SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	3 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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 subsidiary, Banc of California, National Association (the Bank), as of March 31, 2017 and December 31, 2016 and for the three months ended March 31, 2017 and 2016 . Significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its then wholly owned subsidiaries. Nature of Operations: Banc of California, Inc. is a financial holding company under the Bank Holding Company Act of 1956, as amended, headquartered in Santa Ana, California and incorporated under the laws of Maryland. Banc of California, Inc. is subject to regulation by the Board of Governors of the Federal Reserve System (FRB) and the Bank operates under a national bank charter issued by the Office of the Comptroller of the Currency (OCC), its primary regulator. The Bank is a member of the Federal Home Loan Bank (FHLB) system, and maintains insurance on deposit accounts with the Federal Deposit Insurance Corporation (FDIC). As of March 31, 2017 , the Bank had 37 banking offices, serving Orange, Los Angeles, San Diego, and Santa Barbara counties in California. 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 Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC. Refer to Accounting Pronouncements below for discussion of accounting pronouncements adopted in 2017 . Basis of Presentation: The accompanying unaudited interim consolidated financial statements have been prepared pursuant to Article 10 of SEC Regulation S-X and other SEC rules and regulations for reporting on 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, 2016 filed by the Company with the SEC. The December 31, 2016 statement of financial condition presented herein has been derived from the audited financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC, but does not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management of the Company, the accompanying unaudited interim consolidated financial statements reflect all of the adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial condition and consolidated results of operations as of the dates and for the periods presented. 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 months ended March 31, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017. During the three months ended March 31, 2017, the Company completed the sale of its Banc Home Loans division, which largely represented the Company's Mortgage Banking segment. In accordance with Accounting Standards Codification (ASC) 205-20, the Company determined that the sale of the Banc Home Loans division and certain other mortgage banking related assets and liabilities that will be sold or settled separately within one year met the criteria to be classified as a discontinued operation and its operating results and financial condition have been presented as discontinued operations in the consolidated financial statements (see Note 2 for additional information). Unless otherwise indicated, information included in these notes to the consolidated financial statements (unaudited) are presented on a consolidated operations basis, which includes results from both continuing and discontinued operations, for all periods presented. In connection with the sale of its Mortgage Banking segment, the Company reassessed its reportable operating segments. Based on this internal evaluation, the Company determined that all three of its previously disclosed reportable segments, Commercial Banking, Mortgage Banking, and Corporate/Other, are no longer applicable. Accordingly, to better reflect how the Company is now managed and how information is internally reviewed, the Company determined that all services offered by the Company relate to Commercial Banking and, as a result, its only reportable segment is Commercial Banking. 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 (ALLL), reserve for loss on repurchased loans, servicing rights, the valuation of goodwill and other intangible assets, derivative instruments, purchased credit impaired (PCI) loan discount accretion, 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. Incentive Compensation: At December 31, 2016 the Company accrued a liability for estimated discretionary incentive compensation payments to certain employees. The amount paid was less than the accrued liability. Consequently, the Company reversed the excess accrual and recorded a credit to salaries and employee benefits on the consolidated statements of operations of $7.8 million during the three months ended March 31, 2017. The reversal, based on new information driven by changes to certain facts and circumstances, was determined to be a change in estimate. 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 March 31, 2017 , the Company had net deferred tax assets of $18.7 million , with no valuation allowance and as of December 31, 2016 , the Company had net deferred tax assets of $10.0 million , with no valuation allowance. See Note 11 for additional information. Variable Interest Entities: The Company holds ownership interests in certain special purpose entities. The Company evaluates its interest in these entities to determine whether they meet the definition of a variable interest entity (VIE) and whether the Company is required to consolidate these entities. A VIE is consolidated by its primary beneficiary, the party that has both the power to direct the activities that most significantly impact the VIE and a variable interest that could potentially be significant to the VIE. A variable interest is a contractual, ownership or other interest that changes with changes in the fair value of the VIE’s net assets. To determine whether or not a variable interest could potentially be significant to the VIE, the Company considers both qualitative and quantitative factors regarding the nature, size and form of its involvement with the VIE. The Company performs analyses of whether the Company is the primary beneficiary of a VIE on an ongoing basis. Changes in facts and circumstances occurring since the previous primary beneficiary determination are considered as part of this ongoing assessment. See Note 17 for additional information. Alternative Energy Partnerships: The Company invests in certain alternative energy partnerships formed to provide sustainable energy projects that are designed to generate a return primarily through the realization of federal tax credits (energy tax credits). The Company is a limited partner in these partnerships, which were formed to invest in newly installed residential rooftop solar leases and power purchase agreements. The investment is recorded using a Hypothetical Liquidation at Book Value (HLBV) method. The Company uses the flow-through income statement method to account for the tax credits earned on investments in alternative energy partnerships. Under this method, the tax credits are recognized as a reduction to income tax expense and the initial book-tax differences in the basis of the investments are recognized as additional tax expense in the year they are earned. See Note 11 and 17 for additional information. Stock Employee Compensation Trust: The Company maintains a Stock Employee Compensation Trust (SECT) to fund future employee stock compensation and benefit obligations of the Company. The SECT holds and will release shares of the Company's common stock to be used to fund the Company's obligations during the term of the SECT under certain stock and other employee benefit plans of the Company. The Company accounts for and presents the shares held by the SECT as treasury stock. As the Company allocates the shares to the designated plans, the shares are released from the SECT, and the Company recognizes compensation expenses based on the fair value of the shares on the grant date. The SECT provides for confidential pass-through voting and tendering structured such that the individuals with an economic interest in the shares of the Company’s common stock held by the SECT control the voting and tendering of such shares. The 2,500,000 unallocated shares of the Company's common stock held by the SECT as of March 31, 2017 were not included in the weighted average number of common shares outstanding for purposes of calculating the Company's earnings per share (EPS). See Note 14, 15 and 17 for additional information. 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 Stock Appreciation Rights to the extent they confer dividend equivalent rights, as described under “Stock Appreciation Rights” in Note 14. Basic earnings per common share is computed by dividing net income allocated to common stockholders by the weighted average number of common shares outstanding, including the minimum number of shares issuable under purchase contracts relating to the tangible equity units, as described under "Tangible Equity Units" in Note 15. 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. For information regarding the tangible equity units, see Notes 10 and 15. Adopted Accounting Pronouncements: During the three months ended March 31, 2017 , the following pronouncement applicable to the Company was adopted: In March 2016, the FASB issued Accounting Standard Update (ASU) 2016-09, “ Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ” This Update was issued as a part of the FASB’s simplification initiative, and intends to improve the accounting for share-based payment transactions. The ASU changes several aspects of the accounting for share-based payment award transactions, including accounting for excess tax benefits and deficiencies, income statement recognition, cash flow classification, forfeitures, and tax withholding requirements. ASU 2016-09 is effective for public business entities in annual and interim periods in fiscal years beginning after December 15, 2016. Adoption of the new guidance did not have a significant impact on the Company's consolidated financial statements. See Note 11 for additional information. Recent Accounting Pronouncements Not Yet Adopted: The following are recently issued accounting pronouncements applicable to the Company that have not yet been adopted: In February 2016, the FASB issued ASU 2016-02, “ Leases (Topic 842) .” The amendments in this Update require lessees to recognize the assets and liabilities that arise from leases, as well as define classification criteria for distinguishing between financing leases and operating leases. This Update requires lessees to recognize all leases on the Consolidated Statement of Financial Condition as lease assets and lease liabilities based primarily on the present value of future lease payments. Lessor accounting is largely unchanged. A modified retrospective approach is required at adoption which requires all prior periods presented in the financial statements to be restated, with a cumulative effect adjustment to retained earnings as of the beginning of the earliest period presented. This guidance also requires additional disclosures regarding leasing arrangements. For public business entities, the amendments to this Update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption of the amendments in this Update is permitted. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In May 2016, the FASB issued ASU 2016-12, “ Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. ” This Update amends the guidance in ASU 2014-09, Revenue from Contracts with Customers , and clarifies the collectability criteria, accounting policy elections, noncash consideration, satisfied and unsatisfied performance obligations, completed contracts, and disclosures. The amendments in ASU 2016-12 affect the guidance in ASU 2014-09, which is effective for public business entities in annual and interim reporting periods beginning after December 15, 2017. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. As this ASU is not applicable to financial instruments, it will not impact the Company's major portion of revenue, net interest income, and the Company does not expect this guidance to have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, " Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. " The amendments in this Update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For public business entities that are SEC filers, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. The impact of this Update will depend upon the state of the economy and the nature of the Company's portfolio at the date of adoption. In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business.” The amendments in this Update provide a guidance on evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Currently, Topic 805 does not specify the minimum inputs and processes required for a set to meet the definition of a business. This Update presents a more robust framework to use when an entity determines whether a set of assets and activities represents a business. Also, this Update sets forth more consistency in applying the guidance with a more operable definition of a business. Public business entities must prospectively apply the amendments in this Update to annual periods beginning after December 15, 2017, including interim periods. The Company does not expect this guidance to have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” The amendments in this Update eliminate Step 2 from the goodwill impairment test when it is required. Instead, an entity must perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. For an impairment charge, an entity must recognize impairment by which the carrying amount exceeds the reporting unit’s fair value, but the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Furthermore, this Update requires an entity to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. Public business entities that are SEC filers must adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal year beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In February 2017, the FASB issued ASU 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets.” The amendments in this Update clarify the scope and application of ASC 610-20 on the sale or transfer of nonfinancial assets, including real estate, and in substance nonfinancial assets to noncustomers, including partial sales. An entity should identify each distinct nonfinancial asset or in substance nonfinancial asset promised to a counterparty and derecognize each asset when a counterparty obtains control of it. An in substance nonfinancial asset is an asset within a contract or subsidiary in which substantially all of the fair value of the asset is concentrated in a nonfinancial asset. In addition, the amendment requires an entity to derecognize a distinct nonfinancial asset or in substance nonfinancial asset in a partial sale transaction when the entity does not retain a controlling financial interest in the legal entity that holds the asset and an entity transfers control of the asset. Once control is transferred, any non-controlling interest received is required to be measured at fair value. The effective date of the new guidance is aligned with the requirements in the new revenue standard, which is effective for public business entities in annual and interim reporting periods beginning after December 15, 2017. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." The amendments in this Update shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount, which continue to be amortized to maturity. Public business entities must prospectively apply the amendments in this Update to annual periods beginning after December 15, 2018, including interim periods. The Company does not expect this guidance to have a material impact on its consolidated financial statements.

SALES OF SUBSIDIARY AND BUSINES

Discontinued Operations and Disposal Groups [Abstract]
SALES OF SUBSIDIARY AND BUSINESS UNITS	SALES OF SUBSIDIARY AND BUSINESS UNITS The Palisades Group Sale On May 5, 2016, the Company completed the sale of all of its membership interests in The Palisades Group, a wholly owned subsidiary of the Company, to an entity wholly owned by Stephen Kirch and Jack Macdowell the then-acting Chief Executive Officer and Chief Investment Officer of The Palisades Group, respectively. As part of the sale, The Palisades Group issued to the Company a 10 percent , $5.0 million note due May 5, 2018 (the Note). The Company recognized a gain on sale of subsidiary of $3.7 million on its Consolidated Statements of Operations for the three months ended June 30, 2016. The following table summarizes the calculation of the gain on sale of The Palisades Group: Three Months Ended June 30, 2016 (In thousands) Consideration received (paid) Liabilities forgiven by The Palisades Group $ 1,862 Liabilities assumed by the Company (1,078 ) The Note 2,370 Aggregate fair value of consideration received 3,154 Less: net assets sold (carrying amount of The Palisades Group) (540 ) Gain on sale of The Palisades Group $ 3,694 The Company estimated various potential future cash flow projection scenarios for The Palisades Group and established probability thresholds for each scenario to arrive at a probability-weighted cash flow expectation, which was then discounted to yield a fair value of the Note at sale date of $2.4 million . On September 28, 2016, the Note was paid in full in cash prior to maturity and the Company recognized an additional gain of $2.8 million , which was included in Other Income in the Consolidated Statements of Operations for the three months ended September 30, 2016. Commercial Equipment Finance Business Sale On October 27, 2016, the Company sold its Commercial Equipment Finance business unit from its Commercial Banking segment to Hanmi Bank, a wholly-owned subsidiary of Hanmi Financial Corporation (Hanmi). As part of the transaction, Hanmi acquired $217.2 million of equipment leases diversified across the U.S. with concentrations in California, Georgia and Texas. An additional $25.4 million of equipment leases were transferred during December 2016. Hanmi retained most of the Company’s former Commercial Equipment Finance employees. The Company recorded a gain on sale of business unit of $2.6 million in its Consolidated Statements of Operations for the three months ended December 31, 2016. Banc Home Loans Sale On March 30, 2017, the Company completed the sale of specific assets related to its Banc Home Loans division to Caliber Home Loans, Inc. (Caliber). The Banc Home Loans division represented the Company's Mortgage Banking segment, the activities of which related to originating, processing, underwriting, funding and selling residential mortgage loans. Assets sold to Caliber included mortgage servicing rights (MSRs) on certain conventional agency residential mortgage loans. The Banc Home Loans division, along with certain other mortgage banking related assets and liabilities that will be sold or settled separately within one year, is classified as discontinued operations in the accompanying Consolidated Statements of Financial Condition and Consolidated Statements of Operations. Certain components of the Company’s Mortgage Banking segment including MSRs on certain conventional government SFR mortgage loans that were not sold as part of the Banc Home Loans sale, and the repurchase reserves related to previously sold loans, have been classified as continuing operations in the financial statements as they will continue to be part of the Company’s ongoing operations. The specific assets acquired by Caliber include, among other things, the leases relating to the Company’s dedicated mortgage loan origination offices and rights to certain portions of the Company’s unlocked pipeline of residential mortgage loan applications. Caliber has assumed certain obligations and liabilities of the Company under the acquired leases, and with respect to the employment of transferred employees. The Company received a $25.0 million cash premium payment, in addition to the net book value of certain assets acquired by Caliber, totaling $2.5 million , upon closing of the transaction. The Company may receive up to an additional $5.0 million cash premium based on criteria tied to loan officer retention by Caliber. Additionally, the Company could receive an earn-out, payable quarterly, based on future performance over the 38 months following completion of the transaction. Caliber retains an option to buy out the future earn-out payable to the Company in exchange for cash consideration of $35.0 million , less the aggregate amount of all earn-out payments made prior to the date on which Caliber makes the payment of the buyout amount. Caliber also purchased the MSRs of $37.8 million on approximately $3.86 billion in unpaid balances of conventional agency mortgage loans, subject to adjustment under certain circumstances. The transaction resulted in a net gain of disposal of $13.3 million . The Banc Home Loans division originated conforming SFR mortgage loans and sold these loans in the secondary market. The amount of net revenue on mortgage banking activities was a function of mortgage loans originated for sale and the fair values of these loans and related derivatives. Net revenue on mortgage banking activities included mark to market pricing adjustments on loan commitments and forward sales contracts, and initial capitalized value of MSRs. The following table summarizes the calculation of the net gain on disposal of discontinued operations: Three Months Ended March 31, 2017 (In thousands) Proceeds from the transaction $ 63,332 Compensation expense related to the transaction (4,000 ) Other transaction costs (3,703 ) Net cash proceeds 55,629 Book value of certain assets sold (2,455 ) MSRs sold (37,772 ) Goodwill (2,100 ) Net gain on disposal $ 13,302 The following tables present the financial information of discontinued operations as of the dates or for the periods indicated: Statements of Financial Condition of Discontinued Operations March 31, December 31, (In thousands) ASSETS Loans held-for-sale, carried at fair value (1) $ 420,449 $ 406,338 Loans held-for-sale, carried at lower of cost or fair value 682 295 Servicing rights carried at fair value — 37,681 Premises, equipment, and capital leases, net — 2,700 Goodwill — 2,100 Other assets 11,674 33,380 Assets of discontinued operations $ 432,805 $ 482,494 LIABILITIES Accrued expenses and other liabilities (1) $ 30,309 $ 34,480 Liabilities of discontinued operations $ 30,309 $ 34,480 (1) Includes $20.0 million and $16.5 million of GNMA loans, respectively, that are delinquent more than 90 days and subject to a repurchase option by the Company at March 31, 2017 and December 31, 2016. As such, the Company is deemed to have regained control over those previously transferred assets and has re-recognized them with an offsetting liability recognized in Accrued Expenses and Other Liabilities in the Statements of Financial Condition of Discontinued Operations, as a secured borrowing. Because the Company intends to exercise its option to repurchase and sell them within one year, they have been classified as part of discontinued operations.

FAIR VALUES OF FINANCIAL INSTRU

FAIR VALUES OF FINANCIAL INSTRUMENTS	3 Months Ended
	Mar. 31, 2017
Fair Value Disclosures [Abstract]
FAIR VALUES OF FINANCIAL INSTRUMENTS	FAIR VALUES OF FINANCIAL INSTRUMENTS Fair Value Hierarchy ASC 820-10 establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The topic describes three levels of inputs that may be used to measure fair value: • Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2: Significant observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Assets and Liabilities Measured on a Recurring Basis Securities Available-for-Sale: The fair values of securities available-for-sale are generally determined by quoted market prices in active markets, if available (Level 1). If quoted market prices are not available, the Company primarily employs independent pricing services that utilize pricing models to calculate fair value. Such fair value measurements consider observable data such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and respective terms and conditions for debt instruments. The Company employs procedures to monitor the pricing service's assumptions and establishes processes to challenge the pricing service's valuations that appear unusual or unexpected. Level 2 securities include Small Business Administration (SBA) loan pool securities, U.S. government sponsored entity (GSE) and agency securities, private label residential mortgage-backed securities, agency residential mortgage-backed securities, non-agency commercial mortgage-backed securities, collateralized loan obligations, 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 March 31, 2017 or December 31, 2016 . 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, except for loans that are repurchased out of Ginnie Mae loan pools that become severely delinquent which are valued based on an internal model that estimates the expected loss the Company will incur on these loans. Therefore, loans held-for-sale subjected to recurring fair value adjustments are classified as Level 2 or, in the case of loans repurchased out of Ginnie Mae loan pools, Level 3. The fair value includes the servicing value of the loans as well as any accrued interest. Derivative Assets and Liabilities : Derivative Instruments Related to Mortgage Banking Activities: The Company 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. These commitments are classified as Level 2 in the fair value disclosures, as the valuations are based on market observable inputs. The Company hedges the risk of the overall change in the fair value of loan commitments to borrowers with forward loan sale commitments and trades in to-be-announced (TBA) mortgage-backed securities of GSEs. These forward settling contracts are classified as Level 2, as valuations are based on market observable inputs. Fair values of these derivatives are included assets and liabilities of discontinued operations. Interest Rate Swaps and Caps: The Company offers interest rate swaps and caps products to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The fair value of these derivatives is based on a discounted cash flow approach. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of interest rate swaps is classified as Level 2. Foreign Exchange Contracts: The Company offers short-term foreign exchange contracts to its customers to purchase and/or sell foreign currencies at set rates in the future. These products allow customers to hedge the foreign exchange rate risk of their deposits and loans denominated in foreign currencies. In conjunction with these products the Company also enters into offsetting contracts with institutional counterparties to hedge the Company’s foreign exchange rate risk. These back-to-back contracts allow the Company to offer its customers foreign exchange products while minimizing its exposure to foreign exchange rate fluctuations. The fair value of these instruments is determined at each reporting period based on the change in the foreign exchange rate. Given the short-term nature of the contracts, the counterparties’ credit risks are considered nominal and resulted in no adjustments to the valuation of the short-term foreign exchange contracts. Due to the observable nature of the inputs used in deriving the fair value of these derivative contracts, the valuation of these contracts is classified as Level 2. Mortgage Servicing Rights: The Company retains servicing on some of its mortgage loans sold for which the Company elected to follow the fair value measurement method for subsequent accounting. 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. The following table presents the Company’s financial assets and liabilities measured at fair value on a recurring basis as of March 31, 2017 : Fair Value Measurement Level Carrying Value Quoted Prices Significant Significant (In thousands) Assets Securities available-for-sale: SBA loan pools securities $ 1,145 $ — $ 1,145 $ — Private label residential mortgage-backed securities 116,757 — 116,757 — Corporate bonds 19,144 — 19,144 — Collateralized loan obligation 1,502,253 — 1,502,253 — Agency mortgage-backed securities 795,242 — 795,242 — Loans held-for-sale, carried at fair value (1) 422,144 — 355,443 66,701 Mortgage servicing rights (2) 42,833 — — 42,833 Derivative assets: Interest rate lock commitments (3) 9,813 — 9,813 — Mandatory forward commitments (3) 153 — 153 — Interest rate swaps and caps (4) 1,099 — 1,099 — Foreign exchange contracts (4) — — — — Liabilities Derivative liabilities: Interest rate lock commitments (5) 81 — 81 — Mandatory forward commitments (5) 2,909 — 2,909 — Interest rate swaps and caps (6) 1,096 — 1,096 — Foreign exchange contracts (6) — — — — (1) Includes loans held-for-sale carried at fair value of $420.4 million ( $353.7 million at Level 2 and $66.7 million at Level 3) of discontinued operations, which are included in Assets of Discontinued Operations in the Consolidated Statements of Financial Condition (2) Included in Servicing Rights, Net in the Consolidated Statements of Financial Condition (3) Included in Assets of Discontinued Operations in the Consolidated Statements of Financial Condition (4) Included in Other Assets in the Consolidated Statements of Financial Condition (5) Included in Liabilities of Discontinued Operations in the Consolidated Statements of Financial Condition (6) Included in Accrued Expenses and Other Liabilities in the Consolidated Statements of Financial Condition The following table presents the Company’s financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2016 : Fair Value Measurement Level Carrying Value Quoted Prices Significant Significant (In thousands) Assets Securities available-for-sale: SBA loan pools securities $ 1,221 $ — $ 1,221 $ — Private label residential mortgage-backed securities 117,177 — 117,177 — Corporate bonds 48,948 — 48,948 — Collateralized loan obligation 1,406,869 — 1,406,869 — Agency mortgage-backed securities 807,273 — 807,273 — Loans held-for-sale, carried at fair value (1) 416,974 — 358,714 58,260 Mortgage servicing rights (2) 76,121 — — 76,121 Derivative assets Interest rate lock commitments (3) 8,317 — 8,317 — Mandatory forward commitments (3) 8,897 — 8,897 — Interest rate swaps and caps (4) 707 — 707 — Foreign exchange contracts (4) 47 — 47 — Liabilities Derivative liabilities Interest rate lock commitments (5) 231 — 231 — Mandatory forward commitments (5) 1,212 — 1,212 — Interest rate swaps and caps (6) 655 — 655 — Foreign exchange contracts (6) 18 — 18 — (1) Includes loans held-for-sale carried at fair value of $406.3 million ( $348.1 million at Level 2 and $58.3 million at Level 3) of discontinued operations, which are included in Assets of Discontinued Operations in the Consolidated Statements of Financial Condition.

The following table presents, as of the dates indicated, quantitative information about Level 3 fair value measurements on a recurring basis, other than loans that become severely delinquent and are repurchased out of Ginnie Mae loan pools that were valued based on an estimate of the expected loss the Company will incur on these loans, which was included as Level 3 at March 31, 2017 and December 31, 2016 : Fair Value Valuation Technique(s) Unobservable Input(s) Range (Weighted Average) ($ in thousands) March 31, 2017 Mortgage servicing rights $ 42,833 Discounted cash flow Discount rate 9.25% to 15.00% (10.95%) Prepayment rate 7.00% to 37.80% (12.83%) December 31, 2016 Mortgage servicing rights (1) $ 76,121 Discounted cash flow Discount rate 9.11% to 15.00% (10.18%) Prepayment rate 7.00% to 39.90% (11.84%) (1) Includes $37.7 million of MSRs of discontinued operations The significant unobservable inputs used in the fair value measurement of the Company’s servicing rights include the discount rate and prepayment rate. The significant unobservable inputs used in the fair value measurement of the Company's loans repurchased from Ginnie Mae pools at March 31, 2017 and December 31, 2016 included an expected loss rate of 1.55 percent . There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. Fair Value Option Loans Held-for-Sale, Carried at Fair Value: The Company elected to measure certain SFR mortgage loans held-for-sale under the fair value option. Electing to measure SFR mortgage loans held-for-sale at fair value reduces certain timing differences and better matches changes in the value of these assets with changes in the value of derivatives used as economic hedges for these assets. The following table presents the fair value and aggregate principal balance of certain assets, on a consolidated operations basis, under the fair value option: March 31, 2017 December 31, 2016 Fair Value Unpaid Principal Balance Difference Fair Value Unpaid Principal Balance Difference (In thousands) Loans held-for-sale, carried at fair value in continuing operations: Total loans $ 1,695 $ 1,671 $ 24 $ 10,636 $ 10,606 $ 30 Nonaccrual loans — — — — — — Loans past due 90 days or more and still accruing — — — — — — Loans held-for-sale, carried at fair value in discontinued operations: Total loans $ 420,449 $ 408,318 $ 12,131 $ 406,338 $ 397,283 $ 9,055 Nonaccrual loans 56,731 57,216 (485 ) 54,151 54,824 (673 ) Loans past due 90 days or more and still accruing — — — — — — The assets and liabilities accounted for under the fair value option are initially measured at fair value. Gains and losses from initial measurement and subsequent changes in fair value are recognized in earnings. The following table presents changes in fair value related to initial measurement and subsequent changes in fair value included in earnings for these assets and liabilities measured at fair value for the periods indicated: Three Months Ended March 31, 2017 2016 (In thousands) Net gains from fair value changes Net gain on sale of loans (continuing operations) $ 24 $ 55 Net revenue on mortgage banking activities (discontinued operations) $ 10,793 $ 14,173 Changes in fair value due to instrument-specific credit risk were insignificant for the three months ended March 31, 2017 and 2016. Interest income on loans held-for-sale under the fair value option is measured based on the contractual interest rate and reported in Loans and Leases, including Fees under Interest and Dividend Income and Income from Discontinued Operations in the Consolidated Statements of Operations. 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 amortized 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 independent pricing services that utilize pricing models to calculate fair value. Such fair value measurements consider observable data such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and respective terms and conditions for debt instruments (Level 2). 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 March 31, 2017 . Impaired Loans and Leases: The fair value of impaired loans and leases with specific allocations of the ALLL 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 and certain non-residential mortgage loans held-of-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 $9 thousand and $0 , respectively, for the three months ended March 31, 2017 and 2016 in All Other Expense in the Consolidated Statements of Operations.

Federal Home Loan Bank and Other Bank Stock: Federal Home Loan Bank 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: 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 independent pricing services that utilize pricing models to calculate fair value. Such fair value measurements consider observable data such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and respective terms and conditions for debt instruments (Level 2). 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. Loans and Leases Receivable, Net of ALLL: 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. 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). This method of estimating fair value does not incorporate the exit-price concept of fair value prescribed by ASC Topic 820. 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, Securities Sold under Repurchase Agreements, and Other Borrowings: The fair values of advances from FHLB, securities sold under repurchase agreements, and other borrowings 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.

At March 31, 2017 , the Company’s securities available-for-sale portfolio consisted of 163 securities, 52 of which were in an unrealized loss position and securities held-to-maturity consisted of 84 securities, 16 of which were in an unrealized loss position. At December 31, 2016, the Company’s securities available-for-sale portfolio consisted of 161 securities, 59 of which were in an unrealized loss position and securities held-to-maturity consisted of 87 securities, 15 of which were in an unrealized loss position. The fair value of securities held-to-maturity improved at March 31, 2017 mainly due to tighter credit spreads at March 31, 2017 and improvement in the economic sectors for the bond issuers. The fair value of securities available-for-sale declined slightly at March 31, 2017 mainly due to changes in market interest rates. The Company monitors its securities portfolio to ensure it has adequate credit support. As of March 31, 2017 , the Company believed there was no OTTI and did not have the intent to sell these securities and, for securities with amortized cost below fair value at March 31, 2017, it is not likely that it will be required to sell the securities before their anticipated recovery. The Company considers the lowest credit rating for identification of potential OTTI. As of March 31, 2017 , all of the Company's investment securities in an unrealized loss position received an investment grade credit rating.

As of March 31, 2017 and December 31, 2016 , the NTM loans totaled $818.0 million , or 13.4 percent of total loans and leases, and $885.1 million , or 14.7 percent of total loans and leases, respectively. The total NTM portfolio decreased by $67.1 million , or 7.6 percent , during the three months ended March 31, 2017 . The following table presents the composition of the NTM portfolio as of the dates indicated: March 31, 2017 December 31, 2016 Count Amount Percent Count Amount Percent ($ in thousands) Green Loans (HELOC) - first liens 104 $ 85,665 10.5 % 107 $ 87,469 9.9 % Interest-only - first liens 480 725,005 88.6 % 522 784,364 88.6 % Negative amortization 11 3,791 0.5 % 22 9,756 1.1 % Total NTM - first liens 595 814,461 99.6 % 651 881,589 99.6 % Green Loans (HELOC) - second liens 12 3,549 0.4 % 12 3,559 0.4 % Total NTM - second liens 12 3,549 0.4 % 12 3,559 0.4 % Total NTM loans 607 $ 818,010 100.0 % 663 $ 885,148 100.0 % Total loans and leases $ 6,105,321 $ 6,034,752 % of NTM to total loans and leases 13.4 % 14.7 % Green Loans Green Loans are SFR first and second mortgage lines of credit with a linked checking account that allows all types of deposits and withdrawals to be performed. The loans are generally interest only with a 15 year-balloon payment due at maturity. At March 31, 2017 and December 31, 2016 , Green Loans totaled $89.2 million and $91.0 million , respectively. At March 31, 2017 and December 31, 2016 , none of the 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 (LTV) 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 SFR first mortgage loans with payment features that allow interest only payments in initial periods before converting to a fully amortizing loan. At March 31, 2017 and December 31, 2016 , interest only loans totaled $725.0 million and $784.4 million , respectively. As of March 31, 2017 and December 31, 2016 , $468 thousand and $467 thousand of the interest only loans were non-performing, respectively. Loans with the Potential for Negative Amortization Negative amortization loans other than Green Loans totaled $3.8 million and $9.8 million at March 31, 2017 and December 31, 2016 , respectively. The Company discontinued origination of negative amortization loans in 2007. At March 31, 2017 and December 31, 2016 , 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 LTV ratios. Risk Management of Non-Traditional Mortgages The Company has determined that significant performance indicators for NTMs are LTV ratios and Fair Isaac Corporation (FICO) scores. Accordingly, the Company manages credit risk in the NTM portfolio through periodic review of the loan portfolio that includes refreshing FICO scores on the Green Loans and other home equity lines of credit (HELOCs), as needed in conjunction with portfolio management, and ordering third party automated valuation models (AVMs). 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 score of 10 percent or more and/or a resulting FICO score 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 periodic 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 score 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. 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 March 31, 2017 by FICO scores that were obtained during the quarter ended March 31, 2017 , comparing to the FICO scores for those same loans that were obtained during the quarter ended December 31, 2016: March 31, 2017 By FICO Scores Obtained During the Quarter Ended March 31, 2017 By FICO Scores Obtained During the Quarter Ended December 31, 2016 Change Count Amount Percent Count Amount Percent Count Amount Percent ($ in thousands) FICO Score 800+ 16 $ 11,841 13.8 % 16 $ 9,371 11.0 % — $ 2,470 2.8 % 700-799 57 43,049 50.3 % 52 41,742 49.5 % 5 1,307 0.8 % 600-699 22 21,933 25.6 % 28 27,332 31.2 % (6 ) (5,399 ) (5.6 )% <600 2 3,422 4.0 % 1 1,800 2.1 % 1 1,622 1.9 % No FICO 7 5,420 6.3 % 7 5,420 6.2 % — — 0.1 % Totals 104 $ 85,665 100.0 % 104 $ 85,665 100.0 % — $ — — % Loan-to-Value Ratio LTV ratio represents estimated current loan to value ratio, determined by dividing current unpaid principal balance by latest estimated property value received per the Company policy.

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 ALLL, and partial or full charge-off. The Company maintains the ALLL 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 separate 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. At March 31, 2017 and December 31, 2016 , the reserve for unfunded loan commitments was $3.2 million and $2.4 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 loan and lease losses. The Board of Directors also provides oversight and guidance for management’s allowance evaluation process. During the three months ended March 31, 2017, the Company, as part of its continuous evaluation of the ALLL methodology and assumptions, determined it appropriate to change from a rolling 28 -quarter look-back period to a pegged 36 -quarter look-back period. This update to the assumption did not have a material impact. The Company believes that an extended period of observed credit loss stability warranted the review of a longer historical period that captured a full credit cycle. The determination of the amount of the ALLL 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 considers known relevant internal and external factors that affect collectability when determining the appropriate level for the ALLL. Additions to the ALLL 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 ALLL. Recoveries of previously charged off amounts, if any, are credited to the ALLL. The following table presents a summary of activity in the ALLL for the periods indicated: Three Months Ended March 31, 2017 2016 (In thousands) Balance at beginning of period $ 40,444 $ 35,533 Loans and leases charged off (357 ) (102 ) Recoveries of loans and leases previously charged off 66 93 Provision for loan and lease losses 2,583 321 Balance at end of period $ 42,736 $ 35,845 The following table presents the activity and balance in the ALLL and the recorded investment, excluding accrued interest, in loans and leases based on the impairment methodology as of or for the three months ended March 31, 2017 : Commercial and Industrial Commercial Real Estate Multi- family SBA Construction Lease Financing Single Family Residential Mortgage Other Consumer Total (In thousands) ALLL: Balance at December 31, 2016 $ 7,584 $ 5,467 $ 11,376 $ 939 $ 2,015 $ 6 $ 12,075 $ 982 $ 40,444 Charge-offs (250 ) — — — — — (81 ) (26 ) (357 ) Recoveries — — — 43 — 19 1 3 66 Provision 3,554 (924 ) (347 ) 164 1,003 (20 ) (755 ) (92 ) 2,583 Balance at March 31, 2017 $ 10,888 $ 4,543 $ 11,029 $ 1,146 $ 3,018 $ 5 $ 11,240 $ 867 $ 42,736 Individually evaluated for impairment $ — $ — $ — $ — $ — $ — $ 250 $ — $ 250 Collectively evaluated for impairment 10,888 4,538 11,029 1,127 3,018 5 10,853 867 42,325 Acquired with deteriorated credit quality — 5 — 19 — — 137 — 161 Total ending ALLL balance $ 10,888 $ 4,543 $ 11,029 $ 1,146 $ 3,018 $ 5 $ 11,240 $ 867 $ 42,736 Loans: Individually evaluated for impairment $ — $ — $ — $ — $ 1,528 $ — $ 10,984 $ 883 $ 13,395 Collectively evaluated for impairment 1,580,969 749,440 1,449,715 73,433 140,636 285 1,832,818 124,931 5,952,227 Acquired with deteriorated credit quality 4,687 1,152 — 2,607 — — 131,253 — 139,699 Total ending loan balances $ 1,585,656 $ 750,592 $ 1,449,715 $ 76,040 $ 142,164 $ 285 $ 1,975,055 $ 125,814 $ 6,105,321 The following table presents the activity and balance in the ALLL and the recorded investment, excluding accrued interest, in loans and leases based on the impairment methodology as of or for the three months ended March 31, 2016 : Commercial and Industrial Commercial Real Estate Multi- family SBA Construction Lease Financing Single Family Residential Mortgage Other Consumer Total (In thousands) ALLL: Balance at December 31, 2015 $ 5,850 $ 4,252 $ 6,012 $ 683 $ 1,530 $ 2,195 $ 13,854 $ 1,157 $ 35,533 Charge-offs — — — — — (102 ) — — (102 ) Recoveries — — — 31 — 61 — 1 93 Provision 196 (283 ) 472 192 (10 ) 456 (584 ) (118 ) 321 Balance at March 31, 2016 $ 6,046 $ 3,969 $ 6,484 $ 906 $ 1,520 $ 2,610 $ 13,270 $ 1,040 $ 35,845 Individually evaluated for impairment $ 29 $ — $ — $ — $ — $ — $ 1,347 $ — $ 1,376 Collectively evaluated for impairment 5,959 3,857 6,484 887 1,520 2,610 11,906 1,040 34,263 Acquired with deteriorated credit quality 58 112 — 19 — — 17 — 206 Total ending ALLL balance $ 6,046 $ 3,969 $ 6,484 $ 906 $ 1,520 $ 2,610 $ 13,270 $ 1,040 $ 35,845 Loans: Individually evaluated for impairment $ 4,493 $ 299 $ — $ — $ — $ — $ 34,296 $ 294 $ 39,382 Collectively evaluated for impairment 978,649 705,176 1,021,097 68,700 68,241 212,836 1,576,150 108,861 4,739,710 Acquired with deteriorated credit quality 819 8,218 — 2,940 — — 671,999 — 683,976 Total ending loan balances $ 983,961 $ 713,693 $ 1,021,097 $ 71,640 $ 68,241 $ 212,836 $ 2,282,445 $ 109,155 $ 5,463,068 The following table presents loans and leases individually evaluated for impairment by class of loans and leases as of the dates indicated.

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. The following table summarizes the pre-modification and post-modification balances of the new TDRs for the periods indicated: Three Months Ended Number of Loans Pre- Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment ($ in thousands) March 31, 2017 Consumer: Single family residential mortgage 2 $ 1,266 $ 1,273 Total 2 $ 1,266 $ 1,273 March 31, 2016 Consumer: Single family residential mortgage 38 $ 9,173 $ 9,173 Total 38 $ 9,173 $ 9,173 The following table summarizes the TDRs by modification type for the periods indicated: Three Months Ended Modification Type Change in Principal Payments and Interest Rates Change in Principal Payments Change in Interest Rates Total Count Amount Count Amount Count Amount Count Amount ($ in thousands) March 31, 2017 Consumer: Single family residential mortgage 1 $ 130 1 $ 1,143 — $ — 2 $ 1,273 Total 1 $ 130 1 $ 1,143 — $ — 2 $ 1,273 March 31, 2016 Consumer: Single family residential mortgage 32 $ 8,220 5 $ 875 1 $ 78 38 $ 9,173 Total 32 $ 8,220 5 $ 875 1 $ 78 38 $ 9,173 For the three months ended March 31, 2017 , there was one loan with a principal balance of $124 thousand that was modified as a TDR during the past 12 months that had payment defaults during the period.

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. 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”. 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 : 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 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, LTV ratios, 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.

SERVICING RIGHTS

SERVICING RIGHTS	3 Months Ended
	Mar. 31, 2017
Transfers and Servicing [Abstract]
SERVICING RIGHTS	SERVICING RIGHTS The Company retains 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. On a consolidated operations basis, total income (loss) from servicing rights was $4.3 million and $(5.3) million , respectively, for the three months ended March 31, 2017 and 2016 . The Company recognized losses on the fair value and runoff of servicing rights of $1.9 million and $10.2 million , respectively, for the three months ended March 31, 2017 and 2016 . The Company recognized servicing fees of $6.2 million and $4.9 million , respectively, for the three months ended March 31, 2017 and 2016 . These amounts are reported in Loan Servicing Income (Loss) in the Consolidated Statements of Operations. During the year ended December 31, 2016, the Company entered into a flow-agreement establishing general terms for the purchase and sale to a third party MSR investor in connection with residential mortgage loan sales to GSEs. The flow-agreement allowed the Company to sell its MSRs to a third party MSR investor contemporaneous with the Company’s sales of its servicing retained residential mortgages to the GSEs. Accordingly, entering into the flow-agreement reduced the impact of volatility associated with the Company's MSRs by allowing the Company to sell its MSRs immediately, thus reducing the Company's exposure to market and other conditions. During the three months ended March 31, 2017, the Company suspended sales of MSRs under the flow-agreement. The Company does not expect to resume sales under the flow-agreement, as the Company has discontinued its Mortgage Banking segment operations. The following table presents a composition of servicing rights, on a consolidated operations basis, as of the dates indicated: March 31, December 31, (In thousands) Mortgage servicing rights, at fair value $ 42,833 $ 76,121 SBA servicing rights, at cost 1,618 1,496 Total $ 44,451 $ 77,617 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 March 31, 2017 and December 31, 2016 was $4.15 billion and $7.58 billion , respectively. Custodial escrow balances maintained in connection with serviced loans were $14.9 million and $34.2 million at March 31, 2017 and December 31, 2016 , respectively. The reductions in these balances were principally driven by the sale of $37.8 million of MSRs during the three months ended March 31, 2017 recognized as discontinued operations.

The portion of the issuance costs allocated to the debt component of the TEUs is being amortized over the term of the Amortizing Notes. See Note 15 for additional information.

INCOME TAXES

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES For the three months ended March 31, 2017 and 2016 , income tax (benefit) expense, on a consolidated operations basis, was $(948) thousand and $13.3 million , respectively, and the effective tax rate was (5.8) percent and 40.3 percent , respectively. The Company’s effective tax rate was lower in the 2017 period primarily due to the recognition of year-to-date tax credits from the investments in alternative energy partnerships of approximately $8.8 million . The Company uses the flow-through income statement method to account for the investment tax credits earned on the solar investments. Under this method, the investment tax credits are recognized as a reduction to income tax expense and the initial book-tax difference in the basis of the investments are recognized as additional tax expense in the year they are earned. The Company accounts for income taxes by recognizing deferred tax assets and liabilities based upon temporary differences between the amounts for financial reporting purposes and tax basis of its assets and liabilities. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In assessing the realization of deferred tax assets, management will continue to evaluate both positive and negative evidence on a quarterly basis, including the 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 net deferred tax assets of $18.7 million and $10.0 million at March 31, 2017 and December 31, 2016 , respectively. ASC 740-10-25 relates to the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. ASC 740-10-25 prescribes a threshold and a measurement process for recognizing in the financial statements a tax position taken or expected to be taken in a tax return and also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company had no unrecognized tax benefits at March 31, 2017 and December 31, 2016 . At March 31, 2017 and December 31, 2016 , the Company had no accrued interest or penalties. In the event the Company is assessed interest and/or penalties by federal or state tax authorities, such amounts will be classified in the consolidated financial statements as income tax expense. The Company and its subsidiaries are subject to U.S. Federal income tax as well as income tax in multiple state jurisdictions. The Company is no longer subject to the assessment of U.S. federal income tax for years before 2013.The statute of limitations for the assessment of California Franchise taxes has expired for tax years before 2012 (other state income and franchise tax statutes of limitations vary by state). The Company adopted ASU 2016-09 during the three months ended March 31, 2017. As a result of the adoption, the Company recorded $391 thousand of income tax benefits for the three months ended March 31, 2017 related to excess tax benefits from stock compensation. Prior to 2017, such excess tax benefits were generally recorded directly in stockholders’ equity. This new accounting standard may potentially increase the volatility in the Company’s effective tax rates.

RESERVE FOR LOSS ON REPURCHASED LOANS	RESERVE FOR LOSS ON REPURCHASED LOANS 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 $517 thousand and $379 thousand for the three months ended March 31, 2017 and 2016 , respectively. Of these total provisions for loan repurchases, the Company recorded an initial provision for loan repurchases of $842 thousand and $738 thousand , respectively, for the three months ended March 31, 2017 and 2016 against Net Revenue on Mortgage Banking Activities in the Statement of Operations of discontinued operations. In addition, the Company recorded a reversal for loan repurchase reserve in noninterest expense of $325 thousand and $359 thousand , respectively, for the three months ended March 31, 2017 and 2016 . The following table presents a summary of activity in the reserve for losses on repurchased loans for the periods indicated: Three Months Ended March 31, 2017 2016 (In thousands) Balance at beginning of period $ 7,974 $ 9,700 Provision for loan repurchases 517 379 Utilization of reserve for loan repurchases (373 ) (298 ) Balance at end of period $ 8,118 $ 9,781 In addition to the reserve for losses on repurchased loans at March 31, 2017 , the Company may receive repurchase demands in future periods that could be material to the Company's financial position or results of operations. The Company believes that all known or probable and estimable demands were adequately reserved for at March 31, 2017 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS The Company uses derivative instruments and other risk management techniques to reduce its exposure to adverse fluctuations in interest rates and foreign currency exchange rates in accordance with its risk management policies. Derivative Instruments Related to Mortgage Banking Activities: In connection with mortgage banking activities, if interest rates increase, the value of the Company’s loan commitments to borrowers and 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 with forward loan sale contracts and TBA mortgage-backed securities trades. Forward contracts on loan sale commitments, TBA mortgage-based securities trades, 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 Statement of Operations of discontinued operations. The fair value of resulting derivative assets and liabilities are included in Other Assets and Accrued Expenses and Other Liabilities, respectively, in the Statement of Financial Condition of discontinued operations. The net losses relating to these derivative instruments used for mortgage banking activities, which were included in Net Revenue on Mortgage Banking Activities in the Statement of Operations of discontinued operations, were $324 thousand and $6.3 million , respectively, for the three months ended March 31, 2017 and 2016 . Interest Rate Swaps on Deposits and Other Borrowings: 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 year ended December 31, 2016, the Company terminated all of its interest rate swaps, which had an aggregate notional amount of $75.0 million . Interest Rate Swaps and Caps on Loans: The Company offers interest rate swap and cap products to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. These swaps and caps are not designated as hedging instruments and are recorded at fair value in Other Assets and Accrued Expenses and Other Liabilities in the Consolidated Statement of Financial Condition. The changes in fair value are recorded in Other Income in the Consolidated Statements of Operations. For the three months ended March 31, 2017 , changes in fair value recorded through Other Income in the Consolidated Statements of Operations were insignificant. Foreign Exchange Contracts: The Company offers short-term foreign exchange contracts to its customers to purchase and/or sell foreign currencies at set rates in the future. These products allow customers to hedge the foreign exchange rate risk of their deposits and loans denominated in foreign currencies. In conjunction with these products the Company also enters into offsetting contracts with institutional counterparties to hedge the Company’s foreign exchange rate risk. These back-to-back contracts allow the Company to offer its customers foreign exchange products while minimizing its exposure to foreign exchange rate fluctuations. These foreign exchange contracts are not designated as hedging instruments and are recorded at fair value in Other Assets and Accrued Expenses and Other Liabilities in the Consolidated Statement of Financial Condition. At March 31, 2017 , the Company had no outstanding foreign exchange contracts. The following table presents the notional amount and fair value of derivative instruments included in the Consolidated Statements of Financial Condition as of the dates indicated. Note 3 contains further disclosures pertaining to the fair value of mortgage banking derivatives.

The Company has entered into agreements with counterparty financial institutions, which include master netting agreements that provide for the net settlement of all contracts with a single counterparty in the event of default. However, the Company elected to account for all derivatives with counterparty institutions on a gross basis. Due to clearinghouse rule changes, beginning January 1, 2017, variation margin payments are treated as settlements of derivative exposure rather than as collateral.

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 period (generally ranging from one to five years ) of continued service from the date of grant plus, in some cases, the satisfaction of performance conditions. 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 months ended March 31, 2017 : Three Months Ended March 31, 2017 Number of Weighted Average Grant Date Fair Value Per Share Outstanding at beginning of period 1,417,144 $ 16.16 Vested (302,842 ) $ 18.95 Forfeited (57,881 ) $ 14.85 Outstanding at end of period 1,056,421 $ 15.43 Stock Appreciation Rights On August 21, 2012, the Company granted to Steven A. Sugarman, its then- (now former) 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 with one-third of the Initial SAR being vested on the grant date and the remaining amount vesting over a period of 2 years . The Initial SAR entitles Mr. Sugarman to dividend equivalent rights and originally contained an anti-dilution provision pursuant to which additional SARs (Additional SARs) were issued to Mr. Sugarman upon certain stock issuances by the Company, as described below. On March 24, 2016, concurrent with entering into a new employment agreement with the Company, Mr. Sugarman entered into a letter agreement that eliminated this anti-dilution provision of the Initial SAR. Under the terms of the March 24, 2016 letter agreement, in consideration of the removal of the anti-dilution provision of the Initial SAR, the Company granted Mr. Sugarman a onetime performance based restricted stock award with an aggregate grant date fair market value of $5.0 million , which would vest in full on March 24, 2017, but was also subject to restrictions on sale or transfer through March 24, 2021. In connection with Mr. Sugarman’s resignation as the Company’s chief executive officer on January 23, 2017, all unvested equity awards (including any unvested SARs) immediately vested and became free of all restrictions. In addition, the SARs continued (and continue) to remain exercisable for their full terms, with dividend equivalent rights of the SARs also continuing in effect during their full terms. As described more fully in the SAR agreement, the original anti-dilution provision of the Initial SAR did not apply to certain issuances of the Company’s common stock for compensatory purposes, but did apply to certain other issuances of the Company’s common stock, including the issuances of common stock to raise capital. Pursuant to this anti-dilution provision, the Company issued Additional SARs to the former chief executive officer with a base price determined as of each date of issuance, but otherwise with the same terms and conditions as the Initial SAR, except for an Additional SAR granted relating to a public offering of the Company’s TEU on May 21, 2014 that has different terms (Additional TEU SAR). Regarding the Additional TEU SAR, the TEU contains a prepaid stock purchase contract (Purchase Contract) that can be settled in shares of the Company’s voting common stock based on a maximum settlement rate (subject to adjustment) and a minimum settlement rate (subject to adjustment) as more fully described under Note 15. The Additional TEU SAR was calculated using the initial maximum settlement rate and, therefore, the number of shares underlying the Additional TEU SAR are 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. By its original terms, the Additional TEU SAR was to vest in full on May 15, 2017 or accelerate in vesting upon early settlement of a Purchase Contract at the holders' option, and until it vested, the Additional TEU SAR was to have no dividend equivalent rights and the shares underlying the Additional TEU SAR were subject to forfeiture.

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 (and resigned from those and all other positions with the Company and the Bank on January 23, 2017), 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. Subsequent to their original issuance, warrants for the right to purchase 960,000 shares of non-voting common stock were transferred to Steven A. Sugarman and his spouse through a living trust, and warrants for the right to purchase 435,000 shares of non-voting common stock were transferred to Jeffrey T. Seabold, Executive Vice President and Management Vice-Chair. These warrants vested in tranches, with each tranche being exercisable for five years after the tranche's vesting date. With respect to the warrants transferred to Steven A. Sugarman, 50,000 shares vested on October 1, 2011 and the remainder vested in seven equal quarterly installments beginning January 1, 2012 and ending on July 1, 2013. With respect to the warrants transferred to Mr. Seabold, 95,000 shares vested on January 1, 2011; 130,000 shares vested on each of April 1 and July 1, 2011, and 80,000 shares vested on October 1, 2011. On August 17, 2016, Steven A. Sugarman and his spouse through their living trust transferred warrants to purchase 480,000 shares to Steven A. Sugarman's brother, Jason Sugarman. The living trust transferred the warrants in consideration for certain consulting services Jason Sugarman previously rendered to COR Advisors LLC. The transferred warrants are last exercisable on September 30, 2016, December 31, 2016, March 31, 2017, June 30, 2017 and September 30, 2017 for 50,000 , 130,000 , 130,000 , 130,000 , and 40,000 shares respectively. On August 17, 2016, Jason Sugarman irrevocably elected to fully exercise each tranche of the transferred warrant. Under the irrevocable election, Jason Sugarman directed that each such exercise would occur on the last exercisable date for each tranche using a cashless (net) exercise method and also directed that each exercise be for either non-voting common stock, or, if allowed under the terms of the warrant, for voting common stock. At September 30, 2016, December 31, 2016, and March 31, 2017 , based on Jason Sugarman’s irrevocable election, warrants to purchase 50,000 , 130,000 , and 130,000 shares, respectively, had been exercised, resulting in issuances of 25,051 and 64,962 shares of the Company's voting common stock and 75,875 shares of the Company's class B non-voting common stock, respectively. Steven A. Sugarman and his spouse through the living trust continue to hold warrants to purchase 480,000 shares, which are last exercisable on September 30, 2017, December 31, 2017, March 31, 2018 and June 30, 2018 for 90,000 , 130,000 , 130,000 and 130,000 shares respectively. On December 8, 2015, March 9, 2016, June 17, 2016, and September 30, 2016, Mr. Seabold exercised his warrants with respect to 95,000 , 130,000 , 130,000 , and 80,000 shares, respectively, using cashless (net) exercises, resulting in a net number of shares of non-voting common stock issued in the aggregate of 37,355 , 53,711 , 70,775 , and 40,081 , respectively. Based on automatic adjustments to the original $11.00 exercise price, the exercise price at the time of exercise was $9.04 , $8.90 , $8.84 , and $8.80 per share, respectively. As a result of these exercises, Mr. Seabold no longer holds warrants to purchase shares of non-voting common stock. Under the terms of the respective warrants, the warrants are exercisable for voting common stock in lieu of non-voting common stock following a transfer of the warrants under certain circumstances described in the terms of the warrants. Based on automatic adjustments to the original $11.00 exercise price, the Company has determined that the exercise price for the warrants was $8.66 per share as of March 31, 2017 . 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 March 8, 2016 , the Company issued and sold 4,850,000 shares of its voting common stock in an underwritten public offering, for gross proceeds of approximately $66.5 million . On the same date, the Company issued an additional 727,500 shares of voting common stock upon the exercise in full by the underwriters of their 30 -day over-allotment option, for additional gross proceeds of approximately $10.5 million . On May 11, 2016 , the Company issued and sold 5,250,000 shares of its voting common stock in an underwritten public offering for gross proceeds of approximately $100.0 million . Stock Employee Compensation Trust On August 3, 2016, the Company and Evercore Trust Company, N.A., as trustee, established the Banc of California Capital and Liquidity Enhancement Employee Compensation Trust (the SECT) to fund future employee compensation and benefit obligations of the Company using the Company’s common stock. On August 3, 2016, pursuant to a Common Stock Purchase Agreement between the Company and the SECT, the Company sold 2,500,000 shares of the Company’s common stock to the SECT for an aggregate purchase price of $53.6 million , in exchange for a cash amount equal to the aggregate par value of the shares and a promissory note for the balance of the purchase price. The SECT will release the shares over the term of the SECT to satisfy certain compensatory and benefit obligations of the Company under certain stock and other employee benefit plans of the Company and its subsidiaries, as the promissory note is paid down through allocations of available shares as directed by the Company, dividends on the shares received by the SECT or other earnings of the SECT. As the shares are released from the SECT and allocated to the plans, the Company recognizes compensation expense based on the fair value of the shares on the grant date. The unallocated shares of the Company's common stock held by the SECT are not included in calculating the Company's earnings per share. All shares held by the SECT were unallocated at March 31, 2017 . The SECT provides for confidential pass-through voting and tendering structured such that the individuals with an economic interest in the shares of the Company’s common stock held by the SECT control the voting and tendering of such shares. The SECT will terminate on January 1, 2032 or any earlier date on which the promissory note is paid in full. The Board of Directors may also terminate the SECT at any earlier time, and the SECT will terminate automatically upon the Company giving the trustee notice of a change of control of the Company. Preferred Stock The Company is authorized to issue 50,000,000 shares of preferred stock with par value of $0.01 . Preferred shares outstanding rank senior to common shares both as to dividends and liquidation preference but have no voting rights. All of the Company's outstanding shares of preferred stock have a $1,000 per share liquidation preference. The following table presents the Company's total authorized, issued and outstanding preferred stock as of dates indicated: March 31, 2017 December 31, 2016 Shares Authorized and Outstanding Liquidation Preference Carrying Value Shares Authorized and Outstanding Liquidation Preference Carrying Value ($ in thousands) Series C 8.00% non-cumulative perpetual 40,250 $ 40,250 $ 37,943 40,250 $ 40,250 $ 37,943 Series D 7.375% non-cumulative perpetual 115,000 115,000 110,873 115,000 115,000 110,873 Series E 7.00% non-cumulative perpetual 125,000 125,000 120,255 125,000 125,000 120,255 Total 280,250 $ 280,250 $ 269,071 280,250 $ 280,250 $ 269,071 On February 8, 2016, the Company completed the issuance and sale, in an underwritten public offering, of 5,000,000 depositary shares, each representing a 1/40 th interest in a share of its 7.00 percent Non-Cumulative Perpetual Preferred Stock, Series E (with 125,000 shares of Series E Non-Cumulative Perpetual Preferred Stock issued), with a liquidation preference of $1,000 per share (equivalent to $25 per depositary share), for gross proceeds of $121.1 million . On April 1, 2016, the Company completed the redemption of all 32,000 outstanding shares of the Company's Non-Cumulative Perpetual Preferred Stock, Series A, and all 10,000 outstanding shares of the Company's Non-Cumulative Perpetual Preferred Stock, Series B. The shares were redeemed at a redemption price equal to the liquidation amount of $1,000 per share plus the unpaid dividends for the current dividend period to, but excluding, the redemption date. Both the Series A Preferred Stock and the Series B preferred Stock were issued as part of the U.S. Department of the Treasury's Small Business Lending Fund Program. 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 March 31, 2017 , a total of 1,342,600 Purchase Contracts had been settled early by their holders, resulting in the issuance by the Company of 5,951,762 shares of voting common stock. As of March 31, 2017 , 37,400 Purchase Contracts remained outstanding. Each Amortizing Note has an initial principal amount of $10.604556 per Amortizing Note, bears interest at a rate of 7.50 percent per annum and has a scheduled final installment payment date of May 15, 2017. On each August 15, November 15, February 15 and May 15, commencing on August 15, 2014, the Company will pay holders of Amortizing Notes equal quarterly cash installments of $1.00 per Amortizing Note (or, in the case of the installment payment due on August 15, 2014, $0.933333 per Amortizing Note) (such installments, the installment payments), which installment payments in the aggregate will be equivalent to a 8.00 percent cash distribution per year with respect to each $50.00 stated amount of TEUs. Each installment payment will constitute a payment of interest (at a rate of 7.50 percent per annum) and a partial repayment of principal on each Amortizing Note. The Company has the right to defer installment payments at any time and from time to time, subject to certain restrictions, so long as such deferral period does not extend beyond May 15, 2019 . If the Company elects to settle the Purchase Contracts early, the holders of the Amortizing Notes will have the right to require the Company to repurchase the Amortizing Notes. As of March 31, 2017 and December 31, 2016 , the Amortizing Notes, net of unamortized discounts, totaled $1.3 million and $2.7 million , respectively, net of unamortized discounts, and were included in Long Term Debt in the Consolidated Statements of Financial Condition.

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 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, with additional 0.625 percent increments annually, 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.

VARIABLE INTEREST ENTITIES

VARIABLE INTEREST ENTITIES	3 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES T he Company holds ownership interests in alternative energy partnerships and the SECT. The Company evaluates its interests in these entities to determine whether they meet the definition of a VIE and whether the Company is required to consolidate these entities. A VIE is consolidated by its primary beneficiary, which is the party that has both (i) the power to direct the activities that most significantly impact the economic performance of the VIE and (ii) a variable interest that could potentially be significant to the VIE. To determine whether or not a variable interest the Company holds could potentially be significant to the VIE, the Company considers both qualitative and quantitative factors regarding the nature, size and form of the Company's involvement with the VIE. The Company has determined that its interests in these entities meet the definition of a variable interest. Unconsolidated VIEs The Company invests in certain alternative energy partnerships (limited liability companies) formed to provide sustainable energy projects that are designed to generate a return primarily through the realization of federal tax credits (energy tax credits). These entities were formed to invest in newly installed residential rooftop solar leases and power purchase agreements. As a result of its investments, the Company has the right to certain investment tax credits and tax depreciation benefits (recognized on the flow through and income statement method in accordance with ASC 740), and to a lesser extent, cash flows generated from the installed solar systems leased to individual consumers for a fixed period of time. While the Company's interest in the alternative energy partnerships meets the definition of a VIE in accordance with ASC 810, the Company has determined that the Company is not the primary beneficiary because the Company does not have the power to direct the activities that most significantly impact the economic performance of the entities including operational and credit risk management activities. As the Company is not the primary beneficiary, the Company did not consolidate the entities. The Company uses the HLBV method to account for its investments in energy tax credits as an equity investment under ASC 970-323-25-17. Under the HLBV method, an equity method investor determines its share of an investee's earnings by comparing its claim on the investee's book value at the beginning and end of the period, assuming the investee were to liquidate all assets at their U.S. GAAP amounts and distribute the resulting cash to creditors and investors under their respective priorities. The Company funded $30.9 million into the partnerships and recognized a loss on investment of $8.7 million through its HLBV application during the three months ended March 31, 2017 . As a result, the balance of its investments were $47.6 million at March 31, 2017 . The Company has funded $88.3 million of its $200.0 million aggregate funding commitments. From an income tax benefit perspective, the Company recognized investment tax credits of $8.8 million as well as income tax benefits relating to the recognition of its loss through its HLBV application during the three months ended March 31, 2017 . As the investments represent unconsolidated VIEs to the Company, the assets and liabilities of the investments themselves are not recorded on the Company's statements of financial condition. The following table represents the carrying value of the associated assets and liabilities and the associated maximum loss exposure for the unconsolidated VIEs as of the dates indicated: March 31 December 31 (In thousands) Cash $ 224 $ — Equipment, net of depreciation 203,226 151,721 Other assets 8,337 351 Total unconsolidated assets $ 211,787 $ 152,072 Total unconsolidated liabilities $ 651 $ — Maximum loss exposure $ 159,365 $ 68,298 The maximum loss exposure that would be absorbed by the Company in the event that all of the assets in the VIEs are deemed worthless is $159.4 million , consisting of the investment balance of $47.6 million and $111.7 million of unfunded equity commitments at March 31, 2017 . The Company believes that the loss exposure on its investment is reduced considering its return on its investment is provided not only by the cash flows of the underlying customer leases and power purchase agreements, but also through the significant tax benefits, including federal tax credits generated from the investments. In addition, the arrangements include a transition manager to support any transition of the solar company sponsor whose role includes that of the servicer and operation and maintenance provider, in the event the sponsor would be required to be removed from its responsibilities (e.g., bankruptcy, breach of contract, etc.), thereby further limiting the Company’s exposure. Consolidated VIE The Company maintains a SECT to fund future employee stock compensation and benefit obligations of the Company. The SECT holds and will release shares of the Company's common stock to be used to fund the Company's obligations during the term of the SECT under certain stock and other employee benefit plans of the Company. During the three months ended September 30, 2016, the Company sold 2,500,000 shares of the Company’s common stock to the SECT for an aggregate purchase price of $53.6 million , in exchange for a cash amount equal to the aggregate par value of the shares and a promissory note for the balance of the purchase price. The promissory note is paid down through allocations of available shares to the Company’s stock and other employee benefit plans as directed by the Company, dividends on the shares received by the SECT, other earnings of the SECT, or may be forgiven by the Company. The Company evaluated its interest in the SECT and determined it is a VIE of which the Company is the primary beneficiary. As such, the SECT is consolidated by the Company. The entire amount of assets and liabilities of the SECT represents the transactions between the Company and the SECT. As a result, the note receivable on the Company and the note payable on the SECT are eliminated on a consolidated basis. All other transactions, such as note principal and dividend payments and receipts, are also eliminated on a consolidated basis, accordingly. See Note 15 for additional information.

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

In exchange for the Bank’s rights as set forth in the agreements, the Bank agreed to pay LAFC $100.0 million over a period of 15 years , beginning in 2017 and ending in 2032. As of March 31, 2017, the Company paid $10.0 million of the commitment, which was recognized as a prepaid assets and included in Other Assets in Consolidated Statements of Financial Condition.

Litigation From time to time we are involved as plaintiff or defendant in various legal actions arising in the normal course of business. The Company was named as a defendant in several complaints filed in the United States District Court for the Central District of California in January 2017 alleging violations of sections 10(b) and 20(a) of the Securities Exchange Act of 1934. The complaints were brought as purported class actions on behalf of stockholders who purchased shares of the Company’s common stock between varying dates, inclusive of August 7, 2015 through January 23, 2017. In general, the complaints allege that the Company’s alleged concealment of its purported relationship with an individual who pled guilty to securities fraud in matters unrelated to the Company caused various statements made by the Company to be allegedly false and misleading. These legal actions are at a very early stage. The Company intends to vigorously defend such actions.

SUMMARY OF SIGNIFICANT ACCOUN33

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2017
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 subsidiary, Banc of California, National Association (the Bank), as of March 31, 2017 and December 31, 2016 and for the three months ended March 31, 2017 and 2016 . Significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its then wholly owned subsidiaries.
Basis of Presentation	Basis of Presentation: The accompanying unaudited interim consolidated financial statements have been prepared pursuant to Article 10 of SEC Regulation S-X and other SEC rules and regulations for reporting on 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, 2016 filed by the Company with the SEC. The December 31, 2016 statement of financial condition presented herein has been derived from the audited financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC, but does not include all of the disclosures required by GAAP for complete financial statements.
Reclassification	In the opinion of management of the Company, the accompanying unaudited interim consolidated financial statements reflect all of the adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial condition and consolidated results of operations as of the dates and for the periods presented. 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 (ALLL), reserve for loss on repurchased loans, servicing rights, the valuation of goodwill and other intangible assets, derivative instruments, purchased credit impaired (PCI) loan discount accretion, 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.
Variable Interest Entities	Variable Interest Entities: The Company holds ownership interests in certain special purpose entities. The Company evaluates its interest in these entities to determine whether they meet the definition of a variable interest entity (VIE) and whether the Company is required to consolidate these entities. A VIE is consolidated by its primary beneficiary, the party that has both the power to direct the activities that most significantly impact the VIE and a variable interest that could potentially be significant to the VIE. A variable interest is a contractual, ownership or other interest that changes with changes in the fair value of the VIE’s net assets. To determine whether or not a variable interest could potentially be significant to the VIE, the Company considers both qualitative and quantitative factors regarding the nature, size and form of its involvement with the VIE. The Company performs analyses of whether the Company is the primary beneficiary of a VIE on an ongoing basis. Changes in facts and circumstances occurring since the previous primary beneficiary determination are considered as part of this ongoing assessment.
Alternative Energy Partnerships	Alternative Energy Partnerships: The Company invests in certain alternative energy partnerships formed to provide sustainable energy projects that are designed to generate a return primarily through the realization of federal tax credits (energy tax credits). The Company is a limited partner in these partnerships, which were formed to invest in newly installed residential rooftop solar leases and power purchase agreements. The investment is recorded using a Hypothetical Liquidation at Book Value (HLBV) method. The Company uses the flow-through income statement method to account for the tax credits earned on investments in alternative energy partnerships. Under this method, the tax credits are recognized as a reduction to income tax expense and the initial book-tax differences in the basis of the investments are recognized as additional tax expense in the year they are earned.
Stock Employee Compensation Trust	Stock Employee Compensation Trust: The Company maintains a Stock Employee Compensation Trust (SECT) to fund future employee stock compensation and benefit obligations of the Company. The SECT holds and will release shares of the Company's common stock to be used to fund the Company's obligations during the term of the SECT under certain stock and other employee benefit plans of the Company. The Company accounts for and presents the shares held by the SECT as treasury stock. As the Company allocates the shares to the designated plans, the shares are released from the SECT, and the Company recognizes compensation expenses based on the fair value of the shares on the grant date.
Earnings Per Common Share	arnings 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 Stock Appreciation Rights to the extent they confer dividend equivalent rights, as described under “Stock Appreciation Rights” in Note 14. Basic earnings per common share is computed by dividing net income allocated to common stockholders by the weighted average number of common shares outstanding, including the minimum number of shares issuable under purchase contracts relating to the tangible equity units, as described under "Tangible Equity Units" in Note 15. 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.
Accounting Pronouncements	Adopted Accounting Pronouncements: During the three months ended March 31, 2017 , the following pronouncement applicable to the Company was adopted: In March 2016, the FASB issued Accounting Standard Update (ASU) 2016-09, “ Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ” This Update was issued as a part of the FASB’s simplification initiative, and intends to improve the accounting for share-based payment transactions. The ASU changes several aspects of the accounting for share-based payment award transactions, including accounting for excess tax benefits and deficiencies, income statement recognition, cash flow classification, forfeitures, and tax withholding requirements. ASU 2016-09 is effective for public business entities in annual and interim periods in fiscal years beginning after December 15, 2016. Adoption of the new guidance did not have a significant impact on the Company's consolidated financial statements. See Note 11 for additional information. Recent Accounting Pronouncements Not Yet Adopted: The following are recently issued accounting pronouncements applicable to the Company that have not yet been adopted: In February 2016, the FASB issued ASU 2016-02, “ Leases (Topic 842) .” The amendments in this Update require lessees to recognize the assets and liabilities that arise from leases, as well as define classification criteria for distinguishing between financing leases and operating leases. This Update requires lessees to recognize all leases on the Consolidated Statement of Financial Condition as lease assets and lease liabilities based primarily on the present value of future lease payments. Lessor accounting is largely unchanged. A modified retrospective approach is required at adoption which requires all prior periods presented in the financial statements to be restated, with a cumulative effect adjustment to retained earnings as of the beginning of the earliest period presented. This guidance also requires additional disclosures regarding leasing arrangements. For public business entities, the amendments to this Update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption of the amendments in this Update is permitted. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In May 2016, the FASB issued ASU 2016-12, “ Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. ” This Update amends the guidance in ASU 2014-09, Revenue from Contracts with Customers , and clarifies the collectability criteria, accounting policy elections, noncash consideration, satisfied and unsatisfied performance obligations, completed contracts, and disclosures. The amendments in ASU 2016-12 affect the guidance in ASU 2014-09, which is effective for public business entities in annual and interim reporting periods beginning after December 15, 2017. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. As this ASU is not applicable to financial instruments, it will not impact the Company's major portion of revenue, net interest income, and the Company does not expect this guidance to have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, " Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. " The amendments in this Update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For public business entities that are SEC filers, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. The impact of this Update will depend upon the state of the economy and the nature of the Company's portfolio at the date of adoption. In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business.” The amendments in this Update provide a guidance on evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Currently, Topic 805 does not specify the minimum inputs and processes required for a set to meet the definition of a business. This Update presents a more robust framework to use when an entity determines whether a set of assets and activities represents a business. Also, this Update sets forth more consistency in applying the guidance with a more operable definition of a business. Public business entities must prospectively apply the amendments in this Update to annual periods beginning after December 15, 2017, including interim periods. The Company does not expect this guidance to have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” The amendments in this Update eliminate Step 2 from the goodwill impairment test when it is required. Instead, an entity must perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. For an impairment charge, an entity must recognize impairment by which the carrying amount exceeds the reporting unit’s fair value, but the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Furthermore, this Update requires an entity to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. Public business entities that are SEC filers must adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal year beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In February 2017, the FASB issued ASU 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets.” The amendments in this Update clarify the scope and application of ASC 610-20 on the sale or transfer of nonfinancial assets, including real estate, and in substance nonfinancial assets to noncustomers, including partial sales. An entity should identify each distinct nonfinancial asset or in substance nonfinancial asset promised to a counterparty and derecognize each asset when a counterparty obtains control of it. An in substance nonfinancial asset is an asset within a contract or subsidiary in which substantially all of the fair value of the asset is concentrated in a nonfinancial asset. In addition, the amendment requires an entity to derecognize a distinct nonfinancial asset or in substance nonfinancial asset in a partial sale transaction when the entity does not retain a controlling financial interest in the legal entity that holds the asset and an entity transfers control of the asset. Once control is transferred, any non-controlling interest received is required to be measured at fair value. The effective date of the new guidance is aligned with the requirements in the new revenue standard, which is effective for public business entities in annual and interim reporting periods beginning after December 15, 2017. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." The amendments in this Update shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount, which continue to be amortized to maturity. Public business entities must prospectively apply the amendments in this Update to annual periods beginning after December 15, 2018, including interim periods. The Company does not expect this guidance to have a material impact on its consolidated financial statements.
