SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	3 Months Ended
	Mar. 31, 2020
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations: Banc of California, Inc. (collectively, with its consolidated subsidiaries, the Company, we, us and our) is a financial holding company under the Bank Holding Company Act of 1956, as amended, headquartered in Santa Ana, California and incorporated under the laws of Maryland. 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 March 31, 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 showing the unrealized fair value adjustment for loans held for sale separate from the realized net (loss) gain on sale of loans in the statement 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 months ended March 31, 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 March 31, 2020 and December 31, 2019 and for the three months ended March 31, 2020 and 2019 and December 31, 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 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 available-for-sale (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. We adopted ASU 2016-13 using the modified retrospective method for our financial assets measured at cost, including loans receivable and off-balance sheet credit exposures. Results for reporting periods beginning January 1, 2020 are reported under ASU 2016-13 (or Accounting Standards Codification 326), while prior period results continue to be reported under the previously applicable GAAP. The adoption of ASU 2016-13 on January 1, 2020 resulted in an increase of $6.4 million to our allowance for credit losses and an after-tax net decrease in retained earnings of $4.5 million . This transition adjustment reflects the development of our models to estimate lifetime expected credit losses on our loans, unfunded commitments and other off-balance sheet credit exposure primarily using a lifetime loss methodology. The following table presents the impact of adopting ASU 2016-13 on January 1, 2020: ($ 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 Multi-family 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 and 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 and 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 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 March 31, 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 • 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, but have additional credit enhancement 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 Payment Protection Program implemented 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 March 31, 2020 , there were no PPP loans. The availability of funds for the repayment of financing may be substantially dependent on the success of the business itself (which, in turn, is often dependent in part upon general economic conditions). Consumer loans may entail 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 also 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 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 troubled debt restructuring (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. 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 non-accrual status for a minimum period of 6 months. Commercial TDRs are evaluated on a case-by-case basis for determination whether or not to place them on non-accrual 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 and 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 agencies have provided relief from TDR accounting. The main benefits of TDR relief include a capital benefit in the form of reduced risk-weighted assets, as TDRs are more heavily risk-weighted for capital purposes; aging of the loans is frozen, i.e., they will continue to be reported in the same delinquency bucket they were in at the time of modification; and the loans are generally not reported as non-accrual 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 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 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 are 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 credited to 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 and 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 FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12). The amendments in this Update simplify the accounting for income taxes by removing certain exceptions for investments, intraperiod allocations, and interim calculations, and add guidance to reduce the complexity of applying Topic 740. This ASU will be effective for fiscal years, and interim periods within those fiscal years, and interim periods within those fiscal years, beginning after 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)

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 judgment and evaluation for valuation. We had no securities available-for-sale classified as Level 3 at March 31, 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 swaps and caps 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 its 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 its customers foreign exchange products while minimizing its 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 resulted 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 March 31, 2020 Assets Securities available-for-sale: U.S. government agency and U.S. government sponsored enterprise residential mortgage-backed securities $ 104,021 $ — $ 104,021 $ — U.S. government agency and U.S. government sponsored enterprise collateralized mortgage obligations 139,419 — 139,419 — Municipal securities 54,385 — 54,385 — Non-agency residential mortgage-backed securities 160 — 160 — Collateralized loan obligations 623,571 — 623,571 — Corporate debt securities 47,871 — 47,871 — Loans held-for-sale, carried at fair value 20,234 — 3,107 17,127 Derivative assets: Interest rate swaps and caps (1) 8,242 — 8,242 — Foreign exchange contracts (1) 369 — 369 — Liabilities Derivative liabilities: Interest rate swaps and caps (2) 8,881 — 8,881 — Foreign exchange contracts (2) 182 — 182 — 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 following table presents a reconciliation of assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3), on a consolidated operations basis, for the periods indicated: Three Months Ended March 31, ($ in thousands) 2020 2019 Loans repurchased from GNMA Loan Pools Balance at beginning of period $ 19,233 $ 25,040 Total (losses) gains (realized/unrealized): Included in earnings—fair value adjustment (1,391 ) 3 Additions — — Sales, settlements, and other (715 ) (1,974 ) Balance at end of period $ 17,127 $ 23,069 Loans repurchased from GNMA loan pools had aggregate unpaid principal balances of $19.1 million and $19.8 million as of March 31, 2020 and December 31, 2019 . The significant unobservable inputs used in the fair value measurement of our loans repurchased from GNMA loan pools at March 31, 2020 and December 31, 2019 included an expected loss rate of 1.55 percent for insured loans and 20.00 percent for uninsured loans. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. Fair Value Option Loans Held-for-Sale, Carried at Fair Value: We elected the fair value option for certain SFR mortgage loans held-for-sale. Electing to measure SFR mortgage loans held-for-sale at fair value reduces certain timing differences and better matches changes in the value of these assets with changes in the value of derivatives used as economic hedges for these assets. We also elected to record loans repurchased from GNMA at fair value, as we intend to sell them after curing any defects and, accordingly, they are classified as held-for-sale. Loans previously sold to GNMA that are delinquent more than 90 days are subject to a repurchase option when that condition exists and typically are repurchased by us. To the extent loans are subject to a repurchase option and not repurchased, the loans are re-recognized at fair value and offset by a secured borrowing, as the loans are still legally owned by GNMA. As of March 31, 2020 and December 31, 2019 , there are no loans subject to such repurchase option and accordingly no related secured borrowings. The following table presents the fair value and aggregate principal balance of certain assets, on a consolidated operations basis, under the fair value option: March 31, 2020 December 31, 2019 ($ in thousands) Fair Value Unpaid Principal Balance Difference Fair Value Unpaid Principal Balance Difference Loans held-for-sale, carried at fair value: Total loans $ 20,234 $ 22,675 $ (2,441 ) $ 22,642 $ 23,455 $ (813 ) Non-accrual loans (1) 5,795 6,901 (1,106 ) 8,125 8,370 (245 ) (1) Includes loans guaranteed by the U.S. government of $4.5 million and $6.7 million , respectively, at March 31, 2020 and December 31, 2019 . There were no loans held-for-sale that were 90 days or more past due and still accruing interest as of March 31, 2020 and December 31, 2019 . The assets accounted for under the fair value option are initially measured at fair value. Gains and losses from initial measurement and subsequent changes in fair value are recognized in earnings. The following table presents changes in fair value related to initial measurement and subsequent changes in fair value included in earnings for these assets measured at fair value for the periods indicated: Three Months Ended March 31, ($ in thousands) 2020 2019 Net (losses) gains from fair value changes: Fair value adjustment for loans held for sale $ (1,586 ) $ 1 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 to adjust for differences between the comparable sales and income data available. Such adjustments are typically deemed significant unobservable inputs used for determining fair value and result in a Level 3 classification.

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 March 31, 2020 . Accrued interest receivable on debt securities available-for-sale totaled $5.7 million and $5.6 million at March 31, 2020 and December 31, 2019 , and is included within other assets in the accompanying consolidated balance sheets. This amount is excluded from the estimate of expected credit losses. At March 31, 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, 60 of which 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 March 31, 2020 , nearly all of our non-agency mortgage-backed securities and collateralized loan obligations investment securities in an unrealized loss position received an investment grade credit rating. Although credit spreads widened during the quarter, the decline in fair value is attributable to a combination of changes in interest rates and general volatility in the credit market conditions. We do not have the intent to sell these 54 securities in an unrealized loss position and further believe it is more likely that not that we will not be required to sell these securities before their anticipated recovery.

Credit Quality Indicators We categorize loans into risk categories based on relevant information about the ability of borrowers to service their debt such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. We perform 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 by classifying the loans as to credit risk. This analysis includes all loans delinquent over 60 days and non-homogeneous loans such as commercial and commercial real estate loans. We use the following definitions for risk ratings: Pass : Loans classified as pass are in compliance in all respects with the Bank’s credit policy and regulatory requirements, and do not exhibit any potential or defined weakness as defined under “Special Mention”, “Substandard” or “Doubtful”. Special Mention : Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or lease or of our credit position at some future date. Substandard : Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that 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 is comprised of our allowance for loan losses (ALL) and reserve for unfunded loan commitments. Our ACL and resulting provision was significantly 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 our historical and peer loss data, our current loan portfolio risk profile, and economic forecasts. Loan-level data and credit-risk attributes are incorporated into the model and adjusted based on a peer-multiplier and economic forecasts. The forecasts are based on critical macroeconomic variables with relevant ranges of one to three years which then revert to long-term trends over the life of the loan. We utilized economic forecasts published by our model provider to determine the ACL on January 1, 2020. Subsequent to adoption, we used economic forecasts released by our model provider during the last week of March which included the onset of the pandemic. These latter forecasts included a sharp contraction in annualized GDP growth and a sharp spike in near-term unemployment rates ranging from 8% to 13% , before returning to moderate long-term economic trends. Our visibility at the end of the quarter indicated that local unemployment was heading higher and that the economic recovery would likely be slower. Accordingly, we incorporated qualitative factors to account for this visibility at quarter end related to actual conditions and an economic outlook that was worse than the late March forecasts incorporated into the CECL model. As a result of the COVID-19 pandemic and adoption of CECL, we expect our allowance for credit losses to continue to be impacted in future periods by economic volatility, changing economic forecasts, as well as the related impacts to CECL model assumptions, all of which may be better than or worse than our current estimate. 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 the contractual payment requirements of the loan agreements. Such loans are subject to increased monitoring. Consideration is given to placing the loan on non-accrual status, assessing the need for additional allowance for loan loss, and partial or full charge 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. We maintain a reserve for unfunded loan commitments at a level that is considered adequate to cover expected credit losses for the portion of commitments that ultimately fund. The estimated funding of the loan commitments and credit risk factors are determined based on outstanding loans that share similar credit risk exposure are used to determine the adequacy of the reserve. At March 31, 2020 and December 31, 2019 , the reserve for unfunded loan commitments was $3.9 million and $4.1 million , respectively, and are 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, and to perform periodic evaluation of impairment and 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. In addition, the Board of Directors provides oversight and guidance for management’s allowance evaluation process.

A concession or 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.

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 additional 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, which includes 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.

GOODWILL AND OTHER INTANGIBLE ASSETS, NET	GOODWILL AND OTHER INTANGIBLE ASSETS, NET At March 31, 2020 and December 31, 2019 , we had goodwill of $37.1 million . We evaluate goodwill impairment as of August 31 each year, and more frequently if events or circumstances indicate that there may be impairment. We completed our most recent annual goodwill impairment test as of August 31, 2019 and determined that no goodwill impairment existed. In the first quarter 2020, due to the observed market volatility resulting from the COVID-19 pandemic, we analyzed indicators related to potential goodwill impairment. Based on this analysis, we did no t identify any impairment to goodwill in the first quarter 2020, although there can be no assurance that prolonged market volatility resulting from the COVID-19 pandemic or other factors will not result in impairments to goodwill or other intangibles in future periods. Core deposit intangibles are amortized over their useful lives ranging from four to ten years. As of March 31, 2020 , the weighted average remaining amortization period for core deposit intangibles was approximately 4.5 years .

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES For the three months ended March 31, 2020 , income tax benefit was $2.2 million and the effective tax rate was 24.7% . For the three months ended March 31, 2019 , income tax expense was $2.7 million and the effective tax rate was 27.9% . The company’s 24.7% effective tax rate for the three months ended March 31, 2020 differs from the 21% statutory rate is due to the impact of state taxes as well as various tax credits. The income tax benefit during the first quarter of 2020 was mainly due to the $8.8 million pre-tax book loss recognized, as compared to the $9.8 million pre-tax book income recognized during the first quarter of 2019 . 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 that it was more likely than not that all of the deferred tax assets would be realized; therefore, no valuation allowance was provided against the deferred tax assets of $63.8 million and $44.9 million at March 31, 2020 and December 31, 2019 , respectively. The overall increase in net deferred tax assets was primarily due to an increase in deferred tax assets of $17.6 million from net unrealized losses on securities available-for-sale and $1.9 million from the adoption of ASU 2016-13, offset by an increase in deferred tax liabilities of $0.6 million resulting from year-to-date temporary book-tax differences. 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 $1.0 million and $977 thousand at March 31, 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 March 31, 2020 , the total unrecognized tax benefit that, if recognized, would impact the effective tax rate was $794 thousand . At March 31, 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).

VARIABLE INTEREST ENTITIES

VARIABLE INTEREST ENTITIES	3 Months Ended
	Mar. 31, 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 percent 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 percent . We believe that the loss exposure on its 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 March 31, 2020 , we have a $4.4 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 installed 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 these 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 $27.3 million and $29.3 million at March 31, 2020 and December 31, 2019 .

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, 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.), thereby further limiting our exposure. 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. Therefore, 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 loans, including obtaining collateral at exercise of the commitment. The contractual amount of financial instruments with off-balance-sheet risk was as follows for the dates indicated: March 31, 2020 December 31, 2019 ($ in thousands) Fixed Rate Variable Rate Fixed Rate Variable Rate Commitments to extend credit $ 412 $ 109,701 $ 473 $ 129,495 Unused lines of credit 581 1,162,844 703 1,049,632 Letters of credit 138 5,576 134 5,316 Other Commitments During the three months ended March 31, 2017, the Bank entered into certain definitive agreements which grant the Bank the exclusive naming rights to the Banc of California Stadium, a soccer stadium of The Los Angeles Football Club (LAFC), as well as the right to be the official bank of LAFC. In exchange for the Bank’s rights as set forth in the agreements, the Bank agreed to pay LAFC $100.0 million over a period of 15 years , beginning in 2017 and ending in 2032. The advertising benefits of such rights are amortized on a straight-line basis and recorded as advertising and promotion expense beginning in 2018. During each of the three months ended March 31, 2020 and 2019 , advertising and promotion expense related to the LAFC commitment was $1.7 million . As of March 31, 2020 , the Bank has paid $22.1 million of the $100.0 million commitment. The prepaid commitment balance, net of amortization, was $7.1 million as of March 31, 2020 , and was included in other assets in the consolidated statements of financial condition. At March 31, 2020 , we had unfunded commitments of $17.8 million , $7.6 million , and $501 thousand for affordable housing fund investments, Small Business Investment Company (SBIC) investments, and other investments, respectively.

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, and do not involve more than the normal risk of collectability or present other unfavorable features. As of March 31, 2020 , no related party loans were categorized as nonaccrual, past due, restructured or potential problem loans. The Bank also has an Employee Loan Program which is available to all employees and offers executive officers, directors and principal stockholders that meet the eligibility requirements the opportunity to participate on the same terms as employees generally, provided that any loan to an executive officer, director or principal stockholder must be approved by the Bank’s Board of Directors. The sole benefit provided under the Employee Loan Program is a reduction in loan fees. 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”). Indemnification costs were paid on behalf of certain executive officers and directors in amounts less than $120 thousand for the three months ended March 31, 2020 . During the three months ended March 31, 2019 , indemnification costs paid by the Company included $2.2 million incurred by the Company’s former Chair, President and Chief Executive Officer Steven A. Sugarman; $555 thousand jointly incurred by 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; and $147 thousand incurred by the Company's General Counsel Emeritus John Grosvenor. Indemnification costs were paid on behalf of other former executive officers and other former directors in lesser amounts for the three months ended March 31, 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. As of March 31, 2020 , we have accrued $21.0 million for various litigation filed against the Company and the Bank, including $19.75 million related to the settlement of the securities litigation previously announced by us and described below. There is no expected impact to earnings as a result of the settlement, as the settlement payments will be paid directly by our insurance carriers and we have recorded an insurance receivable for $19.75 million related to this matter. On October 28, 2019, we entered into a Stipulation of Settlement (“Settlement Stipulation”) with the lead plaintiff to settle class action lawsuits that were previously consolidated in the United District Court for the Central District of California (the “Court”) under the caption In re Banc of California Securities Litigation, Case No. SACV 17-00118 AG, consolidated with SACV 17-00138 AG. Under the terms of the Settlement Stipulation, our insurance carriers will pay $19.75 million , which will be distributed to shareholders who purchased our stock between April 15, 2016 and January 20, 2017, after payment of attorney’s fees and costs, to be determined by the Court. We will not be required to contribute any cash to the settlement payments. Pursuant to the settlement, the action against the Company will be dismissed with prejudice. Plaintiff will also dismiss with prejudice its claims against our former Chief Executive Officer and Chairman Steven Sugarman. While we do not believe the plaintiff’s claims are meritorious, we believe that ending the costs and distraction of the litigation is in the best interests of the Company and our shareholders. On March 16, 2020, the Court gave final approval to the settlement and that order is now final. The foregoing description of the settlement does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the complete text of the settlement stipulation that was filed with the Court.

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
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 March 31, 2020 and December 31, 2019 and for the three months ended March 31, 2020 and 2019 and December 31, 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.
Significant Accounting Policies	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 and 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 and 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 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 March 31, 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 • 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, but have additional credit enhancement 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 Payment Protection Program implemented 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 March 31, 2020 , there were no PPP loans. The availability of funds for the repayment of financing may be substantially dependent on the success of the business itself (which, in turn, is often dependent in part upon general economic conditions). Consumer loans may entail 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 also 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 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 troubled debt restructuring (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. 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 non-accrual status for a minimum period of 6 months. Commercial TDRs are evaluated on a case-by-case basis for determination whether or not to place them on non-accrual 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 and 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 agencies have provided relief from TDR accounting. The main benefits of TDR relief include a capital benefit in the form of reduced risk-weighted assets, as TDRs are more heavily risk-weighted for capital purposes; aging of the loans is frozen, i.e., they will continue to be reported in the same delinquency bucket they were in at the time of modification; and the loans are generally not reported as non-accrual 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 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 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 are 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 credited to income is reversed. Recent Accounting Guidance, Not Yet Effective: In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12). The amendments in this Update simplify the accounting for income taxes by removing certain exceptions for investments, intraperiod allocations, and interim calculations, and add guidance to reduce the complexity of applying Topic 740. This ASU will be effective for fiscal years, and interim periods within those fiscal years, and interim periods within those fiscal years, beginning after 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 benefits of) reference rate reform on financial reporting. The amendments in ASU 2020-04 are elective and apply to all entities, subject to meeting certain criteria, that have contract, hedging relationships, and other transactions that reference London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria. When elected, the optional expedients for contract modifications must be applied consistently for all eligible contracts or eligible transactions within the relevant topic or industry subtopic within the codification that contains the guidance that otherwise would be required to be applied. The amendments in ASU 2020-04 are effective for all entities as of March 12, 2020 through December 31, 2022. We are in the process of evaluating the potential impact the discontinuation of LIBOR will have on our contracts and expect to elect the optional expedients and exceptions set forth in the amendments.
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 and 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.
