporation (the FDIC).

Basis of Presentation and Principles of Consolidation:  The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary.  All material intercompany transactions, profits and balances have been eliminated. The consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) and under the rules and regulations of the U.S. Securities and Exchange Commission (the SEC). At December 31, 2024, the Company had five wholly-owned subsidiary grantor trusts (the Trusts), each of which issued trust preferred securities (TPS) and common securities. The Trusts are not consolidated in the Company’s consolidated financial statements.

Operating Segments:  The Company’s operations are managed, and financial performance is evaluated, by our chief operating decision maker on a Company-wide basis.  The Bank’s primary business is that of a traditional banking institution, gathering deposits and originating loans for portfolio in its primary market areas.  The Bank offers a wide variety of deposit products to its consumer and commercial clients.  Lending activities include the origination of real estate, commercial/agriculture business and consumer loans.  The performance of the Company is reviewed monthly by the Company’s executive management and Board of Directors.  As resource allocation and performance decisions are not made based on discrete financial information of individual lines of business, the Company considers its current business and operations as a single reportable operating segment.

Subsequent Events: The Company has evaluated events and transactions subsequent to December 31, 2024 through the date that the consolidated financial statements were issued for potential recognition or disclosure.

Cash and Cash Equivalents: Cash and cash equivalents include cash and due from banks and temporary investments which are federal funds sold and interest bearing balances due from other banks. Cash and cash equivalents generally have maturities of three months or less at the date of purchase.

Business Combinations: Business combinations are accounted for using the acquisition method of accounting and, accordingly, assets acquired and liabilities assumed, both tangible and intangible, and consideration exchanged are recorded at acquisition date fair values. The excess purchase consideration over fair value of net assets acquired is recorded as goodwill. In the event that the fair value of net assets acquired exceeds the purchase price, including fair value of liabilities assumed, a bargain purchase gain is recorded on that acquisition. Expenses incurred in connection with a business combination are expensed as incurred, except for those items permitted to be capitalized. Changes in deferred tax asset valuation allowances related to acquired tax uncertainties are recognized in net income after the measurement period.

Use of Estimates:  In the opinion of Management, the accompanying Consolidated Statements of Financial Condition and related Consolidated Statements of Operations, Comprehensive Income (Loss), Changes in Shareholders’ Equity and Cash Flows reflect all adjustments (which include reclassification and normal recurring adjustments) that are necessary for a fair presentation in conformity with GAAP.  The preparation of financial statements in conformity with GAAP requires Management to make estimates and assumptions that affect amounts reported in the financial statements.

Various elements of the Company’s accounting policies, by their nature, are inherently subject to estimation techniques, valuation assumptions and other subjective assessments.  Management has identified several accounting policies that, due to the judgments, estimates and assumptions inherent in those policies, are critical to an understanding of Banner’s Consolidated Financial Statements.  These policies relate to (i) determination of the provision and allowance for credit losses, (ii) the valuation of financial assets and liabilities recorded at fair value, and (iii) the valuation or recognition of deferred tax assets and liabilities. Management believes that the judgments, estimates and assumptions used in the preparation of the consolidated financial statements are appropriate based on the factual circumstances at the time.  However, given the sensitivity of the Consolidated Financial Statements to these critical accounting estimates, the use of judgments, estimates and assumptions could result in material differences in the Company’s results of operations or financial condition.  Further, subsequent changes in economic or market conditions could have a material impact on these estimates and the Company’s financial condition and operating results in future periods.
Securities: Debt securities are classified as held-to-maturity when the Company has the ability and positive intent to hold them to maturity.  Debt securities classified as available-for-sale are available for future liquidity requirements and may be sold prior to maturity.  Debt securities classified as trading are also available for future liquidity requirements and may be sold prior to maturity.  Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities.  Debt securities classified as held-to-maturity are carried at cost, net of the allowance for credit losses - securities, adjusted for amortization of premiums to the earliest callable date and accretion of discounts to maturity.  Debt securities classified as available-for-sale are measured at fair value.  Unrealized holding gains and losses on debt securities classified as available-for-sale are excluded from earnings and are reported net of tax as accumulated other comprehensive income (AOCI), a component of shareholders’ equity, until realized.  Debt securities classified as trading are also measured at fair value.  Unrealized holding gains and losses on securities classified as trading are included in earnings.  Realized gains and losses on sale are computed on the specific identification method and are included in earnings on the trade date sold. Equity securities are measured at fair value with changes in the fair value recognized through net income.

Allowance for Credit Losses - Securities: Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type. The Company’s held-to maturity portfolio contains mortgage-backed securities issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses. The Company’s held-to-maturity portfolio also contains municipal bonds that are typically rated by major rating agencies as Aa or better. The Company has never incurred a loss on a municipal bond, therefore the expectation of credit losses on these securities is insignificant. The Company uses industry historical credit loss information adjusted for current conditions to establish the allowance for credit losses on the municipal bond portfolio. The expected credit losses on these bonds are similar to Banner’s commercial business loan portfolio. Therefore, the Company uses the commercial business loan portfolio loss rates to establish the allowance for credit losses on the collateralized bonds and its own loss history to establish a loss rate on bonds that are not collateralized.

For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If the Company intends to sell the security or it is more likely than not that the Company will be required to sell the security before recovering its cost basis, the entire impairment loss would be recognized in earnings.  If the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, Management considers the extent to which fair value is less than amortized costs, any changes to the rating of the security by a rating agency and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security.  Projected cash flows are discounted by the current effective interest rate.  If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. The remaining impairment related to all other factors, the difference between the present value of the cash flows expected to be collected and fair value, is recognized in AOCI.

Changes in the allowance for credit losses are recorded as provision (recapture) for credit losses. Losses are charged against the allowance when Management believes the non-collectability of an available-for-sale or held-to-maturity security is confirmed or when either of the criteria regarding intent or requirement to sell is met.

Investment in FHLB Stock: FHLB stock does not have a readily determinable fair value. The Bank’s investment in FHLB stock is carried at cost or par value ($100 per share) and evaluated for impairment based on the Bank’s expectations of the ultimate recoverability of the stock’s par value. Ownership of FHLB stock is restricted to the FHLB and member institutions and can only be purchased and redeemed at par, therefore there has been no observable changes in market prices. As a member of the FHLB system, the Bank is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding FHLB advances.

Management periodically evaluates FHLB stock for impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the client base of the FHLB, and (4) the liquidity position of the FHLB. The Company has determined there is no impairment on the FHLB stock investment as of December 31, 2024 and 2023.

Loans Receivable:  The Bank originates one- to four-family residential loans for both portfolio investment and sale in the secondary market.  The Bank also originates construction and land development, multifamily mortgage, commercial real estate, commercial business, agricultural and consumer loans for portfolio investment.  Loans receivable not designated as held for sale are recorded at amortized cost, net of the allowance for credit losses. Amortized cost is the principal amount outstanding, net of deferred fees, discounts and premiums.  Accrued interest on loans is reported in accrued interest receivable on the Consolidated Statements of Financial Condition. Premiums, discounts and deferred loan fees are amortized to maturity using the level-yield methodology.
Loans Held for Sale: One- to four-family residential loans originated with the intent to be sold in the secondary market are considered held for sale. One- to four-family residential loans under best effort delivery commitments are carried at the lower of aggregate cost or estimated market value. One- to four-family residential loans expected to be delivered under mandatory commitments are carried at fair value to match changes in the value of the loans with the value of the related economic hedges on the loans. Fair values for residential mortgage loans held for sale are determined by comparing actual loan rates to current secondary market prices for similar loans. Net unrealized losses on loans held for sale that are carried at lower of cost or market are recognized through the valuation allowance as charges to income.  Non-refundable fees and direct loan origination costs related to loans held for sale carried at the lower of cost or market are recognized as part of the cost basis of the loan. Gains and losses on sales of loans held for sale are determined using the aggregate method and are recorded in the mortgage banking operations component of non-interest income. Non-refundable fees and direct loan origination costs related to loans held for sale carried at the lower of cost or market are recognized as part of the cost basis of the loan.

Loans Acquired in Business Combinations: Loans acquired in business combinations are recorded at their fair value at the acquisition date. Establishing the fair value of acquired loans involves a significant amount of judgment, including determining the credit discount based upon historical data adjusted for current economic conditions and other factors. If any of these assumptions are inaccurate, actual credit losses could vary significantly from the credit discount used to calculate the fair value of the acquired loans. Acquired loans are evaluated upon acquisition and classified as either purchased credit-deteriorated or purchased non-credit-deteriorated. Purchased credit-deteriorated (PCD) loans have experienced more than insignificant credit deterioration since origination. For PCD loans, an allowance for credit losses is determined at the acquisition date using the same methodology as other loans held for investment. The initial allowance for credit losses, determined on a collective basis, is allocated to individual loans. A loan’s fair value is grossed up for the allowance for credit losses and becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through a provision (recapture) for credit losses.

For purchased non-credit-deteriorated 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 loan. While credit discounts are included in the determination of the fair value for non-credit-deteriorated loans, since these discounts are expected to be accreted over the life of the loans, they cannot be used to offset the allowance for credit losses that must be recorded at the acquisition date. As a result, an allowance for credit losses is determined at the acquisition date using the same methodology as other loans held for investment and is recognized as a provision for credit losses. Any subsequent deterioration (improvement) in credit quality is recognized by recording a provision (recapture) for credit losses.

Income Recognition on Nonaccrual Loans and Securities:  Interest on loans and securities is accrued as earned unless Management doubts the collectability of the asset or the unpaid interest.  Interest accruals on loans are generally discontinued when loans become 90 days past due for payment of interest or principal and the loans are then placed on nonaccrual status.  All previously accrued but uncollected interest is deducted from interest income upon transfer to nonaccrual status.  For any future payments collected, interest income is recognized only upon Management’s assessment that there is a strong likelihood that the full amount of a loan will be repaid or recovered. Management’s assessment of the likelihood of full repayment involves judgment, including determining the fair value of the underlying collateral which can be impacted by the economic environment.  A loan may be put on nonaccrual status sooner than this policy would dictate if, in Management’s judgment, the amounts owed, principal or interest may be uncollectable.  While less common, similar interest reversal and nonaccrual treatment is applied to investment securities if their ultimate collectability becomes questionable.

Provision and Allowance for Credit Losses - Loans:  The methodology for determining the allowance for credit losses - loans is considered a critical accounting estimate by Management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the economic environment that could result in changes to the amount of the recorded allowance for credit losses - loans. Among the material estimates required to establish the allowance for credit losses - loans are: a reasonable and supportable forecast; a reasonable and supportable forecast period and reversion period; value of collateral; strength of guarantors; the amount and timing of future cash flows for loans individually evaluated; and determination of the qualitative loss factors. All of these estimates are susceptible to significant change. The allowance for credit losses - loans is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. The Company has elected to exclude accrued interest receivable from the amortized cost basis in their estimate of the allowance for credit losses - loans. The provision for credit losses reflects the amount required to maintain the allowance for credit losses - loans at an appropriate level based upon Management’s evaluation of the adequacy of collective and individual loss reserves. The Company has established systematic methodologies for the determination of the adequacy of the Company’s allowance for credit losses - loans. The methodologies are set forth in a formal policy and take into consideration the need for a valuation allowance for loans evaluated on a collective (pool) basis which have similar risk characteristics as well as allowances that are tied to individual loans that do not share risk characteristics.

The Company increases its allowance for credit losses - loans by charging the provision for credit losses. Losses related to specific assets are applied as a reduction of the carrying value of the assets and charged against the allowance for credit loss reserve when Management believes the uncollectibility of a loan balance is confirmed. Recoveries on previously charged off loans are credited to the allowance for credit losses - loans.
Management estimates the allowance for credit losses - loans using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The allowance for credit losses - loans is maintained at a level sufficient to provide for expected credit losses over the life of the loan based on evaluating historical credit loss experience and making adjustments to historical loss information for differences in the specific risk characteristics in the current loan portfolio.  These factors include, among others, changes in the size and composition of the loan portfolio, differences in underwriting standards, delinquency rates, actual loss experience and current economic conditions.

The allowance for credit losses - loans is measured on a collective (pool) basis when similar risk characteristics exist. In estimating the component of the allowance for credit losses for loans that share common risk characteristics, loans are pooled based on loan type and areas of risk concentration. For loans evaluated collectively, the allowance for credit losses is calculated using life of loan historical losses adjusted for economic forecasts and current conditions.

For commercial real estate, multifamily real estate, construction and land and land development, commercial business and agricultural loans with risk rating segmentation, historical credit loss assumptions are estimated using a model that categorizes loan pools based on loan type and risk rating. For one- to four- family residential loans, consumer loans, home equity lines of credit, small business loans, and small balance commercial real estate loans, historical credit loss assumptions are estimated using a model that categorizes loan pools based on loan type and delinquency status. These models calculate an expected life-of-loan loss percentage for each loan category by calculating the probability of default, based on the migration of loans from performing to loss by risk rating or delinquency categories using historical life-of-loan analysis and the severity of loss, based on the aggregate net lifetime losses incurred for each loan pool. For credit cards, historical credit loss assumptions are estimated using a model that calculates an expected life-of-loan loss percentage for each loan category by considering the historical cumulative losses based on the aggregate net lifetime losses incurred for each loan pool.

For loans evaluated collectively, Management uses economic indicators to adjust the historical loss rates so that they better reflect Management’s expectations of future conditions over the remaining lives of the loans in the portfolio based on reasonable and supportable forecasts. These economic indicators are selected based on correlation to the Company’s historical credit loss experience and are evaluated for each loan category. The economic indicators evaluated include the unemployment rate, gross domestic product, real estate price indices and growth, industrial employment, corporate profits, the household consumer debt service ratio, the household mortgage debt service ratio, and single family median home price growth. Management considers various economic scenarios and forecasts when evaluating the economic indicators and weighs the probability of various scenarios to arrive at the forecast that most reflects Management’s expectations of future conditions. The allowance for credit losses is then adjusted for the period in which those forecasts are considered to be reasonable and supportable. To the extent the lives of the loans in the portfolio extend beyond the period for which a reasonable and supportable forecast can be made, the adjustments discontinue to be applied so that the model reverts back to the historical loss rates using a straight-line reversion method. Management selected a reasonable and supportable forecast period of 12 months with a reversion period of 12 months. Both the reasonable and supportable forecast period and the reversion period are periodically reviewed by Management.

Further, for loans evaluated collectively, Management also considers qualitative and environmental factors for each loan category to adjust for differences between the historical periods used to calculate historical loss rates and expected conditions over the remaining lives of the loans in the portfolio. In determining the aggregate adjustment needed, Management considers the financial condition of the borrowers, the nature and volume of the loans, the remaining terms and the extent of prepayments on the loans, the volume and severity of past due and classified loans as well as the value of the underlying collateral on loans in which the collateral dependent practical expedient has not been used. Management also considers the Company’s lending policies, the quality of the Company’s credit review system, the quality of the Company’s management and lending staff, and the regulatory and economic environments in the areas in which the Company’s lending activities are concentrated.

Loans that do not share risk characteristics with other loans in the portfolio are individually evaluated for impairment and are not included in the collective evaluation.  Factors involved in determining whether a loan should be individually evaluated include, but are not limited to, the financial condition of the borrower and the value of the underlying collateral.  Expected credit losses for loans evaluated individually are primarily measured based on the fair market value of the collateral as of the reporting date, less estimated selling costs, as applicable. Under certain circumstances, the Bank may use observable market value of collateral or the present value of the expected future cash flows discounted at the loan’s original effective interest rate. As a practical expedient, the Bank measures the expected credit loss for a loan using the fair value of the collateral, if repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the Bank’s assessment as of the reporting date.

In both cases, if the fair value of the collateral is less than the amortized cost basis of the loan, the Bank will recognize an allowance as the difference between the fair value of the collateral, less costs to sell (if applicable) at the reporting date and the amortized cost basis of the loan. If the fair value of the collateral exceeds the amortized cost basis of the loan, any expected recovery added to the amortized cost basis will be limited to the amount previously charged-off. Subsequent changes in the expected credit losses for loans evaluated individually are included within the provision for credit losses in the same manner in which the expected credit loss initially was recognized or as a reduction in the provision that would otherwise be reported.
Loan Origination and Commitment Fees:  Loan origination fees, net of certain specifically defined direct loan origination costs, are deferred and recognized as an adjustment of the loans’ interest yield using the level-yield method over the contractual term of each loan adjusted for actual loan prepayment experience.  Loan commitment fees are deferred until the expiration of the commitment period unless Management believes there is a remote likelihood that the underlying commitment will be exercised, in which case the fees are amortized to fee income using the straight-line method over the commitment period.  If a loan commitment is exercised, the deferred commitment fee is accounted for in the same manner as a loan origination fee.  Deferred commitment fees associated with expired commitments are recognized as fee income.

Allowance for Credit Losses - Unfunded Loan Commitments: An allowance for credit losses - unfunded loan commitments is maintained at a level that, in the opinion of Management, is adequate to absorb expected credit losses associated with the contractual life of the Bank’s commitments to lend funds under existing agreements such as letters or lines of credit. The Bank uses a methodology for determining the allowance for credit losses - unfunded loan commitments that applies the same segmentation and loss rate to each pool as the funded exposure adjusted for probability of funding. Draws on unfunded loan commitments that are considered uncollectible at the time funds are advanced are charged to the allowance for credit losses on off-balance sheet exposures. Changes in the allowance for credit losses - unfunded loan commitments are recognized as provision for (or recapture of) credit loss expense and added to the allowance for credit losses - unfunded loan commitments, which is included in other liabilities in the Consolidated Statements of Financial Condition.

Real Estate Owned: Property acquired by foreclosure or deed in-lieu-of foreclosure is recorded at the estimated fair value of the property, less expected selling costs.  Development and improvement costs relating to the property may be capitalized, while other holding costs are expensed.  The carrying value of the property is periodically evaluated by Management and, if necessary, allowances are established to reduce the carrying value to net realizable value.  Gains or losses at the time the property is sold are charged or credited to operations in the period in which they are realized.  The amounts the Bank will ultimately recover from real estate held for sale may differ substantially from the carrying value of the assets because of market factors beyond the Bank’s control or because of changes in the Bank’s strategies for recovering the investment.

Property and Equipment:  Property and equipment is carried at cost less accumulated depreciation. Depreciation is based upon the straight-line method applied to individual assets and groups of assets acquired in the same year over the lesser of their estimated useful lives or the related lease terms of the assets, which are as follows:
Buildings and leased improvements
10–39 years
Furniture and equipment
3–10 years

Routine maintenance, repairs and replacement costs are expensed as incurred.  Expenditures which significantly increase values or extend useful lives are capitalized.  The Company reviews buildings, leasehold improvements and equipment for impairment whenever events or changes in circumstances indicate that the undiscounted cash flows for the property are less than its carrying value.  If identified, an impairment loss is recognized through a charge to earnings based on the fair value of the property.

Property is classified as held for sale when the Company commits to a plan to sell the property and is actively marketing the property for sale. Held for sale property is recorded at the lower of the estimated fair value of the property, less expected selling costs, or the book value at the date the property is transferred to held for sale. Depreciation is not recorded on held for sale property.

Leases: The Company leases retail, office and storage space, and equipment under operating leases. Most leases require the Company to pay real estate taxes, maintenance, insurance and other similar costs in addition to the base rent. Certain leases also contain lease incentives, such as tenant improvement allowances and rent abatement. Variable lease payments are recognized as lease expense as they are incurred. We record an operating lease right of use (ROU) asset and an operating lease liability (lease liability) for operating leases with a lease term greater than 12 months.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Accordingly, ROU assets are reduced by tenant improvement allowances from landlords plus any prepaid rent. We do not separate lease and non-lease components of contracts. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. Many of our leases contain various provisions for increases in rental rates, based either on changes in the published Consumer Price Index or a predetermined escalation schedule which are factored into our determination of lease payments when appropriate. Substantially, all the leases provide the Company with the option to extend the lease term one or more times following expiration of the initial term. The ROU asset and lease liability terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.
Goodwill: Goodwill represents the excess of the purchase consideration paid over the fair value of the assets acquired, net of the fair values of liabilities assumed in a business combination and is not amortized but is reviewed annually or more frequently as current circumstances and conditions warrant, for impairment. The Company completes its annual review of goodwill as of December 31. An assessment of qualitative factors is completed to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The qualitative assessment involves judgment by Management on determining whether there have been any triggering events that have occurred which would indicate potential impairment. If the qualitative analysis concludes that further analysis is required, then a quantitative impairment test would be completed. The quantitative goodwill impairment test is used to identify the existence of impairment and the amount of impairment loss and compares the reporting unit’s estimated fair values, including goodwill, to its carrying amount. If the fair value exceeds the carrying amount, then goodwill is not considered impaired. If the carrying amount exceeds its fair value, an impairment loss would be recognized equal to the amount of excess, limited to the amount of total goodwill allocated to the reporting unit. The impairment loss would be recognized as a charge to earnings. The disposal of a portion of a reporting unit that meets the definition of a business requires goodwill to be allocated for purposes of determining the gain or loss on disposal.

Other Intangible Assets:  Other intangible assets consist primarily of core deposit intangibles (CDI) which are amounts recorded in business combinations or deposit purchase transactions related to the value of transaction-related deposits and the value of the client relationships associated with the deposits.  CDI is being amortized on an accelerated basis over a weighted average estimated useful life of eight to 10 years.  These assets are reviewed at least annually for events or circumstances that could impact their recoverability.  These events could include loss of the underlying core deposits, increased competition or adverse changes in the economy.  To the extent other identifiable intangible assets are deemed unrecoverable, impairment losses are recorded in other non-interest expense to reduce the carrying amount of the assets.

Mortgage and Small Business Administration (SBA) Servicing Rights: Servicing assets are recognized as separate assets when rights are acquired through purchase or sale of loans.  Generally, purchased servicing rights are capitalized at the cost to acquire the rights.  For sales of mortgage and SBA loans, the fair value of the servicing right is estimated and capitalized.  Fair values are estimated based on an independent dealer analysis of discounted cash flows. Capitalized mortgage servicing rights are reported in other assets and are amortized into mortgage banking operations in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Capitalized SBA servicing rights are reported in other assets and are carried at fair value. Changes in the fair value of SBA servicing rights are recognized into miscellaneous non-interest income.

Mortgage servicing assets are evaluated for impairment based upon the fair value of the rights as compared to amortized cost.  Impairment is determined by stratifying rights into tranches based on predominant risk characteristics for the underlying loans, such as interest rate, balance outstanding, loan type, age and remaining term, and investor type.  Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranche.  If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income.

Servicing fee income is recorded for fees earned for servicing loans. Servicing fee income is reflected in mortgage banking operations for mortgage servicing rights and in miscellaneous non-interest income for SBA servicing rights on the Consolidated Statements of Operations.  The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned.  The amortization of mortgage servicing rights is netted against loan servicing fee income.

Bank-Owned Life Insurance:  The Bank has purchased, or acquired through mergers, life insurance policies in connection with the implementation of certain executive supplemental income, salary continuation and deferred compensation retirement plans.  These policies provide protection against the adverse financial effects that could result from the death of a key employee and provide tax-exempt income to offset expenses associated with the plans.  It is the Bank’s intent to hold these policies as a long-term investment; however, there may be an income tax impact if the Bank chooses to surrender certain policies.  Although the lives of individual, current or former management-level employees are insured, the Bank is the respective owner and sole or partial beneficiary. BOLI is carried at the cash surrender value (CSV) of the underlying insurance contract. Changes in the CSV and any death benefits received in excess of the CSV are recognized as non-interest income.

Derivative Instruments:  Derivatives include “off-balance-sheet” financial products, the value of which is dependent on the value of underlying financial assets, such as stock, bonds, foreign currency, or a reference rate or index.  Such derivatives include “forwards,” “futures,” “options” or “swaps.”  The Bank used an interest rate swap program which involves the receipt of fixed-rate amounts from a counterparty in exchange for variable-rate payments over the life of the agreements without exchange of the underlying notional amount. Such derivatives were used to hedge the variable cash flows associated with existing variable-rate assets. These interest rate swaps qualified as cash flow hedging instruments so gains and losses were recorded in AOCI to the extent the hedge was effective. Gains and losses on the interest rate swaps were reclassified from AOCI to earnings in the period the hedged transaction affected earnings and were included in interest income. Amounts reported in AOCI related to derivatives were reclassified to interest income as interest payments were received on the Company’s variable-rate assets. The related cash flows were recognized as cash flows from operating activities on the Consolidated Statement of Cash Flows. These cash flow hedges matured in 2024.

The Bank offers an interest rate swap program for commercial loan clients that provides the client with a variable-rate loan and enters into an interest rate swap allowing them to effectively fix their loan interest rates.  These client swaps are matched with third party swaps with qualified broker/dealer or banks to offset the risk.  The fair value adjustments for these swaps are recorded in either other assets or other liabilities, as appropriate.
Further, as a part of its mortgage banking activities, the Company issues “rate lock” commitments to one- to four-family loan borrowers and obtains offsetting “best efforts” delivery commitments from purchasers of loans. The Company uses forward contracts for the sale of mortgage-backed securities and mandatory delivery commitments for the sale of loans to hedge one- to four-family loan “rate lock” commitments and one- to four-family residential loans held for sale.  The commitments to originate mortgage loans held for sale and the related delivery contracts are considered derivatives.  The Company recognizes all derivatives as either assets or liabilities in the balance sheet and requires measurement of those instruments at fair value through adjustments to current earnings.  None of these residential mortgage loan related derivatives are designated as hedging instruments for accounting purposes.  Rather, they are accounted for as free-standing derivatives, or economic hedges, and the Company reports changes in fair values of its derivatives in current period net income.  The fair values for these instruments, which generally change as a result of changes in the level of market interest rates, are estimated based on dealer quotes and secondary market sources.  Assumptions used include rate assumptions based on historical information, current mortgage interest rates, the stage of completion of the underlying application and underwriting process, the time remaining until the expiration of the derivative loan commitment, and the expected net future cash flows related to the associated servicing of the loan.

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 Bank, (2) the transferee has the right to pledge or exchange the transferred assets beyond a trivial benefit, and (3) the Bank 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 income tax return including all of its wholly-owned subsidiaries on a calendar year basis.  Income taxes are accounted for using the asset and liability method.  Under this method, a deferred tax asset or liability is determined based on the enacted tax rates which are expected to be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company’s income tax returns.  The effect on deferred taxes of a change in tax rates is recognized in income in the period of change. A valuation allowance is recognized as a reduction to deferred tax assets when Management determines it is more likely than not that deferred tax assets will not be available to offset future income tax liabilities.

Accounting standards for income taxes prescribe a recognition threshold and measurement process for financial statement recognition and measurement of uncertain tax positions taken or expected to be taken in a tax return, and provides guidance on the de-recognition of previously recorded benefits and their classification, as well as the proper recording of interest and penalties, accounting in interim periods, disclosures and transition.  The Company periodically reviews its income tax positions based on tax laws and regulations and financial reporting considerations, and records adjustments as appropriate.  This review takes into consideration the status of current taxing authorities’ examinations of the Company’s tax returns, recent positions taken by the taxing authorities on similar transactions, if any, and the overall tax environment.

Stock-Based Compensation:  Under the Company’s stock-based incentive plans, the Company compensates employees and directors with time-based restricted stock and restricted stock unit grants. Some restricted stock awards include performance-based and market-based goals that impact the number of shares that ultimately vest based on the level of goal achievement. The Company measures the cost of employee or director services received in exchange for an award of equity instruments based on the fair value of the award, which is the intrinsic value on the grant date. This cost is recognized as expense in the Consolidated Statements of Operations ratably over the vesting period of the award with forfeitures of nonvested awards recognized as they occur. Any tax benefit or deficiency is recorded as income tax benefit or expense in the period the shares vest. Excess tax benefits are classified, along with other income tax cash flows, as an operating activity. The Company issues restricted stock and restricted stock unit awards which vest over a one- or three-year period during which time, the employee or director accrues or receives dividends and may have full voting rights depending on the terms of the grant.

Earnings Per Share: Earnings per common share is computed under the two-class method. Pursuant to the two-class method, non-vested stock-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents are participating securities and are included in the computation of earnings per share. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Application of the two-class method resulted in the equivalent earnings per share to the treasury method.

Basic earnings per common share is computed by dividing net earnings allocated to common shareholders by the weighted average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Diluted earnings per common share is computed using the weighted average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock compensation, using the treasury stock method.

Comprehensive Income:  Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income.  In addition, certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, unrealized gains and losses on interest rate swaps used in cash flow hedges and changes in fair value of junior subordinated debentures related to instrument specific credit risk, are reported as a separate component of the equity section of the Consolidated Statements of Financial Condition, and such items, along with net income, are components of comprehensive income which is reported in the Consolidated Statements of Comprehensive Income.

Reclassification: Certain reclassifications have been made to the prior years’ consolidated financial statements and/or schedules to conform to the current year’s presentation. These reclassifications may have an impact on certain reported amounts and ratios for the prior periods. These reclassifications had no effect on retained earnings or net income as previously presented and the effect of these reclassifications is considered immaterial.

Accounting Changes and Error Corrections [Abstract]  
ACCOUNTING STANDARDS RECENTLY ADOPTED OR ISSUED
Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)

In November 2024, the Financial Accounting Standards Board (FASB) issued guidance within Accounting Standards Update (ASU) 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The amendments in the ASU require public companies to disclose, in the notes to financial statements, specified information about certain costs and expenses at each interim and annual reporting period. Specifically, they will be required to:
Disclose the amounts of (a) purchases of inventory; (b) employee compensation; (c) depreciation; (d) intangible asset amortization; and (e) depreciation, depletion, and amortization recognized as part of oil- and gas-producing activities (or other amounts of depletion expense) included in each relevant expense caption.
Include certain amounts that are already required to be disclosed under GAAP in the same disclosure as the other disaggregation requirements.
Disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively.
Disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses.

This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The amendments should be applied prospectively. The Company is evaluating the adoption of this ASU, but does not expect this ASU to have a material impact on the Company’s consolidated financial statements.

Compensation—Stock Compensation (Topic 718)

In March 2024, the FASB issued guidance within ASU 2024-01, Compensation—Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards. The amendments in the ASU apply to companies that provide employees and non-employees with profits interest and similar awards to align compensation with the company’s operating performance and provide those holders with the opportunity to participate in future profits and/or equity appreciation of the company. The purpose of the ASU is to clarify the application of the scope guidance in Accounting Standards Codification (ASC) paragraph 718-10-15-3 in determining if a profit interest award should be accounted for in accordance with Topic 718: Compensation—Stock Compensation. The amendment in ASC paragraph 718-10-15-3 is solely intended to improve the overall clarity and does not change the guidance.

This ASU does not have a material impact on the Company’s Consolidated Financial Statements, as the Company does not currently provide these types of awards.

Income Taxes (Topic 740)

In December 2023, the FASB issued guidance within ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in the Update are intended to provide more transparency about income tax information through improvements to income tax disclosures, primarily related to the rate reconciliation and income taxes paid information. The ASU requires disclosure in the rate reconciliation of specific categories as well as provide additional information for reconciling items that meet a quantitative threshold.

Those amendments require disclosure of the following information about income taxes paid on an annual basis:
Income taxes paid (net of refunds received), disaggregated by federal and state taxes and by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than five percent of total income taxes paid (net of refunds received).
Income tax expense (or benefit) from continuing operations disaggregated by federal and state jurisdictions.

The Company early adopted and applied this ASU prospectively and new disclosures have been added as applicable.

Segment Reporting (Topic 280)

In November 2023, the FASB issued guidance within ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU requires that a public entity that has a single reportable segment provide all the disclosures required by the amendments in this ASU and all existing disclosures in Topic 280. The Company has determined that its current business and operations consist of a single operating segment and a single reporting unit.

The amendments in this Update are intended to improve segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The key amendments included in this Update:
Require disclosure on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and are included within each reported measure of segment profit and loss.
Require disclosure on an annual and interim basis, an amount for other segment items (defined in the ASU) and a description of its composition.
Clarify that if the CODM uses more than one measure of the segment’s profit or loss in assessing performance, one or more of those additional measures may be reported.
Require disclosure of the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing performance.
The Company applied this ASU retrospectively and new disclosures have been added as applicab

At December 31, 2024, there were 201 securities—available-for-sale with unrealized losses, compared to 224 at December 31, 2023.  Management does not believe that any individual unrealized loss as of December 31, 2024 or 2023 resulted from credit loss.  The decline in fair market value of these securities was generally due to changes in interest rates and changes in market-desired spreads subsequent to their purchase.

All securities—trading were transferred to securities—available-for-sale during the fourth quarter of 2023. Net unrealized holding losses of $3.4 million were recognized in 2023.

The Company monitors the credit quality of held-to-maturity debt securities using credit ratings which are reviewed and updated quarterly. The Company’s non-rated held-to-maturity debt securities are primarily United States government sponsored enterprise debentures carrying minimal to no credit risk. The non-rated corporate bonds primarily consist of Community Reinvestment Act related bonds secured by loan instruments from low to moderate income borrowers. The remaining non-rated held-to-maturity debt securities balance is comprised of local municipal debt from within the Company’s geographic footprint and is monitored through quarterly or annual financial review. This municipal debt is predominately essential service or unlimited general obligation backed debt.

Loan amounts are net of unearned loan fees in excess of unamortized costs of $15.5 million as of December 31, 2024 and $12.1 million as of December 31, 2023. Net loans include net discounts on acquired loans of $3.5 million and $4.6 million as of December 31, 2024 and 2023, respectively. Net loans does not include accrued interest receivable. Accrued interest receivable on loans was $47.7 million as of December 31, 2024 and $47.8 million as of December 31, 2023 and was reported in accrued interest receivable on the Consolidated Statements of Financial Condition.

At December 31, 2024 and 2023, the Company had pledged $7.9 billion and $7.6 billion of loans as collateral for FHLB and other borrowings, respectively.
 
The Company’s loans to directors, executive officers and related entities are on substantially the same terms and underwriting as those prevailing at the time for comparable transactions with unrelated persons and do not involve more than normal risk of collectability.  These loans had balances of $682,600 and $708,000 at December 31, 2024 and 2023 respectively.

Purchased credit-deteriorated and purchased non-credit-deteriorated loans. Loans purchased or acquired in business combinations are recorded at their fair value at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either purchased credit-deteriorated (PCD) or purchased non-credit-deteriorated. There were no PCD loans at December 31, 2024 and 2023.
Troubled Loan Modifications. Occasionally, the Company offers modifications of loans to borrowers experiencing financial difficulty by providing principal forgiveness, interest rate reductions, other-than-insignificant payment delays, term extensions or any combination of these. When principal forgiveness is provided, the amount of the forgiveness is charged-off against the allowance for credit losses - loans. Upon the Company’s determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is charged off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses - loans is adjusted by the same amount. The allowance for credit losses on modified loans is measured using similar credit loss estimation methods used to determine the allowance for credit losses for all other loans held for investment. These methods incorporate the post-modification loan terms, as well as defaults and charge-offs associated with historical modified loans.

Credit Quality Indicators:  To appropriately and effectively manage the ongoing credit quality of the Company’s loan portfolio, Management has implemented a risk-rating or loan grading system for its loans.  The system is a tool to evaluate portfolio asset quality throughout each applicable loan’s life as an asset of the Company.  Generally, loans are risk rated on an aggregate borrower/relationship basis with individual loans sharing similar ratings.  There are some instances when specific situations relating to individual loans will provide the basis for different risk ratings within the aggregate relationship.  Loans are graded on a scale of 1 to 9.  A description of the general characteristics of these categories is shown below.

Overall Risk Rating Definitions:  Risk ratings contain both qualitative and quantitative measurements and take into account the financial strength of a borrower and the structure of the loan.  Consequently, the definitions are to be applied in the context of each lending transaction and judgment must also be used to determine the appropriate risk rating, as it is not unusual for a loan to exhibit characteristics of more than one risk-rating category.  Consideration for the final rating is centered on the borrower’s ability to repay, in a timely fashion, both principal and interest.  The Company’s risk-rating and loan grading policies are reviewed and approved annually. There were no material changes in the risk-rating or loan grading system for the periods presented.

Risk Ratings 1-5: Pass
Credits with risk ratings of 1 to 5 meet the definition of a pass risk rating. The strength of credits varies within the pass risk ratings, ranging from a risk rated 1 being an exceptional credit to a risk rated 5 being an acceptable credit that requires a more than normal level of supervision.

Risk Rating 6: Special Mention
A credit with potential weaknesses that deserves Management’s close attention is risk rated a 6.  If left uncorrected, these potential weaknesses will result in deterioration in the capacity to repay debt.  A key distinction between Special Mention and Substandard is that in a Special Mention credit, there are identified weaknesses that pose potential risk(s) to the repayment sources, versus well defined weaknesses that pose risk(s) to the repayment sources.  Assets in this category are expected to be in this category no more than 9-12 months as the potential weaknesses in the credit are resolved.

Risk Rating 7: Substandard
A credit with well-defined weaknesses that jeopardize the ability to repay in full is risk rated a 7.  These credits are inadequately protected by either the sound net worth and payment capacity of the borrower or the value of pledged collateral.  These are credits with a distinct possibility of loss.  Loans headed for foreclosure and/or legal action due to deterioration are rated 7 or worse.

Risk Rating 8: Doubtful
A credit with an extremely high probability of loss is risk rated 8.  These credits have all the same critical weaknesses that are found in a substandard loan; however, the weaknesses are elevated to the point that, based upon current information, collection or liquidation in full is improbable.  While some loss on doubtful credits is expected, pending events may make the amount and timing of any loss indeterminable.  In these situations, taking the loss is inappropriate until the outcome of the pending event is clear.

Risk Rating 9: Loss
A credit that is considered to be currently uncollectible or of such little value that it is no longer a viable bank asset is risk rated 9.  Losses should be taken in the accounting period in which the credit is determined to be uncollectible.  Taking a loss does not mean that a credit has absolutely no recovery or salvage value but, rather, it is not practical or desirable to defer writing off the credit, even though partial recovery may occur in the future.
The following tables present the Company’s portfolio of risk-rated loans by class and by grade as of December 31, 2024 and 2023 (in thousands). In addition, the tables include the gross charge-offs for the year ended December 31, 2024. Revolving loans that are converted to term loans are treated as new originations in the table below and are presented by year of origination. Term loans that are renewed or extended for periods longer than 90 days are presented as a new origination in the year of the most recent renewal or extension.

OTHER BORROWINGS
Other borrowings consist of retail and wholesale repurchase agreements, other term borrowings and Federal Reserve Bank borrowings.

Repurchase Agreements:  At December 31, 2024, retail repurchase agreements carry interest rates ranging from 0.05% to 3.94%. These repurchase agreements are secured by the pledge of certain mortgage-backed and agency securities with a carrying value of $215.6 million.  The Bank has the right to pledge or sell these securities, but it must replace them with substantially the same securities. The Bank had no borrowings under wholesale repurchase agreements at December 31, 2024 and 2023.

Federal Reserve Bank of San Francisco and fed fund lines:  The Bank periodically borrows funds on an overnight basis from the Federal Reserve Bank through the Borrower-In-Custody program.  These borrowings are secured by a pledge of eligible loans.  At December 31, 2024, based upon available unencumbered collateral, the Bank was eligible to borrow $1.52 billion from the Federal Reserve Bank. However, as of that date, as well as December 31, 2023, the Bank had no funds borrowed under this arrangement.

At December 31, 2024, the Bank had uncommitted federal funds lines of credit agreements with other financial institutions totaling $125.0 million. No balances were outstanding under these agreements as of December 31, 2024 and 2023. Availability of lines is subject to federal funds balances available for loan and continued borrower eligibility. These lines are intended to support short-term liquidity needs and the agreements may restrict consecutive day usage.

JUNIOR SUBORDINATED DEBENTURES AND MANDATORILY REDEEMABLE TRUST PREFERRED SECURITIES
At December 31, 2024, the Company had five wholly-owned subsidiary grantor trusts (the Trusts), which had issued $86.5 million of Trust Preferred Securities (TPS) to third parties, as well as $2.7 million of common capital securities, carried as other assets, which were issued to the Company.  TPS and common capital securities accrue and pay distributions periodically at specified annual rates, as provided in the indentures, based on a spread over SOFR (Secured Overnight Financing Rate).  The Trusts used the proceeds from the offerings to purchase a like amount of junior subordinated debentures (the Debentures) of the Company.  The Debentures are the sole assets of the Trusts.  The Company’s obligations under the debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the Trusts.  The TPS are mandatorily redeemable upon the maturity of the Debentures, or upon earlier redemption as provided in the indentures.  The Company has the right to redeem the Debentures in whole on or after specific dates, at a redemption price specified in the indentures plus any accrued but unpaid interest to the redemption date.  During the years ended December 31, 2024 and 2023, no debentures were redeemed. At December 31, 2024, the remaining Trusts comprised $86.5 million or 4.3% of the Company’s total risk-based capital.

(3) The interest rate spread includes a 0.26% upward adjustment for the transition from LIBOR to SOFR.

On June 30, 2020, Banner issued and sold in an underwritten offering $100.0 million aggregate principal amount of 5.00% Fixed-to-Floating Rate Subordinated Notes due 2030 (Notes) at a public offering price equal to 100% of the aggregate principal amount of the Notes, resulting in net proceeds, after underwriting discounts and estimated offering expenses, of approximately $98.1 million. The interest rate on the Notes remains fixed equal to 5.00% for the first 5 years, after 5 years the interest rate changes to a floating interest rate tied to a benchmark rate, which is expected to be Three-Month Term SOFR, plus a spread of 489 basis points. The Notes will mature on June 30, 2030. On or after June 30, 2025, the Company may redeem the Notes, in whole or in part. During 2023 and 2024, the Bank purchased a portion of these notes as an available-for-sale investment, which are eliminated upon consolidation.
The Notes are unsecured obligations and are subordinated in right of payment to all existing and future indebtedness, deposits and other liabilities of the Company’s current and future subsidiaries, including the Bank’s deposits as well as the Company’s subsidiaries’ liabilities to general creditors and liabilities arising during the ordinary course of business. The Notes are included in Tier 2 capital for the Company under current regulatory guidelines and interpretations.

At December 31, 2024, the Company had federal net operating loss carryforwards of approximately $49.9 million. The Company also has $53.0 million of state net operating loss carryforwards, against which the Company has established a $184,000 valuation reserve. The federal and state net operating losses will expire, if unused, by the end of 2034.  The Company has federal general business credit carryforwards at December 31, 2024 of $219,000, which will expire, if unused, by the end of 2031. The Company also has federal alternative minimum tax credit carryforwards of $538,000, which are available to reduce future federal regular income taxes, if any, over an indefinite period. At December 31, 2023, the Company had federal and state net operating loss carryforwards of approximately $61.7 million and $56.8 million, respectively, and federal general business credits carryforwards of $219,000 and federal alternative minimum tax credit carryforwards of approximately $538,000.

As a consequence of the Company’s 2015 acquisition of Starbuck Bancshares, Inc., the Company experienced a change in control within the meaning of Section 382 of the Code. In addition, the underlying Section 382 limitations at Starbuck Bancshares, Inc.’s level continue to apply to the Company. Section 382 limits the ability of a corporate taxpayer to use net operating loss carryforwards, general business credits, and recognized built-in-losses, on an annual basis, incurred prior to the change in control against income earned after the change in control. As a result of the Section 382 limitations, the Company is limited to utilizing $21.5 million on an annual basis (after the application of the Section 382 limitations carried over from Starbuck Bancshares, Inc.) of federal net operating loss carryforwards, general business credits, and recognized built-in losses. The applicable state Section 382 limitations range from $575,000 to $21.5 million. In 2017, the Company established a $184,000 valuation reserve against the portion of its various state net operating loss carryforwards and tax credits that it believed it is more likely than not that it would not realize the benefit because the application of the Section 382 limitations at the state level is based on future apportionment rates.

As a consequence of Banner’s capital raise in June 2010, the Company experienced a change in control within the meaning of Section 382 of the Code. As a result of the Section 382 limitations, the Company is limited to utilizing $6.9 million of net operating loss carryforwards which existed prior to the acquisition of Starbuck Bancshares, Inc., on an annual basis. Based on its analysis, the Company believes it is more likely than not that the June 2010 change in control will not impact its ability to utilize all of the related available net operating loss carryforwards, general business credits, and recognized built-in-losses. As of December 31, 2024, the Company had utilized all federal net operating losses and credits limited due to the June 2010 change in control. Certain state net operating losses subject to the change of control limitations are still outstanding.
As a consequence of the Company’s 2019 acquisition of AltaPacific and AltaPacific Bank, the Company did not experience a change in control within the meaning of Section 382 of the Code. However, the underlying Section 382 limitations at AltaPacific and AltaPacific Bank continue to apply to the Company. As a result of the Section 382 limitations, the Company is limited to utilizing $110,000 of the federal net operating loss carryovers and general business credits acquired from AltaPacific and AltaPacific Bank based on underlying limits carried over. Based on its analysis, the Company believes it is more likely than not that the Section 382 limitations will not impact its ability to utilize all of the related available net operating loss carryforwards and general business credits.

Retained earnings at December 31, 2024 and 2023 included approximately $5.4 million in tax basis bad debt reserves for which no income tax liability has been recorded.  In the future, if this tax bad debt reserve is used for purposes other than to absorb bad debts or the Company no longer qualifies as a bank or is completely liquidated, the Company will incur a federal tax liability at the then-prevailing corporate tax rate, estimated as $1.1 million at December 31, 2024.

A reconciliation of the beginning and ending amount of total unrecognized state tax benefits for the years ended December 31, 2024 and 2023, is as follows (in thousands):
 Years Ended December 31

Changes related to prior year tax positions— 149 
Changes related to current year tax positions— 251 
Balance, end of year$2,000 $2,000 

None of the unrecognized tax benefits, if recognized, would materially affect the effective tax rate. The Company does not anticipate that the amount of unrecognized tax benefits will significantly increase or decrease in the next twelve months. The Company’s policy is to recognize interest and penalties on unrecognized tax benefits in income tax expense. The amount of interest and penalties accrued for the years ended December 31, 2024, 2023 and 2022 is immaterial. The Company files consolidated income tax returns in Oregon, California, Utah, Montana and Idaho and for federal purposes. The Company is no longer subject to tax examination for tax years before 2021.

Tax credit investments: The Company invests in low income housing tax credit funds that are designed to generate a return primarily through the realization of federal tax credits. The Company accounts for these investments by amortizing the cost of tax credit investments over the life of the investment using a proportional amortization method and this tax credit investment amortization expense is a component of the provision for income taxes. The current balance of these tax credit investments is included in other assets, while the unfunded commitments are included in accrued expenses and other liabilities on the Consolidated Statements of Financial Condition.

Retirement Benefits [Abstract]  
EMPLOYEE BENEFIT PLANS
Employee Retirement Plans: Substantially all Company and Bank employees are eligible to participate in its 401(k)/Profit Sharing Plan, a defined contribution and profit sharing plan sponsored by the Company. Employees may elect to have a portion of their salary contributed to the plan in conformity with Section 401(k) of the Internal Revenue Code. At the discretion of the Company’s Board of Directors, the Company may elect to make matching and/or profit-sharing contributions for the employees’ benefit. For the years ended December 31, 2024, 2023 and 2022, $7.1 million, $6.7 million and $6.9 million, respectively, was expensed for the Company’s 401(k) contributions. During 2024, the Board of Directors elected to make a matching contribution of 4% of eligible compensation.
Supplemental Retirement and Salary Continuation Plans:  Through the Bank, the Company is obligated under various non-qualified deferred compensation plans to help supplement the retirement income of certain executives, including certain retired executives, selected by resolution of the Bank’s Boards of Directors or in certain cases by the former directors of acquired banks.  These plans are unfunded, include both defined benefit and defined contribution plans, and provide for payments after the executive’s retirement.  In the event of a participant employee’s death prior to or during retirement, the Company is obligated to pay to the designated beneficiary the benefits set forth under the plan.  For the years ended December 31, 2024, 2023 and 2022, expense recorded for supplemental retirement and salary continuation plan benefits totaled $2.2 million, $2.5 million, and $2.0 million, respectively.  At December 31, 2024 and 2023, liabilities recorded for the various supplemental retirement and salary continuation plan benefits totaled $34.8 million and $36.1 million, respectively, and are recorded in a deferred compensation liability account.

Deferred Compensation Plans and Rabbi Trusts:  The Company and the Bank also offer non-qualified deferred compensation plans to members of their Boards of Directors and certain employees.  The plans permit each participant to defer a portion of director fees, non-qualified retirement contributions, salary or bonuses for future receipt.  Compensation is charged to expense in the period earned.  In connection with its acquisitions, the Company also assumed liability for certain deferred compensation plans for key employees, retired employees and directors.

In order to fund the plans’ future obligations, the Company has purchased life insurance policies or other investments, including Banner common stock, which in certain instances are held in irrevocable trusts commonly referred to as “Rabbi Trusts.”  As the Company is the owner of the investments and the beneficiary of the insurance policies, and in order to reflect the Company’s policy to pay benefits equal to the accumulations, the assets and liabilities are reflected in the Consolidated Statements of Financial Condition.  Banner common stock held for such plans is reported as a contra-equity account and was recorded at an original cost of $6.2 million at December 31, 2024 and $6.6 million at December 31, 2023.  At December 31, 2024 and 2023, liabilities recorded in connection with deferred compensation plan benefits totaled $18.8 million ($6.2 million in contra-equity) and $15.8 million ($6.6 million in contra-equity), respectively, and are recorded in deferred compensation or equity as appropriate.

The Bank has purchased, or acquired through mergers, life insurance policies in connection with the implementation of certain executive supplemental retirement, salary continuation and deferred compensation retirement plans, as well as additional policies not related to any specific plan. These policies provide protection against the adverse financial effects that could result from the death of a key employee and provide tax-exempt income to offset expenses associated with the plans.  It is the Bank’s intent to hold these policies as a long-term investment.  However, there will be an income tax impact if the Bank chooses to surrender certain policies.  Although the lives of individual current or former management-level employees are insured, the Bank is the owner and sole or partial beneficiary.  At December 31, 2024 and 2023, the cash surrender value of these policies was $312.5 million and $304.4 million, respectively.  The Bank is exposed to credit risk to the extent an insurance company is unable to fulfill its financial obligations under a policy.  In order to mitigate this risk, the Bank uses a variety of insurance companies and regularly monitors their financial condition.

At December 31, 2024, Banner and the Bank each exceeded the requirements to be “well capitalized” and the fully phased-in capital conservation buffer requirement. There have been no conditions or events since December 31, 2024 that have materially adversely changed the Tier 1 or Tier 2 capital of the Company or the Bank. However, events beyond the control of the Bank, such as weak or depressed economic conditions in areas where the Bank has most of its loans, could adversely affect future earnings and, consequently, the ability of the Bank to meet its respective capital requirements. The Company may not declare or pay cash dividends on, or repurchase, any of its shares of common stock if the effect thereof would cause equity to be reduced below applicable regulatory capital maintenance requirements or if such declaration and payment would otherwise violate regulatory requirements.

Other Intangible Assets and Mortgage Servicing Rights [Abstract]  
OTHER INTANGIBLE ASSETS AND MORTGAGE SERVICING RIGHTS
Goodwill and Other Intangible Assets: At December 31, 2024, intangible assets are comprised of goodwill and CDI acquired in business combinations. Goodwill is not amortized but is reviewed at least annually for impairment. Banner has identified one reporting unit for purposes of evaluating goodwill for impairment. At December 31, 2024, the Company completed an assessment of qualitative factors and concluded that no further analysis was required as it is more likely than not that the fair value of the Bank, the reporting unit, exceeds the carrying value.

CDI represents the value of transaction-related deposits and the value of the client relationships associated with the deposits. The Company amortizes CDI assets over their estimated useful lives and reviews them at least annually for events or circumstances that could impair their value.  The CDI assets shown in the table below represent the value ascribed to the long-term deposit relationships acquired in various bank acquisitions.
The following table summarizes the changes in the Company’s goodwill and other intangibles for the years ended December 31, 2024, 2023 and 2022 (in thousands):

Mortgage Servicing Rights: Mortgage and SBA servicing rights are reported in other assets.  SBA servicing rights are initially recorded and carried at fair value. Mortgage servicing rights are initially recognized at fair value and are amortized in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets.  Mortgage servicing rights are subsequently evaluated for impairment based upon the fair value of the rights compared to the amortized cost (remaining unamortized initial fair value).  If the fair value is less than the amortized cost, a valuation allowance is created through an impairment charge to servicing fee income.  However, if the fair value is greater than the amortized cost, the amount above the amortized cost is not recognized in the carrying value.  In 2024, 2023 and 2022, the Company did not record any impairment charges or recoveries against mortgage servicing rights. Unpaid principal balance of loans for which mortgage and SBA servicing rights have been recognized totaled $2.84 billion and $2.78 billion at December 31, 2024 and 2023, respectively.  Custodial accounts maintained in connection with this servicing totaled $12.2 million and $11.6 million at December 31, 2024 and 2023, respectively.

(1)    Amortization of mortgage servicing rights is recorded as a reduction of loan servicing income within mortgage banking operations and any unamortized balance is fully amortized if the loan repays in full.
(2)    Fair value adjustments relate to SBA servicing rights. These adjustments are estimated based on an independent dealer analysis by discounting estimated net future cash flows from servicing SBA loans.

The Company measures and discloses certain assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (that is, not a forced liquidation or distressed sale). When measuring fair value, Management will maximize the use of observable inputs and minimize the use of unobservable inputs whenever possible. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s estimates for market assumptions.

The estimated fair value amounts of financial instruments have been determined by the Company using available market information and appropriate valuation methodologies.  However, considerable judgment is required to interpret data to develop the estimates of fair value.  Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize at a future date.  The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.  In addition, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates that must be made given the absence of active secondary markets for many of the financial instruments.  This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values.

(1)    The unpaid principal balance of one- to four family residential loans held for sale carried at fair value on a recurring basis was $25.7 million and $8.8 million at December 31, 2024 and 2023, respectively.

The following methods were used to estimate the fair value of each class of financial instruments above:

Securities:  The estimated fair values of investment securities and mortgage-backed securities are priced using current active market quotes, if available, which are considered Level 1 measurements.  For most of the portfolio, matrix pricing based on the securities’ relationship to other benchmark quoted prices is used to establish the fair value.  These measurements are considered Level 2.  Due to the continued limited activity in the trust preferred markets that have limited the observability of market spreads for some of the Company’s TPS securities, Management has classified these securities, included in Corporate Bonds, as a Level 3 fair value measure. Management periodically reviews the pricing information received from third-party pricing services and tests those prices against other sources to validate the reported fair values.

Loans Held for Sale: Fair values for residential mortgage loans held for sale are determined by comparing actual loan rates to current secondary market prices for similar loans.

Equity Securities: Equity securities are invested in a publicly traded stock. The fair value of these securities is based on daily quoted market prices.

SBA Servicing Rights: Fair values are estimated based on an independent dealer analysis by discounting estimated net future cash flows from servicing. The evaluation utilizes assumptions market participants would use in determining fair value including prepayment speeds, delinquency and foreclosure rates, the discount rate, servicing costs, and the timing of cash flows.  The SBA servicing portfolio is stratified by loan type and fair value estimates are adjusted up or down based on the serviced loan interest rates versus current rates on new loan originations since the most recent independent analysis.
Junior Subordinated Debentures:  The fair value of junior subordinated debentures is estimated using an income approach technique. The significant inputs included in the estimation of fair value are the credit risk adjusted spread and three month SOFR. The credit risk adjusted spread represents the nonperformance risk of the liability. The Company utilizes an external valuation firm to validate the reasonableness of the credit risk adjusted spread used to determine the fair value. The junior subordinated debentures are carried at fair value which represents the estimated amount that would be paid to transfer these liabilities in an orderly transaction amongst market participants. Due to inactivity in the trust preferred markets that have limited the observability of market spreads, Management has classified this as a Level 3 fair value measurement.

Derivatives: Derivatives include interest rate swap agreements, interest rate lock commitments to originate loans held for sale, forward sales contracts to sell loans and securities related to mortgage banking activities and risk participation agreements. Fair values for these instruments, which generally change as a result of changes in the level of market interest rates, are estimated based on dealer quotes and secondary market sources. As the interest rate lock commitments use a pull-through rate that is considered an unobservable input, these derivatives are classified as a level 3 fair value measurement.

Off-Balance Sheet Items: Off-balance sheet financial instruments include unfunded commitments to extend credit, including standby letters of credit, and commitments to purchase investment securities. The fair value of these instruments is not considered to be material.

Limitations: The fair value estimates presented herein are based on pertinent information available to Management as of December 31, 2024 and 2023.  The factors used in the fair value estimates are subject to change subsequent to the dates the fair value estimates are completed; therefore, current estimates of fair value may differ significantly from the amounts presented herein.

Assets and Liabilities Measured at Fair Value Using Significant Unobservable Inputs (Level 3):

The following table provides a description of the valuation technique, unobservable inputs and quantitative and qualitative information about the unobservable inputs for the Company’s assets and liabilities classified as Level 3 and measured at fair value on a recurring and non-recurring basis at December 31, 2024 and 2023:

Interest rate lock commitmentsPricing modelPull-through rate92.34 %88.24 %
SBA servicing rightsDiscounted cash flowsConstant prepayment rate18.85 %16.92 %

TPS: Management believes that the credit risk-adjusted spread used to develop the discount rate utilized in the fair value measurement of TPS is indicative of the risk premium a willing market participant would require under current market conditions for instruments with similar contractual rates and terms and conditions and issuers with similar credit risk profiles and with similar expected probability of default. Management attributes the change in fair value of these instruments, compared to their par value, primarily to perceived general market adjustments to the risk premiums for these types of assets subsequent to their issuance.

Junior subordinated debentures: Similar to the TPS discussed above, Management believes the credit risk-adjusted spread utilized in the fair value measurement of the junior subordinated debentures is indicative of the risk premium a willing market participant would require under current market conditions for an issuer with Banner’s credit risk profile. Management attributes the change in fair value of the junior subordinated debentures, compared to their par value, primarily to perceived general market adjustments to the risk premiums for these types of liabilities subsequent to their issuance. Future contractions in the risk-adjusted spread relative to the spread currently utilized to measure the Company’s junior subordinated debentures at fair value as of December 31, 2024, or the passage of time, will result in negative fair value adjustments. At December 31, 2024, the discount rate utilized was based on a credit spread of 526 basis points and three month SOFR of 431 basis points.

Interest rate lock commitments: The fair value of the interest rate lock commitments is based on secondary market sources adjusted for an estimated pull-through rate. The pull-through rate is based on historical loan closing rates for similar interest rate lock commitments. An increase or decrease in the pull-through rate would have a corresponding, positive or negative fair value adjustment.

SBA servicing asset: The constant prepayment rate (CPR) is set based on industry data. An increase in the CPR would result in a negative fair value adjustment, where a decrease in CPR would result in a positive fair value adjustment.
The following table provides a reconciliation of the assets and liabilities measured at fair value using significant unobservable inputs (Level 3) on a recurring basis during the years ended December 31, 2024 and 2023 (in thousands):

Interest income, dividends and amortization related to TPS are recorded as a component of interest income. Interest expense related to the junior subordinated debentures is measured based on contractual interest rates and reported in interest expense. The change in fair value of the junior subordinated debentures, which represents changes in instrument specific credit risk. The change in fair value of the TPS was recorded as a component of non-interest income when it was held for trading. After the transfer of the TPS to available-for-sale in late 2023, the change in fair value is recorded in other comprehensive income. The change in fair value of the investment in limited partnerships and the SBA servicing asset are recorded as a component of non-interest income. The change in fair value of the interest rate lock and forward sales commitments are included in mortgage banking operations in non-interest income.

(1) Gains and losses related to loans held for sale were due to the multifamily real estate loans held for sale until the loans were transferred to loans held in portfolio in the fourth quarter of 2023.
Loans individually evaluated: Expected credit losses for loans evaluated individually are measured based on the present value of expected future cash flows discounted at the loan’s original effective interest rate or when the Bank determines that foreclosure is probable, the expected credit loss is measured based on the fair value of the collateral as of the reporting date, less estimated selling costs, as applicable. As a practical expedient, the Bank measures the expected credit loss for a loan using the fair value of the collateral, if repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the Bank’s assessment as of the reporting date. In both cases, if the fair value of the collateral is less than the amortized cost basis of the loan, the Bank will recognize an allowance as the difference between the fair value of the collateral, less costs to sell (if applicable) and the amortized cost basis of the loan. If the fair value of the collateral exceeds the amortized cost basis of the loan, any expected recovery added to the amortized cost basis will be limited to the amount previously charged-off. Subsequent changes in the expected credit losses for loans evaluated individually are included within the provision for credit losses in the same manner in which the expected credit loss initially was recognized or as a reduction in the provision that would otherwise be reported.

REO: The Company records REO (acquired through a lending relationship) at fair value on a non-recurring basis. Fair value adjustments on REO are based on updated real estate appraisals which are based on current market conditions. All REO properties are recorded at the lower of the estimated fair value of the real estate, less expected selling costs, or the carrying amount of the defaulted loans. From time to time, non-recurring fair value adjustments to REO are recorded to reflect partial write-downs based on an observable market price or current appraised value of property. Banner considers any valuation inputs related to REO to be Level 3 inputs. The individual carrying values of these assets are reviewed for impairment at least annually and any additional impairment charges are expensed.

Commitments and Contingencies Disclosure [Abstract]  
COMMITMENTS AND CONTINGENCIES
Financial Instruments with Off-Balance Sheet Risk - The Company has financial instruments with off-balance-sheet risk generated in the normal course of business to meet the financing needs of its clients.  These financial instruments include commitments to extend credit, commitments related to standby letters of credit, commitments to originate loans, commitments to sell loans, and commitments to buy or sell securities. These instruments involve, to varying degrees, elements of credit and interest rate risk similar to the risk involved in on-balance sheet items.

Our exposure to credit loss in the event of nonperformance by the other party to the financial instrument from commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments.  We use the same credit policies in making commitments and conditional obligations as on-balance sheet instruments.

Outstanding commitments consisted of the following at the dates indicated (in thousands):

Commitments to sell securities related to mortgage banking activities37,500 17,000 

In addition to the commitments disclosed in the table above, the Company is also committed to funding the unfunded portion of its tax credit investments, as discussed previously in Note 10, Income Taxes, as well as the remaining unfunded portion of its investments in limited partnerships. As of December 31, 2024 and 2023, the remaining outstanding commitments related to the unfunded tax credit investments and limited partnership investments were as follows (in thousands):
Unfunded commitment balance for:December 31, 2024December 31, 2023
Tax credit investments$94,416 $62,594 
Limited partnerships investments$14,706 $10,462 

Commitments to extend credit are agreements to lend to a client, as long as there is no violation of any condition established in the contract.  Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee.  Many of the commitments may expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements.  Each client’s creditworthiness is evaluated on a case-by-case basis.  The amount of collateral obtained, if deemed necessary upon extension of credit, is based on Management’s credit evaluation of the client.  Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, and income producing commercial properties. The Company’s allowance for credit losses - unfunded loan commitments was $13.6 million and $14.5 million at December 31, 2024 and 2023, respectively.

Standby letters of credit are conditional commitments issued to guarantee a client’s performance or payment to a third party.  The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to clients. Under a risk participation agreement, the Bank guarantees the financial performance of a borrower on the participated portion of an interest rate swap on a loan.

Interest rates on one- to four-family residential loan applications are typically rate locked (committed) to clients during the application stage for periods ranging from 30 to 60 days, the most typical period being 45 days. Traditionally, these loan applications with rate lock commitments have the pricing for the sale of these loans locked with various qualified investors under a best-efforts delivery program at or near the time the interest rate is locked with the client. The Bank then attempts to deliver these loans before their rate locks expire. This arrangement generally requires delivery of the loans prior to the expiration of the rate lock. Delays in funding the loans may require a lock extension. The cost of a lock extension is sometimes covered by the client and other times by the Bank. These lock extension costs have not had a material impact to the Company’s operations. For mandatory delivery commitments the Company enters into forward commitments at specific prices and settlement dates to deliver either: (1) residential mortgage loans for purchase by secondary market investors (i.e., Freddie Mac or Fannie Mae), or (2) mortgage-backed securities to broker/dealers. The purpose of these forward commitments is to offset the movement in interest rates between the execution of its residential mortgage rate lock commitments with borrowers and the sale of those loans to the secondary market investor. There were no counterparty default losses on forward contracts during 2024 and 2023. Market risk with respect to forward contracts arises principally from changes in the value of contractual positions due to changes in interest rates. The Company limits its exposure to market risk by monitoring differences between commitments to clients and forward contracts with market investors and securities broker/dealers. In the event the Company has forward delivery contract commitments in excess of available mortgage loans, the transaction is completed by either paying or receiving a fee to or from the investor or broker/dealer equal to the increase or decrease in the market value of the forward contract. Changes in the value of rate lock commitments are recorded as assets and liabilities.
In the normal course of business, the Company and/or its subsidiaries have various legal proceedings and other contingent matters outstanding.  These proceedings and the associated legal claims are often contested and the outcome of individual matters is not always predictable.  These claims and counterclaims typically arise during the course of collection efforts on problem loans or with respect to action to enforce liens on properties in which the Bank holds a security interest.  Based upon the information known to Management, there were no legal proceedings, pending or threatened, that Management believes would have a material adverse effect on the results of operations or consolidated financial position at December 31, 2024.

In connection with certain asset sales, the Bank typically makes representations and warranties about the underlying assets conforming to specified guidelines.  If the underlying assets do not conform to the specifications, the Bank may have an obligation to repurchase the assets or indemnify the purchaser against any loss.  The Bank believes that the potential for material loss under these arrangements is remote.  Accordingly, the fair value of such obligations is not material.

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
DERIVATIVES AND HEDGING
The Company is party to various derivative instruments that are used for asset and liability management and client financing needs. Derivative instruments are contracts between two or more parties that have a notional amount and an underlying variable, require no net investment and allow for the net settlement of positions. The notional amount serves as the basis for the payment provision of the contract and takes the form of units, such as shares or dollars. The underlying variable represents a specified interest rate, index, or other component. The interaction between the notional amount and the underlying variable determines the number of units to be exchanged between the parties and influences the market value of the derivative contract.

The Company’s predominant derivative and hedging activities involve interest rate swaps related to certain term loans and forward sales contracts associated with mortgage banking activities. Generally, these instruments help the Company manage exposure to market risk and meet client financing needs. Market risk represents the possibility that economic value or net interest income will be adversely affected by fluctuations in external factors such as market-driven interest rates and prices or other economic factors.

The Company’s asset derivatives are included in other assets, while the liability derivatives are included in accrued expenses and other liabilities on the Consolidated Statements of Financial Condition.

Interest Rate Swaps used in Cash Flow Hedges: During the fourth quarter of 2021, the Company entered into interest rate swaps designated as cash flow hedges to hedge the variable cash flows associated with existing floating rate loans. These hedge contracts involved the receipt of fixed-rate payments from a counterparty in exchange for the Company making floating-rate payments over the life of the agreements without the exchange of the underlying notional amount. In late 2024, these interest rate swap derivatives matured.

Since the derivatives were designated and qualified as cash flow hedges, the unrealized gains and losses on these derivatives were recorded in AOCI and subsequently reclassified into interest income in the same period that the hedged transaction affected earnings. Amounts reported in AOCI related to the derivatives were reclassified to interest income as interest payments were made on the Company’s variable-rate assets. As these derivatives have matured, no additional amounts will be reclassified as a decrease to interest income.
The following table presents the effect of cash flow hedge accounting on AOCI for the years ended December 31, 2024 and 2023 (in thousands):

At December 31, 2024, no net unrealized gains or losses on cash flow hedges remain in AOCI, compared to a loss of $10.6 million at December 31, 2023.

Interest Rate Swaps: The Bank offers an interest rate swap program for commercial loan clients that provides the client with a variable-rate loan and enters into an interest rate swap in which the client receives a variable-rate payment in exchange for a fixed-rate payment. The Bank offsets its risk exposure by entering into an offsetting interest rate swap with a dealer counterparty for the same notional amount and length of term as the client interest rate swap providing the dealer counterparty with a fixed-rate payment in exchange for a variable-rate payment. These swaps do not qualify as designated hedges; therefore, each swap is accounted for as a freestanding derivative.

Risk Participation Agreements: In conjunction with the purchase or sale of participating interests in loans, the Company also participates in related swaps through risk participation agreements. The existing credit derivatives resulting from these participations are not designated as hedges as they are not used to manage interest rate risk in the Company’s assets or liabilities and are not speculative.

Mortgage Loan Commitments: The Company sells originated one- to four-family residential loans into the secondary mortgage loan markets. During the period of loan origination and prior to the sale of the loans in the secondary market, the Company has exposure to movements in interest rates associated with written interest rate lock commitments with potential borrowers to originate one- to four-family residential loans that are intended to be sold and for closed one- to four-family residential loans held for sale for which fair value accounting has been elected, that are awaiting sale and delivery into the secondary market. The Company economically hedges the risk of changing interest rates associated with these one- to four-family residential loan commitments by entering into forward sales contracts to sell these loans or mortgage-backed securities to broker/dealers at specific prices and dates.

The Company is exposed to credit-related losses in the event of nonperformance by the counterparty to these agreements. Credit risk of the financial contract is controlled through the credit approval, limits, and monitoring procedures and Management does not expect the counterparties to fail their obligations.
In connection with the interest rate swaps between the Bank and the dealer counterparties, the agreements contain a provision where if the Bank fails to maintain its status as a well or adequately capitalized institution, then the counterparty could terminate the derivative positions and the Bank would be required to settle its obligations. Similarly, the Bank could be required to settle its obligations under certain of its agreements if specific regulatory events occur, such as a publicly issued prompt corrective action directive, cease and desist order, or a capital maintenance agreement that required the Bank to maintain a specific capital level. If the Bank had breached any of these provisions, it could have been required to settle its obligations under the agreements at the termination value. As of December 31, 2024 and 2023, the Company had no obligations to dealer counterparties related to these agreements. The Company generally posts collateral against derivative liabilities in the form of cash, government agency-issued bonds, mortgage-backed securities, or commercial mortgage-backed securities. Collateral posted against derivative liabilities was $19.9 million and $15.0 million as of December 31, 2024 and 2023, respectively. The collateral posted included restricted cash of $18.9 million and $14.0 million as of December 31, 2024 and 2023, respectively.

Derivative assets and liabilities are recorded at fair value on the balance sheet. Master netting agreements allow the Company to settle all derivative contracts held with a single counterparty on a net basis and to offset net derivative positions with related collateral where applicable. In addition, some interest rate swap derivatives between the Company and the dealer counterparties are cleared through central clearing houses. These clearing houses characterize the variation margin payments as settlements of the derivative’s market exposure and not as collateral. The variation margin is treated as an adjustment to our cash collateral, as well as a corresponding adjustment to our derivative asset or liability. As of December 31, 2024 and 2023, the variation margin adjustment was a positive adjustment of $15.6 million and negative adjustment of $529,000, respectively.

Total deposit fees and other service charges$43,371 $41,638 $44,459 

Deposit fees and other service charges

Deposit fees and other service charges include transaction and non-transaction based deposit fees. Transaction based fees on deposit accounts are charged to deposit clients for specific services provided to them. These fees include such items as wire fees, official check fees, and overdraft fees. These are contract specific to each individual transaction and do not extend beyond the individual transaction. The performance obligation is completed, and the fees are recognized, at the time the specific transactional service is provided to the client. Non-transactional deposit fees are typically monthly account maintenance fees charged on deposit accounts. These are day-to-day contracts that can be canceled by either party without notice. The performance obligation is satisfied, and the fees are recognized, on a monthly basis after the service period is completed.

Debit and credit card interchange income and expenses

Debit and credit card interchange income represent fees earned when a credit or debit card issued by the Bank is used to purchase goods or services at a merchant. The merchant’s bank pays the Bank a default interchange rate set by Mastercard on a transaction-by-transaction basis. The merchant acquiring bank can stop accepting the Bank’s cards at any time and the Bank can stop further use of cards issued by them at any time. The performance obligation is satisfied, and the fees are earned, when the cost of the transaction is charged to the Bank’s cardholders’ card. Direct expenses associated with the credit and debit card are recorded as a net reduction against the interchange income.

Merchant services income

Merchant services income represents fees earned by the Bank for card payment services provided to its merchant clients. The Bank has a contract with a third party to provide card payment services to the Bank’s merchants that contract for those services. The third party provider has contracts with the Bank’s merchants to provide the card payment services. The Bank does not have a direct contractual relationship with its merchants for these services. The Bank sets the rates for the services provided by the third party. The third party provider passes the payments made by the Bank’s merchants through to the Bank. The Bank, in turn, pays the third party provider for the services it provides to the Bank’s merchants. These payments to the third party provider are recorded as expenses as a net reduction against fee income. In addition, a portion of the payment received by the Bank represents interchange fees passed through to the card issuing bank. Income is primarily earned based on the dollar volume and number of transactions processed. The performance obligation is satisfied and the related fee is earned when each payment is accepted by the processing network.

Segment Reporting [Abstract]  
Segment Reporting Disclosure
The Company is managed by legal entity, rather than by lines of business, and its activities are considered a single operating segment for financial reporting purposes. The Bank is engaged in the single line of business of community banking, which involves gathering deposits and originating loans in its primary market areas. The Bank manages its operations, allocates resources, and monitors and reports its financials as a single operating segment.

Banner’s Chief Executive Officer is considered the Chief Operating Decision Maker (CODM). The CODM assesses performance based on net income that is reported on our Consolidated Statements of Operations. The CODM uses consolidated net income as the primary measure to evaluate resource allocations. In addition to our consolidated financial statements, specifically the statement of operations and the statement of cash flows, the operating and financial condition data below is used to monitor budget versus actual results and assess performance:

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
Our cybersecurity risk management and strategy are integrated into our enterprise-wide risk management program, leveraging a “three lines of defense” model to manage risk within the organization. Technology risk (including cybersecurity risk) is considered to be a key risk area for the Company, with Management measuring inherent risk, mitigating controls, and residual risk on a quarterly basis.

The ability to mitigate cybersecurity risks depends on an effective risk assessment process that identifies, measures, controls, and monitors material risks from cybersecurity threats. These threats include any potential unauthorized activities that could compromise the confidentiality, integrity, or availability of the Company’s information systems and data. Our Information Security Program includes a comprehensive information security risk assessment process that incorporates the following elements:

Identifying threats, measuring risk, defining information security requirements, and implementing controls to reduce risk.
Identifying reasonably foreseeable internal and external threats that may lead to unauthorized disclosure, misuse, alteration, or destruction of sensitive information or information systems.
Assessing the likelihood and potential damage posed by these threats, considering the degree of information sensitivity and the Company’s operations, inclusive of substantive changes to people, processes and technology.
Aligning the Information Security Program with the Company’s enterprise-wide risk management program, which identifies, measures, mitigates, and monitors risk.
Evaluating the adequacy of policies, procedures, information systems, and other arrangements designed to control identified risks, considering the Company’s operations, inclusive of substantive changes to people, processes and technology.
Conducting internal and third-party security assessments, including penetration testing.
Overseeing third-party vendor risk through due diligence and monitoring.

The risk assessment process is designed to identify assets requiring risk reduction strategies and includes an evaluation of the key factors applicable to the operation. The Company conducts a variety of information security assessments throughout the year, both internally and through third-party specialists.

In designing our Information Security Program, we refer to established industry frameworks – in particular, the Federal Financial Institutions Examination Council (FFIEC) and guidance from the International Organization for Standardization (ISO). The FFIEC framework offers a set of guidelines to help financial institutions effectively manage and mitigate cybersecurity risks. ISO/IEC 27001 is an international standard developed by the ISO specifically for Information Security, Cybersecurity and Privacy Protection (ISCPP). These frameworks provide best practices for managing cybersecurity risks and ensuring information security, and we consider them to be aspirational benchmarks to help inform the design of our Information Security Program. While our program is designed to be robust, the sophistication and evolving nature of cyber threats mean no system can fully eliminate risk. For more information on how cybersecurity risk may affect the Company’s business strategy, results of operations or financial condition, please refer to Item 1A, Risk Factors — Risks Related to Cybersecurity, Data and Fraud.

The Company uses a cross-functional approach to identify, prevent, and mitigate cybersecurity threats and incidents. We have established procedures for the timely escalation and, when required, disclosure of cybersecurity incidents, supported by a formal incident response plan that outlines the steps the Company will take to respond to a cybersecurity incident. While cybersecurity risks could materially affect the Company, past incidents have not materially affected our business strategy, results of operations or financial condition. For further details on potential cybersecurity risks, see Item 1A, Risk Factors — Risks Related to Cybersecurity, Data and Fraud.

Governance

Our Board of Directors annually reviews and approves the Company’s Risk Appetite Statement, which defines key risk categories and associated metrics that are monitored quarterly by Management and reported to the Risk Committee. Management measures and reports inherent risk, mitigating controls, and residual risk for each key risk category and identifies and regularly discusses emerging risks with the Risk Committee.

The Company’s governance and oversight of cybersecurity risks are facilitated through our Information Security Program, which establishes administrative, technical, and physical safeguards designed to protect sensitive information in accordance with FDIC and FFIEC regulations. The program is tailored to align with the Company’s size, complexity and operational scope.

Cybersecurity risk management is led by our Chief Information Officer (CIO) and Chief Information Security Officer (CISO), supported by our information technology and information security teams. The Bank’s Chief Information Officer (CIO) provides direction and oversight for information technology and security across the Company, including existing and emerging initiatives. In this role, she leverages more than 26 years of information technology experience. The Bank’s Chief Information Security Officer (CISO) has been with the Company for more than 13 years and has maintained various applicable cybersecurity and IT audit certifications. Prior to joining the Bank, he worked for a Fortune 500 company and had 15 years of information technology experience working in networking, information security and information technology auditing.
Our Information Technology (IT) Management team is responsible for conducting risk assessments, designing the Information Security Program, overseeing service provider arrangements, establishing risk-based response programs for incidents involving unauthorized data access, providing staff training, conducting testing of key controls, systems, and procedures, and adjusting the program to reflect changes in people, processes, technology, sensitive information, threats, and the business environment (e.g., mergers, acquisitions, alliances, joint ventures, or outsourcing arrangements).

Our IT Management team reports annually to the Risk Committee on the status of the Information Security Program, including risk assessment, risk management and control decisions, service provider arrangements, results of independent testing, cybersecurity incidents and recommendations for improvements. Quarterly status updates are also provided to the Risk Committee.

The Board of Directors plays a crucial role, annually reviewing and approving our Information Security Program. The Board oversees efforts to develop, implement, and maintain an effective Information Security Program, including reviewing Management’s reporting on program effectiveness. The Board of Directors’ Corporate Governance/Nominating Committee considers IT and cybersecurity expertise when assessing potential director candidates to help ensure effective oversight by the Board of Directors.

We maintain a Cybersecurity Incident Response Team (CIRT) to handle technical aspects of the Company’s response to cybersecurity events and an Executive Cybersecurity Event Evaluation Team (ECEET) to assess potential business impacts and disclosure requirements related to cybersecurity events. Both teams may engage cybersecurity legal counsel and other external experts in connection with their respective activities. An escalation process facilitates updates to internal governance groups, including the Company’s Disclosure Committee and/or the Board of Directors’ Audit Committee, each of which also receives a quarterly report from the ECEET chair.

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)
12 Months Ended

subsidiary
Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Principles of Consolidation Principles of Consolidation:  The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary.  All material intercompany transactions, profits and balances have been eliminated. The consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) and under the rules and regulations of the U.S. Securities and Exchange Commission (the SEC). At December 31, 2024, the Company had five wholly-owned subsidiary grantor trusts (the Trusts), each of which issued trust preferred securities (TPS) and common securities. The Trusts are not consolidated in the Company’s consolidated financial statements.
Number of Wholly-owned Grantor Trusts 5
Business Segments
Operating Segments:  The Company’s operations are managed, and financial performance is evaluated, by our chief operating decision maker on a Company-wide basis.  The Bank’s primary business is that of a traditional banking institution, gathering deposits and originating loans for portfolio in its primary market areas.  The Bank offers a wide variety of deposit products to its consumer and commercial clients.  Lending activities include the origination of real estate, commercial/agriculture business and consumer loans.  The performance of the Company is reviewed monthly by the Company’s executive management and Board of Directors.  As resource allocation and performance decisions are not made based on discrete financial information of individual lines of business, the Company considers its current business and operations as a single reportable operating segment.
Subsequent Events
Subsequent Events: The Company has evaluated events and transactions subsequent to December 31, 2024 through the date that the consolidated financial statements were issued for potential recognition or disclosure.
Cash and Cash Equivalents, Policy
Cash and Cash Equivalents: Cash and cash equivalents include cash and due from banks and temporary investments which are federal funds sold and interest bearing balances due from other banks. Cash and cash equivalents generally have maturities of three months or less at the date of purchase.
Business Combinations
Business Combinations: Business combinations are accounted for using the acquisition method of accounting and, accordingly, assets acquired and liabilities assumed, both tangible and intangible, and consideration exchanged are recorded at acquisition date fair values. The excess purchase consideration over fair value of net assets acquired is recorded as goodwill. In the event that the fair value of net assets acquired exceeds the purchase price, including fair value of liabilities assumed, a bargain purchase gain is recorded on that acquisition. Expenses incurred in connection with a business combination are expensed as incurred, except for those items permitted to be capitalized. Changes in deferred tax asset valuation allowances related to acquired tax uncertainties are recognized in net income after the measurement period.
Use of Estimates
Use of Estimates:  In the opinion of Management, the accompanying Consolidated Statements of Financial Condition and related Consolidated Statements of Operations, Comprehensive Income (Loss), Changes in Shareholders’ Equity and Cash Flows reflect all adjustments (which include reclassification and normal recurring adjustments) that are necessary for a fair presentation in conformity with GAAP.  The preparation of financial statements in conformity with GAAP requires Management to make estimates and assumptions that affect amounts reported in the financial statements.

Various elements of the Company’s accounting policies, by their nature, are inherently subject to estimation techniques, valuation assumptions and other subjective assessments.  Management has identified several accounting policies that, due to the judgments, estimates and assumptions inherent in those policies, are critical to an understanding of Banner’s Consolidated Financial Statements.  These policies relate to (i) determination of the provision and allowance for credit losses, (ii) the valuation of financial assets and liabilities recorded at fair value, and (iii) the valuation or recognition of deferred tax assets and liabilities. Management believes that the judgments, estimates and assumptions used in the preparation of the consolidated financial statements are appropriate based on the factual circumstances at the time.  However, given the sensitivity of the Consolidated Financial Statements to these critical accounting estimates, the use of judgments, estimates and assumptions could result in material differences in the Company’s results of operations or financial condition.  Further, subsequent changes in economic or market conditions could have a material impact on these estimates and the Company’s financial condition and operating results in future periods.
Securities
Securities: Debt securities are classified as held-to-maturity when the Company has the ability and positive intent to hold them to maturity.  Debt securities classified as available-for-sale are available for future liquidity requirements and may be sold prior to maturity.  Debt securities classified as trading are also available for future liquidity requirements and may be sold prior to maturity.  Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities.  Debt securities classified as held-to-maturity are carried at cost, net of the allowance for credit losses - securities, adjusted for amortization of premiums to the earliest callable date and accretion of discounts to maturity.  Debt securities classified as available-for-sale are measured at fair value.  Unrealized holding gains and losses on debt securities classified as available-for-sale are excluded from earnings and are reported net of tax as accumulated other comprehensive income (AOCI), a component of shareholders’ equity, until realized.  Debt securities classified as trading are also measured at fair value.  Unrealized holding gains and losses on securities classified as trading are included in earnings.  Realized gains and losses on sale are computed on the specific identification method and are included in earnings on the trade date sold. Equity securities are measured at fair value with changes in the fair value recognized through net income.
Credit Loss, Financial Instrument
Allowance for Credit Losses - Securities: Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type. The Company’s held-to maturity portfolio contains mortgage-backed securities issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses. The Company’s held-to-maturity portfolio also contains municipal bonds that are typically rated by major rating agencies as Aa or better. The Company has never incurred a loss on a municipal bond, therefore the expectation of credit losses on these securities is insignificant. The Company uses industry historical credit loss information adjusted for current conditions to establish the allowance for credit losses on the municipal bond portfolio. The expected credit losses on these bonds are similar to Banner’s commercial business loan portfolio. Therefore, the Company uses the commercial business loan portfolio loss rates to establish the allowance for credit losses on the collateralized bonds and its own loss history to establish a loss rate on bonds that are not collateralized.

For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If the Company intends to sell the security or it is more likely than not that the Company will be required to sell the security before recovering its cost basis, the entire impairment loss would be recognized in earnings.  If the Company does not intend to sell the security and it is not more likely than not that the Company will be required to sell the security, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, Management considers the extent to which fair value is less than amortized costs, any changes to the rating of the security by a rating agency and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security.  Projected cash flows are discounted by the current effective interest rate.  If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. The remaining impairment related to all other factors, the difference between the present value of the cash flows expected to be collected and fair value, is recognized in AOCI.

Changes in the allowance for credit losses are recorded as provision (recapture) for credit losses. Losses are charged against the allowance when Management believes the non-collectability of an available-for-sale or held-to-maturity security is confirmed or when either of the criteria regarding intent or requirement to sell is met.
Investment in FHLB Stock
Investment in FHLB Stock: FHLB stock does not have a readily determinable fair value. The Bank’s investment in FHLB stock is carried at cost or par value ($100 per share) and evaluated for impairment based on the Bank’s expectations of the ultimate recoverability of the stock’s par value. Ownership of FHLB stock is restricted to the FHLB and member institutions and can only be purchased and redeemed at par, therefore there has been no observable changes in market prices. As a member of the FHLB system, the Bank is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding FHLB advances.

Management periodically evaluates FHLB stock for impairment. Management’s determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the client base of the FHLB, and (4) the liquidity position of the FHLB. The Company has determined there is no impairment on the FHLB stock investment as of December 31, 2024 and 2023.
Loans Receivable
Loans Receivable:  The Bank originates one- to four-family residential loans for both portfolio investment and sale in the secondary market.  The Bank also originates construction and land development, multifamily mortgage, commercial real estate, commercial business, agricultural and consumer loans for portfolio investment.  Loans receivable not designated as held for sale are recorded at amortized cost, net of the allowance for credit losses. Amortized cost is the principal amount outstanding, net of deferred fees, discounts and premiums.  Accrued interest on loans is reported in accrued interest receivable on the Consolidated Statements of Financial Condition. Premiums, discounts and deferred loan fees are amortized to maturity using the level-yield methodology.
Finance, Loan and Lease Receivables, Held-for-sale
Loans Held for Sale: One- to four-family residential loans originated with the intent to be sold in the secondary market are considered held for sale. One- to four-family residential loans under best effort delivery commitments are carried at the lower of aggregate cost or estimated market value. One- to four-family residential loans expected to be delivered under mandatory commitments are carried at fair value to match changes in the value of the loans with the value of the related economic hedges on the loans. Fair values for residential mortgage loans held for sale are determined by comparing actual loan rates to current secondary market prices for similar loans. Net unrealized losses on loans held for sale that are carried at lower of cost or market are recognized through the valuation allowance as charges to income.  Non-refundable fees and direct loan origination costs related to loans held for sale carried at the lower of cost or market are recognized as part of the cost basis of the loan. Gains and losses on sales of loans held for sale are determined using the aggregate method and are recorded in the mortgage banking operations component of non-interest income. Non-refundable fees and direct loan origination costs related to loans held for sale carried at the lower of cost or market are recognized as part of the cost basis of the loan.
Acquired Loans Policy
Loans Acquired in Business Combinations: Loans acquired in business combinations are recorded at their fair value at the acquisition date. Establishing the fair value of acquired loans involves a significant amount of judgment, including determining the credit discount based upon historical data adjusted for current economic conditions and other factors. If any of these assumptions are inaccurate, actual credit losses could vary significantly from the credit discount used to calculate the fair value of the acquired loans. Acquired loans are evaluated upon acquisition and classified as either purchased credit-deteriorated or purchased non-credit-deteriorated. Purchased credit-deteriorated (PCD) loans have experienced more than insignificant credit deterioration since origination. For PCD loans, an allowance for credit losses is determined at the acquisition date using the same methodology as other loans held for investment. The initial allowance for credit losses, determined on a collective basis, is allocated to individual loans. A loan’s fair value is grossed up for the allowance for credit losses and becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through a provision (recapture) for credit losses.

For purchased non-credit-deteriorated 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 loan. While credit discounts are included in the determination of the fair value for non-credit-deteriorated loans, since these discounts are expected to be accreted over the life of the loans, they cannot be used to offset the allowance for credit losses that must be recorded at the acquisition date. As a result, an allowance for credit losses is determined at the acquisition date using the same methodology as other loans held for investment and is recognized as a provision for credit losses. Any subsequent deterioration (improvement) in credit quality is recognized by recording a provision (recapture) for credit losses.
Income Recognition on Nonaccrual and Impaired Loans
Income Recognition on Nonaccrual Loans and Securities:  Interest on loans and securities is accrued as earned unless Management doubts the collectability of the asset or the unpaid interest.  Interest accruals on loans are generally discontinued when loans become 90 days past due for payment of interest or principal and the loans are then placed on nonaccrual status.  All previously accrued but uncollected interest is deducted from interest income upon transfer to nonaccrual status.  For any future payments collected, interest income is recognized only upon Management’s assessment that there is a strong likelihood that the full amount of a loan will be repaid or recovered. Management’s assessment of the likelihood of full repayment involves judgment, including determining the fair value of the underlying collateral which can be impacted by the economic environment.  A loan may be put on nonaccrual status sooner than this policy would dictate if, in Management’s judgment, the amounts owed, principal or interest may be uncollectable.  While less common, similar interest reversal and nonaccrual treatment is applied to investment securities if their ultimate collectability becomes questionable.
Provision and Allowance for Loan Losses
Provision and Allowance for Credit Losses - Loans:  The methodology for determining the allowance for credit losses - loans is considered a critical accounting estimate by Management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the economic environment that could result in changes to the amount of the recorded allowance for credit losses - loans. Among the material estimates required to establish the allowance for credit losses - loans are: a reasonable and supportable forecast; a reasonable and supportable forecast period and reversion period; value of collateral; strength of guarantors; the amount and timing of future cash flows for loans individually evaluated; and determination of the qualitative loss factors. All of these estimates are susceptible to significant change. The allowance for credit losses - loans is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. The Company has elected to exclude accrued interest receivable from the amortized cost basis in their estimate of the allowance for credit losses - loans. The provision for credit losses reflects the amount required to maintain the allowance for credit losses - loans at an appropriate level based upon Management’s evaluation of the adequacy of collective and individual loss reserves. The Company has established systematic methodologies for the determination of the adequacy of the Company’s allowance for credit losses - loans. The methodologies are set forth in a formal policy and take into consideration the need for a valuation allowance for loans evaluated on a collective (pool) basis which have similar risk characteristics as well as allowances that are tied to individual loans that do not share risk characteristics.

The Company increases its allowance for credit losses - loans by charging the provision for credit losses. Losses related to specific assets are applied as a reduction of the carrying value of the assets and charged against the allowance for credit loss reserve when Management believes the uncollectibility of a loan balance is confirmed. Recoveries on previously charged off loans are credited to the allowance for credit losses - loans.
Management estimates the allowance for credit losses - loans using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The allowance for credit losses - loans is maintained at a level sufficient to provide for expected credit losses over the life of the loan based on evaluating historical credit loss experience and making adjustments to historical loss information for differences in the specific risk characteristics in the current loan portfolio.  These factors include, among others, changes in the size and composition of the loan portfolio, differences in underwriting standards, delinquency rates, actual loss experience and current economic conditions.

The allowance for credit losses - loans is measured on a collective (pool) basis when similar risk characteristics exist. In estimating the component of the allowance for credit losses for loans that share common risk characteristics, loans are pooled based on loan type and areas of risk concentration. For loans evaluated collectively, the allowance for credit losses is calculated using life of loan historical losses adjusted for economic forecasts and current conditions.

For commercial real estate, multifamily real estate, construction and land and land development, commercial business and agricultural loans with risk rating segmentation, historical credit loss assumptions are estimated using a model that categorizes loan pools based on loan type and risk rating. For one- to four- family residential loans, consumer loans, home equity lines of credit, small business loans, and small balance commercial real estate loans, historical credit loss assumptions are estimated using a model that categorizes loan pools based on loan type and delinquency status. These models calculate an expected life-of-loan loss percentage for each loan category by calculating the probability of default, based on the migration of loans from performing to loss by risk rating or delinquency categories using historical life-of-loan analysis and the severity of loss, based on the aggregate net lifetime losses incurred for each loan pool. For credit cards, historical credit loss assumptions are estimated using a model that calculates an expected life-of-loan loss percentage for each loan category by considering the historical cumulative losses based on the aggregate net lifetime losses incurred for each loan pool.

For loans evaluated collectively, Management uses economic indicators to adjust the historical loss rates so that they better reflect Management’s expectations of future conditions over the remaining lives of the loans in the portfolio based on reasonable and supportable forecasts. These economic indicators are selected based on correlation to the Company’s historical credit loss experience and are evaluated for each loan category. The economic indicators evaluated include the unemployment rate, gross domestic product, real estate price indices and growth, industrial employment, corporate profits, the household consumer debt service ratio, the household mortgage debt service ratio, and single family median home price growth. Management considers various economic scenarios and forecasts when evaluating the economic indicators and weighs the probability of various scenarios to arrive at the forecast that most reflects Management’s expectations of future conditions. The allowance for credit losses is then adjusted for the period in which those forecasts are considered to be reasonable and supportable. To the extent the lives of the loans in the portfolio extend beyond the period for which a reasonable and supportable forecast can be made, the adjustments discontinue to be applied so that the model reverts back to the historical loss rates using a straight-line reversion method. Management selected a reasonable and supportable forecast period of 12 months with a reversion period of 12 months. Both the reasonable and supportable forecast period and the reversion period are periodically reviewed by Management.

Further, for loans evaluated collectively, Management also considers qualitative and environmental factors for each loan category to adjust for differences between the historical periods used to calculate historical loss rates and expected conditions over the remaining lives of the loans in the portfolio. In determining the aggregate adjustment needed, Management considers the financial condition of the borrowers, the nature and volume of the loans, the remaining terms and the extent of prepayments on the loans, the volume and severity of past due and classified loans as well as the value of the underlying collateral on loans in which the collateral dependent practical expedient has not been used. Management also considers the Company’s lending policies, the quality of the Company’s credit review system, the quality of the Company’s management and lending staff, and the regulatory and economic environments in the areas in which the Company’s lending activities are concentrated.

Loans that do not share risk characteristics with other loans in the portfolio are individually evaluated for impairment and are not included in the collective evaluation.  Factors involved in determining whether a loan should be individually evaluated include, but are not limited to, the financial condition of the borrower and the value of the underlying collateral.  Expected credit losses for loans evaluated individually are primarily measured based on the fair market value of the collateral as of the reporting date, less estimated selling costs, as applicable. Under certain circumstances, the Bank may use observable market value of collateral or the present value of the expected future cash flows discounted at the loan’s original effective interest rate. As a practical expedient, the Bank measures the expected credit loss for a loan using the fair value of the collateral, if repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the Bank’s assessment as of the reporting date.

In both cases, if the fair value of the collateral is less than the amortized cost basis of the loan, the Bank will recognize an allowance as the difference between the fair value of the collateral, less costs to sell (if applicable) at the reporting date and the amortized cost basis of the loan. If the fair value of the collateral exceeds the amortized cost basis of the loan, any expected recovery added to the amortized cost basis will be limited to the amount previously charged-off. Subsequent changes in the expected credit losses for loans evaluated individually are included within the provision for credit losses in the same manner in which the expected credit loss initially was recognized or as a reduction in the provision that would otherwise be reported.
Loan Origination and Commitment Fees
Loan Origination and Commitment Fees:  Loan origination fees, net of certain specifically defined direct loan origination costs, are deferred and recognized as an adjustment of the loans’ interest yield using the level-yield method over the contractual term of each loan adjusted for actual loan prepayment experience.  Loan commitment fees are deferred until the expiration of the commitment period unless Management believes there is a remote likelihood that the underlying commitment will be exercised, in which case the fees are amortized to fee income using the straight-line method over the commitment period.  If a loan commitment is exercised, the deferred commitment fee is accounted for in the same manner as a loan origination fee.  Deferred commitment fees associated with expired commitments are recognized as fee income.
Reserve for Unfunded Commitments, Policy
Allowance for Credit Losses - Unfunded Loan Commitments: An allowance for credit losses - unfunded loan commitments is maintained at a level that, in the opinion of Management, is adequate to absorb expected credit losses associated with the contractual life of the Bank’s commitments to lend funds under existing agreements such as letters or lines of credit. The Bank uses a methodology for determining the allowance for credit losses - unfunded loan commitments that applies the same segmentation and loss rate to each pool as the funded exposure adjusted for probability of funding. Draws on unfunded loan commitments that are considered uncollectible at the time funds are advanced are charged to the allowance for credit losses on off-balance sheet exposures. Changes in the allowance for credit losses - unfunded loan commitments are recognized as provision for (or recapture of) credit loss expense and added to the allowance for credit losses - unfunded loan commitments, which is included in other liabilities in the Consolidated Statements of Financial Condition.
Real Estate Held for Sale
Real Estate Owned: Property acquired by foreclosure or deed in-lieu-of foreclosure is recorded at the estimated fair value of the property, less expected selling costs.  Development and improvement costs relating to the property may be capitalized, while other holding costs are expensed.  The carrying value of the property is periodically evaluated by Management and, if necessary, allowances are established to reduce the carrying value to net realizable value.  Gains or losses at the time the property is sold are charged or credited to operations in the period in which they are realized.  The amounts the Bank will ultimately recover from real estate held for sale may differ substantially from the carrying value of the assets because of market factors beyond the Bank’s control or because of changes in the Bank’s strategies for recovering the investment.
Property and Equipment
Property and Equipment:  Property and equipment is carried at cost less accumulated depreciation. Depreciation is based upon the straight-line method applied to individual assets and groups of assets acquired in the same year over the lesser of their estimated useful lives or the related lease terms of the assets, which are as follows:
Buildings and leased improvements
10–39 years
Furniture and equipment
3–10 years

Routine maintenance, repairs and replacement costs are expensed as incurred.  Expenditures which significantly increase values or extend useful lives are capitalized.  The Company reviews buildings, leasehold improvements and equipment for impairment whenever events or changes in circumstances indicate that the undiscounted cash flows for the property are less than its carrying value.  If identified, an impairment loss is recognized through a charge to earnings based on the fair value of the property.

Property is classified as held for sale when the Company commits to a plan to sell the property and is actively marketing the property for sale. Held for sale property is recorded at the lower of the estimated fair value of the property, less expected selling costs, or the book value at the date the property is transferred to held for sale. Depreciation is not recorded on held for sale property.
Schedule of Property and Equipment Useful Lives Depreciation is based upon the straight-line method applied to individual assets and groups of assets acquired in the same year over the lesser of their estimated useful lives or the related lease terms of the assets, which are as follows:
Buildings and leased improvements
10–39 years
Furniture and equipment
3–10 years
Lessee, Leases
Leases: The Company leases retail, office and storage space, and equipment under operating leases. Most leases require the Company to pay real estate taxes, maintenance, insurance and other similar costs in addition to the base rent. Certain leases also contain lease incentives, such as tenant improvement allowances and rent abatement. Variable lease payments are recognized as lease expense as they are incurred. We record an operating lease right of use (ROU) asset and an operating lease liability (lease liability) for operating leases with a lease term greater than 12 months.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Accordingly, ROU assets are reduced by tenant improvement allowances from landlords plus any prepaid rent. We do not separate lease and non-lease components of contracts. As most of our leases do not provide an implicit rate, we generally use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. Many of our leases contain various provisions for increases in rental rates, based either on changes in the published Consumer Price Index or a predetermined escalation schedule which are factored into our determination of lease payments when appropriate. Substantially, all the leases provide the Company with the option to extend the lease term one or more times following expiration of the initial term. The ROU asset and lease liability terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.
Goodwill, Policy Goodwill: Goodwill represents the excess of the purchase consideration paid over the fair value of the assets acquired, net of the fair values of liabilities assumed in a business combination and is not amortized but is reviewed annually or more frequently as current circumstances and conditions warrant, for impairment. The Company completes its annual review of goodwill as of December 31. An assessment of qualitative factors is completed to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The qualitative assessment involves judgment by Management on determining whether there have been any triggering events that have occurred which would indicate potential impairment. If the qualitative analysis concludes that further analysis is required, then a quantitative impairment test would be completed. The quantitative goodwill impairment test is used to identify the existence of impairment and the amount of impairment loss and compares the reporting unit’s estimated fair values, including goodwill, to its carrying amount. If the fair value exceeds the carrying amount, then goodwill is not considered impaired. If the carrying amount exceeds its fair value, an impairment loss would be recognized equal to the amount of excess, limited to the amount of total goodwill allocated to the reporting unit. The impairment loss would be recognized as a charge to earnings. The disposal of a portion of a reporting unit that meets the definition of a business requires goodwill to be allocated for purposes of determining the gain or loss on disposal
Other Intangible Assets
Other Intangible Assets:  Other intangible assets consist primarily of core deposit intangibles (CDI) which are amounts recorded in business combinations or deposit purchase transactions related to the value of transaction-related deposits and the value of the client relationships associated with the deposits.  CDI is being amortized on an accelerated basis over a weighted average estimated useful life of eight to 10 years.  These assets are reviewed at least annually for events or circumstances that could impact their recoverability.  These events could include loss of the underlying core deposits, increased competition or adverse changes in the economy.  To the extent other identifiable intangible assets are deemed unrecoverable, impairment losses are recorded in other non-interest expense to reduce the carrying amount of the assets.
Mortgage Servicing Rights
Mortgage and Small Business Administration (SBA) Servicing Rights: Servicing assets are recognized as separate assets when rights are acquired through purchase or sale of loans.  Generally, purchased servicing rights are capitalized at the cost to acquire the rights.  For sales of mortgage and SBA loans, the fair value of the servicing right is estimated and capitalized.  Fair values are estimated based on an independent dealer analysis of discounted cash flows. Capitalized mortgage servicing rights are reported in other assets and are amortized into mortgage banking operations in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Capitalized SBA servicing rights are reported in other assets and are carried at fair value. Changes in the fair value of SBA servicing rights are recognized into miscellaneous non-interest income.

Mortgage servicing assets are evaluated for impairment based upon the fair value of the rights as compared to amortized cost.  Impairment is determined by stratifying rights into tranches based on predominant risk characteristics for the underlying loans, such as interest rate, balance outstanding, loan type, age and remaining term, and investor type.  Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranche.  If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income.

Servicing fee income is recorded for fees earned for servicing loans. Servicing fee income is reflected in mortgage banking operations for mortgage servicing rights and in miscellaneous non-interest income for SBA servicing rights on the Consolidated Statements of Operations.  The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned.  The amortization of mortgage servicing rights is netted against loan servicing fee income.
Bank-Owned Life Insurance (BOLI) Bank-Owned Life Insurance:  The Bank has purchased, or acquired through mergers, life insurance policies in connection with the implementation of certain executive supplemental income, salary continuation and deferred compensation retirement plans.  These policies provide protection against the adverse financial effects that could result from the death of a key employee and provide tax-exempt income to offset expenses associated with the plans.  It is the Bank’s intent to hold these policies as a long-term investment; however, there may be an income tax impact if the Bank chooses to surrender certain policies.  Although the lives of individual, current or former management-level employees are insured, the Bank is the respective owner and sole or partial beneficiary. BOLI is carried at the cash surrender value (CSV) of the underlying insurance contract. Changes in the CSV and any death benefits received in excess of the CSV are recognized as non-interest income.
Derivative Instruments
Derivative Instruments:  Derivatives include “off-balance-sheet” financial products, the value of which is dependent on the value of underlying financial assets, such as stock, bonds, foreign currency, or a reference rate or index.  Such derivatives include “forwards,” “futures,” “options” or “swaps.”  The Bank used an interest rate swap program which involves the receipt of fixed-rate amounts from a counterparty in exchange for variable-rate payments over the life of the agreements without exchange of the underlying notional amount. Such derivatives were used to hedge the variable cash flows associated with existing variable-rate assets. These interest rate swaps qualified as cash flow hedging instruments so gains and losses were recorded in AOCI to the extent the hedge was effective. Gains and losses on the interest rate swaps were reclassified from AOCI to earnings in the period the hedged transaction affected earnings and were included in interest income. Amounts reported in AOCI related to derivatives were reclassified to interest income as interest payments were received on the Company’s variable-rate assets. The related cash flows were recognized as cash flows from operating activities on the Consolidated Statement of Cash Flows. These cash flow hedges matured in 2024.

The Bank offers an interest rate swap program for commercial loan clients that provides the client with a variable-rate loan and enters into an interest rate swap allowing them to effectively fix their loan interest rates.  These client swaps are matched with third party swaps with qualified broker/dealer or banks to offset the risk.  The fair value adjustments for these swaps are recorded in either other assets or other liabilities, as appropriate.
Further, as a part of its mortgage banking activities, the Company issues “rate lock” commitments to one- to four-family loan borrowers and obtains offsetting “best efforts” delivery commitments from purchasers of loans. The Company uses forward contracts for the sale of mortgage-backed securities and mandatory delivery commitments for the sale of loans to hedge one- to four-family loan “rate lock” commitments and one- to four-family residential loans held for sale.  The commitments to originate mortgage loans held for sale and the related delivery contracts are considered derivatives.  The Company recognizes all derivatives as either assets or liabilities in the balance sheet and requires measurement of those instruments at fair value through adjustments to current earnings.  None of these residential mortgage loan related derivatives are designated as hedging instruments for accounting purposes.  Rather, they are accounted for as free-standing derivatives, or economic hedges, and the Company reports changes in fair values of its derivatives in current period net income.  The fair values for these instruments, which generally change as a result of changes in the level of market interest rates, are estimated based on dealer quotes and secondary market sources.  Assumptions used include rate assumptions based on historical information, current mortgage interest rates, the stage of completion of the underlying application and underwriting process, the time remaining until the expiration of the derivative loan commitment, and the expected net future cash flows related to the associated servicing of the loan.
Transfers of Financial Assets
Transfers of Financial Assets:  Transfers of financial assets are accounted for as sales when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Bank, (2) the transferee has the right to pledge or exchange the transferred assets beyond a trivial benefit, and (3) the Bank does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Income Taxes
Income Taxes:  The Company files a consolidated income tax return including all of its wholly-owned subsidiaries on a calendar year basis.  Income taxes are accounted for using the asset and liability method.  Under this method, a deferred tax asset or liability is determined based on the enacted tax rates which are expected to be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company’s income tax returns.  The effect on deferred taxes of a change in tax rates is recognized in income in the period of change. A valuation allowance is recognized as a reduction to deferred tax assets when Management determines it is more likely than not that deferred tax assets will not be available to offset future income tax liabilities.

Accounting standards for income taxes prescribe a recognition threshold and measurement process for financial statement recognition and measurement of uncertain tax positions taken or expected to be taken in a tax return, and provides guidance on the de-recognition of previously recorded benefits and their classification, as well as the proper recording of interest and penalties, accounting in interim periods, disclosures and transition.  The Company periodically reviews its income tax positions based on tax laws and regulations and financial reporting considerations, and records adjustments as appropriate.  This review takes into consideration the status of current taxing authorities’ examinations of the Company’s tax returns, recent positions taken by the taxing authorities on similar transactions, if any, and the overall tax environment.
Share-Based Compensation
Stock-Based Compensation:  Under the Company’s stock-based incentive plans, the Company compensates employees and directors with time-based restricted stock and restricted stock unit grants. Some restricted stock awards include performance-based and market-based goals that impact the number of shares that ultimately vest based on the level of goal achievement. The Company measures the cost of employee or director services received in exchange for an award of equity instruments based on the fair value of the award, which is the intrinsic value on the grant date. This cost is recognized as expense in the Consolidated Statements of Operations ratably over the vesting period of the award with forfeitures of nonvested awards recognized as they occur. Any tax benefit or deficiency is recorded as income tax benefit or expense in the period the shares vest. Excess tax benefits are classified, along with other income tax cash flows, as an operating activity. The Company issues restricted stock and restricted stock unit awards which vest over a one- or three-year period during which time, the employee or director accrues or receives dividends and may have full voting rights depending on the terms of the grant.
Earnings Per Share, Policy
Earnings Per Share: Earnings per common share is computed under the two-class method. Pursuant to the two-class method, non-vested stock-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents are participating securities and are included in the computation of earnings per share. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Application of the two-class method resulted in the equivalent earnings per share to the treasury method.

Basic earnings per common share is computed by dividing net earnings allocated to common shareholders by the weighted average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Diluted earnings per common share is computed using the weighted average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock compensation, using the treasury stock method.
Comprehensive Income
Comprehensive Income:  Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income.  In addition, certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, unrealized gains and losses on interest rate swaps used in cash flow hedges and changes in fair value of junior subordinated debentures related to instrument specific credit risk, are reported as a separate component of the equity section of the Consolidated Statements of Financial Condition, and such items, along with net income, are components of comprehensive income which is reported in the Consolidated Statements of Comprehensive Income.

Reclassification: Certain reclassifications have been made to the prior years’ consolidated financial statements and/or schedules to conform to the current year’s presentation. These reclassifications may have an impact on certain reported amounts and ratios for the prior periods. These reclassifications had no effect on retained earnings or net income as previously presented and the effect of these reclassifications is considered immaterial.
