SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations: Banc of California, Inc., a Maryland corporation, was incorporated in March 2002 and serves as the holding company for its wholly owned subsidiary, Banc of California, National Association (the “Bank”), a California-based bank. When we refer to the “parent” or the “holding company", we are referring to Banc of California, Inc., the parent company, on a stand-alone basis. When we refer to “we,” “us,” “our,” or the “Company”, we are referring to Banc of California, Inc. and its consolidated subsidiaries including the Bank, collectively. We are regulated as a bank holding company by the FRB and the Bank operates under a national bank charter issued by the OCC, the Bank's primary regulator. The Bank is a member of the FHLB system, and maintains insurance on deposit accounts with the FDIC. The Bank offers a variety of financial services to meet the banking and financial needs of the communities it serves, with operations conducted through 32 full-service branches extending from San Diego to Santa Barbara as of December 31, 2021. Basis of Presentation: The accom panying consolidated financial statements include the accounts of the Company and the Bank. All significant intercompany balances and transactions have been eliminated in consolidation. The accounting and reporting policies of the Company are based upon U.S. generally accepted accounting principles, which we may refer to as “GAAP,” and conform to predominant practices within the financial services industry. Certain prior period amounts have been reclassified to conform to current period presentation . For the year ended December 31, 2020, $2.5 million in noninterest expense was reclassified from “all other expense” to “extinguishment of debt” in the accompanying consolidated statement of operations. Significant accounting policies followed by the Company are presented below. Use of Estimates in the Preparation of Financial Statements: The preparation of financial statements, in conformity with GAAP, requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the consolidated financial statements and disclosures provided, and actual results could differ. The ACL (which includes the ALL and the reserve for unfunded loan commitments), loan repurchase reserve, realization of deferred tax assets, the fair value of assets and liabilities acquired in business combinations and related purchase price allocation, the valuation of goodwill and other intangible assets, other derivatives, HLBV of investments in alternative energy partnerships, and the fair value measurement of financial instruments are particularly subject to change and such change could have a material effect on the consolidated financial statements. Segment Reporting: We regularly assess our strategic plans, operations and reporting structures to identify our reportable segments. Changes to our reportable segments are expected to be infrequent. We operate one reportable segment — Commercial Banking. The factors considered in making this determination include the nature of products and services offered, geographic regions in which we operate and how information is reviewed by the chief executive officer and other key decision makers. As a result, we determined that all services we offer relate to Commercial Banking. Variable Interest Entities (“VIE”): We hold ownership interests in certain special purpose entities. We evaluate our interest in these entities to determine whether they meet the definition of a VIE and whether we meet the criteria as their primary beneficiary and are therefore required to consolidate these entities. A primary beneficiary of a VIE is defined as the party that has both the power to direct the activities that most significantly impact the VIE and a variable interest that could be significant to the VIE. A variable interest is a contractual ownership or other interest that changes with changes in the fair value of the VIE’s net assets. To determine whether or not a variable interest we hold could be significant to the VIE, we consider both qualitative and quantitative factors regarding the nature, size and form of our involvement with the VIE. We continually analyze whether we are the primary beneficiary of a VIE. Changes in facts and circumstances occurring since the previous primary beneficiary determination are considered as part of this ongoing assessment. See Note 20 — Variable Interest Entities for additional information. Cash and Cash Equivalents: Cash and cash equivalents include cash on hand, cash items in transit, cash due from the Federal Reserve Bank and other financial institutions, and federal funds sold with original maturities less than 90 days. Banking regulations previously required that banks maintain a percentage of their deposits as reserves in cash or on deposit with the Federal Reserve Bank. On March 15, 2020, the FRB announced that it had reduced reserve requirement ratios to 0 percent effective on March 26, 2020, which represented the beginning of the next reserve maintenance period. The FRB took this action in light of the Federal Open Market Committee's announcement in 2019 that it intends to implement monetary policy in an ample reserves regime, where reserve requirements do not play a role. The FRB's action is intended to help support lending to households and businesses . Available-for-Sale Debt Securities: Available-for-sale debt securities are carried at fair value. Accreted discounts and amortized premiums are included in interest income using the interest method, and realized gains or losses from sales of securities are calculated using the specific identification method. Available-for-sale debt securities are analyzed for credit losses under ASC 326, which requires the Company to determine whether impairment exists as of the reporting date and whether that impairment is due to credit losses. An allowance for credit losses would be established for losses on available-for-sale debt securities due to credit losses and would be reported as a component of provision for credit losses. Accrued interest is excluded from our expected credit loss estimates. Available-for-sale debt securities are typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest. When available-for-sale debt securities are placed on nonaccrual status, unpaid interest recognized as interest income is reversed. Loans Held-For-Sale, Carried at Fair Value: Loans held-for-sale, carried at fair value, are generally conforming SFR mortgage loans that are originated and intended for sale in the secondary market, repurchased loans that were previously sold to GNMA and other GSEs, and loans sold to GNMA that are delinquent more than 90 days and subject to a unilateral purchase option by us. The fair value of loans held-for-sale is based on commitments outstanding from investors as well as what secondary market investors are currently offering for portfolios with similar characteristics. Interest income on loans held-for-sale under the fair value option is measured based on the contractual interest rate and reported in interest income on loans, including fees in the consolidated statements of operations. Loans: When a determination is made at the time of commitment to originate or purchase loans as held-for-investment, it is our intent to hold these loans to maturity or for the foreseeable future, subject to periodic review under our management evaluation processes, including asset/liability management . Loans, excluding purchased credit deteriorated (“PCD”) loans, that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, are recorded at the principal balance outstanding, net of charge-offs, unamortized purchase premiums and discounts, and deferred loan fees and costs. Amortization of deferred loan origination fees and costs or purchase premiums and discounts are recognized in interest income as an adjustment to yield over the terms of loans using the interest method. Deferred loan origination fees and costs on revolving lines of credit are amortized using the straight-line method. Interest on loans is credited to interest income as earned based on the interest rate applied to principal amounts outstanding. Interest income is accrued on the unpaid principal balance and is discontinued when management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that full collection of principal or interest becomes doubtful, regardless of the length of past due status. Generally, loans are placed on nonaccrual status when scheduled payments become past due for 90 days or more. When accrual of interest is discontinued, any unpaid accrued interest receivable is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. A charge-off is generally recorded at 180 days past due for SFR mortgage loans if the unpaid principal balance exceeds the fair value of the collateral less costs to sell. Commercial and industrial and commercial real estate loans financings are subject to a detailed review when 90 days past due to determine accrual status, or when payment is uncertain and a specific consideration is made to put a loan on nonaccrual status. A charge-off for commercial and industrial and commercial real estate loans is recorded when a loss is confirmed. Consumer loans, other than those secured by real estate, are typically charged off no later than 120 days past due. Acquired Loans : At acquisition date, loans are evaluated to determine whether they meet the criteria of a PCD loan. PCD loans are loans that in management's judgment have experienced more than insignificant deterioration in credit quality since origination. Factors that indicate a loan may have experienced more than insignificant credit deterioration include delinquency, downgrades in credit rating, non-accrual status, and other negative factors identified by management at the time of initial assessment. PCD loans are initially recorded at fair value, with the resulting non-credit discount or premium being amortized or accreted into interest income using the interest method. In addition to the fair value adjustment, at the date of acquisition, an allowance for credit losses (“ACL”) is established with a corresponding increase to the overall acquired loan balance. This initial ACL is determined using the Company's current expected credit losses methodology. Acquired loans that are not considered PCD loans (“non-PCD loans”) are recognized at fair value at the acquisition date, with the resulting credit and non-credit discount or premium being amortized or accreted into interest income using the interest method. In addition to the fair value adjustment, at the time of acquisition, the Company establishes an initial ACL through a charge to the provision for credit losses. This initial ACL is determined using the Company's current expected credit losses methodology. Subsequent to acquisition date, the allowance for credit losses for both PCD and non-PCD loans is determined using the same methodology to determine current expected credit losses that is applied to all other loans. Allowance for Credit Losses: The ACL is estimated on a quarterly basis and represents management’s estimate of current expected credit losses in the Company's loan portfolio. Pools of loans with similar risk characteristics are collectively evaluated while loans that no longer share risk characteristics with loan pools are evaluated individually. The ACL is established through the provision for credit loss expense. Loans deemed uncollectible are charged off and deducted from the allowance. Recoveries on loans previously charged off are added to the allowance. The ACL process involves subjective and complex judgments. Credit losses are not estimated for accrued interest receivable as interest that is deemed uncollectible is written off through interest income. Collective loss estimates are determined by applying loss factors, designed to estimate current expected credit losses, to amortized cost balances over the remaining life of the collectively evaluated portfolio. Loans with similar risk characteristics are aggregated into homogeneous pools. The ACL consists of: (i) a specific allowance established for current expected credit losses on loans individually evaluated, (ii) a quantitative allowance for current expected loan losses based on the portfolio and expected economic conditions over a reasonable and supportable forecast period that reverts back to long-term trends to cover the expected life of the loan; and (iii) a qualitative allowance including management overlays to capture factors and trends that are not adequately reflected in the quantitative allowance, including an evaluation of our underwriting, other credit-related processes, and other credit risk factors such as concentration risk. The need for a loan to be individually evaluated, based on current information and events, is when it no longer meets the risk characteristics of the similarly identified pool of financial assets to be collectively evaluated. We measure expected credit losses on all individually evaluated loans under the guidance of ASC 326, Receivables , primarily through the evaluation of collateral values and estimated cash flows expected to be collected. Cash receipts on individually evaluated loans for which the accrual of interest has been discontinued are applied first to principal and then to interest income. Prior to the adoption of ASC 326, individually evaluated loans were referred to as impaired loans. Expected credit losses are estimated over the contractual term of the loans, adjusted for estimated prepayments, as appropriate. The contractual term excludes expected extensions and renewals unless those extension or renewal options are included in the underlying contract and we do not have the ability to unconditionally cancel. The contractual term also excludes expected modifications unless management has a reasonable expectation, at the reporting period, that a troubled debt restructuring will be executed. The allowance for loan losses includes qualitative adjustments to bring the allowance to the level management believes is appropriate based on factors that have not otherwise been fully accounted for, including those described in the federal banking agencies' joint interagency policy statement on ALL. These factors include, among others, inherent imprecision in forecasting economic variables, including determining the depth and duration of economic cycles and their impact to relevant economic variables; qualitative adjustments based on our evaluation of different forecast scenarios and known recent events impacting relevant economic variables; data factors that address the risk that certain model inputs may not reflect all available information including (i) risk factors that have not been fully addressed in internal risk ratings, (ii) changes in lending policies and procedures, (iii) changes in the level and quality of experience held by lending management, (iv) imprecision in the risk rating system and (v) limitations in data available for certain loan portfolios. The ACL process also includes challenging and calibrating the model and model results against observed information, trends and events within the loan portfolio, among others. Prior to the adoption of ASC 326, we maintained an allowance for loan losses to absorb probable incurred losses inherent in the loan portfolio at the balance sheet date. The allowance for loan losses was based on ongoing assessment of the estimated probable losses presently inherent in the loan portfolio. In evaluating the level of the allowance for loan losses, management considered the types of loans and the amount of loans in the portfolio, peer group information, historical loss experience, adverse situations that may have affected the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. We have established credit risk management processes that include regular management review of the loan portfolio to identify problem loans. During the ordinary course of business, management may become aware of borrowers who may not be able to fulfill their contractual payment requirements within the loan agreements. Such loans are subject to increased monitoring. Consideration is given to placing these loans on nonaccrual status, assessing the need for additional allowance for credit loss, and partially or fully charging off the principal balance. The credit risk monitoring system is designed to identify loans with credit deterioration and potential problem loans, perform periodic evaluation of impairment, and determine the adequacy of the allowance for credit losses in a timely manner. In addition, management has adopted a credit policy that includes a credit review and control system that it believes should be effective in ensuring that we maintain an adequate ACL. Further, the Board of Directors provides oversight and guidance for the ACL process. At December 31, 2021, the following loan portfolio segments have been identified: • Commercial and industrial (general commercial and industrial, warehouse lending, and indirect/direct leveraged lending) • Commercial real estate • Multifamily • Small Business Administration (“SBA”) • Construction • SFR - 1st deeds of trust (generally SFR mortgage and other) • Other consumer (automotive and HELOC) We categorize loans into risk categories based on relevant information about the ability of borrowers to service their obligations such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. We analyze loans individually by classifying the loans as to credit risk. Loans secured by multifamily and commercial real estate properties generally involve a greater degree of credit risk. Because payments on loans secured by multifamily and commercial real estate properties are often dependent on the successful operation or management of the properties, repayment of these loans may be subject to adverse conditions in the real estate market or the economy. In addition, commercial and industrial loans are also considered to have a greater degree of credit risk due to the fact that commercial and industrial loans are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment of commercial and industrial loans may be substantially dependent on the success of the business itself (which, in turn, is often dependent, in part, upon general economic conditions). Within the commercial and industrial portfolio, warehouse credit facilities are considered to have a lesser degree of risk then other commercial and industrial loans. Warehouse credit facilities are secured by newly granted single family residential mortgages underwritten with current borrower financial information. SBA loans are similar to commercial and industrial loans, however, they have additional credit enhancement in the form of a guaranty provided by the U.S. Small Business Administration, for up to 85% of the loan amount for loans up to $150 thousand and 75% of the loan amount for loans of more than $150 thousand. We often sell the guaranteed portion of certain SBA loans into the secondary market. The availability of funds for the repayment of financing may be substantially dependent on the success of the business itself which is often dependent, in part, upon general economic conditions. Included in SBA loans are the loans originated as part of the PPP established by the CARES Act, which have additional credit enhancement provided by the U.S. Small Business Administration for up to 100% of the loan amount. As of December 31, 2021, PPP loans totaled $123.1 million, net of $772 thousand in unamortized fees which are being amortized over their estimated life. The Company estimated the average life of our PPP loans to be 12 months to 18 months based on our understanding of our clients' cash use, expected forgiveness probability, and loan forgiveness process. Consumer loans have credit risk given that collection of these loans is dependent on the borrower’s continuing financial stability and, thus, are more likely to be adversely affected by job loss, divorce, illness, or personal bankruptcy. Green Loans are SFR first and second mortgages lines of credit with a linked checking account that allows all types of deposits and withdrawals to be performed. Green Loans are considered to carry a higher degree of credit risk than the general SFR portfolio due to their unique cash flows. Credit risk on this asset class is also managed through the completion of regular third party AVMs of the underlying collateral and monitoring of the borrower’s usage of this account to determine if the borrower is making monthly payments from external sources or “drawdowns” on their line. In cases where the property values have declined to levels less than the original LTV ratios, or other levels deemed prudent by us, we may curtail the line and/or require monthly payments or principal reductions to bring the loan in balance. On interest only loans, we project future payment changes to determine if there will be a material increase in the required payment and then monitor the loans for possible delinquency. Individual loans are monitored for possible downgrading of risk rating. Troubled Debt Restructurings: A loan is identified as a TDR when a borrower is experiencing financial difficulties and, for economic or legal reasons related to these difficulties, we grant a concession (or we reasonably expect to grant a concession) to the borrower in the restructuring that we would not otherwise consider. We have granted a concession when, as a result of the restructuring to a troubled borrower, we do not expect to collect all amounts due, including principal and/or interest accrued at the original terms of the loan. The concessions may be granted in various forms, including a below-market change in the stated interest rate, a reduction in the loan balance or accrued interest, an extension of the maturity date, or a note split with principal forgiveness. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under our internal underwriting policy. Loans for which the borrower has been discharged under Chapter 7 bankruptcy are considered collateral dependent TDRs, and charged down to the fair value of collateral less cost to sell. A restructuring executed at an interest rate that is at market interest rates based on the current credit characteristics of the borrower is not a TDR. Our policy is to place consumer loan TDRs, except those that were performing prior to TDR status, on nonaccrual status for a minimum period of 6 months. Commercial TDRs are evaluated on a case-by-case basis for determination of whether or not to place them on nonaccrual status. Loans qualify for return to accrual status once they have demonstrated performance under the restructured terms of the loan for a minimum of 6 months. Generally, TDRs are reported as TDRs for the remaining life of the loan. TDR classification may be removed if the borrower demonstrates compliance with the modified terms for a minimum of 6 months, through one fiscal year-end and the restructuring agreement specifies a market rate of interest equal to that which would be provided to a borrower with similar credit at the time of restructuring. In the limited circumstance that a loan is removed from TDR classification, it is our policy to continue to base our measure of loan impairment on the contractual terms specified by the loan agreement. TDR Relief: In order to encourage banks to work with impacted borrowers, the CARES Act and U.S. banking regulatory agencies have provided relief from TDR accounting on loans which qualify under the relevant provisions of the CARES Act or the “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus” on March 22, 2020 and revised April 7, 2020. The main provisions of TDR relief include 1) a capital provision in the form of reduced risk-weighted assets, as TDRs are more heavily risk-weighted for capital purposes; 2) a delinquency status provision, as the aging of loans are frozen, i.e., they will continue to be reported in the same delinquency status they were in at the time of modification; and 3) a nonaccrual status provision as the loans are generally not reported as nonaccrual or TDRs during the modification period. Reserve for Unfunded Loan Commitments: The reserve for unfunded loan commitments provides for current estimated credit losses for the unused portion of collective pools of lending commitments expected to be funded, except for unconditionally cancellable commitments for which no reserve is required under ASC 326. The reserve for unfunded loan commitments includes reserve factors that are consistent with the ACL methodology for loans using the expected loss factors and an estimated utilization or probability of draw factor, which are based on historical experience. Changes in the reserve for unfunded loan commitments are reported as a component of provision for credit losses in the consolidated statements of operations and the reserve for unfunded loan commitments is included in accrued expenses and other liabilities in the consolidated statements of financial condition. Fair Values of Financial Instruments: We measure certain assets and liabilities on a fair value basis, in accordance with ASC Topic 820, "Fair Value Measurement." Fair value is used on a recurring basis for certain assets and liabilities in which fair value is the primary basis of accounting. Examples of these include derivative instruments and available-for-sale securities. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment in accordance with ASC Topic 825, "Financial Instruments." Examples of these include loans individually evaluated for credit losses, long-lived assets, OREO, goodwill, and core deposit intangible assets as well as loans held-for-sale accounted for at the lower of cost or fair value. Fair value is the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants. When observable market prices are not available, fair value is estimated using modeling techniques such as discounted cash flow analysis. These modeling techniques utilize assumptions that market participants would use in pricing the asset or the liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset, and the risk of nonperformance. Depending on the nature of the asset or liability, we use various valuation techniques and assumptions when estimating the instrument’s fair value. Considerable judgment may be involved in determining the amount that is most representative of fair value. To increase consistency and comparability of fair value measures, ASC Topic 820, "Fair Value Measurement" established a three-level hierarchy to prioritize the inputs used in valuation techniques between observable inputs among (i) observable inputs that reflect quoted prices in active markets, (ii) inputs other than quoted prices with observable market data, and (iii) unobservable data such as our own data or single dealer non-binding pricing quotes. We assess the valuation hierarchy for each asset or liability measured at the end of each quarter; as a result, assets or liabilities may be transferred within hierarchy levels due to changes in availability of observable market inputs to measure fair value at the measurement date. Federal Home Loan Bank and Federal Reserve Bank Stock: The Bank is a member of the FHLB and FRB system. Members are required to own a certain amount of FHLB and FRB stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB and FRB stock are 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 on the consolidated statements of operations under interest and dividend income from other interest-earning assets. Other Real Estate Owned (“OREO"): OREO, which represents real estate acquired through foreclosure in satisfaction of commercial and real estate loans, is initially recorded at fair value less estimated selling costs of the real estate, based on current independent appraisals obtained at the time of acquisition, less costs to sell when acquired, establishing a new cost basis. Loan balances in excess of fair value of the real estate acquired at the date of acquisition are charged off against the ACL. A valuation allowance is established for any subsequent declines in fair value less estimated selling costs and adjusted as applicable. Gains and losses on the sale of OREO and reductions in fair value subsequent to foreclosure, and any subsequent operating expenses or income of such properties are included in all other expense on the consolidated statements of operations. Premises and Equipment: Land is carried at cost. Premises and equipment are recorded at cost less accumulated depreciation. The straight-line method is used for depreciation with the following estimated useful lives: building - 40 years and leasehold improvements - shorter of useful life or life of lease, and furniture, fixtures, and equipment - 3 to 7 years. Maintenance and repairs are expensed as incurred and improvements that extend the useful lives of assets are capitalized. Premises and equipment are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value, less selling costs. For impairment purposes, fair value is determined utilizing market values of similar assets or replacement cost as applicable. Bank Owned Life Insurance: The Bank has purchased life insurance policies on certain key employees. BOLI is recorded at the amount that can be realized under the insurance contract, which is the cash surrender value. Leases: Leases are accounted for in accordance with ASC 842 - Leases. We review contracts to determine if an arrangement contains a lease. At contract inception an operating lease right-of-use (“ROU”) asset is recognized with a corresponding lease liability based on the present value of future lease payments over the lease term. While operating leases may include options to extend the term, these options are not included when calculating the ROU asset and lease liability unless it is reasonably certain such options will be exercised. The present value of lease payments is determined using our incremental borrowing rate if the rate is not implicit in the lease. Our incremental borrowing rate is an actual borrowing rate with comparable terms or the published FHLB Advance borrowing rate at or near the lease commencement date for a comparable maturity. Leases with an initial term of 12 months or less are not recorded in the consolidated balance sheets. Our lease agreements include both lease and non-lease components (such as common area maintenance), which are generally included in the lease and are accounted for together with the lease as a single lease component. Expense for operating leases is recognized on a straight line basis and sublease income is included as a component of lease expense. Operating lease ROU assets are regularly reviewed for impairment. Business Combinations: Business combinations are accounted for using the acquisitio

Business Combination and Asset Acquisition [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS On October 18, 2021, we completed the PMB Acquisition, pursuant to which PMB merged with and into the Company, with the Company as the surviving corporation. PMB was the bank holding company of the wholly-owned Pacific Mercantile Bank, a California state chartered commercial bank headquartered in Costa Mesa, California, and operated seven banking offices, including three full service branches, located throughout Southern California. PMB's size, business focus, and deposit profile aligned with our operations and is expected to accelerate our growth and operating scale in key markets. Under the terms and conditions of the merger, each outstanding share of PMB common stock, aggregating 23,713,437 shares, was converted into the right to receive 0.5 (the “Exchange Ratio”) of a share of the Company's common stock. In addition, at the effective time of the merger, the Company paid $3.2 million in cash for all outstanding PMB share-based awards, including outstanding shares subject to unvested restricted stock awards. In the merger, the Company issued 11,856,713 shares of common stock with an estimated fair value of $222.2 million based upon the $18.74 closing price of the Company's common stock on October 18, 2021. Together with the $3.2 million of cash consideration, this result in an aggregate purchase price of $225.4 million. Goodwill in the amount of $57.2 million was recognized and represents the synergies and economies of scale expected from combining the operations of PMB with ours. Goodwill is not expected to be deductible for tax purposes. The following table represents a preliminary allocation of merger consideration to the assets and liabilities of PMB as of October 18, 2021 and the preliminary fair value amounts at acquisition date: ($ in thousands) Fair Value (1) Assets acquired: Cash and due from banks $ 3,196 Interest-earning deposits in financial institutions 475,554 Loans receivable 962,856 Allowance for credit losses (13,622) Premises and equipment, net 314 Operating lease right-of-use assets 9,212 Other intangible assets, net 5,054 Income tax receivable 2,035 Deferred income tax, net 10,660 Bank owned life insurance investment 9,043 Other assets 20,302 Total assets acquired $ 1,484,604 Liabilities assumed: Deposits $ 1,284,714 Long term debt, net 17,527 Lease liability 9,441 Accrued expenses and other liabilities 4,695 Total liabilities assumed 1,316,377 Excess of assets acquired over liabilities assumed 168,227 Consideration paid 225,384 Goodwill $ 57,157 (1) Estimated fair values are preliminary and subject to adjustment for a period of up to one year after the acquisition date as additional information related to fair value may become available. The preliminary fair value of the acquired identifiable intangible assets, representing core deposit intangibles, is $5.1 million. Core deposit intangible assets were valued using a net cost savings method and calculated as the present value of the estimated net cost savings attributable to the core deposit base over the expected remaining life of the deposits. The cost savings derived from the core deposit balance were calculated as the difference between the prevailing alternative cost of funds and the estimated cost of the core deposits. The core deposit intangible is being amortized on an accelerated basis over its estimated useful life of 10 years. During the year ended December 31, 2021, we incurred $15.9 million of costs to effect and integrate the Merger, which were expensed in accordance with ASC 805 and are included in merger-related costs in our consolidated statements of operations. These costs included investment banking fees, personnel costs, professional fees, facilities-related charges, systems conversion costs and other costs. The following table presents the total amounts of revenue and earnings of PMB since the acquisition included in our results of operations: Year Ended ($ in thousands) 2021 Net interest income $ 7,430 Noninterest income 528 Total revenue $ 7,958 Net loss $ (18,649) The following table presents unaudited pro forma total revenue and earnings as if the Acquisition occurred on January 1, 2020. This information is presented for informational purposes only. This information includes various estimates and may not necessarily be indicative of the financial condition or results of operations that would have occurred if the Acquisition had been completed at the beginning of the periods indicated or which may be obtained in the future. The pro forma information, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the opportunities to earn additional revenue and does not include assumptions as to cost savings and, accordingly, does not attempt to predict or suggest future results.

FAIR VALUES OF FINANCIAL INSTRU

FAIR VALUES OF FINANCIAL INSTRUMENTS	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUES OF FINANCIAL INSTRUMENTS	FAIR VALUES OF FINANCIAL INSTRUMENTS Fair Value Hierarchy ASC 820-10 establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The topic describes three levels of inputs that may be used to measure fair value: • Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2: Significant observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Assets and Liabilities Measured on a Recurring Basis Securities Available-for-Sale: The fair values of securities available-for-sale are generally determined by quoted market prices in active markets, if available (Level 1). We had no securities available-for-sale classified as Level 1 at December 31, 2021 and 2020. If quoted market prices are not available, we primarily employ independent pricing services that utilize pricing models to calculate fair value. Such fair value measurements consider observable data such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and respective terms and conditions for debt instruments. We employ procedures to monitor the pricing service's assumptions and establish processes to challenge the pricing service's valuations that appear unusual or unexpected. Multiple quotes or prices may be obtained in this process and we determine which fair value is most appropriate based on market information and analysis. Quotes obtained through this process are generally non-binding. We follow established procedures to ensure that assets and liabilities are properly classified in the fair value hierarchy. All securities available-for-sale were classified as Level 2 at December 31, 2021 and 2020. When a market is illiquid or there is a lack of transparency around the inputs to valuation, including at least one unobservable input, the securities are classified as Level 3 and reliance is placed upon internally developed models and management's judgment and evaluation for valuation. We had no securities available-for-sale classified as Level 3 at December 31, 2021 and 2020. Loans Held-for-Sale, Carried at Fair Value: The fair value of loans held-for-sale is based on commitments outstanding from investors and current offerings in the secondary market for portfolios with similar characteristics, except for loans that are repurchased out of GNMA loan pools that become severely delinquent which are valued based on an internal model. Loans held-for-sale subject to recurring fair value adjustments are classified as Level 2, or in the case of loans repurchased, Level 3. The fair value includes the servicing value of the loans and any accrued interest. Derivative Assets and Liabilities: Interest Rate Swaps and Caps. We offer interest rate swap and cap products to certain loan clients to allow them to hedge the risk of rising interest rates on their variable rate loans. We originate a variable rate loan and enter into a variable-to-fixed interest rate swap with the client. We also enter into an offsetting swap with a correspondent bank. These back-to-back agreements are intended to offset each other and allow us to originate a variable rate loan while providing a contract for fixed interest payments for the client. The net cash flow for us is equal to the interest income received from a variable rate loan originated with the client plus a fee. 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. Foreign Exchange Contracts. We offer short-term foreign exchange contracts to customers to purchase and/or sell foreign currencies at set rates in the future. These products allow customers to hedge the foreign exchange rate risk of their deposits and loans denominated in foreign currencies. In conjunction with these products, we also enter into offsetting contracts with institutional counterparties to hedge the Company’s foreign exchange rate risk. These back-to-back contracts allow us to offer our customers foreign exchange products while minimizing exposure to foreign exchange rate fluctuations. The fair value of these instruments is determined at each reporting period based on the change in the foreign exchange rate. Given the short-term nature of the contracts, the counterparties’ credit risks are considered nominal and result in no adjustments to the valuation of the short-term foreign exchange contracts. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of these contracts is classified as Level 2. The following table presents our financial assets and liabilities measured at fair value on a recurring basis as of the dates indicated: Fair Value Measurement Level ($ in thousands) Carrying Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs December 31, 2021 Assets Securities available-for-sale: SBA loan pools securities $ 14,591 $ — $ 14,591 $ — U.S. government agency and U.S. government sponsored enterprise residential mortgage-backed securities 191,969 — 191,969 — U.S. government agency and U.S. government sponsored enterprise collateralized mortgage obligations 241,541 — 241,541 — Municipal securities 119,015 — 119,015 — Non-agency residential mortgage-backed securities 56,025 — 56,025 — Collateralized loan obligations 518,964 — 518,964 — Corporate debt securities 173,598 — 173,598 — Loans held-for-sale, carried at fair value 3,408 — 2,415 993 Derivative assets: Interest rate swaps and caps (1) 3,390 — 3,390 — Foreign exchange contracts (1) 175 — 175 — Liabilities Derivative liabilities: Interest rate swaps and caps (2) 3,594 — 3,594 — Foreign exchange contracts (2) 146 — 146 — December 31, 2020 Assets Securities available-for-sale: SBA loan pools securities $ 17,354 $ — $ 17,354 $ — U.S. government agency and U.S. government sponsored enterprise residential mortgage-backed securities 106,384 $ — 106,384 $ — U.S. government agency and U.S. government sponsored enterprise collateralized mortgage obligations 211,831 — 211,831 — Municipal securities 68,623 — 68,623 — Non-agency residential mortgage-backed securities 160 — 160 — Collateralized loan obligations 677,785 — 677,785 — Corporate debt securities 149,294 — 149,294 — Loans held-for-sale, carried at fair value 1,413 — 468 945 Derivative assets: Interest rate swaps and caps (1) 7,304 — 7,304 — Foreign exchange contracts (1) 328 — 328 — Liabilities Derivative liabilities: Interest rate swaps and caps (2) 7,789 — 7,789 — Foreign exchange contracts (2) 313 — 313 — (1) Included in other assets in the consolidated statements of financial condition.

Loans repurchased from GNMA loan pools had aggregate unpaid principal balances of $1.0 million and $1.1 million at December 31, 2021 and 2020. The significant unobservable inputs used in the fair value measurement of our loans repurchased from GNMA loan pools at December 31, 2021 and December 31, 2020 included an expected loss rate of 1.55% for insured loans and 20.00% for uninsured loans. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. Fair Value Option Loans Held-for-Sale, Carried at Fair Value: We elected the fair value option for certain SFR mortgage loans held-for-sale. Electing to measure SFR mortgage loans held-for-sale at fair value reduces certain timing differences and better matches changes in the value of these assets with changes in the value of derivatives used as economic hedges for these assets, if any. We also elected to record loans repurchased from GNMA at fair value, as we intend to sell them after curing any defects and, accordingly, they are classified as held-for-sale. The following table presents the fair value and aggregate principal balance of certain assets under the fair value option: December 31, 2021 2020 ($ in thousands) Fair Value Unpaid Principal Balance Difference Fair Value Unpaid Principal Balance Difference Loans held-for-sale, carried at fair value in continuing operations: Total loans $ 3,408 $ 3,638 $ (230) $ 1,413 $ 1,680 $ (267) Nonaccrual loans (1) 128 143 (15) 654 750 (96) (1) Includes loans guaranteed by the U.S. government of $38 thousand and $190 thousand at December 31, 2021 and 2020. There were no loans held-for-sale that were 90 days or more past due and still accruing interest as of December 31, 2021 and 2020. The assets accounted for under the fair value option are initially measured at fair value. Gains and losses from initial measurement and subsequent changes in fair value are recognized in earnings. The following table presents changes in fair value related to initial measurement and subsequent changes in fair value included in earnings for these assets measured at fair value for the periods indicated: Year Ended December 31, ($ in thousands) 2021 2020 2019 Net gains (losses) from fair value changes Fair value adjustment for loans held-for-sale $ 206 $ (1,501) $ 106 Assets and Liabilities Measured on a Non-Recurring Basis Individually Evaluated Loans: The fair value of individually evaluated loans (previously referred to as impaired loans prior to the adoption of ASC 326) with specific allocations of the ALL based on collateral values is generally based on recent real estate appraisals and AVMs. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and 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 deemed significant unobservable inputs used for determining fair value and result in a Level 3 classification. Other Real Estate Owned Assets: OREO assets are initially recorded at fair value at the time of foreclosure. Thereafter, they are recorded at the lower of cost or fair value. The fair value of OREO assets is generally based on recent real estate appraisals adjusted for estimated selling costs. These appraisals may utilize a single valuation approach or a combination of approaches and adjustments are routinely made in the appraisal process resulting in a Level 3 classification due to the unobservable inputs used for determining fair value. We recorded impairment expense for OREO assets of zero, zero and $145 thousand for the years ended December 31, 2021, 2020 and 2019 in all other expense on the consolidated statements of operations.

Federal Home Loan Bank and Other Bank Stock: FHLB, Federal Reserve Bank and other bank stock are recorded at cost, which approximates fair value. Ownership of FHLB and Federal Reserve Bank stock is restricted to member banks, and purchases and sales of these securities are at par value with the issuer (Level 2). Loans Receivable, Net of ALL: The fair value of loans receivable, which is based on an exit price notion, is estimated based on the discounted cash flow approach. The discount rate was derived from the associated market yield curve plus appropriate spreads. The resulting fair value reflects market price for loans with similar financial characteristics. Yield curves are constructed by product and payment types. Additionally, the fair value of our loans may differ significantly from the values that would have been used had a ready market existed for such loans and may differ materially from the values that we may ultimately realize (Level 3). Accrued Interest Receivable: The carrying amount of accrued interest receivable approximates its fair value (Level 1). Deposits: The fair values of deposits with no stated maturity, including noninterest‑bearing deposits, interest-bearing demand deposits, money market and savings accounts are equal to the amount payable on demand as of the balance sheet date (Level 1). The fair value of certificates of deposit is estimated based on discounted cash flows utilizing interest rates currently being offered by the Bank on comparable deposits as to amount and remaining term (Level 2). Advances from Federal Home Loan Bank and Other Borrowings: The fair values of advances from FHLB and other borrowings are estimated based on a discounted cash flow approach. The discount rate was derived from the current market rates for borrowings with similar remaining maturities (Level 2). Long-Term Debt: Fair value of long-term debt is determined by observable data such as market spreads, cash flows, yield curves, credit information, and respective terms and conditions for debt instruments (Level 2). Accrued Interest Payable: The carrying amount of accrued interest payable approximates its fair value (Level 1).

The expected maturities of these types of securities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. There was no allowance for credit losses for debt securities as of December 31, 2021. Accrued interest receivable on debt securities available-for-sale totaled $4.7 million and $4.5 million at December 31, 2021 and December 31, 2020, and is included within other assets in the accompanying consolidated statements of financial condition. At December 31, 2021 and December 31, 2020, there were no holdings of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of our stockholders’ equity.

At December 31, 2020, our securities available-for-sale portfolio consisted of 103 securities, 50 of which were in an unrealized loss position. We monitor our securities portfolio to ensure it has adequate credit support. We consider the lowest credit rating for identification of credit impairment for collateralized loan obligations and other securities. The decline in fair value of our securities since acquisition was attributable to a combination of changes in interest rates and general volatility in the credit market conditions in response to the economic uncertainty caused by the global pandemic. We do not currently intend to sell any of the securities in an unrealized loss position and further believe, it is more likely than not, that we will not be required to sell these securities before their anticipated recovery. As of December 31, 2021, all of our collateralized loan obligation investment securities in an unrealized loss position received an investment grade credit rating. During the years ended December 31, 2021 and 2020, no allowance for credit losses related to securities available-for-sale was recorded. Prior to the adoption of CECL on January 1, 2020, losses related to securities available-for-sale were evaluated for OTTI. During the year ended December 31, 2019, we recorded OTTI for our remaining portfolio of mortgage-backed securities of $731 thousand. This OTTI was recognized as a result of our strategic decision to liquidate this longer duration portfolio.

Credit Quality Indicators We categorize loans into risk categories based on relevant information about the ability of borrowers to service their debt such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. We perform historical loss analysis that is combined with a comprehensive loan to value analysis to analyze the associated risks in the current loan portfolio. We analyze loans individually by classifying the loans as to credit risk. This analysis includes all loans delinquent over 60 days and non-homogeneous loans such as commercial and commercial real estate loans. We use the following definitions for risk ratings: Pass : Loans classified as pass are in compliance in all respects with the Bank’s credit policy and regulatory requirements, and do not exhibit any potential or defined weakness as defined under “Special Mention”, “Substandard” or “Doubtful”. 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 our credit position at some future date. Substandard : Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful : Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans.

Loans in Process of Foreclosure At December 31, 2021 and 2020, there were no consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings were in process according to local requirements of the applicable jurisdiction. Allowance for Credit Losses The ACL methodology uses a nationally recognized, third-party model that includes many assumptions based on historical and peer loss data, current loan portfolio risk profile including risk ratings, and economic forecasts including macroeconomic variables (MEVs) released by our model provider during December 2021. The December 2021 forecasts reflect a more favorable view of the economy (i.e. higher GDP growth rates and lower unemployment rates) compared to December 2020 forecasts. While the current forecasts generally reflect an improving economy with the availability of the vaccine and other factors, there continues to be uncertainty regarding the impact of inflation (lasting or transitory), COVID-19 variants, further government stimulus, supply chain issues, and the ultimate pace of the recovery. Accordingly, our economic assumptions, the resulting ACL level and resulting provision consider all of the potential uncertainties and underlying assumptions, both positive and negative. The ACL also incorporated qualitative factors to account for certain loan portfolio characteristics that are not taken into consideration by the third-party model including underlying strengths and weaknesses in various segments of the loan portfolio. As is the case with all estimates, the ACL is expected to be impacted in future periods by economic volatility, changing economic forecasts, underlying model assumptions, and asset quality metrics, all of which may be better than or worse than current estimates. The ACL process involves subjective and complex judgments as well as adjustments for numerous factors including those described in the federal banking agencies' joint interagency policy statement on ALL, which include underwriting experience and collateral value changes, among others.

During 2021, we recorded a $13.7 million initial allowance for credit losses established for PCD loans from the PMB Acquisition and an $11.3 million initial charge to provision for credit losses for all other loans and unfunded commitments acquired from PMB. During 2021, net charge-offs included $4.4 million related to a commercial and industrial loan acquired from PMB and a $2.0 million SBA relationship. During 2021, recoveries totaled $3.4 million and included $2.6 million of recoveries related to PCD loans acquired from PMB that were charged-off prior to acquisition date that we had a contractual right to receive. During 2020, a $16.1 million legacy shared national credit was resolved resulting in a charge-off of $10.7 million. During 2019, we recorded a $35.1 million charge-off of a line of credit originated in November 2017 to a borrower purportedly the subject of a fraudulent scheme. In connection with the $35.1 million charge-off, on October 22, 2019, the Bank filed a complaint in the U.S. District Court for the Southern District of California (Case CV '19 02031 GPC KSC) seeking to recover its losses and other monetary damages against Chicago Title Insurance Company and Chicago Title Company, asserting claims under RICO, 18 U.S.C § 1962 and for RICO Conspiracy, Fraud, Aiding and Abetting Fraud, Negligent Misrepresentation, Breach of Fiduciary Duty and Negligence. On October 2, 2020, the case was re-filed in the Superior Court of the State of California, County of San Diego (Case 37-2020-00034947) asserting claims for Fraud, Aiding and Abetting Fraud, Conspiracy to Defraud, Negligent Misrepresentation, Breach of Fiduciary Duty, Negligence, Money Had And Received, and Conversion. On February 9, 2021, an Amended Complaint was filed asserting claims for Fraud, Aiding and Abetting Fraud, Conspiracy to Defraud, Negligent Misrepresentation, Breach of Fiduciary Duty, Negligence, Money Had And Received, Conversion, Violation of Penal Code Section 496, Violation of Corporations Code Section 25504.1, and Violation of Business & Professions Code Section 17200. We are actively considering and pursuing available sources of recovery and other potential means of mitigating the loss; however, no assurance can be given that we will be successful in that regard. During the third quarter of 2019 and in response to the identified charge-off, we undertook an extensive collateral review of all commercial lending relationships $5.0 million and above not secured by real estate. The collateral review focused on security and collateral documentation and confirmation of the Bank's collateral interest. The review was performed within the Bank's Internal Audit division and the work was validated by an independent third party. Our review and outside validation did not identify any other instances of apparent fraud for the credits reviewed or concerns over the existence of collateral held by the Bank or on our behalf at third parties; however, there are no assurances that our internal review and third party validation were sufficient to identify all such issues. Accrued interest receivable on loans receivable, net totaled $25.8 million and $24.7 million at December 31, 2021 and 2020, and is included within other assets in the accompanying consolidated statements of financial condition.

Included in transfers to loans held for sale for the year ended December 31, 2019 is $573.9 million in multifamily loans from loans held-for-investment related to our completed Freddie Mac multifamily securitization which closed during the third quarter of 2019. The loans included in the securitization had a weighted average coupon of 3.79% and a weighted average term to initial reset of 3.5 years. The related mortgage servicing rights were also sold. Non-Traditional Mortgage (NTM) Loans As of December 31, 2021 and 2020, the NTM loans totaled $635.3 million, or 8.8% of total loans, and $437.1 million, or 7.4% of total loans, respectively. These SFR loans are included in our consumer portfolio and comprised of three interest only products: interest only loans, Green Loans, and a small number of additional loans with the potential for negative amortization. Interest only loans are primarily SFR first mortgage loans that generally have a 30 to 40-year term at the time of origination and include payment features that allow interest only payments in initial periods before converting to a fully amortizing loan. At December 31, 2021 and 2020, interest only loans totaled $613.3 million and $401.6 million. Green Loans are SFR first and second mortgage lines of credit with a linked checking account that allows all types of deposits and withdrawals to be performed. Green Loans are generally interest only for a 15-year term with a balloon payment due at maturity. At December 31, 2021 and 2020, Green Loans totaled $21.5 million and $33.2 million. Negative amortization loans totaled $0.5 million and $2.3 million at December 31, 2021 and 2020. We discontinued origination of negative amortization loans in 2007. We no longer originate SFR loans, however we have and may continue to purchase pools of loans that include NTM loans such as interest only loans with maturities of up to 40 years and flexible initial repricing dates, ranging from 1 to 10 years, and periodic repricing dates through the life of the loan. At December 31, 2021 and 2020, nonperforming NTM loans totaled $4.0 million and $8.7 million. Non-Traditional Mortgage Performance Indicators

Net proceeds after debt issuance costs and discount were approximately $172.8 million. The Senior Notes are unsecured debt obligations which rank equally with all of our other present and future unsecured unsubordinated obligations. We make interest payments on the Senior Notes semi-annually in arrears. We have the option to redeem the Senior Notes either in whole or in part on or after January 15, 2025 (i.e., 90 days prior to the maturity date). Notification of no less than 30 nor more than 60 days is required for redemption. The Senior Notes will be redeemable at a redemption price equal to 100% of the principal amount of the Senior Notes to be redeemed plus accrued and unpaid interest to the date of redemption. The Senior Notes were issued under the Senior Debt Securities Indenture, dated as of April 23, 2012 (the “Senior Notes Base Indenture”), as supplemented by the Second Supplemental Indenture dated as of April 6, 2015 (the “Senior Notes Supplemental Indenture” and together with the “Senior Notes Base Indenture”, the “Senior Notes Indenture”). The Senior Notes Indenture contains several covenants which, among other things, restrict our ability and the ability of our subsidiaries to dispose of or incur liens on the voting stock of certain subsidiaries and also contains customary events of default. We were in compliance with all covenants under the Senior Notes Indenture at December 31, 2021. Subordinated Notes On October 30, 2020, we completed the issuance and sale of $85.0 million aggregate principal amount of our 4.375% fixed-to-floating rate subordinated notes due October 30, 2030 (the “Subordinated Notes”). Net proceeds after debt issuance costs were approximately $82.6 million. The Subordinated Notes are unsecured debt obligations and subordinated to our present and future Senior Debt (as defined in the Subordinated Notes Indenture (as defined below)) and subordinated to all of our subsidiaries’ present and future indebtedness and other obligations. The Subordinated Notes bear interest at an initial fixed rate of 4.375% per annum, payable semi-annually in arrears. From and including October 30, 2025 to, but excluding, the maturity date or the date of earlier redemption, the Subordinated Notes bear interest at a floating rate per annum equal to a benchmark rate, which is expected to be 3-Month Term SOFR, plus a spread of 419.5 basis points, payable quarterly in arrears. We may, at our option, redeem the Subordinated Notes in whole or in part on October 30, 2025 and on any interest payment date thereafter. We may also, at our option, redeem the Subordinated Notes at any time, including prior to October 30, 2025, in whole but not in part, upon the occurrence of certain events. Any redemption of the Subordinated Notes will be subject to obtaining the prior approval of the FRB to the extent then required under the rules of the FRB, and will be at a redemption price equal to 100% of the principal amount of the Subordinated Notes plus any accrued and unpaid interest to, but excluding, the redemption date. The Subordinated Notes were issued under the Subordinated Debt Securities Indenture, dated as of October 30, 2020 (the “Subordinated Notes Base Indenture”), as supplemented by the Supplemental Indenture relating to the Subordinated Notes, dated as of October 30, 2020 (the “Subordinated Notes Supplemental Indenture,” and together with the Subordinated Notes Base Indenture, the “Subordinated Notes Indenture”). The Subordinated Notes Indenture contains several covenants and customary events of default. We were in compliance with all covenants under the Subordinated Notes Indenture at December 31, 2021. Junior Subordinated Debentures In connection with the PMB Acquisition, we assumed PMB's junior subordinated debentures. PMB had previously formed two grantor trusts to sell and issue to institutional investors floating rate trust preferred securities (“trust preferred securities”). The net proceeds from the sales of the trust preferred securities were used in exchange for PMB's issuance to the grantor trusts of PMB's junior subordinated floating rate debentures (the “Debentures”). The payment terms of the Debentures are used by the grantor trusts to make the payments that come due to the holders of the trust preferred securities pursuant to the terms of those securities. The Debentures also were pledged by the grantor trusts as security for the payment obligations of the grantor trusts under the trust preferred securities.

INCOME TAXES	INCOME TAXES The following table presents the components of income tax expense of continuing operations for the periods indicated: Year Ended December 31, ($ in thousands) 2021 2020 2019 Current income taxes: Federal $ 7,966 $ 7,332 $ 3,900 State 6,466 3,713 941 Total current income tax expense 14,432 11,045 4,841 Deferred income taxes: Federal 4,950 (5,663) (1,492) State 894 (3,596) 870 Total deferred income tax expense (benefit) 5,844 (9,259) (622) Income tax expense $ 20,276 $ 1,786 $ 4,219 The following table presents a reconciliation of the recorded income tax expense of continuing operations to the amount of taxes computed by applying the applicable statutory Federal income tax rate of 21.0% to income from continuing operations before income taxes for the years ended December 31, 2021, 2020, and 2019: Year Ended December 31, 2021 2020 2019 Computed expected income tax expense at Federal statutory rate 21.0 % 21.0 % 21.0 % Increase (decrease) resulting from: Proportional amortization 4.3 % 24.1 % 12.6 % Income tax credits (investment tax credits and other) (5.5) % (30.6) % (20.0) % Other permanent book-tax differences 0.9 % 1.9 % (2.4) % State tax expense, net of federal benefit 7.0 % 0.6 % 5.1 % Bank owned life insurance policies (0.7) % (3.6) % (1.7) % Equity compensation shortfall (windfall) tax impact (2.2) % 2.2 % 0.6 % Reserve for uncertain tax positions — % (0.9) % (1.0) % Other, net (0.3) % (2.3) % 0.9 % Effective tax rates 24.5 % 12.4 % 15.1 % During the year ended December 31, 2021, income tax expense included a $2.5 million tax benefit from share-based awards, including the exercise of all previously issued outstanding stock appreciation rights and other discrete tax items that impacted our effective tax rate. During the year ended December 31, 2021, our qualified affordable housing partnerships resulted in a reduction of our effective tax rate as the tax deductions and credits outpaced the increase in the effective tax rate due to higher proportional amortization. Our effective tax rate for the year ended December 31, 2021 was higher than the effective tax rate for the year ended December 31, 2020 due mainly to (i) higher pre-tax income, and (ii) lower net tax effects of our qualified affordable housing partnerships, offset by (iii) higher tax benefit from share-based awards of $2.5 million, primarily from the exercise of all previously issued outstanding stock appreciation rights in 2021. The Company’s effective tax rate for the year ended December 31, 2020 was lower than the effective tax rate for the year ended December 31, 2019 due mainly to (i) lower pre-tax income, (ii) lower state tax deductions, and (iii) the net tax effects of our qualified affordable housing partnerships and investments in alternative energy partnerships. During the year ended December 31, 2020 our qualified affordable housing partnerships resulted in a reduction of our effective tax rate as the tax deductions and credits outpaced the increase in the effective tax rate due to higher proportional amortization. At December 31, 2021, we had available gross unused federal NOL carryforwards of $821 thousand that may be applied against future taxable income through 2031. At December 31, 2021, we had available gross unused state NOL carryforwards of $34.8 million that may be applied against future taxable income through 2036. Utilization of these NOL carryforwards are subject to annual limitations set forth in Section 382 of the U.S. Internal Revenue Code. In addition, as of December 31, 2021 and 2020, we had income tax credit carryforwards of $23.0 million and $30.2 million. These tax credits, if unused, will expire in 2037. The following table presents the tax effects of temporary differences that give rise to significant portions of deferred tax assets and deferred tax liabilities as of the dates indicated: December 31, ($ in thousands) 2021 2020 Deferred tax assets: Allowance for loan losses $ 29,746 $ 24,032 Stock-based compensation expense 1,181 2,182 Accrued expenses 6,198 4,168 Loan repurchase reserve 1,256 1,625 Federal net operating losses 172 272 State net operating losses 2,762 686 Federal income tax credits 23,045 30,225 Deferred loan fees 1,692 1,998 Amortization of intangible assets — 1,198 Prior year state tax deduction 1,648 443 Lease liability 11,752 6,082 Other deferred tax assets 4,897 2,824 Total deferred tax assets 84,349 75,735 Deferred tax liabilities: Unrealized gain on securities available-for-sale (3,172) (3,236) Investments in partnerships (8,857) (8,139) Mortgage servicing rights (130) (167) Amortization of intangible assets (47) — Deferred loan costs (4,577) (5,154) Depreciation on premises and equipment (4,916) (5,618) Right of use asset (10,240) (5,784) Other deferred tax liabilities (1,636) (1,680) Total deferred tax liabilities (33,575) (29,778) Valuation allowance — — Net deferred tax assets $ 50,774 $ 45,957 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 will continue to evaluate both positive and negative evidence on a quarterly basis, including considering the four possible sources of future taxable income: (i) future reversal of existing taxable temporary differences, (ii) future taxable income exclusive of reversing temporary differences and carryforwards, (iii) taxable income in prior carryback year(s), and (iv) future tax planning strategies. Based on this analysis, management determined, it was more likely than not, that all of the deferred tax assets would be realized; therefore, no valuation allowance was provided against the net deferred tax assets at December 31, 2021 and 2020. We believe that the future reversing taxable temporary differences, the ability for the Company to utilize tax credits in 2021, and our projection of future taxable income should be considered significant positive evidence that the deferred tax assets for income tax credits will be realized in future periods prior to their expiration dates. ASC 740-10-25 relates to the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. ASC 740-10-25 prescribes a threshold and a measurement process for recognizing in the financial statements a tax position taken or expected to be taken in a tax return and also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. We had unrecognized tax benefits of $925 thousand and $924 thousand at December 31, 2021 and 2020. We do not believe that the unrecognized tax benefits will change materially within the next twelve months. As of December 31, 2021, the total unrecognized tax benefit that, if recognized, would impact the effective tax rate was $699 thousand. At December 31, 2021 and 2020, we had no accrued interest or penalties, respectively. The table below summarizes the activity related to our unrecognized tax benefits for the periods indicated: Year Ended December 31, ($ in thousands) 2021 2020 2019 Beginning balance $ 924 $ 977 $ 1,227 Decrease related to prior year tax positions (59) (6) (101) Increase in current year tax positions 60 120 120 Decrease related to lapsing of statute of limitations — (167) (269) Ending balance $ 925 $ 924 $ 977 In the event we are assessed interest and/or penalties by federal or state tax authorities, such amounts will be classified on the consolidated financial statements as income tax expense. We are subject to U.S. federal income tax as well as income tax in multiple state jurisdictions. The statute of limitations for examination by U.S. federal taxing authorities has expired for tax years before 2018. The statute of limitations for the assessment of California franchise taxes has expired for tax years before 2017 (other state income and franchise tax statutes of limitations vary by state). We account for low income housing tax credit investments under the proportional amortization method. The aggregate funding commitment in these investments totaled $61.3 million and the unfunded portion was $10.3 million as of December 31, 2021. The carrying value of these investments was $39.0 million and $43.2 million at December 31, 2021 and 2020. The proportional amortization of these investments amounted to $4.2 million, $5.3 million and $3.5 million for the years ended December 31, 2021, 2020 and 2019. The tax deduction from these investments totaled $3.7 million, $7.2 million and $7.8 million in 2021, 2020 and 2019. The unused tax credit carryforwards for these investments totaled $13.2 million and $9.0 million as of December 31, 2021 and 2020.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS We use derivative instruments and other risk management techniques to reduce our exposure to adverse fluctuations in interest rates and foreign currency exchange rates in accordance with our risk management policies. Refer to Note 1 — Significant Accounting Policies for additional information on our derivative instruments. During the years ended December 31, 2021, 2020 and 2019, changes in fair value of interest rate swaps and caps on loans and foreign exchange contracts were a net gain (loss) of $295 thousand, $(200) thousand, and $(9.2) million, and were included in other income on the consolidated statements of operations. During the year ended December 31, 2019, other income included a $9.0 million loss on interest rate swaps related to the Freddie Mac multifamily securitization in which we sold the associated mortgage servicing rights. The $9.0 million loss on these interest rate swaps was due to a decline in interest rates since their execution and was offset by the $8.9 million gross gain realized on the loans sold into the securitization in 2019. The following table presents the notional amount and fair value of derivative instruments included in the consolidated statements of financial condition as of the dates indicated.

Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY Preferred Stock We are authorized to issue 50,000,000 shares of preferred stock with par value of $0.01 per share. Preferred shares outstanding rank senior to common shares both as to dividends and liquidation preference but generally have no voting rights. All of our outstanding shares of preferred stock have a $1,000 per share liquidation preference. The following table presents our total outstanding preferred stock as of the dates indicated: December 31, 2021 2020 ($ in thousands) Shares Authorized and Outstanding Liquidation Preference Carrying Value Shares Authorized and Outstanding Liquidation Preference Carrying Value Series D 7.375% non-cumulative perpetual — $ — $ — 93,270 $ 93,270 $ 89,922 Series E 7.00% non-cumulative perpetual 98,702 98,702 94,956 98,702 98,702 94,956 Total 98,702 $ 98,702 $ 94,956 191,972 $ 191,972 $ 184,878 During certain periods, we have repurchased and redeemed Series D Depositary Shares and Series E Depositary Shares, each representing a 1/40th interest in a share of Series D Preferred Stock and Series E Preferred Stock. When the consideration paid to repurchase depositary shares exceeds such depositary shares' carrying value, the difference reduces net income allocated to common stockholders. When the consideration paid to repurchase depositary shares is less than such depositary shares' carrying value, the difference increases net income allocated to common stockholders. Redemptions of depositary shares are typically at par value. The following table summarizes repurchases and redemptions of these depositary shares during the periods indicated: Year Ended December 31, ($ in thousands) 2021 2020 2019 Series D Preferred Stock: Depositary shares repurchased or redeemed 3,730,767 134,410 734,823 Preferred Stock retired (shares) 93,269 3,360 18,371 Consideration paid $ 93,269 $ 2,698 $ 19,392 Carrying value 89,922 3,240 17,711 Impact of preferred stock redemption - Series D Preferred Stock (1) $ 3,347 $ (541) $ 1,681 Series E Preferred Stock: Depositary shares repurchased or redeemed — 70,967 980,928 Preferred Stock retired (shares) — 1,774 24,523 Consideration paid $ — $ 1,680 $ 27,005 Carrying value — 1,707 23,592 Impact of preferred stock redemption - Series E Preferred Stock (1) $ — $ (27) $ 3,412 Total impact of preferred stock redemption (1) $ 3,347 $ (568) $ 5,093 (1) Impact of redemption includes both shares repurchased in the open market at a premium or discount and shares redeemed at par on an eligible call date. Series D Preferred Stock During the first quarter of 2021, we redeemed all of our outstanding Series D Depositary Shares, resulting in an impact of preferred stock redemption of $3.3 million in the accompanying consolidated statements of operations. On August 23, 2019, the Company completed a tender offer for Series D Depositary Shares, resulting in the repurchase of 734,823 outstanding Series D Depositary Shares and the related retirement of 18,371 outstanding shares of Series D Preferred Stock. Series E Preferred Stock On August 23, 2019, the Company completed a tender offer for Series E Depositary Shares, resulting in the repurchase of 980,928 outstanding Series E Depositary Shares and the related retirement of 24,523 outstanding shares of Series E Preferred Stock. See Note 27 - Subsequent Events for additional detail related to the upcoming redemption of Series E Preferred Stock. Common Share Repurchase Program On February 10, 2020, we announced that our Board of Directors authorized the repurchase of up to $45 million of our common stock. This repurchase authorization expired on February 10, 2021. There were no repurchases of common shares during the year ended December 31, 2021. During the year ended December 31, 2020, we repurchased 827,584 shares of common stock at a weighted average price of $14.50 per share and an aggregate amount of $12.0 million. Purchases were authorized to be made in open-market transactions, in block transactions on or off an exchange, in privately negotiated transactions, or by other means as determined by our management and in accordance with the regulations of the Securities and Exchange Commission. The timing of purchases and the number of shares repurchased under the program depended on a variety of factors including price, trading volume, corporate and regulatory requirements, and market conditions. Change in Accumulated Other Comprehensive Income (Loss) Our AOCI includes unrealized gain (loss) on securities available-for-sale. Changes to AOCI are presented net of the tax effect as a component of stockholders' equity. Reclassifications from AOCI occur when a security is sold, called or matures and are recorded on the consolidated statements of operations either as a gain or loss.

REGULATORY CAPITAL MATTERS

REGULATORY CAPITAL MATTERS	12 Months Ended

Federal Home Loan Banks [Abstract]
REGULATORY CAPITAL MATTERS	REGULATORY CAPITAL MATTERSThe Company and the Bank are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Management believes as of December 31, 2021, the Company and the Bank met all capital adequacy requirements to which they were then subject. With respect to the Bank, prompt corrective action regulations provide five classifications: well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. Depending on the regulatory capital levels, banks are subject to limitations such as requiring regulatory approval to accept brokered deposits if an institution is only adequately capitalized or limiting capital distributions or asset growth and expansion and requiring a capital restoration plan if an institution is undercapitalized. At December 31, 2021, the most recent regulatory notification categorized the Bank as well-capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes would have changed our classification. In addition to the minimum CET1, Tier 1, total capital and leverage ratios, the Company and the Bank must maintain a capital conservation buffer consisting of additional CET1 capital greater than 2.5% of risk-weighted assets above the required minimum risk-based capital levels in order to avoid limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses.

That guidance provides that bank holding companies that plan to pay dividends that exceed net earnings for a given period should first consult with the Federal Reserve. To the extent the Company's future quarterly dividend exceeds net earnings, less prior dividends, over the applicable quarterly time periods, the payment of the Company’s common and preferred stock dividends will be subject to prior consultation and non-objection from the Federal Reserve. Our principal source of funds for dividend payments is dividends received from the Bank. Federal banking laws and regulations limit the amount of dividends that may be paid without prior approval of regulatory agencies. Under these regulations, in the case of the Bank, the amount of dividends that may be paid in any calendar year is limited to the current year’s net profits, combined with the retained net profits of the preceding two years, subject to the capital requirements described above. Accordingly, any dividend paid to us by the Bank would be limited by the need to maintain the Bank's well capitalized status plus the capital buffer in order to avoid additional dividend restrictions. As described below, any near term dividend by the Bank will require OCC approval. During the year ended December 31, 2021, the Bank received approval from the OCC and paid $78.0 million in dividends to the holding company. During the years ended December 31, 2021 and 2020, we declared and paid dividends on our common stock of $0.24 per share, representing a quarterly dividend of $0.06 per share. During the year ended December 31, 2019, we declared and paid dividends on our common stock of $0.31 per share, with the quarterly dividend ranging from $0.13 per share in the first quarter of 2019 to $0.06 per share for each of the subsequent 2019 quarters. During the years ended December 31, 2021, 2020 and

VARIABLE INTEREST ENTITIES

VARIABLE INTEREST ENTITIES	12 Months Ended
	Dec. 31, 2021
Organization, Consolidation and Presentation of Financial Statements [Abstract]
VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES We hold ownership interests in alternative energy partnerships and qualified affordable housing partnerships and have a variable interest in a multifamily securitization trust. We evaluate our interests in these entities to determine whether they meet the definition of a VIE and whether we are required to consolidate these entities. A VIE is consolidated by its primary beneficiary, which is the party that has both (i) the power to direct the activities that most significantly impact the economic performance of the VIE and (ii) a variable interest that could potentially be significant to the VIE. To determine whether or not a variable interest we hold could potentially be significant to the VIE, we consider both qualitative and quantitative factors regarding the nature, size, and form of our involvement with the VIE. We have determined that our interests in these entities meet the definition of variable interests; however none of the VIE's meet the criteria for consolidation. Unconsolidated VIEs Multifamily Securitization During the third quarter of 2019, we transferred $573.5 million of multifamily loans, through a two-step process, to a third-party depositor which placed the multifamily loans into a third-party trust (a VIE) that issued structured pass-through certificates to investors. The transfer of these loans was accounted for as a sale for financial reporting purposes, in accordance with ASC 860. We determined that we are not the primary beneficiary of this VIE as we do not have the power to direct the activities that will have the most significant economic impact on the entity. Our continuing involvement in this securitization is limited to customary obligations associated with the securitization of loans, including the obligation to cure, repurchase, or substitute loans in the event of a material breach in representations. Additionally, we have the obligation to guarantee credit losses up to 12% of the aggregate unpaid principal balances at cut-off date of the securitization. This obligation is supported by a $68.8 million letter of credit between Freddie Mac and the FHLB. The maximum loss exposure that would be absorbed by us in the event that all of the assets in the securitization trust are deemed worthless is $68.8 million, which represents the aforementioned obligation to guarantee credit losses up to 12%. We believe that the loss exposure on the multifamily securitization is reduced by both loan-to-value ratios of the underlying collateral balances and the overcollateralization that exists within the securitization trust. At December 31, 2021, we have a $2.9 million loan repurchase reserve related to this VIE. There have been no losses associated with the multifamily securitization through December 31, 2021. Alternative Energy Partnerships We invest in certain alternative energy partnerships (limited liability companies) formed to provide sustainable energy projects that are designed to generate a return primarily through the realization of federal tax credits (energy tax credits). These entities were formed to invest in newly established residential and commercial solar leases and power purchase agreements. As a result of our investments, we have the right to certain investment tax credits and tax depreciation benefits (recognized on the flow through and income statement method in accordance with ASC 740), and to a lesser extent, cash flows generated from the installed solar systems leased to individual consumers for a fixed period of time. While our interest in the alternative energy partnerships meets the definition of a VIE in accordance with ASC 810, we have determined that we are not the primary beneficiary because we do not have the power to direct the activities that most significantly impact the economic performance of the entities including operational and credit risk management activities. As we are not the primary beneficiary, we did not consolidate the entities. We use the HLBV method to account for our investments in energy tax credits as an equity investment under ASC 970-323-25-17. Under the HLBV method, an equity method investor determines its share of an investee's earnings by comparing its claim on the investee's book value at the beginning and end of the period, assuming the investee were to liquidate all assets at their U.S. GAAP amounts and distribute the resulting cash to creditors and investors under their respective priorities. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period, after adjusting for capital contributions and distributions, is our share of the earnings or losses from the equity investment for the period. To account for the tax credits earned on investments in alternative energy partnerships, we use the flow-through income statement method. Under this method, the tax credits are recognized as a reduction to income tax expense in the year the investment is made and the initial book-tax differences in the basis of the investments are recognized as additional tax expense in the year they are earned. Investments in alternative energy partnerships totaled $25.9 million and $28.0 million at December 31, 2021 and 2020. The following table presents information regarding activity in our alternative energy partnerships for the periods indicated: Year Ended December 31, ($ in thousands) 2021 2020 2019 Fundings $ — $ 3,631 $ 806 Cash distribution from investment 2,293 2,094 2,025 Gain (loss) on investments in alternative energy partnerships 204 365 (1,694) Tax expense (benefit) recognized from HLBV application 59 45 (362) Income tax credits recognized — — 3,446 The following table represents the carrying value of the associated unconsolidated assets and liabilities and the associated maximum loss exposure for alternative energy partnerships as of the dates indicated: ($ in thousands) December 31, December 31, Cash $ 4,227 $ 3,228 Equipment, net of depreciation 246,421 241,015 Other assets 9,098 7,470 Total unconsolidated assets $ 259,746 $ 251,713 Total unconsolidated liabilities $ 12,129 $ 6,357 Maximum loss exposure $ 25,888 $ 27,977 The maximum loss exposure that would be absorbed by us in the event that all of the assets in alternative energy partnerships are deemed worthless is $25.9 million, which is our recorded investment amount at December 31, 2021. We believe that the loss exposure on our investments is reduced considering our return on our investment is provided not only by the cash flows of the underlying client leases and power purchase agreements. In addition, our exposure is further limited as the arrangements include a transition manager to support any transition of the solar company sponsor, whose role includes that of the servicer and operation and maintenance provider, in the event the sponsor would be required to be removed from its responsibilities (e.g., bankruptcy, breach of contract, etc.). Capital Trusts - Trust Preferred Securities In connection with our merger with PMB, we acquired investments in two grantor trusts. These grantor trusts were originally formed to sell and issue trust preferred securities to institutional investors (Refer to Note 12 - Long-term Debt ). We are not the primary beneficiary, and consequently, these grantor trusts are not consolidated in the consolidated financial statements. At December 31, 2021, our investment in these grantor trusts, which is included in other assets in the consolidated balance sheets, totaled $527 thousand. Qualified Affordable Housing Partnerships - Low Income Housing Tax Credits We invest in limited partnerships that operate affordable housing projects that qualify for low income housing tax credits (“LIHTC”). The returns on these investments are generated primarily through allocated Federal tax credits and other tax benefits. In addition, LIHTC investments contribute to our goals under the Community Reinvestment Act. These limited partnerships are considered to be VIEs, because either (i) they do not have sufficient equity investment at risk or (ii) the limited partners with equity at risk do not have substantive kick-out rights through voting rights or substantive participating rights over the general partner. As a limited partner, we are not the primary beneficiary because the general partner has the ability to direct the activities of the VIEs that most significantly impact their economic performance. As a result, we do not consolidate these partnerships. The following table presents information regarding balances in LIHTC investments for the periods indicated: ($ in thousands) December 31, December 31, Ending balance (1) $ 38,982 $ 43,209 Aggregate funding commitment 61,278 61,278 Total amount funded 51,014 42,991 Unfunded commitment 10,264 18,287 Maximum loss exposure 38,982 43,209 (1) Included in other assets in the accompanying consolidated statements of financial condition.

Deposit Service Fees Service charges on deposit accounts consist of account analysis fees, monthly service fees, check orders, and other deposit related fees. Our performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account related fees are largely transactional based, and therefore, our performance obligation is satisfied, and related revenue recognized, at a point in time as incurred. Debit Card Fees When clients use their debit cards to pay merchants for goods or services, we retain a fee from the funds collected from the related deposit account and transfer the remaining funds to the payment network for remittance to the merchant. The performance obligation to the merchant is satisfied and the fee is recognized at the point in time when the funds are collected and transferred to the payment network. Investment Commissions We acted as an agent for a third party vendor that provides investment services and products to clients. Upon completion of a sale of investment services or products to a client, we received a commission from the third party vendor. The performance obligation to the third party vendor was satisfied and the commission income was recognized at that point in time. We stopped offering this service after July 2019. Other Other noninterest income primarily consists of other recurring revenue streams from merchant referral commissions. Our performance obligation for merchant referral commissions is satisfied with the successful sale of services to those referred merchants, which is when the commission is received and the income is recognized. Gains and Losses on Sales of OREO Net gains (losses) on sales of OREO totaling $410 thousand, $(38) thousand and $40 thousand for the years ended December 31, 2021, 2020 and 2019 are included in other non-interest expense.

Certain prior period amounts have been reclassified to conform to current period presentation . For the year ended December 31, 2020, $2.5 million in noninterest expense was reclassified from “all other expense” to “extinguishment of debt” in the accompanying consolidated statement of operations. Significant accounting policies followed by the Company are presented below.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements: The preparation of financial statements, in conformity with GAAP, requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the consolidated financial statements and disclosures provided, and actual results could differ. The ACL (which includes the ALL and the reserve for unfunded loan commitments), loan repurchase reserve, realization of deferred tax assets, the fair value of assets and liabilities acquired in business combinations and related purchase price allocation, the valuation of goodwill and other intangible assets, other derivatives, HLBV of investments in alternative energy partnerships, and the fair value measurement of financial instruments are particularly subject to change and such change could have a material effect on the consolidated financial statements.
Segment Reporting	Segment Reporting:
Variable Interest Entities (“VIE”)	Variable Interest Entities (“VIE”): We hold ownership interests in certain special purpose entities. We evaluate our interest in these entities to determine whether they meet the definition of a VIE and whether we meet the criteria as their primary beneficiary and are therefore required to consolidate these entities. A primary beneficiary of a VIE is defined as the party that has both the power to direct the activities that most significantly impact the VIE and a variable interest that could be significant to the VIE. A variable interest is a contractual ownership or other interest that changes with changes in the fair value of the VIE’s net assets. To determine whether or not a variable interest we hold could be significant to the VIE, we consider both qualitative and quantitative factors regarding the nature, size and form of our involvement with the VIE. We continually analyze whether we are the primary beneficiary of a VIE. Changes in facts and circumstances occurring since the previous primary beneficiary determination are considered as part of this ongoing assessment.
Cash and Cash Equivalents	Cash and Cash Equivalents: Cash and cash equivalents include cash on hand, cash items in transit, cash due from the Federal Reserve Bank and other financial institutions, and federal funds sold with original maturities less than 90 days. Banking regulations previously required that banks maintain a percentage of their deposits as reserves in cash or on deposit with the Federal Reserve Bank. On March 15, 2020, the FRB announced that it had reduced reserve requirement ratios to 0 percent effective on March 26, 2020, which represented the beginning of the next reserve maintenance period. The FRB took this action in light of the Federal Open Market Committee's announcement in 2019 that it intends to implement monetary policy in an ample reserves regime, where reserve requirements do not play a role. The FRB's action is intended to help support lending to households and businesses
Available-for-Sale Debt Securities	Available-for-Sale Debt Securities: Available-for-sale debt securities are carried at fair value. Accreted discounts and amortized premiums are included in interest income using the interest method, and realized gains or losses from sales of securities are calculated using the specific identification method.
Loans Held for Sale, Carried at Fair Value	Loans Held-For-Sale, Carried at Fair Value: Loans held-for-sale, carried at fair value, are generally conforming SFR mortgage loans that are originated and intended for sale in the secondary market, repurchased loans that were previously sold to GNMA and other GSEs, and loans sold to GNMA that are delinquent more than 90 days and subject to a unilateral purchase option by us. The fair value of loans held-for-sale is based on commitments outstanding from investors as well as what secondary market investors are currently offering for portfolios with similar characteristics. Interest income on loans held-for-sale under the fair value option is measured based on the contractual interest rate and reported in interest income on loans, including fees in the consolidated statements of operations.
Loans and Acquired Loans	Loans: When a determination is made at the time of commitment to originate or purchase loans as held-for-investment, it is our intent to hold these loans to maturity or for the foreseeable future, subject to periodic review under our management evaluation processes, including asset/liability management . Loans, excluding purchased credit deteriorated (“PCD”) loans, that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, are recorded at the principal balance outstanding, net of charge-offs, unamortized purchase premiums and discounts, and deferred loan fees and costs. Amortization of deferred loan origination fees and costs or purchase premiums and discounts are recognized in interest income as an adjustment to yield over the terms of loans using the interest method. Deferred loan origination fees and costs on revolving lines of credit are amortized using the straight-line method. Interest on loans is credited to interest income as earned based on the interest rate applied to principal amounts outstanding. Interest income is accrued on the unpaid principal balance and is discontinued when management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that full collection of principal or interest becomes doubtful, regardless of the length of past due status. Generally, loans are placed on nonaccrual status when scheduled payments become past due for 90 days or more. When accrual of interest is discontinued, any unpaid accrued interest receivable is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. A charge-off is generally recorded at 180 days past due for SFR mortgage loans if the unpaid principal balance exceeds the fair value of the collateral less costs to sell. Commercial and industrial and commercial real estate loans financings are subject to a detailed review when 90 days past due to determine accrual status, or when payment is uncertain and a specific consideration is made to put a loan on nonaccrual status. A charge-off for commercial and industrial and commercial real estate loans is recorded when a loss is confirmed. Consumer loans, other than those secured by real estate, are typically charged off no later than 120 days past due. Acquired Loans : At acquisition date, loans are evaluated to determine whether they meet the criteria of a PCD loan. PCD loans are loans that in management's judgment have experienced more than insignificant deterioration in credit quality since origination. Factors that indicate a loan may have experienced more than insignificant credit deterioration include delinquency, downgrades in credit rating, non-accrual status, and other negative factors identified by management at the time of initial assessment. PCD loans are initially recorded at fair value, with the resulting non-credit discount or premium being amortized or accreted into interest income using the interest method. In addition to the fair value adjustment, at the date of acquisition, an allowance for credit losses (“ACL”) is established with a corresponding increase to the overall acquired loan balance. This initial ACL is determined using the Company's current expected credit losses methodology. Acquired loans that are not considered PCD loans (“non-PCD loans”) are recognized at fair value at the acquisition date, with the resulting credit and non-credit discount or premium being amortized or accreted into interest income using the interest method. In addition to the fair value adjustment, at the time of acquisition, the Company establishes an initial ACL through a charge to the provision for credit losses. This initial ACL is determined using the Company's current expected credit losses methodology. Subsequent to acquisition date, the allowance for credit losses for both PCD and non-PCD loans is determined using the same methodology to determine current expected credit losses that is applied to all other loans.
Allowance for Credit Losses and Reserve for Unfunded Loan Commitments	Allowance for Credit Losses: The ACL is estimated on a quarterly basis and represents management’s estimate of current expected credit losses in the Company's loan portfolio. Pools of loans with similar risk characteristics are collectively evaluated while loans that no longer share risk characteristics with loan pools are evaluated individually. The ACL is established through the provision for credit loss expense. Loans deemed uncollectible are charged off and deducted from the allowance. Recoveries on loans previously charged off are added to the allowance. The ACL process involves subjective and complex judgments. Credit losses are not estimated for accrued interest receivable as interest that is deemed uncollectible is written off through interest income. Collective loss estimates are determined by applying loss factors, designed to estimate current expected credit losses, to amortized cost balances over the remaining life of the collectively evaluated portfolio. Loans with similar risk characteristics are aggregated into homogeneous pools. The ACL consists of: (i) a specific allowance established for current expected credit losses on loans individually evaluated, (ii) a quantitative allowance for current expected loan losses based on the portfolio and expected economic conditions over a reasonable and supportable forecast period that reverts back to long-term trends to cover the expected life of the loan; and (iii) a qualitative allowance including management overlays to capture factors and trends that are not adequately reflected in the quantitative allowance, including an evaluation of our underwriting, other credit-related processes, and other credit risk factors such as concentration risk. The need for a loan to be individually evaluated, based on current information and events, is when it no longer meets the risk characteristics of the similarly identified pool of financial assets to be collectively evaluated. We measure expected credit losses on all individually evaluated loans under the guidance of ASC 326, Receivables , primarily through the evaluation of collateral values and estimated cash flows expected to be collected. Cash receipts on individually evaluated loans for which the accrual of interest has been discontinued are applied first to principal and then to interest income. Prior to the adoption of ASC 326, individually evaluated loans were referred to as impaired loans. Expected credit losses are estimated over the contractual term of the loans, adjusted for estimated prepayments, as appropriate. The contractual term excludes expected extensions and renewals unless those extension or renewal options are included in the underlying contract and we do not have the ability to unconditionally cancel. The contractual term also excludes expected modifications unless management has a reasonable expectation, at the reporting period, that a troubled debt restructuring will be executed. The allowance for loan losses includes qualitative adjustments to bring the allowance to the level management believes is appropriate based on factors that have not otherwise been fully accounted for, including those described in the federal banking agencies' joint interagency policy statement on ALL. These factors include, among others, inherent imprecision in forecasting economic variables, including determining the depth and duration of economic cycles and their impact to relevant economic variables; qualitative adjustments based on our evaluation of different forecast scenarios and known recent events impacting relevant economic variables; data factors that address the risk that certain model inputs may not reflect all available information including (i) risk factors that have not been fully addressed in internal risk ratings, (ii) changes in lending policies and procedures, (iii) changes in the level and quality of experience held by lending management, (iv) imprecision in the risk rating system and (v) limitations in data available for certain loan portfolios. The ACL process also includes challenging and calibrating the model and model results against observed information, trends and events within the loan portfolio, among others. Prior to the adoption of ASC 326, we maintained an allowance for loan losses to absorb probable incurred losses inherent in the loan portfolio at the balance sheet date. The allowance for loan losses was based on ongoing assessment of the estimated probable losses presently inherent in the loan portfolio. In evaluating the level of the allowance for loan losses, management considered the types of loans and the amount of loans in the portfolio, peer group information, historical loss experience, adverse situations that may have affected the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. We have established credit risk management processes that include regular management review of the loan portfolio to identify problem loans. During the ordinary course of business, management may become aware of borrowers who may not be able to fulfill their contractual payment requirements within the loan agreements. Such loans are subject to increased monitoring. Consideration is given to placing these loans on nonaccrual status, assessing the need for additional allowance for credit loss, and partially or fully charging off the principal balance. The credit risk monitoring system is designed to identify loans with credit deterioration and potential problem loans, perform periodic evaluation of impairment, and determine the adequacy of the allowance for credit losses in a timely manner. In addition, management has adopted a credit policy that includes a credit review and control system that it believes should be effective in ensuring that we maintain an adequate ACL. Further, the Board of Directors provides oversight and guidance for the ACL process. At December 31, 2021, the following loan portfolio segments have been identified: • Commercial and industrial (general commercial and industrial, warehouse lending, and indirect/direct leveraged lending) • Commercial real estate • Multifamily • Small Business Administration (“SBA”) • Construction • SFR - 1st deeds of trust (generally SFR mortgage and other) • Other consumer (automotive and HELOC) We categorize loans into risk categories based on relevant information about the ability of borrowers to service their obligations such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. We analyze loans individually by classifying the loans as to credit risk. Loans secured by multifamily and commercial real estate properties generally involve a greater degree of credit risk. Because payments on loans secured by multifamily and commercial real estate properties are often dependent on the successful operation or management of the properties, repayment of these loans may be subject to adverse conditions in the real estate market or the economy. In addition, commercial and industrial loans are also considered to have a greater degree of credit risk due to the fact that commercial and industrial loans are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment of commercial and industrial loans may be substantially dependent on the success of the business itself (which, in turn, is often dependent, in part, upon general economic conditions). Within the commercial and industrial portfolio, warehouse credit facilities are considered to have a lesser degree of risk then other commercial and industrial loans. Warehouse credit facilities are secured by newly granted single family residential mortgages underwritten with current borrower financial information. SBA loans are similar to commercial and industrial loans, however, they have additional credit enhancement in the form of a guaranty provided by the U.S. Small Business Administration, for up to 85% of the loan amount for loans up to $150 thousand and 75% of the loan amount for loans of more than $150 thousand. We often sell the guaranteed portion of certain SBA loans into the secondary market. The availability of funds for the repayment of financing may be substantially dependent on the success of the business itself which is often dependent, in part, upon general economic conditions. Included in SBA loans are the loans originated as part of the PPP established by the CARES Act, which have additional credit enhancement provided by the U.S. Small Business Administration for up to 100% of the loan amount. As of December 31, 2021, PPP loans totaled $123.1 million, net of $772 thousand in unamortized fees which are being amortized over their estimated life. The Company estimated the average life of our PPP loans to be 12 months to 18 months based on our understanding of our clients' cash use, expected forgiveness probability, and loan forgiveness process. Consumer loans have credit risk given that collection of these loans is dependent on the borrower’s continuing financial stability and, thus, are more likely to be adversely affected by job loss, divorce, illness, or personal bankruptcy. Green Loans are SFR first and second mortgages lines of credit with a linked checking account that allows all types of deposits and withdrawals to be performed. Green Loans are considered to carry a higher degree of credit risk than the general SFR portfolio due to their unique cash flows. Credit risk on this asset class is also managed through the completion of regular third party AVMs of the underlying collateral and monitoring of the borrower’s usage of this account to determine if the borrower is making monthly payments from external sources or “drawdowns” on their line. In cases where the property values have declined to levels less than the original LTV ratios, or other levels deemed prudent by us, we may curtail the line and/or require monthly payments or principal reductions to bring the loan in balance. On interest only loans, we project future payment changes to determine if there will be a material increase in the required payment and then monitor the loans for possible delinquency. Individual loans are monitored for possible downgrading of risk rating. Reserve for Unfunded Loan Commitments: The reserve for unfunded loan commitments provides for current estimated credit losses for the unused portion of collective pools of lending commitments expected to be funded, except for unconditionally cancellable commitments for which no reserve is required under ASC 326. The reserve for unfunded loan commitments includes reserve factors that are consistent with the ACL methodology for loans using the expected loss factors and an estimated utilization or probability of draw factor, which are based on historical experience. Changes in the reserve for unfunded loan commitments are reported as a component of provision for credit losses in the consolidated statements of operations and the reserve for unfunded loan commitments is included in accrued expenses and other liabilities in the consolidated statements of financial condition.
Troubled Debt Restructurings	Troubled Debt Restructurings: A loan is identified as a TDR when a borrower is experiencing financial difficulties and, for economic or legal reasons related to these difficulties, we grant a concession (or we reasonably expect to grant a concession) to the borrower in the restructuring that we would not otherwise consider. We have granted a concession when, as a result of the restructuring to a troubled borrower, we do not expect to collect all amounts due, including principal and/or interest accrued at the original terms of the loan. The concessions may be granted in various forms, including a below-market change in the stated interest rate, a reduction in the loan balance or accrued interest, an extension of the maturity date, or a note split with principal forgiveness. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under our internal underwriting policy. Loans for which the borrower has been discharged under Chapter 7 bankruptcy are considered collateral dependent TDRs, and charged down to the fair value of collateral less cost to sell. A restructuring executed at an interest rate that is at market interest rates based on the current credit characteristics of the borrower is not a TDR. Our policy is to place consumer loan TDRs, except those that were performing prior to TDR status, on nonaccrual status for a minimum period of 6 months. Commercial TDRs are evaluated on a case-by-case basis for determination of whether or not to place them on nonaccrual status. Loans qualify for return to accrual status once they have demonstrated performance under the restructured terms of the loan for a minimum of 6 months. Generally, TDRs are reported as TDRs for the remaining life of the loan. TDR classification may be removed if the borrower demonstrates compliance with the modified terms for a minimum of 6 months, through one fiscal year-end and the restructuring agreement specifies a market rate of interest equal to that which would be provided to a borrower with similar credit at the time of restructuring. In the limited circumstance that a loan is removed from TDR classification, it is our policy to continue to base our measure of loan impairment on the contractual terms specified by the loan agreement. TDR Relief: In order to encourage banks to work with impacted borrowers, the CARES Act and U.S. banking regulatory agencies have provided relief from TDR accounting on loans which qualify under the relevant provisions of the CARES Act or the “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus” on March 22, 2020 and revised April 7, 2020. The main provisions of TDR relief include 1) a capital provision in the form of reduced risk-weighted assets, as TDRs are more heavily risk-weighted for capital purposes; 2) a delinquency status provision, as the aging of loans are frozen, i.e., they will continue to be reported in the same delinquency status they were in at the time of modification; and 3) a nonaccrual status provision as the loans are generally not reported as nonaccrual or TDRs during the modification period.
Fair Value of Financial Instruments	Fair Values of Financial Instruments: We measure certain assets and liabilities on a fair value basis, in accordance with ASC Topic 820, "Fair Value Measurement." Fair value is used on a recurring basis for certain assets and liabilities in which fair value is the primary basis of accounting. Examples of these include derivative instruments and available-for-sale securities. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment in accordance with ASC Topic 825, "Financial Instruments." Examples of these include loans individually evaluated for credit losses, long-lived assets, OREO, goodwill, and core deposit intangible assets as well as loans held-for-sale accounted for at the lower of cost or fair value. Fair value is the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants. When observable market prices are not available, fair value is estimated using modeling techniques such as discounted cash flow analysis. These modeling techniques utilize assumptions that market participants would use in pricing the asset or the liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset, and the risk of nonperformance. Depending on the nature of the asset or liability, we use various valuation techniques and assumptions when estimating the instrument’s fair value. Considerable judgment may be involved in determining the amount that is most representative of fair value.
Federal Home Loan Bank and Federal Reserve Bank Stock	Federal Home Loan Bank and Federal Reserve Bank Stock: The Bank is a member of the FHLB and FRB system. Members are required to own a certain amount of FHLB and FRB stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB and FRB stock are 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 on the consolidated statements of operations under interest and dividend income from other interest-earning assets.
Other Real Estate Owned (“OREO")	Other Real Estate Owned (“OREO"): OREO, which represents real estate acquired through foreclosure in satisfaction of commercial and real estate loans, is initially recorded at fair value less estimated selling costs of the real estate, based on current independent appraisals obtained at the time of acquisition, less costs to sell when acquired, establishing a new cost basis. Loan balances in excess of fair value of the real estate acquired at the date of acquisition are charged off against the ACL. A valuation allowance is established for any subsequent declines in fair value less estimated selling costs and adjusted as applicable. Gains and losses on the sale of OREO and reductions in fair value subsequent to foreclosure, and any subsequent operating expenses or income of such properties are included in all other expense on the consolidated statements of operations.
Premises, Equipment	Premises and Equipment: Land is carried at cost. Premises and equipment are recorded at cost less accumulated depreciation. The straight-line method is used for depreciation with the following estimated useful lives: building - 40 years and leasehold improvements - shorter of useful life or life of lease, and furniture, fixtures, and equipment - 3 to 7 years. Maintenance and repairs are expensed as incurred and improvements that extend the useful lives of assets are capitalized.
Long-term Assets	Premises and equipment are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value, less selling costs. For impairment purposes, fair value is determined utilizing market values of similar assets or replacement cost as applicable.
Bank Owned Life Insurance	Bank Owned Life Insurance: The Bank has purchased life insurance policies on certain key employees. BOLI is recorded at the amount that can be realized under the insurance contract, which is the cash surrender value.
Leases	Leases: Leases are accounted for in accordance with ASC 842 - Leases.
Business Combinations	Business Combinations: Business combinations are accounted for using the acquisition method of accounting under ASC Topic 805 - Business Combinations . Under the acquisition method, the Company measures the identifiable assets acquired, including identifiable intangible assets, and liabilities assumed in a business combination at fair value on acquisition date. Goodwill is generally determined as the excess of the fair value of the consideration transferred, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Merger-related costs, which may include advisory, legal, accounting, valuation, other professional or consulting fees, conversion, employee severance and change in control costs, and facilities-related charges are expensed in the periods in which the costs are incurred and the services are received.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets: Goodwill represents the excess purchase price of businesses acquired over the fair value of the identifiable net assets acquired and is assigned to specific reporting units. Goodwill is not subject to amortization and is evaluated for impairment at least annually, normally during the fourth fiscal quarter, or more frequently in the interim if events occur or circumstances change indicating it would more likely than not result in a reduction of the fair value of a reporting unit below its carrying value. During the fourth quarter of 2020, the Company voluntarily changed the date of its annual goodwill impairment test from August 31st to October 1st. We conducted our annual impairment test as of August 31, 2020 and again as of October 1, 2020 for this transition and concluded that there was no impairment as of those dates. This voluntary change is preferable under the circumstances as it better aligns with the Company’s annual operating and strategic planning processes. This voluntary change in accounting principle which is related to the annual testing date will not delay, accelerate or avoid an impairment charge. This change was not applied retrospectively as it is impracticable to do so because retrospective application would require application of significant estimates and assumptions with the use of hindsight. Accordingly, the change was applied prospectively. Goodwill is evaluated for impairment by either performing a qualitative evaluation or a quantitative test. The qualitative evaluation is an assessment of factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If it is more likely than not that the fair value of a reporting unit is below its carrying value, we perform a quantitative test whereby the fair value of a reporting unit is compared to its carrying amount, including goodwill. We determine the estimated fair value of each reporting unit using a discounted cash flow analysis and comparable public company market values. Discounted cash flow estimates include significant management assumptions relating to revenue growth rates, net interest margins, weighted-average cost of capital, and future economic and market conditions. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired. Otherwise, if a reporting unit's carrying value exceeds fair value, the difference is charged to noninterest expense. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights, or because the asset is capable of being sold or exchanged either separately or in combination with a related contract, asset or liability. Other intangible assets, such as Core Deposit Intangibles ("CDI"), with finite useful lives are amortized to noninterest expense over their estimated useful lives and are evaluated for impairment whenever events occur or circumstances change indicating the carrying amount of the asset may not be recoverable.
Alternative Energy Partnerships	Alternative Energy Partnerships: We invest in certain alternative energy partnerships (limited liability companies) formed to provide sustainable energy projects that are designed to generate a return primarily through the realization of federal tax credits (energy tax credits) and other tax credits. We are a limited partner in these partnerships, which were formed to invest in newly installed residential and commercial solar leases and power purchase agreements. As our respective investments in these entities are more than minor, we have significant influence, but not control, over the investee’s activities that most significantly impact its economic performance. As a result, we are required to apply the equity method of accounting, which generally prescribes applying the percentage ownership interest to the investee’s GAAP net income in order to determine the investor’s earnings or losses in a given period. However, because the liquidation rights, tax credit allocations and other benefits to investors can change upon the occurrence of specified events, application of the equity method based on the underlying ownership percentages would not accurately represent our investment. As a result, we apply the HLBV method of the equity method of accounting. The HLBV method is a balance sheet approach where a calculation is prepared at each balance sheet date to estimate the amount that we would receive if the equity investment entity were to liquidate all of its assets (as valued in accordance with GAAP) and distribute that cash to the investors based on the contractually defined liquidation priorities. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period, after adjusting for capital contributions and distributions, is our share of the earnings or losses from the equity investment for the period. To account for the tax credits earned on investments in alternative energy partnerships, we use the flow-through income statement method. Under this method, the tax credits are recognized as a reduction to income tax expense and the initial book-tax differences in the basis of the investments are recognized as additional tax expense in the year they are earned.
Affordable Housing Fund Investment	Affordable Housing Fund Investment: We have invested in limited partnerships that were formed to develop and operate several apartment complexes designed as high-quality affordable housing for lower income tenants throughout the State of California and other states. We account for these investments under the proportional amortization method. Our ownership in each limited partnership varies from 4.4% to 26.2%. Each of the partnerships must meet the regulatory minimum requirements for affordable housing for a minimum 15-year compliance period to fully utilize the tax credits. If the partnerships cease to qualify during the compliance period, the credit may be denied for any period in which the project is not in compliance and a portion of the credit previously taken is subject to recapture with interest. Investments accounted for under the proportional amortization method are required to be tested for impairment when events or changes in circumstances indicate that it is more-likely-than-not that the carrying amount of the investment will not be realized. Impairment is measured as the difference between the investment’s carrying amount and its fair value and would be recorded in other noninterest expense in the consolidated statements of operations.
Loan Repurchase Reserve	Loan Repurchase Reserve: We maintain a reserve for expected losses on loans that were sold and are no longer on our balance sheet for loans we might be required to repurchase (or the indemnity payments we may have to make to purchasers) which we refer to as the loan repurchase reserve. When we sell loans into the secondary mortgage market, we make customary representations and warranties to the purchasers about various characteristics of each loan, such as the manner of origination, the nature and extent of underwriting standards applied and the types of documentation being provided. Typically, these representations and warranties are in place for the life of the loan. If a defect in the origination process is identified, we may be required to either repurchase the loan or indemnify the purchaser for losses it sustains on the loan. If there are no such defects, generally we have no liability to the purchaser for losses it may incur on such loan. The reserve takes into account both the estimate of expected losses on loans sold during the current accounting period, as well as adjustments to the previous estimates of expected losses on loans sold. In each case, these estimates are based on the most recent data available, including data from third parties, regarding demand for loan repurchases, actual loan repurchases, and actual credit losses on repurchased loans, among other factors.
Deferred Financing Costs	Deferred Financing Costs: Deferred financing costs associated with our senior not
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments: Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet client financing needs. The face amount for these items represents the exposure to loss, before considering client collateral or ability to repay. Such financial instruments are recorded as loans when they are funded.
Stock-Based Compensation	Stock-Based Compensation: Compensation cost is recognized for stock options, restricted stock awards and units, and stock appreciation rights 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 and stock appreciation rights, while the market price of our voting common stock at the date of grant is used for restricted stock awards and units. Generally, compensation cost is recognized over the required service period, defined as meeting performance goals and the vesting period. For awards with
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 are computed for differences between the financial statement and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Deferred tax assets are also recognized for operating loss and tax credit carryforwards. Accounting guidance requires that companies assess whether a valuation allowance should be established against the deferred tax assets based on the consideration of all available evidence using a “more likely than not” standard. 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, We and our subsidiaries are subject to U.S. Federal incom e tax as well as income tax in multiple state jurisdictions. We are no longer subject to examination by U.S. Federal taxing authorities for years before 2018. The statute of limitations for the assessment of California Franchise taxes has expired for tax years before 2017; other state in come and franchise tax statutes of limitations vary by state. Tax positions that are uncertain but meet a more-likely-than-not recognition threshold are initially and subsequently measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position meets the more likely than not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management's judgment. We reclassify stranded tax effects from accumulated other comprehensive income to retained earnings in periods in which there is a change in corporate income tax rates.
Earnings (Loss) Per Common Share	Earnings (Loss) Per Common Share: Earnings (loss) per common share is computed under the two-class method. Basic EPS is computed by dividing net income (loss) allocated to common stockholders by the weighted-average number of shares outstanding. Diluted EPS is computed by dividing net income (loss) allocated to common stockholders by the weighted-average number of shares outstanding, adjusted for the dilutive effect of the restricted stock units and outstanding stock options. Net income (loss) allocated to common stockholders is computed by subtracting income (loss) allocated to participating securities, participating securities dividends, preferred stock dividend and preferred stock redemption from net income. Participating securities are instruments granted in stock-based payment transactions that contain rights to receive non-forfeitable dividends or dividend equivalents, which includes the SARs to the extent they confer dividend equivalent rights.
Comprehensive Income	Comprehensive Income: Comprehensive income consists of net income and other comprehensive income or loss. Other comprehensive income or loss includes unrealized gains and losses on securities available-for-sale, net of tax, which are recognized as a separate component of stockholders’ equity.
Derivative Instruments	Derivative Instruments: We record our derivative instruments at fair value as either assets or liabilities on the consolidated statements of financial condition in other assets and accrued expenses and other liabilities, respectively, and have elected to present all derivatives with counterparties on a gross basis. For fair value derivatives that qualify for hedge accounting, we record changes in the fair value in other income. For derivatives that do not qualify for hedge accounting, the fair value impact is recorded in other income in the income statement. Interest Rate Swaps and Caps. We offer interest rate swap and cap products to certain loan clients to allow them to hedge the risk of rising interest rates on their variable rate loans. When such products are issued, we also enter into an offsetting swap with institutional counterparties to eliminate the interest rate risk. These back-to-back derivative agreements, which generate fee income for us, are intended to offset each other. We retain the credit risk of the original loan. The net cash flow for us is equal to the interest income received from a variable rate loan originated with the client plus a fee. These swaps and caps are not designated as accounting hedges and are recorded at fair value in other assets and accrued expenses and other liabilities in the consolidated statements of financial condition. The changes in fair value are recorded in other income in the consolidated statements of operations. Interest Rate Swaps and Caps on Mortgage-backed Securities: During the third quarter of 2019, we partially hedged the fair value of the MBS portfolio using interest rate swaps. At the end of the third quarter of 2019, we took advantage of the decline in long term interest rates and sold the majority of the MBS portfolio and unwound the majority of the interest rate swaps. The remaining balance of the MBS portfolio and the related interest rate swap were sold and unwound in the fourth quarter 2019. The unsold portion of the MBS portfolio was deemed other–than–temporarily impaired and, along with the fair value adjustment on the swap, was recorded as a loss in noninterest income with a net impact of $731 thousand for the year ended December 31, 2019 and was included in the carrying value of MBS. Foreign Exchange Contracts . We offer short-term foreign exchange contracts to our clients to purchase and/or sell foreign currencies at set rates in the future. These products allow clients to hedge the foreign exchange rate risk of their deposits and loans denominated in foreign currencies. In conjunction with these products we also enter into offsetting contracts with institutional counterparties to hedge our foreign exchange rate risk. These back-to-back contracts allow us to offer our clients foreign exchange products while minimizing our exposure to foreign exchange rate fluctuations. These foreign exchange contracts are not designated as hedging instruments and are recorded at fair value in other assets and accrued expenses and other liabilities on the consolidated statements of financial condition.
Transfer of Financial Assets	Transfer of Financial Assets: Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is generally considered to have been surrendered when (i) the transferred assets are legally isolated from us or our consolidated affiliates, even in bankruptcy or other receivership, (ii) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee or provide more than a trivial benefit to us, and (iii) we do not maintain an obligation or the unilateral ability to reclaim or repurchase the assets. We have sold financial assets in the normal course of business, the majority of which are residential mortgage loan sales primarily to GSEs through our mortgage banking activities and other individual or portfolio loans and securities sales. In accordance with accounting guidance for asset transfers, we consider any ongoing involvement with transferred assets in determining whether the assets can be derecognized from the balance sheet. With the exception of servicing and certain performance-based guarantees, our continuing involvement with financial assets sold is minimal and generally limited to market customary representation and warranty clauses. When we sell financial assets, we may retain servicing rights and/or other interests in the financial assets. The gain or loss on sale depends on the previous carrying amount of the transferred financial assets and the fair value of the consideration received, including cash, originated mortgage servicing rights and other interests in the sold assets, and any liabilities incurred in exchange for the transferred assets. Upon transfer, any servicing assets and other interests retained by us are carried at fair value or the lower of cost or fair value.
Loss Contingencies	Loss Contingencies: Loss contingencies, including claims and legal actions, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are any such matters that will have a material effect on the consolidated financial statements that are not currently accrued for.
Dividend Restriction	Dividend Restriction: Banking regulations require maintaining certain capital levels and may limit the dividends paid by the Bank to us or by us to our stockholders.
Fee Revenue	Fee Revenue: Generally, fee revenue from deposit service charges and loans is recognized when earned, except where collection is uncertain, in which case revenue is recognized when received. We account for fee revenue in accordance with ASC Topic 606 Revenue Recognition
Advertising Costs	Advertising Costs: Advertising costs are expensed as incurred.
Adopted Accounting Pronouncements and Recent Accounting Guidance Not Yet Effective	Adopted Accounting Pronouncements: On January 1, 2020, we adopted ASU 2016-13, Financial Instruments-Credit Losses (Topic 326) (“ASU 2016-13”), which replaces the incurred loss impairment methodology with a methodology that reflects CECL and requires consideration of a broader range of reasonable and supportable information to estimate expected credit losses. The measurement of expected credit losses under the CECL model is applicable to financial assets measured at amortized cost, including loan receivables, held-to-maturity debt securities and off-balance sheet credit exposures. ASU 2016-13 also requires credit losses relating to AFS debt securities to be recorded through an allowance for credit losses. In addition, ASU 2016-13 modifies the OTTI model for AFS debt securities to require an allowance for credit impairment instead of a direct write-down, which allows for reversal of credit impairments in future periods based on improvements in credit quality. We adopted ASU 2016-13 using the modified retrospective method for our financial assets measured at cost, including loans receivable and off-balance sheet credit exposures. Results for reporting periods beginning January 1, 2020 are reported under ASU 2016-13 (or Accounting Standards Codification 326), while prior period results continue to be reported under the previously applicable GAAP. The adoption of ASU 2016-13 on January 1, 2020 resulted in an increase of $6.4 million to our allowance for credit losses and an after-tax net decrease in retained earnings of $4.5 million . This transition adjustment reflects the results of our models in estimating lifetime expected credit losses on our loans, unfunded commitments, and other off-balance sheet credit exposure primarily using a lifetime loss methodology. In February 2019, the U.S. federal bank regulatory agencies approved a final rule modifying their regulatory capital rules and providing an option to phase in over a three-year period the Day 1 adverse regulatory capital effects of ASU 2016-13. Additionally, in March 2020, the U.S. federal bank regulatory agencies issued an interim final rule that provides banking organizations an option to delay the estimated CECL impact on regulatory capital for an additional two years for a total transition period of up to five years to provide regulatory relief to banking organizations to better focus on supporting lending to creditworthy households and businesses in light of recent strains on the U.S. economy as a result of the COVID-19 pandemic. The final rule was adopted and became effective in September 2020. As a result, entities have the option to gradually phase in the full effect of CECL on regulatory capital over a five-year transition period. We implemented our CECL model commencing January 1, 2020 and elected to phase in the full effect of CECL on regulatory capital over the five-year transition period. The following table presents the impact of adopting ASU 2016-13 on January 1, 2020: ($ in thousands) As Reported Pre- Impact of Assets: Allowance for credit losses - loans Commercial: Commercial and industrial $ 23,015 $ 22,353 $ 662 Commercial real estate 10,788 5,941 4,847 Multifamily 13,214 11,405 1,809 SBA 3,508 3,120 388 Construction 4,009 3,906 103 Consumer: Single family residential mortgage 10,066 10,486 (420) Other consumer 658 438 220 Total 65,258 57,649 7,609 Liabilities: Allowance for credit losses - unfunded loan commitments $ 2,838 $ 4,064 $ (1,226) In August 2021, the FASB issued ASU 2021-06, Presentation of Financial Statements (Topic 205), Financial Services—Depository and Lending (Topic 942), and Financial Services— Investment Companies (Topic 946), Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33-10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants("ASU 2021-06") . This ASU incorporates recent SEC rule changes into the FASB Codification, including SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses , and No. 33-10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants Disclosures for Bank and Savings and Loan Registrants . The amendments in this update were effective upon addition to the FASB Codification and did not have a material impact on the consolidated financial statements. Recent Accounting Guidance Not Yet Effective Beginning in June 2023, the London Interbank Offered Rate (“LIBOR”) will be discontinued. To assist entities with the transition away from LIBOR, the Financial Accounting Standards Board (“FASB”) has issued accounting guidance to clarify GAAP and provide practical expedients for entities to utilize during the time of transition. We are in the process of evaluating the potential impact the discontinuation of LIBOR will have on our consolidated financial statements. The optional expedients and exceptions provided through this relief are set forth below and were effective immediately; however, certain provisions from this relief are not yet determined due to the fact that LIBOR has not yet been discontinued. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) , (“ASU 2020-04”) which provided optional guidance, for a limited period of time, to ease the potential burden in accounting for (or recognizing the benefits of) reference rate reform on financial reporting. The amendments in ASU 2020-04 were elective and applied to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. ASU 2020-04 provided optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria. When elected, the optional expedients for contract modifications must be applied consistently for all eligible contracts or eligible transactions within the relevant topic or industry subtopic within the codification that contains the guidance that otherwise would be required to be applied. The amendments in ASU 2020-04 were effective for all entities as of March 12, 2020 and may be applied prospectively to contract modifications made on or before December 31, 2022. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848) (“ASU 2021-01”). The amendments in ASU 2021-01 clarified that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. Specifically, certain provisions in Topic 848, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. Amendments in this Update to the expedients and exceptions in Topic 848 capture the incremental consequences of the scope clarification and tailor the existing guidance to derivative instruments affected by the discounting transition. The amendments in ASU 2021-01 are elective and apply to all entities that have derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. The amendments also optionally apply to all entities that designate receive-variable-rate, pay-variable-rate cross-currency interest rate swaps as hedging instruments in net investment hedges that are modified as a result of reference rate reform. The amendments in ASU 2021-01 were effective immediately for all entities. ASU 2021-01 is not expected to have a material effect on our consolidated financial statements.
