Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies 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 subsidiaries including its wholly owned banking subsidiary Umpqua Bank (the "Bank") and Columbia Trust Company ("Columbia Trust"). 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 has been accounted for as a business combination. Columbia's financial results for any periods ended prior to February 28, 2023 reflect UHC results only on a standalone basis. In addition, Columbia's reported financial results for the three months ended March 31, 2023 reflect UHC financial results only until the closing of the Merger after the close of business on February 28, 2023. 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 as of February 28, 2023 ("historical Columbia") were recorded at their respective fair values. Refer to Note 2 - Business Combination for additional information on this acquisition. Columbia Banking System, Inc. is headquartered in Tacoma, Washington, and is engaged primarily in the business of commercial and retail banking. Columbia Trust provides fiduciary, agency, trust and related services, and life insurance products. 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 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 allowance for credit losses, business combinations, and goodwill. In connection with the Merger, effective February 28, 2023, the Company realigned its operating segments based on changes in its internal reporting structure and changes to the Company's Chief Operating Decision Maker. The Company now reports as a single reportable segment. Previously UHC reported two segments: Core Banking and Mortgage Banking, however in 2022 the mortgage banking segment's scale of mortgage operations was downsized as a smaller impact on the financial statements was expected in the future. The revised presentation of segment data has been applied retroactively for all periods presented in these financial statements. 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. As of June 30, 2023, the Company had 23 wholly-owned trusts that were formed to issue trust preferred securities and related common securities. 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 sheet 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 allowance for credit losses, 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 allowance for credit losses. 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 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. Originated 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. 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. Acquired Loans and Leases-Loans and leases purchased 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 allowance for credit loss 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. Income Recognition on Non-Accrual Loans-Loans are classified as non-accrual if the collection of principal and interest is doubtful. Generally, this occurs when a commercial or commercial real estate 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. Allowance for Credit Losses-ASC Topic 326 requires an expected loss model, which encompasses allowances for credit losses expected to be incurred over the life of the portfolio. The CECL model requires the measurement of all expected credit losses for financial assets measured at amortized cost and certain off-balance-sheet credit exposures based on historical experience, current conditions, and reasonable and supportable forecasts. The allowance for credit losses on loans and leases is the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments. 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. Fluctuations in the allowance are reported in the statement of operations as a component of provision for credit losses. 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. CECL is not prescriptive in the methodology used to determine the expected credit loss estimate. Instead, management has flexibility in selecting the methodology. The expected credit losses must be estimated over a financial asset's contractual term, adjusted for prepayments utilizing quantitative and qualitative factors. There are also specific considerations for Purchased Credit-Deteriorated and Collateral Dependent Loans. 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. 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. The Company utilizes complex models to obtain reasonable and supportable forecasts. Most of the models calculate two predictive metrics: the probability of default and loss given default. 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. Management believes that the ACL was adequate as of June 30, 2023. 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 Loans-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 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 reserve for unfunded commitments is maintained at a level that, in the opinion of management, is adequate to absorb inherent 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 allowance for credit loss on loans and leases 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 reserve for unfunded commitments, which is included in the Other Liabilities section of the consolidated balance sheets. Loan and Lease Fees and Direct Loan Origination Costs-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 estimated life of the loan. 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 provided over the estimated useful life of equipment, generally three to ten years, on a straight-line or accelerated basis. Depreciation is provided over the estimated useful life of 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. 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. Intangible assets with definite useful lives are amortized to their estimated residual values over their respective estimated useful lives, and also reviewed for impairment. Amortization of intangible assets is included in non-interest expense. On at least an annual basis, goodwill is assessed for impairment at the reporting unit level either qualitatively or quantitatively. Additionally, goodwill is evaluated on an interim basis when events or circumstances indicate impairment potentially exists. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. 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. A significant increase in the discount rate would reduce the value of the MSR. GNMA Loan Sales-The Company originates government guaranteed loans, which are sold to Government National Mortgage Association. Pursuant to GNMA servicing guidelines, the Company has the unilateral right to repurchase certain delinquent loans (loans past due 90 days or more) sold to GNMA, if the loans meet defined delinquent loan criteria. As a result of this unilateral right, once the delinquency criteria has been met, and regardless of whether the repurchase option has been exercised, the Company accounts for the loans as if they had been repurchased. The Company recognizes these loans within loans and leases, net and also recognizes a corresponding liability that is recorded in other liabilities. If the loan is repurchased, the liability is settled and the loan remains. SBA/USDA Loans Sales, Servicing, and Commercial Servicing Asset-The Bank, on a limited basis, sells or transfers loans, including the guaranteed portion of SBA and USDA loans (with servicing retained) for cash proceeds. The Bank records a servicing asset when it sells a loan and retains the servicing rights. The servicing asset is recorded at fair value upon sale, and the fair value is estimated by discounting estimated net future cash flows from servicing using discount rates that approximate current market rates and using estimated prepayment rates. Subsequent to initial recognition, the servicing rights are carried at the lower of amortized cost or fair value and are amortized in proportion to, and over the period of, the estimated net servicing income. 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, and financial services 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 consists 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. •Finance 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, merchant fee income, 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 operations for the grant-date fair value of RSUs and RSAs issued to employees over the employees' requisite service period (generally the vesting period). An estimate of expected forfeitures is included in the calculation of stock-based compensation expense over the vesting period, and actual forfeitures are recognized when they occur. The fair value of the RSUs and RSAs is based on the Company's share price on the grant date. Unvested RSUs and RSAs participate with common stock in any dividends declared but are only paid on the shares that ultimately vest. RSUs and RSAs generally vest ratably over three years and are recognized as compensation expense over that same period of time. Certain RSU's (performance share units) are subject to performance-based and market-based vesting criteria in addition to a requisite service period and cliff vest based on those conditions at the end of three years. At the time of vesting, the vested shares are entitled to receive cumulative dividends declared and paid during the three years. Compensation expense is recognized over the service period to the extent RSUs and RSAs are expected to vest. The fair value of the performance-based RSU grants is estimated as of the grant date using a Monte Carlo simulation pricing model. Earnings (Loss) per Common Share-Basic earnings (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) 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 has been 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. Application of new accounting guidance In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in this ASU improve comparability for both the recognition and measurement of acquired revenue contracts with customers at the date of and after a business combination. The ASU specifies for all acquired revenue contracts regardless of their timing of payment (1) the circumstances in which the acquirer should recognize contract assets and contract liabilities that are acquired in a business combination and (2) how to measure those contract assets and contract liabilities. The amendments improve comparability after the business combination by providing consistent recognition and measurement guidance for revenue contracts with customers acquired in a business combination and revenue contracts with customers not acquired in a business combination. The Company adopted the guidance on January 1, 2023 and it did not have a material impact on the Company's consolidated financial statements. In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The ASU addresses areas identified by the FASB as part of its post-implementation review of the credit losses standard (ASU 2016-13) that introduced the CECL model. The amendments eliminate the accounting guidance for troubled debt restructurings by creditors that have adopted CECL and enhance the disclosure requirements for loan refinancings and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require a public business entity to disclose current-period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. The Company adopted the guidance on January 1, 2023, using a prospective methodology, noting that the updates pertain to disclosures but did not have a material impact on the Company's consolidated financial statements. Refer to Note 5 - Allowance for Credit Losses for additional information. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU was issued to provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference London Inter-Bank Offered Rate or another reference rate expected to be discontinued. The last expedient is a one-time election to sell or transfer debt securities classified as held to maturity. In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope. The amendments in this Update are elective and apply to all entities that have derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. The amendments clarify certain optional expedients and exceptions in Topic 848 for contract modifications apply to derivatives that are affected by the discounting transition. In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. The amendment deferred the sunset date of Topic 848 from December 31, 2022 to December 31, 2024. The Company fully adopted ASU 2020-04 and ASU 2021-01 in July of 2023 and it did not have a material impact on the Company's consolidated statements. Many of the Bank's loans transitioned from LIBOR to SOFR prior to June 30, 2023, which is the Bank's preferred replacement index for most LIBOR loans. The remaining LIBOR loans transitioned to SOFR, or an alternative replacement index, at the beginning of July 2023. Recent accounting pronouncements In June 2022, the FASB issued 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. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, with early adoption permitted. The amendment will be applied prospectively. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. In March 2023, the FASB issued 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 operations 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. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, with early adoption permitted. The amendments in the ASU can be applied either on a modified retrospective or a retrospective basis. The Company is currently evaluating the impact of this ASU on the Company's consolidated financial statements.
