Summary of Significant Accounting Policies

Nature of Operations-Columbia Banking System, Inc. is headquartered in Tacoma, Washington, and is engaged primarily in the business of commercial and consumer banking. The Company provides a broad range of banking and other financial services to corporate, institutional, small business, and individual customers through its wholly-owned banking subsidiary Umpqua Bank. The Bank has a wholly-owned subsidiary, Financial Pacific Leasing, Inc., which is a commercial equipment leasing company.

The Company and its subsidiaries are subject to regulation by certain federal and state agencies and undergo periodic examination by these regulatory agencies.

Basis of Financial Statement Presentation-On February 28, 2023, UHC merged with and into Columbia, with Columbia continuing as the surviving legal corporation. Promptly following the Merger, Columbia’s wholly-owned bank subsidiary, Columbia State Bank, merged with and into UHC’s wholly-owned bank subsidiary, Umpqua Bank, with Umpqua Bank as the surviving bank. Upon completion of the Merger, the combined company became Columbia Banking System, Inc. (together with its direct and indirect subsidiaries, "we," "us," "our," "Columbia" or the "Company"), which is a financial holding company with its wholly-owned banking subsidiary Umpqua Bank (the "Bank").

The Merger was accounted for as a reverse merger using the acquisition method of accounting; therefore, UHC was deemed the acquirer for financial reporting purposes, even though Columbia was the legal acquirer. The Merger was effectively an all-stock transaction and was accounted for as a business combination. Columbia's financial results for any periods ended prior to February 28, 2023, the Merger Date, reflect UHC results only on a standalone basis. Accordingly, Columbia's reported financial results for the three months ended March 31, 2023 reflect only UHC financial results through the closing of the Merger and may not be directly comparable to the prior or future reported periods. The number of shares issued and outstanding, earnings per share, additional paid-in capital, and all references to share quantities or metrics of Columbia have been retrospectively restated to reflect the equivalent number of shares issued in the Merger as the Merger was accounted for as a reverse acquisition using the acquisition method of accounting. Under the reverse acquisition method of accounting, the assets and liabilities of Columbia were recorded at their respective fair values as of February 28, 2023 ("historical Columbia"). Refer to Note 2 – Business Combination for additional information on this acquisition.

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and with prevailing practices within the banking and securities industries. In preparing such financial statements, management is required to make certain estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the balance sheet and the reported amounts of revenues and expenses for the reporting period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the ACL and goodwill.

Consolidation-The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, and the Bank's wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The Company has wholly-owned trusts that were formed to issue trust preferred securities and related common securities of the Trusts. The Company has not consolidated the accounts of the Trusts in its consolidated financial statements as they are considered to be variable interest entities for which the Company is not a primary beneficiary. As a result, the junior subordinated debentures issued by the Company to the Trusts are reflected on the Company's Consolidated Balance Sheets as junior subordinated debentures.

Subsequent events-The Company has evaluated events and transactions through the date that the consolidated financial statements were issued for potential recognition or disclosure.

Business Combinations-The Company applies the acquisition method of accounting for business combinations. Under the acquisition method, the acquiring entity recognizes the assets acquired and liabilities assumed at their acquisition date fair values. Management utilizes prevailing valuation techniques appropriate for the asset or liability being measured in determining these fair values. This method often involves estimates based on third-party valuations or internal valuations based on discounted cash flow analyses or other valuation techniques, all of which are inherently subjective. Any excess of the purchase price over the fair value of net assets and other identifiable intangible assets acquired is recorded as goodwill. Assets acquired and liabilities assumed from contingencies must also be recognized at fair value if the fair value can be determined during the measurement period. Acquisition‑related costs, including conversion and restructuring charges, are expensed as incurred. Fair values are subject to refinement over the measurement period, not to exceed one year after the closing date.

Cash and Cash Equivalents-Cash and cash equivalents include cash and due from banks and temporary investments which are interest-bearing balances due from other banks. Cash and cash equivalents generally have a maturity of 90 days or less at the time of purchase.

Equity and Other Securities-Equity and other securities are carried at fair value with realized and unrealized gains or losses recorded in non-interest income.

Investment Securities Available for Sale-Debt securities are classified as available for sale if the Company intends and has the ability to hold those securities for an indefinite period of time, but not necessarily to maturity. Any decision to sell a debt security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors. Premiums and discounts are amortized or accreted over the life of the related investment security as an adjustment to yield using the effective interest method. Dividend and interest income are recognized when earned.

Securities available for sale are carried at fair value. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings. Unrealized holding gains or losses are included in other comprehensive income as a separate component of shareholders' equity, net of tax. When the fair value of an available-for-sale debt security falls below the amortized cost basis, it is evaluated to determine if any of the decline in value is attributable to credit loss. Decreases in fair value attributable to credit loss would be recorded directly to earnings with a corresponding ACL, limited by the amount that the fair value is less than the amortized cost basis. If the credit quality subsequently improves, the allowance would be reversed up to a maximum of the previously recorded credit losses. If the Company intends to sell an impaired available-for-sale debt security, or if it is more likely than not that the Company will be required to sell the security prior to recovering the amortized cost basis, the entire fair value adjustment would be immediately recognized in earnings with no corresponding ACL.

Loans Held for Sale-Loans held for sale represent residential mortgage loans intended to be sold in the secondary market and non-mortgage loans that management has an active plan to sell. The Company has elected to account for residential mortgage loans held for sale at fair value and non-mortgage loans at the lower of cost or fair value. Fair value is determined based on quoted secondary market prices for similar loans, including the implicit fair value of embedded servicing rights. The change in fair value of loans held for sale is primarily driven by changes in interest rates subsequent to loan funding, resulting in revaluation adjustments to the recorded fair value. The inputs used in the fair value measurements are considered Level 2 inputs. The use of the fair value option allows the change in the fair value of loans to more effectively offset the change in the fair value of derivative instruments that are used as economic hedges to loans held for sale. Loan origination fees and direct origination costs are recognized immediately in net income. Interest income on loans held for sale is included in interest income on the Consolidated Statements of Income and recognized when earned. Loans held for sale are placed on non-accrual in a manner consistent with loans held for investment. The Company recognizes the gain or loss on the sale of loans when the sales criteria for derecognition are met.

Loans and Leases-Loans are stated at the amount of unpaid principal, net of unearned income and any deferred fees or costs. All discounts and premiums are recognized over the contractual life of the loan as yield adjustments. Origination and commitment fees and direct loan origination costs for loans and leases held for investment are deferred and recognized as an adjustment to the yield over the life of the loans and leases. The recognition of these net deferred fees is accelerated at loan payoff, if earlier than the life of the loan.

Leases are recorded at the amount of minimum future lease payments receivable and estimated residual value of the leased equipment, net of unearned income and any deferred fees. Initial direct costs related to lease originations are deferred as part of the investment in direct financing leases and amortized over their term using the effective interest method. Unearned lease income is amortized over the lease term using the effective interest method.

Loans and leases purchased or acquired through business combinations without more-than-insignificant credit deterioration are recorded at their fair value at the acquisition date. However, loans and leases purchased with more-than-insignificant credit deterioration will be recorded with their applicable ACL to determine the amortized cost basis. The difference between the fair value and principal balance is recognized as an adjustment to the yield over the remaining life of the loan and lease. The Company periodically sells loans through either securitizations or individual loans sales from its portfolio to maintain a balanced and healthy loan portfolio, enhance liquidity, and manage credit risk.

Non-Accrual and Past Due Loans and Leases-Loans and leases are considered past due when the contractual amounts due with respect to principal and interest are not received within 30 days of the contractual due date. Loans are classified as non-accrual if the collection of principal and interest is doubtful. Generally, this occurs when a loan is past due beyond its maturity, principal payment, or interest payment due date by 90 days or more, unless such loans are well-secured and in the process of collection. Loans that are less than 90 days past due may also be classified as non-accrual if repayment in full of principal and/or interest is in doubt.

Generally, when a loan is classified as non-accrual, all uncollected accrued interest is reversed from interest income and the accrual of interest income is discontinued. In addition, any cash payments subsequently received are applied as a reduction of principal outstanding. In cases where the future collectability of the principal balance in full is expected, interest income may be recognized on a cash basis. A loan may be restored to accrual status when the borrower's financial condition improves so that full collection of future contractual payments is considered likely. For those loans placed on non-accrual status due to payment delinquency, return to accrual status will typically not occur until the borrower demonstrates repayment ability over a period of not less than six months.

Modifications to Borrowers Experiencing Financial Difficulty-A debtor is considered to be experiencing financial difficulty when there is significant doubt about the debtor’s ability to make required payments on the debt or to get equivalent financing from another creditor at a market rate for similar debt. The Company may modify the contractual terms of loans and leases to a borrower experiencing financial difficulties as a way to mitigate loss, proactively work with borrowers in financial difficulty, or to comply with regulations regarding the treatment of certain bankruptcy filing and discharge situations.

Modifications to borrowers in financial difficulty may include term extensions, interest rate reductions, principal or interest forgiveness, an other-than-insignificant payment delay, or any combination of these. The Company closely monitors the performance of loans and leases that are modified for borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. Loans and leases are considered to be in payment default at 90 days or more days past due. Loans and leases with modifications to borrowers experiencing financial difficulty are subject to policies governing accrual/non-accrual evaluation consistent with all other loans of the same product types. As such, modifications to troubled borrowers may include loans remaining on non-accrual, moving to non-accrual, or continuing on accrual status, depending on the individual facts and circumstances.

Allowance for Credit Losses-ASC Topic 326 requires an expected loss model, which encompasses allowances for credit losses expected to be incurred over the contractual life of loans measured at amortized cost, including unfunded commitments. The estimate of current expected credit losses is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. To calculate the ACL, management uses models to estimate the PD and LGD for loans, utilizing inputs that include forecasted future economic conditions and specific macroeconomic variables relevant to each of the Bank’s loan and lease portfolios. Moody's Analytics, a third party, supplies the historical and forward-looking macroeconomic data utilized in the models used to calculate the ACL.

The Company utilizes complex models to obtain reasonable and supportable forecasts. Most of the models calculate two predictive metrics: the PD and LGD. The PD measures the probability that a loan will default within a given time horizon and primarily measures the adequacy of the debtor's cash flow as the primary source of repayment of the loan or lease. The LGD is the expected loss which would be realized presuming a default has occurred and primarily measures the value of the collateral or other secondary sources of repayment related to the collateral. Acquired and newly originated loans and leases that have not been modeled receive a loss rate via an extrapolated rate methodology.

Historical loss experience is the starting point for estimating expected credit losses. Adjustments are made to historical loss experience to reflect differences in asset-specific risk characteristics, such as underwriting standards, portfolio mix or asset terms, and differences in economic conditions – both current conditions and reasonable and supportable forecasts. When the Company is not able to make or obtain reasonable and supportable forecasts for the entire life of the financial asset, it has estimated expected credit losses for the remaining life using an approach that reverts to historical credit loss information for the longer-term portion of the asset's life. The allowance related to the extrapolated population is based on loan segment, PD credit classification, and vintage year of the modeled loans and leases. A loss factor is calculated and applied to the non-modeled loans and leases.

In calculating the ACL, the Bank considered the financial and economic environment at the time of assessment and economic scenarios that differed in the levels of severity and sensitivity to the ACL results. At each measurement date, the Bank selects the scenario that reflects its view of future economic conditions and is determined to be the most probable outcome. All forecasts are updated for each variable where applicable and incorporated as relevant into the ACL calculation. Actual credit loss results and the timing thereof will differ from the estimate of credit losses, either in a strong economy or a recession, as the portfolio will change through time due to growth, risk mitigation actions and other factors. In addition, the scenarios used will differ and change through time as economic conditions change. Economic scenarios might not capture deterioration or improvement in the economy timely enough for the Bank to be able to adequately address the impact to the ACL.

The ACL is measured on a collective (pool) basis when similar characteristics exist. The Company has selected models at the portfolio level using a risk-based approach, with larger, more complex portfolios having more complex models. Except as noted below, the macroeconomic variables that are inputs to the models are reasonable and supportable over the life of the loans in that they reasonably project the key economic variables in the near term and then converge to a long-run equilibrium trend. These models produce reasonable and supportable estimates of loss over the life of the loans as the projected credit losses will also converge to a steady state in line with the variables applied.

The following provides credit quality indicators and risk elements most relevant in monitoring and measuring the ACL on loans for each of the loan portfolio segments identified:

•Commercial Real Estate: Non-owner occupied commercial real estate, multifamily, and commercial construction loans are analyzed using a model that uses four primary property variables: net operating income, property value, property type, and location. For PD estimation, the model simulates potential future paths of net operating income given commercial real estate market factors determined from macroeconomic and regional commercial real estate forecasts. Using the resulting expected debt service coverage ratios, together with predicted loan-to-values and other variables, the model estimates PD from the range of conditional possibilities. In addition, the model estimates maturity PD capturing refinance default risk to produce a total PD for the loan. The model estimates LGD, inclusive of principal loss and liquidation expenses, empirically using predicted loan-to-value as well as certain market and other factors. The LGD calculation also includes a separate maturity risk component. The primary economic drivers in the model are GDP growth, U.S. unemployment rate, and 10-Year Treasury yield. These economic drivers are translated into a forecast, provided by Moody's Analytics' REIS, of real estate metrics, such as rental rates, vacancies, and cap rates. The model produces PD and LGD on a quarter-by-quarter basis for the life of loan.

The owner-occupied commercial real estate portfolio utilizes a top-down macroeconomic model using logistic regression. This model produces portfolio level quarterly net charge-off rates according to the macroeconomic scenario over a reasonable and supportable two-year forecast. The primary economic drivers for this model are commercial real estate price index and a five-state average unemployment rate. The model utilizes output reversion methodology, which after two years reverts on a straight-line basis over one year to the long run historical average net charge-off rate.

•Commercial: Non-homogeneous commercial loans and leases and residential development loans are analyzed in a multi-step process. An initial PD is estimated using a model driven by an obligor's selected financial statement ratios, together with cycle-adjusting information based on the obligor's state and industry. An initial LGD is derived separately based on collateral type using collateral value and a haircut to reflect the loss in liquidation. Another model then applies an auto-regression technique to the initial PD and LGD metrics to estimate the PD and LGD curves according to the macroeconomic scenario. The primary economic drivers in the model are GDP growth and commercial real estate price index.

The model for the homogeneous lease and equipment finance agreement portfolio uses lease and equipment finance agreement information, such as origination and performance, as well as macroeconomic variables to calculate PD and LGD values. The PD calculation is based on survival analysis while LGD is calculated using a two-step regression. The model calculates LGD using an estimate of the probability that a defaulted lease or equipment finance agreement will have a loss, and an estimate of the loss amount. The primary economic drivers for the model are U.S. unemployment rate, the 5-year treasury rate, value of construction put in place, consumer price index, and a home price growth index. The model produces PD and LGD curves at the lease or equipment finance agreement level for each month in the forecast horizon.

•Residential: The models for residential real estate and HELOCs utilize loan level variables, such as origination and performance, as well as macroeconomic variables to calculate PD and LGD. The U.S. unemployment rate and home price growth rate indexes are primary economic drivers in both the residential real estate and HELOC models. In addition, the prime rate is also a primary driver in the HELOC model. The models focus on establishing an empirical relationship between default probabilities and a set of loan-level, borrower, and macroeconomic credit risk drivers. The LGD calculation for residential real estate is based on an estimate of the probability that a defaulted loan will have a loss, and then an estimate of the loss amount. HELOCs utilize the same model using residential real estate LGD values to assign loans to cohorts based on FICO scores and loan age. The model produces PD and LGD curves at the loan level for each quarter in the forecast horizon.

•Consumer: Historical net charge-off information as well as economic assumptions are used to project loss rates for the Consumer segment.

Loans and leases that have not been included in the models based on portfolio type are assigned a loss rate through an extrapolation methodology. This methodology applies to certain loans acquired through mergers, newly originated loans and leases, and those lacking the detailed data required for the primary models. The extrapolation methodology involves calculating loss rates through the modeling process. These loss rates are determined based on the vintage year, credit classification, and reporting category of the loans and leases. The calculated loss factors are then applied to the excluded loans and leases and evaluated qualitatively to ensure reasonability and compliance with CECL.

Along with the quantitative factors, qualitative factors are also considered in determining the ACL. Qualitative factors are used to capture characteristics in the portfolio that impact expected credit losses but are not fully captured within the expected credit loss models. These factors may include adjustments for changes in policies, procedures, personnel, and unforeseen events affecting key inputs and assumptions within the Bank’s expected credit loss models.

Loss factors from the models, prepayment speeds, and qualitative factors are input into the Company's CECL accounting application, which aggregates the information. The Company then uses two methods to calculate the current expected credit loss: 1) the DCF method, which is used for all loans except lines of credit and 2) the non-DCF method, which is used for lines of credit due to the difficulty of calculating an effective interest rate when lines have yet to be drawn on. The DCF method utilizes the effective interest rate of individual assets to discount the expected credit losses adjusted for prepayments. The difference in the net present value and the amortized cost of the asset will result in the required allowance. The non-DCF method uses the exposure at default, along with the expected credit losses adjusted for prepayments to calculate the required allowance.

Typically, loans in a non-accrual status will not have an ACL as they will be written down to their net realizable value or charged-off. However, the net realizable value for homogeneous leases and equipment finance agreements is determined by the LGD calculated by the CECL model and therefore leases and equipment finance agreements on non-accrual will have an ACL until they become 181 days past due, at which time they are charged-off. The Bank has elected to exclude accrued interest receivable from the measurement of its ACL given the well-defined non-accrual policies which results in timely reversal of outstanding interest through interest income.

Fluctuations in the allowance are reported in the Consolidated Statements of Income as a component of provision for credit losses. Loans are charged-off against the allowance when deemed uncollectible by management. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off.

The Bank has established an Allowance for Credit Losses Committee, which is responsible for, among other things, regularly reviewing the ACL methodology, including allowance levels, and ensuring that it is designed and applied in accordance with generally accepted accounting principles. There is, however, no assurance that future loan losses will not exceed the levels provided for in the ACL and could possibly result in additional charges to the provision for credit losses.

Collateral-Dependent Loan-A loan or lease is considered collateral dependent when repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty. The Company's classification of CDLs includes: non-homogeneous non-accrual loans and leases; non-homogeneous loans and leases determined by individual credit review; homogeneous non-accrual leases and equipment finance agreements; and homogeneous real estate secured loans that have been charged down to net realizable value or the government guaranteed balance. Except for homogeneous leases and equipment finance agreements, the expected credit losses for CDLs will be measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable, less the amortized cost basis of the financial asset. The Company may also use the loan's observable market price, if available. If the value of the CDL is determined to be less than the recorded amount of the loan, a charge-off will be taken. To determine the expected credit loss for homogeneous leases or equipment finance agreements, the LGD calculated by the CECL model will be utilized. When a homogeneous lease or equipment finance agreement becomes 181 days past due, it is fully charged-off.

Reserve for Unfunded Commitments-A RUC is maintained at a level that, in the opinion of management, is adequate to absorb expected losses associated with the Bank's commitment to lend funds under existing agreements, such as letters or lines of credit. The RUC calculation utilizes the ACLLL rates by segment, and utilization rates based on the economic expectations over the contractual life of the commitment adjusted for qualitative considerations, if necessary. The reserve is based on estimates and ultimate losses may vary from the current estimates. These estimates are evaluated on a regular basis and adjustments are reported in earnings in the periods in which they become known. Draws on unfunded commitments that are considered uncollectible at the time funds are advanced are charged to the allowance for credit losses on loans and leases. Provisions for unfunded commitment losses are added to the RUC, which is included in the other liabilities section of the Consolidated Balance Sheets.

Restricted Equity Securities-Restricted equity securities consists mostly of the Bank's investment in Federal Home Loan Bank of Des Moines stock that is carried at par value, which reasonably approximates its fair value. As a member of the FHLB system, the Bank is required to maintain a minimum level of investment in FHLB stock based on a specific percentage of total assets, with additional stock requirements based on use of FHLB products. The Bank may request redemption at par value of any stock in excess of the minimum required investment. Stock redemptions are at the discretion of the FHLB.

Premises and Equipment-Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is allocated over the estimated useful life of equipment, generally three to ten years, and premises, up to 39 years, on a straight-line or accelerated basis. Generally, leasehold improvements are amortized or accreted over the life of the related lease, or the life of the related asset, whichever is shorter. Expenditures for major renovations and betterments of the Company's premises and equipment are capitalized. The Company purchases, as well as internally develops and customizes, certain software to enhance or perform internal business functions. Software development costs incurred in the preliminary project stages are charged to non-interest expense. Costs associated with designing software configuration, installation, coding programs and testing systems are capitalized and amortized using the straight-line method over three to seven years. Implementation costs incurred for software that is part of a hosting arrangement are capitalized in other assets and amortized on a straight-line basis over the life of the contract. In addition to annual impairment reviews, management reviews long-lived assets anytime a change in circumstance indicates the carrying amount of these assets may not be recoverable.

Operating Leases-The Company leases branch locations, corporate office space, and equipment under non-cancelable leases. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The leases contain various provisions for increases in rental rates, based either on changes in the published Consumer Price Index or a predetermined escalation schedule. Substantially all of the leases provide the Company with one or more options to renew, with renewal terms that can extend the lease term from one to ten years or more. The exercise of lease renewal options is at management's sole discretion. The depreciable life of assets and leasehold improvements are limited by the expected lease term unless there is a transfer of title or purchase option reasonably certain of exercise. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company rents or subleases certain real estate to third parties. The Company's sublease portfolio consists of operating leases of mainly former branch locations or excess space in branch or corporate facilities. In addition to annual impairment reviews, management reviews right of use assets anytime a change in circumstances indicates the carrying amount of these assets may not be recoverable.

Operating Segments-Operating segments are components of a business for which separate financial information is available and regularly evaluated by the CODM to allocate resources and assess performance. The Company must report information about its operating segment in financial statements, including details about products and services, geographic activities, and major customers. The Company’s CODM manages and evaluates financial performance on a company-wide basis. As such, the Company has determined it has one reportable segment.

Goodwill and Other Intangibles-Intangible assets are comprised of goodwill and other intangibles acquired in business combinations. Goodwill is not amortized but instead is periodically tested for impairment. The Company performs a goodwill impairment analysis on an annual basis as of October 31 or whenever events or changes in circumstances indicate the carrying value may not be recoverable. Goodwill is assessed for impairment at the reporting unit level either qualitatively or quantitatively. A significant amount of judgment is involved in determining if an indicator of impairment has occurred.

Intangible assets with definite useful lives are amortized to their estimated residual values over their respective estimated useful lives, and also reviewed for impairment whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Amortization of intangible assets is included in non-interest expense on the Consolidated Statements of Income.

Mortgage Servicing Rights-The Company determines its classes of servicing assets based on the asset type being serviced along with the methods used to manage the risk inherent in the servicing assets, which includes the market inputs used to value servicing assets. Fair value adjustments encompass market-driven valuation changes and the runoff in value that occurs from the passage of time, which are separately disclosed. Under the fair value method, the MSR is carried in the balance sheet at fair value and the changes in fair value are reported in earnings under the caption residential mortgage banking revenue, net in the period in which the change occurs.

The expected life of the loans underlying the MSR can vary from management's estimates due to prepayments by borrowers, especially when rates change significantly. Prepayments outside of management's estimates would impact the recorded value of the residential MSR. The value of the MSR is also dependent upon the discount rate used in the model, which management reviews on an ongoing basis. An increase in the discount rate would reduce the value of the MSR.

Revenue Recognition-The Company's revenue within the contracts with customers guidance are presented within non-interest income and include service charges on deposits, card-based fees, merchant fee income, and financial services, brokerage revenue and trust revenue. These revenues are recognized when obligations under the terms of a contract with customers are satisfied. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. When the amount of consideration is variable, the Company will only recognize revenue to the extent that it is probable that the cumulative amount recognized will not be subject to a significant reversal in the future. Substantially all of the Company's contracts with customers have expected durations of one year or less and payments are typically due when or as the services are rendered or shortly thereafter. When third parties are involved in providing services to customers, the Company recognizes revenue on a gross basis when it has control over those services being provided to the customer; otherwise, revenue is recognized for the net amount of any fee or commission.

Revenue is segregated based on the nature of product and services offered as part of contractual arrangements. Revenue from contracts with customers is broadly segregated as follows:

•Service charges on deposits consist primarily of fees earned from deposit customers for account maintenance and transaction-based and overdraft services. Account maintenance fees consist primarily of account fees and analyzed account fees charged on deposit accounts on a monthly basis. The performance obligation is satisfied, and the fees are recognized on a monthly basis as the service period is completed. Transaction-based fees on deposit accounts are charged to deposit customers for specific services provided to the customer, such as non-sufficient funds fees, overdraft fees, and wire fees. The performance obligation is completed as the transaction occurs and the fees are recognized at the time each specific service is provided to the customer.

•Card-based fees are comprised of debit and credit card income, ATM fees, and merchant services income. Debit and credit card income is primarily comprised of interchange fees earned when the Bank's customers' debit and credit cards are processed through card payment networks. The performance obligation is satisfied, and the fees are earned when the cost of the transaction is charged to the cardholders' debit or credit card. Certain expenses and rebates directly related to the credit and debit card interchange contract are recorded on a net basis with the interchange income.

•Financial services and trust revenue consists of brokerage revenue related to third-party revenue share agreements for commissions on brokerage services and trust revenue from trust administration and investment management services. Brokerage revenue is recognized when cash payment is received by the third party based on the net revenues earned on the products and services purchased in the month prior. Trust revenue is recognized monthly and based on the portfolio values at the end of the prior month.

•Other non-interest income includes a variety of other revenue streams including residential mortgage banking, net revenue, security gains and losses, loan sales gain and losses, BOLI income revenue, swap revenue, treasury management, and miscellaneous consumer fees. These revenue streams are not in the scope of revenue from contracts with customers guidance. Revenue is recognized when, or as, the performance obligation is satisfied. Inherent variability in the transaction price is not recognized until the uncertainty affecting the variability is resolved.

Income Taxes-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 will 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 that includes the enactment date. Valuation allowances are established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not, that all or some portion of the potential deferred tax asset will not be realized.

Deferred tax assets are recognized subject to management's judgment that realization is "more likely than not." Uncertain tax positions that meet the "more likely than not" recognition threshold are measured to determine the amount of benefit to recognize. An uncertain tax position is measured at the amount of benefit that management believes has a greater than 50% likelihood of realization upon settlement.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the DTA will or will not be realized. The Company's ultimate realization of the DTA is dependent upon the generation of future taxable income during the periods in which temporary differences become deductible. Management considers the nature and amount of historical and projected future taxable income, the scheduled reversal of deferred tax assets and liabilities, and available tax planning strategies in making this assessment. The amount of deferred taxes recognized could be impacted by changes to any of these variables.

The Company earns Investment Tax Credits on certain equipment leases and uses the deferral method to account for these tax credits. Under this method, the Investment Tax Credits are recognized as a reduction of depreciation expense over the life of the asset.

Derivatives-The Bank enters into forward delivery contracts to sell residential mortgage loans or mortgage-backed securities to broker/dealers at specific prices and dates in order to hedge the interest rate risk in its portfolio of mortgage loans held for sale and its residential mortgage loan commitments. The commitments to originate mortgage loans held for sale and the related forward delivery contracts are considered derivatives. The Bank also executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are hedged by simultaneously entering into an offsetting interest rate swap that the Bank executes with a third party, such that the Bank minimizes its net risk exposure. The Bank also uses certain derivative financial instruments to offset changes in the value of its MSR. These derivatives consist primarily of interest rate futures and forward settling mortgage-backed securities. The Company considers all free-standing derivatives as economic hedges and recognizes these derivatives as either assets or liabilities in the balance sheet, and the Company requires measurement of those instruments at fair value through adjustments to current earnings. None of the Company's derivatives are designated as hedging instruments.

The fair value of the derivative residential mortgage loan commitments is estimated using the net present value of expected future cash flows. Assumptions used include pull-through rate assumption based on historical information, current mortgage interest rates, the stage of completion of the underlying application and underwriting process, direct origination costs yet to be incurred, 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.

Stock-Based Compensation-The Company recognizes expense in its statement of income for the grant-date fair value of RSUs and RSAs issued over the requisite service period, which is generally the vesting period. Estimated forfeitures are included in the calculation of stock-based compensation expense, with actual forfeitures recognized as they occur.

RSAs and RSUs issued by the Company generally vest ratably over three years, with the related compensation expense recognized over this period. Certain performance-based awards are subject to performance-based and market-based vesting criteria, in addition to a requisite service period. These awards cliff vest based on the specified conditions at the end of three years, with compensation expense recognized over the service period to the extent the RSUs are expected to vest. Recipients of RSAs have voting rights, while recipients of RSUs do not. Unvested RSUs and RSAs accrue dividends, which are paid out upon vesting and issuance of common shares. The fair value of time-based and performance-based RSAs and RSUs is equal to the fair market value of the Company’s common stock on the grant date. The fair value of market-based performance RSUs is estimated on the grant date using the Monte Carlo simulation model.

Earnings per Common Share-Basic earnings per common share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per common share is computed in a similar manner, except that first the denominator is increased to include the number of additional common shares that would have been outstanding if potentially dilutive common shares were issued using the treasury stock method. For all periods presented, unvested RSUs and RSAs are potentially dilutive instruments issued by the Company. Undistributed losses are not allocated to the unvested stock-based payment awards as the holders are not contractually obligated to share in the losses of the Company.

Fair Value Measurements-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. There is a three-level hierarchy for disclosure of assets and liabilities measured or disclosed at fair value. The classification of assets and liabilities within the hierarchy is based on whether the inputs to the valuation methodology used for measurement are observable or unobservable. Observable inputs reflect market-derived or market-based information obtained from independent sources, while unobservable inputs reflect estimates about market data. In general, fair values determined by Level 1 inputs utilize quoted prices for identical assets or liabilities traded in active markets that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls was determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

ASU No. 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions

The amendments in this ASU clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendments also clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. The amendments also update the disclosures for equity securities subject to contractual restrictions.

Fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023.

The Company adopted the guidance on January 1, 2024, using a prospective methodology, and it did not have a material impact on the Company's consolidated financial statements.

ASU No. 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force)

The amendments in this ASU permit companies to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the income tax credits and other income tax benefits received and recognizes the net amortization and income tax credits and other income tax benefits in the statement of income as a component of income tax expense (benefit). The amendments also require that a reporting entity disclose certain information in annual and interim reporting periods that enable investors to understand the investments that generate income tax credits and other income tax benefits from a tax credit program.

Fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023.

The Company adopted the guidance on January 1, 2024, and it did not have a material impact on the Company’s consolidated financial statements. Refer to Note 25 – Income Taxes and Investment Tax Credits for additional information.

ASU No. 2023-07, Segment Reporting (Topic 280)

The amendments improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The 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 segment disclosures in Topic 280.

Fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024.

The Company adopted the guidance for the fiscal year beginning January 1, 2024 for annual reporting. The amendments for interim periods will be adopted in our fiscal year beginning January 1, 2025. The adoption of this ASU did not have a material impact on the Company's consolidated financial statements. Refer to Note 26 – Segment Reporting for additional information.
