Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Consolidation | East West Bancorp, Inc. (referred to herein on an unconsolidated basis as “East West” and on a consolidated basis as the “Company”) is a registered bank holding company that offers a full range of banking services to individuals and businesses through its subsidiary bank, East West Bank and its subsidiaries (“East West Bank” or the “Bank”). The unaudited interim Consolidated Financial Statements in this Form 10-Q include the accounts of East West, East West Bank and East West’s subsidiaries. Intercompany transactions and accounts have been eliminated in consolidation. As of September 30, 2020, East West also has six wholly-owned subsidiaries that are statutory business trusts (the “Trusts”). In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, Consolidation, the Trusts are not included on the Consolidated Financial Statements.
Basis of Presentation | The unaudited interim Consolidated Financial Statements are presented in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”), applicable guidelines prescribed by regulatory authorities, and general practices in the banking industry. They reflect all adjustments that, in the opinion of management, are necessary for fair statement of the interim Consolidated Financial Statements. Certain items on the Consolidated Financial Statements and notes for the prior periods have been reclassified to conform to the current period presentation.

Standards Adopted in 2020
ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and subsequent related ASUs | January 1, 2020 Early adoption is permitted on January 1, 2019. | The ASU introduces a new current expected credit losses (“CECL”) model that applies to most financial assets measured at amortized cost and certain instruments, including trade and other receivables, loan receivables, AFS and held-to-maturity debt securities, net investments in leases and off-balance sheet credit exposures. The CECL model utilizes a lifetime “expected credit loss” measurement objective for the recognition of credit losses at the time the financial asset is originated or acquired. The expected credit losses are adjusted in each period for changes in expected lifetime credit losses. ASU 2016-13 also eliminates the guidance for purchased credit impaired (“PCI”) loans, but requires an allowance for loan losses for purchased financial assets with more than an insignificant deterioration of credit since origination. The ASU also modifies the other-than-temporary impairment (“OTTI”) model for AFS debt securities to require an allowance for credit losses instead of a direct write-down. A reversal of the allowance for credit losses is allowed in future periods based on improvements in credit performance expectations. This ASU expands the disclosure requirements regarding an entity’s assumptions, models and methods for estimating the allowance for loan and lease losses, and requires disclosure of the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination (i.e., by vintage year). The guidance should be applied using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the reporting period of adoption. The new guidance also allows optional relief for certain instruments measured at amortized cost with an option to irrevocably elect the fair value option under ASC Topic 825, Financial Instruments. | The Company adopted ASU 2016-13 using a modified retrospective approach on January 1, 2020 without electing the fair value option on eligible financial instruments under ASU 2019-05. The adoption of this ASU increased the allowance for loan losses by $125.2 million, and allowance for unfunded credit commitments by $10.5 million and an after-tax decrease to opening retained earnings of $98.0 million on January 1, 2020. The increase to allowance for loan losses was primarily related to the commercial and industrial (“C&I”) and commercial real estate (“CRE”) loan portfolios. The Company did not record an allowance for credit losses related to the Company’s AFS debt securities as a result of this adoption. Disclosures for periods after January 1, 2020 are presented in accordance with ASC 326 while prior period amounts continue to be reported in accordance with previously applicable standards and the accounting policies described in the Company’s 2019 Form 10-K. The Company has elected the CECL phase-in option provided by regulatory capital rules, which delays the impact of CECL on regulatory capital for two years, followed by a three-year transition period.
ASU 2017-04, Intangibles — Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment | January 1, 2020 Early adoption is permitted for interim or annual goodwill impairment tests with measurement dates after January 1, 2017. | The ASU simplifies the accounting for goodwill impairment. Under this guidance, an entity will no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, an impairment loss will be recognized when the carrying amount of a reporting unit exceeds its fair value and the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The guidance also eliminates the requirement to perform a qualitative assessment for any reporting units with a zero or negative carrying amount. This guidance should be applied prospectively. | The Company adopted this guidance on January 1, 2020. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.
ASU 2018-15, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract | January 1, 2020 | The ASU amends ASC Topic 350-40 to align the accounting for costs incurred in a cloud computing arrangement with the guidance on developing internal use software. Specifically, if a cloud computing arrangement is deemed to be a service contract, certain implementation costs are eligible for capitalization. The new guidance prescribes the balance sheet and income statement presentation and cash flow classification for the capitalized costs and related amortization expense. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. | The Company adopted this guidance on a prospective basis on January 1, 2020. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting | Effective for all entities as of March 12, 2020 through December 31, 2022. | In March 2020, the FASB issued a new accounting standard related to contracts or hedging relationships that reference London interbank offered rate or other reference rates that are expected to be discontinued due to reference rate reform. This ASU provides temporary optional expedients and exceptions regarding the accounting requirements related to the modification of certain contracts, hedging relationships and other transactions that are affected by the reference rate reform. The guidance permits the Company to make a one-time election to sell and/or transfer qualifying held-to-maturity securities, and not to apply modification accounting or remeasure lease payments in lease contracts if the changes to the contract are related to the discontinuation of the reference rate. If certain criteria are met, the amendments also allow exceptions to the de-designation criteria of the hedging relationship and the assessment of hedge effectiveness during the transition period. This one time election may be made at any time after March 12, 2020, but no later than December 31, 2022. | The Company has not yet made a determination on whether it will make this election and is currently tracking the exposure as of each reporting period and assessing the significance of impact towards implementing any necessary modification in consideration of the election of this amendment. The Company will continue to assess the impact as the reference rate transition occurs over the next two years.
Summary of Significant Accounting Policies The Company has revised the following significant accounting policies. Allowance for Loan Losses — The allowance for loan losses is established as management’s estimate of expected credit losses inherent in the Company’s lending activities and increased by the provision for credit losses and decreased by net charge-offs. The allowance for loan losses is evaluated quarterly by management based on regular reviews of the collectability of the loans. The Company develops and documents the allowance for loan losses methodology at the portfolio segment level — the commercial loan portfolio is comprised of C&I, 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 allowance for loan losses 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 and troubled debt restructuring (“TDR”) 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. The following three different asset valuation measurement methods are available: (1) the present value of expected future cash flows, (2) the fair value of collateral less costs to sell, and (3) the loan's observable market price. The allowance for loan losses for collateral-dependent loans is determined based on the fair value of the collateral less costs to sell. For loans that are not collateral-dependent, the Company applies the present value of expected future cash flows valuation or the market value of the loan. When the loan is deemed uncollectible, it is the Company’s policy to promptly charge off the estimated credit losses. 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 allowance for credit losses for accrued interest receivables as the Company reverses accrued interest if a loan is on nonaccrual status. The allowance for loan losses is reported separately 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 estimate of credit losses will consider both the likelihood that funding will occur, and an estimate of 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 estimated 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 utilization 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 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 — ASU 2016-13 modifies the OTTI model for AFS debt securities to apply an allowance approach for credit impairment as opposed to permanently writing down the cost basis of the security. For each reporting period, 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, excluding accrued interest, of the AFS debt security. 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 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 securities’ ratings and other qualitative factors. For securities that are fully guaranteed by the U.S. government, or certain government enterprises, the Company believes that the credit loss exposure on these securities is remote and 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 to not 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 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, minus 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 — ASU 2016-13 replaces the concept of PCI accounting under ASC 310-30 Receivables - Loans and Debt Securities Acquired with Deteriorated Credit Quality with the concept of purchased financial assets with credit deterioration. The Company adopted ASU 2016-13 using the prospective transition approach for Purchased credit deteriorated (“PCD”) assets that were previously classified as PCI assets. PCD financial assets are defined as acquired individual financial assets (or groups with similar risk characteristics) that as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination. For PCD 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. Beginning January 1, 2020, for any asset designated as a PCD asset at the time of acquisition, the Company estimates and records an allowance for credit losses, which is added to the purchase price to establish the initial amortized cost basis of the financial asset. Hence, 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. Troubled Debt Restructurings — The Company has implemented various loan modification programs to provide its borrowers relief from the economic impacts of the Coronavirus Disease 2019 (“COVID-19”). In accordance with the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), the Company has elected to not apply TDR classification to any COVID-19 related loan modifications that were performed after March 1, 2020 to borrowers who were current as of December 31, 2019. For loans modified in response to the COVID-19 pandemic that do not meet the CARES Act criteria (e.g., current payment status as of December 31, 2019), the Company has applied the guidance included in “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customer Affected by the Coronavirus (Revised)” (the “Interagency Statement”) issued by the federal banking regulators on April 7, 2020. The Interagency Statement states that loan modifications performed in light of the COVID-19 pandemic, including loan payment deferrals that are up to six months in duration, that were granted to borrowers who were current as of the implementation date of a loan modification program or modifications granted under government mandated modification programs, are not TDRs. The delinquency of the loans modified under the CARES Act and Interagency Statement is frozen at the time of the modification, and interest income continues to be recognized over the contractual life of the loan. For more information on the Company's TDR accounting, see Note 1 — Summary of Significant Accounting Principles — Troubled Debt Restructurings to the Consolidated Financial Statements of the Company’s 2019 Annual Report on Form 10-K. Paycheck Protection Program — From April to August 2020, the Company accepted Paycheck Protection Program (“PPP”) applications and originated loans to qualified small businesses under the PPP established by the CARES Act. These loans are included in the C&I portfolio, carry an interest rate of 1%, and are 100% guaranteed by the Small Business Administration (“SBA”). No allowance for loan losses was recorded for these loans as of September 30, 2020. As of September 30, 2020, the Company funded over 7,400 SBA 7(a) approved PPP loans with an outstanding loan balance of $1.77 billion. The substantial majority of the Company’s PPP loans have a term of two years. The SBA paid the Company fees for processing PPP loans in the following amounts: (1) five percent for loans of not more than $350,000; (2) three percent for loans of more than $350,000 and less than $2,000,000; and (3) one percent for loans of at least $2,000,000. Loan processing fees paid to the Company by the SBA are accounted for as loan origination fees, where net deferred fees are recognized over the estimated life of the loan as a yield adjustment on the loans. Payments by borrowers on PPP loans begin ten months after the loan forgiveness covered period. Under the terms of the PPP, such loans are eligible to be forgiven if certain conditions are satisfied, in which case the SBA will make payments to the Company for the forgiven amounts. If a loan is paid off or forgiven by the SBA prior to its projected estimated life, the remaining unamortized deferred fees will be recognized as interest income in that period.
Fair Value Determination | Fair Value Determination 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. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy noted below is based on the quality and reliability of the information used to determine fair value. The fair value hierarchy gives the highest priority to quoted prices available in active markets and the lowest priority to prices derived from data lacking transparency. 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. The classification of assets and liabilities within the hierarchy is based on whether inputs to the valuation methodology used are observable or unobservable, and the significance of those inputs in the fair value measurement. 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.
Cash Flow Hedges | For cash flow hedges, the entire change in the fair value of the hedging instruments is recognized in AOCI and reclassified to earnings in the same period when the hedged cash flows impact earnings. Reclassified gains and losses on interest rate swaps are recorded in the same line item as the interest payments of the hedged long-term borrowings within Interest expense in the Consolidated Statements of Income.
Credit Quality Indicators | Credit Quality Indicators All loans are subject to the Company’s credit review and monitoring. For the commercial 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 majority of the consumer portfolio, payment performance or delinquency is the driving indicator for the risk ratings. For the Company’s internal credit risk ratings, each individual loan is given a risk rating of 1 through 10. Loans risk rated 1 through 5 are assigned an internal risk rating of “Pass”, with loans risk rated 1 being fully secured by cash or U.S. government and its agencies. Pass loans have sufficient sources of repayment to repay the loan in full, in accordance with all terms and conditions. Loans assigned a risk rating of 6 have potential weaknesses that warrant closer attention by management; these are assigned an internal risk rating of “Special Mention”. 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 of “Substandard”. 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 of “Doubtful”. Loans assigned a risk rating of 10 are uncollectable and of such little value that they are no longer considered bankable assets; these are assigned an internal risk rating of “Loss”. The Company reviews the internal risk ratings of its loan portfolio on a regular and ongoing basis, and adjusts the ratings based on changes in the borrowers’ financial status and the collectability of the loans.
Allowance for Loan Losses | Allowance for Loan Losses On January 1, 2020, the Company adopted ASU 2016-13 that establishes a single allowance framework for all financial assets measured at amortized cost and certain off-balance sheet credit exposures. It requires the measurement of the allowance for loan losses to be based on management’s best estimate of lifetime expected credit losses inherent in the Company’s relevant financial assets. Balance sheet information and results of operations for reporting periods beginning with January 1, 2020 are presented under ASC 326, while prior period comparisons continue to be presented under legacy GAAP. The process of the allowance for loan losses involves procedures to consider the unique risk characteristics of the portfolio segments. For each loan portfolio segment, the expected credit losses are estimated collectively for groups of loans with similar risk characteristics. For loans that do not share similar risk characteristics, the expected credit losses are estimated individually. Allowance for Collectively Evaluated Loans Quantitative Component — The allowance for loan losses is estimated using quantitative methods that consider a variety of factors such as historical loss experience, the current credit quality of the portfolio, as well as an economic outlook over the life of the loan. The Company incorporates forward-looking information using macroeconomic scenarios applied over the forecasted life of the loans. The forward-looking information is limited to the reasonable and supportable period. These macroeconomic scenarios 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 and upside scenarios reflecting possible worsening or improving economic conditions. A probability-weighted average of these macroeconomic scenarios over a reasonable and supportable forecast period is incorporated into the quantitative models. If the loans’ life extends beyond the reasonable and supportable forecast period, then historical experience is considered over the remaining life of the loans in estimation of the allowance for loan losses. Qualitative Component — The Company also 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 not limited to: •Loan growth trends; •The volume and severity of past due financial assets, and the volume and severity of adversely classified or rated financial assets; •The Company’s lending policies and procedures, including changes in lending strategies, underwriting standards, collection, write-off and recovery practices, •Knowledge of the borrower’s operations or the borrower’s standing in the community; •The quality of the Company’s credit review system; •The experience, ability and depth of the Company’s management, lending staff and other relevant staff; •The effect of other external factors such as the regulatory, legal and technological environments; and •Actual and expected changes in international, national, regional, and local economic and business conditions in which the Company operates, including the actual and expected conditions of various market segments. 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 |  | Internal risk rating; size and credit spread at origination, and time to maturity |  | Unemployment rate, and two and ten year treasury spread
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; delinquency status; maturity date; collateral value, and geographic location |  | Unemployment rate; GDP, and home price index
Other consumer |  | Historical loss experience |  | Immaterial (1)
(1)Macroeconomic variables are included in the qualitative estimate. Management updated the macroeconomic forecast used in its credit loss estimation process as of September 30, 2020, which reflected more stabilized economic conditions as a result of an improved macroeconomic forecast, compared with June 30, 2020. The improvements in the macroeconomic forecast used in the credit loss estimation reflected improvements in gross domestic product growth and unemployment rate forecasts. The Company also considered the economic uncertainty caused by the COVID-19 pandemic, U.S. monetary and fiscal responses to the pandemic, the expected impacts of lower oil prices and deteriorating credit trends on the oil & gas portfolio, among other assumptions. For the three and nine months ended September 30, 2020, there were no changes to the reasonable and supportable forecast period, and reversion to historical loss experience method. Allowance for Loan Losses for the Commercial Loan Portfolio — The Company’s C&I loan lifetime loss rate model estimates credit losses by estimating a 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 implicitly through the loan-level lifetime loss rate. For CRE loans, projected probability of defaults (“PDs”) and loss given defaults (“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. After a reasonable and supportable period, the forecast of future economic conditions reverts to long-run historical economic trends. In order to estimate the life of a loan under both models, the contractual term of the loan is adjusted for estimated prepayments, which are based on historical prepayment experience. Allowance for Loan Losses 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. After a reasonable and supportable period, the forecast of future economic conditions reverts to long-run historical economic trends. For other consumer loans, the Company uses a loss rate approach. In order to estimate the life of a loan, the contractual term of the loan is adjusted for estimated prepayments, which are based on historical prepayment experience. Qualitative Allowance for Collectively Evaluated Loans — 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. The allowance for loan losses as of September 30, 2020 also included qualitative adjustments for certain industry sectors, such as oil & gas, included as part of the C&I loan portfolio. Allowance for Individually Assessed Loans — When a loan no longer shares similar risk characteristics with other loans, such as in the case for certain nonaccrual or TDR loans, the Company estimates the allowance for loan losses on an individual loan basis. The allowance for loan losses 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; and (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 — When a loan is collateral dependent, the allowance is measured on an individual loan basis and is limited to the difference between the recorded value and fair value of the collateral less cost of disposal or sale.
Investments in Qualified Affordable Housing Partnerships, Net and Investments in Tax Credit and Other Investments, Net | The Company records its investments in qualified affordable housing partnerships, net, using the proportional amortization method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the amortization in Income tax expense on the Consolidated Statement of Income.Depending on the ownership percentage and the influence the Company has on the investments in tax credit and other investments, net, the Company applies the equity or cost method of accounting, or the measurement alternative as elected under ASU 2016-01 for equity investments without readily determinable fair value.
Variable Interest Entities | Variable Interest Entities The Company invests in unconsolidated limited partnerships and similar entities that construct, own and operate affordable housing, historic rehabilitation, wind and solar projects, of which the majority of such investments are variable interest entities (“VIEs”). As a limited partner in these partnerships, these investments are designed to generate a return primarily through the realization of federal tax credits and tax benefits. An unrelated third party is typically the general partner or managing member who has control over the significant activities of such investments. While the Company’s interest in some of the investments may exceed 50% of the outstanding equity interests, the Company does not consolidate these structures due to the general partner or managing member’s ability to manage the entity, which is indicative of power over them. The Company’s maximum exposure to loss in connection with these partnerships consist of the unamortized investment balance and any tax credits claimed that may become subject to recapture. Special purpose entities formed in connection with securitization transactions are generally considered VIEs. The Company is the servicer of multifamily residential loans it securitized in 2016. Because the Company does not have the power or hold a variable interest that could potentially be significant to this VIE, the multifamily securitization entity is not consolidated. A CLO is a VIE that purchases a pool of assets consisting primarily of non-investment grade corporate loans, and issues multiple tranches of notes to investors to fund the asset purchases and pay upfront expenses associated with forming the CLO. The Company serves as the collateral manager of a CLO that closed in the fourth quarter of 2019 and has retained substantially all of the investment grade-rated securities issued by the CLO. In accordance with GAAP, the Company does not consolidate the CLO as it does not hold interests that could potentially be significant to the CLO.
Goodwill and Core Deposit Intangibles | The Company assesses goodwill for impairment at the reporting unit level, equivalent to the same level as the Company’s business segments. This assessment is performed on an annual basis as of December 31 each year, or more frequently if events or circumstances, such as adverse changes in the economic or business environment, indicate there may be impairment. The Company organizes its operations into three reporting segments: (1) Consumer and Business Banking; (2) Commercial Banking; and (3) Other.Core deposit intangibles represent the intangible value of depositor relationships resulting from deposit liabilities assumed in various acquisitions and are included in Other assets on the Consolidated Balance Sheet. These intangibles are tested for impairment on an annual basis, or more frequently as events occur or current circumstances and conditions warrant.
Amortization Expense of Core Deposit Intangibles | The Company amortizes the core deposit intangibles based on the projected useful lives of the related deposits.
Litigation | Litigation — The Company is a party to various legal actions arising in the 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. Thus, the Company’s exposure and ultimate losses may be higher, and possibly significantly more than the amounts accrued.
Revenue Recognition | Generally, the Company recognizes revenue from contracts with customers when it satisfies its performance obligations. The Company’s performance obligations are typically satisfied as services are rendered. The Company generally records contract liabilities, or deferred revenue, when payments from customers are received or due in advance of providing services. The Company records contract assets when services are provided to customers before payment is received or before payment is due.
Share-based Compensation | The amount of performance-based RSUs that are eligible to vest is determined at the end of each performance period, and is then added together as the total number of performance shares to vest. Performance-based RSUs cliff vest three years from the date of each grant.Compensation costs for the time-based awards that will be settled in shares of the Company’s common stock are based on the quoted market price of the Company’s common stock at the grant date. Compensation costs for certain time-based awards that will be settled in cash are adjusted to fair value based on changes in the share price of the Company’s common stock up to the settlement date. Compensation costs associated with performance-based RSUs are based on grant date fair value which considers both market and performance conditions, and is subject to subsequent adjustments based on the changes in the Company’s projected outcome of the performance criteria. Compensation costs of both time-based and performance-based awards are estimated based on awards ultimately expected to vest, and recognized on a straight-line basis from the grant date until the vesting date of each grant.
