Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation — The accounting and reporting policies of the Company conform with the U.S. Generally Accepted Accounting Principles (“GAAP”), applicable guidelines prescribed by regulatory authorities and common practices in the banking industry. The preparation of the Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the Consolidated Financial Statements, income and expenses during the reporting period, and the related disclosures. Actual results could differ materially from those estimates. Certain items on the Consolidated Financial Statements and notes for the prior years have been reclassified to conform to the 2025 presentation.
Principles of Consolidation | Principles of Consolidation — The Consolidated Financial Statements in this Form 10-K include the accounts of East West and its subsidiaries that are majority owned and in which the Company has a controlling financial interest, and variable interest entities (“VIE”) in which the Company has determined to be the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a VIE. For a VIE, a controlling financial interest is where the Company has the power to direct the activities of an entity that most significantly impact the entity’s economic performance and has an obligation to absorb losses or the right to receive benefits from the VIE. For an entity that does not meet the definition of a VIE, the entity is determined to be a voting interest entity. The Company consolidates a voting interest entity if it can exert control over the financial and operating policies of an investee, which can occur if the Company has a more than 50% voting interest in the entity. For unconsolidated entities, the Company uses the proportional amortization method (“PAM”), equity, cost or measurement alternative method based on the Company’s voting or economic interest. East West has one wholly-owned subsidiary that is a statutory business trust (the “Trust”). In accordance with the guidance in Financial Accounting Standards Board Accounting Standards Codification (“ASC”) Topic 810, Consolidation, the Trust has not been consolidated by the Company.
Cash and Cash Equivalents | Cash and Cash Equivalents — Cash and cash equivalents include cash on hand, cash items in transit, cash due from the Federal Reserve Bank (“FRB”) of San Francisco and other financial institutions, money market funds, and federal funds sold with original maturities up to three months.
Interest-Bearing Deposits with Banks | Interest-Bearing Deposits with Banks — Interest-bearing deposits with banks include cash placed with other banks with original maturities greater than three months and less than one year.
Assets Purchased under Resale Agreements and Securities Sold under Repurchase Agreements | Assets Purchased under Resale Agreements and Securities Sold under Repurchase Agreements — Resale agreements are recorded as receivables based on the values at which the securities or loans are acquired. Repurchase agreements are accounted for as collateralized financing transactions and recorded as liabilities based on the values at which the securities are sold. The Company monitors the values of the underlying assets collateralizing the resale and repurchase agreements, including accrued interest, and obtains or posts additional collateral in order to maintain the appropriate collateral requirements for the transactions.
Debt Securities and Equity Securities | Debt Securities — Debt securities are recorded on the Consolidated Balance Sheet as of their trade dates. The Company initially classifies its debt securities as trading securities, AFS or HTM debt securities based on management’s intention on the date of the purchase. Debt securities are purchased for liquidity and investment purposes, as part of asset/liability management and other strategic activities. Debt securities for which the Company has the positive intention and ability to hold until maturity are classified as HTM and are carried at amortized cost, net of allowance for credit losses. Debt securities not classified as trading securities or HTM securities are classified as AFS. AFS debt securities are reported at fair value, net of the allowance for credit losses, with unrealized gains and losses recorded in AOCI, net of applicable income taxes. For details of the allowance for credit losses on debt securities, refer to the Allowance for Credit Losses on Available-for-Sale and Held-to-Maturity Debt Securities sections of this note. Interest income, including any amortization of premium or accretion of discount, is included in debt securities interest and dividend income in the Company’s Consolidated Statement of Income. The Company recognizes realized gains and losses on the sale of AFS debt securities in earnings, using the specific identification method. Upon transfer of a debt security from the AFS to HTM category, the security’s new amortized cost is reset to fair value, reduced by any previous write-offs but excluding any allowance for credit losses. Unrealized gains or losses at the date of transfer of these securities continue to be reported in AOCI and are amortized into interest income over the remaining life of the securities as effective yield adjustments, in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security. For transfers of securities from the AFS to HTM category, any allowance for credit losses that was previously recorded under the AFS model is reversed and an allowance for credit losses is subsequently recorded under the HTM debt security model. The reversal and re-establishment of the allowance for credit losses are recorded in the provision for credit losses. Equity Securities — The Company’s equity securities include both marketable and non-marketable equity securities. Marketable equity securities with readily determinable fair values are recorded at fair value with unrealized gains and losses due to changes in fair value, and are included in Other investment income on the Consolidated Statement of Income. Marketable equity securities include mutual fund investments, which are included in Affordable housing partnership, tax credit and CRA investments, net on the Consolidated Balance Sheet. Non-marketable equity securities including tax credit investments, and other equity investments that do not have readily determinable fair values are recorded in Affordable housing partnership, tax credit and CRA investments, net, and Other assets on the Consolidated Balance Sheet and are accounted for under one of the following accounting methods: •Equity Method — When the Company has the ability to exercise significant influence over the investee. •Proportional Amortization Method — For qualifying tax credit investments, the Company amortizes the initial cost of the investment in proportion to the income tax credits and other income tax benefits received, and recognizes the amortization in Income tax expense on the Consolidated Statement of Income. •Cost Method — The cost method is applied to restricted equity securities held for membership and regulatory purposes, such as FRB of San Francisco and FHLB stock. These investments are held at their cost minus impairment. If impaired, the carrying value is written down to the fair value of the security. •Measurement Alternative — This method is applied to all remaining non-marketable equity securities. These securities are carried at cost adjusted for impairment, if any, plus or minus observable price changes in orderly transactions of an identical or similar security of the same issuer. The Company’s impairment review for equity method, cost method and measurement alternative securities typically includes an analysis of the facts and circumstances of each security, the intent or requirement to sell the security, the expectations of cash flows, capital needs and the viability of its business model. For equity and cost method investments, the Company reduces the asset’s carrying value when the Company considers declines in value to be other-than-temporary impairment (“OTTI”). For securities accounted for under the measurement alternative, the Company reduces the asset value when the fair value is less than the carrying value, without the consideration of recovery.
Loans Held-for-Sale | Loans Held-for-Sale — Loans are initially classified as loans held-for-sale when they are individually identified as being available for immediate sale and management has committed to a formal plan to sell them. Loans held-for-sale are carried at lower of cost or fair value. Subject to periodic review under the Company’s evaluation process, including asset/liability and credit risk management, the Company may transfer certain loans from held-for-investment to held-for-sale measured at lower of cost or fair value. Any write-downs in the carrying amount of the loan at the date of transfer are recorded as charge-offs to the ALLL. Loan origination fees on loans held-for-sale, net of certain costs in processing and closing the loans, are deferred until the time of sale and are included in the periodic determination of the lower of cost or fair value adjustments and/or the gain or loss recognized at the time of sale. A valuation allowance is established if the fair value of such loans is lower than their cost. If the loan or a portion of the loan cannot be sold, it is subsequently transferred back to the loans held-for-investment portfolio from the loans held-for-sale portfolio at the lower of cost or fair value on the transfer date.
Loans Held-for-Investment | Loans Held-for-Investment — At the time of commitment to originate or purchase a loan, the loan is determined to be held-for-investment if it is the Company’s intent to hold the loan to maturity or for the foreseeable future. Loans held-for-investment are stated at their outstanding principal, reduced by an ALLL and net of deferred loan fees or costs, or unearned fees on originated loans, net of unamortized premiums or unaccreted discounts from purchased loans. Nonrefundable fees and direct costs associated with the origination or purchase of loans are deferred and netted against outstanding loan balances. The deferred net loan fees and costs are recognized in interest income as an adjustment to yield over the loan term using the effective interest method. Discounts/premiums on purchased loans are accreted/amortized to interest income using the effective interest method over the remaining contractual maturity. Interest on loans is calculated using the simple-interest method on daily balances of the principal amounts outstanding. Generally, loans are placed on nonaccrual status when they become 90 days past due or more. Loans are considered past due when contractually required principal or interest payments have not been made on the due dates. Loans are also placed on nonaccrual status when management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that full collection of principal or interest becomes uncertain, regardless of the length of past due status. Once a loan is placed on nonaccrual status, interest accrual is discontinued and all unpaid accrued interest is reversed against interest income. Interest payments received on nonaccrual loans are reflected as a reduction of principal and not as interest income. A loan is returned to accrual status when the borrower has demonstrated a satisfactory payment trend subject to management’s assessment of the borrower’s ability to repay the loan.
Loan Modifications | Loan Modifications — The Company applies the general loan modification guidance provided in ASC 310-20 to all loan modifications, including modifications made to borrowers experiencing financial difficulty. Under ASC 310-20-35-9 to 310-20-35-10, a modification is treated as a new loan only if the following two conditions are met: (1) the terms of the new loan are at least as favorable to the Company as the terms for comparable loans to other customers with similar collection risks; and (2) modifications to the terms of the original loan are more than minor. If either condition is not met, the modification is accounted for as the continuation of the existing loan with any effect of the modification treated as a prospective adjustment to the loan’s effective interest rate. A modification may vary by program and by borrower-specific characteristics, and may include rate reductions, principal forgiveness, term extensions, and payment delays, and is intended to minimize the Company’s economic loss and to avoid foreclosure or repossession of collateral. The Company applies the same credit loss methodology it uses for similar loans that were not modified. ASC 310-10-50-42 requires disclosures of modification made to borrowers experiencing financial difficulty in the forms of principal forgiveness, interest rate reductions, other-than-insignificant payment delays, term extensions or a combination of these types of modifications.
Allowance for Credit Losses | Allowance for Loan and Lease Losses — The ALLL is established as management’s estimate of expected credit losses inherent in the Company’s lending activities; it is increased by the provision for credit losses and decreased by net charge-offs. The ALLL is evaluated quarterly by management based on regular reviews of the collectability of the Company’s loans, and more often if deemed necessary. The Company develops and documents the ALLL methodology at the portfolio segment level. The commercial loan portfolio is comprised of commercial and industrial (“C&I”), commercial real estate (“CRE”), multifamily residential, and construction and land loans; and the consumer loan portfolio is comprised of single-family residential, home equity lines of credit (“HELOCs”), and other consumer loans. The ALLL represents the portion of a loan’s amortized cost basis that the Company does not expect to collect due to anticipated credit losses over the loan’s contractual life, adjusted for prepayments. The Company measures the expected loan losses on a collective pool basis when similar risk characteristics exist. Models consisting of quantitative and qualitative components are designed for each pool to develop the expected credit loss estimates. Reasonable and supportable forecast periods vary by loan portfolio. The Company has adopted lifetime loss rate models for the portfolios, which use historical loss rates and forecast economic variables to calculate the expected credit losses for each loan pool. When loans do not share similar risk characteristics, the Company evaluates the loan for expected credit losses on an individual basis. Individually assessed loans include nonaccrual loans. The Company evaluates loans for expected credit losses on an individual basis if, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the original contractual terms of the loan agreement. When the loan is deemed uncollectible, it is the Company’s policy to charge off the uncollectible amount against the ALLL. The amortized cost of loans held-for-investment excludes accrued interest, which is included in Other assets on the Consolidated Balance Sheet. The Company has made an accounting policy election to not recognize an ALLL for accrued interest receivables as the Company reverses accrued interest if a loan is on nonaccrual status. The ALLL is reported on the Consolidated Balance Sheet and the Provision for credit losses is reported on the Consolidated Statement of Income. Allowance for Unfunded Credit Commitments — The allowance for unfunded credit commitments includes reserves provided for unfunded loan commitments, letters of credit, standby letters of credit (“SBLCs”) and recourse obligations for loans sold. The Company estimates the allowance for unfunded credit commitments over the contractual period in which the entity is exposed to credit risk via a present contractual obligation to extend credit. Within the period of credit exposure, the Company considers both the likelihood that funding will occur, and the expected credit losses on the commitments that are expected to fund over their estimated lives. The allowance for unfunded credit commitments is maintained at a level believed by management to be sufficient to absorb expected credit losses related to unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities. For all off-balance sheet instruments and commitments, the unfunded credit exposure is calculated using assumptions based on the Company's historical utilization experience in related portfolio segments. Loss rates are applied to the calculated exposure balances to estimate the allowance for unfunded credit commitments. Other elements such as credit risk factors for loans outstanding, terms and expiration dates of the unfunded credit facilities, and other pertinent information are considered to determine the adequacy of the allowance. The allowance for unfunded credit commitments is included in the Accrued expenses and other liabilities on the Consolidated Balance Sheet. Changes to the allowance for unfunded credit commitments are included in Provision for credit losses on the Consolidated Income Statements. Allowance for Credit Losses on Available-for-Sale Debt Securities — For each reporting period, each AFS debt security that is in an unrealized loss position is individually analyzed as part of the Company’s ongoing assessments to determine whether a fair value below the amortized cost basis has resulted from a credit loss or other factors. The initial indicator of impairment is a decline in fair value below the amortized cost of the AFS debt security, excluding accrued interest. The Company first considers whether there is a plan to sell the AFS debt security or it is more-likely-than-not that it will be required to sell the AFS debt security before recovery of the amortized cost. In determining whether an impairment is due to credit related factors, the Company considers the severity of the decline in fair value, nature of the security, the underlying collateral, the financial condition of the issuer, changes in the AFS debt security’s ratings and other qualitative factors. For AFS debt securities that are guaranteed or issued by the U.S. government, or government-sponsored enterprises of high credit quality, the Company applies a zero credit loss assumption. When the Company does not intend to sell the impaired AFS debt security and it is more-likely-than-not that the Company will not be required to sell the impaired debt security prior to recovery of its amortized cost basis, the credit component of the unrealized loss of the impaired AFS debt security is recognized as an allowance for credit losses, with a corresponding Provision for credit losses on the Consolidated Statement of Income and the non-credit component is recognized in Other comprehensive income (loss) on the Consolidated Statement of Comprehensive Income, net of applicable taxes. At each reporting period, the Company increases or decreases the allowance for credit losses as appropriate, while limiting reversals of the allowance for credit losses to the extent of the amounts previously recorded. If the Company intends to sell the impaired debt security or it is more-likely-than-not that the Company will be required to sell the impaired debt security prior to recovering its amortized cost basis, the entire impairment amount is recognized as an adjustment to the debt security’s amortized cost basis, with a corresponding Provision for credit losses on the Consolidated Statement of Income. The amortized cost of the Company’s AFS debt securities excludes accrued interest, which is included in Other assets on the Consolidated Balance Sheet. The Company has made an accounting policy election not to recognize an allowance for credit losses for accrued interest receivables on AFS debt securities as the Company reverses any accrued interest if a debt security is impaired. As each AFS debt security has a unique security structure, where the accrual status is clearly determined when certain criteria listed in the terms are met, the Company assesses the default status of each security as defined by the debt security’s specific security structure. Allowance for Credit Losses on Held-to-Maturity Debt Securities — For each major HTM debt security type, the allowance for credit losses is estimated collectively for groups of securities with similar risk characteristics. For securities that do not share similar risk characteristics, the losses are estimated individually. The Company applies a zero credit loss assumption to certain HTM debt securities, including debt securities that are either guaranteed or issued by the U.S. government or government-sponsored enterprises, are highly rated by nationally recognized statistical rating organizations (“NRSROs”), and have a long history of no credit losses. Any expected credit loss is recorded through the allowance for credit losses and deducted from the amortized cost basis of the security, reflecting the net amount the Company expects to collect. The amortized cost of the Company’s HTM debt securities excludes accrued interest, which is included in Other assets on the Consolidated Balance Sheet. The Company has made an accounting policy election not to recognize an allowance for credit losses for accrued interest receivables on HTM debt securities, as the Company reverses any accrued interest against interest income if a debt security is placed on nonaccrual status. The criteria used to place HTM debt securities on nonaccrual are largely similar to those described for loans. Any cash collected on nonaccrual HTM debt securities is applied to reduce the security’s amortized cost basis and not as interest income. Generally, the Company returns an HTM security to accrual status when all delinquent interest and principal become current under the contractual terms of the security, and the collectability of remaining principal and interest is no longer doubtful. Allowance for Collateral-Dependent Financial Assets — A financial asset is considered collateral-dependent if repayment is expected to be provided substantially through the operation or sale of the collateral. The allowance for credit losses is measured on an individual basis for collateral-dependent financial assets and determined by comparing the fair value of the collateral less the cost to sell, to the amortized cost basis of the related financial asset at the reporting date. Other than loans, collateral-dependent financial assets could also include resale agreements. In arrangements which the borrower must continually adjust the collateral securing the asset to reflect changes in the collateral’s fair value (e.g., resale agreements), the Company estimates the expected credit losses on the basis of the unsecured portion of the amortized cost as of the balance sheet date. If the fair value of the collateral is equal to or greater than the amortized cost of the resale agreement, the expected losses would be zero. If the fair value of the collateral is less than the amortized cost of the asset, the expected losses are limited to the difference between the fair value of the collateral and the amortized cost basis of the resale agreement. Allowance for Purchased Credit Deteriorated Assets — Purchased assets that have experienced a more-than-insignificant deterioration in credit quality since origination are deemed Purchased Credit Deteriorated (“PCD”) assets. For PCD HTM debt securities and PCD loans, the company records the allowance for credit losses by grossing up the initial amortized cost, which includes the purchase price and the allowance for credit losses. The expected credit losses of PCD debt securities are measured at the individual security level. The expected credit losses for PCD loans are measured based on the loan’s unpaid principal balance. Under this approach, there is no income statement impact from the acquisition. Subsequent changes in the allowance for credit losses on PCD assets will be recognized in Provision for credit losses on the Consolidated Statement of Income. The non-credit discount or premium will be accreted to interest income based on the effective interest rate on the PCD assets determined after the gross-up for the allowance for credit losses. At the acquisition date, the initial allowance for credit losses determined on a collective basis is allocated to individual assets in accordance with ASC 326-20-30-13. Subsequent changes in the allowance for credit losses on PCD assets are recognized as Provision for credit losses (or reversal of provision for credit losses) on the Consolidated Statement of Income. Allowance for Credit Losses The Company has a current expected credit losses (“CECL”) framework for all financial assets measured at amortized cost and certain off-balance sheet credit exposures. The Company’s allowance for credit losses, which includes both the ALLL and the allowance for unfunded credit commitments, is calculated with the objective of maintaining a reserve sufficient to absorb losses inherent in our credit portfolios. The measurement of the allowance for credit losses is based on management’s best estimate of lifetime expected credit losses, periodic evaluation of the loan portfolio, lending-related commitments and other relevant factors. The allowance for credit losses is deducted from the amortized cost basis of a financial asset or a group of financial assets so that the balance sheet reflects the net amount the Company expects to collect. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts, deferred fees and costs, and escrow advances. Subsequent changes in expected credit losses are recognized in net income as a provision for, or a reversal of, credit loss expense. The allowance for credit losses estimation involves procedures to consider the unique risk characteristics of the portfolio segments. The majority of the Company’s credit exposures that share risk characteristics with other similar exposures are collectively evaluated. The collectively evaluated loans include performing loans and unfunded credit commitments. If an exposure does not share risk characteristics with other exposures, the Company generally estimates expected credit losses on an individual basis. ALLL for Collectively Evaluated Loans The allowance for collectively evaluated loans consists of a quantitative component that assesses the different risk factors considered in our models and a qualitative component that considers risk factors external to the models. Each of these components are described below. Quantitative Component — The Company applies quantitative methods to estimate ALLL by considering a variety of factors such as historical loss experience, the current credit quality of the portfolio, and an economic outlook over the life of the loan. The Company incorporates forward-looking information using macroeconomic scenarios which include variables that are considered key drivers of increases and decreases in credit losses. The Company utilizes a probability-weighted, multiple-scenario forecast approach. These scenarios may consist of a base forecast representing management's view of the most likely outcome, combined with downside or upside scenarios reflecting possible worsening or improving economic conditions. The quantitative models incorporate a probability-weighted calculation of these macroeconomic scenarios over a reasonable and supportable forecast period. If the life of the loans extends beyond the reasonable and supportable forecast period, the Company will consider historical experience or long-run macroeconomic trends over the remaining life of the loans to estimate the ALLL. There were no changes to the reasonable and supportable forecast period, and no changes to the reversion to the historical loss experience method in 2025 and 2024. The following table provides key credit risk characteristics and macroeconomic variables that the Company uses to estimate the expected credit losses by portfolio segment:
Portfolio Segment |  | Risk Characteristics |  | Macroeconomic Variables
C&I |  | Age percentage, size at origination, delinquency status, sector and risk rating |  | Unemployment rate, Gross Domestic Product (“GDP”), and U.S. Treasury rates
CRE, Multifamily residential, and Construction and land |  | Delinquency status, maturity date, collateral value, property type, and geographic location |  | Unemployment rate, GDP, and U.S. Treasury rates
Single-family residential and HELOCs |  | FICO score, delinquency status, maturity date, collateral value, and geographic location |  | Unemployment rate, GDP, and Home Price Indices
Other consumer |  | Loss rate approach |  | Immaterial - Macroeconomic variables are included in the qualitative estimate.
Quantitative Component — ALLL for the Commercial Loan Portfolio The Company’s C&I lifetime loss rate model estimates the loss rate expected over the life of a loan. This loss rate is applied to the amortized cost basis, excluding accrued interest receivable, to determine expected credit losses. The lifetime loss rate model’s reasonable and supportable period spans eight quarters, thereafter, immediately reverting to the historical average loss rate, expressed through the loan-level lifetime loss rate. To generate estimates of expected loss at the loan level for CRE, multifamily residential, and construction and land loans, projected probabilities of default (“PDs”) and loss given defaults (“LGDs”) are applied to the estimated exposure at default, considering the term and payment structure of the loan. The forecast of future economic conditions returns to long-run historical economic trends within the reasonable and supportable period. To estimate the life of a loan under both models, the contractual term of the loan is adjusted for estimated prepayments based on historical prepayment experience. Quantitative Component — ALLL for the Consumer Loan Portfolio For single-family residential and HELOC loans, projected PDs and LGDs are applied to the estimated exposure at default, considering the term and payment structure of the loan, to generate estimates of expected loss at the loan level. The forecast of future economic conditions returns to long-run historical economic trends after the reasonable and supportable period. To estimate the life of a loan for the single-family residential and HELOC loan portfolios, the contractual term of the loan is adjusted for estimated prepayments based on historical prepayment experience. For other consumer loans, the Company uses a loss rate approach. Qualitative Component — The Company considers the following qualitative factors in the determination of the collectively evaluated allowance if these factors have not already been captured by the quantitative model. Such qualitative factors may include, but are not limited to: –loan growth trends; –the volume and severity of past due financial assets, and criticized or adversely classified financial assets; –the Company’s lending policies and procedures, including changes in lending strategies, underwriting standards, collection, write-off and recovery practices; –knowledge of a borrower’s operations; –the quality of the Company’s credit review system; –the experience, ability and depth of the Company’s management and associates; –the effect of other external factors such as the regulatory and legal environments, or changes in technology; –actual and expected changes in international, national, regional, and local economic and business conditions in which the Company operates; and –risk factors in certain industry sectors not captured by the quantitative models. The magnitude of the impact of these factors on the Company’s qualitative assessment of the allowance for credit losses changes from period to period according to changes made by management in its assessment of these factors. The extent to which these factors change may depend on whether they are already reflected in quantitative loss estimates during the current period and the extent to which changes in these factors diverge from period to period. While the Company’s allowance methodologies strive to reflect all relevant credit risk factors, there continues to be uncertainty associated with, but not limited to, potential imprecision in the estimation process due to the inherent time lag of obtaining information and normal variations between expected and actual outcomes. The Company may hold additional qualitative reserves that are designed to provide coverage for losses attributable to such risk. ALLL for Individually Evaluated Loans When a loan no longer shares similar risk characteristics with other loans, such as in the case of certain nonaccrual loans, the Company estimates the ALLL on an individual loan basis. The ALLL for individually evaluated loans is measured as the difference between the recorded value of the loans and their fair value. For loans evaluated individually, the Company uses one of three different asset valuation measurement methods: (1) the fair value of collateral less costs to sell; (2) the present value of expected future cash flows; or (3) the loan's observable market price. If an individually evaluated loan is determined to be collateral dependent, the Company applies the fair value of the collateral less costs to sell method. If an individually evaluated loan is determined not to be collateral dependent, the Company uses the present value of future cash flows or the observable market value of the loan. •Collateral-Dependent Loans — The allowance of a collateral-dependent loan is limited to the difference between the recorded value and fair value of the collateral less cost of disposal or sale.
Premises and Equipment, Net | Premises and Equipment, Net — The Company’s premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed based on the straight-line method over the estimated useful lives of the various classes of assets. The ranges of estimated useful lives for the principal classes of assets are as follows:
Premises and Equipment |  | Useful Lives
Buildings |  | 25 years
Building improvements |  | 15 years
Furniture, fixtures and equipment, including computer equipment |  | 3 to 7 years
Leasehold improvements |  | Remaining term of lease or useful life, whichever is shorter
The Company reviews its long-lived assets for impairment annually, or when events or changes in circumstances indicate that the carrying amounts of these assets may not be recoverable. An asset is considered impaired when the fair value, which is the expected undiscounted cash flows over the remaining useful life, is less than the net book value. The excess of the net book value over its fair value is charged as impairment loss to noninterest expense.
Goodwill | Goodwill — Goodwill represents the excess of the purchase price over the fair value of net assets acquired in an acquisition. Goodwill is tested for impairment on an annual basis as of December 31, or more frequently if an event occurs or circumstances change that indicate a potential impairment at the reporting unit level. The Company assesses goodwill for impairment at each operating segment level. The Company organizes its operations into three reporting segments: (1) Consumer and Business Banking; (2) Commercial Banking; and (3) Treasury and Other. For information on how the reporting units are identified and the components are aggregated, see Note 17 — Business Segments to the Consolidated Financial Statements in this Form 10-K. The Company has the option to perform a qualitative assessment of goodwill or elect to bypass the qualitative test and proceed directly to a quantitative test. If the Company performs a qualitative assessment of goodwill to test for impairment and concludes it is more likely than not that a reporting unit’s fair value is greater than its carrying value, quantitative tests are not required. If the qualitative analysis indicates that it is more likely than not that a reporting unit’s fair value is less than its carrying value, the Company is required to perform a quantitative assessment to determine if there is goodwill impairment. Factors considered in the qualitative assessments include but are not limited to macroeconomic conditions, industry and market considerations, financial performance of the respective operating segment and other relevant entity- and reporting-unit specific considerations. A quantitative valuation involves determining the fair value of each reporting unit and comparing the fair value to its corresponding carrying value. Goodwill impairment loss is recorded as a charge to noninterest expense and an adjustment to the carrying value of goodwill. Subsequent reversals of goodwill impairment are not allowed. The Company’s goodwill impairment test is performed annually, as of December 31, or more frequently if events occur or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying value.
Derivatives | Derivatives — As part of its asset/liability management strategy, the Company uses derivative financial instruments to mitigate exposure to interest rate and foreign currency risks, and to assist customers with their risk management objectives. Derivatives utilized by the Company primarily include swaps, forwards and option contracts. Derivative instruments are included in Other assets or Accrued expenses and other liabilities on the Consolidated Balance Sheet at fair value. All derivatives designated as fair value hedges and hedges of the net investments in certain foreign operations are linked to specific hedged items or to groups of specific assets and liabilities on the Consolidated Balance Sheet. Cash flow hedges are linked to the forecasted transactions related to a recognized asset/liability or to groups of recognized assets/liabilities. The related cash flows impacts of derivatives are recognized on the Cash flows from operating activities section on the Consolidated Statement of Cash Flows. The Company uses accounting hedges based on the exposure being hedged as either fair value hedges, cash flow hedges or hedges of the net investments in certain foreign operations. For fair value hedges of interest rate risk, changes in fair value of derivatives are reported in the same line item where the earnings effect of the hedged item is presented, as Interest expense or Interest and dividend income on the Consolidated Statement of Income. Changes in fair value of derivatives designated as hedges of the net investments in foreign operations are recorded as a component of AOCI. For cash flow hedges of floating-rate interest payments or receipts, the change in the fair value of hedges is recognized in AOCI on the Consolidated Balance Sheet and reclassified to earnings in the same period when the hedged cash flows impact earnings. The changes in the fair value of the hedging instrument are recorded in the same income statement line item as the hedged item’s expense or income is recorded. For example, fair value changes of hedges on borrowings are recorded within Interest expense, and fair value changes of hedges on loan assets are recorded as interest income within Interest and dividend income on the Consolidated Statements of Income. To qualify as an accounting hedge under the hedge accounting rules (versus an economic hedge where hedge accounting is not sought), a derivative must be highly effective in offsetting the risk designated as being hedged at the inception and on an ongoing basis. The Company evaluates the hedge effectiveness and formally documents its hedging relationships at inception, including the identification of the hedging instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction at the time the derivative contract is executed. Subsequent to inception, on a quarterly basis, the Company assesses whether the derivatives used in hedging transactions are highly effective in offsetting changes in the fair value of the hedged items or the cash flows of attributable hedged risks. The quarterly assessment is performed on both a prospective basis (to reconfirm forward-looking expectations that the hedge will be highly effective) and a retrospective basis (to determine whether the hedging relationship was highly effective). The Company discontinues hedge accounting prospectively when (i) a derivative is no longer highly effective in offsetting the risk being hedged; (ii) a derivative expires, or is sold, terminated or exercised, or (iii) the Company determines that designation of a derivative as a hedge is no longer appropriate. If a fair value hedge is discontinued, the derivative will continue to be recorded on the Consolidated Balance Sheet at fair value with changes in fair value recognized on the Consolidated Statement of Income. When the hedged net investment is discontinued, any amounts that have not yet been recognized in earnings remain in AOCI until the net investment is either sold or substantially liquidated where the changes in the fair value of the derivatives are reclassified out of AOCI into Foreign exchange income on the Consolidated Statement of Income. If a cash flow hedge is discontinued but the hedged forecasted cash flow is still expected to happen, the derivative net gain or loss will remain in AOCI and be reclassified into earnings in the periods in which the hedged forecasted cash flow affects earnings. If a cash flow hedge is discontinued and it becomes probable that the forecasted cash flow is not expected to happen, the derivative net gain or loss will be reclassified into earnings immediately. The Company also offers various interest rate, commodity and foreign exchange derivative products to customers. These derivative contracts are recorded at fair value with changes in fair value recorded in Customer derivative income or Foreign exchange income on the Consolidated Statement of Income. As part of its loan origination process, the Company may periodically receive equity warrants to purchase preferred and/or common stock of the public or private companies to which it provides loans. Separately, the Company granted performance-based restricted stock units (“RSUs”) as part of its consideration for an investment made during the third quarter of 2023. The vesting of these performance-based RSUs is contingent on the investee meeting certain financial performance targets during the future performance period. These equity contracts are accounted for as derivatives and recorded at fair value in Other assets or Accrued expenses and other liabilities on the Consolidated Balance Sheet with changes in fair value recorded in Lending fees, for equity warrants related to the loan origination process, or Other investment income, for performance-based RSU’s, on the Consolidated Statement of Income. The Company is exposed to counterparty credit risk, which is the risk that counterparties to the derivative contracts do not perform as expected. Valuation of derivative assets and liabilities reflect the value of the instrument inclusive of the nonperformance risk. The Company uses master netting arrangements to mitigate counterparty credit risk in derivative transactions. To the extent the derivatives are subject to master netting arrangements, the Company takes into account the impact of master netting arrangements that allow the Company to set off all derivative contracts executed with the same counterparty on a net basis, and to offset the net derivative position with the related cash and securities collateral. The Company elects to offset derivative transactions with the same counterparty on the Consolidated Balance Sheet when a derivative transaction has a legally enforceable master netting arrangement and when it is eligible for netting under ASC 210-20-45-1, Balance Sheet Offsetting: Netting Derivative Positions on Balance Sheet. Derivative balances and related cash collateral are presented net on the Consolidated Balance Sheet. In addition, the Company applies the Settlement to Market treatment for the cash variation margin received/pledged on our interest rate and commodity contracts cleared through certain centrally cleared counterparties. As a result, derivative balances with these counterparties are considered settled by the variation margin.
Fair Value | Fair Value — The Company records or discloses certain assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or the price that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining the fair value of financial instruments, the Company uses various methods including market and income approaches. Based on these approaches, the Company utilizes certain assumptions that market participants would use in pricing an asset or a liability. These inputs can be readily observable, market corroborated or generally unobservable. Fair value measurements are based on the exit price notion that maximizes the use of observable inputs and minimizes the use of unobservable inputs. However, for certain instruments, the Company must utilize unobservable inputs in determining fair value due to the lack of observable inputs in the market, which requires greater judgment in the measurement of fair value. All inputs, whether observable or unobservable, are ranked in accordance with a prescribed fair value hierarchy that assigns the highest priority to quoted prices in active markets and the lowest priority to prices derived from data lacking transparency. The Company’s assets and liabilities are classified in their entirety based on the lowest level of input that is significant to their fair value measurements. The fair value of the Company’s assets and liabilities is classified and disclosed in one of the following three categories: •Level 1 — Valuation is based on quoted prices for identical instruments traded in active markets. •Level 2 — Valuation is based on quoted prices for similar instruments traded in active markets; quoted prices for identical or similar instruments traded in markets that are not active; and model-derived valuations whose inputs are observable and can be corroborated by market data. •Level 3 — Valuation is based on significant unobservable inputs for determining the fair value of assets or liabilities. These significant unobservable inputs reflect assumptions that market participants may use in pricing the assets or liabilities.
Stock-Based Compensation | Stock-Based Compensation — The Company grants time-based RSUs, which include service conditions for vesting. RSUs that vest in the form of shares of the Company’s common stock are classified as equity. Compensation cost for these time-based awards is based on the quoted market price of the Company’s common stock at the grant date. RSUs that will be settled in cash instead of shares are liability classified awards and compensation cost for these awards is adjusted to fair value based on changes in the Company’s stock price up to the settlement date. In addition, the Company grants performance-based RSUs, which contain additional performance goals and market conditions that are required to be met in order for the awards to vest. Compensation expense for these performance-based RSUs is based on the grant-date fair value considering both performance and market conditions. Subsequently, the Company evaluates the probable outcome of the performance conditions quarterly and makes cumulative adjustments for current and prior periods in compensation expense in the period of change. Market conditions subsequent to the grant date have no impact on the amount of compensation expense. Compensation cost is amortized on a straight-line basis over the requisite service period for the entire award, reduced by expected forfeitures. Effective third quarter 2025, compensation cost related to awards granted to employees who meet certain age plus years-of-service requirements (“retirement-eligible employees”) is accrued over the service period required to earn the award prior to the grant date, in accordance with ASC 718-10-55-108. This change in the timing of recognition for awards that were granted to or are expected to be granted to retirement-eligible employees resulted in $31 million of additional compensation expense in 2025. Forfeitures are estimated at the time of grant and are updated quarterly. If the estimated forfeitures are revised, a cumulative effect of changes in estimated forfeitures for the current and prior periods is recognized in compensation expense in the period of change. Excess tax benefits and deficiencies on share-based payment awards are recognized within Income tax expense on the Consolidated Statement of Income.
Revenue from Contracts with Customers | Revenue from Contracts with Customers — The Company recognizes two primary types of revenue on its Consolidated Statement of Income: Net interest income and Noninterest income. The Company’s revenue from contracts with customers consists of service charges and fees related to deposit accounts, card income and wealth management fees. These revenue streams as described below comprised 43%, 43% and 41% of total noninterest income for the years ended December 31, 2025, 2024 and 2023, respectively. •Deposit Service Charges and Related Fee Income — The Company offers a range of deposit products to individuals and businesses, which includes savings, money market, checking and time deposit accounts. In addition to ongoing maintenance charges, treasury management and business account analysis services are offered to commercial deposit customers. Other optional services such as various in-branch services, automated teller machine/debit card usage, wire transfer services or check orders are also offered. The monthly account fees may vary with the amount of average monthly deposit balances maintained, or the Company may charge a fixed monthly account maintenance fee if certain average balances are not maintained. In addition, each time a deposit customer selects an optional service, the Company may earn transaction fees, generally recognized by the Company at the point when the transaction occurs. For business analysis accounts, commercial deposit customers receive an earnings credit based on their account balance, which can be used to offset the cost of banking and treasury management services. Business analysis accounts that are assessed fees in excess of earnings credits received are typically charged at the end of each month, after all transactions are known and the credits are calculated. Deposit service charges and related fee income are recognized in all operating segments and included in Commercial and consumer d eposit-related account fees on the Consolidated Statement of Income. •Wealth Management Fees — The Company provides investment planning services for customers including wealth management services, asset allocation strategies, portfolio analysis and monitoring, investment strategies and risk management strategies. The fees the Company earns are variable and are generally received monthly. The Company recognizes revenue for the services performed at quarter-end based on actual transaction details received from the broker-dealer with whom the Company engages. Wealth management fees are recognized in both consumer and business banking, and commercial banking segments. •Card Income — Card income primarily consists of merchant referral fees where the Company provides marketing and referral services to acquiring banks for merchant card processing services and earns variable referral fees based on transaction activities. The Company satisfies its performance obligation over time as the Company identifies, solicits, and refers business customers who are provided such services. Card income is recognized in the consumer and business banking, and commercial banking segments and is included in Commercial and consumer deposit-related fees on the Consolidated Statement of Income.
Income Taxes | Income Taxes — The Company files consolidated federal income tax returns, foreign tax returns, and various combined and separate company state tax returns. The calculation of the Company’s income tax provision and related tax accruals requires the use of estimates and judgments. Income tax expense consists of two components: current and deferred. Current tax expense represents taxes to be paid or refunded for the current period and includes income tax expense related to our uncertain tax positions. Income tax liabilities (receivables) represent the estimated amounts due to (due from) the various taxing jurisdictions where the Company has established a tax presence and are reported in Accrued expenses and other liabilities or Other assets on the Consolidated Balance Sheets. Deferred tax expense results from changes in deferred tax assets and liabilities between periods, and is determined using the balance sheet method. Under the balance sheet method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities. Deferred tax assets are also recognized for tax attributes such as net operating loss carryforwards and tax credit carryforwards. Management regularly reviews the Company’s tax positions and deferred tax balances. In concluding whether a valuation allowance is required, the Company considers all available evidence, both positive and negative, based on the more-likely-than-not criteria that such assets will be realized. Factors considered in this analysis include the Company’s ability to generate future taxable income, implement tax-planning strategies (as defined in ASC 740, Income Taxes) and utilize taxable income from prior carryback years (if such carryback is permitted under the applicable tax law), as well as future reversals of existing taxable temporary differences. To the extent a deferred tax asset is no longer expected more-likely-than-not to be realized, a valuation allowance is established. Deferred tax assets net of deferred tax liabilities are included in Other assets on the Consolidated Balance Sheet. The Company reports a liability for unrecognized tax benefits resulting from uncertain tax positions taken, or expected to be taken, in an income tax return. 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 largest amount of benefit that management believes has a greater than 50% likelihood of realization upon settlement. Tax benefits not meeting our realization criteria represent unrecognized tax benefits. The Company establishes a liability for potential taxes, interest and penalties related to uncertain tax positions based on facts and circumstances, including the interpretation of existing law, new judicial or regulatory guidance, and the status of tax audits. The Company uses the PAM for affordable housing partnership investments, whereby the associated tax credits are recognized as a reduction to tax expense. Upon the adoption of ASU 2023-02 on January 1, 2024, the Company also began applying the PAM to new markets, historic, production and renewable energy tax credit investments. The Company also holds investments in other tax credit investments using either equity method or the measurement alternative method of accounting. These tax credits are recognized on the Consolidated Financial Statements to the extent they are utilized on the Company’s income tax returns in the year the credit arises under the flow through method of accounting. From time to time, the Company purchases tax credits. The purchased credit is either recorded as an adjustment to income taxes refundable (payable) or as a deferred tax asset, or if the purchased credit is expected to be carried forward to be utilized on future income tax returns, the difference between the purchase price, including direct costs to acquire the credit, and the purchased tax credit is recognized as a deferred credit. The deferred credit is recognized in income tax expense in proportion to the reversal of the associated deferred tax asset.
Earnings Per Share | Earnings Per Share — Basic EPS is computed by dividing net income by the weighted-average number of outstanding common shares. Outstanding common shares include contingently issuable shares when the contingent condition has been satisfied. Employee share-based payment awards in the form of shares that vest when an employee retires or become retirement-eligible are treated as contingently issuable shares. Diluted EPS is computed by taking net income, adjusted for fair value changes of liability-classified equity contracts that are share-settled, divided by the weighted-average number of common shares outstanding during each period, plus any incremental dilutive common share equivalents calculated for outstanding time- and performance-based RSUs and contingently issuable shares computed using the treasury stock method.
Foreign Currency Translation | Foreign Currency Translation — When the functional currency of a foreign operation differs from the Company’s reporting currency, the U.S. dollar (“USD”), the assets and liabilities of the foreign operations are translated, for consolidation purposes, from the functional currency to the Company’s reporting currency using period-end spot foreign exchange rates. Revenues and expenses of the foreign operations are translated, for the purpose of consolidation, from its functional currency into the reporting currency USD at the transaction date foreign exchange rates. The effects of these translation adjustments are reported in the Foreign currency translation adjustments account within Other comprehensive income (loss) on the Consolidated Statement of Comprehensive Income, net of any related hedged effects. For transactions that are denominated in a currency other than the functional currency, including transactions denominated in the local currencies of foreign operations that use the USD as their functional currency, the effects of changes in exchange rates are reported in Foreign exchange income on the Consolidated Statement of Income.

ASU No. 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements | January 1, 2027 Early adoption is permitted. | ASU 2025-09 addresses five specific matters: 1.Broadens the set of hedged risk that may be combined within a group of individual forecasted transactions in a cash flow hedge. 2.Enables entities to apply cash flow hedge accounting on “choose-your-rate” debt. 3.Broadens situations where hedge accounting can be applied to forecasted purchases and sales of nonfinancial assets. 4.Removes the requirement to perform net written option assessment for a compound derivative when it is designated as a hedging instrument. 5.In the case of a dual hedge where a foreign- currency-denominated debt instrument is designated as the hedging instrument in a net investment hedge and a hedged item in a fair value of interest rate risk, the ASU requires the debt instruments’ fair value-hedge basis adjustment be excluded when performing the net investment hedge effectiveness assessment. This guidance must be applied prospectively for all hedging relationships. The Company may elect to adopt this ASU amendments for hedging relationships as of the adoption date. | The Company is currently evaluating the impact of this guidance and does not expect adoption to have a material impact on the Company’s Consolidated Financial Statements.

Standard | Required Date of Adoption | Description | Effect on Financial Statements
ASU No. 2025-08, Financial Instruments—Credit Losses (Topic 326) | January 1, 2027 Early adoption is permitted. | ASU 2025-08 broadens the population of financial assets that are within scope of the gross up approach under ASC 326 to include purchased seasoned loans which are defined as: •Non-PCD loans that are obtained in a business combination. •Non-PCD loans that are (1) obtained in an asset acquisition or upon consolidation of a VIE that is not a business and (2) are acquired more than 90 days after their origination date by a transferee that was not involved in their origination. The guidance introduces an accounting policy election to use the amortized cost basis of the asset rather than the discounted cash flow analysis to subsequently measure the credit losses on purchased seasoned loans. The new guidance is not applicable to credit card loans, ASC 606 receivables, or debt securities. The guidance must be applied prospectively. | The Company is currently evaluating the impact of this guidance on the Company’s Consolidated Financial Statements.

Balance Sheet Offsetting | The Company’s resale and repurchase agreements are transacted under legally enforceable master netting agreements that, in the event of default by the counterparty, provide the Company the right to liquidate securities held and to offset receivables and payables with the same counterparty. The Company nets resale and repurchase transactions with the same counterparty on the Consolidated Balance Sheet when it has a legally enforceable master netting agreement and the transactions are eligible for netting under ASC 210-20-45-11, Balance Sheet Offsetting: Repurchase and Reverse Repurchase Agreements. Collateral received includes securities and loans that are not recognized on the Consolidated Balance Sheet. Collateral pledged consists of securities that are not netted on the Consolidated Balance Sheet against the related collateralized liability.
Credit Quality Indicators | Credit Quality Indicators All loans are subject to the Company’s credit review and monitoring process. For the commercial loan portfolio, loans are risk rated based on an analysis of the borrower’s current payment performance or delinquency, repayment sources, financial and liquidity factors, including industry and geographic considerations. For the consumer loan portfolio, payment performance or delinquency is typically the driving indicator for risk ratings. The Company utilizes internal credit risk ratings to assign each individual loan a risk rating of 1 through 10: •Pass — loans risk rated 1 through 5 are assigned an internal risk rating category of “Pass.” Loans risk rated 1 are typically loans fully secured by cash. Pass loans have sufficient sources of repayment to repay the loan in full, in accordance with all terms and conditions. •Special mention — loans assigned a risk rating of 6 have potential weaknesses that warrant closer attention by management; these are assigned an internal risk rating category of “Special Mention.” •Substandard — loans assigned a risk rating of 7 or 8 have well-defined weaknesses that may jeopardize the full and timely repayment of the loan; these are assigned an internal risk rating category of “Substandard.” •Doubtful — loans assigned a risk rating of 9 have insufficient sources of repayment and a high probability of loss; these are assigned an internal risk rating category of “Doubtful.” •Loss — loans assigned a risk rating of 10 are uncollectible and of such little value that they are no longer considered bankable assets; these are assigned an internal risk rating category of “Loss.” Loan exposures categorized as criticized consist of special mention, substandard, doubtful and loss categories. The Company reviews the internal risk ratings of its loan portfolio on a regular basis, and adjusts the ratings based on changes in the borrowers’ financial status and the collectability of the loans.
Litigation | Litigation — The Company is a party to various legal actions arising in the ordinary course of its business. In accordance with ASC 450, Contingencies, the Company accrues reserves for outstanding lawsuits, claims and proceedings when a loss contingency is probable and can be reasonably estimated. The Company estimates the amount of loss contingencies using current available information from legal proceedings, advice from legal counsel and available insurance coverage. Due to the inherent subjectivity of the assessments and unpredictability of the outcomes of the legal proceedings, any amounts accrued or included in this aggregate amount may not represent the ultimate loss to the Company from the legal proceedings in question.
