SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	6 Months Ended
	Jun. 30, 2023
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations: Banc of California, Inc., a Maryland corporation, was incorporated in March 2002 and serves as the holding company for its wholly owned subsidiary, Banc of California, National Association (the “Bank”), a California-based bank. When we refer to the “parent” or the “holding company", we are referring to Banc of California, Inc., the parent company, on a stand-alone basis. When we refer to “we,” “us,” “our,” or the “Company”, we are referring to Banc of California, Inc. and its consolidated subsidiaries including the Bank, collectively. We are regulated as a bank holding company by the FRB and the Bank operates under a national bank charter issued by the 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 33 offices including 27 full-service branches located throughout Southern California as of June 30, 2023. 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, 2022 filed by us with the SEC. Certain prior period amounts have been reclassified to conform to current period presentation. These reclassifications are immaterial and have no effect on net income, comprehensive income (loss), total assets or total shareholders’ equity previously reported. 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 six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. Principles of Consolidation: The accompanying unaudited consolidated financial statements include the accounts of the Company and its consolidated subsidiaries as of June 30, 2023 and December 31, 2022 and for the three and six months ended June 30, 2023 and June 30, 2022. 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. We have not made any changes in our significant accounting policies from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC, except for those described below, which reflect a new accounting policy adopted and the impact of the adoption of ASU 2022-02: Derivative Instruments - Cash Flow Hedge : The Company applies hedge accounting for certain derivative instruments used to manage interest rate risk. A cash flow hedge is a derivative instrument used to manage the variability in future expected cash flows that would otherwise be impacted by movements in interest rates. To quality for hedge accounting, the cash flow hedge must be highly effective at reducing the risk associated with the hedged exposure. The effectiveness of the hedging relationship is documented at inception and is monitored at least quarterly through the life of the transaction. A cash flow hedge that is designated as highly effective is carried at fair value with the change in fair value included in the assessment of hedge effectiveness recorded in other comprehensive income (loss) (“AOCI”) and subsequently recognized in earnings in the same period that the hedged forecasted transaction affects earnings. At that time, the amount reclassified from AOCI is presented in the same income statement line item in which the hedged transaction is reported (interest income or expense). If the cash flow hedge becomes ineffective, the change in fair value is reclassified from AOCI to earnings. Loan Modifications to Borrowers Experiencing Financial Difficulty: Prior to the adoption of ASU 2022-02, we accounted for the modification to the contractual terms of a loan that resulted in granting a concession to a borrower experiencing financial difficulties as a troubled debt restructuring (“TDR”). Effective January 1, 2023, we adopted ASU 2022-02, which eliminated TDR accounting prospectively for all restructurings occurring on or after January 1, 2023. Loans that were considered a TDR prior to the adoption of ASU 2022-02 will continue to be accounted for under the superseded TDR accounting guidance until the loan is paid off, liquidated, or subsequently modified. Since adoption of ASU 2022-02 on January 1, 2023, we have evaluated all loan modifications under ASC 310-20 to determine whether a modification made to a borrower results in a new loan or is a continuation of the existing loan. 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 credit losses (“ACL”) (which includes the allowance for loan losses (“ALL”) and the reserve for unfunded noncancellable loan commitments (“RUC”)), loan repurchase reserve, realization of deferred tax assets, the fair value of assets and liabilities acquired in business combinations and related purchase price allocation, the valuation of goodwill and other intangible assets, other derivatives, 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. Recently Adopted Accounting Guidance: In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-02, Financial Instruments—Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures , which addresses areas identified by the FASB as part of its post-implementation review of the credit losses standard (“ASU 2016-13”) that introduced the current expected credit losses (“CECL”) model. The amendments eliminate the accounting guidance for TDRs by creditors that have adopted the CECL model and enhances the disclosure requirements for loan refinancings and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require a public business entity to disclose current-period gross write-offs for financing receivables by year of origination in the vintage disclosures. ASU 2022-02 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. We adopted ASU 2022-02 on January 1, 2023 and the impact of adoption did not have a material effect on our consolidated financial statements. Recently Issued Accounting Guidance Not Yet Adopted : In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force) (“ASU 2023-02”) , which permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method, which was previously allowed only for low-income housing tax credit (“LIHTC”) investments, if certain conditions are met. ASU 2023-02 is effective for fiscal years beginning after December 15, 2023, and including interim periods within those fiscal years. The amendment must be applied on either a modified retrospective or a retrospective basis, and early adoption is permitted. The Company is currently evaluating the impact of this update on its consolidated financial statements and related disclosures, including assessing eligibility to apply the updated guidance to our investments in alternative energy partnerships currently accounted for using the HLBV method of the equity method of accounting.

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 (“AFS”): The fair values of AFS securities 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 (Level 2). We adhere to established processes to monitor the pricing services’ assumptions and challenge the valuations that appear unusual or unexpected. Multiple quotes or prices may be obtained in this process and we determine which fair value is most appropriate based on market information and analysis. Quotes obtained through this process are generally non-binding. We follow established procedures to ensure that assets and liabilities are properly classified in the fair value hierarchy. Level 2 securities include SBA loan pool securities, U.S. government agency and U.S. government sponsored enterprise residential mortgage-backed securities, non-agency residential mortgage-backed securities, non-agency commercial mortgage-backed securities, collateralized loan obligations, and corporate debt securities. When a market is illiquid or there is a lack of transparency around the inputs to valuation, including at least one unobservable input, the securities are classified as Level 3 and reliance is placed upon internally developed models and management’s judgment and evaluation for valuation. Derivative Assets and Liabilities: Cash Flow Hedge. We have entered into pay-fixed, receive-variable interest rate swap contracts with institutional counterparties to hedge against variability in cash flows attributable to interest rate risk caused by changes in interest rates on our deposits and borrowings. We estimate the fair value of these contracts based on inputs from a third-party pricing model, which incorporates such factors as the Treasury curve, SOFR rates, and the pay rate on the interest rate swaps. 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. Interest Rate Swaps. We offer interest rate swap products to certain loan clients to allow them to hedge the risk of rising interest rates on their variable rate loans. We originate a variable rate loan and enter into a variable-to-fixed interest rate swap with the client. We also enter into an offsetting swap with a correspondent bank. These back-to-back agreements are intended to offset each other and allow us to originate a variable rate loan while providing a contract for fixed interest payments for the client. The net cash flow for us is equal to the interest income received from a variable rate loan originated with the client plus a fee. The fair value of these derivatives is based on a discounted cash flow approach. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of interest rate swaps is classified as Level 2. Foreign Exchange Contracts. We offer short-term foreign exchange contracts to customers to purchase and/or sell foreign currencies at set rates in the future. These products allow customers to hedge the foreign exchange rate risk of their deposits and loans denominated in foreign currencies. In conjunction with these products, we also enter into offsetting back-to-back contracts with institutional counterparties to hedge our foreign exchange rate risk. These back-to-back contracts are intended to offset each other and allow us to offer our customers foreign exchange products. The fair value of both of these offsetting asset and liability instruments is based on the change in the underlying foreign exchange rate. We are subject to counterparty risk in the event our customers or institutional counterparties default under these contracts. Given the short-term nature of the contracts, the counterparties’ credit risks are considered nominal and typically result in no adjustments to the valuation of the short-term foreign exchange contracts. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of these contracts is classified as Level 2.

There were no assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three and six months ended June 30, 2023 and 2022. Assets and Liabilities Measured on a Non-Recurring Basis Individually Evaluated Loans: The fair value of individually evaluated loans with specific allocations of the ACL based on collateral values is generally derived from recent real estate appraisals and automated valuation models (“AVMs”). These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers for differences between the comparable sales and income data available. Such adjustments are typically deemed significant unobservable inputs used for determining fair value and result in a Level 3 classification. Other Real Estate Owned (“OREO”): The fair value of OREO is generally based on recent real estate appraisals, less estimated costs to sell. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers for differences between the comparable sales and income data available. Such adjustments are typically deemed significant unobservable inputs used for determining fair value and result in a Level 3 classification.

At the time of the transfer, the securities had an unrealized gross loss of $16.6 million, which became part of the securities’ amortized cost basis. This amount, along with the unrealized loss included in accumulated other comprehensive income, is subsequently amortized over the remaining life of the security as an adjustment to its yield using the interest method. As a result, there is no impact on the consolidated statements of operations. At June 30, 2023, the gross unrealized loss included in accumulated other comprehensive income was $15.3 million. At June 30, 2023, our investment securities portfolio consisted of agency securities, municipal securities, mortgage-backed securities (“MBS”), collateralized loan obligations (“CLOs”), and corporate debt securities. 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. Accrued interest receivable on AFS and HTM securities totaled $10.4 million and $9.2 million at June 30, 2023 and December 31, 2022, and is included within other assets in the accompanying consolidated statements of financial condition. At June 30, 2023 and December 31, 2022, there were no holdings of any one issuer, other than U.S. government agency and sponsored enterprises, in an amount greater than 10 percent of our stockholders’ equity. Pledged Securities Investment securities with carrying values of $535.1 million and $356.5 million as of June 30, 2023 and December 31, 2022 were pledged to secure FHLB advances, FRB borrowings, public deposits and for other deposits as required or permitted by law.

At December 31, 2022, our AFS securities portfolio consisted of 77 securities, of which 76 securities were in an unrealized loss position. We monitor our securities portfolio for identification of potential credit impairment. During the three and six months ended June 30, 2023, we recognized a $1.0 million provision for credit losses on three corporate debt securities of other financial institutions that were downgraded to below investment grade by external credit agencies. During the three and six months ended June 30, 2022, there was no provision for credit losses related to AFS or HTM securities. Except for the corporate debt securities noted above, we believe there was no credit impairment and the decline in fair value of our securities since acquisition was attributable to a combination of changes in interest rates and general volatility in market conditions. As of June 30, 2023, we did not have the intent to sell securities in an unrealized loss position and further believe, it is more likely than not, that we will not be required to sell these securities before their anticipated recovery. As of June 30, 2023, 82 of our 85 AFS securities in an unrealized loss position received an investment grade credit rating, and all of our HTM securities in an unrealized loss position received an investment grade credit rating.

Credit Quality Indicators We categorize loans into risk categories based on relevant information about the ability of borrowers to repay their debt such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. We analyze the associated risks in the current loan portfolio and individually grade each loan for credit risk. This analysis includes all loans delinquent over 60 days and non-homogeneous loans such as commercial and commercial real estate (“CRE”) loans. We use the following definitions for risk ratings: Pass : Loans risk rated “Pass” are in compliance in all respects with the Bank’s credit policy and regulatory requirements, and do not exhibit any potential or defined weakness as defined under “Special Mention”, “Substandard” or “Doubtful.” Special Mention : Loans risk rated “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 loans or of our credit position at some future date. Substandard : Loans risk rated “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 a weakness that jeopardizes the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Doubtful : Loans risk rated “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 - Loans The ACL methodology uses a nationally recognized, third-party model that includes many assumptions based on historical and peer loss data, current loan portfolio risk profile including risk ratings, and economic forecasts including macroeconomic variables released by the model provider during June 2023. The published forecasts consider the Federal Reserve’s monetary policy, labor market constraints, inflation levels, global oil prices and changes in real estate values, among other factors. The ACL also incorporates qualitative factors to account for certain loan portfolio characteristics that are not taken into consideration by the third-party model including underlying strengths and weaknesses in various segments of the loan portfolio. As is the case with all estimates, the ACL is expected to be impacted in future periods by economic volatility, changing economic forecasts, underlying model assumptions, and asset quality metrics, all of which may be better or worse than current estimates. The ACL process involves subjective and complex judgments as well as adjustments for numerous factors including those described in the federal banking agencies’ joint interagency policy statement on ALL, which include underwriting experience and collateral value changes, among others. The RUC is established to cover the current expected credit losses for the estimated level of funding of these loan commitments, except for unconditionally cancellable commitments for which no reserve is required under ASC 326. At June 30, 2023 and December 31, 2022, the reserve for unfunded loan commitments was $4.0 million and $5.3 million and was included in accrued expenses and other liabilities on the consolidated statements of financial condition.

Troubled Debt Restructurings (for modifications to borrowers experiencing financial difficulty prior to January 1, 2023) At June 30, 2023 and December 31, 2022, we had 10 and 15 loans classified as TDRs, with an aggregate balance of $8.0 million and $16.1 million. During the six months ended June 30, 2023 a $3.9 million commercial and industrial (“C&I”) loan that was restructured during 2022 was modified and accounted for as a new loan. Additionally, $4.0 million relating to two commercial relationships were paid down during this same period. Accruing TDRs were $2.5 million and nonaccrual TDRs were $5.5 million at June 30, 2023, compared to accruing TDRs of $2.7 million and nonaccrual TDRs of $13.4 million at December 31, 2022. Purchases, Sales, and Transfers From time to time, we purchase and sell loans in the secondary market. There were no loans purchased during the three months ended June 30, 2023. During the six months ended June 30, 2023, we purchased loans aggregating $61.4 million. During the three and six months ended June 30, 2022, we purchased loans aggregating $277.2 million and $641.5 million. There were no loans transferred from held for investment to loans held-for-sale, and there were no sales of loans for the three and six months ended June 30, 2023 and 2022. Non-Traditional Mortgage (“NTM”) Loans We no longer originate SFR loans, however we have purchased and may continue to purchase pools of loans that include NTM loans such as interest only loans with maturities of up to 40 years and flexible initial repricing dates, ranging from 1 to 10 years, and periodic repricing dates through the life of the loan. NTM loans are included in our SFR mortgage portfolio and are comprised primarily of interest only loans. As of June 30, 2023 and December 31, 2022, the NTM loans totaled $811.7 million, or 11.3% of total loans, and $862.3 million, or 12.1% of total loans. The total NTM portfolio decreased by $50.7 million, or 5.9% during the six months ended June 30, 2023. The decrease was due to principal paydowns and payoffs. At June 30, 2023 and December 31, 2022, nonperforming NTM loans totaled $13.3 million and $3.0 million. Non-Traditional Mortgage Performance Indicators

GOODWILL AND OTHER INTANGIBLES	GOODWILL AND OTHER INTANGIBLES Goodwill Goodwill represents the excess consideration paid for net assets acquired in a business combination over their fair values. At June 30, 2023 and December 31, 2022, we had goodwill of $114.3 million. The following table presents changes in the carrying amount of goodwill for the periods indicated: Three Months Ended Six Months Ended ($ in thousands) 2023 2022 2023 2022 Goodwill, beginning of period $ 114,312 $ 95,127 $ 114,312 $ 94,301 Goodwill adjustments for purchase accounting — — — 826 Goodwill, end of period $ 114,312 $ 95,127 $ 114,312 $ 95,127 The acquisition of Deepstack in the third quarter of 2022 resulted in the recognition of $18.2 million in goodwill. We also adjusted goodwill in the first quarter of 2022 as a result of updates to the initial fair value of core deposit intangibles and finalization of income tax returns related to the acquisition of PMB. We evaluate goodwill for impairment as of October 1 each year, and more frequently if events or circumstances indicate that there may be impairment. We completed our most recent annual goodwill impairment test as of October 1, 2022 and determined that no goodwill impairment existed. For the three and six months ended June 30, 2023, we analyzed indicators related to potential goodwill impairment due to volatility in the financial markets and recent events in the banking sector. Based on this analysis, we did not identify any impairment to goodwill. Other Intangibles Other intangibles are comprised of the following at June 30, 2023 and December 31, 2022: ($ in thousands) June 30, December 31, Core deposit intangibles $ 3,363 $ 3,932 Developed technology 2,357 2,637 Other intangibles 883 957 Total other intangibles $ 6,603 $ 7,526 Other intangibles are amortized over their estimated useful lives and reviewed for impairment at least quarterly.

As of June 30, 2023, FHLB advances consisted of $611 million in term advances with a weighted average life of 3 years and a weighted average interest rate of 2.91% and $200 million in putable advances with a weighted average life of 4.5 years and a weighted average interest rate of 3.44%. Term advances are payable at maturity date, and advances paid early are subject to a prepayment penalty. The putable advances can be called quarterly until maturity at the option of the FHLB beginning in December 2023. FHLB advances are collateralized by a blanket lien on all real estate loans. As of June 30, 2023, our secured borrowing capacity with the FHLB totaled $2.39 billion, of which the Bank was eligible to borrow an additional $1.16 billion based on qualifying loans with an aggregate unpaid principal balance of $3.47 billion as of that date. The Bank’s investment in the capital stock of the FHLB of San Francisco totaled $25.7 million and $22.6 million at June 30, 2023 and December 31, 2022. Federal Reserve Bank (FRB) Borrowings At June 30, 2023, the Bank had borrowing capacity with the Federal Reserve Bank of San Francisco (the “Federal Reserve”) of $1.45 billion, including the secured borrowing capacity through the FRB Discount Window, Borrower-in-Custody (“BIC”), and Bank Term Funding (“BTFP”) programs. Borrowings under the BIC program are overnight advances with interest chargeable at the primary credit borrowing rate. Borrowings under the BTFP, which was established in March 2023, are for periods up to one year in length, with interest rates based on the one-year overnight index swap (“OIS”) rate plus a spread of 10 basis points. BTFP borrowings are collateralized by eligible investment securities valued at par and provide an additional source of liquidity leveraging high-quality securities. At June 30, 2023, the Bank pledged certain qualifying loans with an unpaid principal balance of $1.40 billion and securities with a carrying value of $515.3 million as collateral for the FRB credit programs. Borrowings from the Federal Reserve through the FRB Discount Window and BIC programs were $340.0 million and zero at June 30, 2023 and December 31, 2022. There were no borrowings under the BTFP at June 30, 2023. The Bank’s investment in capital stock of the Federal Reserve totaled $34.6 million and $34.5 million at June 30, 2023 and December 31, 2022. Other Borrowings The Bank maintained available unsecured federal funds lines with six correspondent banks totaling $290.0 million, with no outstanding borrowings at June 30, 2023 and December 31, 2022. The Bank also has the ability to access unsecured overnight borrowings from various financial institutions through the American Financial Exchange platform ("AFX"). The availability of such unsecured borrowings fluctuates regularly and are subject to the counterparties discretion and totaled $365.0 million and $445.0 million at June 30, 2023 and December 31, 2022. Borrowings from the correspondent banks and AFX totaled zero at June 30, 2023 and December 31, 2022. In December 2022, the holding company renewed its $50.0 million revolving line of credit with another financial institution. The line of credit matures on December 18, 2023 and is subject to certain operational and financial covenants. There were no borrowings under this line of credit at June 30, 2023 and December 31, 2022, and we were in compliance with all covenants. The Bank also maintained repurchase agreements and had no outstanding securities sold under agreements to repurchase at June 30, 2023 and December 31, 2022. Availabilities and terms on repurchase agreements are subject to the counterparties’ discretion and the pledging of additional investment securities.

INCOME TAXES

INCOME TAXES	6 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES For the three and six months ended June 30, 2023, income tax expense was $6.7 million and $14.1 million, resulting in an effective tax rate of 27.4% and 27.0%. For the three and six months ended June 30, 2022, income tax expense was $10.2 million and $28.9 million, resulting in an effective tax rate of 27.6% and 27.8%. The effective tax rate for the three and six months ended June 30, 2023 and 2022, differs from the combined federal and state statutory rate for the consolidated company of 28.9% due primarily to various permanent tax differences, tax credits and other discrete tax items that impact our effective tax rate. We account for income taxes by recognizing deferred tax assets and liabilities based upon temporary differences between the amounts for financial reporting purposes and the tax basis of our assets and liabilities. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In assessing the realization of deferred tax assets, management will continue to evaluate both positive and negative evidence on a quarterly basis, including considering the four possible sources of future taxable income, such as future reversal of existing taxable temporary differences, future taxable income exclusive of reversing temporary differences and carryforwards, taxable income in prior carryback year(s), and future tax planning strategies. Based on this analysis, management determined, it was more likely than not, that all of the deferred tax assets would be realized; therefore, no valuation allowance was provided against the net deferred tax assets of $64.0 million and $50.5 million at June 30, 2023 and December 31, 2022. 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 $0.8 million at both June 30, 2023 and December 31, 2022. We do not believe that the unrecognized tax benefits will change materially in the next twelve months. As of June 30, 2023, the total unrecognized tax benefit that, if recognized, would impact the effective tax rate was $0.6 million. At June 30, 2023 and December 31, 2022, 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 2019. The statute of limitations for the assessment of California franchise taxes has expired for tax years before 2018 (other state income and franchise tax statutes of limitations vary by state).

DERIVATIVE INSTRUMENTS

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS We use derivative instruments and other risk management techniques to reduce our exposure to adverse fluctuations in interest rates and foreign currency exchange rates in accordance with our risk management policies and for certain loan clients to allow them to hedge the risk of rising interest rates on their variable rate loans. The Company recognizes all derivatives on the consolidated balance sheet at fair value in other assets and other liabilities. On the date we enter into a derivative contract, the derivative is designated as either a fair value hedge, cash flow hedge, or a hedge designation is not made as it is a customer-related transaction. When a derivative is designated as a fair value hedge or cash flow hedge, the Company performs an assessment at inception, and, at least quarterly thereafter, to determine the effectiveness of the derivative in offsetting changes in the fair value or cash flows of the hedged items. Cash flow hedge In March 2023, the Company entered into pay-fixed, receive-variable interest-rate swap contracts classified as cash flow hedges with notional amounts aggregating $300.0 million, five year terms and varying maturity dates through 2028. These swap contracts were entered into with institutional counterparties to hedge against variability in cash flows attributable to interest rate risk related to changes in the SOFR benchmark interest rate on a portion of the Company’s variable rate deposits and borrowings. The cash flow hedges were deemed highly effective at inception. The portion of changes in the fair value of the cash flow hedges considered highly effective are recognized in other comprehensive income (loss) until the related cash flows from the hedged item are recognized in earnings. At June 30, 2023, the fair value of the cash flow hedges represent a liability of $0.5 million, of which $0.4 million (net of tax) was included in accumulated other comprehensive loss on the consolidated statements of financial condition. Other interest rate swaps and foreign exchange contracts not designated for hedge accounting During the three and six months ended June 30, 2023, changes in fair value of interest rate swaps on loans and foreign exchange contracts were gains of $10 thousand and losses of $14 thousand and were included in other income on the consolidated statements of operations. During the three and six months ended June 30, 2022, changes in fair value of interest rate swaps on loans and foreign exchange contracts were gains of $82 thousand and $0.2 million.

At June 30, 2023, unrecognized compensation expense totaled $12.8 million and will be recognized over a weighted average remaining period of 2.5 years. Restricted Stock Awards and Restricted Stock Units We have granted restricted stock awards and restricted stock units to certain employees, officers, and directors. The restricted stock awards and units are measured based on grant-date fair value, which generally reflect the closing price of our stock on the date of grant.

Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY Preferred Stock We are authorized to issue 50,000,000 shares of preferred stock with par value of $0.01 per share. Preferred shares outstanding rank senior to common shares both as to dividends and liquidation preference but generally have no voting rights. All of our shares of preferred stock had a $1,000 per share liquidation preference and there were no preferred shares outstanding since March 2022. The following table summarizes redemptions and repurchases of these depositary shares for the periods indicated: Three Months Ended Six Months Ended ($ in thousands) 2023 2022 2023 2022 Series E Preferred Stock: Depositary shares repurchased — — — 3,948,080 Preferred Stock retired (shares) — — — 98,702 Consideration paid $ — $ — $ — $ 98,703 Carrying value — — — 94,956 Impact of preferred stock redemption $ — $ — $ — $ 3,747 During the first quarter of 2022, we redeemed all of our outstanding Series E Depositary Shares, resulting in an after-tax charge of $3.7 million in the accompanying consolidated statements of operations. Common Share Repurchase Program On February 13, 2023, we announced our Board of Directors authorized the repurchase of up to $35 million of our common stock. The repurchase authorization expires in February 2024. Purchases may be made in open-market transactions, in block transactions on or off an exchange, in privately negotiated transactions or by other means as determined by our management and in accordance with the regulations of the SEC. The timing of purchases and the number of shares repurchased under the program will depend on a variety of factors including price, trading volume, corporate and regulatory requirements and market conditions. During the three and six months ended June 30, 2023, common stock repurchased under the program totaled 1,348,545 shares and 1,759,491 shares at a weighted average price of $11.85 and $12.02. As of June 30, 2023, the Company had $13.9 million remaining under the current stock repurchase authorization. Change in Accumulated Other Comprehensive (Loss) Income ("AOCI") Our AOCI includes unrealized gain (loss) on AFS securities and cash flow hedges. Changes to AOCI are presented net of the tax effect as a component of stockholders’ equity. Reclassifications from AOCI occur when a security is sold, called or matures and are recorded on the consolidated statements of operations either as a gain or loss. During the first quarter of 2022, we transferred certain AFS securities to HTM. The unrealized loss on such securities at the time of transfer continues to be reported in AOCI and is amortized over the remaining life of the security as a yield adjustment. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in AOCI and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. If a cash flow hedge is terminated or is no longer deemed highly effective, the hedge accounting is ceased and any gain or loss included in AOCI is reclassified into earnings. The following table presents changes to AOCI for the periods indicated: Three Months Ended Six Months Ended ($ in thousands) 2023 2022 2023 2022 Balance at beginning of period $ (50,489) $ (19,172) $ (40,597) $ 7,743 Unrealized loss on securities available-for-sale: Unrealized loss arising during the period (7,334) (21,016) (12,857) (59,103) Reclassification adjustment from other comprehensive income — — — (16) Total unrealized loss on securities available-for-sale (7,334) (21,016) (12,857) (59,119) Amortization of unrealized loss of available-for-sale securities transferred to held-to-maturity 252 246 505 333 Unrealized gain (loss) on cash flow hedges: Unrealized gain (loss) arising during the period 8,168 — (454) — Tax effect of current period changes (355) 5,883 3,645 16,984 Total changes, net of taxes 731 (14,887) (9,161) (41,802) Balance at end of period $ (49,758) $ (34,059) $ (49,758) $ (34,059)

VARIABLE INTEREST ENTITIES

Organization, Consolidation and Presentation of Financial Statements [Abstract]
VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES We hold ownership interests in alternative energy partnerships, qualified affordable housing partnerships and other CRA investments 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; however none of the VIE’s meet the criteria for consolidation. Unconsolidated VIEs Alternative Energy Partnerships We invested in certain alternative energy partnerships (limited liability companies) formed to provide sustainable energy projects that are designed to generate a return primarily through the realization of federal tax credits (energy tax credits). These entities were formed to invest in newly established residential and commercial solar leases and power purchase agreements. As a result of our investments, we have the right to certain investment tax credits and tax depreciation benefits (recognized on the flow through income statement method in accordance with ASC 740), and to a lesser extent, cash flows generated from the installed solar systems leased to individual consumers for a fixed period of time. While our interest in the alternative energy partnerships meets the definition of a VIE in accordance with ASC 810, we have determined that we are not the primary beneficiary because we do not have the power to direct the activities that most significantly impact the economic performance of the entities including operational and credit risk management activities. As we are not the primary beneficiary, we did not consolidate the entities. We use the HLBV method to account for our investments in alternative energy partnerships as an equity investment. Under the HLBV method, an equity method investor determines its share of an investee’s net 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 $19.1 million and $21.4 million at June 30, 2023 and December 31, 2022. The following table presents information regarding activity in our alternative energy partnerships for the periods indicated: Three Months Ended Six Months Ended ($ in thousands) 2023 2022 2023 2022 Return of capital $ 352 $ 582 $ 717 $ 1,156 Gain (loss) on investments in alternative energy partnerships 36 (1,043) (1,582) (1,201) Tax expense (benefit) recognized from HLBV application 10 (301) (457) (347) There were no fundings of alternative energy partnerships or related income tax credits recognized for the three and six months ended June 30, 2023 and 2022. 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) June 30, December 31, Cash $ 2,910 $ 4,110 Equipment, net of depreciation 233,152 237,641 Other assets 10,078 9,838 Total unconsolidated assets $ 246,140 $ 251,589 Total unconsolidated liabilities $ 11,426 $ 11,679 Maximum loss exposure $ 19,111 $ 21,410 The maximum loss exposure that would be absorbed by us in the event that all of the assets in alternative energy partnerships are deemed worthless is $19.1 million, which is our recorded investment amount at June 30, 2023. We believe that the loss exposure on our investments is reduced considering our return on our investment is provided not only by the cash flows of the underlying client leases and power purchase agreements, but also through the tax benefits, including the federal tax credit carryover that resulted from the investments. In addition, our exposure is further limited as the arrangements include a transition manager to support any transition of the solar company sponsor, whose role includes that of the servicer and operation and maintenance provider, in the event the sponsor would be required to be removed from its responsibilities (e.g., bankruptcy, breach of contract, etc.). Qualified Affordable Housing Partnerships - Low Income Housing Tax Credits We invest in limited partnerships that operate qualified affordable housing projects that qualify for LIHTC. The returns on these investments are generated primarily through allocated federal tax credits and other tax benefits. In addition, LIHTC investments contribute to our compliance with the Community Reinvestment Act. These limited partnerships are considered to be VIEs, because either (i) they do not have sufficient equity investment at risk or (ii) the limited partners with equity at risk do not have substantive kick-out rights through voting rights or substantive participating rights over the general partner. As a limited partner, we are not the primary beneficiary because the general partner has the ability to direct the activities of the VIEs that most significantly impact their economic performance. As a result, we do not consolidate these partnerships. The following table presents information regarding balances in LIHTC investments for the periods indicated: ($ in thousands) June 30, December 31, Ending balance (1) $ 42,818 $ 45,726 Aggregate funding commitment 72,997 72,967 Total amount funded 57,290 55,487 Unfunded commitment 15,707 17,480 Maximum loss exposure 42,818 45,726 (1) Included in other assets in the accompanying Consolidated Statements of Financial Condition.

Other CRA investments totaled $89.0 million and $85.0 million at June 30, 2023 and December 31, 2022. CRA investments that are accounted for under the equity method consist primarily of investments in small business investment companies (“SBICs”) and limited partnerships which provide affordable housing where our ownership percentage exceeds 3%. Under the equity method of accounting, we record our proportionate share of the profits or losses of the investment entity as an adjustment to the carrying value of the investment and as a component of noninterest income. Equity investments that do not meet the criteria to be accounted for under the equity method and do not have a readily determinable fair value are accounted for at cost under the measurement alternative to fair value with adjustments for impairment and observable price changes as applicable. These investments consist primarily of investments in limited partnerships which provide affordable housing where our partnership percentage is less than 3% and other qualifying investments such as Community Development Financial Institutions (“CDFI”) stock. 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, therefore we do not consolidate the securitization trust. Our continuing involvement in this securitization is limited to customary obligations associated with the securitization of loans, including the obligation to cure, repurchase, or substitute loans in the event of a material breach in representations. Additionally, we have the obligation to guarantee credit losses up to 12% of the aggregate unpaid principal balances at cut-off date of the securitization. This obligation is supported by a $68.8 million letter of credit between Freddie Mac and the FHLB. The maximum loss exposure that would be absorbed by us in the event that all of the assets in the securitization trust are deemed worthless is $68.8 million, which represents the aforementioned obligation to guarantee credit losses up to 12%. We believe that the loss exposure on the multifamily securitization is reduced by both loan-to-value ratios of the underlying collateral balances and the overcollateralization that exists within the securitization trust. At June 30, 2023, the remaining unpaid principal balance on the securitization totaled $91.0 million, and we have a $1.2 million repurchase reserve related to this VIE. Capital Trusts - Trust Preferred Securities In connection with our acquisition of PMB, we acquired investments in two grantor trusts. These grantor trusts were originally formed to sell and issue trust preferred securities to institutional investors (Refer to Note 7 - Long-term Debt ). We are not the primary beneficiary, and consequently, these grantor trusts are not consolidated in the consolidated financial statements. At

SUBSEQUENT EVENTS	SUBSEQUENT EVENTS We have evaluated events from the date of the consolidated financial statements on June 30, 2023 through the issuance of these consolidated financial statements included in this Quarterly Report on Form 10-Q. On July 25, 2023, the Company and PacWest announced the execution of an Agreement and Plan of Merger, pursuant to which (a) a newly formed merger subsidiary of the Company will merge with and into PacWest, with PacWest surviving (the “merger”), (b) immediately following the merger, PacWest will merge into the Company, with the Company surviving (the “second-step merger”), (c) promptly following the second-step merger, Pacific Western Bank, a California-chartered non-member bank and prior to the second-step merger, a wholly-owned subsidiary of PacWest (“PacWest Bank”), will become a member of the Federal Reserve System (the “FRS Membership”) and (d) promptly following the effectiveness of the FRS Membership, the Bank will merge into PacWest Bank, with PacWest Bank surviving as a wholly-owned subsidiary of the Company. Upon closing of the transaction, the combined holding company and bank will operate under the Banc of California name and brand. At the closing of the merger, PacWest stockholders will be entitled to receive 0.6569 of a share of the Company’s common stock for each share held of PacWest common stock. Each outstanding share of PacWest’s 7.75% series A fixed-rate reset noncumulative perpetual preferred stock will be converted into the right to receive one share of a newly created series of substantially identical preferred stock of the Company with the same terms and conditions. In connection with the proposed transaction, the Company also entered into separate investment agreements (the “Investment Agreements”) with affiliates of funds managed by Warburg Pincus LLC (the “Warburg Investors”) and certain investment vehicles sponsored, managed or advised by Centerbridge Partners, L.P. and its affiliates (the “Centerbridge Investors” and, together with the Warburg Investors, the “Investors”), which together will invest a total of $400 million for newly issued equity securities of the Company substantially concurrently with and subject to closing of the transaction. Subject to the terms and conditions of the Investment Agreements, at the closing of the transactions contemplated thereby, the Company expects to issue to the Warburg Investors and the Centerbridge Investors, in the aggregate, approximately 21.8 million shares of common stock at a purchase price of $12.30 per share and 10.8 million shares of a new class of nonvoting, common-equivalent stock at a purchase price of $12.30 per share. Additionally, the Warburg Investors will receive warrants to purchase approximately 15.9 million of the Company’s nonvoting, common-equivalent shares, and the Centerbridge Investors will receive warrants to purchase approximately 3.0 million shares of the Company’s common stock, each with an exercise price of $15.375 per share. The warrants are exercisable for a period of seven years and subject to mandatory exercise when the market price of the Company’s common stock reaches or exceeds $24.60 for twenty or more trading days during any thirty-consecutive trading day period.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2023
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, 2022 filed by us with the SEC.
Reclassification	Certain prior period amounts have been reclassified to conform to current period presentation. These reclassifications are immaterial and have no effect on net income, comprehensive income (loss), total assets or total shareholders’ equity previously reported.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 June 30, 2023 and December 31, 2022 and for the three and six months ended June 30, 2023 and June 30, 2022. 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, and Recent Accounting Guidance	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 changes in our significant accounting policies from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC, except for those described below, which reflect a new accounting policy adopted and the impact of the adoption of ASU 2022-02: Derivative Instruments - Cash Flow Hedge : The Company applies hedge accounting for certain derivative instruments used to manage interest rate risk. A cash flow hedge is a derivative instrument used to manage the variability in future expected cash flows that would otherwise be impacted by movements in interest rates. To quality for hedge accounting, the cash flow hedge must be highly effective at reducing the risk associated with the hedged exposure. The effectiveness of the hedging relationship is documented at inception and is monitored at least quarterly through the life of the transaction. A cash flow hedge that is designated as highly effective is carried at fair value with the change in fair value included in the assessment of hedge effectiveness recorded in other comprehensive income (loss) (“AOCI”) and subsequently recognized in earnings in the same period that the hedged forecasted transaction affects earnings. At that time, the amount reclassified from AOCI is presented in the same income statement line item in which the hedged transaction is reported (interest income or expense). If the cash flow hedge becomes ineffective, the change in fair value is reclassified from AOCI to earnings. Loan Modifications to Borrowers Experiencing Financial Difficulty: Prior to the adoption of ASU 2022-02, we accounted for the modification to the contractual terms of a loan that resulted in granting a concession to a borrower experiencing financial difficulties as a troubled debt restructuring (“TDR”). Effective January 1, 2023, we adopted ASU 2022-02, which eliminated TDR accounting prospectively for all restructurings occurring on or after January 1, 2023. Loans that were considered a TDR prior to the adoption of ASU 2022-02 will continue to be accounted for under the superseded TDR accounting guidance until the loan is paid off, liquidated, or subsequently modified. Since adoption of ASU 2022-02 on January 1, 2023, we have Recently Adopted Accounting Guidance: In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-02, Financial Instruments—Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures , which addresses areas identified by the FASB as part of its post-implementation review of the credit losses standard (“ASU 2016-13”) that introduced the current expected credit losses (“CECL”) model. The amendments eliminate the accounting guidance for TDRs by creditors that have adopted the CECL model and enhances the disclosure requirements for loan refinancings and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require a public business entity to disclose current-period gross write-offs for financing receivables by year of origination in the vintage disclosures. ASU 2022-02 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. We adopted ASU 2022-02 on January 1, 2023 and the impact of adoption did not have a material effect on our consolidated financial statements. Recently Issued Accounting Guidance Not Yet Adopted : In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force) (“ASU 2023-02”) , which permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method, which was previously allowed only for low-income housing tax credit (“LIHTC”) investments, if certain conditions are met. ASU 2023-02 is effective for fiscal years beginning after December 15, 2023, and including interim periods within those fiscal years. The amendment must be applied on either a modified retrospective or a retrospective basis, and early adoption is permitted. The Company is currently evaluating the impact of this update on its consolidated financial statements and related disclosures, including assessing eligibility to apply the updated guidance to our investments in alternative energy partnerships currently accounted for using the HLBV method of the equity method of accounting.
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 credit losses (“ACL”) (which includes the allowance for loan losses (“ALL”) and the reserve for unfunded noncancellable loan commitments (“RUC”)), loan repurchase reserve, realization of deferred tax assets, the fair value of assets and liabilities acquired in business combinations and related purchase price allocation, the valuation of goodwill and other intangible assets, other derivatives, 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.
Sale-leaseback Transaction	Sale-leaseback Transactions In January 2022, we completed a sale-leaseback transaction for $2.4 million and recognized a gain of $0.8 million. Gains related to sale-leaseback are included in other income in the accompanying consolidated statements of operations.
