The Bank offers a variety of financial services to meet the banking and financial needs of the communities we serve, with operations conducted through 35 banking offices, serving San Diego, Los Angeles, Santa Barbara and Orange counties, California and 72 loan production offices in California, Arizona, Oregon, Virginia, Indiana, Maryland, Colorado, Idaho, North Carolina, and Nevada as of September 30, 2015 . The Palisades Group provides financial advisory and asset management services and PTB manages and disposes of other real estate owned properties. The accounting and reporting policies of the Company are based upon U.S. generally accepted accounting principles (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 2014 Annual Report on Form 10-K. Refer to Accounting Pronouncements below for discussion of accounting pronouncements adopted in 2015 . Basis of Presentation: The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain disclosures required by 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, 2014 filed by the Company with the Securities and Exchange Commission. The December 31, 2014 balance sheet 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, 2014 filed with the Securities and Exchange Commission, but does not include all of the disclosures required by GAAP. 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 position and consolidated results of operations for the periods presented. Certain reclassifications have been made in the prior period financial statements to conform to the current period presentation. The results of operations for the three and nine months ended September 30, 2015 are not necessarily indicative of the results to be expected for the full year. 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 financial statements and disclosures provided, and actual results could differ. The allowance for loan and lease losses, reserve for loss on repurchased loans, servicing rights, realization of deferred tax assets, the valuation of goodwill and other intangible assets, mortgage banking derivatives, purchased credit impaired loan discount accretion, fair value of assets and liabilities acquired in business combinations, and the fair value measurement of financial instruments are particularly subject to change and any such change could have a material effect on the consolidated financial statements. Income Taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax basis of assets and liabilities, computed using enacted tax rates. A valuation allowance is established when necessary to reduce deferred tax assets when it is more-likely-than-not that a portion or all of the net deferred tax assets will not be realized. As of September 30, 2015 , the Company had a net deferred tax asset of $13.4 million , with no valuation allowance and as of December 31, 2014 , the Company had a net deferred tax asset of $16.4 million , with no valuation allowance (See further discussion in Note 11, Income Taxes). The effective tax rate for both the 2015 and 2014 three- and nine-month periods reflects the adoption of Accounting Standards Update (ASU) 2014-01, which relates to amortization of investments in low income housing tax credits. See the Accounting Pronouncements portion of Note 1 - Summary of Significant Accounting Policies for detail. Allowance for Loan and Lease Losses: During the year ended December 31, 2014, the Company enhanced the methodologies, processes and controls over the allowance for loan and lease losses (ALLL), due to the Company's organic and acquisitive growth and changing profile. The following is a synopsis of the enhancements for each component of ALLL: • Expand the look-back period to 28 rolling quarters to capture the full economic cycle. • Utilize net historical losses versus gross historical losses. • Expand the peer group used to determine industry average loss history to include three industry groups: i) all U.S. financial and bank holding companies, ii) all California based financial and bank holding companies, and iii) the peer group average from the Uniform Bank Performance Report. • Apply the segment specific loss emergence period to each segment's loss. • Determine qualitative reserves at each loan segment level based on a baseline risk weighting adjusted for current risks, trends and business conditions. • Disaggregate certain qualitative factors to be determined on the portfolio segment level. Accounting Pronouncements: During the nine months ended September 30, 2015 , the following pronouncements applicable to the Company became effective: In January 2014, the FASB issued guidance within ASU 2014-01, “Accounting for Investments in Qualified Affordable Housing Projects," which amends ASC 323-720 to permit entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. The Company invests in qualified affordable housing projects (affordable housing fund investments) and previously accounted for them under the equity method of accounting. The Company recognized its share of partnership losses in noninterest expense with the tax benefit recognized in the income tax provision. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments are effective for fiscal years, and interim periods within those years, beginning after December 31, 2014 and should be applied retrospectively to all periods presented. The Company elected the proportional amortization method retrospectively for all periods presented. This accounting change in the amortization methodology resulted in changes to account for amortization recognized in prior periods, which impacted the balance of tax credit investments and related tax accounts. The investment amortization expense is presented as a component of the income tax expense (benefit). The cumulative effect of the retrospective application of this accounting principle was $274 thousand at December 31, 2014 . Net income increased by $21 thousand for the three months ended September 30, 2015 and decreased by $9 thousand for the nine months ended September 30, 2015, due to the change in accounting principle. The following tables present the effect of the retrospective application of this change in accounting principle on the Company’s Consolidated Statement of Financial Condition as of December 31, 2014, and Consolidated Statements of Operations and Cash Flows for the periods indicated: BANC OF CALIFORNIA, INC.

Interim and annual disclosure is required of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. ASU 2014-04 is effective using either the modified retrospective transition method or a prospective transition method for fiscal years and interim periods within those years, beginning after December 15, 2014, and early adoption is permitted. Adoption of the new guidance did not have a significant impact on the Company’s consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing: Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.” The ASU changes the accounting for repurchase-to-maturity transactions to secured borrowing accounting. In addition, for repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The ASU also requires disclosures for certain transactions comprising (1) a transfer of a financial asset accounted for as a sale and (2) an agreement with the same transferee entered into in contemplation of the initial transfer that results in the transferor retaining substantially all of the exposure to the economic return on the transferred financial asset throughout the term of the transaction. There are additional disclosure requirements for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions that are accounted for as secured borrowings. Adoption of the new guidance did not have a significant impact on the Company’s consolidated financial statements. In August 2014, the FASB issued ASU 2014-14, “Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40), Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” Under ASU 2014-14, a mortgage loan should be derecognized and a separate receivable based on the principal and interest expected to be recovered from the governmental guarantor should be recognized upon foreclosure when all of the following conditions exist: a government guarantee exists that is not separable from the loan prior to the foreclosure; as of the date of the foreclosure the creditor has the intent to convey the real estate to the governmental agency that issued the guarantee, to make a claim on the guarantee and the creditor has the ability to recover amounts due from the governmental entity as a result of the claim; and, as of the time of the foreclosure, the claim amount that is based on the fair value of the real estate is fixed. ASU 2014-14 is effective using either the modified retrospective transition method or a prospective transition method for fiscal years and interim periods within those years, beginning after December 15, 2014. Adoption of the new guidance did not have a significant impact on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805), Simplifying the Accounting for Measurement-Period Adjustments.” This Update simplifies the accounting for adjustments made to provisional amounts recognized in a business combination, and eliminates the requirement to retrospectively account for those adjustments. The amendments to this Update require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The Updates require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in this Update require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. For public business entities, the amendments to this Update are effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. This Update should be applied prospectively to adjustments to provisional amounts that occur after the effective date of this Update with earlier application permitted for financial statements that have not been issued. The Company early adopted the amendments to this Update during the current quarterly reporting period, ended September 30, 2015. The following are recently issued accounting pronouncements also applicable to the Company: In May 2014, the FASB issued ASU No. 2014-09, “Revenue From Contracts With Customers,” which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The ASU is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606),” which deferred the effective date of this ASU by one year. Therefore, ASU 2014-09 becomes effective for the Company for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-12, “Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” The ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis," which significantly changes the consolidation analysis required under U.S. GAAP. The new consolidation guidance maintains two models: one for assessing most corporate entities based on the notion that majority voting rights indicate control (the voting model) and another for assessing entities that may be controlled through other means, such as management contracts or subordinated financial support (the variable interest model). Under the new guidance, limited partnerships will be variable interest entities, unless the limited partners have either substantive kick-out or participating rights. There is no longer a presumption that a general partner should consolidate a limited partnership. The ASU also changes the effect that fees paid to a decision maker or service provider have on the consolidation analysis. For entities other than limited partnerships, the ASU clarifies how to determine whether the equity holders (as a group) have power over the entity. The ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. Early adoption is allowed for all entities, but the guidance must be applied as of the beginning of the annual period containing the adoption date. Entities have the option of using either a full or modified retrospective approach for adoption. The Company early adopted the amendments of this update during the current quarterly reporting period. Adoption of the new guidance did not have a significant impact on the Company's consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, "Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs," which requires the debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. The amendments in this ASU are to be applied on a retrospective basis. In August 2015, the FASB issued ASU 2015-15, "Interest-Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line of Credit Arrangements," which allows guidance in ASU 2015-03 to be applied to line of credit arrangements. The Company is in the process of assessing the impact of the new guidance on its consolidated financial statements.

Business Combinations [Abstract]
BUSINESS COMBINATIONS AND ASSET SALES TRANSACTIONS	BUSINESS COMBINATIONS AND ASSET SALES TRANSACTIONS The Company completed the following acquisitions between January 1, 2014 and September 30, 2015 and used the acquisition method of accounting. Accordingly, the operating results of the acquired entities have been included in the consolidated financial statements from their respective dates of acquisition. The following table presents a summary of acquired assets and assumed liabilities along with a summary of the acquisition consideration as of the dates of acquisition: Acquisition and Date Acquired Banco Popular Branches Renovation Ready November 8, 2014 January 31, 2014 (In thousands) Assets acquired: Cash and due from banks $ 5,532 $ — Loans and leases receivable 1,065,088 — Premises, equipment, and capital leases 9,002 — Goodwill 7,653 2,239 Other intangible assets 15,777 761 Other assets 2,301 — Total assets acquired $ 1,105,353 $ 3,000 Liabilities assumed: Deposits $ 1,076,906 $ — Other liabilities 506 1,000 Total liabilities assumed 1,077,412 1,000 Total consideration paid $ 27,941 $ 2,000 Summary of consideration Cash paid $ 27,941 $ 1,000 Common stock issued — 1,000 Earn-out liabilities — 1,000 Banco Popular’s California Branch Network Acquisition Effective November 8, 2014, the Bank acquired 20 full-service branches from Banco Popular North America (BPNA) in the Southern California banking market (the BPNA Branch Acquisition). The purchase price, net of deposit premiums received of $3.9 million , was $24.0 million . At the time of its completion, the transaction added $1.07 billion in loans and $1.08 billion in deposits to the Bank. The following table summarizes the total consideration transferred as part of the BPNA Branch Acquisition as well as the fair value adjustments to the net assets acquired as of the acquisition date: November 8, 2014 (In thousands) Total Consideration $ 27,941 Net assets pre-acquisition 24,027 Fair value adjustments Loans receivable $ (19,526 ) Core deposit intangibles 15,777 Certificates of deposit purchase premium (1,208 ) Premises and equipment 1,218 Total fair value adjustments (3,739 ) Fair value of net assets acquired 20,288 Consideration paid in excess of fair value of net assets acquired (goodwill) $ 7,653 The Company recorded core deposit intangible assets of $15.8 million as part of the BPNA Branch Acquisition. Core deposit intangible assets were valued using a net cost savings method and was calculated as the present value of the estimated net cost savings attributable to the core deposit base over the expected remaining life of the deposits. The cost savings derived from the core deposit balance were calculated as the difference between the prevailing alternative cost of funds and the estimated cost of the core deposits. The core deposit intangible is being amortized over its estimated useful life of 10 years using the sum of years-digits amortization methodology. The fair value of loans acquired from BPNA was estimated by utilizing a methodology wherein similar loans were aggregated into pools. Cash flows for each pool were determined by estimating future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value based on a market rate for similar loans. There was no carryover of BPNA's allowance for loan losses associated with the acquired loans as the loans were initially recorded at fair value. The fair value of savings and transaction deposit accounts acquired from BPNA was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. Certificates of deposit were valued by projecting the expected cash flows based on the remaining contractual terms of the certificates of deposit. These cash flows were discounted based on market rates for certificates of deposit with corresponding remaining maturities. Direct costs related to the BPNA Branch Acquisition were expensed as incurred and amounted to $4.3 million for the year ended December 31, 2014. During the three months ended September 30, 2015, the Company finalized its purchase accounting for the BPNA Branch Acquisition and recorded the measurement period adjustments. The measurement period adjustments included recording Goodwill of $7.7 million , an additional discount of $7.4 million to Loans and Leases Receivable, and an additional premium of $292 thousand to Deposits. Recorded in the Consolidated Statements of Operations, the cumulative life to date measurement period adjustments related to the loan discount and deposit premium amortization were a $33 thousand decrease in Interest and Dividend Income on Loans and a $110 thousand decrease in Interest Expense on Deposits, respectively. RenovationReady® Acquisition Effective January 31, 2014, the Company acquired certain assets, including service contracts and intellectual property, of RenovationReady, a provider of specialized loan services to financial institutions and mortgage bankers that originate agency eligible residential renovation and construction loan products. The RenovationReady acquisition was accounted for under GAAP guidance for business combinations. The purchased identifiable intangible assets and assumed liabilities were recorded at their estimated fair values as of January 31, 2014. The Company recorded $2.2 million of goodwill and $761 thousand of other intangible assets. The other intangible assets are related to a customer relationship intangible. Pro Forma Information While the BPNA Branch Acquisition is considered a purchase of a business for accounting purposes, pro forma income statement information is not presented because the BPNA Branch Acquisition does not represent the acquisition of a business which has continuity both before and after the acquisition. Pro formation income statement information for RenovationReady is not presented because it is immaterial. Building Sale During the nine months ended September 30, 2015, the Company sold a certain improved real property office complex located at 1588 South Coast Drive, Costa Mesa, California (the Property) at a sale price of approximately $52.3 million with a gain on sale of $9.9 million . The Property had a book value of $42.3 million at the sale date. Additionally, the Company incurred selling costs of $2.3 million for this transaction, which were reported in Professional Fees and All Other Expenses in the Consolidated Statements of Operations. Branch Sale On September 25, 2015, the Bank completed a branch sale transaction to Americas United Bank, a California banking corporation (AUB). In the transaction, the Bank sold two branches and certain related assets and deposit liabilities to AUB as well as certain loans. The transaction included a transfer of $46.9 million of deposits to AUB. Additionally, as part of the transaction, the leases related to both locations were assumed by AUB. The Company recognized a gain of $163 thousand from this transaction, which is included in Other Income in the Consolidated Statements of Operations. The Bank also sold certain loans of $40.2 million to AUB as part of the transaction. The Company recognized a gain of $644 thousand from the sale of these loans, which is included in Net Gain on Sale of Loans in the Consolidated Statements of Operations.

FAIR VALUES OF FINANCIAL INSTRU

FAIR VALUES OF FINANCIAL INSTRUMENTS	9 Months Ended
	Sep. 30, 2015
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 employs an independent pricing service that utilizes matrix pricing 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 SBA loan pool securities, U.S. GSE and agency securities, private label residential MBS, and agency residential MBS, non-agency commercial MBS, and non-agency corporate bonds. When a market is illiquid or there is a lack of transparency around the inputs to valuation, 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, 2015 or December 31, 2014 . 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 markets are currently offering for portfolios with similar characteristics. Therefore, loans held for sale subjected to recurring fair value adjustments are classified as Level 2. The fair value includes the servicing value of the loans as well as any accrued interest. Derivative Assets and Liabilities : The Company’s derivative assets and liabilities are carried at fair value as required by GAAP and are accounted for as freestanding derivatives. The Company has 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 the LIBOR benchmark interest rate on the Company’s ongoing LIBOR-based variable rate deposits and other borrowings. For hedged derivatives, the Company records changes in fair value in Accumulated Other Comprehensive Income (AOCI) in the Consolidated Statements of Financial Condition. For non-hedged derivatives, the Company records changes in fair value in Other Income in the Consolidated Statements of Operations. The Company also enters into interest rate lock commitments (IRLCs) with prospective residential mortgage borrowers. These commitments are carried at fair value based on the fair value of the underlying mortgage loans which are based on observable market data. The Company adjusts the outstanding IRLCs with prospective borrowers based on an expectation that it will be exercised and the loan will be funded. Changes in fair value are recorded in Net Revenue on Mortgage Banking Activities in the Consolidated Statements of Operations. These commitments are classified as Level 2 in the fair value disclosures, as the valuations are based on market observable inputs. Additional derivative assets and liabilities, typically mortgage-backed to-be-announced (TBA) securities, are used to hedge fair value changes, driven by changes in interest rates, in the Company’s mortgage assets. The Company hedges the period from the interest rate lock (assuming a fall-out factor for loans that ultimately do not close) to the date of the loan sale. The estimated fair value is based on current market prices for similar instruments. Given the meaningful level of secondary market activity for derivative contracts, active pricing is available for similar assets and accordingly, the Company classifies its derivative assets and liabilities as Level 2. Mortgage Servicing Rights: The Company retains servicing on some of its mortgage loans sold and elected the fair value option for valuation of these mortgage servicing rights (MSRs). The value is based on a third party provider that calculates the present value of the expected net servicing income from the portfolio based on key factors that include interest rates, prepayment assumptions, discount rate and estimated cash flows. Because of the significance of unobservable inputs, these servicing rights are classified as Level 3. At December 31, 2014, $5.9 million of the mortgage servicing rights were valued based on a market bid that settled subsequent to that date, which was included as Level 3.

The following table presents quantitative information about Level 3 fair value measurements on a recurring basis, other than the mortgage servicing rights were valued based on a market bid that settled subsequent to that date, which was included as Level 3 at December 31, 2014, as of the dates indicated: Fair Value (In thousands) Valuation Technique(s) Unobservable Input(s) Range (Weighted Average) September 30, 2015 Mortgage servicing rights $ 40,837 Discounted cash flow Discount rate 9.00% to 18.00% (9.88%) Prepayment rate 6.07% to 34.69% (12.09%) December 31, 2014 Mortgage servicing rights $ 13,135 Discounted cash flow Discount rate 9.00% to 19.50% (10.09%) Prepayment rate 4.59% to 31.02% (13.22%) September 30, 2014 Mortgage servicing rights $ 11,376 Discounted cash flow Discount rate 10.00% to 21.22% (10.70%) Prepayment rate 4.71% to 34.76% (12.41%) The significant unobservable inputs used in the fair value measurement of the Company’s servicing rights include the discount rate and prepayment rate. 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. Assets and Liabilities Measured on a Non-Recurring Basis Securities Held to Maturity: Investment securities that the Company has the ability and the intent to hold to maturity are classified as held to maturity. Investment securities classified as held to maturity are carried at cost. The fair values of securities held to maturity are generally determined by quoted market prices in active markets, if available (Level 1). If quoted market prices are not available, the Company employs an independent pricing service that utilizes matrix pricing 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). 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. When a market is illiquid or there is a lack of transparency around the inputs to valuation, the securities are classified as Level 3 and reliance is placed upon internally developed models, and management judgment and evaluation for valuation. Only securities held to maturity with other-than-temporary impairment (OTTI) are considered to be carried at fair value. The Company did not have any OTTI on securities held to maturity at September 30, 2015 . Impaired Loans and Leases: The fair value of impaired loans and leases with specific allocations of the allowance for loan and lease losses based on collateral values is generally based on recent real estate appraisals. 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 significant and result in a Level 3 classification of the inputs for determining fair value. Loans Held for Sale, Carried at Lower of Cost or Fair Value: The Company records non-conforming jumbo mortgage loans held for sale at the lower of cost or fair value, on an aggregate basis. The Company obtains fair values from a third party independent valuation service provider. Loans held for sale accounted for at the lower of cost or fair value are considered to be recognized at fair value when they are recorded at below cost, on an aggregate basis, and are classified as Level 2. SBA Servicing Assets: SBA servicing assets represent the value associated with servicing SBA loans that have been sold. The fair value for SBA servicing assets is determined through discounted cash flow analysis and utilizes discount rates and prepayment speed assumptions as inputs. All of these assumptions require a significant degree of management estimation and judgment. The fair market valuation is performed on a quarterly basis for SBA servicing assets. SBA servicing assets are accounted for at the lower of cost or market value and considered to be recognized at fair value when they are recorded at below cost and are classified as Level 3. Other Real Estate Owned Assets: Other real estate owned assets (OREO) are recorded at the fair value less estimated costs to sell at the time of foreclosure. The fair value of other real estate owned assets is generally based on recent real estate appraisals adjusted for estimated selling costs. These appraisals may utilize a single valuation approach or a combination of approaches 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 may be significant and result in a Level 3 classification of the inputs for determining fair value. Only OREO with a valuation allowance are considered to be carried at fair value. The Company recorded valuation allowance expense for OREO of $16 thousand and $0 for the three months ended September 30, 2015 and 2014 , respectively, and $38 thousand and $0 for the nine months ended September 30, 2015 and 2014 , respectively. Alternative Investments (Affordable Housing Fund Investment, SBIC, and Other Investment): The Company generally accounts for its percentage ownership of alternative investment funds at cost, subject to impairment testing. These are non-public investments that cannot be redeemed since the Company’s investment is distributed as the underlying investments are liquidated, which generally takes 10 years . There are currently no plans to sell any of these investments prior to their liquidation. The alternative investments carried at cost are considered to be measured at fair value on a non-recurring basis when there is impairment. The Company had unfunded commitments of $487 thousand , $5.6 million , and $2.0 million for Affordable House Fund Investment, SBIC, and Other Investments at September 30, 2015 , respectively.

FHLB and Other Bank Stock: FHLB and other bank stock is recorded at cost. Ownership of FHLB stock is restricted to member banks, and purchases and sales of these securities are at par value with the issuer (Level 2). Securities Held to Maturity: The fair values of securities held to maturity are based on pricing received from an independent pricing service that utilizes matrix pricing to calculate fair value (Level 2). Loans and Leases Receivable, Net of Allowance for Loan and Lease Losses: The fair value of loans and leases receivable is estimated based on the discounted cash flow approach. The discount rate was derived from the associated yield curve plus spreads and reflects the rates offered by the Bank for loans with similar financial characteristics. Yield curves are constructed by product and payment types. These rates could be different from what other financial institutions could offer for these loans. No adjustments have been made for changes in credit within the loan portfolio. Additionally, the fair value of our loans may differ significantly from the values that would have been used had a ready market existed for such loans and may differ materially from the values that we may ultimately realize (Level 3). Accrued Interest Receivable: The carrying amount of accrued interest receivable approximates its fair value (Level 1). Deposits: The fair value of deposits is estimated based on discounted cash flows. The cash flows for non-maturity deposits, including savings accounts and money market checking, are estimated based on their historical decaying experiences. The discount rate used for fair valuation is based on interest rates currently being offered by the Bank on comparable deposits as to amount and term (Level 3). Advances from Federal Home Loan Bank: The fair values of advances from FHLB are estimated based on the discounted cash flows approach. The discount rate was derived from the current market rates for borrowings with similar remaining maturities (Level 2). Long Term Debt: Fair value of long term debt is determined by observable data such as market spreads, cash flows, yield curves, credit information, and respective terms and conditions for debt instruments (Level 2). Accrued Interest Payable: The carrying amount of accrued interest payable approximates its fair value (Level 1).

In the case of mortgage-backed securities, collateralized loan obligations, and SBA loan pool securities, expected maturities may differ from contractual maturities because borrowers generally have the right to call or prepay obligations with or without call or prepayment penalties. For that reason, mortgage-backed securities, collateralized loan obligations, and SBA loan pool securities are not included in the maturity categories.

The unrealized losses were largely attributable to wider pricing spreads for corporate bonds at September 30, 2015. The Company monitors to ensure it has adequate credit support, and as of September 30, 2015 , the Company did not have the intent to sell these securities and it is not likely that it will be required to sell the securities before their anticipated recoveries.

As of September 30, 2015 and December 31, 2014 , the NTM loans totaled $759.3 million , or 16.1 percent of the total gross loan portfolio, and $350.6 million , or 8.9 percent of the total gross loan portfolio, respectively. The total NTM portfolio increased by $408.7 million , or 116.6 percent , during the nine months ended September 30, 2015 , due mainly to interest only loans transferred from loans held for sale of $277.5 million .

The loans are generally interest only with a 15 year-balloon payment due at maturity. At September 30, 2015 and December 31, 2014 , Green Loans totaled $116.8 million and $128.2 million , respectively. At September 30, 2015 and December 31, 2014 , $10.2 million and $12.5 million , respectively, of the Company’s Green Loans were non-performing. As a result of their unique payment feature, Green Loans possess higher credit risk due to the potential for negative amortization; however, management believes the risk is mitigated through the Company’s loan terms and underwriting standards, including its policies on loan-to-value ratios and the Company’s contractual ability to curtail loans when the value of the underlying collateral declines. The Company discontinued origination of the Green Loan products 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. As of September 30, 2015 and December 31, 2014 , interest only loans totaled $630.5 million and $209.3 million , respectively. As of September 30, 2015 and December 31, 2014 , $3.7 million and $2.0 million of the interest only loans were non-performing, respectively. Loans with the Potential for Negative Amortization Negative amortization loans totaled $12.0 million and $13.1 million at September 30, 2015 and December 31, 2014 , respectively. The Company discontinued origination of negative amortization loans in 2007. At September 30, 2015 and December 31, 2014 , none of the loans that had 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 risk is mitigated through the loan terms and underwriting standards, including the Company’s policies on loan-to-value ratios. While Green Loans have the potential for negative amortization, they are excluded from the loans with the potential for negative amortization discussed in this paragraph. Risk Management of Non-Traditional Mortgages The Company has determined that significant performance indicators for NTMs are loan-to-value (LTV) and Fair Isaac Corporation (FICO) scores. Accordingly, the Company manages credit risk in the NTM portfolio through semi-annual review of the loan portfolio that includes refreshing FICO scores on the Green Loans and home equity lines of credit, as needed in conjunction with portfolio management, and ordering third party automated valuation models. The loan review is designed to provide a method of identifying borrowers who may be experiencing financial difficulty before they actually fail to make a loan payment. Upon receipt of the updated FICO scores, an exception report is run to identify loans with a decrease in FICO of 10 percent or more and/or a resulting FICO of 620 or less. The loans are then further analyzed to determine if the risk rating should be downgraded which will increase the reserves the Company will establish for potential losses. A report of the semi-annual loan review is published and regularly monitored. As these loans are revolving lines of credit, the Company, based on the loan agreement and loan covenants of the particular loan, as well as applicable rules and regulations, could suspend the borrowing privileges or reduce the credit limit at any time the Company reasonably believes that the borrower will be unable to fulfill their repayment obligations under the agreement or certain other conditions are met. In many cases, the decrease in FICO is the first indication that the borrower may have difficulty in making their future payment obligations. The Company proactively manages the NTM portfolio by performing detailed analyses on the portfolio. The Company’s Internal Asset Review Committee (IARC) conducts meetings on at least a quarterly basis to review the loans classified as special mention, substandard, or doubtful and determines whether a suspension or reduction in credit limit is warranted. If a line has been suspended and the borrower would like to have their credit privileges reinstated, they would need to provide updated financials showing their ability to meet their payment obligations. On the interest only loans, the Company projects future payment changes to determine if there will be a material increase in the required payment and then monitors the loans for possible delinquency. The individual loans are monitored for possible downgrading of risk rating. NTM Performance Indicators The following table presents the Company’s NTM Green Loans first lien portfolio at September 30, 2015 by FICO scores that were obtained during the quarter ended June 30, 2015, comparing to the FICO scores for those same loans that were obtained during the quarter ended December 31, 2014: September 30, 2015 By FICO Scores Obtained During the Quarter Ended June 30, 2015 By FICO Scores Obtained During the Quarter Ended December 31, 2014 Change Count Amount Percent Count Amount Percent Count Amount Percent ($ in thousands) FICO Score 800+ 23 $ 15,178 13.5 % 28 $ 19,338 17.3 % (5 ) $ (4,160 ) (3.8 )% 700-799 69 54,896 49.0 % 65 47,770 42.5 % 4 7,126 6.5 % 600-699 25 18,198 16.2 % 26 27,575 24.6 % (1 ) (9,377 ) (8.4 )% <600 7 7,815 7.0 % 8 11,836 10.6 % (1 ) (4,021 ) (3.6 )% No FICO 11 15,987 14.3 % 8 5,555 5.0 % 3 10,432 9.3 % Totals 135 $ 112,074 100.0 % 135 $ 112,074 100.0 % — $ — — % The Company updates FICO scores on a semi-annual basis, typically in the second and fourth quarters or as needed in conjunction with proactive portfolio management.

Allowance for Loan and Lease Losses The Company has an established credit risk management process that includes regular management review of the loan and lease portfolio to identify problem loans and leases. During the ordinary course of business, management becomes aware of borrowers and lessees that may not be able to meet the contractual requirements of the loan and lease agreements. Such loans and leases are subject to increased monitoring. Consideration is given to placing the loan or lease on non-accrual status, assessing the need for additional allowance for loan and lease losses, and partial or full charge-off. The Company maintains the allowance for loan and lease losses at a level that is considered adequate to cover the estimated and known inherent risks in the loan and lease portfolio. The Company also maintains a reserve for unfunded loan commitments at a level that is considered adequate to cover the estimated and known inherent risks. The probability of usage of the unfunded loan commitments and credit risk factors determined based on outstanding loan balance of the same customer or outstanding loans that share similar credit risk exposure are used to determine the adequacy of the reserve. As of September 30, 2015 and December 31, 2014 , the reserve for unfunded loan commitments was $1.7 million and $1.9 million , respectively. The credit risk monitoring system is designed to identify impaired and potential problem loans, and to permit 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 which it believes should be effective in ensuring that the Company maintains an adequate allowance for credit losses. The Board of Directors provides oversight and guidance for management’s allowance evaluation process, including quarterly valuations, and consideration of management’s determination of whether the allowance is adequate to absorb losses in the loan and lease portfolio. The determination of the amount of the allowance for loan and lease losses and the provision for loan and lease losses is based on management’s current judgment about the credit quality of the loan and lease portfolio and takes into consideration known relevant internal and external factors that affect collectability when determining the appropriate level for the allowance for loan and lease losses. Additions to the allowance for loan and lease losses are made by charges to the provision for loan and lease losses. Identified credit exposures that are determined to be uncollectible are charged against the allowance for loan and lease losses. Recoveries of previously charged off amounts, if any, are credited to the allowance for loan and lease losses.

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 a 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. For the nine months ended September 30, 2015 , there were 15 modifications through bankruptcy discharges. There was one modification through bankruptcy discharge for the three and nine months ended September 30, 2014 .

Credit Quality Indicators The Company categorizes loans and leases into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. 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 and leases individually by classifying the loans and leases as to credit risk. This analysis includes all loans and leases delinquent over 60 days and non-homogeneous loans and leases such as commercial and commercial real estate loans and leases. Classification of problem single family residential loans is performed on a monthly basis while analysis of non-homogeneous loans and leases is performed on a quarterly basis. The Company uses the following definitions for risk ratings: Pass : Loans and leases 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/Loss”. Special Mention : Loans and leases 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 and leases 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 and leases so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful/Loss : Loans and leases 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. Not-Rated : When accrual of income on a pool of purchased credit impaired (PCI) loans with common risk characteristics is appropriate in accordance with ASC 310-30, individual loans in those pools are not risk-rated. The credit criteria evaluated are FICO scores, loan-to-value, delinquency, and actual cash flows versus expected cash flows of the loan pools. Loans and leases not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans and leases.

Transfers and Servicing [Abstract]
SERVICING RIGHTS	SERVICING RIGHTS The Company retains mortgage servicing rights (MSRs) from certain of its sales of residential mortgage loans. MSRs on residential mortgage loans are reported at fair value. Income earned by the Company on its MSRs is derived primarily from contractually specified mortgage servicing fees and late fees, net of curtailment costs and third party subservicing costs. The Company retains servicing rights in connection with its SBA loan operations, which are measured using the amortization method. Income (loss) from servicing rights was $(2.3) million and $924 thousand for the three months ended September 30, 2015 and 2014 , respectively, and $(689) thousand and $3.0 million for the nine months ended September 30, 2015 and 2014 , respectively. The Company recognized losses on the fair values of servicing rights of $5.5 million and $412 thousand for the three months ended September 30, 2015 and 2014, respectively, and $8.6 million and $1.2 million for the nine months ended September 30, 2015 and 2014, respectively. The decreases were partially offset by $1.9 million and $3.8 million increases, respectively, in servicing fees for the three and nine months ended September 30, 2015, comparing to the respective prior year periods. The decrease in fair value of servicing rights was due to generally lower interest rates and the increase in servicing fees was due to the increase in unpaid principal balance of loans sold with servicing retained. These amounts are reported in Loan Servicing Income (Loss) in the Consolidated Statements of Operations. The following table presents a composition of servicing rights as of the dates indicated: September 30, 2015 December 31, 2014 (In thousands) Mortgage servicing rights, at fair value $ 40,837 $ 19,082 SBA servicing rights, at cost 809 484 Total $ 41,646 $ 19,566 Mortgage loans sold with servicing retained are not reported as assets and are subserviced by a third party vendor. The unpaid principal balance of these loans at September 30, 2015 and December 31, 2014 was $4.06 billion and $1.92 billion , respectively. Custodial escrow balances maintained in connection with serviced loans were $32.5 million and $8.3 million at September 30, 2015 and December 31, 2014 , respectively.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES For the three months ended September 30, 2015 and 2014 , income tax expense was $9.3 million and $903 thousand , respectively, and the effective tax rate was 38.9 percent and 7.4 percent , respectively. For the nine months ended September 30, 2015 and 2014 , income tax expense was $30.3 million and $1.5 million , respectively, and the effective tax rate was 41.3 percent and 7.1 percent , respectively. The Company’s effective tax rate increased due to the release of valuation allowance during the three and nine months ended September 30, 2014. 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 existence of any cumulative losses in the current year and the prior two years, the amount of taxes paid in available carry-back years, future taxable income and tax planning strategies. Based on this analysis, management determined that it was more likely than not that all of the deferred tax assets would be realized. Therefore, no valuation allowance was provided against the deferred tax assets of $13.4 million and $16.4 million at September 30, 2015 and December 31, 2014 , respectively. ASC 740-10-25 (formerly FIN 48) 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 $0 and $5.4 million at September 30, 2015 and December 31, 2014 , respectively. The Company has changed its tax accounting method for various items and filed amended state income tax returns to reflect audit adjustments. As a result, the total amount of unrecognized tax benefits has decreased by $5.4 million . The Company does not believe that the unrecognized tax benefits will change within the next twelve months. As of September 30, 2015 , the total unrecognized tax benefit that, if recognized, would impact the effective tax rate was $0 . At September 30, 2015 and December 31, 2014 , the Company had $0 and $23 thousand accrued for interest or penalties, respectively. 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 examination by U.S. Federal taxing authorities for years before 2010 (with the exception of Gateway Bancorp, a predecessor entity, which is currently under exam by the Internal Revenue Service for the 2008 and 2009 tax years).The statute of limitations for the assessment of California Franchise taxes has expired for tax years before 2010 (other state income and franchise tax statutes of limitations vary by state). ASU 2014-01 was adopted effective January 1, 2015. Under this standard, amortization of investments in Qualified Affordable Housing Projects is reported within income tax expense.

Mortgage Banking Activities [Abstract]
MORTGAGE BANKING ACTIVITIES	MORTGAGE BANKING ACTIVITIES The Bank originates conforming single family residential mortgage loans and sells these loans in the secondary market. The amount of net revenue on mortgage banking activities is a function of mortgage loans originated for sale and the fair values of these loans and related derivatives. Net revenue on mortgage banking activities includes mark to market pricing adjustments on loan commitments and forward sales contracts, and initial capitalized value of mortgage servicing rights (MSRs). During the three and nine months ended September 30, 2015 , the Bank originated $1.13 billion and $3.40 billion , respectively, and sold $1.19 billion and $3.33 billion , respectively, of conforming single family residential mortgage loans in the secondary market. The net gain and margin were $32.9 million and 2.92 percent , respectively, and loan origination fees were $4.1 million for the three months ended September 30, 2015 . For the nine months ended September 30, 2015 , the net gain and margin were $102.1 million and 3.00 percent , respectively, and loan origination fees were $12.2 million . Included in the net gain is the initial capitalized value of our MSRs, which totaled $11.6 million and $35.1 million , on loans sold to Fannie Mae, Freddie Mac and Ginnie Mae for the three and nine months ended September 30, 2015 , respectively. During the three and nine months ended September 30, 2014 , the Bank originated $801.5 million and $2.03 billion , respectively, and sold $798.3 million and $1.98 billion , respectively, of conforming single family residential mortgage loans in the secondary market. The net gain and margin were $23.8 million and 2.97 percent , respectively, and loan origination fees were $3.1 million for the three months ended September 30, 2014 . For the nine months ended September 30, 2014 , the net gain and margin were $62.2 million and 3.07 percent , respectively, and loan origination fees were $8.2 million . Included in the net gain is the initial capitalized value of our MSRs, which totaled $7.3 million and $17.9 million , on loans sold to Fannie Mae and Freddie Mac for the three and nine months ended September 30, 2014 , respectively. Mortgage Loan Repurchase Obligations In addition to net revenue on mortgage banking activities, the Company records provisions to the representation and warranty reserve representing our initial estimate of losses on probable mortgage repurchases or loss reimbursements. Total provision for loan repurchases was $716 thousand and $1.6 million for the three months ended September 30, 2015 and 2014 , respectively, and $3.6 million and $3.1 million for the nine months ended September 30, 2015 and 2014 , respectively. Of these total provisions for loan repurchases, the Company recorded an initial provision for loan repurchases of $537 thousand and $402 thousand for the three months ended September 30, 2015 and 2014 , respectively, and $1.6 million and $1.0 million for the nine months ended September 30, 2015 and 2014 , respectively, against net revenue on mortgage banking activities. The following table presents a summary of activity in the reserve for losses on repurchased loans for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 (In thousands) Balance at beginning of period $ 9,411 $ 6,174 $ 8,303 $ 5,427 Provision for loan repurchases 716 1,556 3,617 3,094 Payments made for loss reimbursement on sold loans (1,029 ) (685 ) (2,822 ) (1,476 ) Balance at end of period $ 9,098 $ 7,045 $ 9,098 $ 7,045 In addition to the reserve for losses on repurchased loans at September 30, 2015, the Company may receive repurchase demands in future periods that could be material to the Company's financial position or results of operations. No such demands were received during the three or nine months ended September 30, 2015 that had not already been reserved for at September 30, 2015.

RISK MANAGEMENT AND DERIVATIVE

RISK MANAGEMENT AND DERIVATIVE INSTRUMENTS	9 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
RISK MANAGEMENT AND DERIVATIVE INSTRUMENTS	RISK MANAGEMENT AND 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. The Company utilizes forward contracts and investor commitments to economically hedge mortgage banking products and may from time to time use interest rate swaps as hedges against certain liabilities. On September 30, 2013 and January 30, 2015, the Company entered into pay-fixed, receive-variable interest-rate swap contracts for the notional amounts of $50.0 million and $25.0 million , respectively, with maturity dates of September 27, 2018 and January 30, 2022 , respectively. These swap contracts were entered into with institutional counterparties to hedge against variability in cash flows attributable to interest rate risk caused by changes in the LIBOR benchmark interest rate on the Company’s ongoing LIBOR based variable rate deposits and borrowings. During the quarter ended September 30, 2015, the Company exited the underlying hedged items related to interest rate swaps designated as cash flow hedges. As a result, the Company discontinued hedge accounting related to these interest rate swaps, and reclassified the fair value of the derivatives from AOCI into earnings. For hedged derivatives, the Company records changes in fair value in AOCI in the Consolidated Statements of Financial Condition. For non-hedged derivatives, the Company’s income statement classification policy is to record hedge ineffectiveness and the component of derivatives excluded from the assessment of hedge effectiveness in Other Income in the Consolidated Statements of Operations. As of September 30, 2015, the fair value of these derivative instruments discontinued from hedge accounting was $918 thousand , which was reclassified into earnings. The Company originates residential real estate mortgage loans and generates revenues from the origination and sale of these loans. Although management closely monitors market conditions, such activities are sensitive to fluctuations in prevailing interest rates and real estate markets. As of September 30, 2015 , approximately 76.3 percent of all properties securing loans held for sale were located in California. A change in the underlying economic conditions of the California residential real estate market could have an adverse impact on the Company’s results of operations. In connection with mortgage banking activities, if interest rates increase, the value of the Company’s loan commitments to borrowers and fixed rate mortgage loans held-for-sale are adversely impacted. The Company attempts to economically hedge the risk of the overall change in the fair value of loan commitments to borrowers and mortgage loans held for sale by selling forward contracts on securities with government-sponsored enterprises (GSEs) and investors in loans. Forward contracts on securities of GSEs and loan commitments to borrowers are non-designated derivative instruments and the gains and losses resulting from these derivative instruments are included in Net Revenue on Mortgage Banking Activities in the Consolidated Statements of Operations. At September 30, 2015 , the resulting derivative assets of $9.7 million and liabilities of $4.9 million , are included in Other Assets and Accrued Expenses and Other Liabilities, respectively, on the Consolidated Statements of Financial Condition. At September 30, 2015 , the Company had outstanding forward sales commitments totaling $517.0 million . At September 30, 2015 , the Company was committed to fund loans for borrowers of approximately $309.2 million . The net losses relating to free-standing derivative instruments used for risk management were $2.7 million and $2.5 million for the three months ended September 30, 2015 and 2014 , respectively, and $5.4 million and $11.6 million for the nine months ended September 30, 2015 and 2014 , respectively, and are included in Net Revenue on Mortgage Banking Activities in the Consolidated Statements of Operations. The following table presents the amount and market value of derivative instruments included in the Consolidated Statements of Financial Condition as of the dates indicated. Note 3 contains further disclosures pertaining to the fair value of mortgage banking derivatives.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK COMPENSATION PLANS	STOCK COMPENSATION PLANS Share-based Compensation Expense For the three months ended September 30, 2015 and 2014 , share-based compensation expense was $2.4 million and $1.7 million , respectively, and the related tax benefits were $991 thousand and $711 thousand , respectively. For the nine months ended September 30, 2015 and 2014 , share-based compensation expense was $6.6 million and $4.6 million , respectively, and the related tax benefits were $2.8 million and $1.9 million , respectively. On July 16, 2013, the Company’s stockholders approved the Company’s 2013 Omnibus Stock Incentive Plan (the 2013 Omnibus Plan). Upon the approval of the 2013 Omnibus Plan, the Company ceased being able to grant new awards under the Company’s 2011 Omnibus Incentive Plan or any prior equity incentive plans. The 2013 Omnibus Plan provides that the aggregate number of shares of Company common stock that may be subject to awards under the 2013 Omnibus Plan will be 20 percent of the then outstanding shares of Company common stock (the Share Limit), provided that in no event will the Share Limit be less than the greater of 2,384,711 shares of Company common stock and the aggregate number of shares of Company common stock with respect to which awards have been properly granted under the 2013 Omnibus Plan up to that point in time. As of September 30, 2015 , based on the number of shares then registered for issuance under the 2013 Omnibus Plan, 2,428,806 shares were available for future awards under the 2013 Omnibus Plan. Unrecognized Share-based Compensation Expense The following table presents unrecognized share-based compensation expense as of September 30, 2015 : Unrecognized Expense Average Expected Recognition Period ($ in thousands) Stock option awards $ 890 2.8 years Restricted stock awards and restricted stock units 11,521 2.7 years Total $ 12,411 2.7 years Stock Options The Company has issued stock options to certain employees, officers and directors.

The restricted stock awards and units are valued at the closing price of the Company’s stock on the date of award. The restricted stock awards and units fully vest after a specified number of years (ranging from one to five years ) of continued employment from the date of grant. The Company recognizes an income tax deduction in an amount equal to the taxable income reported by the holders of the restricted stock, generally when vested or, in the case of restricted stock units, when settled. The following table represents unvested restricted stock awards and restricted stock units activity as of and for the three and nine months ended September 30, 2015 : Three Months Ended September 30, 2015 Nine Months Ended September 30, 2015 Number of Shares Weighted- Average Price per Share Number of Weighted- Outstanding at beginning of period 1,592,930 $ 12.38 1,287,302 $ 12.53 Granted 87,877 $ 13.75 754,858 $ 12.33 Vested (78,026 ) $ 13.14 (364,255 ) $ 12.65 Forfeited (95,880 ) $ 12.06 (171,004 ) $ 12.16 Outstanding at end of period 1,506,901 $ 12.44 1,506,901 $ 12.44 Stock Appreciation Rights On August 21, 2012, the Company granted to its chief executive officer a ten -year stock appreciation right (SAR) with respect to 500,000 shares (Initial SAR) of the Company’s common stock with a base price of $12.12 per share. One-third of the Initial SAR vested on the grant date, one-third vested on the first anniversary of the grant date and one-third vested on the second anniversary of the grant date such that the SAR was fully vested on the second anniversary of the grant date. Upon cessation of the chief executive officer’s service with the Company for “Cause” or without “Good Reason” (including a cessation of service following the expiration of the term of the chief executive officer’s employment agreement), the vested portion of all SARs will expire 90 days following the cessation of service. Except as otherwise described below for Additional SAR VI, additional SARs (Additional SARs) have been issued to the Company’s chief executive officer with the same terms and conditions (including vesting and dividend equivalent rights) as the Initial SAR pursuant to the anti-dilution provisions under the SAR agreement with the Company due to the Company’s subsequent issuances of shares of common stock. On May 21, 2014, the Company issued additional SARs (Additional SAR VI) to the Company’s chief executive officer relating to a public offering of the Company’s tangible equity units (TEUs). Each TEU is comprised of a prepaid stock purchase contract (each, a Purchase Contract) and a junior subordinated amortizing note due May 15, 2017 issued by the Company (each, an Amortizing Note). Unless settled early at the holder’s option, each Purchase Contract will automatically settle and the Company will deliver a number of shares of its voting common stock based on the then applicable market value of the voting common stock, ranging from an initial minimum settlement rate of 4.4456 shares per Purchase Contract (subject to adjustment) if the applicable market value is equal to or greater than $11.247 per share to an initial maximum settlement rate of 5.1124 shares per Purchase Contract (subject to adjustment) if the applicable market value is less than or equal to $9.78 per share. The number of settlement shares underlying the Additional SAR VI was calculated using the initial maximum settlement rate and, therefore, the number of shares underlying the Additional SAR VI is subject to adjustment and forfeiture if the aggregate number of shares of stock issued in settlement of any single Purchase Contract is less than the initial maximum settlement rate. Until each Purchase Contract settles and the voting common stock related thereto is issued, each corresponding Additional SAR VI has a vesting date of May 21, 2017 and has no dividend equivalent rights prior to vesting. The Additional SAR VI vests earlier as follows: (i) for any Purchase Contract settled before August 21, 2014, the Additional SAR VI corresponding to such Purchase Contract became two-third vested and exercisable on the date on which any such Purchase Contract was settled and the remaining one-third became vested and exercisable on August 21, 2014 and, until it became vested on August 21, 2014, the one-third unvested Additional SAR VI corresponding to such Purchase Contract was eligible for the same dividend equivalent rights as the Initial SAR; (ii) for any Purchase Contract settled in shares of voting common stock on or after August 21, 2014, then the Additional SAR VI corresponding to such Purchase Contract shall become 100 percent vested and exercisable on the date on which any such Purchase Contract is settled; and (iii) if the aggregate number of shares of voting common stock issued in settlement of any single Purchase Contract on the settlement date (the Actually Issued Common Shares) is less than the initial maximum settlement rate, then the Additional SAR VI related to that single Purchase Contract shall be recalculated and adjusted pursuant to the terms of the Initial SAR based on the Actually Issued Common Shares instead of the initial maximum settlement rate and the chief executive officer shall forfeit on such settlement date any Additional SAR VI granted in excess of those that would have been granted on the respective settlement date. The following table represents a summary of all outstanding SARs (Initial SAR and Additional SARs, together the SARs): Initial Additional SAR SAR I (1) II (2) III (3) IV (4) V (5) VI (6) VII (7) VIII (8) Grant Date 8/21/2012 6/21/2013 7/1/2013 7/2/2013 12/10/2013 5/21/2014 5/21/2014 11/7/2014 9/30/2015 Number of shares 500,000 150,933 88,366 15,275 70,877 252,023 266,349 216,334 2,973 Base price per share $ 12.12 $ 13.06 $ 13.60 $ 13.55 $ 12.83 $ 10.09 $ 10.09 $ 11.62 $ 12.27 Grant date fair value per share $ 2.77 $ 2.38 $ 2.17 $ 2.19 $ 2.47 $ 1.65 $ 2.22 $ 1.84 $ 1.72 (1) Issued due to the Company’s common stock issuance for an underwritten public offering completed on June 21, 2013. (2) Issued due to the Company’s common stock issuance in connection with the PBOC acquisition completed on July 1, 2013. (3) Issued due to the Company’s common stock issuance for the exercise of over-allotment option granted to the underwriters of the Company’s public common stock offering initially completed on June 21, 2013. (4) Issued due to the Company’s common stock issuance in a private placement completed on December 10, 2013. (5) Issued due to the Company’s common stock issuance for an underwritten public offering completed on May 21, 2014. (6) The Additional SAR VI originally related to 300,219 shares of common stock with a scheduled vesting of May 21, 2017 , as described above. As a result of the settlements of portions of the Purchase Contacts, the Additional SAR VI accelerated in vesting with respect to 230,391 shares and 33,870 shares were forfeited as of September 30, 2015 . A portion of Additional SAR VI that has accelerated in vesting has the same terms and conditions as the Initial SAR. (7) Issued due to the Company's common stock issuance completed on November 7, 2014. (8) Issued due to the Company's common stock issuance for the exercise of warrants on August 3, 2015. The SARs originally were to be settled in cash and the compensation expense for the SARs was recognized over the vesting period based on the fair value as calculated using Black Scholes as of the grant date and adjusted each quarter. On December 13, 2013 (the conversion date), the Company amended the Initial SAR agreement to provide that the SARs be settled in shares of voting common stock rather than cash, with all other terms remaining substantially the same. Currently, compensation expense is recognized over the vesting period based on the fair value as calculated using Black Scholes as of the conversion date for the SARs issued before the conversion date and grant dates for the SARs issued after the conversion date.

STOCKHOLDERS' EQUITY

STOCKHOLDERS' EQUITY	9 Months Ended

Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY Warrants On November 1, 2010, the Company issued warrants to TCW Shared Opportunity Fund V, L.P. for up to 240,000 shares of non-voting common stock at an original 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. These warrants were exercisable from the date of original issuance through November 1, 2015 . On August 3, 2015, these warrants were exercised in full using a cashless (net) exercise, resulting in a net number of shares of non-voting common stock issued in the aggregate of 70,690 , which were immediately thereafter exchanged for an aggregate of 70,690 shares of voting common stock. Based on automatic adjustments to the original $11.00 exercise price, the exercise price at the time of exercise was $9.13 per share. On November 1, 2010, the Company also issued warrants to COR Advisors LLC, 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, 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. As a result of transfers of these warrants subsequent to their original issuance, warrants for the right to purchase 960,000 shares of non-voting common stock are now held by Mr. Sugarman and his spouse through a living trust, and warrants for the right to purchase 435,000 shares of non-voting common stock are now held by Jeffrey T. Seabold, Executive Vice President and Chief Banking Officer of the Bank. These warrants vested in tranches, with the first tranche vesting on January 1, 2011 and the last tranche vesting on July 1, 2013 and with each respective tranche being exercisable for five years after the tranche's vesting date. Under the terms of the respective warrant agreements, the warrants are exercisable for voting common stock in lieu of non-voting common stock following the transfer of the warrants in a widely dispersed offering or in other limited circumstances. Based on automatic adjustments to the original $11.00 exercise price, the Company has determined that the exercise price for these warrants was $9.04 per share as of September 30, 2015 . The terms and issuance of the foregoing warrants were approved by the Company's stockholders at a special meeting held on October 25, 2010. Common Stock On May 21, 2014, the Company issued 5,150,000 shares of its voting common stock in an underwritten public offering and for gross proceeds of approximately $50.4 million and 772,500 shares of voting common stock upon the exercise in full by the underwriters of the underwritten public offering of their 30 -day over-allotment option, for additional gross proceeds of approximately $7.6 million . On November 7, 2014, the Company completed the issuance and sale of 3,288,947 shares of its voting common stock to OCM BOCA Investor, LLC (Oaktree), an entity owned by investment funds managed by Oaktree Capital Management, L.P., and 1,900,000 shares of its voting common stock to Patriot Financial Partners, L.P., Patriot Financial Partners Parallel, L.P., Patriot Financial Partners II, L.P. and Patriot Financial Partners Parallel II, L.P, for gross proceeds of $49.9 million . Preferred Stock On April 8, 2015, the Company completed the issuance and sale of 4,000,000 depositary shares, each representing a 1/40 th interest in a share of its 7.375 percent Non-Cumulative Perpetual Preferred Stock, Series D, liquidation preference of $1,000 per share (equivalent to $25.00 per depositary share), for gross proceeds of $96.9 million . The Company also granted the underwriters a 30 -day option to purchase up to an additional 600,000 depositary shares to cover over-allotments, which the underwriters exercised in full concurrently, resulting in additional gross proceeds of $14.5 million . Tangible Equity Units On May 21, 2014, the Company completed an underwritten public offering of 1,380,000 of its tangible equity units (TEUs), which included 180,000 TEUs issued to the underwriter upon the full exercise of its over-allotment option, resulting in net proceeds of $65.0 million . Each TEU is comprised of a prepaid stock purchase contract (each, a Purchase Contract) and a junior subordinated amortizing note due May 15, 2017 issued by the Company (each, an Amortizing Note). Unless settled early at the holder’s option, each Purchase Contract will automatically settle and the Company will deliver a number of shares of its voting common stock based on the then-applicable market value of the voting common stock, ranging from an initial minimum settlement rate of 4.4456 shares per Purchase Contract (subject to adjustment) if the applicable market value is equal to or greater than $11.247 per share to an initial maximum settlement rate of 5.1124 shares per Purchase Contract (subject to adjustment) if the applicable market value is less than or equal to $9.78 per share. From the first business day following the issuance of the TEUs to but excluding the third business day immediately preceding May 15, 2017, a holder of a Purchase Contract may settle its Purchase Contract early, and the Company will deliver to the holder 4.4456 shares of voting common stock. The holder also may elect to settle its Purchase Contract early in connection with a “fundamental change,” in which case the holder will receive a number of shares of voting common stock based on a fundamental change early settlement rate. The Company may elect to settle all Purchase Contracts early by delivering to each holder 5.1124 shares of voting common stock or, under certain circumstances, by delivering 4.4456 shares of voting common stock. As of September 30, 2015 , a total of 1,193,693 Purchase Contracts had been settled early by their holders, resulting in the issuance by the Company of 5,306,682 shares of voting common stock.

In addition to the risk-based guidelines, through December 31, 2014 the FRB required bank holding companies to maintain a minimum ratio of Tier 1 capital to average total assets, referred to as the leverage ratio, of 4.0 percent. Through December 31, 2014, in order to be considered “well capitalized,” federal bank regulatory agencies required depository institutions such as the Bank to maintain a minimum ratio of qualifying total capital to risk-weighted assets of 10.0 percent, a minimum ratio of Tier 1 capital to risk-weighted assets of 6.0 percent and a minimum ratio of Tier 1 capital to average total assets, referred to as the leverage ratio, of 5.0 percent. In July 2013, the Federal banking regulators approved a final rule to implement the revised capital adequacy standards of the Basel Committee on Banking Supervision, commonly called Basel III, and to address relevant provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act). The final rule strengthens the definition of regulatory capital, increases risk-based capital requirements, makes selected changes to the calculation of risk-weighted assets, and adjusts the prompt corrective action thresholds. The Company and the Bank became subject to the new rule on January 1, 2015 and certain provisions of the new rule will be phased in over the period of 2015 through 2019. The final rule: • Permits banking organizations that had less than $15 billion in total consolidated assets as of December 31, 2009, to include in Tier 1 capital trust preferred securities and cumulative perpetual preferred stock that were issued and included in Tier 1 capital prior to May 19, 2010, subject to a limit of 25 percent of Tier 1 capital elements, excluding any non-qualifying capital instruments and after all regulatory capital deductions and adjustments have been applied to Tier 1 capital. • Establishes new qualifying criteria for regulatory capital, including new limitations on the inclusion of deferred tax assets and mortgage servicing rights. • Requires a minimum ratio of common equity Tier 1 capital to risk-weighted assets of 4.5 percent. • Increases the minimum Tier 1 capital to risk-weighted assets ratio requirement from 4 percent to 6 percent. • Retains the minimum total capital to risk-weighted assets ratio requirement of 8 percent. • Retains a minimum leverage ratio requirement of 4 percent. • Changes the prompt corrective action standards so that in order to be considered well-capitalized, a depository institution must have a ratio of common equity Tier 1 capital to risk-weighted assets of 6.5 percent (new), a ratio of Tier 1 capital to risk-weighted assets of 8 percent (increased from 6 percent), a ratio of total capital to risk-weighted assets of 10 percent (unchanged), and a leverage ratio of 5 percent (unchanged). • Retains the existing regulatory capital framework for one-to-four family residential mortgage exposures. • Permits banking organizations that are not subject to the advanced approaches rule, such as the Company and the Bank, to retain, through a one-time election, the existing treatment for most accumulated other comprehensive income, such that unrealized gains and losses on securities available for sale will not affect regulatory capital amounts and ratios. • Implements a new capital conservation buffer requirement for a banking organization to maintain a common equity capital ratio more than 2.5 percent above the minimum common equity Tier 1 capital, Tier 1 capital and total risk based capital ratios in order to avoid limitations on capital distributions, including dividend payments, and certain discretionary bonus payments. The capital conservation buffer requirement will be phased in beginning on January 1, 2016 at 0.625 percent and will be fully phased in at 2.50 percent by January 1, 2019. A banking organization with a buffer of less than the required amount would be subject to increasingly stringent limitations on such distributions and payments as the buffer approaches zero. The new rule also generally prohibits a banking organization from making such distributions or payments during any quarter if its eligible retained income is negative and its capital conservation buffer ratio was 2.5 percent or less at the end of the previous quarter. The eligible retained income of a banking organization is defined as its net income for the four calendar quarters preceding the current calendar quarter, based on the organization’s quarterly regulatory reports, net of any distributions and associated tax effects not already reflected in net income. • Increases capital requirements for past-due loans, high volatility commercial real estate exposures, and certain short term commitments and securitization exposures. • Expands the recognition of collateral and guarantors in determining risk-weighted assets. • Removes references to credit ratings consistent with the Dodd Frank Act and establishes due diligence requirements for securitization exposures.

EARNINGS PER COMMON SHARE

EARNINGS PER COMMON SHARE	9 Months Ended

Earnings Per Share [Abstract]
EARNINGS PER COMMON SHARE	EARNINGS PER COMMON SHARE Net income allocated to common stockholders is computed by subtracting income allocated to participating securities, participating securities dividends and preferred stock dividends from net income. Participating securities are instruments granted in share-based payment transactions that contain rights to receive nonforfeitable dividends or dividend equivalents, which includes the SARs to the extent they confer dividend equivalent rights, as described under “Stock Appreciation Rights” in Note 14. Basic earnings per common share (EPS) is computed by dividing net income allocated to common stockholders by the weighted average number of shares outstanding, including the minimum number of shares issuable under purchase contracts relating to the tangible equity units. Diluted EPS is computed by dividing net income allocated to common stockholders by the weighted average number of shares outstanding, adjusted for the dilutive effect of the restricted stock units, the potentially issuable shares in excess of the minimum under purchase contracts relating to the tangible equity units, outstanding stock options, and warrants to purchase common stock. Computations for basic and diluted EPS are provided below.

SEGMENT REPORTING

SEGMENT REPORTING	9 Months Ended

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING The Company utilizes an internal reporting system to measure the performance of various operating segments within the Bank and the Company overall. The Company has identified four operating segments for purposes of management reporting: i) Commercial Banking; ii) Mortgage Banking; iii) Financial Advisory and Asset Management; and iv) Corporate/Other. Each of these four business divisions meets the criteria of an operating segment, as each segment engages in business activities from which it earns revenues and incurs expenses and its operating results are regularly reviewed by the Company’s chief operating decision-maker, the Company's President and Chief Executive Officer or his delegate, to make decisions about resources to be allocated to the segment and assess its performance and for which discrete financial information is available. The principal business of the Commercial Banking segment consists of attracting deposits and investing these funds primarily in commercial, consumer and real estate secured loans. The principal business of the Mortgage Banking segment is originating conforming SFR loans and selling these loans in the secondary market. The principal business of the Financial Advisory and Asset Management segment is operated by The Palisades Group and provides services of purchase, sale and management of SFR mortgage loans. The Corporate/Other segment includes the holding company and PTB, an entity formed to hold real estate. The Corporate/Other segment engages in business activities through the sale of other real estate owned and loans held at the holding company and incurs interest expense on debt as well as non-interest expense for corporate related activities. The operating segment results do not include allocation of centralized costs that are currently recorded in the Commercial Banking and Corporate/Other segment. The Company is currently in the process of determining the basis for calculating allocations. The following table represents the operating segments’ financial results and other key financial measures as of or for the three months ended September 30, 2015 and 2014 : As of or For the Three Months Ended Commercial Banking Mortgage Banking Financial Advisory and Asset Management Corporate/ Other Inter-segment Elimination Consolidated (In thousands) September 30, 2015 Net interest income $ 55,911 $ 3,606 $ — $ (3,967 ) $ — $ 55,550 Provision for loan and lease losses 735 — — — — 735 Noninterest income 14,669 33,843 3,072 — (857 ) 50,727 Noninterest expense 46,198 30,538 2,148 3,716 (857 ) 81,743 Income (loss) before income taxes $ 23,647 $ 6,911 $ 924 $ (7,683 ) $ — $ 23,799 Total assets $ 6,822,439 $ 418,877 $ 8,670 $ 175,173 $ (168,349 ) $ 7,256,810 September 30, 2014 Net interest income $ 37,801 $ 2,498 $ — $ (2,113 ) $ — $ 38,186 Provision for loan and lease losses 2,780 — — — — 2,780 Noninterest income 13,048 27,586 4,986 130 (1,652 ) 44,098 Noninterest expense 38,701 24,904 2,087 3,314 (1,652 ) 67,354 Income (loss) before income taxes $ 9,368 $ 5,180 $ 2,899 $ (5,297 ) $ — $ 12,150 Total assets $ 4,265,503 $ 271,700 $ 8,296 $ 66,585 $ (74,258 ) $ 4,537,826 The following table represents the operating segments’ financial results and other key financial measures as of or for the nine months ended September 30, 2015 and 2014 : As of or For the Nine Months Ended Commercial Banking Mortgage Banking Financial Advisory and Asset Management Corporate/ Other Inter-segment Elimination Consolidated (In thousands) September 30, 2015 Net interest income $ 162,352 $ 9,593 $ — $ (10,294 ) $ — $ 161,651 Provision for loan and lease losses 6,209 — — — — 6,209 Noninterest income 44,013 111,461 11,590 — (3,664 ) 163,400 Noninterest expense 136,925 94,218 8,160 9,903 (3,664 ) 245,542 Income (loss) before income taxes $ 63,231 $ 26,836 $ 3,430 $ (20,197 ) $ — $ 73,300 Total assets $ 6,822,439 $ 418,877 $ 8,670 $ 175,173 $ (168,349 ) $ 7,256,810 September 30, 2014 Net interest income $ 108,184 $ 6,181 $ — $ (5,419 ) $ — $ 108,946 Provision for loan and lease losses 6,817 — — — — 6,817 Noninterest income 25,940 72,345 11,508 209 (5,254 ) 104,748 Noninterest expense 103,495 71,094 6,817 9,100 (5,254 ) 185,252 Income (loss) before income taxes $ 23,812 $ 7,432 $ 4,691 $ (14,310 ) $ — $ 21,625 Total assets $ 4,265,503 $ 271,700 $ 8,296 $ 66,585 $ (74,258 ) $ 4,537,826

Related Party Transactions [Abstract]
RELATED-PARTY TRANSACTIONS	RELATED-PARTY TRANSACTIONS The Bank has granted loans to certain officers and directors and their related interests. Loans outstanding to officers and directors and their related interests amounted to $862 thousand and $200 thousand at September 30, 2015 and December 31, 2014 , respectively, each of which were performing in accordance with their respective terms. These loans are made in the ordinary course of business and on substantially the same terms and conditions, including interest rates and collateral, as those of comparable transactions with non-insiders prevailing at the time, in accordance with the Bank’s underwriting guidelines, and do not involve more than the normal risk of collectability or present other unfavorable features. The Bank has an Employee Loan Program (the Program) which offers executive officers, directors and principal stockholders that meet the eligibility requirements the opportunity to participate on the same terms as employees generally, provided that any loan to an executive officer, director or principal stockholder must be approved by the Bank’s Board of Directors. The sole benefit provided under the Program is a reduction in loan fees. Deposits from principal officers, directors, and their related interests amounted to $3.8 million and $4.5 million at September 30, 2015 and December 31, 2014 , respectively. Transactions Involving Steven A. Sugarman. The following is a description of transactions involving the Company and certain entities affiliated with or relatives of Steven A. Sugarman, President and Chief Executive Officer of the Company and the Bank and a member of the Board of Directors of the Company and the Bank. The Palisades Group Lease Payment Reimbursements. The Company acquired its subsidiary, The Palisades Group, LLC (The Palisades Group) on September 16, 2013, at which time Palisades occupied premises in Santa Monica, California leased by COR Securities Holding, Inc. (CORSHI), of which Mr. Sugarman is the Chief Executive Officer as well as a stockholder (both directly and indirectly). In light of the benefit received by The Palisades Group of its occupancy of the Santa Monica premises, the disinterested directors of the Company’s Board ratified reimbursement to CORSHI for rental payments made for the Santa Monica premises for the period commencing September 16, 2013 through June 27, 2014, the last date The Palisades Group occupied the premises. The Palisades Group negotiated with an unaffiliated third party a lease for new premises and occupied those premises on June 27, 2014. The aggregate amount of rent payments reimbursed to CORSHI from September 16, 2013 through December 30, 2013 were $40 thousand comprised of: (i) $6 thousand , the pro-rated base rent amount for the partial month of September 2013; (ii) $11 thousand per month in base rent for the months of October and November 2013; and (iii) $12 thousand per month in base rent for the month of December 2013. Regarding the security deposit for the premises, after The Palisades Group occupied the CORSHI premises, the Company reimbursed CORSHI relating to a security deposit amount for the premises of $34 thousand and the Company later received reimbursement of this security deposit amount from The Palisades Group. For the months of January 1, 2014 through June 27, 2014, CORSHI granted The Palisades Group a rent abatement equal to the $34 thousand security deposit and, combined with additional payments, The Palisades Group paid leasing costs totaling $58 thousand to CORSHI for that same time period. The Compensation, Nominating and Corporate Governance Committee of the Board has monitored all the reimbursement costs and reviewed the aggregate reimbursement costs. The Palisades Group Consulting Agreement. As discussed above, the Company acquired its subsidiary, The Palisades Group, on September 16, 2013. Effective July 1, 2013, The Palisades Group entered into a consulting agreement with Jason Sugarman, Mr. Sugarman’s brother.

On April 6, 2015, the Company issued $175.0 million aggregate principal amount of its 5.25 percent Senior Notes due April 15, 2025 in an underwritten public offering. Pursuant to a purchase agreement entered into with the Company on March 31, 2015, Keefe, Bruyette & Woods, Inc., acted as one of the underwriters of that offering and received gross underwriting fees and commissions from the Company of approximately $263 thousand for its services as an underwriter (less expenses, the amount was $221 thousand ).

Transactions with Greater Than 5 Percent Stockholders Who are Not Executive Officers Exchange Agreement with TCW Shared Opportunity Fund V, L.P. and its Assignees. TCW Shared Opportunity Fund V, L.P. (SHOP V Fund), an affiliate of The TCW Group, Inc., initially became a holder of the Company’s voting common stock and non-voting common stock as a lead investor in the November 2010 recapitalization of the Company (the Recapitalization). In connection with its investment in the Recapitalization, SHOP V Fund also was issued by the Company an immediately exercisable five -year warrant (the SHOP V Fund Warrant) to purchase 240,000 shares of non-voting common stock or, to the extent provided therein, shares of voting common stock in lieu of non-voting common stock. SHOP V Fund was issued shares of non-voting common stock in the Recapitalization because at that time, a controlling interest in TCW Asset Management Company, the investment manager to SHOP V Fund, was held by a foreign banking organization, and in order to prevent SHOP V Fund from being considered a bank holding company under the Bank Holding Company Act of 1956, as amended, the number of shares of voting common stock it purchased in the Recapitalization had to be limited to 4.99 percent of the total number of shares of voting common stock outstanding immediately following the Recapitalization. For the same reason, the SHOP V Fund Warrant could be exercised by SHOP V Fund for voting common stock in lieu of non-voting common stock only to the extent SHOP V Fund's percentage ownership of the voting common stock at the time of exercise would be less than 4.99 percent as a result of dilution occurring from additional issuances of voting common stock subsequent to the Recapitalization. In 2013, the foreign banking organization sold its controlling interest in TCW Asset Management Company, eliminating the need to limit SHOP V Fund's percentage ownership of the voting common stock to 4.99 percent. As a result, on May 29, 2013, the Company and SHOP V Fund entered into a Common Stock Share Exchange Agreement, dated May 29, 2013 (Exchange Agreement), pursuant to which SHOP V Fund may from time to time exchange its shares of non-voting common stock for shares of voting common stock issued by the Company on a share-for-share basis, provided that immediately following any such exchange, SHOP V Fund's percentage ownership of voting common stock does not exceed 9.99 percent. The shares of non-voting common stock that may be exchanged by SHOP V Fund pursuant to the Exchange Agreement include the shares of non-voting common stock it purchased in the Recapitalization, the additional shares of non-voting common stock SHOP V Fund acquired subsequent to the Recapitalization pursuant to the Company’s Dividend Reinvestment Plan and any additional shares of non-voting common stock that SHOP V Fund acquires pursuant to its exercise of the SHOP V Fund Warrant. On December 10, 2014, SHOP V Fund and two affiliated entities, Crescent Special Situations Fund Legacy V, L.P. (CSSF Legacy V) and Crescent Special Situations Fund Investor Group, L.P. (CSSF Investor Group), entered into a Contribution, Distribution and Sale Agreement pursuant to which SHOP V Fund agreed to transfer shares of non-voting common stock and portions of the SHOP V Fund Warrant to CSSF Legacy V and CSSF Investor Group. Also on December 10, 2014, SHOP V Fund, CSSF Legacy V, CSSF Investor Group and the Company entered into an Assignment and Assumption Agreement pursuant to which all of SHOP V Fund’s rights and obligations under the Exchange Agreement with respect to the shares of non-voting common stock transferred by it to CSSF Legacy V and CSSF Investor Group pursuant to the Contribution, Distribution and Sale Agreement were assigned to CSSF Legacy V and CSSF Investor Group, including the right of SHOP V Fund to exchange such shares for shares of voting common stock on a one -for-one basis. Based on an amended 13-G filed with the SEC on February 12, 2015, as of December 31, 2014, The TCW Group and its affiliates held 1,318,462 shares of voting common stock (which included, for purposes of the calculation, the 240,000 shares of stock underlying the as yet unexercised Shop V Fund Warrant). On June 3, 2013, January 5, 2015, January 20, 2015, and March 16, 2015, SHOP V Fund or CSSF Legacy V or CSSF Investor Group exchanged 550,000 shares, 522,564 shares, 86,620 shares, and 934 shares, respectively, of non-voting common stock for the same number of shares of voting common stock. In addition, on August 3, 2015, the SHOP V Fund Warrant, which was held in separate portions by CSSF Legacy V and CSSF Investor Group, was exercised in full using a cashless (net) exercise, resulting in a net number of shares of non-voting common stock issued in the aggregate of 70,690 , which were immediately thereafter exchanged for an aggregate of 70,690 shares of voting common stock. Based on automatic adjustments to the original $11.00 exercise price of the Shop V Fund Warrant, the exercise price at the time of exercise was $9.13 per share. As a result of these exchanges and exercises, as of September 30, 2015 The TCW Group, Inc. and its affiliates no longer held any shares of non-voting common stock or warrants to acquire stock.

In consideration for Patriot’s commitment under the New SPA and pursuant the terms of the New SPA, on the closing of the sale of such shares on November 7, 2014, the Company paid Patriot an equity support payment of $538 thousand and also reimbursed Patriot $100 thousand in out-of-pocket expenses. On October 30, 2014, concurrent with the execution of the New SPA, Patriot and the Company entered into a Settlement Agreement and Release (the Settlement Agreement) in order to resolve, without admission of any wrongdoing by either party, a prior dispute regarding, among other things, the proper interpretation of certain provisions of the SPA, including but not limited to the computation of the purchase price per share (the Dispute).

SUMMARY OF SIGNIFICANT ACCOUN31

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2015
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation: The accompanying unaudited consolidated financial statements include the accounts of Banc of California, Inc. (collectively, with its consolidated subsidiaries, the Company, we, us and our) and its wholly owned subsidiaries, Banc of California, National Association (the Bank), The Palisades Group, LLC (the Palisades Group), and PTB Property Holdings, LLC (PTB), as of September 30, 2015 and December 31, 2014 and for the three and nine months ended September 30, 2015 and 2014 . Significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiaries.
Basis of Presentation	Basis of Presentation: The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain disclosures required by 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, 2014 filed by the Company with the Securities and Exchange Commission. The December 31, 2014 balance sheet 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, 2014 filed with the Securities and Exchange Commission, but does not include all of the disclosures required by GAAP.
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 position and consolidated results of operations for the periods presented. Certain reclassifications have been made in the prior period financial statements to conform to the current period presentation.
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 financial statements and disclosures provided, and actual results could differ. The allowance for loan and lease losses, reserve for loss on repurchased loans, servicing rights, realization of deferred tax assets, the valuation of goodwill and other intangible assets, mortgage banking derivatives, purchased credit impaired loan discount accretion, fair value of assets and liabilities acquired in business combinations, and the fair value measurement of financial instruments are particularly subject to change and any such change could have a material effect on the consolidated financial statements.
Income Taxes	Income Taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax basis of assets and liabilities, computed using enacted tax rates. A valuation allowance is established when necessary to reduce deferred tax assets when it is more-likely-than-not that a portion or all of the net deferred tax assets will not be realized.
Allowance for Loan and Lease Losses	Allowance for Loan and Lease Losses: During the year ended December 31, 2014, the Company enhanced the methodologies, processes and controls over the allowance for loan and lease losses (ALLL), due to the Company's organic and acquisitive growth and changing profile. The following is a synopsis of the enhancements for each component of ALLL: • Expand the look-back period to 28 rolling quarters to capture the full economic cycle. • Utilize net historical losses versus gross historical losses. • Expand the peer group used to determine industry average loss history to include three industry groups: i) all U.S. financial and bank holding companies, ii) all California based financial and bank holding companies, and iii) the peer group average from the Uniform Bank Performance Report. • Apply the segment specific loss emergence period to each segment's loss. • Determine qualitative reserves at each loan segment level based on a baseline risk weighting adjusted for current risks, trends and business conditions. • Disaggregate certain qualitative factors to be determined on the portfolio segment level.
Accounting Pronouncements	In January 2014, the FASB issued ASU No. 2014-04, “Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.” ASU 2014-04 clarifies that an in substance repossession or foreclosure has occurred, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure. Interim and annual disclosure is required of both the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure. ASU 2014-04 is effective using either the modified retrospective transition method or a prospective transition method for fiscal years and interim periods within those years, beginning after December 15, 2014, and early adoption is permitted. Adoption of the new guidance did not have a significant impact on the Company’s consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing: Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.” The ASU changes the accounting for repurchase-to-maturity transactions to secured borrowing accounting. In addition, for repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The ASU also requires disclosures for certain transactions comprising (1) a transfer of a financial asset accounted for as a sale and (2) an agreement with the same transferee entered into in contemplation of the initial transfer that results in the transferor retaining substantially all of the exposure to the economic return on the transferred financial asset throughout the term of the transaction. There are additional disclosure requirements for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions that are accounted for as secured borrowings. Adoption of the new guidance did not have a significant impact on the Company’s consolidated financial statements. In August 2014, the FASB issued ASU 2014-14, “Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40), Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” Under ASU 2014-14, a mortgage loan should be derecognized and a separate receivable based on the principal and interest expected to be recovered from the governmental guarantor should be recognized upon foreclosure when all of the following conditions exist: a government guarantee exists that is not separable from the loan prior to the foreclosure; as of the date of the foreclosure the creditor has the intent to convey the real estate to the governmental agency that issued the guarantee, to make a claim on the guarantee and the creditor has the ability to recover amounts due from the governmental entity as a result of the claim; and, as of the time of the foreclosure, the claim amount that is based on the fair value of the real estate is fixed. ASU 2014-14 is effective using either the modified retrospective transition method or a prospective transition method for fiscal years and interim periods within those years, beginning after December 15, 2014. Adoption of the new guidance did not have a significant impact on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805), Simplifying the Accounting for Measurement-Period Adjustments.” This Update simplifies the accounting for adjustments made to provisional amounts recognized in a business combination, and eliminates the requirement to retrospectively account for those adjustments. The amendments to this Update require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The Updates require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments in this Update require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. For public business entities, the amendments to this Update are effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. This Update should be applied prospectively to adjustments to provisional amounts that occur after the effective date of this Update with earlier application permitted for financial statements that have not been issued. The Company early adopted the amendments to this Update during the current quarterly reporting period, ended September 30, 2015. The following are recently issued accounting pronouncements also applicable to the Company: In May 2014, the FASB issued ASU No. 2014-09, “Revenue From Contracts With Customers,” which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The ASU is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606),” which deferred the effective date of this ASU by one year. Therefore, ASU 2014-09 becomes effective for the Company for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-12, “Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” The ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis," which significantly changes the consolidation analysis required under U.S. GAAP. The new consolidation guidance maintains two models: one for assessing most corporate entities based on the notion that majority voting rights indicate control (the voting model) and another for assessing entities that may be controlled through other means, such as management contracts or subordinated financial support (the variable interest model). Under the new guidance, limited partnerships will be variable interest entities, unless the limited partners have either substantive kick-out or participating rights. There is no longer a presumption that a general partner should consolidate a limited partnership. The ASU also changes the effect that fees paid to a decision maker or service provider have on the consolidation analysis. For entities other than limited partnerships, the ASU clarifies how to determine whether the equity holders (as a group) have power over the entity. The ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. Early adoption is allowed for all entities, but the guidance must be applied as of the beginning of the annual period containing the adoption date. Entities have the option of using either a full or modified retrospective approach for adoption. The Company early adopted the amendments of this update during the current quarterly reporting period. Adoption of the new guidance did not have a significant impact on the Company's consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, "Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs," which requires the debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. The amendments in this ASU are to be applied on a retrospective basis. In August 2015, the FASB issued ASU 2015-15, "Interest-Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line of Credit Arrangements," which allows guidance in ASU 2015-03 to be applied to line of credit arrangements. The Company is in the process of assessing the impact of the new guidance on its consolidated financial statements. In January 2014, the FASB issued guidance within ASU 2014-01, “Accounting for Investments in Qualified Affordable Housing Projects," which amends ASC 323-720 to permit entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. The Company invests in qualified affordable housing projects (affordable housing fund investments) and previously accounted for them under the equity method of accounting. The Company recognized its share of partnership losses in noninterest expense with the tax benefit recognized in the income tax provision. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments are effective for fiscal years, and interim periods within those years, beginning after December 31, 2014 and should be applied retrospectively to all periods presented.
