Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations : Banc of California, Inc. is a financial holding company under the Bank Holding Company Act of 1956, as amended, headquartered in Orange County, California and incorporated under the laws of Maryland. Banc of California, Inc.'s assets primarily consist of the outstanding stock of the Bank. Banc of California, Inc. is subject to regulation by the Board of Governors of the Federal Reserve System and the Bank operates under a national bank charter issued by the OCC, its primary regulator. The Bank is a member of the FHLB system, and maintains insurance on deposit accounts with the FDIC. The Bank offers a variety of financial services to meet the banking and financial needs of the communities the Bank serves, with operations conducted through 39 banking offices, serving San Diego, Los Angeles, and Orange counties, California and 62 loan production offices in California, Arizona, Oregon, Virginia, Colorado, Idaho, North Carolina, and Nevada as of December 31, 2016 . Basis of Presentation: The consolidated financial statements include the accounts of the Company and all other entities in which it has a controlling financial interest. All significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiaries. The accounting and reporting polices of the Company are based upon GAAP and conform to predominant practices within the financial services industry. Significant accounting policies followed by the Company are presented below. Certain prior period amounts have been reclassified to conform to the current year's presentation. These reclassifications had no impact on the Company's consolidated financial condition, results of operations or net change in cash or cash equivalents. Use of Estimates in the Preparation of Financial Statements: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and disclosures provided, and actual results could differ. The allowance for loan and lease losses, reserve for loss on repurchased loans, servicing rights, realization of deferred tax assets, the valuation of goodwill and other intangible assets, mortgage banking derivatives, purchased credit impaired loan discount accretion, fair value of assets and liabilities acquired in business combinations, and the fair value measurement of financial instruments are particularly subject to change and such change could have a material effect on the consolidated financial statements. Cash and cash equivalents: Cash and cash equivalents include cash on hand, interest-bearing deposits with other financial institutions with original maturities under 90 days, and daily federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing deposits in other financial institutions, and federal funds purchased, including overnight borrowings with the FHLB. Cash flows from loans, either originated or acquired, are classified at that time according to management's original intent to either sell or hold the loan for the foreseeable future. When management's intent at origination or purchase is to sell the loan, the cash flows of that loan are presented as operating cash flows. When management's intent is to hold the loan for the foreseeable future, the cash flows of that loan are presented as investing cash flows. Time Deposits in Financial Institutions: Time deposits in financial institutions have original maturities over 90 days and are carried at cost. Investment Securities: Investment securities are classified at the time of purchase as available-for-sale or held-to-maturity. The Company presently has no investment securities classified as held-for-trading. Debt securities classified as held-to-maturity are recorded at amortized cost when management has the positive intent and ability to hold them to maturity. Debt securities are classified as available-for-sale when management intends that they might be sold before maturity. Equity securities with readily determinable fair values are classified as available-for-sale. Securities available-for-sale are carried at fair value with unrealized holding gains and losses. Unrealized holding gains and losses, net of taxes, are reported in AOCI on the Consolidated Statements of Financial Condition. Accreted discounts and amortized premiums are included in interest income using the level yield method, and realized gains or losses from sales of securities are calculated using the specific identification method. Management evaluates securities for OTTI at least on a quarterly basis, and more frequently when economic conditions warrant such an evaluation. Investment securities classified as available-for-sale or held-to-maturity are generally evaluated for OTTI under ASC 320, Accounting for Certain Investments in Debt and Equity Securities. However, certain purchased beneficial interests, including non-agency mortgage-backed securities, asset-backed securities, collateralized debt obligations, and collateralized loan obligations, that had credit ratings at the time of purchase of below AA are evaluated using the model outlined in ASC 325, Recognition of Interest Income and Impairment on Purchased Beneficial Interests and Beneficial Interests that Continue to be Held by a Transfer in Securitized Financial Assets. In determining OTTI under the ASC 320 model, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also considers whether the market decline was affected by macroeconomic conditions, and assesses whether the Company intends to sell, or it is more likely than not it will be required to sell a security in an unrealized loss position before recovery of its amortized cost basis. The assessment of whether OTTI exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. The second segment of the portfolio uses the OTTI guidance provided by ASC 325 that is specific to purchased beneficial interests that, on the purchase date, were rated below AA. Under the ASC 325 model, the Company compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows. When OTTI occurs in either model, the amount of the impairment recognized in earnings depends on the Company’s intent to sell the security or if it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (i) OTTI related to credit loss, which must be recognized in the income statement and (ii) other-than-temporary impairment related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities the entire amount of impairment is recognized through earnings. Federal Home Loan Bank and Federal Reserve Bank Stock: The Bank is a member of the FHLB and FRB system. Members are required to own a certain amount of FHLB and FRB stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB and FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported in Dividends and Other Interest-earning Assets Interest Income on the Consolidated Statements of Operations. Conforming SFR Mortgage Loans Held-for-Sale: Conforming SFR mortgage loans originated and intended for sale in the secondary market are carried at the fair value as of each balance sheet date, as determined by outstanding commitments from investors or what secondary markets are currently offering for portfolios with similar characteristics. The fair value includes the servicing value of the loans as well as any accrued interest. Conforming SFR mortgage loans held-for-sale are generally sold with servicing rights retained or sold through a flow agreement (See Note 7 for additional information). Origination fees and costs are recognized in earnings at the time of origination for newly originated loans held-for-sale. Gains and losses on sales of conforming SFR mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. The Company’s conforming SFR mortgage loans held-for-sale at fair value were GSE or Government-eligible at December 31, 2016 . These loans are considered to have reliable market price information and the fair value of these loans was based on quoted market prices of similar assets and included the value of loan servicing. In scenarios of market disruptions, the current secondary market prices that are generally relied on to value GSE or Government-eligible mortgage loans may not be readily available. In these circumstances, the Company may consider other factors, including: (i) quoted market prices for to-be-announced securities (for agency-eligible loans); (ii) recent transaction settlements or trades but unsettled transactions for similar assets; (iii) recent third party market transactions for similar assets; and (iv) modeled valuations using assumptions that the Bank believes would be used by market participants in estimating fair value (assumptions may include prepayment rates, interest rates, volatilities, mortgage spreads and projected loss rates). Adjustments to reflect unrealized gains and losses resulting from changes in fair value and realized gains and losses upon ultimate sale of the loans are classified as part of Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations. Non-Conforming SFR Mortgage Loans Held-for-Sale: Non-conforming SFR mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value on an aggregate basis. A decline in the aggregate fair value of the loans below their aggregate carrying amount is recognized through a charge to earnings in the period of such a decline. Unearned income on the loans is taken into earnings when they are sold. Gains and losses on sales of non-conforming SFR mortgage loans are included in Net Gain on Sale of Loans on the Consolidated Statements of Operations. SBA Loans Held-for-Sale: SBA loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated market value in the aggregate. Net unrealized losses are recognized through a valuation allowance by charges to income. Gains or losses realized on the sales of SBA loans are recognized at the time of sale and are determined by the difference between the net sales proceeds and the carrying value of the loans sold, adjusted for any servicing asset or liability. Gains and losses on sales of SBA loans are included in Net Gain on Sale of Loans on the Consolidated Statements of Operations. Loans and Leases: Loans and leases, other than PCI loans, that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff are recorded at the principal balance outstanding, net of charge-offs, unamortized purchase premiums and discounts, and deferred loan fees and costs. The deferred loan fees and costs, and purchase premiums and discounts are recognized in interest income as an adjustment to yield over the term of loans and leases using the effective interest method. Interest on loans and leases is credited to interest income as earned based on the interest rate applied to principal amounts outstanding. Interest income is accrued on the unpaid principal balance and is discontinued when management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that full collection of principal or interest becomes doubtful, regardless of the length of past due status. Generally loans and leases are placed on nonaccrual status when their payments are past due for 90 days or more. When interest accrual is discontinued, all unpaid accrued interest is reversed against interest income. Interest received on such loans and leases is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. A charge-off is generally recorded at 180 days past due if the unpaid principal balance exceeds the fair value of the collateral less costs to sell. Commercial and industrial and commercial real estate loans and equipment finance leases are subject to a detailed review when 90 days past due to determine accrual status, or when payment is uncertain and a specific consideration is made to put a loan or lease on non-accrual status. Consumer loans, other than those secured by real estate, are typically charged off no later than 180 days past due. Loans and leases are returned to accrual status when the borrower has demonstrated a satisfactory payment trend subject to management’s assessment of the borrower’s ability to repay the loan or lease. Allowance for Loan and Lease Losses: The ALLL is a reserve established through a provision for loan and lease loses charged to expense, and represents management’s best estimate of probable losses that may be incurred within the existing loan and lease portfolio as of the date of the consolidated financial statements. Subsequent recoveries, if any, are credited to the ALLL. The Company performs an analysis of the adequacy of the ALLL at least on a quarterly basis. Management estimates the ALLL balance required using past loan and lease loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. The ALLL consists of three elements; (i) specific valuation allowances established for probable losses on impaired loans and leases, (ii) quantitative valuation allowances calculated using loss experience for loans and leases with similar characteristics and trends, adjusted as necessary to reflect the impact of current conditions; and (iii) qualitative allowances determined based on environmental and other factors that may be internal or external to the Company. A loan or lease is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan or lease agreement. The Company evaluates all impaired loans and leases individually under the guidance of ASC 310, Receivables, primarily through the evaluation of collateral values and estimated cash flows. Loans for which the terms have been modified by granting a concession that normally would not be provided and where the borrower is experiencing financial difficulties are considered TDRs and classified as impaired. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The impairment amount on a collateral dependent loan is charged-off to the ALLL and the impairment amount on a loan that is not collateral dependent is set-up as a specific reserve. TDRs are also measured at the present value of estimated future cash flows using the loan’s effective rate at inception or at the fair value of collateral, less costs to sell, if repayment is expected solely from the collateral. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the ALLL. At December 31, 2016 , the following loan and lease portfolio segments have been identified: • Commercial and industrial (secured, unsecured, securities-backed lines of credit, warehouse lending, and leveraged lending) • Commercial real estate (retail, office, industrial, hospitality, and other) • Multi-family • SBA • Construction • Leases • SFR - 1st deeds of trust (amortizing, interest only now amortizing, interest only, negative amortizing, and Green Loans) • Other consumer (SFR, including HELOC - 2nd deeds of trust and other) The Company categorizes loans and leases into risk categories based on relevant information about the ability of borrowers and lessees (also referred to as borrowers) to service their obligations such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. 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. Classification of problem SFR mortgage loans is performed on a monthly basis while analysis of non-homogeneous loans is performed on a quarterly basis. Loans secured by multi-family and commercial real estate properties generally involve a greater degree of credit risk than SFR mortgage loans. Because payments on loans secured by multi-family and commercial real estate properties are often dependent on the successful operation or management of the properties, repayment of these loans may be subject to adverse conditions in the real estate market or the economy. Commercial business loans are also considered to have a greater degree of credit risk than SFR mortgage loans due to the fact commercial business loans are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment of commercial business loans may be substantially dependent on the success of the business itself (which, in turn, is often dependent in part upon general economic conditions). SBA loans are similar to commercial business loans, but have additional credit enhancement provided by the U.S. Small Business Administration, for up to 85 percent of the loan amount for loans up to $150 thousand and 75 percent of the loan amount for loans of more than $150 thousand. Commercial equipment leases are also similar to commercial business loans in that the leases are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment of commercial equipment leases may be substantially dependent on the success of the business itself (which, in turn, is often dependent in part upon general economic conditions). Consumer and other real estate loans may entail greater risk than do SFR mortgage loans given that collection of these loans is dependent on the borrower’s continuing financial stability and, thus, are more likely to be adversely affected by job loss, divorce, illness, or personal bankruptcy. Green Loans are also considered to carry a higher degree of credit risk due to their unique cash flows. Credit risk on this asset class is also managed through the completion of regular re-appraisals of the underlying collateral and monitoring of the borrower’s usage of this account to determine if the borrower is making monthly payments from external sources or “drawdowns” on their line. In cases where the property values have declined to levels less than the original LTV ratios, or other levels deemed prudent by the Company, the Company may curtail the line and/or require monthly payments or principal reductions to bring the loan in balance. Classified Assets: Federal regulations provide for the classification of loans, leases, and other assets, such as debt and equity securities considered to be of lesser quality, as “substandard,” “doubtful” or “loss.” An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. “Substandard” assets include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses inherent in those classified “substandard,” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions, and values, “highly questionable and improbable.” Assets classified as “loss” are those considered “uncollectible” and of such little value that their continuance as assets without the establishment of a specific loss reserve is not warranted. When an insured institution classifies problem assets as “loss,” it is required to charge off such amount. The Bank’s determination as to the classification of its assets and the amount of its valuation allowances is subject to review by its primary regulator, which may order the establishment of additional general or specific loss allowances. Troubled Debt Restructurings: A loan is identified as a TDR when a borrower is experiencing financial difficulties and for economic or legal reasons related to these difficulties, the Company grants a concession to the borrower in the restructuring that it would not otherwise consider. The Company has granted a concession when, as a result of the restructuring to a troubled borrower, it does not expect to collect all amounts due, including principal and/or interest accrued at the original terms of the loan. The concessions may be granted in various forms, including a below-market change in the stated interest rate, a reduction in the loan balance or accrued interest, an extension of the maturity date, or a note split with principal forgiveness. Loans for which the borrower has been discharged under Chapter 7 bankruptcy are considered collateral dependent TDRs, impaired at the date of discharge, and charged down to the fair value of collateral less cost to sell. A restructuring executed at an interest rate that is at market interest rates based on the current credit characteristics of the borrower is not a TDR. The Company’s policy is to place consumer loan TDRs, except those that were performing prior to TDR status, on non-accrual status for a minimum period of 6 months . Commercial TDRs are evaluated on a case-by-case basis for determination of whether or not to place on non-accrual status. Loans qualify for return to accrual status once they have demonstrated performance with the restructured terms of the loan agreement for a minimum of 6 months. Initially, all TDRs are reported as impaired. Generally, TDRs are classified as impaired loans and reported as TDRs for the remaining life of the loan. Impaired and TDR classification may be removed if the borrower demonstrates compliance with the modified terms for a minimum of 6 months and through one fiscal year-end and the restructuring agreement specifies a market rate of interest equal to that which would be provided to a borrower with similar credit at the time of restructuring. In the limited circumstance that a loan is removed from TDR classification, it is the Company’s policy to continue to base its measure of loan impairment on the contractual terms specified by the loan agreement. Purchased Credit-Impaired Loans: The Company purchases loans with and without evidence of credit quality deterioration since origination. Evidence of credit quality deterioration as of the purchase date may include statistics such as prior loan modification history, updated borrower credit scores and updated LTV ratios, some of which may not be immediately available as of the purchase date. Purchased loans with evidence of credit quality deterioration where the Company estimates that it will not receive all contractual payments are accounted for as PCI loans. The excess of the cash flows expected to be collected on PCI loans, measured as of the acquisition date, over the estimated fair value is referred to as the accretable yield and is recognized in interest income over the remaining life of the loan or lease using a level yield methodology. The difference between contractually required payments as of the acquisition date and the cash flows expected to be collected is referred to as the non-accretable difference. PCI loans that have similar risk characteristics, primarily credit risk, collateral type and interest rate risk, are pooled and accounted for as a single unit with a single composite interest rate and an aggregate expectation of cash flows. Loans that were acquired during the year ended December 31, 2012 in connection with the Beach Business Bank and Gateway Bancorp acquisitions and during the year ended December 31, 2013 in connection with the The Private Bank of California acquisition that were considered credit impaired were recorded at fair value at the acquisition date and the related ALLL was not carried over to the Company’s ALLL. In addition, the Company acquired one PCI seasoned SFR mortgage loan pool during the year ended December 31, 2016, seven pools of seasoned SFR mortgage loans, which were partially PCI loans, during the year ended December 31, 2015, five pools of seasoned SFR mortgage loans, which were partially PCI loans, during the year ended December 31, 2013, and three pools of PCI seasoned SFR mortgage loans during the year ended December 31, 2012. Any losses on such loans are charged against the non-accretable difference established in purchase accounting and are not reported as charge-offs until such non-accretable difference is fully utilized. These loans were evaluated individually and were not part of the aforementioned pools. The Company estimates cash flows expected to be collected over the life of the loan using management’s best estimate which is derived using current key assumptions such as default rates, loss severity and payment speeds. If, upon subsequent evaluation, the Company determines it is probable that the present value of the expected cash flows have decreased due to a deterioration of credit, the PCI loan is considered further impaired which will result in a charge to the provision for loan and lease losses and a corresponding increase to the ALLL. If, upon subsequent evaluation, it is probable that there is an increase in the present value of the expected cash flows, the Company will reduce any remaining allowance. If there is no remaining allowance, the Company will recalculate the amount of accretable yield as the excess of the revised expected cash flows over the current carrying value resulting in a reclassification from non-accretable difference to accretable yield. The present value of the expected cash flows for PCI purchased loan pools is determined using the PCI loans’ effective interest rate, adjusted for changes in the PCI loans’ interest rate indexes. Adjustments in interest rate assumptions and prepayment behavior do not impact the Company’s assessment of credit impairment. The present value of the expected cash flows for PCI loans acquired through mergers with other banks includes, in addition to the above, an evaluation of the creditworthiness of the borrower. Loan dispositions may include sales of loans, receipt of payments in full from the borrower or foreclosure. Write-downs are not recorded on the PCI loan pool until actual losses exceed the remaining non-accretable difference. To date, no write-downs have been recorded for the PCI loans held by the Company. Other Real Estate Owned: OREO, which represents real estate acquired through foreclosure in satisfaction of commercial and real estate loans, is initially recorded at fair value less estimated selling costs of the real estate, based on current independent appraisals obtained at the time of acquisition, less costs to sell when acquired, establishing a new cost basis. Loan balances in excess of fair value of the real estate acquired at the date of acquisition are charged to the ALLL. Gains and losses on the sale of OREO are included in Net Gain on Sales of Other Real Estate Owned, reductions in fair value subsequent to foreclosure are included in Valuation Allowance for Other Real Estate Owned and any subsequent operating expenses or income of such properties are included in All Other Expense on the Consolidated Statements of Operations. Premises, Equipment, and Capital Leases: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method with the following estimated useful lives: building - 40 years and leasehold improvements - life of lease, and furniture, fixtures, and equipment - 3 to 7 years . Maintenance and repairs are charged to expense as incurred, and improvements that extend the useful lives of assets are capitalized. Bank Owned Life Insurance: The Bank has purchased life insurance policies on certain key current and former executives. BOLI is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Servicing Rights - Mortgage (Carried at Fair Value): A servicing asset or liability is recognized when undertaking an obligation to service a financial asset under a mortgage servicing contract, including a transfer of the servicer’s financial assets that meet the requirements for sale accounting. Such servicing asset or liability is initially measured at fair value based on either market prices for comparable servicing contracts or alternatively is based on a valuation model that is based on the present value of the contractually specified servicing fee, net of servicing costs, over the estimated life of the loan, using a discount rate based on the related note rate and is recorded on the Consolidated Statements of Operations. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. Under the fair value measurement method, the Company measures servicing rights at fair value at each reporting date and reports changes in fair value of servicing assets in earnings in the period in which the changes occur, and are included with Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimates and actual prepayment speeds and default rates and losses. Currently the Company does not hedge the income statement effects of changes in fair value of the servicing assets. Servicing fee income, which is reported in Loan Servicing Income on the Consolidated Statements of Operations, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal; or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees related to loan servicing are not material. Servicing Rights - SBA Loans (Carried at Lower of Cost or Fair Value): As a general course of business, the Bank originates and sells the guaranteed portion of its SBA loans. To calculate the gain (loss) on sales of SBA loans, the Bank’s investment in the loan is allocated among the retained portion of the loan, the servicing retained, the interest-only strip and the sold portion of the loan, based on the relative fai

The following table summarizes the total consideration transferred as a part of the BPNA Branch Acquisition as well as the fair value adjustments to the BPNA balance sheet as of the respective acquisition date: November 8, 2014 (In thousands) Total Consideration $ 27,941 Net assets pre-acquisition 24,027 Fair value adjustments Loans receivable $ (19,526 ) Core Deposit Intangibles 15,777 Certificates of deposit purchase premium (1,208 ) Premises and equipment 1,218 Total fair value adjustments (3,739 ) Fair value of net assets acquired 20,288 Consideration paid in excess of fair value of net assets acquired (goodwill) $ 7,653 The Company recorded core deposit intangible assets of $15.8 million as part of the BPNA Branch Acquisition. Core deposit intangible assets were valued using a net cost savings method and was calculated as the present value of the estimated net cost savings attributable to the core deposit base over the expected remaining life of the deposits. The cost savings derived from the core deposit balance were calculated as the difference between the prevailing alternative cost of funds and the estimated cost of the core deposits. The core deposit intangible is being amortized over its estimated useful life of ten years using the sum of years-digits amortization methodology. The fair value of loans acquired from BPNA was estimated by utilizing a methodology wherein similar loans were aggregated into pools. Cash flows for each pool were determined by estimating future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value based on a market rate for similar loans. There was no carryover of BPNA's allowance for loan losses associated with the acquired loans as the loans were initially recorded at fair value. The fair value of savings and transaction deposit accounts acquired from BPNA was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. Certificates of deposit were valued by projecting the expected cash flows based on the remaining contractual terms of the certificates of deposit. These cash flows were discounted based on market rates for certificates of deposit with corresponding remaining maturities. Direct costs related to the BPNA Branch Acquisition were expensed as incurred and amounted to $4.3 million for the year ended December 31, 2014. During the year ended December 31, 2015, the Company finalized its purchase accounting for the BPNA Branch Acquisition and recorded the measurement period adjustments. The measurement period adjustments included recording Goodwill of $7.7 million , an additional discount of $7.4 million to Loans and Leases Receivable, and an additional premium of $292 thousand to Deposits. Recorded in the Consolidated Statements of Operations, the cumulative life to date measurement period adjustments related to the loan discount and deposit premium amortization were a $33 thousand decrease in Interest and Dividend Income on Loans and a $110 thousand decrease in Interest Expense on Deposits, respectively. RenovationReady® Acquisition Effective January 31, 2014, the Company acquired certain assets, including service contracts and intellectual property, of RenovationReady, a provider of specialized loan services to financial institutions and mortgage bankers that originate agency eligible residential renovation and construction loan products. The RenovationReady acquisition was accounted for under GAAP guidance for business combinations. The purchased identifiable intangible assets and assumed liabilities were recorded at their estimated fair values as of January 31, 2014. The Company recorded $2.2 million of goodwill and $761 thousand of other intangible assets. The other intangible assets are related to a customer relationship intangible. Building Sale On June 25, 2015, the Company sold an improved real property office complex located at 1588 South Coast Drive, Costa Mesa, California (the Property) at a sale price of approximately $52.3 million with a gain on sale of $9.9 million . The Property had a book value of $42.3 million at the sale date. Additionally, the Company incurred selling costs of $2.3 million for this transaction, which were reported in Professional Fees and All Other Expenses in the Consolidated Statements of Operations for the year ended December 31, 2015. Branch Sale On September 25, 2015, the Company completed a branch sale transaction to Americas United Bank, a California banking corporation (AUB). In the transaction, the Company sold two branches and certain related assets and deposit liabilities to AUB. The transaction included a transfer of $46.9 million of deposits to AUB. Additionally, as part of the transaction, the leases related to both locations were assumed by AUB. The Company recognized a gain of $163 thousand from this transaction, which is included in Other Income in the Consolidated Statements of Operations for the year ended December 31, 2015. The Company also sold certain loans of $40.2 million to AUB as part of the transaction. The Company recognized a gain of $644 thousand from the sale of these loans, which is included in Net Gain on Sale of Loans in the Consolidated Statements of Operations. 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 who serve as the 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. The following table summarizes the calculation of the gain on sale of The Palisades Group recognized: Year Ended (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 subsequently paid in full in cash prior to maturity and the Company recognized an additional gain of $2.8 million , which is included in Other Income in the Consolidated Statements of Operations. 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).

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 SBA loan pool securities, 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 December 31, 2016 and 2015 . 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. Interest Rate Swaps and Caps . The Company has entered into pay-fixed, receive-variable interest rate swap contracts with institutional counterparties to hedge against variability in cash flows attributable to interest rate risk caused by changes in the LIBOR benchmark interest rate on the Company’s ongoing LIBOR-based variable rate deposits and other borrowings. The Company also 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 and elected the fair value option for valuation of these mortgage servicing rights (MSRs). The value is based on a third party provider that calculates the present value of the expected net servicing income from the portfolio based on key factors that include interest rates, prepayment assumptions, discount rate and estimated cash flows. Because of the significance of unobservable inputs, these servicing rights are classified as Level 3. The following table presents the Company’s financial assets and liabilities measured at fair value on a recurring basis as of the dates indicated: Fair Value Measurement Level Carrying Value Quoted Prices Significant Significant (In thousands) December 31, 2016 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 obligations 1,406,869 — 1,406,869 — Commercial mortgage-backed securities — — Agency mortgage-backed securities 807,273 — 807,273 — Loans held-for-sale, carried at fair value 416,974 — 358,714 58,260 Derivative assets (1) 17,968 — 17,968 — Mortgage servicing rights (2) 76,121 — — 76,121 Liabilities Derivative liabilities (3) 2,116 — 2,116 — December 31, 2015 Assets Securities available-for-sale: SBA loan pools securities $ 1,504 $ — $ 1,504 $ — Private label residential mortgage-backed securities 1,768 — 1,768 — Corporate bonds 26,152 — 26,152 — Collateralized loan obligations 111,468 — 111,468 — Agency mortgage-backed securities 692,704 — 692,704 — Loans held-for-sale, carried at fair value 379,155 — 360,864 18,291 Derivative assets (1) 9,042 — 9,042 — Mortgage servicing rights (2) 49,939 — — 49,939 Liabilities Derivative liabilities (3) 1,067 — 1,067 — (1) Included in Other Assets in the Consolidated Statements of Financial Condition (2) Included in Servicing Rights, Net in the Consolidated Statements of Financial Condition (3) Included in Accrued Expenses and Other Liabilities in the Consolidated Statements of Financial Condition The following table presents a reconciliation of assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the periods indicated: Mortgage Servicing Rights Loans Repurchased from Ginnie Mae Loan Pools Total (In thousands) Balance at December 31, 2013 $ 13,535 $ — $ 13,535 Transfers in (out of) Level 3 (1) — — — Total gains or losses (realized/unrealized): Included in earnings-fair value adjustment (233 ) — (233 ) Additions 26,399 — 26,399 Sales and settlements (20,619 ) — (20,619 ) Balance at December 31, 2014 $ 19,082 $ — $ 19,082 Transfers in (out of) Level 3 (1) $ — $ 1,088 $ 1,088 Total gains or losses (realized/unrealized): Included in earnings-fair value adjustment (3,568 ) — (3,568 ) Additions 45,263 18,555 63,818 Sales and settlements (10,838 ) (1,352 ) (12,190 ) Balance at December 31, 2015 $ 49,939 $ 18,291 $ 68,230 Transfers in (out of) Level 3 (1) $ — $ — $ — Total gains or losses (realized/unrealized): Included in earnings-fair value adjustment (5,709 ) 216 (5,493 ) Additions 49,293 51,123 100,416 Sales and settlements (17,402 ) (11,370 ) (28,772 ) Balance at December 31, 2016 $ 76,121 $ 58,260 $ 134,381 (1) The Company’s policy is to recognize transfers in and transfers out as of the actual date of the event or change in circumstances that causes the transfer. Loans repurchased from Ginnie Mae Loan pools had aggregated unpaid principal balances of $58.3 million and $18.6 million at December 31, 2016 and 2015, respectively. 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 December 31, 2016 and 2015: Fair Value (In thousands) Valuation Technique(s) Unobservable Input(s) Range (Weighted Average) December 31, 2016 Mortgage servicing rights $ 76,121 Discounted cash flow Discount rate 9.11% to 15.00% (10.18%) Prepayment rate 7.00% to 39.90% (11.84%) December 31, 2015 Mortgage servicing rights $ 49,939 Discounted cash flow Discount rate 9.00% to 18.00% (9.75%) Prepayment rate 6.07% to 35.01% (11.81%) 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 included an expected loss rate of 1.55 percent and 1.85 percent at December 31, 2016 and 2015, respectively. 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 under the fair value option: December 31, 2016 2015 Fair Value Unpaid Principal Balance Difference Fair Value Unpaid Principal Balance Difference (In thousands) Loans held-for-sale, carried at fair value: Total loans $ 416,974 $ 407,889 $ 9,085 $ 379,155 $ 368,039 $ 11,116 Nonaccrual loans 54,151 54,824 (673 ) 19,576 19,955 (379 ) 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: Year Ended December 31, 2016 2015 2014 (In thousands) Net revenue on mortgage banking activities: Net gains from fair value changes $ 7,365 $ 11,326 $ 10,875 Changes in fair value due to instrument-specific credit risk were insignificant for the years ended December 31, 2016, 2015 and 2014. 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 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 OTTI are considered to be carried at fair value. The Company did not have any OTTI on securities held-to-maturity at December 31, 2016 or 2015. 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 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: 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 $31 thousand , $38 thousand and $32 thousand , respectively, for the years ended December 31, 2016 , 2015 , and 2014 in All Other Expense in the Consolidated Statements of Operations. Alternative Investments (Affordable Housing Fund Investment, SBIC, and Other Investment): The Company generally accounts for its percentage ownership of alternative investment funds at cost, subject to impairment testing. These are non-public investments that cannot be redeemed since the Company’s investment is distributed as the underlying investments are liquidated, which generally takes 10 years. There are currently no plans to sell any of these investments prior to their liquidation. The Company also invests in certain alternative energy partnerships formed to provide sustainable energy projects that are accounted for under the equity method. The alternative investments carried at cost are considered to be measured at fair value on a non-recurring basis when there is impairment. The Company had unfunded commitments of $335 thousand , $12.2 million , and $42.7 million for Affordable House Fund Investment, SBIC, and Other Investments, including investments in alternative energy partnerships, at December 31, 2016 , respectively. The Company recorded no impairment on these investments.

Federal Home Loan Bank and Other Bank Stock: FHLB and other bank stock is recorded at cost. Ownership of FHLB stock is restricted to member banks, and purchases and sales of these securities are at par value with the issuer (Level 2). Securities Held-to-Maturity: 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 Allowance for Loan and Lease Losses: The fair value of loans and leases receivable is estimated based on the discounted cash flow approach. The discount rate was derived from the associated yield curve plus spreads and reflects the rates offered by the Bank for loans with similar financial characteristics. Yield curves are constructed by product and payment types. These rates could be different from what other financial institutions could offer for these loans. Additionally, the fair value of our loans may differ significantly from the values that would have been used had a ready market existed for such loans and may differ materially from the values that we may ultimately realize (Level 3). Accrued Interest Receivable: The carrying amount of accrued interest receivable approximates its fair value (Level 1). Deposits: The fair value of deposits is estimated based on discounted cash flows. The cash flows for non-maturity deposits, including savings accounts and money market checking, are estimated based on their historical decaying experiences. The discount rate used for fair valuation is based on interest rates currently being offered by the Bank on comparable deposits as to amount and term (Level 3). Advances from Federal Home Loan Bank: The fair values of advances from FHLB are estimated based on the discounted cash flows approach. The discount rate was derived from the current market rates for borrowings with similar remaining maturities (Level 2). Long Term Debt: Fair value of long term debt is determined by observable data such as market spreads, cash flows, yield curves, credit information, and respective terms and conditions for debt instruments (Level 2). Accrued Interest Payable: The carrying amount of accrued interest payable approximates its fair value (Level 1).

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

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. Overall improvement on both held-to-maturity and available-for-sale portfolios at December 31, 2016 were mainly due to tighter credit spreads at December 31, 2016 and improvement in the economic sectors for the bond issuers. The unrealized losses were attributable to higher market interest rates at December 31, 2016 which negatively impacted the fair value of fixed rate agency mortgage backed securities. The Company monitors its securities portfolio to ensure it has adequate credit support. As of December 31, 2016 , the Company believes there is no OTTI and did not have the intent to sell these securities and it is not likely that it will be required to sell the securities before their anticipated recovery. The Company considers the lowest credit rating for identification of potential OTTI. As of December 31, 2016 , all of the Company's investment securities in an unrealized loss position received an investment grade credit rating.

As of December 31, 2016 and 2015 , the NTM loans totaled $885.1 million , or 14.7 percent of total loans and leases, and $785.9 million , or 15.2 percent of total loans and leases, respectively. The total NTM portfolio increased by $99.2 million , or 12.6 percent , during the year ended December 31, 2016 . The following table presents the composition of the NTM portfolio as of the dates indicated: December 31, 2016 2015 Count Amount Percent Count Amount Percent ($ in thousands) Green Loans (HELOC) - first liens 107 $ 87,469 9.9 % 121 $ 105,131 13.4 % Interest only - first liens 522 784,364 88.6 % 521 664,358 84.4 % Negative amortization 22 9,756 1.1 % 30 11,602 1.5 % Total NTM - first liens 651 881,589 99.6 % 672 781,091 99.3 % Green Loans (HELOC) - second liens 12 3,559 0.4 % 16 4,704 0.6 % Interest only - second liens — — — % 1 113 0.1 % Total NTM - second liens 12 3,559 0.4 % 17 4,817 0.7 % Total NTM loans 663 885,148 100.0 % 689 785,908 100.0 % Total loans and leases $ 6,034,752 $ 5,184,394 Percentage to total loans and leases 14.7 % 15.2 % Green Loans Green Loans are single family residential 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 December 31, 2016 and 2015 , Green Loans totaled $91.0 million and $109.8 million , respectively. At December 31, 2016 and 2015 , $0 and $10.1 million , respectively, of the Company’s Green Loans were non-performing. As a result of their unique payment feature, Green Loans possess higher credit risk due to the potential for negative amortization; however, management believes the risk is mitigated through the Company’s loan terms and underwriting standards, including its policies on 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 single family residential first mortgage loans with payment features that allow interest only payments in initial periods before converting to a fully amortizing loan. At December 31, 2016 and 2015 , interest only loans totaled $784.4 million and $664.5 million , respectively. At December 31, 2016 and 2015 , $467 thousand and $4.6 million of the interest only loans were non-performing, respectively. Loans with the Potential for Negative Amortization Negative amortization loans totaled $9.8 million and $11.6 million at December 31, 2016 and 2015 , respectively. The Company discontinued origination of negative amortization loans in 2007. At December 31, 2016 and 2015 , no ne 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 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 HELOCs, as needed in conjunction with portfolio management, and ordering third party 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 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. Non-Traditional Mortgage Performance Indicators The following table presents the Company’s NTM Green Loans first lien portfolio at December 31, 2016 by FICO scores that were obtained during the quarter ended December 31, 2016 , comparing to the FICO scores for those same loans that were obtained during the quarter ended December 31, 2015 : December 31, 2016 By FICO Scores Obtained During the Quarter Ended December 31, 2016 By FICO Scores Obtained Change Count Amount Percent Count Amount Percent Count Amount Percent ($ in thousands) FICO Score 800+ 16 $ 9,586 11.0 % 20 $ 13,831 15.8 % (4 ) $ (4,245 ) (4.8 )% 700-799 55 43,337 49.5 % 55 44,310 50.7 % — (973 ) (1.2 )% 600-699 28 27,327 31.2 % 21 21,039 24.1 % 7 6,288 7.1 % <600 1 1,800 2.1 % 3 2,573 2.9 % (2 ) (773 ) (0.8 )% No FICO score 7 5,419 6.2 % 8 5,716 6.5 % (1 ) (297 ) (0.3 )% Totals 107 $ 87,469 100.0 % 107 $ 87,469 100.0 % — $ — — % 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.

Allowance for Loan and Lease Losses The Company has an established credit risk management process that includes regular management review of the loan and lease portfolio to identify problem loans and leases. During the ordinary course of business, management becomes aware of borrowers and lessees that may not be able to meet the contractual requirements of the loan and lease agreements. Such loans and leases are subject to increased monitoring. Consideration is given to placing the loan or lease on non-accrual status, assessing the need for additional 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 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 December 31, 2016 and 2015 , the reserve for unfunded loan commitments was $2.4 million and $2.1 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 provides oversight and guidance for management’s allowance evaluation process, including quarterly valuations, and consideration of management’s determination of whether the allowance is appropriate to absorb losses in the loan and lease portfolio. 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.

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.

Credit Quality Indicators The Company categorizes loans and leases into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company performs historical loss analysis that is combined with a comprehensive loan or lease to value analysis to analyze the associated risks in the current loan and lease portfolio. The Company analyzes loans and leases individually by classifying the loans and leases as to credit risk. This analysis includes all loans and leases delinquent over 60 days and non-homogeneous loans and leases such as commercial and commercial real estate loans and leases. Classification of problem single family residential loans is performed on a monthly basis while analysis of non-homogeneous loans and leases is performed on a quarterly basis. The Company uses the following definitions for risk ratings: Pass : Loans and leases classified as pass are in compliance in all respects with the Bank’s credit policy and regulatory requirements, and do not exhibit any potential or defined weakness as defined under “Special Mention”, “Substandard” or “Doubtful.” 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.

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. Income from servicing rights was $5.4 million , $3.0 million and $4.2 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively. The Company recognized losses on the fair value and runoff of servicing rights of $17.7 million , $8.8 million and $1.6 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively. These losses were partially offset by increases in servicing fees. The Company recognized servicing fees of $23.1 million , $11.7 million , and $5.8 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively. The decrease in fair value of servicing rights was due to increases in prepayment speeds, higher yield, and shorter weighted average life, and the increase in servicing fees was due to the increase in unpaid principal balance of loans sold with servicing retained. These amounts are reported in Loan Servicing Income 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 future residential mortgage loan sales to GSEs. The flow agreement will allow 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 is expected to reduce 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. The Company sold MSRs of $5.4 million , representing $525.6 million of total principal balance, through the flow agreement during the year ended December 31, 2016 . On February 1, 2017, the Company and the third party MSR investor agreed to suspend MSR flow sales due to Company announcements concerning the Special Committee investigation and management changes at the Company. The Company is currently exploring options for selling MSRs contemporaneously with the sale of SFR mortgage loans to the GSEs as well as the Company’s existing MSRs.

At December 31, 2016 , the Company had $3.3 million of available unused federal net operating loss (NOL) carryforwards that may be applied against future taxable income through 2031 . The Company had available at December 31, 2016 , $12.2 million of unused state NOL carryforwards that may be applied against future taxable income through 2031 . Utilization of the NOL and other carryforwards are subject to annual limitations set forth in Section 382 of the Internal Revenue Code (IRC). The tax attributes acquired in the Beach Business Bank and Gateway Bancorp acquisitions are subject to an annual IRC Section 382 limitation of $1.3 million and $474 thousand , respectively. Additionally, the Company's tax attributes are limited to an annual IRC Section 382 limitation of $9.8 million . The following table presents the tax effects of temporary differences that give rise to significant portions of deferred tax assets and deferred tax liabilities as of the dates indicated: December 31, 2016 2015 (In thousands) Deferred tax assets: Allowance for loan and lease losses $ 18,921 $ 20,684 Stock options and awards 6,118 4,660 Accrued expenses 10,209 2,090 Valuation allowance on other real estate owned 3 29 Reserve for loss on repurchased loans 3,426 4,028 Federal net operating losses 1,162 1,328 State net operating losses 810 869 Federal credits — 10 Unrealized loss on securities available-for-sale 6,438 2,177 Other deferred tax assets 6,409 10,690 Total deferred tax assets 53,496 46,565 Deferred tax liabilities: Derivative instruments adjustment (6,559 ) (3,409 ) Investment in partnership (1,945 ) — Mortgage servicing rights (31,658 ) (20,735 ) FHLB stock dividends (314 ) (564 ) Intangible amortization (30 ) (857 ) Other deferred tax liabilities (3,001 ) (9,659 ) Total deferred tax liabilities (43,507 ) (35,224 ) Valuation allowance — — Net deferred tax assets $ 9,989 $ 11,341 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, 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, the Company recorded no valuation allowance against net deferred tax assets of $10.0 million and $11.3 million at December 31, 2016 and 2015 , respectively. During the year ended December 31, 2016 , estimated taxable income before utilization of NOLs of $131.1 million allowed the Company to utilize $474 thousand and $1.9 million of federal and state NOL (representing approximately 13.8 percent of the total NOLs included in the Company’s deferred tax assets), $209 thousand of research tax credits, and all of its $435 thousand of federal low income housing tax credits. The remaining NOLs are limited under IRC Section 382 and will expire if not used by 2031. In order to utilize all of its existing NOL carryover, the Company would only need taxable income of approximately $1.8 million and $1.4 million in 2017 and 2018, respectively, and approximately $474 thousand in each year from 2019 to 2031. The Company believes that the utilization of a significant portion of the NOL and tax credits in 2016, along with the Company’s projection of future taxable income should be considered significant positive evidence that the NOL deferred tax assets will be realized in future periods. Taking all of the foregoing information into account, management believes that it is “more likely than not” that all of the Company’s federal and state net deferred assets will be realized in future years and that, as of December 31, 2016 , no valuation allowance against its federal and state deferred tax assets is required. ASC 740-10-25 relates to the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. ASC 740-10-25 prescribes a threshold and a measurement process for recognizing in the financial statements a tax position taken or expected to be taken in a tax return and also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company had unrecognized tax benefits of $0 at December 31, 2016 and 2015 . The Company has changed its tax accounting method for various items and filed amended state income tax returns to reflect audit adjustments during the year ended December 31, 2015. As a result, the total amount of unrecognized tax benefits has decreased by $5.4 million during the year ended December 31, 2015. The Company does not believe that the unrecognized tax benefits will change within the next twelve months. As of December 31, 2016 , the total unrecognized tax benefit that, if recognized, would impact the effective tax rate was $0 . At December 31, 2016 and 2015 , the Company had no accrued interest or penalties, respectively. The table below summaries the activity related to our unrecognized tax benefits: Year Ended December 31, 2016 2015 2014 (In thousands) Beginning balance $ — $ 5,421 $ 2,203 (Decrease) increase related to prior year tax positions — (5,421 ) 369 Increase in current year tax positions — — 2,849 Ending balance $ — $ — $ 5,421 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 is no longer subject to examination by U.S. federal taxing authorities 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 accounts for Qualified Affordable Housing Investments under the proportional amortization method. The gross investments in these limited partnerships amounted to $29.1 million and the unfunded portion was $335 thousand at December 31, 2016. The balances of these investments were $23.2 million and $3.6 million as of December 31, 2016 and 2015, respectively. The Company utilized $225 thousand of tax deductions and $435 thousand of tax credits generated in 2016 and there were no unused tax credit carryforwards as of December 31, 2016.

Mortgage Banking Activities [Abstract]
MORTGAGE BANKING ACTIVITIES	MORTGAGE BANKING ACTIVITIES The Bank originates conforming single family residential mortgage loans and sells these loans in the secondary market. The amount of net revenue on mortgage banking activities is a function of mortgage loans originated for sale and the fair values of these loans and related derivatives. Net revenue on mortgage banking activities includes mark to market pricing adjustments on loan commitments and forward sales contracts, initial capitalized value of MSRs and gain on sale of MSRs. During the year ended December 31, 2016 , the Bank originated $5.14 billion and sold $5.13 billion of conforming single family residential mortgage loans in the secondary market. The net gain and margin were $148.2 million and 2.89 percent , respectively, and loan origination fees were $18.9 million for the year ended December 31, 2016 .

RISK MANAGEMENT AND DERIVATIVE

RISK MANAGEMENT AND DERIVATIVE INSTRUMENTS	12 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
RISK MANAGEMENT AND DERIVATIVE INSTRUMENTS	RISK MANAGEMENT AND DERIVATIVE INSTRUMENTS The Company uses derivative instruments and other risk management techniques to reduce its exposure to adverse fluctuations in interest rates and foreign exchange rates in accordance with its risk management policies. The Company utilizes forward contracts and investor commitments to economically hedge mortgage banking products and may from time to time use interest rate swaps as hedges against certain liabilities. 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 Consolidated Statements of Operations. The fair value of resulting derivative assets and liabilities are included in Other Assets and Accrued Expenses and Other Liabilities, respectively, in the Consolidated Statements of Financial Condition. The net gains (losses) relating to these derivative instruments used for mortgage banking activities are $2.2 million , $(8.0) million and $(17.3) million for the years ended December 31, 2016 , 2015 , and 2014 , respectively, and are included in Net Revenue on Mortgage Banking Activities in the Consolidated Statements of Operations. 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 of $75.0 million . At September 30, 2015, the Company exited the underlying hedged items related to interest rate swaps designated as cash flow hedges. As a result, the Company discontinued hedge accounting related to these interest rate swaps, and reclassified the fair value of the derivatives from AOCI into earnings. At September 30, 2015, the fair value of these derivative instruments discontinued from hedge accounting was $918 thousand , which was reclassified into earnings. Interest Rate Swaps and Caps on Loans: 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 identical 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. During the year ended December 31, 2016 , 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. For the year ended December 31, 2016 , changes in fair value recorded in Other Income in the Consolidated Statements of Operations were $29 thousand . The following table presents the amount and market value of derivative instruments included in the Consolidated Statements of Financial Condition as of the dates indicated. Note 3 contains further disclosures pertaining to the fair value of mortgage banking derivatives.

However, the Company elected to account for all derivatives with counterparty institutions on a gross basis. There was no cash collateral received against derivative assets at December 31, 2016 and 2015 . Cash collateral pledged against derivative liabilities recorded in Other Assets in Consolidated Statements of Financial Condition were $0 and $590 thousand at December 31, 2016 and 2015 , respectively.

EMPLOYEE STOCK COMPENSATION	EMPLOYEE STOCK COMPENSATION Share-based Compensation Expense For the years ended December 31, 2016 , 2015 , and 2014 , share-based compensation expense on stock option awards, restricted stock awards and restricted stock units was $11.9 million , $9.1 million , and $6.3 million respectively, and the related tax benefits were $5.0 million , $3.8 million and $2.7 million , respectively. Share-based compensation expense on stock appreciation rights was $18 thousand , $202 thousand , and $2.0 million , respectively, and the related tax benefits were $7 thousand , $85 thousand , and $827 thousand , respectively, for the years ended December 31, 2016 , 2015 , and 2014 . On July 16, 2013, the Company’s stockholders approved the Company’s 2013 Omnibus Stock Incentive Plan (the 2013 Omnibus Plan). Upon the approval of the 2013 Omnibus Plan, the Company ceased being able to grant new awards under the Company’s 2011 Omnibus Incentive Plan or any prior equity incentive plans. The 2013 Omnibus Plan provides that the aggregate number of shares of Company common stock that may be subject to awards under the 2013 Omnibus Plan will be 20 percent of the then outstanding shares of Company common stock (the Share Limit), provided that in no event will the Share Limit be less than the greater of 2,384,711 shares of Company common stock and the aggregate number of shares of Company common stock with respect to which awards have been properly granted under the 2013 Omnibus Plan up to that point in time. As of December 31, 2016 , based on the number of shares then-registered for issuance under the 2013 Omnibus Plan, 1,432,221 shares were available for future awards under the 2013 Omnibus Plan. The Company established the SECT to fund future employee stock compensation and benefit obligations of the Company during the year ended December 31, 2016 . There were no shares funded out of the SECT during the year ended December 31, 2016 . See Note 18 for additional information. Unrecognized Share-based Compensation Expense The following table presents unrecognized share-based compensation expense as of December 31, 2016 : Unrecognized Expense Average Expected Recognition Period ($ in thousands) Stock option awards $ 1,309 3.6 years Restricted stock awards and restricted stock units 11,965 2.8 years Stock appreciation rights $ 2 0.4 years Total $ 13,276 2.9 years Stock Options The Company has issued stock options to certain employees, officers and directors. Stock options are issued at the closing market price immediately before the grant date, and generally have a three to five year vesting period and contractual terms of seven to ten years. The weighted-average estimated fair value per share options granted was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions. Year Ended December 31, 2016 2015 2014 ($ in thousands, except per share data) Granted date fair value of options granted $ 1,630 $ 729 $ 781 Fair value of options vested $ 497 $ 481 $ 346 Total intrinsic value of options exercised $ 722 $ 75 $ 110 Cash received from options exercised $ — $ 501 $ 993 Weighted-average estimated fair value per share of options granted $ 5.09 $ 3.76 $ 3.38 Expected volatility was determined based on the historical monthly volatility of our stock price over a period equal to the expected term of the options granted. The expected term of the options represents the period that options granted are expected to be outstanding based primarily on the historical exercise behavior associated with previous options grants. The risk-free interest rate was based on the U.S. Treasury yield curve at the time of grant for a period equal to the expected term of the options granted. The following table presents a summary of weighted-average assumptions used for calculating fair value options for the periods indicated: Year Ended December 31, 2016 2015 2014 Weighted-average assumptions Dividend yield 3.57 % 4.14 % 3.69 % Expected volatility 43.30 % 43.04 % 40.26 % Expected term 6.5 years 6.4 years 6.0 years Risk-free interest rate 1.61 % 1.68 % 1.99 % The following table represents stock option activity and weighted-average exercise price per share for the periods indicated: Year Ended December 31, 2016 2015 2014 Number of Shares Weighted- Average Exercise Price per Share Number of Weighted- Number of Weighted- Outstanding at beginning of year 960,879 $ 12.86 879,070 $ 12.67 734,721 $ 12.73 Granted 320,000 $ 16.78 193,696 $ 13.28 231,016 $ 12.05 Cash settled 55,826 $ 14.33 — $ — — $ — Exercised (51,666 ) $ 11.48 (43,333 ) $ 11.55 (86,667 ) $ 11.46 Forfeited (202,743 ) $ 13.84 (68,554 ) $ 12.38 — $ — Expired (2,053 ) $ 13.88 — $ — — $ — Outstanding at end of year 968,591 $ 13.95 960,879 $ 12.86 879,070 $ 12.67 Exercisable at end of year 449,655 $ 12.68 394,613 $ 12.70 166,016 $ 11.28 The following table represents changes in unvested stock options and related information as of and for the periods indicated: Year Ended December 31, 2016 2015 2014 Number of Shares Weighted- Average Exercise Price per Share Number Weighted- Number Weighted- Outstanding at beginning of year 566,266 $ 12.99 552,672 $ 12.74 419,569 $ 13.16 Granted 320,000 $ 16.77 193,696 $ 13.28 231,016 $ 12.05 Vested (170,837 ) $ 12.81 (170,102 ) $ 12.57 (97,913 ) $ 12.94 Forfeited (196,493 ) $ 13.86 (10,000 ) $ 12.03 — $ — Outstanding at end of year 518,936 $ 15.04 566,266 $ 12.99 552,672 $ 12.74 The following table presents a summary of stock options outstanding as of December 31, 2016 : Options Outstanding Options Exercisable Number Intrinsic Value Weighted- Weighted- Contractual Life Number Intrinsic Value Weighted- Weighted- $10.89 to $12.21 142,683 $ 829,472 $ 11.54 5.8 years 116,055 $ 674,091 $ 11.54 5.4 years $12.21 to $13.53 478,334 2,203,387 $ 12.74 7.2 years 262,990 1,258,879 $ 12.56 6.8 years $13.53 to $14.85 74,696 252,986 $ 13.96 8.0 years 37,732 120,715 $ 14.15 8.0 years $14.85 to $16.17 32,878 50,632 $ 15.81 4.5 years 32,878 50,632 $ 15.81 4.5 years $16.17 to $17.50 240,000 — $ 17.50 9.2 years — — $ — 0.0 years Total 968,591 $ 3,336,477 $ 13.95 7.5 years 449,655 $ 2,104,317 $ 12.68 6.4 years Restricted Stock Awards and Restricted Stock Units The Company also has granted restricted stock awards and restricted stock units to certain employees, officers and directors. The restricted stock awards and units are valued at the closing price of the Company’s stock on the date of award. The restricted stock awards and units fully vest after a specified number of years (ranging from one to five years ) of continued service from the date of grant. The Company recognizes an income tax deduction in an amount equal to the taxable income reported by the holders of the restricted stock, generally when vested or, in the case of restricted stock units, when settled. The following table represents restricted stock awards and restricted stock units activity for the periods indicated: Year Ended December 31, 2016 2015 2014 Number of Shares Weighted- Average Price per Share Number of Shares Weighted- Average Price per Share Number of Weighted- Outstanding at beginning of year 1,516,361 $ 12.40 1,287,302 $ 12.53 893,886 $ 13.78 Granted (1) 1,711,968 $ 17.99 930,830 $ 12.31 915,077 $ 11.77 Vested (758,999 ) $ 13.12 (451,196 ) $ 12.64 (261,952 ) $ 13.51 Forfeited (1) (1,052,186 ) $ 13.92 (250,575 ) $ 12.29 (259,709 ) $ 13.21 Outstanding at end of year 1,417,144 $ 16.16 1,516,361 $ 12.40 1,287,302 $ 12.53 (1) The number of granted shares includes aggregate performance-based shares of 602,671 and 62,552 , respectively, for the years ended December 31, 2016 and 2015 . The number of forfeited shares includes aggregate performance-based shares of 615,223 and 0 , respectively, for the years ended December 31, 2016 and 2015 . The grant date fair value of the performance-based shares are not considered for the weighted average grant date fair value per share. These awards are linked to certain performance conditions relating to profitability and regulatory standing and actual amounts of stock released upon vesting will be determined by the Compensation Committee of the Company's Board of Directors upon the Committee's certification of the satisfaction of the target level of performance. Stock Appreciation Rights On August 21, 2012, the Company granted to 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 the former chief executive officer to dividend equivalent rights and originally contained an anti-dilution provision pursuant to which additional SARs (Additional SARs) were issued to the former chief executive officer 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, the former chief executive officer 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. As more fully described in Note 27, 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 and the aforementioned performance-based restricted stock award) 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 TEUs 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 18. 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. The weighted-average estimated fair value per share of SARs granted was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions.

Equity [Abstract]
SHAREHOLDERS' 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, as more fully described in Note 27), 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 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. As of September 30, 2016 and December 31, 2016, based on Jason Sugarman’s irrevocable election, warrants to purchase 50,000 and 130,000 shares, respectively, had been exercised, resulting in an issuance of 25,051 and 64,962 shares, respectively, of the Company's voting common stock. 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, as of December 31, 2016, 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 $8.72 per share as of December 31, 2016 . The terms and issuance of the foregoing warrants were approved by the Company's stockholders at a special meeting held on October 25, 2010. Common Stock On May 21, 2014 , the Company issued 5,150,000 shares of its voting common stock in an underwritten public offering and for gross proceeds of approximately $50.4 million and 772,500 shares of voting common stock upon the exercise in full by the underwriters of the underwritten public offering of their 30 -day over-allotment option, for additional gross proceeds of approximately $7.6 million . On November 7, 2014 , the Company completed the issuance and sale of 3,288,947 shares of its voting common stock to OCM BOCA Investor, LLC (Oaktree), an entity owned by investment funds managed by Oaktree Capital Management, L.P., and 1,900,000 shares of its voting common stock to Patriot Financial Partners, L.P., Patriot Financial Partners Parallel, L.P., Patriot Financial Partners II, L.P. and Patriot Financial Partners Parallel II, L.P, for gross proceeds of $49.9 million . 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 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 December 31, 2016 . 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 Company also granted the underwriters a 30 -day option to purchase up to an additional 600,000 depositary shares to cover over-allotments, which the underwriters exercised in full concurrently, resulting in additional gross proceeds of $14.5 million . A total of 115,000 shares of Series D Non-Cumulative Perpetual Preferred Stock were issued. 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 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 December 31, 2016 , a total of 1,337,544 Purchase Contracts had been settled early by their holders, resulting in the issuance by the Company of 5,946,170 shares of voting common stock. As of December 31, 2016 , 42,456 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 December 31, 2016 and 2015 , the Amortizing Notes, net of unamortized discounts, totaled $2.7 million and $7.5 million , respectively, net of unamortized discounts, and were included in Long Term Debt in the Consolidated Statements of Financial Condition. Change in Accumulated Other Comprehensive Income The Company’s AOCI includes unrealized gain (loss) on securities available-for-sale and unrealized gain on cash flow hedge. Changes to AOCI are presented net of tax effect as a component of equity. Reclassifications from AOCI are recorded in the Consolidated Statements of Operations either as a gain or loss.

REGULATORY CAPITAL MATTERS

REGULATORY CAPITAL MATTERS	12 Months Ended

Banking and Thrift [Abstract]
REGULATORY CAPITAL MATTERS	REGULATORY CAPITAL MATTERS The Company and the Bank are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Management believes as of December 31, 2016 , the Company and the Bank met all capital adequacy requirements to which they were then subject. With respect to the Bank, prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If only adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At December 31, 2016 , the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category. The following table presents the regulatory capital amounts and ratios for the Company and the Bank as of dates indicated: Amount Minimum Capital Requirements Minimum Required to Be Well Capitalized Under Prompt Corrective Action Provisions Amount Ratio Amount Ratio Amount Ratio ($ in thousands) December 31, 2016 Banc of California, Inc.

In addition to the risk-based guidelines, through December 31, 2014 the FRB required bank holding companies to maintain a minimum ratio of Tier 1 capital to average total assets, referred to as the leverage ratio, of 4.0 percent. Through December 31, 2014, in order to be considered “well capitalized,” federal bank regulatory agencies required depository institutions such as the Bank to maintain a minimum ratio of qualifying total capital to risk-weighted assets of 10.0 percent, a minimum ratio of Tier 1 capital to risk-weighted assets of 6.0 percent and a minimum ratio of Tier 1 capital to average total assets, referred to as the leverage ratio, of 5.0 percent. In July 2013, the Federal banking regulators approved a final rule to implement the revised capital adequacy standards of the Basel Committee on Banking Supervision, commonly called Basel III, and to address relevant provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act). The final rule strengthens the definition of regulatory capital, increases risk-based capital requirements, makes selected changes to the calculation of risk-weighted assets, and adjusts the prompt corrective action thresholds. The Company and the Bank became subject to the new rule on January 1, 2015 and certain provisions of the new rule will be phased in through 2019. The final rule: • Permits banking organizations that had less than $15 billion in total consolidated assets as of December 31, 2009, to include in Tier 1 capital trust preferred securities and cumulative perpetual preferred stock that were issued and included in Tier 1 capital prior to May 19, 2010, subject to a limit of 25 percent of Tier 1 capital elements, excluding any non-qualifying capital instruments and after all regulatory capital deductions and adjustments have been applied to Tier 1 capital. • Establishes new qualifying criteria for regulatory capital, including new limitations on the inclusion of deferred tax assets and mortgage servicing rights. • Requires a minimum ratio of common equity Tier 1 capital to risk-weighted assets of 4.5 percent. • Increases the minimum Tier 1 capital to risk-weighted assets ratio requirement from 4 percent to 6 percent. • Retains the minimum total capital to risk-weighted assets ratio requirement of 8 percent. • Retains a minimum leverage ratio requirement of 4 percent. • Changes the prompt corrective action standards so that in order to be considered well-capitalized, a depository institution must have a ratio of common equity Tier 1 capital to risk-weighted assets of 6.5 percent (new), a ratio of Tier 1 capital to risk-weighted assets of 8 percent (increased from 6 percent), a ratio of total capital to risk-weighted assets of 10 percent (unchanged), and a leverage ratio of 5 percent (unchanged). • Retains the existing regulatory capital framework for one-to-four family residential mortgage exposures. • Permits banking organizations that are not subject to the advanced approaches rule, such as the Company and the Bank, to retain, through a one-time election, the existing treatment for most accumulated other comprehensive income, such that unrealized gains and losses on securities available-for-sale will not affect regulatory capital amounts and ratios. • Implements a new capital conservation buffer requirement for a banking organization to maintain a common equity capital ratio more than 2.5 percent above the minimum common equity Tier 1 capital, Tier 1 capital and total risk based capital ratios in order to avoid limitations on capital distributions, including dividend payments, and certain discretionary bonus payments. The capital conservation buffer requirement will be phased in beginning on January 1, 2016 at 0.625 percent and will be fully phased in at 2.50 percent by January 1, 2019. A banking organization with a buffer of less than the required amount would be subject to increasingly stringent limitations on such distributions and payments as the buffer approaches zero. The new rule also generally prohibits a banking organization from making such distributions or payments during any quarter if its eligible retained income is negative and its capital conservation buffer ratio was 2.5 percent or less at the end of the previous quarter. The eligible retained income of a banking organization is defined as its net income for the four calendar quarters preceding the current calendar quarter, based on the organization’s quarterly regulatory reports, net of any distributions and associated tax effects not already reflected in net income. • Increases capital requirements for past-due loans, high volatility commercial real estate exposures, and certain short term commitments and securitization exposures. • Expands the recognition of collateral and guarantors in determining risk-weighted assets. • Removes references to credit ratings consistent with the Dodd Frank Act and establishes due diligence requirements for securitization exposures. Dividend Restrictions The Company’s principal source of funds for dividend payments is dividends received from the Bank. Federal banking laws and regulations limit the amount of dividends that may be paid without prior approval of regulatory agencies. Under these regulations, in the case of the Bank, the amount of dividends that may be paid in any calendar year is limited to the current year’s net profits, combined with the retained net profits of the preceding two years, subject to the capital requirements described above. For the year ended December 31, 2016 , the Bank had $98.2 million plus any net profits generated in 2016 available to pay dividends to the Company.

VARIABLE INTEREST ENTITIES

VARIABLE INTEREST ENTITIES	12 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 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 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 this partnership, which was formed to invest in newly installed residential rooftop solar leases and power purchase agreements. As a result of its investment, 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 partnership 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 entity including operational and credit risk management activities. As the Company is not the primary beneficiary, the Company did not consolidate the entity. Accordingly, the Company uses the Hypothetical Liquidation at Book Value (HLBV) method to account for the investment 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 $57.3 million of its $100.0 million aggregate funding commitment into the partnership and recognized a loss on investment of $31.5 million through its HLBV application during the year ended December 31, 2016 . As a result, the balance of its investment was $25.6 million and was included in Other Assets in the Consolidated Statements of Financial Condition at December 31, 2016 . From an income tax benefit perspective, the Company recognized investment tax credits of $33.4 million as well as income tax benefits relating to the recognition of its loss through its HLBV application during the year ended December 31, 2016 . As the investment represents an unconsolidated VIE to the Company, the assets and liabilities of the investment itself 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: December 31, 2016 (In thousands) Equipment, net of depreciation $ 151,721 Other assets 351 Total unconsolidated assets $ 152,072 Total unconsolidated liabilities $ — Maximum loss exposure $ 68,298 The maximum loss exposure that would be absorbed by the Company in the event that all of the assets in the VIE are deemed worthless is $68.3 million , consisting of the investment balance of $25.6 million and $42.7 million of unfunded equity commitments at December 31, 2016 . 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 investment. In addition, the arrangement includes 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. The Company anticipates entering into similar partnerships in future periods as part of the Company’s tax planning strategies. 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 year ended December 31, 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 18 for additional information.

Earnings Per Share [Abstract]
EARNINGS PER COMMON SHARE	EARNINGS PER COMMON SHARE Net income (loss) allocated to common stockholders is computed by subtracting income allocated to participating securities, participating securities dividends and preferred stock dividend from net income. Participating securities are instruments granted in share-based payment transactions that contain rights to receive nonforfeitable dividends or dividend equivalents, which includes the SARs as they confer dividend equivalent rights, as described under “Stock Appreciation Rights” in Note 16. Basic EPS is computed by dividing net income allocated to common stockholders by the weighted average number of shares outstanding, including the minimum number of shares issuable under purchase contracts relating to the tangible equity units. Diluted EPS is computed by dividing net income (loss) allocated to common stockholders by the weighted average number of shares outstanding, adjusted for the dilutive effect of the restricted stock units, the potentially issuable shares in excess of the minimum under purchase contracts relating to the tangible equity units, outstanding stock options, and warrants to purchase common stock. Computations for basic and diluted EPS are provided below: Year Ended December 31, 2016 2015 2014 Common Stock Class B Common Stock Total Common Class B Total Common Class B Total ($ in thousands, except per share data) Basic: Net income $ 115,097 $ 319 $ 115,416 $ 62,050 $ 22 $ 62,072 $ 29,559 $ 646 $ 30,205 Less: income allocated to participating securities (2,268 ) (6 ) (2,274 ) (1,310 ) — (1,310 ) (487 ) (11 ) (498 ) Less: participating securities dividends (757 ) (2 ) (759 ) (713 ) — (713 ) (531 ) (12 ) (543 ) Less: preferred stock dividends (19,859 ) (55 ) (19,914 ) (9,820 ) (3 ) (9,823 ) (3,562 ) (78 ) (3,640 ) Net income allocated to common stockholders $ 92,213 $ 256 $ 92,469 $ 50,207 $ 19 $ 50,226 $ 24,979 $ 545 $ 25,524 Weighted average common shares outstanding 46,699,050 129,413 46,828,463 37,033,725 12,869 37,046,594 27,444,878 599,563 28,044,441 Basic earnings per common share $ 1.97 $ 1.97 $ 1.97 $ 1.36 $ 1.36 $ 1.36 $ 0.91 $ 0.91 $ 0.91 Diluted: Net income allocated to common stockholders $ 92,213 $ 256 $ 92,469 $ 50,207 $ 19 $ 50,226 $ 24,979 $ 545 $ 25,524 Additional income allocation for class B dilutive shares (775 ) 775 — (520 ) 520 — (106 ) 106 — Adjusted net income allocated to common stockholders $ 91,438 $ 1,031 $ 92,469 $ 49,687 $ 539 $ 50,226 $ 24,873 $ 651 $ 25,524 Weighted average common shares outstanding 46,699,050 129,413 46,828,463 37,033,725 12,869 37,046,594 27,444,878 599,563 28,044,441 Add: Dilutive effects of restricted stock units 218,121 — 218,121 138,646 — 138,646 52,286 — 52,286 Add: Dilutive effects of purchase contracts — — — — — — 26,807 — 26,807 Add: Dilutive effects of stock options 197,435 — 197,435 30,014 — 30,014 8,692 — 8,692 Add: Dilutive effects of warrants — 394,086 394,086 — 383,255 383,255 — 115,997 115,997 Average shares and dilutive common shares 47,114,606 523,499 47,638,105 37,202,385 396,124 37,598,509 27,532,663 715,560 28,248,223 Diluted earnings per common share $ 1.94 $ 1.97 $ 1.94 $ 1.34 $ 1.36 $ 1.34 $ 0.90 $ 0.91 $ 0.90 For the years ended December 31, 2016 , 2015 , and 2014 , there were 272,878 , 498,196 and 658,054 stock options, respectively, that were not considered in computing diluted earnings per common share, because they were anti-dilutive.

Commitments and Contingencies Disclosure [Abstract]
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. The contractual amount of financial instruments with off-balance-sheet risk was as follows for the dates indicated: December 31, 2016 2015 Fixed Rate Variable Rate Fixed Rate Variable Rate (In thousands) Commitments to extend credit $ 74,777 $ 201,321 $ 40,312 $ 99,026 Unused lines of credit 27,151 888,236 6,044 508,295 Letters of credit 1,784 8,655 2,611 11,278 Commitments to make loans are generally made for periods of 30 days or less. As of December 31, 2016 , total forward commitments were $802.8 million . These commitments consisted of TBAs of $747.0 million and best efforts of $55.8 million . Additionally, the Company had IRLCs of $312.6 million and foreign exchange contracts of $8.4 million at December 31, 2016 . 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.

SEGMENT REPORTING

SEGMENT REPORTING	12 Months Ended

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING The Company utilizes an internal reporting system to measure the performance of various operating segments within the Bank and the Company overall. The Company had three operating segments for purposes of management reporting: (i) Commercial Banking; (ii) Mortgage Banking; and (iii) Corporate/Other at December 31, 2016. The Company sold all of its membership interests in The Palisades Group on May 5, 2016 and ceased Financial Advisory activities through this segment (see Note 2 for additional information). The principal business of the Commercial Banking segment consists of attracting deposits and investing these funds primarily in commercial, consumer and real estate secured loans. The principal business of the Mortgage Banking segment is originating conforming SFR loans and selling these loans in the secondary market. The Corporate/Other segment includes the holding company. The Corporate/Other segment engages in business activities through the sale of assets, other real estate owned and loans held at the holding company and incurs interest expense on debt as well as non-interest expense for corporate related activities. The principal business of the Financial Advisory segment was operated by The Palisades Group and provided services related to the purchase, sale and management of SFR mortgage loans. During the fourth quarter of 2015, the Company developed a measurement method to allocate centrally incurred costs to its operating segments. The Company allocates shared service costs within Commercial Banking noninterest expense, as well as Corporate/Other noninterest expense, to the respective operating segments. The cost allocation was done on a comparable basis. These allocations of centrally incurred costs resulted in a reduction of noninterest expense for Commercial Banking and Corporate/Other, in the amount of $10.5 million and $21.0 million , respectively, for the year ended December 31, 2016 , and $7.1 million and $13.8 million , respectively, for the year ended December 31, 2015 . Additionally, these allocations resulted in an increase of noninterest expense for Mortgage Banking and Financial Advisory, in the amount of $30.8 million and $760 thousand , respectively, for the year ended December 31, 2016 , and $19.3 million and $1.6 million , respectively, for the year ended December 31, 2015 . The Company did not change the measurement method of prior period operating segment information, as it was not deemed practicable to do so. The following table represents the operating segments’ financial results and other key financial measures as of or for the years ended December 31, 2016 , 2015 , and 2014 : As of or For the Year Ended Commercial Banking Mortgage Banking Financial Advisory Corporate/ Other Inter-Segment Elimination Consolidated (In thousands) December 31, 2016 Net interest income (loss) $ 323,060 $ 15,108 $ — $ (12,695 ) $ — $ 325,473 Provision for loan and lease losses 5,271 — — — — 5,271 Noninterest income 91,615 172,245 2,636 7,033 (1,649 ) 271,880 Noninterest expense 268,277 170,113 3,198 2,737 (1,649 ) 442,676 Income (loss) before income taxes $ 141,127 $ 17,240 $ (562 ) $ (8,399 ) $ — $ 149,406 Total assets $ 10,543,134 $ 443,583 $ — $ 256,783 $ (213,647 ) $ 11,029,853 December 31, 2015 Net interest income (loss) $ 225,869 $ 12,502 $ — $ (14,654 ) $ — $ 223,717 Provision for loan and lease losses 7,469 — — — — 7,469 Noninterest income 65,829 144,522 15,960 — (6,092 ) 220,219 Noninterest expense 183,918 143,912 10,463 — (6,092 ) 332,201 Income (loss) before income taxes $ 100,311 $ 13,112 $ 5,497 $ (14,654 ) $ — $ 104,266 Total assets $ 7,785,887 $ 445,509 $ 11,865 $ 157,944 $ (165,650 ) $ 8,235,555 December 31, 2014 Net interest income (loss) $ 154,322 $ 8,455 $ — $ (7,500 ) $ — $ 155,277 Provision for loan and lease losses 10,976 — — — — 10,976 Noninterest income 34,122 98,322 19,697 217 (6,721 ) 145,637 Noninterest expense 150,539 96,103 11,071 12,480 (6,721 ) 263,472 Income (loss) before income taxes $ 26,929 $ 10,674 $ 8,626 $ (19,763 ) $ — $ 26,466 Total assets $ 5,648,986 $ 309,241 $ 14,957 $ 60,593 $ (62,480 ) $ 5,971,297

Excluding the loan amounts described in detail below, loans outstanding to officers and directors and their related interests amounted to $249 thousand and $236 thousand at December 31, 2016 and 2015 , respectively, each of which were performing in accordance with their respective terms. These loans are made in the ordinary course of business and on substantially the same terms and conditions, including interest rates and collateral, as those of comparable transactions with non-insiders prevailing at the time, in accordance with the Bank’s underwriting guidelines, and do not involve more than the normal risk of collectability or present other unfavorable features. The Bank has an Employee Loan Program (the Program) which is available to all employees and offers executive officers, directors and principal stockholders that meet the eligibility requirements the opportunity to participate on the same terms as employees generally, provided that any loan to an executive officer, director or principal stockholder must be approved by the Bank’s Board of Directors. The sole benefit provided under the Program is a reduction in loan fees. Deposits from principal officers, directors, and their related interests amounted to $2.4 million and $2.5 million at December 31, 2016 and 2015 , respectively. There are certain deposits described below, which are not included in the foregoing amounts. Indemnification for Costs of Counsel in Connection with Special Committee Investigation . On November 3, 2016, in connection with the investigation by the Special Committee of the Company’s Board of Directors described in Note 27, the Board authorized and directed the Company to provide indemnification, advancement and/or reimbursement for the costs of separate independent counsel retained by any then-current officer or director, in their individual capacity, with respect to matters related to the investigation, and to advise them on their rights and obligations with respect to the investigation. At the Board’s direction, this indemnification, advancement and/or reimbursement is, to the extent applicable, subject to the indemnification agreement that each officer and director previously entered into with the Company, which includes an undertaking to repay any expenses advanced if it is ultimately determined that the officer or director was not entitled to indemnification under such agreements and applicable law. During the year ended December 31, 2016, fees and expenses incurred under the arrangement described above (which the Company paid in January 2017) included $573 thousand incurred by the Company’s then- (now former) Chairman, President and Chief Executive Officer Steven A.

Effective August 8, 2016, the Bank provided $40.3 million out of a $145.0 million committed construction line of credit (the Stadco Loan) to LAFC Stadium Co, LLC (Stadco) for the construction of a soccer-specific stadium for the Los Angeles Football Club (LAFC) in Los Angeles, California as well as to fund the interest and fees that become due under the Stadco Loan. LAFC is a Major League Soccer expansion franchise scheduled to debut in 2018. Also effective August 8, 2016, the Bank provided $9.7 million out of a $35.0 million committed senior secured line of credit (the Team Loan) to LAFC Sports, LLC (Team) to fund distributions to LAFC Partners, LLLP (Holdco) that will be used for stadium construction, funding interest and fees that become due under such Team Loan and to pay all other fees, costs and expenses payable by the Team in connection with project costs related to the stadium construction. All of the outstanding equity interests in Stadco and Team are held by Holdco, and Holdco serves a sole guarantor of the Team Loan described above.

As of December 31, 2016, there were no outstanding advances by the Bank under the Stadco Loan, and the Bank collected $59 thousand in unused loan fees during the year ended December 31, 2016.

Following the closing of the Stadco Loan and the Term Loan, the Bank on August 22, 2016 reached agreement with the Team concerning, among other things, the Bank’s right to name the stadium to be operated by Stadco (the Stadium) as “Banc of California Stadium.” The August 22, 2016 agreement, which contemplated the negotiation and execution of more detailed definitive agreements between the Bank, on the one hand, and Stadco and the Team on the other hand (LAFC Transaction), also included a sponsorship relationship between the Bank and the Team with an initial term ending on the completion date of LAFC’s 15 th full Major League Soccer (MLS) season, and the Bank having a right of first offer to extend the term for an additional 10 years (LAFC Term). On February 28, 2017, the Bank executed more detailed definitive agreements with LAFC and Stadco relating to the LAFC Transaction, which are subject to MLS rules and/or approval (the LAFC Agreements). The LAFC Agreements provide that, during the LAFC Term, the Bank will have the exclusive right to name the Stadium and will be the exclusive provider of financial services to (and the exclusive financial services sponsor of) the Team and Stadco. In connection with its right to name the Stadium, the Bank will receive, among other rights, signage (including prominent exterior signage) and related branding rights throughout the exterior and interior of the Stadium facility (including exclusive branding rights within certain designated areas and venues within the facility), will receive the right to locate a Bank branch within the Stadium facility, will receive the exclusive right to install and operate ATMs in the Stadium facility, and will receive the exclusive right to process payments and provide other financial services (with certain exceptions) throughout the facility. In addition, the Bank will receive suite access for LAFC and certain other events held at the Stadium and will receive certain hospitality, event, media and other rights ancillary to its naming rights relating to the Stadium and its sponsorship rights relating to the Team. In conjunction with the LAFC Agreements, the Company expects to decrease its planned marketing and sponsorship expenses.

On August 4, 2016, the Bank entered into a Management Services Agreement with Carlos Salas, who was, at the time, the Chief Executive Officer of COR Clearing LLC (COR Clearing) and Chief Financial Officer of COR Securities Holding, Inc. (CORSHI). Steven A. Sugarman, the then- (now former) Chairman, President and Chief Executive Officer of the Company and the Bank, is the Chief Executive Officer, as well as a controlling equity owner, of both COR Clearing and CORSHI. For management consulting and advisory services provided to the Bank through the termination of the management services agreement on November 30, 2016, Mr. Salas earned $108 thousand in fees. On December 1, 2016, Mr. Salas became a full-time employee of the Bank and tendered his resignation from his positions as Chief Executive Officer of COR Clearing and Chief Financial Officer of CORSHI effective upon the orderly transition of his duties, but in no case later than March 31, 2017. Mr. Salas earned $17 thousand as a full time employee of the Bank through the year ended December 31, 2016. Mr. Salas separated from the Bank on February 1, 2017. TCW Affiliates . TCW Shared Opportunity Fund V, L.P. (SHOP V Fund), an affiliate of The TCW Group, Inc., initially became a holder of the Company’s voting common stock and non-voting common stock as a lead investor in the November 2010 recapitalization of the Company (the Recapitalization). In connection with its investment in the Recapitalization, SHOP V Fund also was issued by the Company an immediately exercisable five -year warrant (the SHOP V Fund Warrant) to purchase 240,000 shares of non-voting common stock or, to the extent provided therein, shares of voting common stock in lieu of non-voting common stock. SHOP V Fund was issued shares of non-voting common stock in the Recapitalization because at that time, a controlling interest in TCW Asset Management Company, the investment manager to SHOP V Fund, was held by a foreign banking organization, and in order to prevent SHOP V Fund from being considered a bank holding company under the Bank Holding Company Act of 1956, as amended, the number of shares of voting common stock it purchased in the Recapitalization had to be limited to 4.99 percent of the total number of shares of voting common stock outstanding immediately following the Recapitalization. For the same reason, the SHOP V Fund Warrant could be exercised by SHOP V Fund for voting common stock in lieu of non-voting common stock only to the extent SHOP V Fund's percentage ownership of the voting common stock at the time of exercise would be less than 4.99 percent as a result of dilution occurring from additional issuances of voting common stock subsequent to the Recapitalization. In 2013, the foreign banking organization sold its controlling interest in TCW Asset Management Company, eliminating the need to limit SHOP V Fund's percentage ownership of the voting common stock to 4.99 percent . As a result, on May 29, 2013, the Company and SHOP V Fund entered into a Common Stock Share Exchange Agreement, dated May 29, 2013 (Exchange Agreement), pursuant to which SHOP V Fund could from time to time exchange its shares of non-voting common stock for shares of voting common stock issued by the Company on a share-for-share basis, provided that immediately following any such exchange, SHOP V Fund's percentage ownership of voting common stock did not exceed 9.99 percent . The shares of non-voting common stock that could be exchanged by SHOP V Fund pursuant to the Exchange Agreement included the shares of non-voting common stock it purchased in the Recapitalization, the additional shares of non-voting common stock SHOP V Fund acquired subsequent to the Recapitalization pursuant to the Company’s Dividend Reinvestment Plan and any additional shares of non-voting common stock that SHOP V Fund acquired pursuant to its exercise of the SHOP V Fund Warrant. On December 10, 2014, SHOP V Fund and two affiliated entities, Crescent Special Situations Fund Legacy V, L.P. (CSSF Legacy V) and Crescent Special Situations Fund Investor Group, L.P. (CSSF Investor Group), entered into a Contribution, Distribution and Sale Agreement pursuant to which SHOP V Fund agreed to transfer shares of non-voting common stock and portions of the SHOP V Fund Warrant to CSSF Legacy V and CSSF Investor Group. Also on December 10, 2014, SHOP V Fund, CSSF Legacy V, CSSF Investor Group and the Company entered into an Assignment and Assumption Agreement pursuant to which all of SHOP V Fund’s rights and obligations under the Exchange Agreement with respect to the shares of non-voting common stock transferred by it to CSSF Legacy V and CSSF Investor Group pursuant to the Contribution, Distribution and Sale Agreement were assigned to CSSF Legacy V and CSSF Investor Group, including the right of SHOP V Fund to exchange such shares for shares of voting common stock on a one -for-one basis. Based on a Schedule 13-G amendment filed with the SEC on February 12, 2015, The TCW Group's last public filing reporting ownership of the Company's securities, as of December 31, 2014, The TCW Group, Inc. and its affiliates held 1,318,462 shares of voting common stock (which included, for purposes of this calculation, the 240,000 shares of stock underlying the as yet unexercised SHOP V Fund Warrant). On June 3, 2013, January 5, 2015, January 20, 2015, and March 16, 2015, SHOP V Fund or CSSF Legacy V or CSSF Investor Group exchanged 550,000 shares, 522,564 shares, 86,620 shares, and 934 shares, respectively, of non-voting common stock for the same number of shares of voting common stock. In addition, on August 3, 2015, the SHOP V Fund Warrant, which was held in separate portions by CSSF Legacy V and CSSF Investor Group, was exercised in full using a cashless (net) exercise, resulting in a net number of shares of non-voting common stock issued in the aggregate of 70,690 , which were immediately thereafter exchanged for an aggregate of 70,690 shares of voting common stock. Based on automatic adjustments to the original $11.00 exercise price of the SHOP V Fund Warrant, the exercise price at the time of exercise was $9.13 per share. As a result of these exchanges and exercises The TCW Group, Inc. and its affiliates no longer hold any shares of non-voting common stock or warrants to acquire stock. Based on TCW Group's prior report of owning 1,318,462 shares of the Company’s voting common stock, TCW Group, Inc. would have owned 2.7 percent of the Company’s outstanding voting common stock as of December 31, 2016. Oaktree Affiliates. As reported in a Schedule 13-G filed with the SEC on January 16, 2015, OCM BOCA Investor, LLC (OCM), an affiliate of Oaktree Capital Management, L.P., owned 3,288,947 shares of the Company’s voting common stock as of November 7, 2014, which OCM reported represented 9.9 percent of the Company’s total shares outstanding as of the dates set forth in the Schedule 13-G. For the details of the transaction in which OCM acquired these shares, see “Securities Purchase Agreement with Oaktree.” However, as reported in a Schedule 13-G amendment filed with the SEC on February 12, 2016 OCM and its affiliates owned 671,702 shares of the Company’s voting common stock as of December 31, 2016, which OCM reported represented less than 5 percent of the Company’s total shares outstanding. Loans . Effective September 30, 2015, the Bank provides a $15.0 million committed revolving line of credit to Teleios LS Holdings DE, LLC and Teleios LS Holdings II DE, LLC (Teleios), which generate income through the purchase, monitoring, maintenance and maturity of life insurance policies. At the time the facility was executed, the Teleios entities were hedge funds in which Oaktree Capital Management L.P. or one of its affiliates was a controlling investor. Advances under the Teleios line of credit are secured by life insurance policies purchased by Teleios that have a market value in excess of the balance of the advances under the line of credit. As of December 31, 2016 and 2015, outstanding advances by the Bank (and the largest aggregate amount outstanding) under the Teleios line of credit were $15.0 million and $3.6 million , respectively. Interest on the outstanding balance under the Teleios line of credit accrues at the Prime Rate plus a margin. During the years ended December 31, 2016 and 2015, $2.0 million and no principal, respectively, and $462 thousand and $14 thousand in interest, respectively, was paid by Teleios on the line of credit to the Bank. Effective June 26, 2015, the Bank provided a $35.0 million committed revolving repurchase facility, which was increased to $45.0 million (the Sabal repurchase facility) effective October 7, 2016, to Sabal TL1, LLC, a Delaware limited liability company, with a maximum funding amount of $55.0 million in certain situations. At the time the facility was executed, Sabal TL1, LLC was controlled by an affiliate of Oaktree Capital Management, L.P. Under the Sabal repurchase facility, commercial mortgage loans originated by Sabal are purchased from Sabal by the Bank, together with a simultaneous agreement by Sabal to repurchase the commercial mortgage loans from the Bank at a future date. The advances under the Sabal repurchase facility are secured by commercial mortgage loans that have a market value in excess of the balance of the advances under the facility. During the years ended December 31, 2016 and 2015, the largest aggregate amount of principal outstanding under the Sabal repurchase facility was $55.1 million and $26.3 million , respectively. The amount outstanding as of December 31, 2016 and 2015 was $22.6 million and $26.3 million , respectively. Interest on the outstanding balance under the Sabal repurchase facility accrues at the six month LIBOR rate plus a margin. $514.1 million and $105.0 million in principal, respectively, and $1.1 million and $252 thousand in interest, respectively, was paid by Sabal on the facility to the Bank during the years ended December 31, 2016 and 2015. Securities Purchase Agreement with Oaktree . As noted above, as reported in a Schedule 13-G filed with the SEC on January 16, 2015, OCM owned 3,288,947 shares of the Company’s voting common stock. OCM purchased these shares from the Company on November 7, 2014 at a price of $9.78 per share pursuant to a securities purchase agreement entered into on April 22, 2014 (and amended on October 28, 2014) in order for the Company to raise a portion of the capital to be used to finance the acquisition of select assets and assumption of certain liabilities by the Bank from Banco Popular North America (BPNA) comprising BPNA’S network of 20 California branches (the BPNA Branch Acquisition), which was completed on November 8, 2014. In consideration for its commitment under the securities purchase agreement, OCM was paid at closing an equity support payment from the Company of $1.6 million . Management Services . Approximately nine months before OCM became a stockholder of the Company, certain affiliates of Oaktree Capital Management, L.P. (collectively, the Oaktree Funds) entered into a management agreement, effective January 30, 2014, as amended (the Management Agreement), with The Palisades Group, which was then a wholly owned subsidiary of the Company. Pursuant to the Management Agreement, The Palisades Group serves as the credit manager of pools of SFR mortgage loans held in securitization trusts or other vehicles beneficially owned by the Oaktree Funds. Under the Management Agreement, The Palisades Group is paid a monthly management fee primarily based on the amount of certain designated pool assets and may earn additional fees for advice related to financing opportunities. During the period from January 1, 2016 through May 5, 2016 (the date the Company sold its membership interests in The Palisades Group) and the years ended December 31, 2015 and 2014, the Oaktree Funds paid The Palisades Group $1.0 million , $5.1 million , and $5.3 million as management fees, respectively, which in some instances represents fees for partial year services.

Pursuant to the New Patriot SPA, substantially concurrently with the BPNA Branch Acquisition, Patriot Partners purchased from the Company (i) 1,076,000 shares of its voting common stock at a price of $9.78 per share and (ii) 824,000 shares of its voting common stock at a price of $11.55 per share, for an aggregate purchase price of $20.0 million . In consideration for Patriot’s commitment under the New SPA and pursuant the terms of the New SPA, on the closing of the sale of such shares on November 7, 2014, the Company paid Patriot an equity support payment of $538 thousand and also reimbursed Patriot $100 thousand in out-of-pocket expenses. On October 30, 2014, concurrent with the execution of the New Patriot SPA, Patriot and the Company entered into a Settlement Agreement and Release (the Settlement Agreement) in order to resolve, without admission of any wrongdoing by either party, a prior dispute regarding, among other things, the proper interpretation of certain provisions of the SPA, including but not limited to the computation of the purchase price per share (the Dispute). Pursuant to the Settlement Agreement, Patriot and the Company released any claims they may have had against the other party with respect to the Dispute. In addition, Patriot and the Company agreed for the period beginning on the date of the Settlement Agreement and ending on December 31, 2016, that neither Patriot nor the Company would disparage the other party or its affiliates. During the period beginning on the date of the Settlement Agreement and ending on December 31, 2016, Patriot also agreed not to: • institute, solicit, assist or join, as a party, any proxy solicitation, consent solicitation, board nomination or director removal relating to the Company against or involving the Company or any of its subsidiaries, affiliates, successors, assigns, directors, officers, employees, agents, attorneys or financial advisors; • take any action relative to the governance of the Company that would violate its passivity commitments or vote the shares of voting common stock held or controlled by it on any matters related to the election, removal or replacement of directors or the calling of any meeting related thereto, other than in accordance with management’s recommendations included in the Company’s proxy statement for any annual meeting or special meeting; • form or join in a partnership, limited partnership, syndicate or other group, or solicit proxies or written consents of stockholders or conduct any other type of referendum (binding or non-binding) with respect to, or from the holders of, the voting common stock and any other securities of the Company entitled to vote in the election of directors, or securities convertible into, or exercisable or exchangeable for, voting common stock or such other securities (such other securities, together with the voting common stock, being referred to as Voting Securities), or become a participant in or assist, encourage or advise any person in any solicitation of any proxy, consent or other authority to vote any Voting Securities; or • enter into any negotiations, agreements, arrangements or understandings with any person with respect to any of the foregoing or advise, assist, encourage or seek to persuade any person to take any action with respect to any of the foregoing. The Company also agreed, during the same period, not to: • institute, solicit, assist or join, as a party, any proxy solicitation, consent solicitation, board nomination or director removal relating to Patriot against or involving Patriot or any of its subsidiaries, affiliates, successors, assigns, officers, partners, principals, employees, agents, attorneys or financial advisors; or • enter into any negotiations, agreements, arrangements or understandings with any person with respect to any of the foregoing or advise, assist, encourage or seek to persuade any person to take any action with respect to any of the foregoing. St. Cloud Affiliates . On November 24, 2014, the Bank invested as a limited partner in an affiliate of St. Cloud Capital LLC (St. Cloud). Based on a Schedule 13-G amendment filed with the SEC on February 14, 2012, St. Cloud's last public filing reporting ownership of the Company securities, St. Cloud holds 700,538 shares of the Company’s voting common stock (approximately

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Line of Credit Covenant Waiver On November 29, 2016, the Company received, from the administrative agent and the lenders under the Company’s line of credit agreement, a waiver of the requirement under the credit agreement that the Company deliver its consolidated financial statements as of and for the three- and nine- month periods ended September 30, 2016 (the September 30, 2016 Financial Statements) to the administrative agent within 60 days after that date. The waiver effectively extended the time for delivering the September 30, 2016 Financial Statements to January 26, 2017. On January 25, 2017, the Company and the administrative agent and lenders under the credit agreement entered into an amendment to the line of credit agreement that further extended the time for the Company to deliver the September 30, 2016 Financial Statements to March 1, 2017. The line of credit had an outstanding balance of $68.0 million at January 25, 2017. Special Committee and Related Events Special Committee Investigation . On October 18, 2016, an anonymous blog post raised questions about related party transactions, director independence and other issues with respect to the Company, including suggestions that the Company was controlled by an individual who pled guilty to securities fraud in matters unrelated to the Company. In response to these allegations, the Board formed a Special Committee consisting solely of independent directors which commenced a process to identify and engage an independent law firm to review the allegations. Shortly thereafter, on October 27, 2016, the Company’s independent auditor, KPMG, sent a letter to Robert Sznewajs in his capacity as Chair of the Company’s Joint Audit Committee (the KPMG Letter) raising concerns about allegations of “inappropriate relationships with third parties” and “potential undisclosed related party relationships.” On October 30, 2016, the Special Committee retained WilmerHale, a law firm with no prior relationship with the Company or its affiliates, to conduct an independent investigation to address certain issues raised by the blog post. On February 9, 2017, the Special Committee announced that WilmerHale’s inquiry did not find any violation of law. In addition, contrary to the claims in the blog post, the inquiry did not find evidence that the individual who pled guilty to securities fraud unrelated to the Company has had any direct or indirect control or undue influence over the Company. Furthermore, the inquiry did not find evidence establishing that any loan, related party transaction, or any other circumstance impaired the independence of any director. These conclusions were consistent with the preliminary findings announced by the Special Committee on January 23, 2017. The Special Committee also determined that a press release issued on October 18, 2016 contained inaccurate statements. In that press release, the Company stated that the “Board of Directors, acting through its Disinterested Directors” had, as of October 18, 2016, investigated issues raised in the blog post. This press release was inaccurate in certain respects. The review established that although an investigation had been conducted, it was not initiated by the Board of Directors; rather, it appears to have been directed by the Company's management and not by any subset of independent directors. In addition, the press release characterized the investigation as “independent” without disclosing that the law firm conducting the investigation had previously represented both the Company and the Company’s former chief executive officer individually. Furthermore, the press release stated that the Board or a group of “Disinterested Directors” had received “regular reports including related to regulatory and governmental communications.” This overstated both the degree to which the Company had been in contact with regulatory agencies about the subject matter referenced in the blog post, as well as the involvement of the directors in oversight or direction of the inquiry. Related Regulatory Developments. Related to this matter, on January 12, 2017, the Company received a formal order of investigation issued by the SEC directed at certain of the issues that the Special Committee reviewed. The Company has been fully cooperating with the SEC in this investigation. The Company was not able to timely file its 10-Q for the quarter ended September 30, 2016. This led to issuance by the NYSE of a letter notifying the Company that it was not in compliance with the continued listing requirements of Section 802.01E of the NYSE Listed Company Manual. The Company believes that, as of March 1, 2017, it had filed with the SEC all required periodic reports and was no longer out of compliance with the NYSE continued listing standards. The Company anticipates confirming its compliance with NYSE staff in the near future. Changes in Corporate Leadership and Composition of the Board of Directors. On January 23, 2017, the Company announced that Steven A. Sugarman, its President and Chief Executive Officer, had resigned from all positions with the Company and the Bank. The Board appointed Hugh Boyle as Interim Chief Executive Officer and J. Francisco A. Turner as Interim President and Chief Financial Officer. The Board of Directors is currently conducting a search for a new Chief Executive Officer; both internal and external candidates will be considered. In connection with his resignation, on January 23, 2017 (Effective Date), the Company and Mr. Sugarman entered into an Employment Separation Agreement and Release effective as of the Effective Date (Agreement). Under the terms of the Agreement, as negotiated between the Company and Mr. Sugarman, Mr. Sugarman resigned from all positions he held with respect to the Company, the Bank and their respective affiliated entities (collectively, the Bank Affiliated Entities), and resigned from the Board of Directors of the Company and the Bank. The Agreement provides that the Company will pay or provide to Mr. Sugarman (a) his 2016 annual bonus in the amount of $1,500,000 , payable on January 31, 2017; (b) a payment of $1,040,000 on January 31, 2017; (c) a payment of $360,000 , payable on the first payroll date after the six month anniversary of the Effective Date; (d) a payment of $1,350,000 , payable in equal installments commencing on the first payroll date following the six months anniversary of the Effective Date and continuing through the twelfth month following the Effective Date; (e) medical and dental benefits to Mr. Sugarman and his eligible dependents, as if he were an employee, for three years following the Effective Date; and (f) any other amounts or benefits required to be paid or provided or which Mr. Sugarman has a right to receive under any plan, program, policy, practice or contract of the Bank Affiliated Entities through the Effective Date. In addition, Mr. Sugarman’s outstanding unvested equity awards will vest and his options and stock appreciation rights will remain exercisable for their full terms. Mr. Sugarman is not entitled to any other severance payments or benefits. The Agreement contains mutual general releases of claims arising out of acts or omissions occurring on or before the Effective Date, with customary exceptions for obligations arising from the Agreement, vested benefits, indemnity rights and matters that cannot be released by private agreement. Mr. Sugarman agrees to cooperate in providing information for operational, financial and other reports relating to the period of his employment and agrees to remain bound by the clawback and confidentiality provisions of his Amended and Restated Employment Agreement. The Agreement contains a provision for a Standstill Period from the Effective Date through July 1, 2018, during which Mr. Sugarman agrees to limit his ownership of Company shares, his efforts to influence its Board and his efforts to acquire control of the Company. On February 7, 2017, Richard Lashley was appointed to the Boards of Directors of the Company and the Bank, which appointments became effective February 16, 2017. Mr. Lashley was appointed as a Class I director of the Company, whose term will expire at the Company’s 2019 Annual Meeting of Stockholders, in order to fill the vacancy in that class created by Mr. Sugarman’s resignation. Mr. Lashley is a co-founder of PL Capital Advisors, LLC (PL Capital Advisors). PL Capital Advisors and certain affiliates of PL Capital Advisors, including Mr. Lashley (collectively, the PL Capital Group), beneficially own approximately 6.9 percent of the Company’s voting common shares. In connection with the appointment of Mr. Lashley to the Boards, the PL Capital Group has entered into a Cooperation Agreement with the Company, in which the PL Capital Group agreed, among other matters, for a period of time commencing from the date of the Cooperation Agreement through the first day following the Company’s 2017 annual meeting of stockholders, to vote their shares of Company stock (i) in favor of the Company’s slate of directors, (ii) against any stockholder’s nominations for directors not approved and recommended by the Company's Board and against any proposals or resolutions to remove any director and (iii) in accordance with the recommendations by the Company's Board on all other proposals of the Company's Board set forth in the Company’s proxy statement. In addition, during the same period, the PL Capital Group has agreed not to acquire additional shares of the Company that would result in the PL Capital Group having ownership or voting interest in 10 percent or more of the Company’s outstanding voting common shares; not to engage in proxy solicitations in an election contest; not to subject any shares to any voting arrangements except as expressly provided in the Cooperation Agreement; not to make or be a proponent of a stockholder proposal; not to seek or call a meeting of stockholders or solicit consents from stockholders; not to seek to obtain representation on the Company's Board, except as otherwise expressly provided in the Cooperation Agreement; not to seek to remove any director from the Company's Board; not to seek to amend any provision of the governing documents of the Company, or propose or participate in certain extraordinary corporate transactions involving the Company. Pursuant to the Cooperation Agreement, the Company reimbursed the PL Capital Group $150,000 for its legal fees and expenses incurred in connection with its investment in the Company. On February 9, 2017, Chad T. Brownstein retired from the Company’s Board of Directors and, concurrently therewith, entered into an agreement and release (Retirement Agreement), which also provided that the outstanding unvested equity awards held by Mr. Brownstein vested in full. On that same date, the Board of Directors appointed W. Kirk Wycoff to the Boards of Directors of the Company and the Bank, which appointments became effective February 16, 2017. Mr. Wycoff was appointed as a Class III director of the Company, whose term will expire at the Company’s 2018 Annual Meeting of Stockholders, in order to fill the vacancy in that class created by the retirement of Mr. Brownstein. Mr. Wycoff is a managing partner of Patriot Financial Partners, which beneficially owns approximately 6.2 percent of the Company’s voting common shares. For additional information regarding Patriot, see Note 26. Changes in Corporate Governance. The Company disclosed on January 23, 2017 certain changes to its Board leadership structure and corporate governance policies. Such changes included separation of the roles of Chief Executive Officer and Chair of the Board and elimination of the Board’s Executive Committee. Robert Sznewajs, an independent director, was appointed Chair of the Board. In light of the separation of the Chair and Chief Executive Officer positions, the Board also eliminated the positions of Lead Independent Director (a role which will be filled by the Chair of the Board) and Vice-Chair of the Board (a role which will be filled by the Chair of the Joint Nominating and Corporate Governance Committee.) In addition to the changes in Board leadership, the Board of Directors has undertaken a review of its corporate governance practices. On January 23, 2017, the Company announced the separation of the Joint Compensation and Corporate Governance Committee into two separate committees, one focusing on compensation matters and one focusing on governance matters. On January 29, 2017, the Board approved a revised policy on related party transactions intended to limit such transactions and to implement a process requiring rigorous review prior to any approval. On February 7, 2017 the Board of Directors approved a policy limiting outside business activities by officers and employees and requiring non-employee directors to avoid outside business activities which would create a conflict of interest or appearance of such a conflict. The Board is continuing its review of governance issues and may implement additional changes to the Company's corporate governance policies. Cessation of CS Financial, Inc. Operations The Bank purchased CS Financial in 2013 and has operated it as a wholly owned subsidiary. Currently, the Bank does not maintain any employees or offices and has discontinued taking new loan applications for CS Financial. The Bank will be ceasing the operations of CS Financial. Los Angeles Football Club Naming Rights and Sponsorship On February 28, 2017, the Bank executed more detailed definitive agreements with Los Angeles Football Club and LAFC Stadium Co. LLC with respect to naming rights and sponsorship, which are subject to MLS rules and/or approval, all as more fully described in Note 26. Sale of Mortgage Banking Segment and MSRs On February 28, 2017, the Bank entered into a definitive asset purchase agreement (the Agreement) with Caliber Home Loans, Inc., a Delaware corporation (the Purchaser), pursuant to which the Bank has agreed to sell and the Purchaser has agreed to purchase specified assets of its Mortgage Banking segment, operated under the trade name of Banc Home Loans, which relate to the Bank’s business of originating, processing, underwriting, funding and selling residential mortgage loans (the Business). The assets to be acquired by the Purchaser include, among other things, the leases relating to the Bank’s dedicated mortgage loan origination offices and the Bank’s pipeline of residential mortgage loan applications for loans. The Purchaser has agreed to assume certain obligations and liabilities of the Bank under the acquired leases and certain other specified assigned contracts, and with respect to the employment of transferred employees. Pursuant to the Agreement and subject to the terms and conditions contained therein, the Bank will receive a $25.0 million cash premium payment, in addition to the net book value of certain assets acquired by the Purchaser, totaling $2.7 million upon closing of the transaction. The Bank may receive up to an additional $5.0 million cash premium based on criteria tied to loan officer retention by the Purchaser. Additionally, the Bank will receive an earn-out, payable quarterly, based on the future performance of the Business over the 38 months following completion of the transaction. The Purchaser retains an option to buyout the future earn-out payable to the Bank 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 the Purchaser makes the payment of the buyout amount. The transaction, which is expected to close on March 30, 2017, is subject customary conditions to closing, including the accuracy of customary representations and warranties of, the Bank and the Purchaser. The Bank also entered into a separate agreement with the Purchaser for the sale of mortgage servicing rights (MSRs) on approximately $3.8 billion in unpaid balances of conventional agency mortgages to the Purchaser. The Purchaser will purchase the MSRs for $36 million , resulting in a net loss of $3.5 million as a result of the MSR sale. This sale of approximately half the Bank’s MSR portfolio is expected to reduce earnings volatility going forward. Management has evaluated subsequent events through the date of issuance of the financial data included herein. Other than the events discussed above, there have been no subsequent events occurred during such period that would require disclosure in this report or would be required to be recognized in the Consolidated Financial Statements as of December 31, 2016 .

SUMMARY OF SIGNIFICANT ACCOUN37

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The consolidated financial statements include the accounts of the Company and all other entities in which it has a controlling financial interest. All significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiaries. The accounting and reporting polices of the Company are based upon GAAP and conform to predominant practices within the financial services industry. Significant accounting policies followed by the Company are presented below. Certain prior period amounts have been reclassified to conform to the current year's presentation. These reclassifications had no impact on the Company's consolidated financial condition, results of operations or net change in cash or cash equivalents.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and disclosures provided, and actual results could differ. The allowance for loan and lease losses, reserve for loss on repurchased loans, servicing rights, realization of deferred tax assets, the valuation of goodwill and other intangible assets, mortgage banking derivatives, purchased credit impaired loan discount accretion, fair value of assets and liabilities acquired in business combinations, and the fair value measurement of financial instruments are particularly subject to change and such change could have a material effect on the consolidated financial statements.
Cash and cash equivalents	Cash and cash equivalents: Cash and cash equivalents include cash on hand, interest-bearing deposits with other financial institutions with original maturities under 90 days, and daily federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing deposits in other financial institutions, and federal funds purchased, including overnight borrowings with the FHLB. Cash flows from loans, either originated or acquired, are classified at that time according to management's original intent to either sell or hold the loan for the foreseeable future. When management's intent at origination or purchase is to sell the loan, the cash flows of that loan are presented as operating cash flows. When management's intent is to hold the loan for the foreseeable future, the cash flows of that loan are presented as investing cash flows.
Time Deposits in Financial Institutions	Time Deposits in Financial Institutions: Time deposits in financial institutions have original maturities over 90 days and are carried at cost.
Investment Securities	Investment Securities: Investment securities are classified at the time of purchase as available-for-sale or held-to-maturity. The Company presently has no investment securities classified as held-for-trading. Debt securities classified as held-to-maturity are recorded at amortized cost when management has the positive intent and ability to hold them to maturity. Debt securities are classified as available-for-sale when management intends that they might be sold before maturity. Equity securities with readily determinable fair values are classified as available-for-sale. Securities available-for-sale are carried at fair value with unrealized holding gains and losses. Unrealized holding gains and losses, net of taxes, are reported in AOCI on the Consolidated Statements of Financial Condition. Accreted discounts and amortized premiums are included in interest income using the level yield method, and realized gains or losses from sales of securities are calculated using the specific identification method. Management evaluates securities for OTTI at least on a quarterly basis, and more frequently when economic conditions warrant such an evaluation. Investment securities classified as available-for-sale or held-to-maturity are generally evaluated for OTTI under ASC 320, Accounting for Certain Investments in Debt and Equity Securities. However, certain purchased beneficial interests, including non-agency mortgage-backed securities, asset-backed securities, collateralized debt obligations, and collateralized loan obligations, that had credit ratings at the time of purchase of below AA are evaluated using the model outlined in ASC 325, Recognition of Interest Income and Impairment on Purchased Beneficial Interests and Beneficial Interests that Continue to be Held by a Transfer in Securitized Financial Assets. In determining OTTI under the ASC 320 model, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also considers whether the market decline was affected by macroeconomic conditions, and assesses whether the Company intends to sell, or it is more likely than not it will be required to sell a security in an unrealized loss position before recovery of its amortized cost basis. The assessment of whether OTTI exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. The second segment of the portfolio uses the OTTI guidance provided by ASC 325 that is specific to purchased beneficial interests that, on the purchase date, were rated below AA. Under the ASC 325 model, the Company compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows. When OTTI occurs in either model, the amount of the impairment recognized in earnings depends on the Company’s intent to sell the security or if it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (i) OTTI related to credit loss, which must be recognized in the income statement and (ii) other-than-temporary impairment related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities the entire amount of impairment is recognized through earnings.
Federal Home Loan Bank (FHLB) and Federal Reserve Bank (FRB) Stock	Federal Home Loan Bank and Federal Reserve Bank Stock: The Bank is a member of the FHLB and FRB system. Members are required to own a certain amount of FHLB and FRB stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB and FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported in Dividends and Other Interest-earning Assets Interest Income on the Consolidated Statements of Operations.
Loans Held for Sale	Conforming SFR Mortgage Loans Held-for-Sale: Conforming SFR mortgage loans originated and intended for sale in the secondary market are carried at the fair value as of each balance sheet date, as determined by outstanding commitments from investors or what secondary markets are currently offering for portfolios with similar characteristics. The fair value includes the servicing value of the loans as well as any accrued interest. Conforming SFR mortgage loans held-for-sale are generally sold with servicing rights retained or sold through a flow agreement (See Note 7 for additional information). Origination fees and costs are recognized in earnings at the time of origination for newly originated loans held-for-sale. Gains and losses on sales of conforming SFR mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. The Company’s conforming SFR mortgage loans held-for-sale at fair value were GSE or Government-eligible at December 31, 2016 . These loans are considered to have reliable market price information and the fair value of these loans was based on quoted market prices of similar assets and included the value of loan servicing. In scenarios of market disruptions, the current secondary market prices that are generally relied on to value GSE or Government-eligible mortgage loans may not be readily available. In these circumstances, the Company may consider other factors, including: (i) quoted market prices for to-be-announced securities (for agency-eligible loans); (ii) recent transaction settlements or trades but unsettled transactions for similar assets; (iii) recent third party market transactions for similar assets; and (iv) modeled valuations using assumptions that the Bank believes would be used by market participants in estimating fair value (assumptions may include prepayment rates, interest rates, volatilities, mortgage spreads and projected loss rates). Adjustments to reflect unrealized gains and losses resulting from changes in fair value and realized gains and losses upon ultimate sale of the loans are classified as part of Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations. Non-Conforming SFR Mortgage Loans Held-for-Sale: Non-conforming SFR mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value on an aggregate basis. A decline in the aggregate fair value of the loans below their aggregate carrying amount is recognized through a charge to earnings in the period of such a decline. Unearned income on the loans is taken into earnings when they are sold. Gains and losses on sales of non-conforming SFR mortgage loans are included in Net Gain on Sale of Loans on the Consolidated Statements of Operations. SBA Loans Held-for-Sale: SBA loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated market value in the aggregate. Net unrealized losses are recognized through a valuation allowance by charges to income. Gains or losses realized on the sales of SBA loans are recognized at the time of sale and are determined by the difference between the net sales proceeds and the carrying value of the loans sold, adjusted for any servicing asset or liability. Gains and losses on sales of SBA loans are included in Net Gain on Sale of Loans on the Consolidated Statements of Operations.
Loan and Leases	Loans and Leases: Loans and leases, other than PCI loans, that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff are recorded at the principal balance outstanding, net of charge-offs, unamortized purchase premiums and discounts, and deferred loan fees and costs. The deferred loan fees and costs, and purchase premiums and discounts are recognized in interest income as an adjustment to yield over the term of loans and leases using the effective interest method. Interest on loans and leases is credited to interest income as earned based on the interest rate applied to principal amounts outstanding. Interest income is accrued on the unpaid principal balance and is discontinued when management believes, after considering economic and business conditions and collection efforts, that the borrower’s financial condition is such that full collection of principal or interest becomes doubtful, regardless of the length of past due status. Generally loans and leases are placed on nonaccrual status when their payments are past due for 90 days or more. When interest accrual is discontinued, all unpaid accrued interest is reversed against interest income. Interest received on such loans and leases is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. A charge-off is generally recorded at 180 days past due if the unpaid principal balance exceeds the fair value of the collateral less costs to sell. Commercial and industrial and commercial real estate loans and equipment finance leases are subject to a detailed review when 90 days past due to determine accrual status, or when payment is uncertain and a specific consideration is made to put a loan or lease on non-accrual status. Consumer loans, other than those secured by real estate, are typically charged off no later than 180 days past due. Loans and leases are returned to accrual status when the borrower has demonstrated a satisfactory payment trend subject to management’s assessment of the borrower’s ability to repay the loan or lease.
Allowance for Loan and Lease Losses	Allowance for Loan and Lease Losses: The ALLL is a reserve established through a provision for loan and lease loses charged to expense, and represents management’s best estimate of probable losses that may be incurred within the existing loan and lease portfolio as of the date of the consolidated financial statements. Subsequent recoveries, if any, are credited to the ALLL. The Company performs an analysis of the adequacy of the ALLL at least on a quarterly basis. Management estimates the ALLL balance required using past loan and lease loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. The ALLL consists of three elements; (i) specific valuation allowances established for probable losses on impaired loans and leases, (ii) quantitative valuation allowances calculated using loss experience for loans and leases with similar characteristics and trends, adjusted as necessary to reflect the impact of current conditions; and (iii) qualitative allowances determined based on environmental and other factors that may be internal or external to the Company. A loan or lease is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan or lease agreement. The Company evaluates all impaired loans and leases individually under the guidance of ASC 310, Receivables, primarily through the evaluation of collateral values and estimated cash flows. Loans for which the terms have been modified by granting a concession that normally would not be provided and where the borrower is experiencing financial difficulties are considered TDRs and classified as impaired. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. The impairment amount on a collateral dependent loan is charged-off to the ALLL and the impairment amount on a loan that is not collateral dependent is set-up as a specific reserve. TDRs are also measured at the present value of estimated future cash flows using the loan’s effective rate at inception or at the fair value of collateral, less costs to sell, if repayment is expected solely from the collateral. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the ALLL. At December 31, 2016 , the following loan and lease portfolio segments have been identified: • Commercial and industrial (secured, unsecured, securities-backed lines of credit, warehouse lending, and leveraged lending) • Commercial real estate (retail, office, industrial, hospitality, and other) • Multi-family • SBA • Construction • Leases • SFR - 1st deeds of trust (amortizing, interest only now amortizing, interest only, negative amortizing, and Green Loans) • Other consumer (SFR, including HELOC - 2nd deeds of trust and other) The Company categorizes loans and leases into risk categories based on relevant information about the ability of borrowers and lessees (also referred to as borrowers) to service their obligations such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. 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. Classification of problem SFR mortgage loans is performed on a monthly basis while analysis of non-homogeneous loans is performed on a quarterly basis. Loans secured by multi-family and commercial real estate properties generally involve a greater degree of credit risk than SFR mortgage loans. Because payments on loans secured by multi-family and commercial real estate properties are often dependent on the successful operation or management of the properties, repayment of these loans may be subject to adverse conditions in the real estate market or the economy. Commercial business loans are also considered to have a greater degree of credit risk than SFR mortgage loans due to the fact commercial business loans are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment of commercial business loans may be substantially dependent on the success of the business itself (which, in turn, is often dependent in part upon general economic conditions). SBA loans are similar to commercial business loans, but have additional credit enhancement provided by the U.S. Small Business Administration, for up to 85 percent of the loan amount for loans up to $150 thousand and 75 percent of the loan amount for loans of more than $150 thousand. Commercial equipment leases are also similar to commercial business loans in that the leases are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. As a result, the availability of funds for the repayment of commercial equipment leases may be substantially dependent on the success of the business itself (which, in turn, is often dependent in part upon general economic conditions). Consumer and other real estate loans may entail greater risk than do SFR mortgage loans given that collection of these loans is dependent on the borrower’s continuing financial stability and, thus, are more likely to be adversely affected by job loss, divorce, illness, or personal bankruptcy. Green Loans are also considered to carry a higher degree of credit risk due to their unique cash flows. Credit risk on this asset class is also managed through the completion of regular re-appraisals of the underlying collateral and monitoring of the borrower’s usage of this account to determine if the borrower is making monthly payments from external sources or “drawdowns” on their line. In cases where the property values have declined to levels less than the original LTV ratios, or other levels deemed prudent by the Company, the Company may curtail the line and/or require monthly payments or principal reductions to bring the loan in balance. Classified Assets: Federal regulations provide for the classification of loans, leases, and other assets, such as debt and equity securities considered to be of lesser quality, as “substandard,” “doubtful” or “loss.” An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. “Substandard” assets include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses inherent in those classified “substandard,” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions, and values, “highly questionable and improbable.” Assets classified as “loss” are those considered “uncollectible” and of such little value that their continuance as assets without the establishment of a specific loss reserve is not warranted. When an insured institution classifies problem assets as “loss,” it is required to charge off such amount. The Bank’s determination as to the classification of its assets and the amount of its valuation allowances is subject to review by its primary regulator, which may order the establishment of additional general or specific loss allowances.
Troubled Debt Restructurings (TDR)	Troubled Debt Restructurings: A loan is identified as a TDR when a borrower is experiencing financial difficulties and for economic or legal reasons related to these difficulties, the Company grants a concession to the borrower in the restructuring that it would not otherwise consider. The Company has granted a concession when, as a result of the restructuring to a troubled borrower, it does not expect to collect all amounts due, including principal and/or interest accrued at the original terms of the loan. The concessions may be granted in various forms, including a below-market change in the stated interest rate, a reduction in the loan balance or accrued interest, an extension of the maturity date, or a note split with principal forgiveness. Loans for which the borrower has been discharged under Chapter 7 bankruptcy are considered collateral dependent TDRs, impaired at the date of discharge, and charged down to the fair value of collateral less cost to sell. A restructuring executed at an interest rate that is at market interest rates based on the current credit characteristics of the borrower is not a TDR. The Company’s policy is to place consumer loan TDRs, except those that were performing prior to TDR status, on non-accrual status for a minimum period of 6 months . Commercial TDRs are evaluated on a case-by-case basis for determination of whether or not to place on non-accrual status. Loans qualify for return to accrual status once they have demonstrated performance with the restructured terms of the loan agreement for a minimum of 6 months. Initially, all TDRs are reported as impaired. Generally, TDRs are classified as impaired loans and reported as TDRs for the remaining life of the loan. Impaired and TDR classification may be removed if the borrower demonstrates compliance with the modified terms for a minimum of 6 months and through one fiscal year-end and the restructuring agreement specifies a market rate of interest equal to that which would be provided to a borrower with similar credit at the time of restructuring. In the limited circumstance that a loan is removed from TDR classification, it is the Company’s policy to continue to base its measure of loan impairment on the contractual terms specified by the loan agreement.
Purchased Credit-Impaired Loans	Purchased Credit-Impaired Loans: The Company purchases loans with and without evidence of credit quality deterioration since origination. Evidence of credit quality deterioration as of the purchase date may include statistics such as prior loan modification history, updated borrower credit scores and updated LTV ratios, some of which may not be immediately available as of the purchase date. Purchased loans with evidence of credit quality deterioration where the Company estimates that it will not receive all contractual payments are accounted for as PCI loans. The excess of the cash flows expected to be collected on PCI loans, measured as of the acquisition date, over the estimated fair value is referred to as the accretable yield and is recognized in interest income over the remaining life of the loan or lease using a level yield methodology. The difference between contractually required payments as of the acquisition date and the cash flows expected to be collected is referred to as the non-accretable difference. PCI loans that have similar risk characteristics, primarily credit risk, collateral type and interest rate risk, are pooled and accounted for as a single unit with a single composite interest rate and an aggregate expectation of cash flows. Loans that were acquired during the year ended December 31, 2012 in connection with the Beach Business Bank and Gateway Bancorp acquisitions and during the year ended December 31, 2013 in connection with the The Private Bank of California acquisition that were considered credit impaired were recorded at fair value at the acquisition date and the related ALLL was not carried over to the Company’s ALLL. In addition, the Company acquired one PCI seasoned SFR mortgage loan pool during the year ended December 31, 2016, seven pools of seasoned SFR mortgage loans, which were partially PCI loans, during the year ended December 31, 2015, five pools of seasoned SFR mortgage loans, which were partially PCI loans, during the year ended December 31, 2013, and three pools of PCI seasoned SFR mortgage loans during the year ended December 31, 2012. Any losses on such loans are charged against the non-accretable difference established in purchase accounting and are not reported as charge-offs until such non-accretable difference is fully utilized. These loans were evaluated individually and were not part of the aforementioned pools. The Company estimates cash flows expected to be collected over the life of the loan using management’s best estimate which is derived using current key assumptions such as default rates, loss severity and payment speeds. If, upon subsequent evaluation, the Company determines it is probable that the present value of the expected cash flows have decreased due to a deterioration of credit, the PCI loan is considered further impaired which will result in a charge to the provision for loan and lease losses and a corresponding increase to the ALLL. If, upon subsequent evaluation, it is probable that there is an increase in the present value of the expected cash flows, the Company will reduce any remaining allowance. If there is no remaining allowance, the Company will recalculate the amount of accretable yield as the excess of the revised expected cash flows over the current carrying value resulting in a reclassification from non-accretable difference to accretable yield. The present value of the expected cash flows for PCI purchased loan pools is determined using the PCI loans’ effective interest rate, adjusted for changes in the PCI loans’ interest rate indexes. Adjustments in interest rate assumptions and prepayment behavior do not impact the Company’s assessment of credit impairment. The present value of the expected cash flows for PCI loans acquired through mergers with other banks includes, in addition to the above, an evaluation of the creditworthiness of the borrower. Loan dispositions may include sales of loans, receipt of payments in full from the borrower or foreclosure. Write-downs are not recorded on the PCI loan pool until actual losses exceed the remaining non-accretable difference. To date, no write-downs have been recorded for the PCI loans held by the Company.
Other Real Estate Owned	Other Real Estate Owned: OREO, which represents real estate acquired through foreclosure in satisfaction of commercial and real estate loans, is initially recorded at fair value less estimated selling costs of the real estate, based on current independent appraisals obtained at the time of acquisition, less costs to sell when acquired, establishing a new cost basis. Loan balances in excess of fair value of the real estate acquired at the date of acquisition are charged to the ALLL. Gains and losses on the sale of OREO are included in Net Gain on Sales of Other Real Estate Owned, reductions in fair value subsequent to foreclosure are included in Valuation Allowance for Other Real Estate Owned and any subsequent operating expenses or income of such properties are included in All Other Expense on the Consolidated Statements of Operations.
Premises, Equipment, and Capital Leases	Premises, Equipment, and Capital Leases: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method with the following estimated useful lives: building - 40 years and leasehold improvements - life of lease, and furniture, fixtures, and equipment - 3 to 7 years . Maintenance and repairs are charged to expense as incurred, and improvements that extend the useful lives of assets are capitalized.
Bank Owned Life Insurance	Bank Owned Life Insurance: The Bank has purchased life insurance policies on certain key current and former executives. BOLI is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Servicing Rights - Mortgage (Carried at Fair Value) and Servicing Rights - SBA (Carried at Lower of Cost or Fair Value)	Servicing Rights - Mortgage (Carried at Fair Value): A servicing asset or liability is recognized when undertaking an obligation to service a financial asset under a mortgage servicing contract, including a transfer of the servicer’s financial assets that meet the requirements for sale accounting. Such servicing asset or liability is initially measured at fair value based on either market prices for comparable servicing contracts or alternatively is based on a valuation model that is based on the present value of the contractually specified servicing fee, net of servicing costs, over the estimated life of the loan, using a discount rate based on the related note rate and is recorded on the Consolidated Statements of Operations. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. Under the fair value measurement method, the Company measures servicing rights at fair value at each reporting date and reports changes in fair value of servicing assets in earnings in the period in which the changes occur, and are included with Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimates and actual prepayment speeds and default rates and losses. Currently the Company does not hedge the income statement effects of changes in fair value of the servicing assets. Servicing fee income, which is reported in Loan Servicing Income on the Consolidated Statements of Operations, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal; or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees related to loan servicing are not material. Servicing Rights - SBA Loans (Carried at Lower of Cost or Fair Value): As a general course of business, the Bank originates and sells the guaranteed portion of its SBA loans. To calculate the gain (loss) on sales of SBA loans, the Bank’s investment in the loan is allocated among the retained portion of the loan, the servicing retained, the interest-only strip and the sold portion of the loan, based on the relative fair market value of each portion. The gain (loss) on the sold portion of the loan is recognized at the time of sale based on the difference between sale proceeds and the amount of the allocated investment to the sold portion of the loan. The portion of the servicing fees that represent contractually specified servicing fees (contractual servicing) is reflected as a servicing asset and is amortized over the estimated life of the servicing; in the event future prepayments exceed management’s estimates and future expected cash flows are inadequate to cover the servicing asset, impairment is recognized. The portion of servicing fees in excess of contractual servicing fees are reflected as interest-only (I/O) strips receivable, which is included in Other Assets on the Consolidated Statements of Financial Condition. The I/O strips receivable are carried at fair value, with unrealized gains and losses recorded in the Consolidated Statements of Operations.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets: Goodwill represents the excess purchase price of businesses acquired over the fair value of the identifiable net assets acquired and is assigned to specific reporting units. Goodwill is not subject to amortization and is evaluated for impairment annually, during the third fiscal quarter, or more frequently in the interim if events occur or circumstances change indicating it would more likely than not result in a reduction of the fair value of a reporting unit below its carrying value. Goodwill is evaluated for impairment by either performing a qualitative evaluation or a two-step quantitative test. The qualitative evaluation is an assessment of factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. Discounted cash flow estimates, which include significant management assumptions relating to revenue growth rates, net interest margins, weighted average cost of capital, and future economic and market conditions, are used to determine fair value under the two-step quantitative test. In Step 1, the fair value of a reporting unit is compared to its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired, and it is not necessary to continue to Step 2 of the impairment process. Otherwise, Step 2 is performed where the implied fair value of goodwill is compared to the carrying value of goodwill in the reporting unit. If a reporting unit's carrying value exceeds fair value, the difference is charged to noninterest expense. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights, or because the asset is capable of being sold or exchanged either separately or in combination with a related contract, asset or liability. Other intangible assets with finite useful lives are amortized to noninterest expense over their estimated useful lives and are evaluated for impairment whenever events occur or circumstances change indicating the carrying amount of the asset may not be recoverable.
Affordable Housing Fund Investment	Affordable Housing Fund Investment: The Company has invested in four limited partnerships that were formed to develop and operate several apartment complexes designed as high-quality affordable housing for lower income tenants throughout the State of California and other states. The Company accounts for these investments under the proportional amortization method. The Company’s ownership in each limited partnership varies from 8 percent to 14 percent . At December 31, 2016 and 2015 , the gross investments in these limited partnerships amounted to $29.1 million and $9.2 million , respectively, with the original committed investment amounts to be $29.5 million and $9.5 million , respectively. The unfunded portion was $335 thousand at December 31, 2016 . Each of the partnerships must meet the regulatory minimum requirements for affordable housing for a minimum 15 -year compliance period to fully utilize the tax credits. If the partnerships cease to qualify during the compliance period, the credit may be denied for any period in which the project is not in compliance and a portion of the credit previously taken is subject to recapture with interest.
Reserve for Unfunded Commitments	Reserve for Unfunded Commitments: The reserve for unfunded commitments provides for probable losses inherent with funding the unused portion of legal commitments to available to lend. The unfunded reserve calculation includes factors that are consistent with ALLL methodology for funded loans using the expected loss factors and a draw down factor applied to the underlying borrower risk and facility grades. Changes in the reserve for unfunded credit commitments, within Accrued Expenses and Other Liabilities, is reported as a component of All Other Expense on the Consolidated Statements of Operations.
Reserve for Loss on Repurchase Loans	Reserve for Loss on Repurchased Loans: In the ordinary course of business, as loans held-for-sale are sold, the Bank makes standard industry representations and warranties about the loans. The Bank may have to subsequently repurchase certain loans or reimburse certain investor losses due to defects that may have occurred in the origination of the loans. Such defects include documentation or underwriting errors. In addition, certain investor contracts require the Bank to repurchase loans from previous whole loan sales transactions that experience early payment defaults. If there are no such defects or early payment defaults, the Bank has no commitment to repurchase loans that it has sold. In addition, we have the option to buy out severely delinquent loans at par from Ginnie Mae pools for which we are the servicer and issuer of the pool. The level of reserve for loss on repurchased loans is an estimate that requires considerable management judgment. The Bank’s reserve is based upon the expected future repurchase trends for loans already sold in whole loan sale transactions and the expected valuation of such loans when repurchased, which include first and second trust deed loans. At the point when loss reimbursements are made directly to the investor, the reserve for loss reimbursements on sold loans is charged for the losses incurred.
Business Combinations	Business Combinations: Business combinations are accounted for under the acquisition method of accounting in accordance with ASC 805, Business Combinations. Under the acquisition method the acquiring entity in a business combination recognizes 100 percent of the acquired assets and assumed liabilities, regardless of the percentage owned, at their estimated fair values as of the date of acquisition. Any excess of the purchase price over the fair value of net assets and other identifiable intangible assets acquired is recorded as goodwill. To the extent the fair value of net assets acquired, including other identifiable assets, exceed the purchase price, a bargain purchase gain is recognized. Assets acquired and liabilities assumed from contingencies must also be recognized at fair value, if the fair value can be determined during the measurement period. Results of operations of an acquired business are included in the statement of operations from the date of acquisition. Acquisition-related costs, including conversion and restructuring charges, are expensed as incurred.
Long-term Assets	Long-Term Assets: Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
Deferred Financing Costs	Deferred Financing Costs: Deferred financing costs associated with the Company’s senior notes and junior subordinated amortizing notes are included in Notes Payable on the Consolidated Statements of Financial Condition. The deferred financing costs are being amortized on a basis that approximates a level yield method over the 8 year term of the senior notes and the 5 year term of the junior subordinated amortizing notes.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments: Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Stock-Based Compensation	Stock-Based Compensation: Compensation cost is recognized for stock appreciation rights, stock options and restricted stock awards issued to employees and directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options and stock appreciation rights, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.
Income Taxes	The Company and its subsidiaries are subject to U.S. Federal income tax as well as income tax in multiple state jurisdictions. The Company is no longer subject to examination by U.S. Federal taxing authorities for years before 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. Tax positions that are uncertain but meet a more likely than not recognition threshold are initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position meets the more likely than not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management's judgment. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. 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 bases 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 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 its involvement with the VIE. The Company performs analyses of whether the Company is the primary beneficiary of 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 this partnership, which was formed to invest in newly installed residential rooftop solar leases and power purchase agreements. The Company uses the flow-through income statement method to account for the tax credits earned on investments in alternative energy partnership. 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. 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.
Earnings Per Common Share	Earnings Per Common Share: Earnings per common share is computed under the two-class method. Basic EPS is computed by dividing net income allocated to common stockholders by the weighted average number of shares outstanding, including the minimum number of shares issuable under purchase contracts relating to the tangible equity units (see the discussion of the tangible equity units in Note 18). 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. Net income allocated to common stockholders is computed by subtracting income allocated to participating securities, participating securities dividends and preferred stock dividend from net income. Participating securities are instruments granted in share-based payment transactions that contain rights to receive non-forfeitable 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 16.
Comprehensive Income (Loss)	Comprehensive Income (Loss): Comprehensive income (loss) consists of net income (loss) and other comprehensive income or loss. Other comprehensive income or loss includes unrealized gains and losses on securities available-for-sale and interest rate swap, net of tax, which are recognized as a separate component of stockholders’ equity.
Accounting for Derivative Instruments and Hedging Activities	Accounting for Derivative Instruments and Hedging Activities: The Company records its derivative instruments at fair value as either assets or liabilities on the Consolidated Statements of Financial Condition in Other Assets and Accrued Expenses and Other Liabilities, respectively, and has elected to present all derivatives with counterparties on a gross basis. For hedged derivatives, the Company records changes in fair value in AOCI in the Consolidated Statements of Financial Condition and records any hedge ineffectiveness in Other Income in the Consolidated Statements of Operations. For non-hedged derivatives, the Company records changes in fair value in Net Revenue on Mortgage Banking Activities or Other Income in the Consolidated Statements of Operations. Derivative Instruments Related to Mortgage Banking Activities. The Company enters into commitments to originate mortgage loans whereby the interest rate on the loan is set prior to funding (interest rate lock commitments, or IRLCs). The Company hedges the risk of the overall change in the fair value of loan commitments to borrowers by selling forward contracts on securities of GSEs. The Company has not formally designated these derivatives as a qualifying hedge relationship and accordingly, accounts for such IRLCs and forward contracts as non-hedged derivatives with changes in fair value recorded to earnings each period. The changes in fair value on these instruments are recorded in Net Revenue on Mortgage Banking Activities on the Consolidated Statements of Operations. The estimated fair value is based on current market prices for similar instruments. Interest Rate Swaps and Caps. The Company has entered into pay-fixed, receive-variable interest rate swap contracts with institutional counterparties to hedge against variability in cash flows attributable to interest rate risk caused by changes in the LIBOR benchmark interest rate on the Company’s ongoing LIBOR-based variable rate deposits and other borrowings. The Company also 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. In addition, 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 identical 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 Company accounts for these derivative instruments as non-hedged derivatives with changes in fair value recorded to earnings each period. The changes in fair value on these instruments are recorded in Other Income on the Consolidated Statements of Operations. 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. The changes in fair value on these instruments are recorded in Other Income on the Consolidated Statements of Operations.
Loss Contingencies	Loss Contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are any such matters that will have a material effect on the consolidated financial statements that are not currently accrued for.
Dividend Restriction	Dividend Restriction: Banking regulations require maintaining certain capital levels and may limit the dividends paid by the Bank to the Company or by the Company to stockholders.
Fair Value of Financial Instruments	Fair Values of Financial Instruments: The Company measures certain assets and liabilities on a fair value basis, in accordance with ASC Topic 820, "Fair Value Measurement." Fair value is used on a recurring basis for certain assets and liabilities in which fair value is the primary basis of accounting. Examples of these include derivative instruments and available-for-sale securities. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment in accordance with ASC Topic 825, "Financial Instruments." Examples of these include impaired loans, long-lived assets, OREO, goodwill, and core deposit intangible assets as well as loans held-for-sale accounted for at the lower of cost or fair value. Fair value is the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants. When observable market prices are not available, fair value is estimated using modeling techniques such as discounted cash flow analysis. These modeling techniques utilize assumptions that market participants would use in pricing the asset or the liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset, and the risk of nonperformance. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating the instrument’s fair value. Considerable judgment may be involved in determining the amount that is most representative of fair value. To increase consistency and comparability of fair value measures, ASC Topic 820, "Fair Value Measurement" established a three-level hierarchy to prioritize the inputs used in valuation techniques between observable inputs among (i) observable inputs that reflect quoted prices in active markets, (ii) inputs other than quoted prices with observable market data, and (iii) unobservable data such as the Company’s own data or single dealer non-binding pricing quotes. The Company assesses the valuation hierarchy for each asset or liability measured at the end of each quarter; as a result assets or liabilities may be transferred within hierarchy levels due to changes in availability of observable market inputs to measure fair value at the measurement date.
Transfer of Financial Assets	Transfer of Financial Assets: Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is generally considered to have been surrendered when (i) the transferred assets are legally isolated from the Company or its consolidated affiliates, even in bankruptcy or other receivership, (ii) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee or provide more than a trivial benefit to the Company, and (iii) the Company does not maintain an obligation or the unilateral ability to reclaim or repurchase the assets. The Company sells financial assets in the normal course of business, the majority of which are residential mortgage loan sales primarily to government-sponsored enterprises through established programs and other individual or portfolio loan and securities sales. In accordance with accounting guidance for asset transfers, the Company considers any ongoing involvement with transferred assets in determining whether the assets can be derecognized from the balance sheet. With the exception of servicing and certain performance-based guarantees, the Company’s continuing involvement with financial assets sold is minimal and generally limited to market customary representation and warranty clauses. When the Company sells financial assets, it may retain servicing rights and/or other interests in the financial assets. The gain or loss on sale depends on the previous carrying amount of the transferred financial assets and the consideration received and any liabilities incurred in exchange for the transferred assets. Upon transfer, any servicing assets and other interests held by the Company are carried at the lower of cost or fair value.
Fee Revenue	Fee Revenue: Generally, fee revenue from deposit service charges and loans is recognized when earned, except where ultimate collection is uncertain, in which case revenue is recognized when received.
Marketing Costs	Marketing Costs: Marketing costs are expensed as incurred.
Adopted Accounting Pronouncements and Accounting Pronouncements Not Yet Adopted	Adopted Accounting Pronouncements: During the year ended December 31, 2016, the following pronouncement applicable to the Company was adopted: In June 2014, the FASB issued ASU No. 2014-12, “ Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. ” The ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718 as it relates to awards with performance conditions that affect vesting to account for such awards. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Adoption of the new guidance has not had a significant impact on the Company's consolidated financial statements. Accounting Pronouncements Not Yet Adopted: The following are recently issued accounting pronouncements applicable to the Company that have not yet been adopted: In January 2016, the FASB issued ASU 2016-01, “ Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities .” This Update amends certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The ASU requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; it simplifies the impairment assessment of equity investments by requiring a qualitative assessment; it eliminates the requirement for public business entities to disclose methods and assumptions for financial instruments measured at amortized cost on the statement of financial position; it requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability; it requires separate presentation of financial assets and liabilities by measurement category; and certain other requirements. This ASU becomes effective for interim and annual periods beginning on or after December 15, 2017. Early application of the amendments in this Update is not permitted. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “ Leases (Topic 842) .” The amendments in this Update requires lessees to recognize the assets and liabilities that arise from leases, as well as defines classification criteria for distinguishing between financing leases and operating leases. For financing leases, lessees are required to recognize a right-of-use asset and a lease liability in the statement of financial position, recognize interest on the lease liability in the statement of comprehensive income, and classify the principal portion of the lease liability within financing activities and payments of interest within operating activities in the statement of cash flows. For operating leases, lessees are required to recognize a right-of-use asset and a lease liability in the statement of financial position, recognize a single lease cost calculated so that the cost of the lease is allocated over lease term on a straight line basis, and classify all cash payments as operating activities in the statement of cash flows. Lessor accounting is largely unchanged, but does align the transfer of control principle for a sale in Topic 606 to leases. For example, whether a lease is similar to a sale of the underlying asset depends on whether the lessee, in effect, obtains control of the underlying asset as a result of the lease. 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 March 2016, the FASB issued ASU 2016-08, “ Revenue from Contracts with Customers (Topic 606). ” This Update amends the principal versus agent guidance in ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2016-08 clarifies that the analysis must focus on whether the entity has control of the goods or services before they are transferred to the customer. The amendments in ASU 2016-08 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 currently evaluating the guidance to determine its adoption method and does not expect this guidance to have a material impact on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “ Compensation - Stock Compensation (Topic 718). ” 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. Early adoption is permitted in any interim or annual period provided the entire ASU is adopted. If an entity early adopts the ASU in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes the interim period. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In April 2016, the FASB issued ASU 2016-10, “ Revenue from Contracts with Customers (Topic 606). ” This Update amends the guidance in ASU 2014-09, Revenue from Contracts with Customers , and clarifies identifying performance obligations and the licensing implementation guidance. This Update better articulates the principle for determining whether promises to transfer goods or services are separately identifiable, which is utilized in identifying performance obligations in a contract. Additionally, the amendments in this Update are intended to improve the operability and understandability of the licensing implementation guidance. The amendments in ASU 2016-10 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. 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. In June 2016, the FASB issued ASU 2016-13, " Financial Instruments - Credit Losses (Topic 326). " 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. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230)." The amendments in this Update provide guidance on classification of certain cash receipts and cash payments. For public business entities that are SEC filers, this Update is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In October 2016, the FASB issued ASU 2016-17, “Consolidation (Topic 810). ” This Update amends the guidance in ASU 2015-02, Amendments to the Consolidation Analysis . Determining whether an entity is a primary beneficiary of VIE, ASU 2015-02 requires a single decision maker of a VIE to consider indirect economic interests in the entity held through related parties on a proportionate basis unless the decision maker and its related parties are under common control. If the decision maker and its related parties are under common control, the guidance requires the decision maker to deem the indirect interests to be the equivalent of direct interests in their entirety. However, under this Update, when the decision maker evaluates whether it is a primary beneficiary of the VIE, it will need to consider only its proportionate indirect interests in the VIE held through a common control party. This Update was effective for public business entities with their fiscal years beginning after December 15, 2016 including interim periods within those fiscal years. An entity that has adopted the amendments in Update 2015-12 is required to apply this Update retrospectively to all relevant prior periods since the Update 2015-02 adoption. The Company is in process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, “ Statement of Cash Flows (Topic 230) . ” The amendments in this Update intend to reduce diversity in practice regarding classification of changes in restricted cash; requiring an entity to provide change in restricted cash and restricted cash equivalents during the period in a statement of cash flows. This Update is effective for public business entities with their fiscal years beginning after December 15, 2017 including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If an entity adopts this Update in an interim period, any adjustment should be reflected as of the beginning of the fiscal year in a retrospective transition method to each period presented. The Company is in the process of evaluating the impact that adoption of this guidance may have on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805). ” The amendments in this Update provide a guidance on evaluating whether transactions should accounted for as acquisitions (or disposals) of assets or businesses. The current Topic 805 does not specify the minimum inputs and processes required for a set to meet the definition of a business, but the amendment in this Update presents more robust framework to use when an entity determines whether a set of assets and activities is a business. Also, the amendment in this Update sets forth more consistency in applying the guidance with cost savings and more operable definition of a business. Public business entities must prospectively apply the amendment 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). ” The amendments in this Update eliminate Step 2 from the goodwill impairment test resulting in the reduction of cost and complexity of evaluating goodwill for impairment. 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 by which the carrying amount exceeds the reporting unit’s fair value, but loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Furthermore, the amendment in this Update requires an entity to disclose the amount of goodwill allocated to each reporting unit with 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.

Summary of Amortized Cost and Fair Value of Available-for-Sale Investment Securities Portfolio	The following table presents amortized cost and fair value of the held-to-maturity and available-for-sale investment securities portfolio by expected maturity. 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.
