Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations— Hope Bancorp, Inc. (“Hope Bancorp” on a parent-only basis and the “Company” on a consolidated basis), headquartered in Los Angeles, California, is the holding company for Bank of Hope (the “Bank”). The Bank has branches in California, New York, Illinois, Washington, Texas, New Jersey, Virginia, and Alabama, as well as loan production offices in Atlanta, Dallas, Denver, Portland, Seattle, Southern California, and Northern California. Hope Bancorp is a corporation organized under the laws of the state of Delaware and a bank holding company registered under the Bank Holding Company Act of 1956, as amended. The Bank is a California-chartered bank and its deposits are insured by the FDIC to the extent provided by law. The Company specializes in core business banking products for small and medium-sized businesses, with an emphasis in commercial real estate and business lending, SBA lending, and international trade financing. Principles of Consolidation— The accounting and reporting policies of the Company are in accordance with accounting principles generally accepted in the United States of America and conform to practices within the banking industry. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, principally the Bank. Intercompany transactions and balances are eliminated in consolidation. Cash and Cash Equivalents —Cash and cash equivalents include cash and due from banks, interest-earning deposits, and federal funds sold, which have original maturities less than 90 days. The Company may be required to maintain reserve and clearing balances with the Federal Reserve Bank under the Federal Reserve Act. The reserve and clearing requirement balance was $0 at December 31, 2020 and 2019. Net cash flows are reported for customer loan and deposit transactions, investment transactions, federal funds purchased, deferred income taxes, and other assets and liabilities. Interest-Bearing Deposits in Other Financial Institutions —Interest-bearing deposits in other financial institutions are comprised of the Company’s investments in certificates of deposits that have original maturities greater than 90 days. Securities— Securities are classified and accounted for as follows: (i) Securities that the Company has the positive intent and ability to hold to maturity are classified as “held to maturity” and reported at amortized cost. At December 31, 2020 and 2019, the Company did not own securities in this category; (ii) Securities are classified as “available for sale” when they might be sold before maturity and are reported at fair value. Unrealized holding gains and losses are reported as a separate component of stockholders’ equity in accumulated other comprehensive income, net of taxes. Accreted discounts and amortized premiums on securities are included in interest income using the interest method, and realized gains or losses related to sales of securities recorded on trade date and are calculated using the specific identification method, without anticipating prepayments, except for mortgage-backed securities where prepayments are expected. On January 1, 2020, the Company adopted ASU 2016-13 and implemented the CECL methodology for allowance for credit losses on its investment securities available for sale. The new CECL methodology replaces the other-than-temporary impairment model that previously existed. The Company did not have a day 1 allowance impact attributable to its investment securities portfolio and did not have an allowance for credit losses as of December 31, 2020. The Company has elected to exclude accrued interest from the amortized cost of its investment securities available for sale. The Company evaluates securities in unrealized loss position for impairment related to credit losses on at least a quarterly basis. Securities in unrealized loss positions are first assessed as to whether the Company intend to sell, or if it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If one of the criteria is met, the security’s amortized cost basis is written down to fair value through current earnings. For securities that do not meet these criteria, the Company evaluates whether the decline in fair value resulted from credit losses or other factors. In evaluating whether a credit loss exists, the Company has set up an initial filter for impairment triggers. Once the quantitative filters have been triggered, the securities are placed on a watch list and an additional assessment is performed to identify whether a credit impairment exists. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security and the issuer, among other factors. If this assessment indicates that a credit loss exists, the Company compares the present value of cash flows expected to be collected from the security with the amortized cost basis. If the present value of cash flows expected to be collected is less than the amortized cost basis for the security, a credit loss exists and an allowance for credit losses is recorded, limited to the amount that the fair value of the security is less than its amortized cost basis. Unrealized losses that have not been recorded through an allowance for credit losses is recognized in other comprehensive income, net of applicable taxes. No allowance for credit losses for available for sale securities was recorded at December 31, 2020. Equity Investments —On January 1, 2018, the Company adopted ASU 2016-01 and reclassified its mutual funds, equity stock, correspondent bank stock, Community Development Financial Institutions Fund (“CDFI”) investments, and Community Reinvestment Act (“CRA”) investments as equity investments. The Company’s mutual funds are considered equity investments with readily determinable fair values and changes to fair value are recorded in other noninterest income. The Company sold all of its investment in equity stock in 2019. The Company’s investment in correspondent bank stock, CDFI investments, and CRA investments are equity investments without readily determinable fair values. Equity investments without readily determinable fair values are measured at cost, less impairment, and are adjusted for observable price changes which is recorded in noninterest income. Derivative Financial Instruments and Hedging Transactions —As part of the Company’s asset and liability management strategy, the Company uses derivative financial instruments, such as interest rate swaps, risk participation agreements, and caps and floors, with the overall goal of minimizing the impact of interest rate fluctuations on net interest margin. The Company’s interest rate swaps and caps involve the exchange of fixed rate and variable rate interest payment obligations without the exchange of the underlying notional amounts and are therefore accounted for as stand-alone derivatives. Derivative instruments are included in other assets or accrued expenses and other liabilities on the Consolidated Balance Sheet at fair value. At the inception of the derivative contract, the Company designates the derivative as (1) a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (2) an instrument with no hedging designation (“stand-alone derivative”). For a cash flow hedge, the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, in noninterest income. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. The related cash flows are recognized on the cash flows from operating activities section on the Consolidated Statement of Cash Flows. Residential mortgage loans funded with interest rate lock commitments and forward commitments for the future delivery of mortgage loans to third party investors, are both considered derivatives. The Company accounts for loan commitments related to the origination of mortgage loans that will be held-for-sale as derivatives at fair value on the balance sheet, with changes in fair value recorded in earnings in the period in which the changes occur. As part of the Company’s overall risk management, the Company’s Asset Liability Committee, which meets monthly, monitors and measures interest rate risk and the sensitivity of assets and liabilities to interest rate changes, including the impact of derivative transactions. The Company formally documents all relationships between derivatives and hedged items, as well as the risk-management objective and strategy for undertaking various hedge transactions. This documentation includes linking cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used in hedging transactions are highly effective in offsetting changes in cash flows of the hedged items. The Company discontinues hedge accounting prospectively when it is determined that (1) the derivative is no longer effective in offsetting changes in the cash flows of the hedged item (2) the derivative expires, is sold, or terminated (3) the derivative instrument is de-designated as a hedge because the forecasted transaction is no longer probable of occurring (4) a hedged firm commitment no longer meets the definition of a firm commitment (5) or management otherwise determines that designation of the derivative as a hedging instrument is no longer appropriate. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transaction is still expected to occur, changes in value that were accumulated in other comprehensive income are amortized or accreted into earnings over the same periods which the hedged transactions will affect earnings. Company enters into risk participation agreements with outside counterparties for interest rate swaps related to loans in which it is a participant. The risk participation agreements provide credit protection to the financial institution should the borrower fail to perform on its interest rate derivative contract. Risk participation agreements are credit derivatives not designated as hedges. Credit derivatives are not speculative and are not used to manage interest rate risk in assets or liabilities. Changes in the fair value in credit derivatives are recognized directly in earnings. The fee received, less the estimate of the loss for credit exposure, was recognized in earnings at the time of the transaction. Loans Held for Sale —Residential mortgage loans that the Company has the intent to sell prior to maturity have been designated as held for sale at origination and are recorded at the lower of cost or fair value, on an aggregate basis. Certain loans which were originated with the intent to hold to maturity are subsequently transferred to held for sale once there is an intent to sell the loan. A valuation allowance is established if the aggregate fair value of such loans is lower than their cost and charged to earnings. Gains or losses recognized upon the sale of loans are determined on a specific identification basis. Loan transfers are accounted for as sales when control over the loan has been surrendered. Control over such loans is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Company does not maintain control over the transferred assets through an agreement to repurchase them before their maturity. Loans— Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the amount of unpaid principal, adjusted for net deferred fees and costs, premiums and discounts, purchase accounting fair value adjustments, and allowance for credit losses. Interest income is accrued on the unpaid principal balance. Nonrefundable loan origination fees and certain direct origination costs are deferred and recognized in interest income using the level-yield method over the life of the loan. Interest on loans is credited to income as earned and is accrued only if deemed collectible. The loan portfolio consists of four segments: real estate, commercial business, residential mortgage, and consumer and other loans. Real estate loans are extended for the purchase and refinance of commercial real estate and are generally secured by first deeds of trust and are collateralized by residential or commercial properties. Commercial business loans are loans provided to businesses for various purposes such as for working capital, purchasing inventory, debt refinancing, business acquisitions, international trade finance activities, and other business related financing needs and also include warehouse lines of credit, syndicated loans, and SBA Paycheck Protection Program (“PPP”) loans. Residential mortgage loans are extended for personal, family, or household use and are secured by a mortgage or deed of trust. Consumer and other loans consist of home equity, credit card, and other personal loans. On January 1, 2020, the Company adopted ASU 2016-13, or CECL, using the modified retrospective method for all of its loans measured at amortized cost. With the adoption of CECL, the Company reassessed its loan portfolio segments and classes of loans receivable and made changes based on the new allowance for credit losses methodology. As a result, the Company now discloses residential mortgage loans as a separate segment and class of receivable. Trade finance loans, which were previously disclosed as a distinct segment and class of receivable, are now combined with commercial business loans. Prior period balances have been reclassified to conform with the current presentation. Generally, loans are placed on nonaccrual status and the accrual of interest is discontinued if principal or interest payments become 90 days past due and/or management deems the collectability of the principal and/or interest to be in question. Loans to a customer whose financial condition has deteriorated are considered for nonaccrual status whether or not the loan is 90 days or more past due. Generally, payments received on nonaccrual loans are recorded as principal reductions. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Other loan fees and charges, representing service costs for the prepayment of loans, for delinquent payments, or for miscellaneous loan services, are recorded as income when collected. The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including, but not limited to, current financial information, historical payment experience, credit documentation, public information, and current economic trends. Homogeneous loans (i.e., home mortgage loans, home equity lines of credit, overdraft loans, express business loans, and automobile loans) are not risk rated and credit risk is analyzed largely by the number of days past due. This analysis is performed at least on a quarterly basis: • Pass: Loans that meet a preponderance or more of the Company’s underwriting criteria and that evidence an acceptable level of risk. • Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. • Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the borrower or by the collateral pledged, if any. Loans in this classification have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. • Doubtful/Loss: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or repayment in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Allowance for Credit Losses (“ACL”) —The Company calculates its ACL by estimating expected credit losses on a collective basis for loans that share similar risk characteristics. Loans that do not share similar risk characteristics with other loans are evaluated for credit losses on an individual basis. The Company uses a combination of a modeled and non-modeled approach that incorporates current and future economic conditions to estimate lifetime expected losses on a collective basis. The Company uses Probability of Default (“PD”), Loss Given Default (“LGD”), and Exposure at Default (“EAD”) methodologies with quantitative factors and qualitative considerations in calculation of the allowance for credit losses for collectively assessed loans. The Company uses a reasonable and supportable period of 2 years at which point loss assumptions revert back to historical loss information by means of 1 year reversion period. For a discussion of the Company’s former incurred loss allowance for loan losses methodology, please refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The ACL for the Company’s construction, credit card, and certain consumer loans is calculated based on a non-modeled approach utilizing historical loss rates to estimate losses. A non-modeled approach was chosen for these loans as fewer data points exist which could result in high levels of estimated loss volatility under a modeled approach. Materiality was another factor in using a non-modeled approach for these loans as in aggregate, non-modeled loans represented approximately than 2% of the Company’s total loan portfolio as of December 31, 2020. With the adoption of CECL, the Company formed an Economic Forecast Committee (“EFC”) to review economic forecast scenarios that are incorporated in the Company’s ACL. The EFC reviews multiple scenarios put together by an independent third party and chooses a single scenario that best aligns with management’s expectation of future economic conditions. The forecast scenarios contain certain macroeconomic variables that are incorporated into the Company’s modeling process, including GDP, unemployment rates, interest rates, and commercial real estate prices. As of December 31, 2020, the Company chose a forecast scenario that incorporates the effect of the COVID-19 pandemic into estimates of future economic conditions. The allowance for credit losses at December 31, 2020 utilizes the Moody’s Baseline scenario, as well as more specific information, including updated CRE market data which reflects deterioration primarily in the hospitality industry. Additionally, in order to systematically quantify the credit risk impact of other trends and changes within the loan portfolio that may not be capture by the modeled and non-modeled approach, the Company utilizes qualitative adjustments to estimate total expected losses. The parameters for making adjustments are established under a Credit Risk Matrix that provides different possible scenarios for each of the factors below. The Credit Risk Matrix and the possible scenarios enable the Bank to qualitatively adjust the allowance for credit losses by as much as 25 basis points for each loan type pool. This matrix considers the following seven factors, which are patterned after the guidelines provided under the Federal Financial Institutions Examination Council (“FFIEC”) Interagency Policy Statement on the Allowance for Loan and Lease Losses, updated to reflect the application of the CECL methodology: • Changes in lending policies and procedures, including underwriting standards and collection, charge-off, and recovery practices; • Changes in the nature and volume of the loan portfolio; • Changes in the experience, ability and depth of lending management and staff; • Changes in the trends of the volume and severity of past due loans, Classified Loans, nonaccrual loans, troubled debt restructurings and other loan modifications; • Changes in the quality of the loan review system and the degree of oversight by the Directors; • The existence and effect of any concentrations of credit and changes in the level of such concentrations; and • The effect of other external factors, such as competition, legal and regulatory requirements, and others that have an impact on the level of estimated losses in the Company’s loan portfolio. For loans which do not share similar risk characteristics such as nonaccrual and TDR loans above $500 thousand, the Company evaluates these loans on an individual basis in accordance with ASC 326. These nonaccrual and TDR loans are considered to have different risk profiles than performing loans and therefore are evaluated separately. The Company collectively assesses TDRs and nonaccrual loans with balances below $500 thousand along with the performing and accrual loans in order to reduce the operational burden of individually assessing small TDR and nonaccrual loans with immaterial balances. For individually assessed loans, the ACL is measured using either 1) the present value of future cash flows discounted at the loan’s effective interest rate; 2) the loan’s observable market price; or 3) the fair value of the collateral, if the loan is collateral dependent. For the collateral dependent loans, the Company obtains a new appraisal to determine the fair value of underlying loan collateral. The appraisals are based on an “as-is” valuation. To ensure that appraised values remain current, the Company either obtains updated appraisals every twelve months from a qualified independent appraiser or an internal evaluation of the collateral is performed by qualified personnel. If the third party market data indicates that the value of the collateral property has declined since the most recent valuation date, management adjusts the value of the property downward to reflect current market conditions. If the fair value of the collateral is less than the amortized balance of the loan, the Company recognizes an ACL with a corresponding charge to the provision for credit losses. As of December 31, 2020, the Company recorded $1.0 million in ACL on its loan accrued interest receivable balances attributable to COVID-19 payment deferral modifications. The ACL was estimated by using the same loss ratios calculated for the underlying loans under the CECL allowance methodology and applying the ratios to the accrued interest portion of modified loans. Total accrued interest on the Consolidated Statement of Financial Condition is presented net of any ACL and changes to the accrued interest ACL is recorded in credit related expenses. TDR loans are individually evaluated in accordance with ASC 310 and ASC 326. The concessions may be granted in various forms, including reduction in the stated interest rate, reduction in the amount of principal amortization, forgiveness of a portion of a loan balance or accrued interest, or extension of the maturity date. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed on the probability that the borrower will be in payment default on their debt in the foreseeable future without the modification. This evaluation is performed under the Bank’s internal underwriting policy. TDR loans on accrual status are comprised of loans that were accruing at the time of restructuring and for which the Company anticipates full repayment of both principal and interest under the restructured terms. TDR loans that are on nonaccrual status can be returned to accrual status after a period of sustained performance, generally determined to be six months of timely payments as modified. Sustained performance includes the periods prior to the modification and if the prior performance met or exceeded the modified terms. The CARES Act provides banks the option to temporarily suspend certain requirements under U.S. GAAP related to TDR accounting for a limited period of time to account for the effects of COVID-19 if (i) the loan modification is made between March 1, 2020 and the earlier of January 1, 2022 or 60 days after the end of the coronavirus emergency declaration and (ii) the applicable loan was not more than 30 days past due as of December 31, 2019. As such, all modified loans that met the criteria outlined within Section 4013 of the CARES Act were not classified as TDR loans as of December 31, 2020, unless the loans were TDR prior to the COVID-19 modification. Purchase Credit Deteriorated (“PCD”) — PCD is a classification of purchased financial assets for which there has been a more-than insignificant deterioration in credit quality since origination. The Company adds the allowance for credit losses at the date of acquisition to the purchase price to determine the initial amortized cost basis for purchased financial assets with credit deterioration. Any noncredit discount or premium resulting from acquiring loans with credit deterioration shall be allocated to each individual asset. At the acquisition date, the initial allowance for credit losses is determined on a collective basis and is allocated to individual assets to appropriately allocate any noncredit discount or premium. The Company accounts for purchased financial assets that do not have a more-than-insignificant deterioration in credit quality since origination in a manner consistent with originated financial assets. After initial recognition, the Company shall treat PCD assets like all other loans and apply one of the impairment models under CECL for instruments measured at amortized cost. The noncredit discount shall be amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision for credit losses. OREO —OREO, which represents real estate acquired through foreclosure in satisfaction of commercial and real estate loans, is stated at fair value less estimated selling costs of the real estate. Loan balances in excess of the fair value of the real estate acquired at the date of acquisition are charged to the allowance for credit losses. Any subsequent operating expenses or income, reduction in estimated fair values, and gains or losses on disposition of such properties are charged or credited to current operations. For the year ended December 31, 2020, the Company foreclosed on properties with an aggregate carrying value of $2.9 million. The Company recorded $4.3 million in net valuation losses subsequent to the foreclosures during the year ended December 31, 2020, and the Company sold OREO properties for total proceeds of $2.5 million during the year. FHLB Stock —The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. Premises and Equipment —Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization of premises and equipment are computed on the straight-line method over the following estimated useful lives: • Buildings - 15 to 39 years • Furniture, fixture, and equipment - 3 to 10 years • Computer equipment - 1 to 5 years • Computer software - 1 to 5 years • Leasehold improvement - life of lease or improvements, whichever is shorter BOLI —The Company has purchased life insurance policies on certain key executives and directors. BOLI is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Investments in Affordable Housing Partnerships —The Company owns limited partnership interests in projects of affordable housing for lower income tenants. Under the equity method of accounting, the annual amortization is based on the estimated tax deduction amounts the bank would receive in the year. The carrying value of such investments and commitments to fund investment in affordable housing is recorded as “Investments in affordable housing partnerships” in the Consolidated Statement of Financial Condition. Commitments to fund investments in affordable housing is also included in this line items but is also grossed up and recorded as a liability. Leases —operating lease right-of-use (“ROU”) assets represent the Company’s right to use the underlying asset during the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the future lease payments using the Company’s incremental borrowing rate. The Company calculates its incremental borrowing rate by adding a spread to the FHLB borrowing interest rate at a given period. The Company does not capitalize short-term leases, which are leases with terms of twelve months or less. ROU assets and related operating lease liabilities are remeasured when lease terms are amended, extended, or when management intends to exercise available extension options. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term and is recorded in occupancy expense in the consolidated statements of income. The Company’s occupancy expense also includes variable lease costs which is comprised of the Company's share of actual costs for utilities, common area maintenance, property taxes, and insurance that are not included in lease liabilities and are expensed as incurred. Variable lease costs also include rent escalations based on changes to indices, such as the Consumer Price Index. Goodwill and Intangible Assets— Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any non-controlling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized but tested for impairment at least annually. In accordance with ASC 350 “ Intangibles - Goodwill and Other ”, the Company makes a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying the two-step goodwill impairment test. If management concludes that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, the step 1 impairment test is bypassed. Management assessed the qualitative factors related to goodwill as of December 31, 2020 and determined a Step 1 fair value assessment was required. Based on this assessment, management determined that goodwill was not impaired at December 31, 2020. Goodwill is also tested for impairment on an interim basis if circumstances change or an event occurs between annual tests that would more likel

Receivables [Abstract]
Loans Receivable and the Allowance for Credit Losses	LOANS RECEIVABLE AND THE ALLOWANCE FOR CREDIT LOSSES The following is a summary of loans by major category at December 31, 2020 and 2019: December 31, 2020 December 31, 2019 Loan portfolio composition (Dollars in thousands) Real estate loans: Residential $ 54,795 $ 52,558 Commercial 8,425,959 8,316,470 Construction 291,380 295,523 Total real estate loans 8,772,134 8,664,551 Commercial business 4,157,787 2,721,183 Residential mortgage 582,232 835,188 Consumer and other 51,060 55,085 Total loans outstanding 13,563,213 12,276,007 Allowance for credit losses (206,741) (94,144) Loans receivable, net of allowance for credit losses $ 13,356,472 $ 12,181,863 The Company segments its loan portfolio in four major categories including real estate loans, commercial business loans, residential mortgage loans, and consumer and other loans. Real estate loans are extended for the purchase and refinance of commercial real estate and are generally secured by first deeds of trust and are collateralized by residential or commercial properties. Commercial business loans are loans provided to businesses for various purposes such as for working capital, purchasing inventory, debt refinancing, business acquisitions, international trade finance activities, and other business related financing needs and also include warehouse lines of credit, syndicated loans, and SBA Paycheck Protection Program (“PPP”) loans. Residential mortgage loans are extended for personal, family, or household use and are secured by a mortgage or deed of trust. Consumer and other loans consist of home equity, credit card, and other personal loans. The Company originated $480.2 million in SBA PPP loans with the majority of loans originated during the second quarter of 2020. As of December 31, 2020, the balance of SBA PPP loans was $452.7 million. The Company does not set aside an ACL on its SBA PPP loans as the loans are fully guaranteed by the SBA as permitted by Section 1102 of the CARES Act. On January 1, 2020, the Company adopted ASU 2016-13, or CECL, using the modified retrospective method for all of its loans measured at amortized cost. With the adoption of CECL, the Company reassessed its loan portfolio segments and classes of loans receivable and made changes based on the new allowance for credit losses methodology. As a result, the Company now discloses residential mortgage loans as a separate segment and class of receivable. Trade finance loans, which were previously disclosed as a distinct segment and class of receivable, are now combined with commercial business loans. Prior period balances have been reclassified to conform with the current presentation. The Company elected to exclude accrued interest from the amortized cost basis of loans. Accrued interest receivable on loans at December 31, 2020 and 2019 totaled $54.6 million and $26.2 million, respectively. The increase in accrued interest receivables was due to COVID-19 payment deferral modifications provided to customers in the second half of 2020. The tables below details the activity in the allowance for credit losses by portfolio segment for the years ended December 31, 2020 and 2019.

The ACL represents management’s best estimate of future lifetime expected losses on its held for investment loan portfolio. The Company calculates its ACL by estimating expected credit losses on a collective basis for loans that share similar risk characteristics. Loans that do not share similar risk characteristics with other loans are evaluated for credit losses on an individual basis. The Company uses a combination of a modeled and non-modeled approach that incorporates current and future economic conditions to estimate lifetime expected losses on a collective basis. The Company uses Probability of Default (“PD”), Loss Given Default (“LGD”), and Exposure at Default (“EAD”) methodologies with quantitative factors and qualitative considerations in calculation of the allowance for credit losses for collectively assessed loans. The Company uses a reasonable and supportable period of 2 years at which point loss assumptions revert back to historical loss information by means of 1 year reversion period. Due to the volatility that arose from the COVID-19 pandemic, the Company assessed whether it would appropriate to shorten the reasonable and supportable period. However, the Company chose to keep the reasonable and supportable period at 2 years as a shorter period was estimated to result in large reductions in ACL which would not be reflective of the economic deterioration and future uncertainty caused by pandemic. The Company utilizes a baseline forecast scenario published by a third party that incorporates macroeconomic variables including GDP, unemployment rates, interest rates, and commercial real estate prices to project an economic outlook. The forecast scenario is utilized to estimate losses during the reasonable and supportable period. Changes in these assumptions and forecasts could significantly affect the Company’s estimate of future credit losses. See Note 1 “Significant Accounting Policies” of the Notes to Consolidated Financial Statements for further discussion of the Company’s ACL methodology. The increase in ACL for the year ended December 31, 2020 compared to December 31, 2019 was due to the adoption of CECL and due to the COVID-19 pandemic which had significant impact on current and projected macroeconomic variables. The Baseline forecast scenario used in the December 31, 2020 ACL calculation includes elevated unemployment, which is forecasted to increase slightly in 2021 and remain above 5% until 2023. CRE pricing is projected to decline and result in negative growth up to the fourth quarter of 2022 while GDP growth is expected to increase modestly in 2021 and 2022 after which GDP is projected to trend downward. The Company maintains a separate ACL for its off-balance sheet unfunded loan commitments. The Company uses a funding rate to allocate the allowance to undrawn exposures. This funding rate is used as a credit conversion factor to capture how much undrawn can potentially become drawn at any point. The funding rate is determined based on a lookback period of 8 quarters. Credit loss is not estimated for off-balance sheet credit exposures that are unconditionally cancellable by the Company. As of December 31, 2020 and 2019, the reserves for unfunded commitments recorded in other liabilities was $1.3 million and $636 thousand, respectively. For the years ended December 31, 2020 and 2019, the Company recorded additional reserves for unfunded commitments recorded in credit related expenses totaling $660 thousand and recorded a reduction in reserve for unfunded commitments totaling $100 thousand, respectively. Generally, loans are placed on nonaccrual status if principal and/or interest payments become 90 days or more past due and/or management deems the collectability of the principal and/or interest to be in question, as well as when required by regulatory requirements. Loans to customers whose financial conditions have deteriorated are considered for nonaccrual status whether or not the loan is 90 days or more past due. Generally, payments received on nonaccrual loans are recorded as principal reductions. Loans are returned to accrual status only when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The Company does not recognize interest income while loans are on nonaccrual status. Interest income reversals due to loans being placed on nonaccrual status was $1.1 million and $1.4 million for the year ended December 31, 2020 or 2019, respectively. The tables below represent the recorded investment of nonaccrual loans and loans past due 90 or more days and still on accrual status by class of loans and broken out by loans with a recorded ACL and those without a recorded ACL as of December 31, 2020 and total nonaccrual loans and loans past due 90 or more days and still on accrual status by class of loans as of December 31, 2019.

The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes all loans with the exception of homogeneous loans, or loans that are evaluated together in pools of similar loans (i.e., home mortgage loans, home equity lines of credit, overdraft loans, express business loans, and automobile loans). Homogeneous loans are not risk rated and credit risk is analyzed largely by the number of days past due. This analysis is performed at least on a quarterly basis.

These modifications are either temporary in nature (“temporary modifications”) or are more substantive. The temporary modifications generally consist of interest only payments for a three six TDR loans are individually evaluated in accordance with ASC 310 and ASC 326. The concessions may be granted in various forms, including reduction in the stated interest rate, reduction in the amount of principal amortization, forgiveness of a portion of a loan balance or accrued interest, or extension of the maturity date. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed on the probability that the borrower will be in payment default on their debt in the foreseeable future without the modification. This evaluation is performed under the Bank’s internal underwriting policy. At December 31, 2020, total TDR loans were $51.6 million compared to $46.7 million at December 31, 2019. The balance of loans with modified terms due to COVID-19 as of December 31, 2020 totaled $1.38 billion. The majority of these loans were modified in accordance with Section 4013 of the CARES Act. The CARES Act provides banks the option to temporarily suspend certain requirements under U.S. GAAP related to TDR for a limited period of time to account for the effects of COVID-19 if (i) the loan modification is made between March 1, 2020 and the earlier of January 1, 2022 or 60 days after the end of the coronavirus emergency declaration and (ii) the applicable loan was not more than 30 days past due as of December 31, 2019. As such, all modified loans that met the criteria outlined within Section 4013 of the CARES Act were not classified as TDR loans as of December 31, 2020, unless the loans were TDR prior to the COVID-19 modification. As of December 31, 2020, real estate loans accounted for a little less than 95% of the loans modified due to hardship from the COVID-19 pandemic. The modifications consisted of full payment deferrals, interest only payments, and a hybrid of full payment deferrals for a period of time followed by interest only payments. The modifications were granted mostly for periods from 3 to 9 months.

TDR loans that are on nonaccrual status can be returned to accrual status after a period of sustained performance, generally determined to be six months of timely payments as modified. Sustained performance includes the periods prior to the modification if the prior performance met or exceeded the modified terms. TDR loans on accrual status at December 31, 2020 were comprised of 33 commercial real estate loans totaling $25.8 million, 25 commercial business loans totaling $11.4 million and 16 consumer and other loans totaling $172 thousand.

The Company expects that TDR loans on accrual status as of December 31, 2020, which were all performing in accordance with their restructured terms, to continue to comply with the restructured terms because of the reduced principal or interest payments on these loans. TDR loans that were restructured at market interest rates and had sustained performance as agreed under the modified loan terms may be reclassified as non-TDR after each year end but are reserved for under ASC 310-10. The Company recorded an allowance for credit losses of $4.8 million, $3.1 million, and $3.0 million on TDR loans as of December 31, 2020, 2019, and 2018, respectively.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangibles Assets	GOODWILL AND OTHER INTANGIBLE ASSETS The carrying amount of the Company’s goodwill as of December 31, 2020 and 2019 was $464.5 million. Goodwill represents the excess of the purchase price over the sum of the estimated fair values of the tangible and identifiable intangible assets acquired less the estimated fair value of the liabilities assumed. Goodwill has an indefinite useful life and is evaluated for impairment annually or more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. Goodwill is not amortized for book purposes and is not tax deductible. In 2020, the Company adopted ASU 2017-04 which simplifies the current goodwill impairment testing to eliminate Step 2 from the current provisions. Under the new guidance, an entity should perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying value and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. An entity still has the option to perform the quantitative assessment for a reporting unit to determine if a quantitative impairment test is necessary. Due to the recent COVID-19 pandemic, future expected economic performance has deteriorated substantially. In addition, U.S. equity markets experienced a significant decline since the first quarter of 2020. In line with these trends, the Company’s stock price also experienced a large reduction during the year ended December 31, 2020 where it continued to trade below the Company’s tangible book value. These factors contributed to the Company performing a goodwill impairment analysis for each quarter in 2020. The Company determined that a Step 1 goodwill impairment analysis was warranted as of December 31, 2020. The Company performed a Step 1 fair value assessment and determined that goodwill was not impaired as of December 31, 2020 as the fair value of the reporting unit exceeded the book value. As the Company operates as a single reporting unit, the fair value of the Company as a whole was estimated. Therefore, there was no impairment of goodwill recorded during the year ended December 31, 2020. Core deposit intangible assets are amortized over their estimated lives, which range from seven As of December 31, 2020 As of December 31, 2019 Core deposit intangibles related to: Amortization Gross Amount Accumulated Amortization Carrying Amount Accumulated Amortization Carrying Amount (Dollars in thousands) Center Financial 7 years $ 4,100 $ (4,100) $ — $ (4,100) $ — Pacific International Bank 7 years 604 (604) — (602) 2 Foster Bankshares 10 years 2,763 (2,322) 441 (2,120) 643 Wilshire Bancorp 10 years 18,138 (8,871) 9,267 (6,950) 11,188 Total $ 25,605 $ (15,897) $ 9,708 $ (13,772) $ 11,833 Total amortization expense on core deposit intangibles was $2.1 million and $2.2 million for the years ended December 31, 2020 and 2019, respectively.

Leases [Abstract]
Leases	LEASES On January 1, 2019, the Company adopted ASU 2016-02, “Leases (Topic 842)”, using the modified retrospective approach under ASC 842. The Company’s operating leases are real estate leases which are comprised of bank branches, loan production offices, and office spaces with remaining lease terms ranging from 1 year to 10 years as of December 31, 2020. Certain lease arrangements contain extension options which are typically around 5 years. As these extension options are not generally considered reasonably certain of exercise, they are not included in the lease term. As of December 31, 2020, the Company did not have any finance leases. Operating lease right-of-use (“ROU”) assets represent the Company’s right to use the underlying asset during the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using the Company’s incremental borrowing rate at the lease commencement date. The Company’s occupancy expense also includes variable lease costs which is comprised of the Company's share of actual costs for utilities, common area maintenance, property taxes, and insurance that are not included in lease liabilities and are expensed as incurred. Variable lease costs also include rent escalations based on changes to indices, such as the Consumer Price Index. The table below summarizes the Company’s net lease cost: Year Ended December 31, 2020 December 31, 2019 (Dollars in thousands) Operating lease cost $ 15,554 $ 16,039 Variable lease cost 3,227 3,397 Short term lease cost — 9 Sublease income (786) (664) Net lease cost $ 17,995 $ 18,781 Rent expense for the years ended December 31, 2020 and 2019 was $18.6 million and $18.7 million, respectively. The Company uses its incremental borrowing rate to present value lease payments in order to recognize a ROU asset and the related lease liability. The Company calculates its incremental borrowing rate by adding a spread to the FHLB borrowing interest rate at a given period. The following table summarizes supplemental balance sheet information related to operating leases: Year Ended December 31, 2020 December 31, 2019 (Dollars in thousands) Operating leases Operating lease right-of-use assets $ 47,653 $ 58,593 Current portion of long-term lease liabilities 13,689 12,807 Long-term lease liabilities 38,341 47,699 Weighted-average remaining lease term - operating leases 5.21 years 5.83 years Weighted-average discount rate - operating leases 2.97 % 3.09 % In December 2020, the Company wrote off $1.8 million in operating lease right-of-use assets resulting from branch consolidation of five locations.

Subordinated Debentures and Convertible Notes	SUBORDINATED DEBENTURES AND CONVERTIBLE NOTES Subordinated Debt At December 31, 2020, the Company had nine wholly-owned subsidiary grantor trusts that had issued $126.0 million of pooled trust preferred securities. Trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in the indentures. The trusts used the net proceeds from the offering to purchase a like amount of subordinated debentures of the Company (the “Debentures”). The Debentures are the sole assets of the trusts. The Company’s obligations under the Debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the trusts. The trust preferred securities are mandatorily redeemable upon the maturity of the Debentures, or upon earlier redemption as provided in the indentures. The Company has the right to redeem the Debentures in whole (but not in part) on a quarterly basis at a redemption price specified in the indentures plus any accrued but unpaid interest to the redemption date. The Company also has a right to defer consecutive payments of interest on the debentures for up to five years. The following table is a summary of trust preferred securities and Debentures at December 31, 2020: Issuance Trust Issuance Trust Preferred Carrying Value Rate Current Maturity (Dollars in thousands) Nara Capital Trust III 06/05/2003 $ 5,000 $ 5,155 Variable 3.400% 06/15/2033 Nara Statutory Trust IV 12/22/2003 5,000 5,155 Variable 3.125% 01/07/2034 Nara Statutory Trust V 12/17/2003 10,000 10,310 Variable 3.196% 12/17/2033 Nara Statutory Trust VI 03/22/2007 8,000 8,248 Variable 1.900% 06/15/2037 Center Capital Trust I 12/30/2003 18,000 14,457 Variable 3.125% 01/07/2034 Wilshire Statutory Trust II 03/17/2005 20,000 15,968 Variable 2.036% 03/17/2035 Wilshire Statutory Trust III 09/15/2005 15,000 11,325 Variable 1.650% 09/15/2035 Wilshire Statutory Trust IV 07/10/2007 25,000 18,332 Variable 1.630% 09/15/2037 Saehan Capital Trust I 03/30/2007 20,000 15,228 Variable 1.840% 06/30/2037 Total $ 126,000 $ 104,178 The carrying value of Debentures at December 31, 2020 and 2019 was $104.2 million and $103.0 million, respectively. At December 31, 2020 and 2019, acquired Debentures had remaining discounts of $25.7 million and $26.9 million, respectively. The carrying balance of Debentures is net of remaining discounts and includes common trust securities. The Company’s investment in the common trust securities of the issuer trusts was $3.9 million at both December 31, 2020 and 2019, and is included in other assets. Although the subordinated debt issued by the trusts are not included as a component of stockholders’ equity in the consolidated statements of financial condition, the debt is treated as capital for regulatory purposes. The Company’s trust preferred security debt issuances (less common trust securities) are includable in Tier 1 capital up to a maximum of 25% of capital on an aggregate basis as they were grandfathered in under BASEL III. Any amount that exceeds 25% qualifies as Tier 2 capital. Convertible Notes In 2018, the Company issued $217.5 million aggregate principal amount of 2.00% convertible senior notes maturing on May 15, 2038 in a private offering to qualified institutional buyers under Rule 144A of the Securities Act of 1933. The convertible notes can be converted into shares of the Company’s common stock at an initial rate of 45.0760 shares per $1,000 principal amount of the notes (equivalent to an initial conversion price of approximately $22.18 per share of common stock which represents a premium of 22.50% to the closing stock price on the date of the pricing of the notes). Holders of the convertible notes have the option to convert all or a portion of the notes at any time on or after February 15, 2023. Prior to February 15, 2023, the convertible notes cannot be converted except under certain specified scenarios. The Company can call the convertible notes, in part or in whole, on or after May 20, 2023 for 100% of the principal amount in cash. Holders of the convertible notes also have the option to put the convertible notes back to the Company on May 15, 2023, May 15, 2028, or May 15, 2033 for 100% of the principal amount in cash. The convertible notes can be settled in cash, stock, or a combination of stock and cash at the option of the Company. In accordance with accounting principles, the convertible notes issued by the Company were separated into a debt component and an equity component which represents the stock conversion option. The present value of the convertible notes was calculated based on a discount rate of 4.25%, which represented the current offering rate for similar types of debt without conversion options. The effective life of the convertible notes was estimated to be 5 years based on the first call and put date. The difference between the principal amount of the convertible notes and the present value was recorded as the convertible note discount and additional paid-in capital. The issuance costs related to the offering were also allocated into a debt component to be capitalized, and an equity component in the same percentage allocation of debt and equity of the convertible notes. The value of the convertible notes at issuance and carrying value as of December 31, 2020 and 2019 is presented in the tables below: As of December 31, 2020 Amortization/ Gross Accumulated Carrying Amount (Dollars in thousands) Convertible notes principal balance $ 217,500 $ — $ 217,500 Discount 5 years (21,880) 10,951 (10,929) Issuance costs to be capitalized 5 years (4,119) 2,113 (2,006) Carrying balance of convertible notes $ 191,501 $ 13,064 $ 204,565 As of December 31, 2019 Amortization/ Gross Accumulated Carrying Amount (Dollars in thousands) Convertible notes principal balance $ 217,500 $ — $ 217,500 Discount 5 years (21,880) 6,659 (15,221) Issuance costs to be capitalized 5 years (4,119) 1,298 (2,821) Carrying balance of convertible notes $ 191,501 $ 7,957 $ 199,458 Interest expense on the convertible notes for the twelve months ended December 31, 2020 and 2019 totaled $9.5 million and $9.3 million, respectively. Interest expense for the convertible notes includes accrued interest on the convertible note coupon, non-cash interest expense representing the conversion option or note discount, and interest expense from capitalized issuance costs. Non-cash interest expense and issuance cost capitalization expense will only be recorded for the first five

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In assessing the realization of deferred tax assets, management evaluates both positive and negative evidence, including the existence of any cumulative losses in the current year and the prior two years, the amount of taxes paid in available carry-back years, the forecasts of future income, applicable tax planning strategies, and assessments of current and future economic and business conditions. This analysis is updated quarterly and adjusted as necessary. Based on the analysis, the Company has determined that a valuation allowance for deferred tax assets was not required as of December 31, 2020 and 2019. A summary of the Company’s net operating loss carry-forwards is as follows: Federal State Remaining Expires Annual Remaining Expires Annual (Dollars in thousands) 2020 Saehan Bank (acquired by Wilshire) $ 2,261 2030 $ 226 $ 2,488 2033 $ — Pacific International Bank 4,829 2032 420 — N/A — Total $ 7,090 $ 646 $ 2,488 $ — 2019 Saehan Bank (acquired by Wilshire) $ 2,488 2030 $ 226 $ 2,488 2030 $ 226 Pacific International Bank 5,249 2032 420 — N/A — Total $ 7,737 $ 646 $ 2,488 $ 226 On June 29, 2020, California Assembly Bill 85 (A.B. 85) was signed into law. A.B. 85 suspends the use of the net operating loss (“NOL”) for the 2020, 2021, and 2022 tax years. For NOL incurred in tax years before 2020 for which a deduction is denied, the carryover period is extended by three years. The Company and its subsidiaries are subject to U.S. federal income tax as well as income tax of the state of California and various other states. The statute of limitations for the assessment of taxes for the consolidated Federal income tax return is closed for all tax years up to and including 2016. The expiration of the statute of limitations for the assessment of taxes for the various state income and franchise tax returns for the Company and subsidiaries varies by state. During the year ended December 31, 2020, New York State Department of Taxation concluded the examinations for the 2016, 2017 and 2018 tax years and State of Ohio Department of Taxation concluded the examination for the 2015 through 2019 tax years with no material adjustments. The Company is currently under examination by the New York City Department of Finance for the 2016, 2017 and 2018 tax years. While the outcome of the examination is unknown, the Company expects no material adjustments. A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2020 and 2019 is as follows: Year Ended December 31, 2020 2019 (Dollars in thousands) Balance at January 1, $ 141 $ 2,314 Additions based on tax positions related to prior years 2,716 — Reduction based on tax positions related to prior years (23) — Settlements with taxing authorities (84) (2,173) Balance at December 31, $ 2,750 $ 141 The total amount of unrecognized tax benefits was $2.8 million at December 31, 2020 and $141 thousand at December 31, 2019. The total amount of tax benefits that, if recognized, would favorably impact the effective tax rate by $2.4 million and $136 thousand at December 31, 2020 and 2019, respectively. The Company expects the total amount of unrecognized tax benefits to decrease by $902 thousand within the next twelve months due to an anticipated settlement with a state tax authority. The Company recognizes interest and penalties related to income tax matters in income tax expense. The Company had approximately $276 thousand and $34 thousand accrued for interest expense at December 31, 2020 and 2019, respectively and no amount accrued for penalties.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION In 2019, the Company’s stockholders approved the 2019 stock-based incentive plan (the “2019 Plan”) which provides for grants of stock options, SARs, restricted stock, performance shares, and performance units to non-employee directors, employees, and potentially consultants of the Company. Stock options may be either incentive stock options (“ISOs”), as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), or nonqualified stock options (“NQSOs”). The 2019 Plan replaced the 2016 Plan and stipulates that no further awards shall be made under prior plans. Therefore, awards are now only issued from the 2019 Plan. The 2019 Plan provides the Company flexibility to (i) attract and retain qualified non-employee directors, executives, other key employees, and consultants with appropriate equity-based awards to; (ii) motivate high levels of performance; (iii) recognize employee contributions to the Company’s success; and (iv) align the interests of the participants with those of the Company’s stockholders. The 2019 Plan initially had 4,400,000 shares that were available for grant to participants. The exercise price for shares under an ISO may not be less than 100% of fair market value on the date the award is granted under the Code. Similarly, under the terms of the plans, the exercise price for SARs and NQSOs may not be less than 100% of fair market value on the date of grant. Performance units are awarded to participants at the market price of the Company’s common stock on the date of award (after the lapse of the restriction period and the attainment of the performance criteria). All options not exercised generally expire 10 years after the date of grant. Outstanding ISOs, SARs, and NQSOs have vesting periods of three Under the 2019 Plan, 921,709 shares were available for future grants as of December 31, 2020. With the exception of the shares underlying stock options and restricted stock awards, the Board of Directors may choose to settle the awards by paying the equivalent cash value or by delivering the appropriate number of shares. The following is a summary of stock option activity for the year ended December 31, 2020: Number of Weighted- Weighted- Aggregate Outstanding - January 1, 2020 935,211 $ 15.34 Granted — — Exercised — — Expired (75,631) 16.16 Forfeited (8,000) 17.18 Outstanding - December 31, 2020 851,580 $ 15.25 4.43 $ 619 Options exercisable - December 31, 2020 813,580 $ 15.16 4.37 $ 619 The following is a summary of restricted and performance unit activity for the year ended December 31, 2020: Number of Weighted- Outstanding - January 1, 2020 1,035,744 $ 14.08 Granted 1,177,702 9.16 Vested (346,260) 14.91 Forfeited (148,464) 11.84 Outstanding - December 31, 2020 1,718,722 $ 10.73 The total fair value of restricted and performance units vested for the years ended December 31, 2020, 2019, and 2018 was $3.3 million, $1.6 million, and $2.7 million, respectively. The amount charged against income related to stock based payment arrangements was $8.1 million, $5.3 million, and $3.7 million for the years ended December 31, 2020, 2019 and 2018, respectively. At December 31, 2020, unrecognized compensation expense related to non-vested stock option grants and restricted and performance units totaled $15.4 million and is expected to be recognized over a remaining weighted average vesting period of 1.6 years. The estimated annual stock-based compensation expense as of December 31, 2020 for each of the succeeding years is indicated in the table below: Stock Based (Dollars in thousands) For the year ended December 31: 2021 $ 8,121 2022 5,087 2023 1,773 2024 348 2025 60 Total $ 15,389 The Company maintains the Hope Employee Stock Purchase Plan (“ESPP”) which allows eligible employees to purchase the Company’s common shares through payroll deductions made between the offering date and the purchase date. At the purchase date, the Company uses the accumulated funds to purchase shares of the Company’s common stock on behalf of the participating employees at a 10% discount to the closing price of the Company’s common shares. The closing price is the lower of either the closing price on the first day of the offering period or on the closing price on the purchase date. The dollar amount of common shares purchased under the ESPP must not exceed 20% of the participating employee’s base salary, subject to a cap of $25 thousand in stock value based on the grant date. The ESPP is considered compensatory under GAAP and compensation expense for the ESPP is recognized as part of the Company’s stock based compensation expense. The compensation expense for ESPP for the years ended December 31, 2020, 2019 and 2018 was $250 thousand, $217 thousand, and $319 thousand, respectively.

Employee Benefit Plans

Employee Benefit Plans	12 Months Ended

Retirement Benefits [Abstract]
Employee Benefit Plans	EMPLOYEE BENEFIT PLANS Deferred Compensation Plan - The Company established a deferred compensation plan that permits eligible officers, key executives, and directors to defer a portion of their compensation. The deferred compensation plan is still in effect and was amended in 2007 to be in compliance with the new IRC §409(A) regulations. The deferred compensation, together with accrued accumulated interest, is distributable in cash after retirement or termination of service. The deferred compensation liabilities at December 31, 2020 and 2019 amounted to $686 thousand and $765 thousand, respectively, and were included in other liabilities in the Consolidated Statements of Financial Condition. Interest expense recognized under the deferred compensation plan totaled $9 thousand, $34 thousand, and $22 thousand for 2020, 2019, and 2018, respectively. The Company established and the Board approved a Long Term Incentive Plan (“LTIP”) that rewards certain executive officers with deferred compensation if the Company meets certain performance goals, the NEOs meet individual performance goals, and the NEOs remain employed for a pre-determined period (between five 401(k) Savings Plan - The Company established a 401(k) savings plan, which is open to all eligible employees who are 21 years old or over and have completed three months of service. The Company matches 75% of the first 8% of the employee’s compensation contributed. Employer matching is vested 25% after 2 years of service, 50% after 3 years of service, 75% after 4 years of service, and 100% after 5 or more years of service. Total employer contributions to the plan amounted to approximately $5.4 million, $4.2 million, and $5.2 million for 2020, 2019 and 2018, respectively. Post-Retirement Benefit Plans - The Company has purchased life insurance policies and entered into split dollar life insurance agreements with certain directors and officers. Under the terms of the split dollar life insurance agreements, a portion of the death benefits received by the Company will be paid to beneficiaries named by the directors and officers. Total death benefits received by the Company was $1.0 million, $1.8 million, and $0, for 2020, 2019, and 2018, respectively. In 2016, the Company assumed Wilshire Bank’s Survivor Income Plans which was originally adopted in 2003 and 2005 for the benefit of the directors and officers in order to encourage their continued employment and service, and to reward them for their past contributions. Wilshire Bank had also entered into separate Survivor Income Agreements with officers and directors relating to the Survivor Income Plan. Under the terms of the Survivor Income Plan, each participant is entitled to a base amount of death proceeds as set forth in the participant’s election to participate, which base amount increases three percent per calendar year, but only until normal retirement age, which is 65. If the participant remains employed after age 65, the death benefit will be fixed at the amount determined at age 65. If a participant has attained age 65 prior to becoming a participant in the Survivor Income Plan, the death benefit shall be equal to the base amount set forth in their election to participate with no increases. The Company is obligated to pay any death benefit owed under the Survivor Income Plan in a lump sum within 90 days following the participant’s death. In 2011, the Company assumed Center Bank’s Survivor Income Plan which was adopted in 2004 for the benefit of the directors and officers of the bank in order to encourage their continued employment and service, and to reward them for their past contributions. Under the terms of the Survivor Income Plan, each participant is entitled to a base amount of death proceeds as set forth in the participant’s election to participate. The Company is obligated to pay any death benefit owed under the Survivor Income Plan in a lump sum within 90 days following the participant’s death. The participant’s rights under the Survivor Income Plans terminate upon termination of employment. Upon termination of employment (except for termination for cause), if the participant has achieved the vesting requirements outlined in the plan, the participant will have the option to convert the amount of death benefits calculated at such termination to a split dollar arrangement, provided such arrangement is available under bank regulations and/or tax laws. If available, the Company and the participant will enter into a split dollar agreement and a split dollar policy endorsement. Under such an arrangement, the Company would annually impute income to the officer or the director based on tax laws or rules in force upon conversion. The Company’s accumulated post-retirement benefit obligation at December 31, 2020, 2019, and 2018 was $9.0 million, $7.9 million, and $6.9 million, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Legal Contingencies In the normal course of business, the Company is involved in various legal claims. The Company has reviewed all legal claims against the Company with counsel for the year ended December 31, 2020 and has taken into consideration the views of such counsel as to the potential outcome of the claims. Loss contingencies for all legal claims totaled $1.3 million and $440 thousand at December 31, 2020 and 2019, respectively. It is reasonably possible the Company may incur losses in addition to the amounts the Company has accrued. However, at this time, the Company is unable to estimate the range of additional losses that are reasonably possible because of a number of factors, including the fact that certain of these litigation matters are still in their early stages and involve claims that the Company believes have little to no merit. The Company has considered these and other possible loss contingencies and does not expect the amounts to be material to the consolidated financial statements. Unfunded Commitments and Letters of Credit In the normal course of business, the Company is a party to financial instruments with off-balance sheet risk that are used to meet the financing needs of customers. These financial instruments include commitments to extend credit, standby letters of credit, commercial letters of credit, and commitments to fund investments in affordable housing partnerships. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Statements of Financial Condition. The Company’s exposure to credit loss in the event of nonperformance on commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as the Company does for extending loan facilities to customers. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon extension of credit, is based on the Company’s credit evaluation of the counterparty. The types of collateral that the Company may hold can vary and may include accounts receivable, inventory, property, plant and equipment, and income-producing properties. Commitments at December 31, 2020 and 2019 are summarized as follows: At December 31, 2020 2019 (Dollars in thousands) Commitments to extend credit $ 2,137,178 $ 1,864,947 Standby letters of credit 108,834 113,720 Other letters of credit 40,508 37,627 Commitments to fund investments in affordable housing partnerships 15,148 28,480 Commitments and letters of credit generally have variable rates that are tied to the prime rate. The amount of fixed rate commitments is not considered material to this presentation. From time to time, the Company enters into certain types of contracts that contingently require the Company to indemnify parties against third party claims and other obligations customarily indemnified in the ordinary course of the Company’s business. The terms of such obligations vary, and, generally, a maximum obligation is not explicitly stated. Therefore, the overall maximum amount of the obligations cannot be reasonably estimated. The most significant of these contracts relate to certain agreements with the Company’s officers and directors under which the Company may be required to indemnify such persons for liabilities arising out of their employment relationship. Historically, the Company has not been obligated to make significant payments for these obligations, and no liabilities have been recorded for these obligations in its consolidated statements of financial condition as of December 31, 2020 and 2019. The Company maintains an ACL for its off-balance sheet loan commitments which is calculated by loan type using estimated line utilization rates based on historical usage. Loss rates for outstanding loans is applied to the estimated utilization rates to calculate the ACL for off-balance sheet loan commitments. At December 31, 2020 and 2019, ACL for off-balance sheet loan commitments totaled $1.3 million and $636 thousand, respectively.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date reflecting assumptions that a market participant would use when pricing an asset or liability. There are three levels of inputs that may be used to measure fair value. The fair value inputs of the instruments are classified and disclosed in one of the following categories pursuant to ASC 820: Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. The quoted price shall not be adjusted for any blockage factor (i.e., size of the position relative to trading volume). Level 2 - Pricing inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Fair value is determined through the use of models or other valuation methodologies, including the use of pricing matrices. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 3 - Pricing inputs are unobservable for the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. The inputs into the determination of fair value require significant management judgment or estimation. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The Company uses the following methods and assumptions in estimating fair value disclosures for financial instruments. Financial assets and liabilities recorded at fair value on a recurring and non-recurring basis are listed as follows: Securities Available for Sale The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The fair values of the Company’s Level 3 securities available for sale were measured using an income approach valuation technique. The primary inputs and assumptions used in the fair value measurement were derived from the securities’ underlying collateral which included discount rates, prepayment speeds, payment delays, and an assessment of the risk of default of the underlying collateral, among other factors. Significant increases or decreases in any of the inputs or assumptions could result in a significant increase or decrease in the fair value measurement. Equity Investments With Readily Determinable Fair Value The fair value of the Company’s equity investments with readily determinable fair value is comprised of mutual funds. The fair value for these investments is obtained from unadjusted quoted prices in active markets on the date of measurement and is therefore classified as Level 1. Interest Rate Swaps The Company offers interest rate swaps to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The fair value of these derivatives is based on a discounted cash flow approach. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of interest rate swaps is classified as Level 2. Mortgage Banking Derivatives Mortgage banking derivative instruments consist of interest rate lock commitments and forward sale contracts that trade in liquid markets. The fair value is based on the prices available from third party investors. Due to the observable nature of the inputs used in deriving the fair value, the valuation of mortgage banking derivatives are classified as Level 2. Other Derivatives Other derivatives consist of interest rate swaps designated as cash flow hedges and risk participation agreements. The fair values of these other derivative financial instruments are based upon the estimated amount the Company would receive or pay to terminate the instruments, taking into account current interest rates and, when appropriate, the current credit worthiness of the counterparties. Interest rate swaps designated as cash flow hedges are classified within Level 2. Credit derivatives such as risk participation agreements are valued based on credit worthiness of the underlying borrower which is a significant unobservable input and therefore is classified as Level 3. Collateral Dependent Loans The fair values of collateral dependent loans are generally measured for ACL using the practical expedients permitted by ASC 326-20-35-5 including collateral dependent loans measured at an observable market price (if available), or at the fair value of the loan’s collateral (if the loan is collateral dependent). Fair value of the loan’s collateral, when the loan is dependent on collateral, is determined by appraisals or independent valuation, less costs to sell of 8.5%. Appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and income approach. Adjustment may be made in the appraisal process by the independent appraiser to adjust for differences between the comparable sales and income data available for similar loans and the underlying collateral. For commercial and industrial and asset backed loans, independent valuations may include a 20-60% discount for eligible accounts receivable and a 50-70% discount for inventory. These result in a Level 3 classification. OREO OREO is fair valued at the time the loan is foreclosed upon and the asset is transferred to OREO. The value is based primarily on third party appraisals, less costs to sell of up to 8.5% and result in a Level 3 classification of the inputs for determining fair value. OREO is reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted to lower of cost or market accordingly, based on the same factors identified above. Loans Held for Sale Loans held for sale are carried at the lower of cost or fair value, as determined by outstanding commitments from investors, or based on recent comparable sales (Level 2 inputs), if available, and if not available, are based on discounted cash flows using current market rates applied to the estimated life and credit risk (Level 3 inputs) or may be assessed based upon the fair value of the collateral which is obtained from recent real estate appraisals (Level 3 inputs). These appraisals may utilize a single valuation approach or a combination of approaches including the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in Level 3 classification of the inputs for determining fair value.

Although the exit price notion represents the value that would be received to sell an asset or paid to transfer a liability, the actual price received for a sale of assets or paid to transfer liabilities could be different from exit price disclosed. The methods and assumptions used to estimate fair value are described as follows: The carrying amount is the estimated fair value for cash and cash equivalents, savings and other interest bearing demand deposits, equity investments without readily determinable fair values, customer’s and Bank’s liabilities on acceptances, noninterest bearing deposits, short-term debt, secured borrowings and variable rate loans or deposits that reprice frequently and fully. For loans the fair value is determined through a discounted cash flow analysis which incorporates probability of default and loss given default rates on an individual loan basis. The discount rate is based on the LIBOR Swap Rate for fixed rate loans, while variable loans start with the corresponding index rate and an adjustment was made on certain loans which considered factors such as servicing costs, capital charges, duration, asset type incremental costs, and use of projected cash flows. Residential real estate loans fair values included Fannie Mae and Freddie Mac prepayment speed assumptions or a third party index based on historical prepayment speeds. Fair value of time deposits is based discounted cash flow analysis using recent issuance rates over the prior three months and a market rate analysis of recent offering rates for retail products. Wholesale time deposits fair values incorporated brokered time deposit offering rates. The fair value of the Company’s subordinated debentures is based on current rates for similar financing. Fair value for the Company’s convertible notes is based on the actual last traded price of the notes. The fair value of commitments to fund loans represents fees currently charged to enter into similar agreements with similar remaining maturities and is not presented herein. The fair value of these financial instruments is not material to the consolidated financial statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS The Company offers a loan hedging program to certain loan customers. Through this program, the Company originates a variable rate loan with the customer. The Company and the customer will then enter into a fixed interest rate swap. Lastly, an identical offsetting swap is entered into by the Company with a correspondent bank. These “back-to-back” swap arrangements are intended to offset each other and allow the Company to book a variable rate loan, while providing the customer with a contract for fixed interest payments. In these arrangements, the Company’s net cash flow is equal to the interest income received from the variable rate loan originated with the customer. These customer swaps are not designated as hedging instruments and are recorded at fair value in other assets and other liabilities. The changes in fair value is recognized in the income statement in other income and fees. The Company is required to hold cash as collateral for the swaps, which is recorded in other assets on the consolidated statement of financial condition. Total cash held as collateral for back to back swaps was $9.1 million at December 31, 2020 and $8.9 million at December 31, 2019. At December 31, 2020 and 2019, interest rate swaps related to the Company’s loan hedging program that were outstanding is presented in the following table: December 31, 2020 December 31, 2019 (Dollars in thousands) Interest rate swaps on loans with correspondent banks Notional amount $ — $ 137,890 Weighted average remaining term (years) 0.0 7.2 Pay fixed rate (weighted average) — % 3.62 % Received variable rate (weighted average) — % 3.83 % Estimated fair value $ — $ 739 Interest rate swaps on loans with correspondent banks Notional amount $ 503,929 $ 282,326 Weighted average remaining term (years) 6.8 6.9 Pay fixed rate (weighted average) 3.86 % 4.48 % Received variable rate (weighted average) 2.26 % 3.98 % Estimated fair value $ (34,606) $ (9,614) Back to back interest rate swaps with loan customers Notional amount $ — $ 137,890 Weighted average remaining term (years) 0.0 7.2 Received fixed rate (weighted average) — % 3.62 % Pay variable rate (weighted average) — % 3.83 % Estimated fair value $ — $ (739) Back to back interest rate swaps with loan customers Notional amount $ 503,929 $ 282,326 Weighted average remaining term (years) 6.8 6.9 Received fixed rate (weighted average) 3.86 % 4.48 % Pay variable rate (weighted average) 2.26 % 3.98 % Estimated fair value $ 34,606 $ 9,614 At December 31, 2020, the Company had risk participation agreements with an outside counterparty for an interest rate swap related to loans in which it is a participant. The risk participation agreements provide credit protection to the financial institution should the borrower fail to perform on their interest rate derivative contract. Risk participation agreements are credit derivatives not designated as hedges. Credit derivatives are not speculative and are not used to manage interest rate risk in assets or liabilities. Changes in the fair value in credit derivatives are recognized directly in earnings. The fee received, less the estimate of the loss for credit exposure, was recognized in earnings at the time of the transaction. At December 31, 2020, the notional amount of the risk participation agreements sold was $112.8 million with a credit valuation adjustment of $398 thousand. As part of the overall liability management, the Company utilizes interest rate swap agreements to help manage interest rate risk positions. The notional amount of the interest rate swaps do not represent the amount exchanged by the parties. The exchange of cash flows is determined by reference to the notional amounts and the other terms of the interest rate swap agreements. The Company had one existing interest rate swap agreement as of December 31, 2020 with a notional amount of $100.0 million designated as cash flow hedges of certain LIBOR-based debt. The swap was entered into during 2020 and was determined to be fully effective during the period presented. The aggregate fair value of the swap is recorded in derivative liabilities with changes in fair value recorded in other comprehensive income. The gain or loss on the derivative is recorded in accumulated other comprehensive income (“AOCI”) and is subsequently reclassified into interest expense and interest income in the period during which the hedged forecasted transaction affects earnings. Amounts reported in AOCI related to interest rate swap derivatives will be reclassified to interest income and interest expense as interest payments are received or paid on the Company’s derivatives. The Company expects the hedge to remain fully effective during the remaining term of the swap. For the twelve months ended December 31, 2020, the Company reclassified $52 thousand from accumulated other comprehensive income to interest expense. There were no reclassification from accumulated comprehensive income to interest expense during twelve months ended December 31, 2019 as there was no outstanding interest rate swap designated as cash flow hedges. Total cash held as collateral for interest rate swaps was $54.9 million at December 31, 2020 and $22.1 million at December 31, 2019. December 31, 2020 December 31, 2019 (Dollars in thousands) Interest rate swaps designated as cash flow hedge (included in other liabilities) Notional amount $ 100,000 $ — Weighted average remaining term (years) 4.3 0.0 Received variable rate (weighted average) 0.22 % — % Pay fixed rate (weighted average) 0.49 % — % Estimated fair value $ (602) $ — The Company enters into various stand-alone mortgage-banking derivatives in order to hedge the risk associated with the fluctuation of interest rates. Changes in fair value are recorded as mortgage banking revenue. Residential mortgage loans funded with interest rate lock commitments and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. At December 31, 2020 and 2019, the Company had approximately $43.8 million and $10.5 million, respectively, in interest rate lock commitments, all of which was entered into forward sales commitments for the future delivery of residential mortgage loans.

Equity [Abstract]
Stockholders' Equity	STOCKHOLDERS’ EQUITY Total stockholders’ equity at December 31, 2020 was $2.05 billion, compared to $2.04 billion at December 31, 2019. The increase in stockholders’ equity was due to the increase from income earned during the year and an increase in accumulated other comprehensive income partially offset by an increase in treasury stock from shares repurchased during 2020. In June 2019, the Company’s Board of Directors approved another share repurchase program that authorizes the Company to repurchase up to $50.0 million of its common stock. During the year ended December 31, 2019, the Company repurchased 943,094 shares of common stock totaling $13.8 million. The repurchased shares were recorded as treasury stock and reduced the total number of common shares outstanding. In 2020, the Company completed the $50.0 million repurchase plan though the repurchase of 2,716,034 shares of common stock totaling $36.2 million. As of December 31, 2020, the Company had repurchased a total of 12,661,581 shares of its common stock totaling $200.0 million as part of all previous repurchase programs that were authorized by the Company’s Board of Directors. Dividends The Company’s Board of Directors approved and the Company paid quarterly dividends of $0.14 per common share in each quarter of 2020 and 2019. The Company paid aggregate dividends of $69.2 million and $70.9 million to common stockholders in 2020 and 2019, respectively. Accumulated Other Comprehensive Income (Loss) The following table presents the changes to accumulated other comprehensive income (loss) for the years ended December 31, 2020, 2019, and 2018: December 31, 2020 December 31, 2019 December 31, 2018 (Dollars in thousands) Balance at beginning of period $ 9,149 $ (32,705) $ (21,781) Unrealized gains (losses) on securities available for sale 41,562 59,851 (16,201) Unrealized (losses) on interest rate swaps for cash flow hedge (602) — — Reclassification adjustments for net gains realized in income (7,583) (282) — Tax effect (9,773) (17,715) 4,996 Total other comprehensive income (loss) 23,604 41,854 (11,205) Reclassification to retained earnings per ASU 2016-01 — — 281 Balance at end of period $ 32,753 $ 9,149 $ (32,705) For the twelve months ended December 31, 2020, $7.6 million, was reclassified out of accumulated other comprehensive income to reflect the gain on sale of securities. For the twelve months ended December 31, 2019 and 2018, $282 thousand and $0, respectively, was reclassified out of accumulated other comprehensive loss to reflect the gain on sale and calls of securities. In 2018, the Company adopted ASU 2016-01 “Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” As a result of the adoption of ASU 2016-01, the Company no longer accounts for mutual funds as securities available for sale and accounts for these investments as equity investments with changes to fair value recorded through earnings. In accordance with ASU 2016-01, the Company reclassified $281 thousand in net unrealized losses included in other comprehensive income, net of taxes to retained earnings on January 1, 2018.

Regulatory Assets and Liabilities Disclosure [Abstract]
Regulatory Matters	REGULATORY MATTERS The Company and the Bank are subject to various regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a material and adverse effect on the Company’s and the Bank’s business, financial condition and results of operation, such as restrictions on growth or the payment of dividends or other capital distributions or management fees. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk-weightings and other factors. In July 2013, the federal bank regulatory agencies adopted final regulations, which revised their risk-based and leverage capital requirements for banking organizations to meet requirements of the Dodd-Frank Act and to implement the Basel III international agreements reached by the Basel Committee. The final rules began for the Company and the Bank on January 1, 2015 and were subject to a phase-in period through January 1, 2019. The final rules that had an impact on the Company and the Bank include: • An increase in the minimum Tier 1 capital ratio from 4.00% to 6.00% of risk-weighted assets; • A new category and a required 4.50% of risk-weighted assets ratio was established for “Common Equity Tier 1” as a subset of Tier 1 capital limited to common equity; • A minimum non-risk-based leverage ratio was set at 4.00%, eliminating a 3.00% exception for higher rated banks; • Changes in the permitted composition of Tier 1 capital to exclude trust preferred securities, mortgage servicing rights and certain deferred tax assets and include unrealized gains and losses on available for sale debt and equity securities; • The risk-weights of certain assets for purposes of calculating the risk-based capital ratios are changed for high volatility commercial real estate acquisition, development and construction loans, certain past due non-residential mortgage loans and certain mortgage-backed and other securities exposures; and • A new additional capital conservation buffer of 2.50% of risk-weighted assets over each of the required capital ratios was added and must be met to avoid limitations on the ability of the B ank to pay dividends, repurchase shares, or pay discretionary bonuses. The capital conservation buffer was initially 0.625% in 2016 and was fully phased-in at 2.50% as of January 1, 2019. As of December 31, 2020, the ratios for the Company and the Bank were sufficient to meet the fully phased-in conservation buffer. As of December 31, 2020 and 2019, the most recent regulatory notification categorized the Bank as “well-capitalized” under the regulatory framework for prompt corrective action. To generally be categorized as “well-capitalized”, the Bank must maintain minimum total risk-based, Tier 1 risk-based, common equity Tier 1, and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since the most recent notification from regulators that management believes has changed the institution’s category.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	REVENUE RECOGNITION With the adoption of ASU 2014-09 (Topic 606), the Company recognizes revenue when obligations under the terms of a contract with customers are satisfied. Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also out of scope of the new guidance. Topic 606 is applicable to noninterest revenue streams such as deposit related fees, wire transfer fees, and certain OREO related net gains or expenses. However, the recognition of these revenue streams for the Company did not change significantly upon adoption of Topic 606. Noninterest revenue streams within the scope of Topic 606 are discussed below. Service Charges on Deposit Accounts and Wire Transfer Fees Service charges on noninterest and interest bearing deposit accounts consist of monthly service charges, customer analysis charges, non-sufficient funds (“NSF”) charges, and other deposit account related charges. The Company’s performance obligation for account analysis charges and monthly service charges is generally satisfied, and the related revenue is recognized over the period in which the service is provided. NSF charges, other deposit account related charges, and wire transfer fees are transaction based, and therefore the Company’s performance obligation is satisfied at the point of the transaction, and related revenue recognized at that point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. Service charges on deposit accounts and wire transfers are summarized below: For the Year Ended December 31, 2020 2019 (Dollars in thousands) Noninterest bearing deposit account income: Monthly service charges $ 1,301 $ 1,608 Customer analysis charges 6,765 7,801 NSF charges 3,687 7,654 Other service charges 598 799 Total noninterest bearing deposit account income 12,351 17,862 Interest bearing deposit account income: Monthly service charges 92 71 Total service fees on deposit accounts $ 12,443 $ 17,933 Wire transfer fee income: Wire transfer fees $ 3,188 $ 4,058 Foreign exchange fees 389 500 Total wire transfer fees $ 3,577 $ 4,558 OREO are often sold in transactions that, under ASU 2014-09, may not be considered a contract with a customer because the sale of the asset may not be an output of the Company’s ordinary activities. However, sales of nonfinancial assets, including in-substance nonfinancial assets, should be accounted for in accordance with ASC 610-20, “ Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets”

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE (“EPS”) Basic EPS does not reflect the possibility of dilution that could result from the issuance of additional shares of common stock upon exercise or conversion of outstanding equity awards or convertible notes and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if stock options, convertible notes, or other contracts to issue common stock were exercised or converted to common stock that would then share in the Company’s earnings. For the years ended December 31, 2020 and 2019, stock options and restricted shares awards of approximately 827,405 and 894,226 shares of common stock, respectively, were excluded in computing diluted earnings per common share because they were anti-dilutive. In 2018, the Company issued $217.5 million in convertible senior notes maturing on May 15, 2038. The convertible notes can be converted into the Company’s shares of common stock at an initial rate of 45.0760 shares per $1,000 principal amount of the notes (See footnote 10 “Subordinated Debentures and Convertible Notes” for additional information regarding convertible notes issued). For the years ended December 31, 2020 and 2019, shares related to the convertible notes issued were not included in the Company’s diluted EPS calculation. In accordance with the terms of the convertible notes and settlement options available to the Company, no shares would have been delivered to investors of the convertible notes upon assumed conversion based on the Company’s common stock price during the years ended December 31, 2020 and 2019. In 2019, the Company’s Board of Directors approved a share repurchase program that authorized the Company to repurchase up to $50.0 million of its common stock. During the year ended December 31, 2019, the Company repurchased 943,094 shares of common stock totaling $13.8 million. During the year ended December 31, 2020, the Company repurchased 2,716,034 shares of common stock totaling $36.2 million. The repurchased shares were recorded as treasury stock and reduced the total number of common shares outstanding. During the year ended December 31, 2018, the Company repurchased 5,565,696 shares of common stock totaling $100.0 million. The following table shows the computation of basic and diluted EPS for the years ended December 31, 2020, 2019, and 2018: Net Income Weighted Average Earnings Per (Dollars in thousands, except share and per share data) 2020 Basic EPS - common stock $ 111,515 123,501,401 $ 0.90 Effect of dilutive securities: Stock options, restricted stock, performance awards, and ESPP shares 387,942 Diluted EPS - common stock $ 111,515 123,889,343 $ 0.90 2019 Basic EPS - common stock $ 171,040 126,598,564 $ 1.35 Effect of dilutive securities: Stock options, restricted stock, performance awards, and ESPP shares 276,756 Diluted EPS - common stock $ 171,040 126,875,320 $ 1.35 2018 Basic EPS - common stock $ 189,589 131,716,726 $ 1.44 Effect of dilutive securities: Stock options, restricted stock, and performance awards 237,466 Diluted EPS - common stock $ 189,589 131,954,192 $ 1.44

Servicing Assets

Servicing Assets	12 Months Ended

Transfers and Servicing [Abstract]
Servicing Assets	SERVICING ASSETS Servicing assets are recognized when SBA and residential mortgage loans are sold with the servicing retained by the Company and the related income is recorded as a component of gains on sales of loans. Servicing assets are initially recorded at fair value based on the present value of the contractually specified servicing fee, net of servicing costs, over the estimated life of the loan, using a discount rate. The Company’s servicing costs approximate the industry average of 40 basis points. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Management periodically evaluates servicing assets for impairment based upon the fair value of the rights as compared to the carrying amount. Impairment is determined by stratifying rights into groupings based on loan type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. As of December 31, 2020 and 2019, the Company did not have a valuation allowance on it servicing assets. The changes in net servicing assets for the years ended December 31, 2020 and 2019 were as follows: Year Ended December 31, 2020 2019 (Dollars in thousands) Balance at beginning of period $ 16,417 $ 23,132 Additions through originations of servicing assets 2,864 1,790 Amortization (6,589) (8,505) Balance at end of period $ 12,692 $ 16,417 Loans serviced for others are not reported as assets. The principal balances of loans serviced for other institutions were $1.23 billion and $1.35 billion as of December 31, 2020 and 2019. Total servicing assets at December 31, 2020 totaled $12.7 million and were comprised of $8.4 million in SBA servicing assets and $4.3 million in mortgage related servicing assets. At December 31, 2019, servicing assets totaled $16.4 million, comprised of $12.1 million in SBA servicing assets and $4.3 million in mortgage related servicing assets. The Company utilizes the discounted cash flow method to calculate the initial excess servicing assets. The inputs used in evaluating servicing assets for impairment at December 31, 2020 and 2019 are presented below. December 31, 2020 December 31, 2019 SBA Servicing Assets: Weighted-average discount rate 9.93% 9.19% Constant prepayment rate 14.40% 14.17% Mortgage Servicing Assets: Weighted-average discount rate 8.26% 9.25% Constant prepayment rate 8.63% 9.57%

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation— The accounting and reporting policies of the Company are in accordance with accounting principles generally accepted in the United States of America and conform to practices within the banking industry. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, principally the Bank. Intercompany transactions and balances are eliminated in consolidation.
Cash Flows	—Cash and cash equivalents include cash and due from banks, interest-earning deposits, and federal funds sold, which have original maturities less than 90 days. The Company may be required to maintain reserve and clearing balances with the Federal Reserve Bank under the Federal Reserve Act. The reserve and clearing requirement balance was $0 at December 31, 2020 and 2019. Net cash flows are reported for customer loan and deposit transactions, investment transactions, federal funds purchased, deferred income taxes, and other assets and liabilities.
Interest-Bearing Deposits in Other Financial Institutions and Other Investments	Interest-Bearing Deposits in Other Financial Institutions —Interest-bearing deposits in other financial institutions are comprised of the Company’s investments in certificates of deposits that have original maturities greater than 90 days.
Securities	Securities— Securities are classified and accounted for as follows: (i) Securities that the Company has the positive intent and ability to hold to maturity are classified as “held to maturity” and reported at amortized cost. At December 31, 2020 and 2019, the Company did not own securities in this category; (ii) Securities are classified as “available for sale” when they might be sold before maturity and are reported at fair value. Unrealized holding gains and losses are reported as a separate component of stockholders’ equity in accumulated other comprehensive income, net of taxes. Accreted discounts and amortized premiums on securities are included in interest income using the interest method, and realized gains or losses related to sales of securities recorded on trade date and are calculated using the specific identification method, without anticipating prepayments, except for mortgage-backed securities where prepayments are expected. On January 1, 2020, the Company adopted ASU 2016-13 and implemented the CECL methodology for allowance for credit losses on its investment securities available for sale. The new CECL methodology replaces the other-than-temporary impairment model that previously existed. The Company did not have a day 1 allowance impact attributable to its investment securities portfolio and did not have an allowance for credit losses as of December 31, 2020. The Company has elected to exclude accrued interest from the amortized cost of its investment securities available for sale. The Company evaluates securities in unrealized loss position for impairment related to credit losses on at least a quarterly basis. Securities in unrealized loss positions are first assessed as to whether the Company intend to sell, or if it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If one of the criteria is met, the security’s amortized cost basis is written down to fair value through current earnings. For securities that do not meet these criteria, the Company evaluates whether the decline in fair value resulted from credit losses or other factors. In evaluating whether a credit loss exists, the Company has set up an initial filter for impairment triggers. Once the quantitative filters have been triggered, the securities are placed on a watch list and an additional assessment is performed to identify whether a credit impairment exists. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security and the issuer, among other factors. If this assessment indicates that a credit loss exists, the Company compares the present value of cash flows expected to be collected from the security with the amortized cost basis. If the present value of cash flows expected to be collected is less than the amortized cost basis for the security, a credit loss exists and an allowance for credit losses is recorded, limited to the amount that the fair value of the security is less than its amortized cost basis. Unrealized losses that have not been recorded through an allowance for credit losses is recognized in other comprehensive income, net of applicable taxes. No allowance for credit losses for available for sale securities was recorded at December 31, 2020.
Equity Investments	Equity Investments —On January 1, 2018, the Company adopted ASU 2016-01 and reclassified its mutual funds, equity stock, correspondent bank stock, Community Development Financial Institutions Fund (“CDFI”) investments, and Community Reinvestment Act (“CRA”) investments as equity investments. The Company’s mutual funds are considered equity investments with readily determinable fair values and changes to fair value are recorded in other noninterest income. The Company sold all of its investment in equity stock in 2019. The Company’s investment in correspondent bank stock, CDFI investments, and CRA investments are equity investments without readily determinable fair values. Equity investments without readily determinable fair values are measured at cost, less impairment, and are adjusted for observable price changes which is recorded in noninterest income.
Derivative Financial Instruments and Hedging Transactions	Derivative Financial Instruments and Hedging Transactions —As part of the Company’s asset and liability management strategy, the Company uses derivative financial instruments, such as interest rate swaps, risk participation agreements, and caps and floors, with the overall goal of minimizing the impact of interest rate fluctuations on net interest margin. The Company’s interest rate swaps and caps involve the exchange of fixed rate and variable rate interest payment obligations without the exchange of the underlying notional amounts and are therefore accounted for as stand-alone derivatives. Derivative instruments are included in other assets or accrued expenses and other liabilities on the Consolidated Balance Sheet at fair value. At the inception of the derivative contract, the Company designates the derivative as (1) a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (2) an instrument with no hedging designation (“stand-alone derivative”). For a cash flow hedge, the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, in noninterest income. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. The related cash flows are recognized on the cash flows from operating activities section on the Consolidated Statement of Cash Flows. Residential mortgage loans funded with interest rate lock commitments and forward commitments for the future delivery of mortgage loans to third party investors, are both considered derivatives. The Company accounts for loan commitments related to the origination of mortgage loans that will be held-for-sale as derivatives at fair value on the balance sheet, with changes in fair value recorded in earnings in the period in which the changes occur. As part of the Company’s overall risk management, the Company’s Asset Liability Committee, which meets monthly, monitors and measures interest rate risk and the sensitivity of assets and liabilities to interest rate changes, including the impact of derivative transactions. The Company formally documents all relationships between derivatives and hedged items, as well as the risk-management objective and strategy for undertaking various hedge transactions. This documentation includes linking cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used in hedging transactions are highly effective in offsetting changes in cash flows of the hedged items. The Company discontinues hedge accounting prospectively when it is determined that (1) the derivative is no longer effective in offsetting changes in the cash flows of the hedged item (2) the derivative expires, is sold, or terminated (3) the derivative instrument is de-designated as a hedge because the forecasted transaction is no longer probable of occurring (4) a hedged firm commitment no longer meets the definition of a firm commitment (5) or management otherwise determines that designation of the derivative as a hedging instrument is no longer appropriate. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transaction is still expected to occur, changes in value that were accumulated in other comprehensive income are amortized or accreted into earnings over the same periods which the hedged transactions will affect earnings. Company enters into risk participation agreements with outside counterparties for interest rate swaps related to loans in which it is a participant. The risk participation agreements provide credit protection to the financial institution should the borrower fail to perform on its interest rate derivative contract. Risk participation agreements are credit derivatives not designated as hedges. Credit derivatives are not speculative and are not used to manage interest rate risk in assets or liabilities. Changes in the fair value in credit derivatives are recognized directly in earnings. The fee received, less the estimate of the loss for credit exposure, was recognized in earnings at the time of the transaction.
Loans Held for Sale and Loans	Loans Held for Sale —Residential mortgage loans that the Company has the intent to sell prior to maturity have been designated as held for sale at origination and are recorded at the lower of cost or fair value, on an aggregate basis. Certain loans which were originated with the intent to hold to maturity are subsequently transferred to held for sale once there is an intent to sell the loan. A valuation allowance is established if the aggregate fair value of such loans is lower than their cost and charged to earnings. Gains or losses recognized upon the sale of loans are determined on a specific identification basis. Loan transfers are accounted for as sales when control over the loan has been surrendered. Control over such loans is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Company does not maintain control over the transferred assets through an agreement to repurchase them before their maturity. Loans— Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the amount of unpaid principal, adjusted for net deferred fees and costs, premiums and discounts, purchase accounting fair value adjustments, and allowance for credit losses. Interest income is accrued on the unpaid principal balance. Nonrefundable loan origination fees and certain direct origination costs are deferred and recognized in interest income using the level-yield method over the life of the loan. Interest on loans is credited to income as earned and is accrued only if deemed collectible. The loan portfolio consists of four segments: real estate, commercial business, residential mortgage, and consumer and other loans. Real estate loans are extended for the purchase and refinance of commercial real estate and are generally secured by first deeds of trust and are collateralized by residential or commercial properties. Commercial business loans are loans provided to businesses for various purposes such as for working capital, purchasing inventory, debt refinancing, business acquisitions, international trade finance activities, and other business related financing needs and also include warehouse lines of credit, syndicated loans, and SBA Paycheck Protection Program (“PPP”) loans. Residential mortgage loans are extended for personal, family, or household use and are secured by a mortgage or deed of trust. Consumer and other loans consist of home equity, credit card, and other personal loans. On January 1, 2020, the Company adopted ASU 2016-13, or CECL, using the modified retrospective method for all of its loans measured at amortized cost. With the adoption of CECL, the Company reassessed its loan portfolio segments and classes of loans receivable and made changes based on the new allowance for credit losses methodology. As a result, the Company now discloses residential mortgage loans as a separate segment and class of receivable. Trade finance loans, which were previously disclosed as a distinct segment and class of receivable, are now combined with commercial business loans. Prior period balances have been reclassified to conform with the current presentation. Generally, loans are placed on nonaccrual status and the accrual of interest is discontinued if principal or interest payments become 90 days past due and/or management deems the collectability of the principal and/or interest to be in question. Loans to a customer whose financial condition has deteriorated are considered for nonaccrual status whether or not the loan is 90 days or more past due. Generally, payments received on nonaccrual loans are recorded as principal reductions. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Other loan fees and charges, representing service costs for the prepayment of loans, for delinquent payments, or for miscellaneous loan services, are recorded as income when collected. The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including, but not limited to, current financial information, historical payment experience, credit documentation, public information, and current economic trends. Homogeneous loans (i.e., home mortgage loans, home equity lines of credit, overdraft loans, express business loans, and automobile loans) are not risk rated and credit risk is analyzed largely by the number of days past due. This analysis is performed at least on a quarterly basis: • Pass: Loans that meet a preponderance or more of the Company’s underwriting criteria and that evidence an acceptable level of risk. • Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. • Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the borrower or by the collateral pledged, if any. Loans in this classification have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. • Doubtful/Loss: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or repayment in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Allowance for Credit Losses (“ACL”) —The Company calculates its ACL by estimating expected credit losses on a collective basis for loans that share similar risk characteristics. Loans that do not share similar risk characteristics with other loans are evaluated for credit losses on an individual basis. The Company uses a combination of a modeled and non-modeled approach that incorporates current and future economic conditions to estimate lifetime expected losses on a collective basis. The Company uses Probability of Default (“PD”), Loss Given Default (“LGD”), and Exposure at Default (“EAD”) methodologies with quantitative factors and qualitative considerations in calculation of the allowance for credit losses for collectively assessed loans. The Company uses a reasonable and supportable period of 2 years at which point loss assumptions revert back to historical loss information by means of 1 year reversion period. For a discussion of the Company’s former incurred loss allowance for loan losses methodology, please refer to the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The ACL for the Company’s construction, credit card, and certain consumer loans is calculated based on a non-modeled approach utilizing historical loss rates to estimate losses. A non-modeled approach was chosen for these loans as fewer data points exist which could result in high levels of estimated loss volatility under a modeled approach. Materiality was another factor in using a non-modeled approach for these loans as in aggregate, non-modeled loans represented approximately than 2% of the Company’s total loan portfolio as of December 31, 2020. With the adoption of CECL, the Company formed an Economic Forecast Committee (“EFC”) to review economic forecast scenarios that are incorporated in the Company’s ACL. The EFC reviews multiple scenarios put together by an independent third party and chooses a single scenario that best aligns with management’s expectation of future economic conditions. The forecast scenarios contain certain macroeconomic variables that are incorporated into the Company’s modeling process, including GDP, unemployment rates, interest rates, and commercial real estate prices. As of December 31, 2020, the Company chose a forecast scenario that incorporates the effect of the COVID-19 pandemic into estimates of future economic conditions. The allowance for credit losses at December 31, 2020 utilizes the Moody’s Baseline scenario, as well as more specific information, including updated CRE market data which reflects deterioration primarily in the hospitality industry. Additionally, in order to systematically quantify the credit risk impact of other trends and changes within the loan portfolio that may not be capture by the modeled and non-modeled approach, the Company utilizes qualitative adjustments to estimate total expected losses. The parameters for making adjustments are established under a Credit Risk Matrix that provides different possible scenarios for each of the factors below. The Credit Risk Matrix and the possible scenarios enable the Bank to qualitatively adjust the allowance for credit losses by as much as 25 basis points for each loan type pool. This matrix considers the following seven factors, which are patterned after the guidelines provided under the Federal Financial Institutions Examination Council (“FFIEC”) Interagency Policy Statement on the Allowance for Loan and Lease Losses, updated to reflect the application of the CECL methodology: • Changes in lending policies and procedures, including underwriting standards and collection, charge-off, and recovery practices; • Changes in the nature and volume of the loan portfolio; • Changes in the experience, ability and depth of lending management and staff; • Changes in the trends of the volume and severity of past due loans, Classified Loans, nonaccrual loans, troubled debt restructurings and other loan modifications; • Changes in the quality of the loan review system and the degree of oversight by the Directors; • The existence and effect of any concentrations of credit and changes in the level of such concentrations; and • The effect of other external factors, such as competition, legal and regulatory requirements, and others that have an impact on the level of estimated losses in the Company’s loan portfolio. For loans which do not share similar risk characteristics such as nonaccrual and TDR loans above $500 thousand, the Company evaluates these loans on an individual basis in accordance with ASC 326. These nonaccrual and TDR loans are considered to have different risk profiles than performing loans and therefore are evaluated separately. The Company collectively assesses TDRs and nonaccrual loans with balances below $500 thousand along with the performing and accrual loans in order to reduce the operational burden of individually assessing small TDR and nonaccrual loans with immaterial balances. For individually assessed loans, the ACL is measured using either 1) the present value of future cash flows discounted at the loan’s effective interest rate; 2) the loan’s observable market price; or 3) the fair value of the collateral, if the loan is collateral dependent. For the collateral dependent loans, the Company obtains a new appraisal to determine the fair value of underlying loan collateral. The appraisals are based on an “as-is” valuation. To ensure that appraised values remain current, the Company either obtains updated appraisals every twelve months from a qualified independent appraiser or an internal evaluation of the collateral is performed by qualified personnel. If the third party market data indicates that the value of the collateral property has declined since the most recent valuation date, management adjusts the value of the property downward to reflect current market conditions. If the fair value of the collateral is less than the amortized balance of the loan, the Company recognizes an ACL with a corresponding charge to the provision for credit losses. As of December 31, 2020, the Company recorded $1.0 million in ACL on its loan accrued interest receivable balances attributable to COVID-19 payment deferral modifications. The ACL was estimated by using the same loss ratios calculated for the underlying loans under the CECL allowance methodology and applying the ratios to the accrued interest portion of modified loans. Total accrued interest on the Consolidated Statement of Financial Condition is presented net of any ACL and changes to the accrued interest ACL is recorded in credit related expenses. TDR loans are individually evaluated in accordance with ASC 310 and ASC 326. The concessions may be granted in various forms, including reduction in the stated interest rate, reduction in the amount of principal amortization, forgiveness of a portion of a loan balance or accrued interest, or extension of the maturity date. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed on the probability that the borrower will be in payment default on their debt in the foreseeable future without the modification. This evaluation is performed under the Bank’s internal underwriting policy. TDR loans on accrual status are comprised of loans that were accruing at the time of restructuring and for which the Company anticipates full repayment of both principal and interest under the restructured terms. TDR loans that are on nonaccrual status can be returned to accrual status after a period of sustained performance, generally determined to be six months of timely payments as modified. Sustained performance includes the periods prior to the modification and if the prior performance met or exceeded the modified terms. The CARES Act provides banks the option to temporarily suspend certain requirements under U.S. GAAP related to TDR accounting for a limited period of time to account for the effects of COVID-19 if (i) the loan modification is made between March 1, 2020 and the earlier of January 1, 2022 or 60 days after the end of the coronavirus emergency declaration and (ii) the applicable loan was not more than 30 days past due as of December 31, 2019. As such, all modified loans that met the criteria outlined within Section 4013 of the CARES Act were not classified as TDR loans as of December 31, 2020, unless the loans were TDR prior to the COVID-19 modification.
OREO	OREO —OREO, which represents real estate acquired through foreclosure in satisfaction of commercial and real estate loans, is stated at fair value less estimated selling costs of the real estate. Loan balances in excess of the fair value of the real estate acquired at the date of acquisition are charged to the allowance for credit losses. Any subsequent operating expenses or income, reduction in estimated fair values, and gains or losses on disposition of such properties are charged or credited to current operations. For the year ended December 31, 2020, the Company foreclosed on properties with an aggregate carrying value of $2.9 million. The Company recorded $4.3 million in net valuation losses subsequent to the foreclosures during the year ended December 31, 2020, and the Company sold OREO properties for total proceeds of $2.5 million during the year.
FHLB Stock	FHLB Stock —The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Premises and Equipment	Premises and Equipment —Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization of premises and equipment are computed on the straight-line method over the following estimated useful lives: • Buildings - 15 to 39 years • Furniture, fixture, and equipment - 3 to 10 years • Computer equipment - 1 to 5 years • Computer software - 1 to 5 years • Leasehold improvement - life of lease or improvements, whichever is shorter
BOLI	BOLI —The Company has purchased life insurance policies on certain key executives and directors. BOLI is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Investments in Affordable Housing Partnerships	Investments in Affordable Housing Partnerships —The Company owns limited partnership interests in projects of affordable housing for lower income tenants. Under the equity method of accounting, the annual amortization is based on the estimated tax deduction amounts the bank would receive in the year. The carrying value of such investments and commitments to fund investment in affordable housing is recorded as “Investments in affordable housing partnerships” in the Consolidated Statement of Financial Condition. Commitments to fund investments in affordable housing is also included in this line items but is also grossed up and recorded as a liability.
Leases	Leases —operating lease right-of-use (“ROU”) assets represent the Company’s right to use the underlying asset during the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the future lease payments using the Company’s incremental borrowing rate. The Company calculates its incremental borrowing rate by adding a spread to the FHLB borrowing interest rate at a given period. The Company does not capitalize short-term leases, which are leases with terms of twelve months or less. ROU assets and related operating lease liabilities are remeasured when lease terms are amended, extended, or when management intends to exercise available extension options. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term and is recorded in occupancy expense in the consolidated statements of income. The Company’s occupancy expense also includes variable lease costs which is comprised of the Company's share of actual costs for utilities, common area maintenance, property taxes, and insurance that are not included in lease liabilities and are expensed as incurred. Variable lease costs also include rent escalations based on changes to indices, such as the Consumer Price Index.
Goodwill and Intangible Assets	Goodwill and Intangible Assets— Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any non-controlling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized but tested for impairment at least annually. In accordance with ASC 350 “ Intangibles - Goodwill and Other ”, the Company makes a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying the two-step goodwill impairment test. If management concludes that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, the step 1 impairment test is bypassed. Management assessed the qualitative factors related to goodwill as of December 31, 2020 and determined a Step 1 fair value assessment was required. Based on this assessment, management determined that goodwill was not impaired at December 31, 2020. Goodwill is also tested for impairment on an interim basis if circumstances change or an event occurs between annual tests that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Due to the effects of the COVID-19 pandemic in 2020, the Company performed an interim goodwill impairment assessment for each quarter of 2020. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, calculation of a terminal growth rate, minimum target capitalization levels, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The selection and weighting of the various fair value techniques may result in a higher or lower fair value. Judgment is applied in determining the weighting that is most representative of fair value. seven ten
Loan Servicing Assets	Loan Servicing Assets— The Company previously sold the guaranteed portion of SBA loans and retained the unguaranteed portion (“retained interest”). However, starting December 2018, the Company has chosen to retain the guaranteed portion of SBA loans. A portion of the premium on sale of SBA loans is recognized as gain on sale of loans at the time of the sale by allocating the carrying amount between the asset sold and the retained interest, including these servicing assets, based on their relative fair values. The remaining portion of the premium is recorded as a discount on the retained interest and is amortized over the remaining life of the loan as an adjustment to yield. The retained interest, net of any discount, are included in loans receivable—net of allowance for credit losses in the accompanying consolidated statements of financial condition. Servicing assets are recognized when SBA and residential mortgage loans are sold with servicing retained with the income statement effect recorded in gains on sales of loans. Servicing assets are initially recorded at fair value based on the present
Stock-Based Compensation	Stock-Based Compensation— Compensation cost is recognized for stock options and restricted stock awards issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.
Income Taxes	Income Taxes —Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred income tax assets and liabilities represent the tax effects, based on current tax law, of future deductible or taxable amounts attributable to events that have been recognized in the financial statements. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, the projected future taxable income and tax planning strategies in making this assessment. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and / or penalties related to income tax matters in income tax expense. Section 382 of the Internal Revenue Code imposes a limitation (“382 Limitation”) on a corporation’s ability to use any net unrealized built in losses and other tax attributes, such as net operating loss and tax credit carry-forwards, when it undergoes a 50% ownership change over a designated testing period not to exceed three years (“382 Ownership Change”). As a result of the acquisition on July 29, 2016, Wilshire Bancorp underwent a 382 Ownership Change resulting in a 382 Limitation to its net operating loss and tax credit carry-forwards. Wilshire Bancorp did not have a net unrealized built in loss as of the 382 Ownership Change date. Given the applicable 382 Limitation, the Company is expected to fully utilize Wilshire Bancorp’s net operating loss and tax credit carry-forwards before expiration. However, future transactions, such as issuances of common stock or sales of shares of the Company’s stock by certain holders of the Company’s shares, including persons who have held, currently hold or may accumulate in the future 5% or more of the Company’s outstanding common stock for their own account, could trigger a future Section 382 Ownership Change of the Company which could limit the Company’s use of these tax attributes.
Earnings per Common Share	Earnings per Common Share —Basic Earnings per Common Share is computed by dividing net income by the weighted-average number of common shares outstanding for the period. Diluted Earnings per Common Share reflects the potential dilution of common shares that could share in the earnings of the Company.
Equity	Equity —The Company accrues for common stock dividends as declared. Common stock dividends of $69.2 million and $70.9 million, were paid in 2020 and 2019, respectively. There were no common stock dividends declared but unpaid at December 31, 2020 and 2019.
Comprehensive Income	Comprehensive Income —Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes the change in unrealized gains and losses on securities available for sale and interest rate swaps used in cash flow hedges which is also recognized as separate components of stockholders’ equity, net of tax.
Operating Segments	Operating Segments—The Company is managed as a single business segment. The financial performance of the Company is reviewed by the chief operating decision maker on an aggregate basis and financial and strategic decisions are made based on the Company as a whole. “Banking Operations” is considered to be the Company’s single combined operating segment, which raises funds from deposits and borrowings for loans and investments, and provides lending products, including construction, real estate, commercial, and consumer loans to its customers.
Loss Contingencies and Loan Commitments and Related Financial Instruments	Loss Contingencies —Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. The Company believes there are no such matters that would have a material effect on the consolidated financial statements as of December 31, 2020 or 2019. Accrued loss contingencies for all legal claims totaled approximately $1.3 million at December 31, 2020 and $440 thousand at December 31, 2019.
Allowance For Unfunded Commitments	Allowance for Unfunded Commitments— The allowance for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to these unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. The allowance for unfunded commitments is included in other liabilities on the consolidated statement of financial condition, with changes to the balance charged against noninterest expense.
Fair Values of Financial Instruments	Fair Values of Financial Instruments —Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets— The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. If the estimated future cash flows (undiscounted) over the remaining useful life of the asset are less than the carrying value, an impairment loss would be recorded to reduce the related asset to its estimated fair value.
Transfers of Financial Assets	Transfer of Financial Assets —Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Use of Estimates in the Preparation of Consolidated Financial Statements	Use of Estimates in the Preparation of Consolidated Financial Statements —The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates.
Reclassifications	Reclassifications - Some items in the prior year financial statements were reclassified to conform to the current presentation. The reclassifications had no effect on the prior year net income or stockholders’ equity.
Recent Accounting Pronouncements and Newly Issued But Not Yet Effective Accounting Pronouncements	Accounting Pronouncements Adopted In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, also referred to as “CECL”. The FASB subsequently issued ASU 2018-19, ASU 2019-04, ASU 2019-05, ASU 2019-10, ASU 2019-11 and ASU 2020-02 to provide additional clarification, implementation, codification improvements, transition guidance, and adoption guidance related to ASU 2016-13. ASU 2016-13 requires the measurement of all expected credit losses for financial assets carried at amortized cost held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. On January 1, 2020, the Company adopted CECL using the modified retrospective approach. The adoption of the standard resulted in changes to the Company’s loan and allowance policies. Refer to Note 1 to the Consolidated Financial Statements in the Company’s 2019 Annual Report on Form 10-K regarding additional significant accounting policies, including accounting policies in effect prior to the adoption of CECL. Upon adoption of CECL accounting standard on January 1, 2020, the Company recognized a day 1 increase of its Allowance for Credit Losses (“ACL”) of $26.7 million. The Company adopted CECL without electing the fair value option on eligible financial instruments. Internal controls related to the CECL ACL calculation were finalized prior to adoption. The increase in the ACL was largely driven by longer duration CRE loans due to the capture of lifetime expected credit losses under CECL. On January 1, 2020, the Company also recorded a cumulative-effect adjustment, net of taxes, totaling $18.9 million to decrease retained earnings. In accordance with the revised regulatory CECL transition guidance, the Company has elected to defer the regulatory capital impact of the adoption of CECL for two years, at which time the impact will be phased-in over a three year period. The Company did not record an ACL on its available for sale securities upon adoption of CECL or as of December 31, 2020. The Company adopted CECL using the prospective transition approach for purchased credit deteriorated (“PCD”) assets which were previously classified as purchased credit impaired (“PCI”) and accounted for under ASC 310-30. In accordance with the CECL standard, the Company did not reassess whether PCI assets met the definition of PCD assets as of the date of the adoption of CECL. On January 1, 2020, the amortized cost basis of the PCD assets of $95.0 million were adjusted to reflect the ACL for loans. The remaining noncredit discount of $23.3 million at December 31, 2020, based on the adjusted amortized cost basis will be accreted into interest income at the effective interest rate over the life of the PCD loans. Under the CECL ACL methodology, losses are estimated for life of loans split out into three different periods. The initial period uses a forecast of two years for its portfolio segments using economic scenarios from an independent third party to estimate losses. Subsequent to the forecast period, a one year reversion period is used which connects the forecast period to last period of historical loss estimates. In January 2017, the FASB issued ASU 2017-04, “Intangibles: Goodwill and Other: Simplifying the Test for Goodwill Impairment.” ASU 2017-04 will amend and simplify current goodwill impairment testing to eliminate Step 2 from the current provisions. Under the new guidance, an entity should perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying value and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. An entity still has the option to perform the quantitative assessment for a reporting unit to determine if a quantitative impairment test is necessary. The adoption of ASU 2017-04 did not have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement”. ASU 2018-13 modifies the disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. ASU 2018-13 removes the disclosure requirement detailing the amount of and reasons for transfers between Level 1 and Level 2, and the valuation processes for Level 3 fair value measurements. In addition, ASU 2018-13 modifies the disclosure requirements for investments in certain entities that calculate net asset value. Lastly, ASU 2018-13 adds a disclosure requirement for changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 measurements. The adoption of ASU 2018-13 did not have a material impact on the Company’s consolidated financial statements. Pending Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform: Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments provide temporary, optional guidance to ease the potential burden in accounting for reference rate reform. The amendments provide optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. The amendments primarily include relief related to contract modifications and hedging relationships, as well as providing a one-time election for the sale or transfer of debt securities classified as held-to-maturity. This guidance is effective immediately and the amendments may be applied prospectively through December 31, 2022. The Company is currently in the process of evaluating ASU 2020-04 and determining the impact to the Company’s consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40)”. ASU 2020-06 eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. The new guidance also modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted EPS computation. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, including interim periods within those annual periods. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those annual periods. ASU 2020-06 allows companies to adopt the guidance through either a modified retrospective method of transition or a fully retrospective method of transition. On January 1, 2021, the Company early adopted ASU 2020-06 using the modified retrospective method of transition and had a cumulative effect adjustment to its retained earnings totaling $10.7 million. The Company’s convertible notes are currently recorded as separate debt and equity components. After the Company adopted ASU 2020-06, its convertible notes are accounted for as a single debt instrument. As a result, the Company will have a decline in reported interest expense with the elimination of the existing debt discount.
Fair Value Measurements	Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date reflecting assumptions that a market participant would use when pricing an asset or liability. There are three levels of inputs that may be used to measure fair value. The fair value inputs of the instruments are classified and disclosed in one of the following categories pursuant to ASC 820: Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. The quoted price shall not be adjusted for any blockage factor (i.e., size of the position relative to trading volume). Level 2 - Pricing inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Fair value is determined through the use of models or other valuation methodologies, including the use of pricing matrices. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 3 - Pricing inputs are unobservable for the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. The inputs into the determination of fair value require significant management judgment or estimation. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The Company uses the following methods and assumptions in estimating fair value disclosures for financial instruments. Financial assets and liabilities recorded at fair value on a recurring and non-recurring basis are listed as follows: Securities Available for Sale The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The fair values of the Company’s Level 3 securities available for sale were measured using an income approach valuation technique. The primary inputs and assumptions used in the fair value measurement were derived from the securities’ underlying collateral which included discount rates, prepayment speeds, payment delays, and an assessment of the risk of default of the underlying collateral, among other factors. Significant increases or decreases in any of the inputs or assumptions could result in a significant increase or decrease in the fair value measurement. Equity Investments With Readily Determinable Fair Value The fair value of the Company’s equity investments with readily determinable fair value is comprised of mutual funds. The fair value for these investments is obtained from unadjusted quoted prices in active markets on the date of measurement and is therefore classified as Level 1. Interest Rate Swaps The Company offers interest rate swaps to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The fair value of these derivatives is based on a discounted cash flow approach. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of interest rate swaps is classified as Level 2. Mortgage Banking Derivatives Mortgage banking derivative instruments consist of interest rate lock commitments and forward sale contracts that trade in liquid markets. The fair value is based on the prices available from third party investors. Due to the observable nature of the inputs used in deriving the fair value, the valuation of mortgage banking derivatives are classified as Level 2. Other Derivatives Other derivatives consist of interest rate swaps designated as cash flow hedges and risk participation agreements. The fair values of these other derivative financial instruments are based upon the estimated amount the Company would receive or pay to terminate the instruments, taking into account current interest rates and, when appropriate, the current credit worthiness of the counterparties. Interest rate swaps designated as cash flow hedges are classified within Level 2. Credit derivatives such as risk participation agreements are valued based on credit worthiness of the underlying borrower which is a significant unobservable input and therefore is classified as Level 3. Collateral Dependent Loans The fair values of collateral dependent loans are generally measured for ACL using the practical expedients permitted by ASC 326-20-35-5 including collateral dependent loans measured at an observable market price (if available), or at the fair value of the loan’s collateral (if the loan is collateral dependent). Fair value of the loan’s collateral, when the loan is dependent on collateral, is determined by appraisals or independent valuation, less costs to sell of 8.5%. Appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and income approach. Adjustment may be made in the appraisal process by the independent appraiser to adjust for differences between the comparable sales and income data available for similar loans and the underlying collateral. For commercial and industrial and asset backed loans, independent valuations may include a 20-60% discount for eligible accounts receivable and a 50-70% discount for inventory. These result in a Level 3 classification. OREO OREO is fair valued at the time the loan is foreclosed upon and the asset is transferred to OREO. The value is based primarily on third party appraisals, less costs to sell of up to 8.5% and result in a Level 3 classification of the inputs for determining fair value. OREO is reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted to lower of cost or market accordingly, based on the same factors identified above. Loans Held for Sale Loans held for sale are carried at the lower of cost or fair value, as determined by outstanding commitments from investors, or based on recent comparable sales (Level 2 inputs), if available, and if not available, are based on discounted cash flows using current market rates applied to the estimated life and credit risk (Level 3 inputs) or may be assessed based upon the fair value of the collateral which is obtained from recent real estate appraisals (Level 3 inputs). These appraisals may utilize a single valuation approach or a combination of approaches including the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in Level 3 classification of the inputs for determining fair value.
