Banc of California, Inc. is subject to regulation by the Board of Governors of the Federal Reserve System (“FRB”) and its wholly-owned subsidiary, Banc of California, National Association (the “Bank”), operates under a national bank charter issued by the Office of the Comptroller of the Currency (“OCC”), the Bank's primary regulator. The Bank is a member of the Federal Home Loan Bank (“FHLB”) system, and maintains insurance on deposit accounts with the Federal Deposit Insurance Corporation (“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 31 full-service branches located throughout Southern California as of September 30, 2020. Basis of Presentation: The accompanying unaudited interim consolidated financial statements have been prepared pursuant to Article 10 of SEC Regulation S-X and other SEC rules and regulations for reporting on the Quarterly Report on Form 10-Q. Accordingly, certain disclosures required by U.S. generally accepted accounting principles (“GAAP”) are not included herein. These interim statements should be read in conjunction with the consolidated financial statements and notes included in the Annual Report on Form 10-K for the year ended December 31, 2019 filed by us with the SEC. The December 31, 2019 consolidated statements of financial condition presented herein has been derived from the audited financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC. Certain prior period amounts have been reclassified to conform to current period presentation, including i) reclassification of the provision for losses on unfunded loan commitments from being included in other noninterest expense to being included within provision for credit losses, ii) showing the unrealized fair value adjustment for loans held-for-sale separate from the realized net (loss) gain on sale of loans, and iii) reclassification of outside services expense from "outside services fees" to "all other expense" in the consolidated statements of operations. In the opinion of management of the Company, the accompanying unaudited interim consolidated financial statements reflect all of the adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial condition and consolidated results of operations as of the dates and for the periods presented. The results of operations for the three and nine months ended September 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. Principles of Consolidation: The accompanying unaudited consolidated financial statements include the accounts of the Company and its consolidated subsidiaries as of September 30, 2020 and December 31, 2019 and for the three and nine months ended September 30, 2020 and 2019. Significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its then wholly-owned subsidiaries. Adopted Accounting Pronouncements: On January 1, 2020, we adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326) (“ASU 2016-13”), which replaces the incurred loss impairment methodology with a methodology that reflects current expected credit losses (“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 available-for-sale (“AFS”) debt securities to be recorded through an allowance for credit losses. In addition, ASU 2016-13 modifies the other-than-temporary impairment (“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 . This transition adjustment reflects the development of our models to estimate lifetime expected credit losses on our loans, unfunded commitments, and other off-balance sheet credit exposure primarily using a lifetime loss methodology. 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) Significant Accounting Policies: The accounting and reporting policies of the Company are based upon GAAP and conform to predominant practices within the banking industry. We have not made any significant changes in our critical accounting policies from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC, except for the accounting for loans and the allowance for credit losses, the allowance for credit losses on unfunded loan commitments, troubled debt restructurings, and available-for-sale debt securities as described below. Allowance for Credit Losses (ACL): The ACL is a reserve established through a provision for credit loss expense and represents management’s best estimate of the net amount expected to be collected from loans receivable as of the date of the consolidated statements of financial condition. Confirmed losses are charged against the ACL. Subsequent recoveries, if any, are credited to the ACL. We perform an analysis of the adequacy of the ACL at least quarterly. Management estimates the required ACL balance using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations, estimated collateral values, economic conditions, and other factors. The ACL consists of: (i) a specific allowance established for probable losses on individually identified impaired loans, (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 life of loan; and (iii) a qualitative allowance 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. Accrued interest is excluded from our expected credit loss estimates. Expected credit losses are estimated over the contractual term of the loans, adjusted for 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. A loan is deemed impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. We measure expected credit losses on all impaired loans individually 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 impaired loans for which the accrual of interest has been discontinued are applied first to principal and then to interest income. Loans for which the terms have been modified by granting a concession that normally would not be provided and where the borrower is experiencing financial difficulties are considered troubled debt restructurings (“TDRs”) and classified as impaired. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls, generally, are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The impairment amount on a collateral dependent loan is generally charged-off to the ACL and the impairment amount on a loan, that is not collateral dependent, is set-up as a specific reserve. TDRs are also measured at the present value of estimated future cash flows using the loan’s effective rate at inception or at the fair value of collateral, less costs to sell, if repayment is expected solely from the collateral. For TDRs that subsequently default, we determine the amount of reserve in accordance with the accounting policy for the ACL. At September 30, 2020, 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 (HELOC and other) 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 than SFR mortgage loans. 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. Commercial and industrial loans are also considered to have a greater degree of credit risk than SFR mortgage loans due to the fact 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). 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. SBA loans originated as part of the Paycheck Protection Program (“PPP”) established by the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) have additional credit enhancement provided by the U.S. Small Business Administration for up to 100% of the loan amount. As of September 30, 2020, PPP loans totaled $255.8 million, net of $4.1 million in unamortized fees which are being amortized over their estimated life. During the three months ended September 30, 2020, the Company extended its estimate for the average life of our PPP loans to twelve months from nine months. The twelve month estimated life of PPP loans is based on our understanding of our clients' cash use, expected forgiveness probability, and loan forgiveness process. 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. Consumer loans may have greater risk than SFR mortgage loans 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 considered to carry a higher degree of credit risk due to their unique cash flows. Credit risk on this asset class is also managed through the completion of regular third party automated valuation models (“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 loan to value (“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 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, impaired at the date of discharge, 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. Initially, all TDRs are reported as impaired. Generally, TDRs are classified as impaired loans and reported as TDRs for the remaining life of the loan. Impaired and 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. Troubled Debt Restructuring (TDR) Relief: Under U.S. GAAP, banks are required to assess modifications to a loan’s terms for potential classification as a TDR. A loan to a borrower experiencing financial difficulty is classified as a TDR when a lender grants a concession that it would otherwise not consider, such as a payment deferral or interest concession. 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 section 4013 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 estimated credit losses for the unused portion 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 factors that are consistent with the ACL methodology for loans using the expected loss factors and a draw down factor applied to the underlying borrower risk and facility grades. 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. Available-for-Sale Debt Securities: 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 is established for losses on available-for-sale debt securities due to credit losses and is 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. 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, reserve for loss on repurchased loans, reserve for unfunded loan commitments, realization of deferred tax assets, the valuation of goodwill and other intangible assets, mortgage banking, other derivatives, Hypothetical Liquidation at Book Value (“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. Recent Accounting Guidance, Not Yet Effective: In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). The amendments in ASU 2019-12 simplify the accounting for income taxes by removing certain exceptions for investments, intra-period allocations, and interim calculations, and adding guidance to reduce the complexity of applying Topic 740. ASU 2019-12 will be effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2020. We will adopt this guidance on January 1, 2021. We do not expect that the adoption of these amendments will have a material effect on our consolidated financial statements. In March 2020, the Financial Accounting Standards Board FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) , which provides optional guidance, for a limited period of time, to ease the potential burden in accounting for (or recognizing the

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). 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. Level 2 securities include SBA loan pool securities, U.S. government agency and U.S. government sponsored enterprise residential mortgage-backed securities, non-agency residential mortgage-backed securities, non-agency commercial mortgage-backed securities, collateralized loan obligations, and corporate debt securities. 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 September 30, 2020 or December 31, 2019. 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 September 30, 2020 Assets Securities available-for-sale: SBA loan pools securities $ 17,807 $ — $ 17,807 $ — U.S. government agency and U.S. government sponsored enterprise residential mortgage-backed securities 107,431 — 107,431 — U.S. government agency and U.S. government sponsored enterprise collateralized mortgage obligations 218,396 — 218,396 — Municipal securities 69,233 — 69,233 — Non-agency residential mortgage-backed securities 163 — 163 — Collateralized loan obligations 685,931 — 685,931 — Corporate debt securities 146,906 — 146,906 — Loans held-for-sale, carried at fair value 1,849 — 466 1,383 Derivative assets: Interest rate swaps and caps (1) 8,163 — 8,163 — Foreign exchange contracts (1) 45 — 45 — Liabilities Derivative liabilities: Interest rate swaps and caps (2) 8,749 — 8,749 — Foreign exchange contracts (2) 14 — 14 — December 31, 2019 Assets Securities available-for-sale: U.S. government agency and U.S. government sponsored enterprise residential mortgage-backed securities $ 36,456 $ — $ 36,456 $ — U.S. government agency and U.S. government sponsored enterprise collateralized mortgage obligations 91,299 — 91,299 — Municipal securities 52,689 — 52,689 — Non-agency residential mortgage-backed securities 196 — 196 — Collateralized loan obligations 718,361 — 718,361 — Corporate debt securities 13,579 — 13,579 — Loans held-for-sale, carried at fair value 22,642 — 3,409 19,233 Derivative assets: Interest rate swaps and caps (1) 3,445 — 3,445 — Foreign exchange contracts (1) 138 — 138 — Liabilities Derivative liabilities: Interest rate swaps and caps (2) 3,717 — 3,717 — Foreign exchange contracts (2) 136 — 136 — (1) Included in other assets in the Consolidated Statements of Financial Condition.

The significant unobservable inputs used in the fair value measurement of our loans repurchased from GNMA loan pools at September 30, 2020 and December 31, 2019 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. 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: September 30, 2020 December 31, 2019 ($ in thousands) Fair Value Unpaid Principal Balance Difference Fair Value Unpaid Principal Balance Difference Loans held-for-sale, carried at fair value: Total loans $ 1,849 $ 2,149 $ (300) $ 22,642 $ 23,455 $ (813) Nonaccrual loans (1) 651 750 (99) 8,125 8,370 (245) (1) Includes loans guaranteed by the U.S. government of $0.2 million and $6.7 million at September 30, 2020 and December 31, 2019. There were no loans held-for-sale that were 90 days or more past due and still accruing interest as of September 30, 2020 and December 31, 2019. The assets accounted for under the fair value option are initially measured at fair value. Gains and losses from initial measurement and subsequent changes in fair value are recognized in earnings. The following table presents changes in fair value related to initial measurement and subsequent changes in fair value included in earnings for these assets measured at fair value for the periods indicated: Three Months Ended Nine Months Ended ($ in thousands) 2020 2019 2020 2019 Net gains (losses) from fair value changes: Fair value adjustment for loans held-for-sale $ 24 $ 17 $ (1,537) $ 77 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. Assets and Liabilities Measured on a Non-Recurring Basis Impaired Loans: The fair value of impaired loans with specific allocations of the ACL based on collateral is generally based on recent real estate appraisals and automated valuation models (“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 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.

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 September 30, 2020. Accrued interest receivable on debt securities available-for-sale totaled $6.0 million and $5.6 million at September 30, 2020 and December 31, 2019, and is included within other assets in the accompanying consolidated statements of financial condition. Accrued interest receivable is excluded from the estimate of expected credit losses. At September 30, 2020 and December 31, 2019, there were no holdings of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10 percent of our stockholders’ equity.

At December 31, 2019, our securities available-for-sale portfolio consisted of 70 securities, of which 60 securities were in an unrealized loss position. We monitor our securities portfolio to ensure it has adequate credit support. The majority of unrealized losses are related to our collateralized loan obligations. We also consider the lowest credit rating for identification of credit impairment for other securities. As of September 30, 2020, all of our collateralized loan obligations investment securities in an unrealized loss position received an investment grade credit rating. The decline in fair value 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 these 51 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. During the three and nine months ended September 30, 2020, no allowance for credit losses related to securities available-for-sale was recorded. During the three and nine months ended September 30, 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.

(2) Includes net deferred loan origination costs/(fees) and premiums/(discounts) of $6.2 million and $14.3 million at September 30, 2020 and December 31, 2019. Credit Quality Indicators We categorize loans into risk categories based on relevant information about the ability of borrowers to repay their debt such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. We perform a 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 and grade each loan for 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 credit risk ratings: Pass : Loans risk rated 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 risk rated 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 risk rated 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 risk rated have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that we 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.

Allowance for Credit Losses Our ACL methodology and resulting provision continues to be impacted by the current economic uncertainty and volatility caused by the COVID-19 pandemic. Our 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 September 2020. In contrast to the June 2020 forecasts, these September forecasts reflect a more favorable view of the economy (i.e. higher GDP growth rates and lower unemployment rates). Despite this, the Company-specific economic view recognizes that the foreseeable future is uncertain with respect to the search for a vaccine and effective treatments for COVID-19; the lack of clarity regarding the timing and amount of a potential government stimulus; the unknown impact of the COVID-19 pandemic on the economy and industry segments; and the unknown benefit from Federal Reserve and other government actions. Accordingly, the ACL level and resulting provision reflect these uncertainties. 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 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. We evaluate all impaired loans individually using guidance from ASC 310 primarily through the evaluation of cash flows or collateral values. 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 loan loss, and partially or fully charging off the principal balance. We maintain the allowance for loan losses at a level that is considered adequate to cover the expected credit losses in the loan portfolio. The reserve for unfunded loan commitments is established to cover the expected credit losses for the estimated level of funding of these loan commitments, except for unconditionally cancellable commitments for which no reserve is required under ASC 326. At September 30, 2020 and December 31, 2019, the reserve for unfunded loan commitments was $3.2 million and $4.1 million, respectively, and was included in accrued expenses and other liabilities on the consolidated statements of financial condition. The credit risk monitoring system is designed to identify impaired 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 allowance for credit losses. Further, the Board of Directors provides oversight and guidance for management’s allowance evaluation process.

Included in the 2019 loan loss provision was $3.0 million due to this charge-off increasing the loss factor for commercial and industrial loans used in our allowance for loan loss calculation. On October 22, 2019, in connection with this matter, 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 1, 2020, the case was re-filed in the Superior Court of the State of California, Count of San Diego (Case No. 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. 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, we undertook an extensive collateral review of all commercial lending relationships $5.0 million and above not secured by real estate, consisting of 53 loans representing $536.0 million in commitments. 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 will be sufficient to identify all such issues. Accrued interest receivable on loans receivable, net totaled $25.8 million and $18.9 million at September 30, 2020 and December 31, 2019, and is included within other assets in the accompanying consolidated statements of financial condition. Accrued interest receivable is excluded from the estimate of expected credit losses.

During the three and nine months ended September 30, 2019, we sold $144 thousand and $374.8 million in single family residential mortgage loans, resulting in gains of $8 thousand and $1.8 million. Non-Traditional Mortgage Loans (“NTM”) Our NTM portfolio is comprised of three interest only products: Green Loans, Interest Only loans and a small number of loans with the potential for negative amortization. The initial credit guidelines for the NTM portfolio were established based on the borrower's Fair Isaac Corporation (“FICO”) score, LTV ratio, property type, occupancy type, loan amount, and geography. Additionally, from an ongoing credit risk management perspective, we have determined that the most significant performance indicators for NTMs are LTV ratios and FICO scores. We review the NTM loan portfolio periodically by refreshing FICO scores on the Green Loans and HELOCs and ordering third party automated valuation models (AVMs) to confirm collateral values. We no longer originate NTM loans.

FEDERAL HOME LOAN BANK ADVANCES AND OTHER BORROWINGS	FEDERAL HOME LOAN BANK ADVANCES AND OTHER BORROWINGSThe following table presents advances from the FHLB as of the dates indicated: ($ in thousands) September 30, December 31, Fixed rate: Outstanding balance $ 566,000 (1) $ 730,000 Interest rates ranging from — % (2) 1.82 % Interest rates ranging to 3.32 % 3.32 % Weighted average interest rate 2.39 % 2.66 % Variable rate: Outstanding balance $ — $ 465,000 Weighted average interest rate — % 1.66 % (1) Excludes $6.5 million of unamortized debt issuance costs at September 30, 2020. (2) Includes $10.0 million in FHLB recovery advances with an interest rate of 0.00%, consisting of $5.0 million with a maturity date of November 27, 2020 and $5.0 million with a maturity date of May 27, 2021. Each advance is payable at its maturity date. Advances paid early are subject to a prepayment penalty. In June 2020, we repaid early a $100.0 million FHLB term advance with a weighted average interest rate of 2.07% and incurred a $2.5 million debt extinguishment fee that is included in other noninterest expense in the consolidated statements of operations. Additionally, in June 2020 we refinanced $111.0 million of FHLB term advances to take advantage of the rapid decline in market interest rates. At the end of the third quarter of 2020, FHLB advances included no overnight borrowings, $105.0 million maturing within three months, and $461.0 million maturing beyond three months with a weighted average life of 4.7 years and weighted average interest rate of 2.51%. At September 30, 2020 and December 31, 2019, the Bank’s advances from the FHLB were collateralized by certain real estate loans with an aggregate unpaid principal balance of $2.41 billion and $3.05 billion. Based on this collateral, the Bank was eligible to borrow an additional $890.0 million at September 30, 2020. The Bank’s investment in capital stock of the FHLB of San Francisco totaled $17.6 million and $32.3 million at September 30, 2020 and December 31, 2019. During the second quarter of 2020, we expanded our existing secured borrowing capacity with the Federal Reserve Bank of San Francisco (“Federal Reserve”) by participating in its Borrower-in-Custody (“BIC”) program. As a result, our borrowing capacity with the Federal Reserve increased to $427.7 million at September 30, 2020. Prior to participating in the BIC program, the Bank only pledged securities as collateral for access to the discount window. At September 30, 2020, the Bank has pledged certain qualifying loans with an unpaid principal balance of $879.9 million and securities with a carrying value of $23.5 million as collateral for this line of credit. Borrowings under the BIC program are overnight advances with interest chargeable at the discount window (“primary credit”) borrowing rate. There were no borrowings under this arrangement for the three and nine months ended September 30, 2020 and 2019. The Bank maintained available unsecured federal funds lines with five correspondent banks totaling $185.0 million, with no outstanding borrowings at September 30, 2020. The Bank also maintained repurchase agreements and had no outstanding securities sold under agreements to repurchase at September 30, 2020 and December 31, 2019. Availabilities and terms on repurchase agreements are subject to the counterparties' discretion and the pledging of additional investment securities.

INCOME TAXES

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES For the three and nine months ended September 30, 2020, income tax expense (benefit) was $2.4 million and $(5.1) million, resulting in an effective tax rate of 12.9% and 35.9%. For the three and nine months ended September 30, 2019, income tax (benefit) expense was $(5.6) million and $1.4 million and the effective tax rate was 28.4% and 12.9%. Our effective tax rate for the three and nine months ended September 30, 2020 differs from the 21% federal statutory rate due to the impact of state taxes as well as various permanent tax differences. For interim periods, we generally utilize the estimated annual effective tax rate method under which we determine our provision (benefit) for income taxes based on the current estimate of our annual effective tax rate. For the three and nine months ended September 30, 2020, we utilized the discrete effective tax rate method for recording income taxes. We believe the use of the discrete effective tax rate method is more appropriate than the annual effective tax rate method as minor changes in the Company's estimated ordinary income for the entire year would have a significant effect on the estimated annual effective tax rate and would result in sizable variations in the customary relationship between income tax expense (benefit) and pretax accounting income (loss). Based on our actual and projected level of earnings and permanent tax differences for 2020, our estimated effective tax rate for the full year was refined this quarter to a negative tax rate ranging from approximately 10% to 15%. As a result of the change, we expect our fourth quarter effective tax rate to be approximately 25%. We account for income taxes by recognizing deferred tax assets and liabilities based upon temporary differences between the amounts for financial reporting purposes and tax basis of its assets and liabilities. 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, such as future reversal of existing taxable temporary differences, future taxable income exclusive of reversing temporary differences and carryforwards, taxable income in prior carryback year(s), and 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 of $43.7 million and $44.9 million at September 30, 2020 and December 31, 2019, respectively. 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 $1.1 million and $977 thousand at September 30, 2020 and December 31, 2019, respectively. We do not believe that the unrecognized tax benefits will change materially in the next twelve months. As of September 30, 2020, the total unrecognized tax benefit that, if recognized, would impact the effective tax rate was $846 thousand. At September 30, 2020 and December 31, 2019, we had no accrued interest or penalties. In the event we are assessed interest and/or penalties by federal or state tax authorities, such amounts will be classified in 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. We are no longer subject to examination by U.S. federal taxing authorities for years before 2016. The statute of limitations for the assessment of California franchise taxes has expired for tax years before 2014 (other state income and franchise tax statutes of limitations vary by state).

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. During the three and nine months ended September 30, 2020, changes in fair value of interest rate swaps and caps on loans and foreign exchange contracts were a gain of $3 thousand and loss of $285 thousand, compared to a gain of $517 thousand and a loss of $9.3 million for the three and nine months ended September 30, 2019, and were included in other income on the consolidated statements of operations. For the three and nine months ended September 30, 2019, other income included a $603 thousand gain and $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 the third quarter of 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.

We have entered into agreements with counterparty financial institutions, which include master netting agreements that provide for the net settlement of all contracts with a single counterparty in the event of default. We elect, however, to account for all derivatives with counterparty institutions on a gross basis.

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 $1,000 per share liquidation preference. The following table presents our total outstanding preferred stock as of the dates indicated: September 30, 2020 December 31, 2019 ($ in thousands) Shares Outstanding Liquidation Preference Carrying Value Shares Outstanding Liquidation Preference Carrying Value Series D 7.375% non-cumulative perpetual 93,270 $ 93,270 $ 89,922 96,629 $ 96,629 $ 93,162 Series E 7.00% non-cumulative perpetual 98,702 98,702 94,956 100,477 100,477 96,663 Total 191,972 $ 191,972 $ 184,878 197,106 $ 197,106 $ 189,825 Series D Preferred Stock During the three and nine months ended September 30, 2020, we repurchased depositary shares (Series D Depositary Shares), each representing a 1/40 th interest in a share of Series D Preferred Stock, liquidation amount of $1,000 per share of Series D Preferred Stock, resulting in the repurchase of 100 and 134,410 outstanding Series D Depositary Shares and the related retirement of 3 and 3,360 outstanding shares of Series D Preferred Stock. During the three and nine months ended September 30, 2020 we paid $2 thousand and $2.7 million to repurchase Series D Preferred Stock, resulting in a $0 and $541 thousand difference between the consideration paid and the repurchased shares' carrying value. When the consideration paid to repurchase shares exceeds the repurchased shares' carrying value, the difference reduces net income allocated to common shareholders. When the consideration paid to repurchase shares is less than the repurchased shares' carrying value, the difference increases net income allocated to common shareholders. 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 Depository Shares and the related retirement of 18,371 outstanding shares of Series D Preferred Stock. During the nine-month period ended September 30, 2019 we paid $19.4 million to repurchase Series D Preferred Stock, resulting in a $1.7 million difference between the consideration paid and the repurchased shares' carrying value. Series E Preferred Stock During the three and nine months ended September 30, 2020, we repurchased depositary shares (Series E Depositary Shares), each representing a 1/40 th interest in a share of Series E Preferred Stock, liquidation amount of $1,000 per share of Series E Preferred Stock, resulting in the repurchase of 6,502 and 70,967 outstanding Series E Depositary Shares and the related retirement of 163 and 1,774 outstanding shares of Series E Preferred Stock. During the three and nine months ended September 30, 2020, we paid $163 thousand and $1.7 million to repurchase Series E Preferred Stock, resulting in a $6 thousand and $27 thousand difference between the consideration paid and the repurchased shares' carrying value. 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 Depository Shares and the related retirement of 24,523 outstanding shares of Series E Preferred Stock. During the nine months ended September 30, 2019. we paid $26.6 million to repurchase Series E Preferred Stock, resulting in a $3.4 million difference between the consideration paid and the repurchased shares' carrying value. Share Repurchase Program On February 10, 2020, we announced that our Board of Directors (the “Board”) authorized the repurchase of up to $45 million of our common stock. The repurchase authorization expires in February 2021, however given current macroeconomic conditions and the COVID-19 pandemic, we have suspended common stock repurchases for the immediate future. There were no repurchases of common stock for the three months ended September 30, 2020. During the nine months ended September 30, 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 may 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 will depend on a variety of factors including price, trading volume, corporate and regulatory requirements, and market conditions. Change in Accumulated Other Comprehensive (Loss) Income ("AOCI") 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.

VARIABLE INTEREST ENTITIES

VARIABLE INTEREST ENTITIES	9 Months Ended
	Sep. 30, 2020
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 variable interest entity (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. 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 the 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 September 30, 2020, we have a $3.5 million repurchase reserve related to this VIE. 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 Hypothetical Liquidation at Book Value (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 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 $27.8 million and $29.3 million at September 30, 2020 and December 31, 2019. The following table presents information regarding activity in our alternative energy partnerships for the periods indicated: Three Months Ended Nine Months Ended ($ in thousands) 2020 2019 2020 2019 Fundings $ — $ — $ 3,631 $ 235 Cash distribution from investment 611 534 1,612 1,529 Gain (loss) on investments in alternative energy partnerships 1,430 940 (308) (655) Income tax credits recognized — 862 — 2,585 Tax expense (benefit) recognized from HLBV application 185 254 (111) (177) 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) September 30, December 31, Cash $ 3,101 $ 4,224 Equipment, net of depreciation 242,988 248,920 Other assets 7,291 6,301 Total unconsolidated assets $ 253,380 $ 259,445 Total unconsolidated liabilities $ 6,048 $ 7,143 Maximum loss exposure $ 27,786 $ 32,525 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 $27.8 million, which is our recorded investment amount at September 30, 2020. 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, but also through the significant tax benefits, including federal tax credits generated from the investments. 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.). Qualified Affordable Housing Partnerships We invest in limited partnerships that operate qualified affordable housing projects. The returns on these investments are generated primarily through allocated Federal tax credits and other tax benefits. In addition, these investments contribute to our compliance with 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.

LOAN COMMITMENTS AND OTHER RELATED ACTIVITIES	LOAN COMMITMENTS AND OTHER RELATED ACTIVITIES Some financial instruments, such as unfunded loan commitments, credit lines, letters of credit, and overdraft protection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Risk of credit loss exists up to the face amount of these instruments. The same credit policies are used to make such commitments as are used for originating loans, including obtaining collateral at exercise of the commitment.

Related Party Transactions [Abstract]
RELATED-PARTY TRANSACTIONS	RELATED-PARTY TRANSACTIONS Certain of our executive officers and directors, and their related interests, are customers of, or have had transactions with, the Bank in the ordinary course of business, including deposits, loans and other financial services related transactions. From time to time, the Bank may make loans to executive officers and directors, and their related interests, in the ordinary course of business and on substantially the same terms and conditions, including interest rates and collateral, as those of comparable transactions with non-insiders prevailing at the time, in accordance with the Bank’s underwriting guidelines. These loans do not involve more than the normal risk of collectability or present other unfavorable features. As of September 30, 2020, no related party loans were categorized as nonaccrual, past due, restructured, or potential problem loans. Transactions with Related Parties The Company and the Bank have engaged in transactions described below with the Company’s current or former directors, executive officers, and beneficial owners of more than 5 percent of the outstanding shares of the Company’s voting common stock and certain persons related to them. As previously disclosed, the Company’s Board of Directors has authorized and directed the Company to provide indemnification, advancement, and/or reimbursement for the costs of separate, independent counsel retained by any then-current officer or director, in their individual capacity, with respect to matters related to (i) an investigation by the Special Committee of the Company’s Board of Directors, (ii) a formal order of investigation issued by the SEC on January 4, 2017 (since resolved), and (iii) any related civil or administrative proceedings against the Company as well as officers and directors currently or previously associated with the Company (collectively, the “Indemnity Matters”). During the three and nine months ended September 30, 2020, indemnification costs paid by the Company included $298 thousand and $302 thousand incurred by the Company’s former Interim Chief Financial Officer and Chief Strategy Officer, J. Francisco A. Turner. Indemnification costs paid by the Company for the Company's former Chair, President, and Chief Executive Officer, Steven A. Sugarman were $198 thousand for the nine months ended September 30, 2020. Indemnification costs were also paid on behalf of certain current and former executive officers and directors in amounts less than $120 thousand for the three and nine months ended September 30, 2020. During the three and nine months ended September 30, 2019, indemnification costs paid by the Company included $3.5 million and $10.5 million incurred by the Company’s former Chair, President, and Chief Executive Officer, Steven A. Sugarman; and $497 thousand and $646 thousand incurred by the Company's former General Counsel Emeritus John Grosvenor. Indemnification costs for the Company’s former Interim Chief Financial Officer and Chief Strategy Officer, J. Francisco A. Turner and the Company’s former Chief Financial Officer, James J. McKinney were $769 thousand, jointly incurred for the nine months ended September 30, 2019; and $180 thousand for the Bank’s former director, Cynthia Abercrombie for the nine months ended September 30, 2019. Indemnification costs were also paid on behalf of certain current and former executive officers and directors in amounts less than $120 thousand for the three and nine months ended September 30, 2019.

LITIGATION	LITIGATION From time to time, we are involved as plaintiff or defendant in various legal actions arising in the normal course of business. In accordance with applicable accounting guidance, we establish an accrued liability when those matters present loss contingencies that are both probable and estimable. We continue to monitor the matters for further developments that could affect the amount of the accrued liability that has been previously established. While the ultimate liability with respect to legal actions cannot be determined at this time, we believe that damages, if any, and other amounts relating to pending matters are not likely to be material to the consolidated financial statements.

The Notes will mature on October 30, 2030. From and including the issue date to, but excluding, October 30, 2025 or the date of earlier redemption, the Notes will 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 Notes will bear interest at a floating rate per annum equal to a benchmark rate, which is expected to be Three-Month Term Secured Overnight Financing Rate (SOFR) (as defined in the Indenture), plus a spread. The Notes are subordinated in right of payment to the payment of the Company’s existing and future Senior Debt and structurally subordinated to all of the Company’s subsidiaries’ existing and future indebtedness and other obligations. The Company may, at its option, redeem the Notes in whole or in part on October 30, 2025 and on any interest payment date thereafter. We have evaluated events from the date of the consolidated financial statements on September 30, 2020 through the issuance of these consolidated financial statements included in this Quarterly Report on Form 10-Q.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying unaudited interim consolidated financial statements have been prepared pursuant to Article 10 of SEC Regulation S-X and other SEC rules and regulations for reporting on the Quarterly Report on Form 10-Q. Accordingly, certain disclosures required by U.S. generally accepted accounting principles (“GAAP”) are not included herein. These interim statements should be read in conjunction with the consolidated financial statements and notes included in the Annual Report on Form 10-K for the year ended December 31, 2019 filed by us with the SEC. The December 31, 2019 consolidated statements of financial condition presented herein has been derived from the audited financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC.
Reclassification	In the opinion of management of the Company, the accompanying unaudited interim consolidated financial statements reflect all of the adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial condition and consolidated results of operations as of the dates and for the periods presented.
Principles of Consolidation	Principles of Consolidation: The accompanying unaudited consolidated financial statements include the accounts of the Company and its consolidated subsidiaries as of September 30, 2020 and December 31, 2019 and for the three and nine months ended September 30, 2020 and 2019. Significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its then wholly-owned subsidiaries.
Adopted Accounting Pronouncements and Significant Accounting Policies	Adopted Accounting Pronouncements: On January 1, 2020, we adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326) (“ASU 2016-13”), which replaces the incurred loss impairment methodology with a methodology that reflects current expected credit losses (“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 available-for-sale (“AFS”) debt securities to be recorded through an allowance for credit losses. In addition, ASU 2016-13 modifies the other-than-temporary impairment (“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 . This transition adjustment reflects the development of our models to estimate lifetime expected credit losses on our loans, unfunded commitments, and other off-balance sheet credit exposure primarily using a lifetime loss methodology. 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) Significant Accounting Policies: The accounting and reporting policies of the Company are based upon GAAP and conform to predominant practices within the banking industry. We have not made any significant changes in our critical accounting policies from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC, except for the accounting for loans and the allowance for credit losses, the allowance for credit losses on unfunded loan commitments, troubled debt restructurings, and available-for-sale debt securities as described below. Allowance for Credit Losses (ACL): The ACL is a reserve established through a provision for credit loss expense and represents management’s best estimate of the net amount expected to be collected from loans receivable as of the date of the consolidated statements of financial condition. Confirmed losses are charged against the ACL. Subsequent recoveries, if any, are credited to the ACL. We perform an analysis of the adequacy of the ACL at least quarterly. Management estimates the required ACL balance using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations, estimated collateral values, economic conditions, and other factors. The ACL consists of: (i) a specific allowance established for probable losses on individually identified impaired loans, (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 life of loan; and (iii) a qualitative allowance 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. Accrued interest is excluded from our expected credit loss estimates. Expected credit losses are estimated over the contractual term of the loans, adjusted for 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. A loan is deemed impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. We measure expected credit losses on all impaired loans individually 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 impaired loans for which the accrual of interest has been discontinued are applied first to principal and then to interest income. Loans for which the terms have been modified by granting a concession that normally would not be provided and where the borrower is experiencing financial difficulties are considered troubled debt restructurings (“TDRs”) and classified as impaired. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls, generally, are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The impairment amount on a collateral dependent loan is generally charged-off to the ACL and the impairment amount on a loan, that is not collateral dependent, is set-up as a specific reserve. TDRs are also measured at the present value of estimated future cash flows using the loan’s effective rate at inception or at the fair value of collateral, less costs to sell, if repayment is expected solely from the collateral. For TDRs that subsequently default, we determine the amount of reserve in accordance with the accounting policy for the ACL. At September 30, 2020, 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 (HELOC and other) 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 than SFR mortgage loans. 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. Commercial and industrial loans are also considered to have a greater degree of credit risk than SFR mortgage loans due to the fact 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). 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. SBA loans originated as part of the Paycheck Protection Program (“PPP”) established by the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) have additional credit enhancement provided by the U.S. Small Business Administration for up to 100% of the loan amount. As of September 30, 2020, PPP loans totaled $255.8 million, net of $4.1 million in unamortized fees which are being amortized over their estimated life. During the three months ended September 30, 2020, the Company extended its estimate for the average life of our PPP loans to twelve months from nine months. The twelve month estimated life of PPP loans is based on our understanding of our clients' cash use, expected forgiveness probability, and loan forgiveness process. 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. Consumer loans may have greater risk than SFR mortgage loans 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 considered to carry a higher degree of credit risk due to their unique cash flows. Credit risk on this asset class is also managed through the completion of regular third party automated valuation models (“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 loan to value (“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 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, impaired at the date of discharge, 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. Initially, all TDRs are reported as impaired. Generally, TDRs are classified as impaired loans and reported as TDRs for the remaining life of the loan. Impaired and 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. Troubled Debt Restructuring (TDR) Relief: Under U.S. GAAP, banks are required to assess modifications to a loan’s terms for potential classification as a TDR. A loan to a borrower experiencing financial difficulty is classified as a TDR when a lender grants a concession that it would otherwise not consider, such as a payment deferral or interest concession. 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 section 4013 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 estimated credit losses for the unused portion 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 factors that are consistent with the ACL methodology for loans using the expected loss factors and a draw down factor applied to the underlying borrower risk and facility grades. 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. Available-for-Sale Debt Securities: 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 is established for losses on available-for-sale debt securities due to credit losses and is 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. Recent Accounting Guidance, Not Yet Effective: In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). The amendments in ASU 2019-12 simplify the accounting for income taxes by removing certain exceptions for investments, intra-period allocations, and interim calculations, and adding guidance to reduce the complexity of applying Topic 740. ASU 2019-12 will be effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2020. We will adopt this guidance on January 1, 2021. We do not expect that the adoption of these amendments will have a material effect on our consolidated financial statements. In March 2020, the Financial Accounting Standards Board FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) , which provides optional guidance, for a limited period of time, to ease the potential burden in accounting for (or recognizing the
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, reserve for loss on repurchased loans, reserve for unfunded loan commitments, realization of deferred tax assets, the valuation of goodwill and other intangible assets, mortgage banking, other derivatives, Hypothetical Liquidation at Book Value (“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.
