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 32 banking offices, serving San Diego, Los Angeles, Santa Barbara, and Orange counties in California as of September 30, 2019 . 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, 2018 filed by the Company with the SEC. The December 31, 2018 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, 2018 filed with the SEC, but does not include all of the disclosures required by GAAP for complete financial statements. 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, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019 . Principles of Consolidation: The accompanying unaudited consolidated financial statements include the accounts of the Company and its consolidated subsidiaries as of September 30, 2019 and December 31, 2018 and for the three and nine months ended September 30, 2019 and 2018 . 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: The accounting and reporting policies of the Company are based upon GAAP and conform to predominant practices within the banking industry. The Company has not made any significant changes in its critical accounting policies from those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC, except for the accounting for leases as described below. Leases. The Company determines if an arrangement is a lease at inception. The Company’s operating lease agreements are primarily for real estate space and are included within right of use (ROU) assets and lease liabilities on the September 30, 2019 consolidated balance sheet. The ROU asset is based on the operating lease liabilities adjusted for any prepaid or deferred rent. The Company has elected not to recognize on its consolidated balance sheet leases with terms of one-year or less. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, the Company uses its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment, at lease commencement date in determining the present value of lease payments. Many of the Company’s lessee agreements include options to extend the lease, which the Company does not include in its minimum lease terms unless they are reasonably certain to be exercised. The Company elected the practical expedient to combine its lease and related nonlease components for the Company’s building leases. Rental expense for lease payments related to operating leases is recognized on a straight-line basis over the lease term 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 allowance for loan losses (ALLL), 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. Discontinued Operations: During the three months ended March 31, 2017, the Company completed the sale of its Banc Home Loans division, which largely represented the Company's Mortgage Banking segment. In accordance with Accounting Standards Codification (ASC) 205-20, the Company determined that the sale of the Banc Home Loans division and certain other mortgage banking related assets and liabilities that would be sold or settled separately within one year met the criteria to be classified as a discontinued operation and the related operating results and financial condition have been presented as discontinued operations on the consolidated financial statements. See Note 2 for additional information. Unless otherwise indicated, information included in these notes to the consolidated financial statements is presented on a consolidated operations basis, which includes results from both continuing and discontinued operations, as of December 31, 2018 and for the three and nine months ended September 30, 2018 . There were no material assets, liabilities or operating income as of and for the three and nine months ended September 30, 2019 related to discontinued operations. Restructuring Expense: During the three and nine months ended September 30, 2019 , the Company continued to implement its strategic objective to de-emphasize the production of low margin loan products through its exit from the third-party mortgage origination ("TPMO") and brokered single family lending business. The Company recognized no restructuring costs for the three months ended September 30, 2019 and $2.6 million for the nine months ended September 30, 2019 , associated with the exit from the TPMO and brokered single family lending business and CEO transition. Adopted Accounting Pronouncements: During the nine months ended September 30, 2019 , the following pronouncements applicable to the Company were adopted: In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (ASU) 2016-02 Topic 842, “Leases” which increases transparency and comparability among organizations by requiring the recognition of right of use (ROU) assets and lease liabilities on the balance sheet. Most prominent among the changes in the standard is the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company adopted Topic 842 and related updates effective January 1, 2019 and used the effective date as the date of initial application, and therefore, periods prior to January 1, 2019 were not restated. The Company elected the package of practical expedients, which permits us not to reassess prior conclusions about lease identifications, lease classification and initial direct costs under the new standard. The Company did not elect to apply the hindsight practical expedient pertaining to using hindsight knowledge as of the effective date when determining lease terms and impairment. The Company also has elected the short-term lease recognition exemption (leases with terms 12 months or less) for all leases that qualify, and thus will not recognize ROU assets or lease liabilities for those leases. In addition, the Company elected the practical expedient to not separate lease and non-lease components for all of our leases. Upon adoption, the Company recognized on its consolidated balance sheet ROU assets of approximately $23.3 million (inclusive of an adjustment to remove the Company's existing deferred rent liability of approximately $1.4 million ) with a corresponding operating lease liability of approximately $24.7 million . The standard did not have an impact on our consolidated statements of operations. In addition, the Company's accounting for finance leases remained substantially unchanged. In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment," which amended ASC 350 "Intangibles-Goodwill and Other." The amendments in this ASU simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. ASU 2017-04 is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company has early adopted this guidance prospectively as of August 31, 2019, and the adoption did not have a material impact on our financial statements.

SALE OF BUSINESS UNIT (DISCONTINUED OPERATIONS)	SALE OF BUSINESS UNIT (DISCONTINUED OPERATIONS) Banc Home Loans Sale On March 30, 2017, the Company completed the sale of specific assets and activities related to its Banc Home Loans division to Caliber Home Loans, Inc. (Caliber). The Banc Home Loans division largely represented the Company's Mortgage Banking segment, the activities of which related to originating, servicing, underwriting, funding and selling single family residential (SFR) mortgage loans. Assets sold to Caliber included mortgage servicing rights (MSRs) on certain conventional agency SFR mortgage loans.

FAIR VALUES OF FINANCIAL INSTRU

FAIR VALUES OF FINANCIAL INSTRUMENTS	9 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUES OF FINANCIAL INSTRUMENTS	FAIR VALUES OF FINANCIAL INSTRUMENTS Fair Value Hierarchy ASC 820-10 establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The topic describes three levels of inputs that may be used to measure fair value: • Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2: Significant observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Assets and Liabilities Measured on a Recurring Basis Securities Available-for-Sale: The fair values of securities available-for-sale are generally determined by quoted market prices in active markets, if available (Level 1). If quoted market prices are not available, the Company primarily employs 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. The Company employs procedures to monitor the pricing service's assumptions and establishes processes to challenge the pricing service's valuations that appear unusual or unexpected. Level 2 securities include U.S. Small Business Administration (SBA) loan pool securities, U.S. government agency and U.S. government sponsored enterprise (GSE) 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. The Company had no securities available-for-sale classified as Level 3 at September 30, 2019 or December 31, 2018 . Loans Held-for-Sale, Carried at Fair Value: The fair value of loans held-for-sale is based on commitments outstanding from investors as well as what secondary market investors are currently offering for portfolios with similar characteristics, except for loans that are repurchased out of GNMA loan pools that become severely delinquent which are valued based on an internal model that estimates the expected loss the Company will incur on these loans. Loans previously sold to GNMA that are delinquent more than 90 days are subject to a repurchase option when that condition exists. These loans are re-recognized at fair value and offset by a secured borrowing, as the loans are still legally owned by GNMA but failed sale accounting treatment under GAAP due to the repurchase option. 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 as well as any accrued interest. As of September 30, 2019 and December 31, 2018 , there were no loans that were delinquent more than 90 days and eligible to be repurchased out of GNMA loan pools. Derivative Assets and Liabilities : Interest Rate Swaps and Caps. The Company offers interest rate swaps and caps products to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The fair value of these derivatives is based on a discounted cash flow approach. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of interest rate swaps is classified as Level 2. The Company may use interest rate swaps to offset variability in the fair values of investment securities resulting from changes in market interest rates. During the third quarter of 2019, the Company partially hedged the fair value of the MBS portfolio using interest rate swaps. At the end of the quarter, the Company took advantage of the decline in long-term interest rates and sold the majority of the MBS portfolio and unwound the majority of the interest rate swaps. Foreign Exchange Contracts. The Company offers 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 the Company also enters into offsetting contracts with institutional counterparties to hedge the Company’s foreign exchange rate risk. These back-to-back contracts allow the Company 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 the Company’s 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, 2019 Assets Securities available-for-sale: SBA loan pools securities $ — $ — $ — $ — U.S. government agency and U.S. government sponsored enterprise residential mortgage-backed securities 40,374 — 40,374 — Non-agency residential mortgage-backed securities 277 — 277 — Collateralized loan obligations 735,011 — 735,011 — Loans held-for-sale, carried at fair value 23,936 — 3,431 20,505 Derivative assets: Interest rate swaps and caps (1) 4,773 — 4,773 — Foreign exchange contracts (1) 36 — 36 — Liabilities Derivative liabilities: Interest rate swaps and caps (2) 5,198 — 5,198 — Interest rate swaps and caps - mortgage-backed securities (3) 325 — 325 — Foreign exchange contracts (2) 30 — 30 — December 31, 2018 Assets Securities available-for-sale: SBA loan pools securities $ 910 $ — $ 910 $ — U.S. government agency and U.S. government sponsored enterprise residential mortgage-backed securities 437,442 — 437,442 — Non-agency residential mortgage-backed securities 427 — 427 — Non-agency commercial mortgage-backed securities 132,199 — 132,199 — Collateralized loan obligations 1,421,522 — 1,421,522 — Loans held-for-sale, carried at fair value (4) 27,180 — 2,140 25,040 Derivative assets: Interest rate swaps and caps (1) 1,534 — 1,534 — Liabilities Derivative liabilities: Interest rate swaps and caps (2) 1,600 — 1,600 — (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 September 30, Nine Months Ended September 30, ($ in thousands) 2019 2018 2019 2018 Loans repurchased from GNMA Loan Pools (1) Balance at beginning of period $ 21,075 $ 33,234 $ 25,040 $ 98,940 Total gains (losses) (realized/unrealized): Included in earnings—fair value adjustment 2 (22 ) (1 ) (276 ) Additions 406 711 406 28,096 Sales, settlements, and other (978 ) (8,167 ) (4,940 ) (101,004 ) Balance at end of period $ 20,505 $ 25,756 $ 20,505 $ 25,756 (1) Includes loans repurchased from GNMA Loan Pools of discontinued operations, which is included in Assets of Discontinued Operations in the Consolidated Statements of Financial Condition, of zero and $20.9 million , respectively, for the three months ended September 30, 2019 and 2018 and $17.3 million and $32.3 million for the nine months ended September 30, 2019 and 2018 in balance at beginning of period, and zero and $17.7 million , respectively, for both the three and nine months ended September 30, 2019 and 2018 in balance at end of period. The significant unobservable inputs used in the fair value measurement of the Company's loans repurchased from GNMA loan pools at September 30, 2019 and December 31, 2018 included an expected loss rate of 1.55 percent for insured loans and 20.00 percent for uninsured loans. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. Fair Value Option Loans Held-for-Sale, Carried at Fair Value: The Company elected the fair value option for certain SFR mortgage loans held-for-sale. Electing to measure SFR mortgage loans held-for-sale at fair value reduces certain timing differences and better matches changes in the value of these assets with changes in the value of derivatives used as economic hedges for these assets. The Company also elected to record loans repurchased from GNMA at fair value, as the Company intends to sell them after curing any defects and, accordingly, they are classified as held-for-sale. Loans previously sold to GNMA that are delinquent more than 90 days are subject to a repurchase option when that condition exists. These loans are re-recognized at fair value and offset by a secured borrowing, as the loans are still legally owned by GNMA. The following table presents the fair value and aggregate principal balance of certain assets, on a consolidated operations basis, under the fair value option: September 30, 2019 December 31, 2018 ($ in thousands) Fair Value Unpaid Principal Balance Difference Fair Value Unpaid Principal Balance Difference Loans held-for-sale, carried at fair value in continuing operations: Total loans $ 23,936 $ 24,746 $ (810 ) $ 7,690 $ 7,906 $ (216 ) Non-accrual loans (1) 8,203 8,436 (233 ) 2,427 2,538 (111 ) Loans held-for-sale, carried at fair value in discontinued operations: Total loans $ — $ — $ — $ 19,490 $ 20,027 $ (537 ) Non-accrual loans (2) — — — 8,430 8,496 (66 ) (1) Includes loans guaranteed by the U.S. government of $7.2 million and $1.6 million , respectively, at September 30, 2019 and December 31, 2018 . (2) Includes loans guaranteed by the U.S. government of zero and $7.6 million , respectively, at September 30, 2019 and December 31, 2018 . There were no loans held-for-sale that were 90 days or more past due and still accruing interest as of September 30, 2019 and December 31, 2018 . The assets accounted for under the fair value option are initially measured at fair value. Gains and losses from initial measurement and subsequent changes in fair value are recognized in earnings. The following table presents changes in fair value related to initial measurement and subsequent changes in fair value included in earnings for these assets measured at fair value for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, ($ in thousands) 2019 2018 2019 2018 Net gains from fair value changes: Net gain on sale of loans (continuing operations) $ 17 $ 11 $ 77 $ 198 Net revenue on mortgage banking activities (discontinued operations) — 30 — 127 Changes in fair value due to instrument-specific credit risk were immaterial for the three and nine months ended September 30, 2019 and 2018 . 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 and income from discontinued operations 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 ALLL 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.

During the first quarter of 2019 , the Company completed the sale of all remaining non-agency commercial mortgage-backed securities totaling $132.2 million resulting in a gain of $9 thousand . During the three and nine months ended September 30, 2019 , the Company sold $380.9 million and $385.8 million , respectively, in mortgage-backed securities resulting in a loss of $5.1 million and $5.0 million , respectively. Additionally, during the three and nine months ended September 30, 2019 , the Company sold zero and $644.5 million , respectively, in collateralized loan obligations resulting in a gain of zero and $143 thousand , respectively. During the first quarter of 2018, the Company completed the sale of all remaining corporate debt securities, totaling $76.8 million resulting in a gain of $4.9 million . At September 30, 2019 , the Company's investment securities portfolio consisted of mortgage-backed securities and collateralized loan obligations. The expected maturities of these types of securities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. At September 30, 2019 and December 31, 2018 , there were no holdings of any one issuer in an amount greater than 10 percent of the Company's stockholders’ equity. The following table presents proceeds from sales and calls of securities available-for-sale and the associated gross gains and losses realized through earnings upon the sales and calls of securities available-for-sale for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, ($ in thousands) 2019 2018 2019 2018 Gross realized gains on sales and calls of securities available-for-sale $ 71 $ 13 $ 279 $ 5,532 Gross realized losses on sales and calls of securities available-for-sale (5,134 ) — (5,134 ) — Net realized (losses) gains on sales and calls of securities available-for-sale $ (5,063 ) $ 13 $ (4,855 ) $ 5,532 Proceeds from sales and calls of securities available-for-sale $ 43,252 $ 283,114 $ 861,008 $ 896,070 Investment securities with carrying values of $64.6 million and $163.0 million as of September 30, 2019 and December 31, 2018 , respectively, were pledged to secure FHLB advances, public deposits and for other purposes as required or permitted by law.

The OTTI was recognized as a result of the Company's ongoing strategic decision to liquidate this longer duration portfolio. During the three and nine months ended September 30, 2018, no OTTI was recorded. At September 30, 2019 , the Company’s securities available-for-sale portfolio consisted of 57 securities, 45 of which were in an unrealized loss position. At December 31, 2018 , the Company’s securities available-for-sale portfolio consisted of 145 securities, 118 of which were in an unrealized loss position. The Company monitors its securities portfolio to ensure it has adequate credit support. The majority of unrealized losses are related to the Company's collateralized loan obligations. The Company also considers the lowest credit rating for identification of potential OTTI for other securities. As of September 30, 2019 , nearly all of the Company's non-agency mortgage-backed securities or collateralized loan obligations investment securities in an unrealized loss position received an investment grade credit rating. The decline in fair value is attributable to changes in interest rates, and not credit quality. Except for the remaining portfolio of 9 mortgage-backed securities which the Company intends to sell, the Company believes there was no further OTTI as of September 30, 2019 . The Company does not have the intent to sell the remaining 45 The following table presents the composition and the repricing and yield information of the investment securities portfolio as of September 30, 2019 : One year or less More than One Year through Five Years More than Five Years through Ten Years More than Ten Years Total ($ in thousands) Fair Value Weighted-Average Yield Fair Value Weighted-Average Yield Fair Value Weighted-Average Yield Fair Value Weighted-Average Yield Fair Value Weighted-Average Yield Securities available-for-sale: U.S. government agency and U.S. government sponsored enterprise residential mortgage-backed securities $ — — % $ — — % $ — — % $ 40,374 2.56 % $ 40,374 2.56 % Non-agency residential mortgage-backed securities 65 2.68 % — — % — — % 212 5.79 % 277 5.06 % Collateralized loan obligations 735,011 3.52 % — — % — — % — — % 735,011 3.52 % Total securities available-for-sale $ 735,076 3.52 % $ — — % $ — — % $ 40,586 2.58 % $ 775,662 3.47 %

These loans are generally interest only for a 15 -year term with a balloon payment due at maturity. At September 30, 2019 and December 31, 2018 , $286 thousand and $0 , respectively, of the Company's Green Loans were non-performing. As a result of their unique payment feature, Green Loans possess higher credit risk; however, management believes the risk is mitigated through the Company’s loan terms and underwriting standards, including its policies on LTV ratios and the Company’s contractual ability to curtail loans when the value of the underlying collateral declines. The Company discontinued origination of Green Loans in 2011. Interest Only Loans Interest only loans are primarily single family residential first mortgage loans with payment features that allow interest only payments in initial periods before converting to a fully amortizing loan. At September 30, 2019 and December 31, 2018 , interest only loans totaled $588.6 million and $753.1 million , respectively. At September 30, 2019 and December 31, 2018 , $827 thousand and $0 , respectively, of the interest only loans were non-performing. Loans with the Potential for Negative Amortization Negative amortization loans totaled $3.1 million and $3.5 million at September 30, 2019 and December 31, 2018 , respectively. The Company discontinued origination of negative amortization loans in 2007. At September 30, 2019 and December 31, 2018 , none of the loans with the potential for negative amortization were non-performing. These loans pose a potentially higher credit risk because of the lack of principal amortization and potential for negative amortization; however, management believes the credit risk associated with these loans is mitigated through the loan terms and underwriting standards, including the Company’s policies on LTV ratios. Allowance for Loan Losses The Company has 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 and lessees 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 or lease on non-accrual status, assessing the need for additional ALLL, and partial or full charge off the principal balance. The Company maintains the ALLL at a level that is considered adequate to cover the estimated incurred losses in the loan portfolio. The Company also maintains a separate reserve for unfunded loan commitments at a level that is considered adequate to cover the estimated incurred loss. 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 September 30, 2019 and December 31, 2018 , the reserve for unfunded loan commitments was $4.4 million and $4.6 million , respectively, which are included in Accrued expenses and Other liabilities on the Consolidated Statements of Financial Condition. The credit risk monitoring system is designed to identify impaired and potential problem loans, and to perform periodic evaluation of impairment and the adequacy of the allowance for credit losses in a timely manner. In addition, the Board of Directors of the Bank has adopted a credit policy that includes a credit review and control system that it believes should be effective in ensuring that the Company maintains an adequate allowance for loan losses. The Board of Directors also provides oversight and guidance for management’s allowance evaluation process. The following table presents a summary of activity in the ALLL for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, ($ in thousands) 2019 2018 2019 2018 Balance at beginning of period $ 59,523 $ 56,678 $ 62,192 $ 49,333 Loans charged off (35,546 ) (388 ) (39,060 ) (15,977 ) Recoveries of loans previously charged off 410 82 730 864 Net charge-offs (35,136 ) (306 ) (38,330 ) (15,113 ) Provision for loan losses 38,540 1,410 39,065 23,562 Balance at end of period $ 62,927 $ 57,782 $ 62,927 $ 57,782 During the three months ended September 30, 2019, the Company recorded a $35.1 million charge-off of a line of credit originated in November 2017 to a borrower purportedly the subject of a fraudulent scheme. In addition, the charge-off increased the loss factor used in our allowance for loan loss for commercial and industrial loans, resulting in an additional loan loss provision of $3.0 million . On October 22, 2019, in connection with this matter, the Bank filed a complaint in 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. 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, the Company undertook an extensive collateral review of all commercial lending relationships $5 million and above not secured by real estate, consisting of 53 loans representing $536 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 have not identified 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. During the three months ended March 31, 2018, the Company recorded a charge-off of $13.9 million , which reflected the outstanding balance under a $15.0 million line of credit that was originated during the three months ended March 31, 2018.

Troubled Debt Restructurings A modification of a loan constitutes a troubled debt restructuring (TDR) when the Company, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider. The concessions may be granted in various forms, including reduction in the stated interest rate, reduction in the amount of principal amortization, forgiveness of a portion of the loan balance or accrued interest, or extension of the maturity date. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed 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 the Company’s internal underwriting policy.

Accruing TDRs were $6.8 million and non-accrual TDRs were $14.6 million at September 30, 2019 compared to accruing TDRs of $5.7 million and non-accrual TDRs of $2.3 million at December 31, 2018 . The increase in TDRs during the three months ended September 30, 2019 was primarily due to one commercial and industrial relationship.

The Company performs historical loss analysis that is combined with a comprehensive loan or lease to value analysis to analyze the associated risks in the current loan and lease portfolio. The Company analyzes 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. The Company uses 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 the Company’s credit position at some future date. Substandard : Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company 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.

Certain loans are transferred from held-for-investment to held-for-sale at the lower of cost or fair value and any reductions in value on transfer are reflected as write-downs to allowance for loan losses. The Company had no purchases of loans, excluding loans held-for-sale, for the three and nine months ended September 30, 2019 and 2018 .

The loans included in the securitization had a weighted average coupon of 3.79% and a weighted average term to initial reset of 3.5 years . The related mortgage servicing rights were also sold. In connection with the securitization, during the second quarter of 2019 , the Company entered into interest rate swap agreements with a combined notional value of $543.4 million to offset variability in the fair value of the related loans as a result of changes in market interest rates. During the three and nine months ended September 30, 2019 , the Company recognized a gain of $603 thousand and loss of $9.0 million , respectively, related to these swap agreements. The $9.0 million loss on these interest rate swap agreements 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 during the third quarter of 2019. During the three and nine months ended September 30, 2019 , the Company sold $144 thousand and $374.8 million , respectively, in single family residential loans, resulting in a (loss) gain of $(150) thousand and $1.6 million , respectively. During the three and nine months ended September 30, 2019 , the Company sold $573.5 million and $751.6 million , respectively, in multifamily residential loans, resulting in a gross gain of $8.9 million and $11.7 million , respectively.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES For the three and nine months ended September 30, 2019 income tax (benefit) expense, on a consolidated operations basis, was $(5.6) million and $1.4 million , respectively, and the effective tax rate was 28.4% and 12.9% , respectively. For the three and nine months ended September 30, 2018 income tax expense (benefit), on a consolidated operations basis, was $3.6 million and $(102) thousand , respectively, and the effective tax rate was 24.3% and (0.3)% , respectively. During 2019, the Company had a reduction in the recognition of year-to-date tax credits from the investments in alternative energy partnerships of $412 thousand and $9.6 million for the three and nine months ended September 30, 2018 , respectively, compared to $0.9 million and $2.6 million , respectively, of tax credits recognized for the three and nine months ended September 30, 2019 , respectively. The Company uses the flow-through income statement method to account for the investment tax credits earned on the solar investments. Under this method, investment tax credits are recognized as a reduction to income tax expense and the initial book-tax difference in the basis of the investments are recognized as additional tax expense in the year they are earned. The Company accounts 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 the reversal of its taxable temporary differences, the existence of its historical earnings, the amounts of future projected earnings as well as the tax expiration periods of its income tax credits. 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 net deferred tax assets of $46.0 million and $49.4 million at September 30, 2019 and December 31, 2018 , respectively. The overall decrease in net deferred tax assets was primarily due to increases of $2.0 million in deferred tax liabilities resulting from year-to-date temporary book-tax differences and an increase of $6.1 million in deferred tax liabilities from the decrease of unrealized loss on securities available-for-sale, as well as a $4.6 million reclass of tax credit to deferred tax assets. 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. The Company had unrecognized tax benefits of $1.3 million and $1.2 million at September 30, 2019 and December 31, 2018 , respectively. The Company does not expect the total amount of unrecognized tax benefits to significantly change in the next twelve months. As of September 30, 2019 , the total unrecognized tax benefit that, if recognized, would impact the effective tax rate was $1.1 million . At September 30, 2019 and December 31, 2018 , the Company had no accrued interest or penalties. In the event the Company is 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. The Company and its subsidiaries are subject to U.S. Federal income tax as well as income tax in multiple state jurisdictions. The Company is no longer subject to the assessment of U.S. federal income tax for years before 2015. 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

DERIVATIVE INSTRUMENTS	9 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS The Company uses derivative instruments and other risk management techniques to reduce its exposure to adverse fluctuations in interest rates in accordance with its risk management policies. Interest Rate Swaps and Caps on Loans: The Company offers interest rate swap and cap products to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. When such products are issued, the Company also enters into an offsetting swap with institutional counterparties to eliminate the interest rate risk. These back-to-back derivative agreements, which generate fee income for the Company, are intended to offset each other. The Company retains the credit risk of the original loan. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer plus the fee. These swaps and caps are not designated as accounting hedges and are recorded at fair value in Other Assets and Accrued Expenses and Other Liabilities in the Consolidated Statements of Financial Condition. The changes in fair value are recorded in Other Income in the Consolidated Statements of Operations. For the three and nine months ended September 30, 2018 , changes in fair value recorded through Other Income in the Consolidated Statements of Operations were immaterial. For the three and nine months ended September 30, 2019 , other income also includes 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 unrealized 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. Interest Rate Swaps and Caps on Mortgage-backed Securities: During the third quarter, the Company partially hedged the fair value of the MBS portfolio using interest rate swaps. At the end of the quarter, the Company took advantage of the decline in long term interest rates and sold the majority of the MBS portfolio and unwound the majority of the interest rate swaps. The remaining balance of the MBS portfolio and the related interest rate swap is expected to be sold and unwound in the fourth quarter 2019. The unsold portion of the MBS portfolio has been deemed other–than–temporarily impaired and, along with the fair value adjustment on the swap, has been recorded as a loss in noninterest income with a net impact of $731 thousand and is included in the carrying value of MBS. Foreign Exchange Contracts: The Company offers short-term foreign exchange contracts to its customers to purchase and/or sell foreign currencies at set rates in the future. These products allow customers to hedge the foreign exchange rate risk of their deposits and loans denominated in foreign currencies. In conjunction with these products the Company also enters into offsetting contracts with institutional counterparties to hedge the Company’s foreign exchange rate risk. These back-to-back contracts allow the Company to offer its customers foreign exchange products while minimizing its exposure to foreign exchange rate fluctuations. These foreign exchange contracts are not designated as hedging instruments and are recorded at fair value in Other Assets and Accrued Expenses and Other Liabilities on the Consolidated Statements of Financial Condition. For the three and nine months ended September 30, 2019 and 2018 , changes in fair value recorded through Other Income in the Consolidated Statements of Operations were immaterial. The following table presents the notional amount and fair value of derivative instruments included in the Consolidated Statements of Financial Condition as of the dates indicated. September 30, 2019 December 31, 2018 ($ in thousands) Notional Amount Fair Value(1) Notional Amount Fair Value(1) Derivative assets: Interest rate swaps and caps on loans $ 101,253 $ 4,773 $ 103,812 $ 1,534 Foreign exchange contracts 494 36 — — Total $ 101,747 $ 4,809 $ 103,812 $ 1,534 Derivative liabilities: Interest rate swaps and caps on loans $ 101,253 $ 5,198 $ 103,812 1,600 Interest rate swaps on mortgage-backed securities 14,469 325 — — Foreign exchange contracts 494 30 — — Total $ 116,216 $ 5,553 $ 103,812 $ 1,600 (1) The fair value of interest rate swaps and cap on loans are included in other assets and accrued expenses and other liabilities, respectively, in the accompanying consolidated balance sheets. The fair value of interest rate swaps on mortgage-backed securities are include in the carrying value of mortgage-backed securities in the accompanying consolidated balance sheets. The Company has 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. However, the Company elected to account for all derivatives with counterparty institutions on a gross basis. Due to clearinghouse rule changes, variation margin payments are treated as settlements of derivative exposure rather than as collateral.

Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY Warrants On November 1, 2010 , the Company issued warrants to COR Advisors LLC (COR Advisors), an entity controlled by Steven A. Sugarman, who became a director of the Company on that date and later became President and Chief Executive Officer of the Company (and resigned from those and all other positions with the Company and the Bank on January 23, 2017). The warrants entitled COR Advisors to purchase up to 1,395,000 shares of non-voting common stock at an exercise price of $11.00 per share, subject to certain adjustments to the number of shares underlying the warrants as well as certain adjustments to the warrant exercise price as applicable. On August 3, 2011, COR Advisors transferred warrants for the right to purchase 960,000 shares of non-voting common stock to COR Capital Holdings LLC (COR Capital Holdings), an entity controlled by Steven A. Sugarman, and transferred warrants for the right to purchase the remaining 435,000 shares of non-voting common stock to Jeffrey T. Seabold, the Company's then- (now former) Executive Vice President and Management Vice-Chair. On August 22, 2012, COR Capital Holdings transferred its warrants for the right to purchase 960,000 shares of non-voting common stock to a living trust for Steven A. Sugarman and his spouse. These warrants vested in tranches, with each tranche being exercisable for 5 years after the tranche's vesting date. With respect to the warrants transferred by COR Capital Holdings to the living trust for Steven A. Sugarman and his spouse, warrants to purchase 50,000 shares vested on October 1, 2011 and the remainder vested in seven equal quarterly installments beginning January 1, 2012 and ending on July 1, 2013. With respect to the warrants transferred by COR Advisors to Mr. Seabold, warrants to purchase 95,000 shares vested on January 1, 2011; warrants to acquire 130,000 shares vested on each of April 1 and July 1, 2011, and warrants to purchase 80,000 shares vested on October 1, 2011. On August 17, 2016, the living trust for Steven A. Sugarman and his spouse transferred warrants to purchase 480,000 shares to Steven A. Sugarman's brother, Jason Sugarman. These transferred warrants were last exercisable on September 30, 2016, December 31, 2016, March 31, 2017, June 30, 2017 and September 30, 2017 for 50,000 , 130,000 , 130,000 , 130,000 , and 40,000 shares, respectively. On August 17, 2016, Jason Sugarman irrevocably elected to fully exercise each tranche of the transferred warrants. Under his irrevocable election, Jason Sugarman directed that each such exercise would occur on the last exercisable date for each tranche using a cashless (net) exercise method and also directed that each exercise be for either non-voting common stock, or, if allowed under the terms of the warrant, for voting common stock. At September 30, 2016, December 31, 2016, March 31, 2017, June 30, 2017 and September 30, 2017, in accordance with Jason Sugarman’s irrevocable election, warrants to purchase 50,000 , 130,000 , 130,000 , 130,000 , and 40,000 shares, respectively, had been exercised, resulting in issuances of 25,051 and 64,962 shares of the Company's voting common stock and 75,875 , 77,376 and 23,237 shares of the Company's non-voting common stock, respectively. Based on automatic adjustments to the original $11.00 exercise price, the exercise price at the time of exercise was $8.80 , $8.72 , $8.66 , $8.61 and $8.55 per share, respectively. As a result of these exercises, Jason Sugarman no longer holds any warrants to purchase shares of the Company’s stock. During the three months ended June 30, 2018, based on additional documentation received from Jason Sugarman, it was determined that Jason Sugarman was eligible to receive voting common stock under the terms of the transferred warrant for the exercises that previously occurred on March 31, 2017, June 30, 2017 and September 30, 2017. Accordingly, on June 6, 2018, an aggregate of 176,488 shares of the Company's non-voting common stock owned by Jason Sugarman were canceled and he was issued 176,488 shares of the Company's voting common stock in lieu thereof. On August 16, 2016, the living trust for Steven A. Sugarman and his spouse irrevocably elected to exercise its warrants to purchase 480,000 shares. Under its irrevocable election, the living trust for Steven A. Sugarman and his spouse directed that each such exercise would occur on the last exercisable date for each tranche of such warrants (September 30, 2017, December 31, 2017, March 31, 2018 and June 30, 2018 with respect to 90,000 , 130,000 , 130,000 , and 130,000 shares, respectively) using a cashless net exercise method and also directed that each exercise be for non-voting common stock.

On each of December 27, 2017, March 30, 2018 and June 29, 2018, the Company was notified that the living trust for Steven A. Sugarman and his spouse purportedly transferred warrants with respect to 130,000 shares, with a last exercisable date of December 31, 2017, 130,000 shares with a last exercisable date of March 31, 2018 and 130,000 shares with a last exercisable date of June 30, 2018, respectively, to a separate entity, Sugarman Family Partners.

Based on an automatic adjustment to the original $11.00 exercise price, the exercise price at the time of exercise was $8.49 per share, $8.44 per share and $8.38 per share, respectively. As a result of these exercises, none of these warrants remain outstanding. On December 8, 2015, March 9, 2016, June 17, 2016, and September 30, 2016, Mr. Seabold exercised his warrants with respect to 95,000 , 130,000 , 130,000 , and 80,000 shares, respectively, using cashless (net) exercises, resulting in a net number of shares of non-voting common stock issued in the aggregate of 37,355 , 53,711 , 70,775 , and 40,081 , respectively. Based on automatic adjustments to the original $11.00 exercise price, the exercise price at the time of exercise was $9.04 , $8.90 , $8.84 , and $8.80 per share, respectively. As a result of these exercises, Mr. Seabold no longer holds any warrants to purchase shares of the Company's stock. Under the terms of the respective warrants, the warrants were exercisable for voting common stock in lieu of non-voting common stock following a transfer of the warrants under certain circumstances described in the terms of the warrants. The terms and issuance of the foregoing warrants were approved by the Company's stockholders at a special meeting held on October 25, 2010. Preferred Stock The Company is authorized to issue 50,000,000 shares of preferred stock with par value of $0.01 per share. Preferred shares outstanding rank senior to common shares both as to dividends and liquidation preference but generally have no voting rights. All of the Company's outstanding shares of preferred stock have a $1,000 per share liquidation preference. The following table presents the Company's total outstanding preferred stock as of dates indicated: September 30, 2019 December 31, 2018 ($ in thousands) Shares Outstanding Liquidation Preference Carrying Value Shares Outstanding Liquidation Preference Carrying Value Series D 7.375% non-cumulative perpetual 96,629 $ 96,629 $ 93,162 115,000 $ 115,000 $ 110,873 Series E 7.00% non-cumulative perpetual 100,477 100,477 96,663 125,000 125,000 120,255 Total 197,106 $ 197,106 $ 189,825 240,000 $ 240,000 $ 231,128 On September 17, 2018, the Company completed the redemption of all 40,250 outstanding shares of the Company's 8.00 percent Series C Non-Cumulative Perpetual Preferred Stock (Series C Preferred Stock), which resulted in the simultaneous redemption of all 1,610,000 of the outstanding related depositary shares (Series C Depository Shares), each representing a 1/40 th interest in a share of Series C Preferred Stock, at a redemption price of the liquidation amount of $1,000 per share of Series C Preferred Stock (equivalent to $25 per Series C Depository Share). The redemption price represented an aggregate amount of $40.3 million and did not accrue interest from and following the regularly scheduled dividend payment date of September 15, 2018. Deferred stock issuance costs of $2.3 million originally recorded as a reduction to preferred stock upon issuance of the Series C Preferred Stock were reclassified to retained earnings and resulted in a non-cash reduction to net income allocated to common stockholders. On August 23, 2019, the Company completed a tender offer for 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 734,823 outstanding Series D Depository Shares and the related retirement of 18,371 outstanding shares of Series D Preferred Stock. The repurchase price aggregated to $19.4 million . The $1.7 million difference between the consideration paid and the carrying value of the Series D Preferred Stock was reclassified to retained earnings and resulted in a non-cash reduction to net income allocated to common stockholders. On August 23, 2019, the Company completed a tender offer for 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 980,928 outstanding Series E Depository Shares and the related retirement of 24,523 outstanding shares of Series E Preferred Stock. The repurchase price aggregated $26.6 million .

VARIABLE INTEREST ENTITIES

VARIABLE INTEREST ENTITIES	9 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES T he Company holds ownership interests in alternative energy partnerships and qualified affordable housing partnerships and has a variable interest in a multifamily securitization trust. The Company evaluates its interests in these entities to determine whether they meet the definition of a variable interest entity (VIE) and whether the Company is 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 the Company holds could potentially be significant to the VIE, the Company considers both qualitative and quantitative factors regarding the nature, size and form of the Company's involvement with the VIE. The Company has determined that its interests in these entities meet the definition of variable interests. Unconsolidated VIEs Multifamily Securitization During the third quarter of 2019, the Company 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. The Company determined that it is not the primary beneficiary of this VIE as it does 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, the Company has 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 the Company in the event that all of the assets in the securitization trust are deemed worthless is $68.8 million , which represents the aforementioned Company’s obligation to guarantee credit losses up to 12 percent . The Company believes 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 September 30, 2019 , the Company has recognized a $4.4 million repurchase liability related to this VIE. Alternative Energy Partnerships The Company invests 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 either newly installed residential rooftop solar leases and power purchase agreements or newly installed ground mount solar power purchase agreements. As a result of its investments, the Company has 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 customers for a fixed period of time. While the Company's interest in the alternative energy partnerships meets the definition of a VIE in accordance with ASC 810, the Company has determined that the Company is not the primary beneficiary because the Company does 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 the Company is not the primary beneficiary, the Company did not consolidate the entities. The Company uses 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 the Company’s 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, the Company uses 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. During the three and nine months ended September 30, 2019 , the Company funded zero and $235 thousand for its alternative energy partnerships and did not receive any return of capital from its alternative energy partnerships. During the three months ended September 30, 2018 , the Company received a return of capital of zero and funded zero , respectively, from and into these partnerships. During the nine months ended September 30, 2018, the Company received a return of capital of $1.0 million and funded zero , respectively, from and into these partnerships. During the three months ended September 30, 2019 and 2018 , the Company recognized a (gain) loss on investment of $(0.9) million and $2.5 million , respectively, through its HLBV application. During the nine months ended September 30, 2019 and 2018 , the Company recognized a loss on investment of $0.7 million and $4.3 million , respectively, through its HLBV application. As a result, the balance of these investments was $27.0 million and $41.8 million at September 30, 2019 and 2018 , respectively. From an income tax benefit perspective, the Company recognized investment tax credits of $862 thousand and $412 thousand for the three months ended September 30, 2019 and 2018 , respectively, and $2.6 million and $9.6 million during the nine months ended September 30, 2019 and 2018 , respectively, as well as income tax benefits (expense) relating to the recognition of its loss (gain) through its HLBV application during these periods. The following table represents the carrying value of the associated unconsolidated assets and liabilities and the associated maximum loss exposure for alternative energy partnerships as of the dates indicated: ($ in thousands) September 30, December 31, Cash $ 3,871 $ 3,012 Equipment, net of depreciation 250,892 259,464 Other assets 5,728 4,470 Total unconsolidated assets $ 260,491 $ 266,946 Total unconsolidated liabilities $ 6,692 $ 6,269 Maximum loss exposure $ 30,835 $ 28,988 The maximum loss exposure that would be absorbed by the Company in the event that all of the assets in alternative energy partnerships are deemed worthless is $30.8 million , which is the Company's recorded investment amount and remaining unfunded commitment at September 30, 2019 . The Company believes that the loss exposure on its investment is reduced considering that the return on its investment is provided not only by the cash flows of the underlying customer leases and power purchase agreements, but also through the significant tax benefits, including federal tax credits generated from the investments. In addition, the management 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 the Company’s exposure. Qualified Affordable Housing Partnerships The Company also invests 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 the Company's 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, the Company is 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, the Company does not consolidate these partnerships. At September 30, 2019 and December 31, 2018 , the Company had a total investment in qualified affordable housing projects of $37.3 million and $20.0 million , respectively. During the three and nine months ended September 30, 2019 , the Company funded $8.3 million and $8.8 million , respectively, and recognized proportional amortization expense of $1.5 million and $2.7 million , respectively. The Company has funded $26.5 million of its $49.3 million aggregated funding commitments and had an unfunded commitment of $22.7 million at September 30, 2019 . During the three and nine months ended September 30, 2018 , the Company funded $384 thousand and $2.0 million , respectively, into qualified affordable housing projects and recognized proportional amortization expense of $498 thousand and $1.5 million , respectively. From an income tax benefit perspective, the Company recognized investment tax credits of $724 thousand and $470 thousand , respectively, during the three months ended September 30, 2019 and 2018 and $1.8 million and $1.4 million for the nine months ended September 30, 2019 and 2018 , respectively. At September 30, 2019 and December 31, 2018 , the maximum loss exposure that would be absorbed by the Company in the event that all of the assets in this investment are deemed worthless is $37.3 million and $20.0 million , respectively, which is the Company's recorded investment amount. The recorded investment amount is included in Other Assets in the Consolidated Statements of Financial Condition and the proportional amortization expense is recorded in Income Tax Expense (Benefit) in the Consolidated Statements of Operations. As the investments in alternative energy partnerships and qualified affordable housing partnerships represent unconsolidated VIEs to the Company, the assets and liabilities of the investments themselves are not recorded on the Company's Statements of Financial Condition.

On September 5, 2017, John A. Bogler became the Chief Financial Officer of the Company and the Bank. Mr. Bogler is a founding member, and since 2015 and up until his employment with the Company, was a board member and Chief Financial Officer, of Sabal Capital Partners, LLC and Sabal Investment Advisors, LLC. Sabal Capital Partners, LLC is the sole owner of Sabal Opportunities Fund I, LLC, which in turn is the sole owner of Sabal TL1, LLC; Sabal Investment Advisors, LLC is the investment manager of SIA Debt Opportunities Fund, LP. SDOF GP, LLC is the general partner of Sabal Investment Advisors, LLC (together, Sabal). As of September 1, 2018, Mr. Bogler had completely divested his ownership in Sabal, except for an investment in SDOF GP, LLC that represents only a right of Mr. Bogler to receive his pro-rata share of pass through distributions (net of expenses) by SIA Debt Opportunities Fund, LP with respect to underlying investments that were made by the fund. Effective June 26, 2015, the Bank provided a $35.0 million committed revolving repurchase facility, which was increased to $40.0 million effective June 11, 2017, to Sabal TL1, LLC, with a maximum funding amount of $100.0 million in certain situations. On June 6, 2018, the revolving repurchase facility was extended for 90 days beyond its original maturity date of June 10, 2018. The repurchase facility's outstanding balance was $3.5 million before it was completely paid off in August 2018. The extension was not renewed and expired on September 10, 2018. Under the Sabal repurchase facility, commercial mortgage loans originated by Sabal were purchased from Sabal by the Bank, together with a simultaneous agreement by Sabal to repurchase the commercial mortgage loans from the Bank at a future date. The advances under the Sabal repurchase facility were secured by commercial mortgage loans that had a market value in excess of the balance of the advances under the facility. During the year ended December 31, 2018 , the largest aggregate amount of principal outstanding under the Sabal repurchase facility was $32.5 million . The Sabal repurchase facility was paid off during the year ended December 31, 2018 .

Commitments and Contingencies Disclosure [Abstract]
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, the Company establishes an accrued liability when those matters present loss contingencies that are both probable and estimable. The Company continues to monitor the matters for further developments that could affect the amount of the accrued liability that has been previously established. As of September 30, 2019 , the Company accrued $20.3 million for various litigation filed against the Company and the Bank, including an accrual for $19.75 million related to the settlement of the securities litigation previously announced by the Company 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 the Company's insurance carriers and the Company has recorded an insurance receivable for $19.75 million related to this matter. On September 16, 2019, the Company entered into a Memorandum of Understanding (“MOU”) 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 MOU, the Company’s insurance carriers would pay $19.75 million , which would be distributed to shareholders who purchased Company stock between April 15, 2016 and January 20, 2017, after payment of attorney’s fees and costs, to be determined by the Court. The Company would not be required to contribute any cash to the settlement payments. Pursuant to the settlement, the action against the Company would be dismissed with prejudice. Plaintiff would also dismiss its claims against the Company’s former Chief Executive Officer and Chairman Steven Sugarman. While the Company does not believe the plaintiff’s claims are meritorious, the Company believes that ending the costs and distraction of the litigation is in the best interests of the Company and its shareholders. The settlement and the dismissals are subject to approval by the Court and meeting certain conditions, and there are no assurances that Court approval will be obtained or that those conditions will be satisfied. If the Court preliminarily approves the settlement, members of the class will be provided notice and an opportunity to object or opt out. Following the notice and opportunity for objections and opt outs, the Court will schedule a fairness hearing at which the Court will determine whether the settlement shall be finally approved. 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 will be filed with the Court.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2019
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, 2018 filed by the Company with the SEC. The December 31, 2018 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, 2018 filed with the SEC, but does not include all of the disclosures required by GAAP for complete financial statements.
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, 2019 and December 31, 2018 and for the three and nine months ended September 30, 2019 and 2018 . 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.
Accounting Pronouncements	Adopted Accounting Pronouncements: During the nine months ended September 30, 2019 , the following pronouncements applicable to the Company were adopted: In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (ASU) 2016-02 Topic 842, “Leases” which increases transparency and comparability among organizations by requiring the recognition of right of use (ROU) assets and lease liabilities on the balance sheet. Most prominent among the changes in the standard is the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases. Under the standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company adopted Topic 842 and related updates effective January 1, 2019 and used the effective date as the date of initial application, and therefore, periods prior to January 1, 2019 were not restated. The Company elected the package of practical expedients, which permits us not to reassess prior conclusions about lease identifications, lease classification and initial direct costs under the new standard. The Company did not elect to apply the hindsight practical expedient pertaining to using hindsight knowledge as of the effective date when determining lease terms and impairment. The Company also has elected the short-term lease recognition exemption (leases with terms 12 months or less) for all leases that qualify, and thus will not recognize ROU assets or lease liabilities for those leases. In addition, the Company elected the practical expedient to not separate lease and non-lease components for all of our leases. Upon adoption, the Company recognized on its consolidated balance sheet ROU assets of approximately $23.3 million (inclusive of an adjustment to remove the Company's existing deferred rent liability of approximately $1.4 million ) with a corresponding operating lease liability of approximately $24.7 million . The standard did not have an impact on our consolidated statements of operations. In addition, the Company's accounting for finance leases remained substantially unchanged. In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment," which amended ASC 350 "Intangibles-Goodwill and Other." The amendments in this ASU simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. ASU 2017-04 is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company has early adopted this guidance prospectively as of August 31, 2019, and the adoption did not have a material impact on our financial statements. Significant Accounting Policies: The accounting and reporting policies of the Company are based upon GAAP and conform to predominant practices within the banking industry. The Company has not made any significant changes in its critical accounting policies from those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC, except for the accounting for leases as described below. Leases. The Company determines if an arrangement is a lease at inception. The Company’s operating lease agreements are primarily for real estate space and are included within right of use (ROU) assets and lease liabilities on the September 30, 2019 consolidated balance sheet. The ROU asset is based on the operating lease liabilities adjusted for any prepaid or deferred rent. The Company has elected not to recognize on its consolidated balance sheet leases with terms of one-year or less. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, the Company uses its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment, at lease commencement date in determining the present value of lease payments. Many of the Company’s lessee agreements include options to extend the lease, which the Company does not include in its minimum lease terms unless they are reasonably certain to be exercised. The Company elected the practical expedient to combine its lease and related nonlease components for the Company’s building leases. Rental expense for lease payments related to operating leases is recognized on a straight-line basis over the lease term
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 allowance for loan losses (ALLL), 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.
Discontinued Operations	Discontinued Operations: During the three months ended March 31, 2017, the Company completed the sale of its Banc Home Loans division, which largely represented the Company's Mortgage Banking segment. In accordance with Accounting Standards Codification (ASC) 205-20, the Company determined that the sale of the Banc Home Loans division and certain other mortgage banking related assets and liabilities that would be sold or settled separately within one year met the criteria to be classified as a discontinued operation and the related operating results and financial condition have been presented as discontinued operations on the consolidated financial statements. See Note 2 for additional information. Unless otherwise indicated, information included in these notes to the consolidated financial statements is presented on a consolidated operations basis, which includes results from both continuing and discontinued operations, as of December 31, 2018 and for the three and nine months ended September 30, 2018
