Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations— Hope Bancorp, Inc. (“Hope Bancorp” on a parent-only basis and the “Company” on a consolidated basis, previously known as BBCN Bancorp, Inc.), headquartered in Los Angeles, California, is the holding company for Bank of Hope (the “Bank,” previously known as BBCN Bank). The Bank has branches in California, Washington, Texas, Illinois, Alabama, Georgia, Virginia, New Jersey, and New York, as well as loan production offices in Atlanta, Dallas, Denver, Portland, Seattle, Newport Beach, Laguna Niguel, and Northern California. Hope Bancorp is a corporation organized under the laws of the state of Delaware and a bank holding company registered under the Bank Holding Company Act of 1956, as amended. The Bank is a California-chartered bank and its deposits are insured by the FDIC to the extent provided by law. The Company specializes in core business banking products for small and medium-sized businesses, with an emphasis in commercial real estate and business lending, SBA lending and international trade financing. Principles of Consolidation— The accounting and reporting policies of the Company are in accordance with accounting principles generally accepted in the United States of America and conform to practices within the banking industry. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, principally the Bank. Cash Flows —Cash and cash equivalents include cash and due from banks, interest-earning deposits, federal funds sold and term federal funds sold, which have original maturities less than 90 days. The Company may be required to maintain reserve and clearing balances with the Federal Reserve Bank under the Federal Reserve Act. The reserve and clearing requirement balance was $0 at December 31, 2016 . Net cash flows are reported for customer loan and deposit transactions, deferred income taxes, and other assets and liabilities. The Company identified that for the year ended December 31, 2015, commitments to fund investments in affordable housing partnerships had been included in both cash flows related to investing activities under the line item investments in affordable housing partnerships and offset with cash flows related to operating activities under the line item other liabilities. Since commitments to fund investments in affordable housing partnerships are obligations to fund these investments and not actual cash outflows, they should not have been included in investing activities or operating activities. The Company corrected the previously presented cash flows from investments in affordable housing partnerships and other liabilities to include only actual funded portions of investments in affordable housing partnerships and in doing so, the consolidated statements of cash flows for 2015 were adjusted to increase net cash flows from investing activities by $14.8 million , with corresponding decrease in net cash flows from operating activities. The Company has evaluated the effect of the incorrect presentation, both qualitatively and quantitatively, and concluded that it did not have a material impact on, nor require amendment of, the previously filed annual or quarterly consolidated financial statements. Securities— Securities are classified and accounted for as follows: (i) Securities that the Company has the positive intent and ability to hold to maturity are classified as “held to maturity” and reported at amortized cost. At December 31, 2016 and 2015 , we did not own securities in this category; (ii) Securities are classified as “available-for-sale” when they might be sold before maturity and are reported at fair value. Unrealized holding gains and losses are reported as a separate component of stockholders’ equity in accumulated other comprehensive income (loss), net of taxes. Accreted discounts and amortized premiums on securities are included in interest income using the interest method, and realized gains or losses related to sales of securities are calculated using the specific identification method, without anticipating prepayments, except for mortgage-backed securities where prepayments are expected. Management evaluates securities for other than temporary impairment (“OTTI”) at least on a quarterly basis and more frequently when economic conditions warrant such evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position 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: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI 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. Other Investments —Other investments are comprised of the Company’s investments in certificates of deposits that have original maturities greater than 90 days. Other investments are also comprised of the Company’s investment in funds to partially satisfy the Company’s requirements under the Community Reinvestment Act. The funds do not have a readily determinable fair value as of the balance sheet date. Derivative Financial Instruments and Hedging Transactions —As part of our asset and liability management strategy, we may enter into derivative financial instruments, such as interest rate swaps, and caps and floors, with the overall goal of minimizing the impact of interest rate fluctuations on our net interest margin. The Company’s interest rate swaps and caps involve the exchange of fixed rate and variable rate interest payment obligations without the exchange of the underlying notional amounts and are therefore accounted for as stand alone derivatives. Changes in the fair value of the stand alone derivatives are reported in earnings as noninterest income. Residential mortgage loans funded with interest rate lock commitments and forward commitments for the future delivery of mortgage loans to third party investors, are both considered derivatives. The Company accounts for loan commitments related to the origination of mortgage loans that will be held-for-sale as derivatives at fair value on the balance sheet, with changes in fair value recorded in earnings. As part of the Company’s overall risk management, the Company’s Asset Liability Committee, which meets monthly, monitors and measures interest rate risk and the sensitivity of assets and liabilities to interest rate changes, including the impact of derivative transactions. Loans— Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of any unearned interest, deferred loan fees and costs and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. Nonrefundable loan origination fees and certain direct origination costs are deferred and recognized in interest income using the level-yield method over the life of the loan. Interest on loans is credited to income as earned and is accrued only if deemed collectible. Generally, loans are placed on nonaccrual status and the accrual of interest is discontinued if principal or interest payments become 90 days past due and/or management deems the collectibility of the principal and/or interest to be in question. Loans to a customer whose financial condition has deteriorated are considered for nonaccrual status whether or not the loan is 90 days or more past due. Generally, payments received on nonaccrual loans are recorded as principal reductions. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Other loan fees and charges, representing service costs for the prepayment of loans, for delinquent payments or for miscellaneous loan services, are recorded as income when collected. Loans are categorized into risk categories based on relevant information about the ability of borrowers to service their debt, including, but not limited to, current financial information, historical payment experience, credit documentation, public information, and current economic trends. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes all non-homogeneous loans. This analysis is performed at least on a quarterly basis. The Company uses the following definitions for risk ratings: • Pass: Loans that meet a preponderance or more of the Company’s underwriting criteria and evidence an acceptable level of risk. • Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. • Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. • Doubtful/Loss: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or repayment in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Allowance for Loan Losses —The allowance for loan losses is a valuation allowance for probable incurred credit losses that are inherent in the loan portfolio. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers non-impaired loans and is based on historical loss experience adjusted for qualitative factors. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment. The Company further segregates these segments between loans accounted for under the amortized cost method (referred to as “Legacy Loans”) and acquired loans (referred to as “Acquired Loans”), as Acquired Loans were originally recorded at fair value with no carryover of the related allowance for loan losses. The historical loss experience for Legacy Loans is based on the actual loss history experienced by the Company. The loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. The following major portfolio segments have been identified: real estate loans (residential, commercial, and construction), commercial business loans, trade finance loans, and consumer/other loans. Due to the overall high level of real estate loans within the loan portfolio as a whole, as compared to other portfolio segments, for risk assessment and allowance purposes this segment was segregated into more granular pools by collateral property type. The Company uses a loan migration analysis which is a formula methodology based on the Bank’s actual historical net charge off experience for each loan class (type) pool and risk grade. The migration analysis is centered on the Bank’s internal credit risk rating system. The Company’s internal loan review and external contracted credit review examinations are used to determine and validate loan risk grades. This credit review system takes into consideration factors such as: borrower’s background and experience; historical and current financial condition; credit history and payment performance; economic conditions and their impact on various industries; type, fair value and volatility of the fair value of collateral; lien position; and the financial strength of any guarantors. A general loan loss allowance is provided on loans not specifically identified as impaired (“non-impaired loans”). The Bank’s general loan loss allowance has two components: quantitative and qualitative risk factors. The quantitative risk factors are based on a historical loss migration methodology. The loans are classified by class and risk grade and the historical loss migration is tracked for the various classes. Loss experience is quantified for a specified period and then weighted to place more significance to the most recent loss history. That loss experience is then applied to the stratified portfolio at each quarter end. Additionally, in order to systematically quantify the credit risk impact of other trends and changes within the loan portfolio, the Bank utilizes qualitative adjustments to the Migration Analysis within established parameters. The parameters for making adjustments are established under a Credit Risk Matrix that provides seven possible scenarios for each of the factors below. The matrix allows for up to three positive (major, moderate, and minor), three negative (major, moderate, and minor), and one neutral credit risk scenarios within each factor for each loan type pool. Generally, the factors are considered to have no significant impact (neutral) to our historical migration ratios. However, if information exists to warrant adjustment to the Migration Analysis, changes are made in accordance with the established parameters supported by narrative and/or statistical analysis. The Credit Risk Matrix and the nine possible scenarios enable the Bank to qualitatively adjust the Loss Migration Ratio by as much as 50 basis points in either direction (positive or negative) for each loan type pool. This matrix considers the following nine factors, which are patterned after the guidelines provided under the FFIEC Interagency Policy Statement on the Allowance for Loan and Lease Losses: • Changes in lending policies and procedures, including underwriting standards and collection, charge-off, and recovery practices. • Changes in national and local economic and business conditions and developments, including the condition of various market segments. • Changes in the nature and volume of the loan portfolio. • Changes in the experience, ability and depth of lending management and staff. • Changes in the trends of the volume and severity of past due loans, Classified Loans, nonaccrual loans, troubled debt restructurings and other loan modifications. • Changes in the quality of our loan review system and the degree of oversight by the Directors. • Changes in the value of underlying collateral for collateral-dependent loans. • The existence and effect of any concentrations of credit and changes in the level of such concentrations. • The effect of external factors, such as competition and legal and regulatory requirements, on the level of estimated losses in our loan portfolio. The Company also establishes specific loss allowances for loans where we have identified potential credit risk conditions or circumstances related to a specific individual credit. The specific allowance amounts are determined by a method prescribed by ASC 310-10-35-22, Measurement of Impairment . The loans identified as impaired will be accounted for in accordance with one of the three acceptable valuation methods: 1) the present value of future cash flows discounted at the loan’s effective interest rate; 2) the loan’s observable market price; or 3) the fair value of the collateral, if the loan is collateral dependent. For the collateral dependent impaired loans, we obtain a new appraisal to determine the amount of impairment as of the date that the loan became impaired. The appraisals are based on an “as is” valuation. To ensure that appraised values remain current, the Company either obtains updated appraisals every twelve months from a qualified independent appraiser or an internal re-valuation of the collateral is performed by qualified personnel. If the fair value of the collateral, less cost to sell, is less than the recorded amount of the loan, we then recognize impairment by creating or adjusting an existing valuation allowance with a corresponding charge to the provision for loan losses. If an impaired loan is expected to be collected through liquidation of the underlying collateral, the loan is deemed to be collateral dependent and the amount of impairment is charged off against the allowance for loan losses. The Bank considers a loan to be impaired when it is probable that not all amounts due (principal and interest) will be collectible in accordance with the contractual terms of the loan agreement. 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. The significance of payment delays and payment shortfalls is determined on a case-by-case basis by 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. For commercial business loans, real estate loans and certain consumer loans, the Company bases the measurement of loan impairment on the present value of the expected future cash flows, discounted at the loan’s effective interest rate or on the fair value of the loan’s collateral, less estimated costs to sell, if the loan is collateral dependent. Management evaluates most consumer loans for impairment on a collective basis because these loans generally have smaller balances and are homogeneous in the underwriting of terms and conditions and in the type of collateral. Impairment losses are included in the allowance for loan losses through a charge to the provision for loan losses. Upon disposition of an impaired loan, any unpaid balance is charged off to the allowance for loan losses. The allowance for loan losses for acquired credit impaired loans is based upon expected cash flows for these loans. To the extent that a deterioration in borrower credit quality results in a decrease in expected cash flows subsequent to the acquisition of the loans, an allowance for loan losses would be established based on management’s estimate of future credit losses over the remaining life of the loans. Acquired Loans —Loans that the Company acquires are recorded at fair value with no carryover of the related allowance for loan losses. On the date of acquisition, the Company considers acquired classified loans credit impaired loans (“Purchased Credit Impaired Loans” or “PCIs”) under the provisions of Accounting Standards Codification (“ASC”) 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality . On the date of acquisition, loans without credit impairment (“Acquired Performing Loans” or “Non-PCIs”) are not accounted for under ASC 310-30. Acquired loans are placed in pools with similar risk characteristics and recorded at fair value as of the acquisition date. For PCI loans, the cash flows expected to be received over the life of the pools were estimated by management with the assistance of a third party valuation specialist. These cash flows were utilized in calculating the carrying values of the pools and underlying loans, book yields, effective interest income and impairment, if any, based on actual and projected events. Default rates, loss severity and prepayment speed assumptions are periodically reassessed and updated within the accounting model to update the expectation of future cash flows. The excess of the cash expected to be collected over the pools’ carrying value is considered to be the accretable yield and is recognized as interest income over the estimated life of the loan or pool using the effective interest yield method. The accretable yield may change due to changes in the timing and amounts of expected cash flows. Changes in the accretable yield is disclosed quarterly. For PCI loans, the excess of the contractual balances due over the cash flows expected to be collected is considered to be nonaccretable difference. The nonaccretable difference represents our estimate of the credit losses expected to occur and was considered in determining the fair value of the loans as of the date of acquisition. Subsequent to the date of acquisition, any increases in expected cash flows over those expected at purchase date in excess of fair value are adjusted through the accretable difference on a prospective basis. Any subsequent decreases in expected cash flows over those expected at the acquisition date are recognized by recording a provision for loan losses that will maintain the original expected yield. PCI loans that met the criteria for nonaccrual of interest prior to the acquisition may be considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if management can reasonably estimate the timing and amount of the expected cash flows on such loans and if management expects to fully collect the new carrying value of the loans. As such, management may no longer consider the loan to be nonaccrual or nonperforming and may accrue interest on these loans, including the impact of any accretable discount. Management has determined that future cash flows are reasonably estimable on any such acquired loans that are past due 90 days or more and accruing interest. Management expects to fully collect the carrying value of the loans. Loans Held for Sale —Small Business Administration (“SBA”) and residential mortgage loans that the Company has the intent to sell prior to maturity have been designated as held for sale at origination and are recorded at the lower of cost or fair value, on an aggregate basis. A valuation allowance is established if the aggregate fair value of such loans is lower than their cost and charged to earnings. Gains or losses recognized upon the sale of loans are determined on a specific identification basis. Loan transfers are accounted for as sales when control over the loan has been surrendered. Control over such loans is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Company does not maintain control over the transferred assets through an agreement to repurchase them before their maturity. Loan Servicing Assets— The Company typically sells the guaranteed portion of SBA loans and retains the unguaranteed portion (“retained interest”). A portion of the premium on sale of SBA loans is recognized as gain on sale of loans at the time of the sale by allocating the carrying amount between the asset sold and the retained interest, including these servicing assets, based on their relative fair values. The remaining portion of the premium is recorded as a discount on the retained interest and is amortized over the remaining life of the loan as an adjustment to yield. The retained interest, net of any discount, are included in loans receivable—net of allowance for loan losses in the accompanying consolidated statements of financial condition. Servicing assets are recognized when SBA and residential mortgage loans are sold with servicing retained with the income statement effect recorded in gains on sales of loans. Servicing assets are initially recorded at fair value 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. The Company’s servicing costs approximates the industry average servicing costs of 40 basis points. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Management periodically evaluates servicing assets for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. No impairment charges were required in 2016 , 2015 , or 2014 . FHLB Stock —The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB 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 as income. Premises and Equipment —Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization of premises and equipment are computed on the straight-line method over the following estimated useful lives: Buildings 15 - 30 years Furniture, fixture, and equipment 3 - 7 years Computer equipment 1 - 5 years Computer software 1 - 5 years Leasehold improvement life of lease or improvements, whichever is shorter OREO —OREO, which represents real estate acquired through foreclosure in satisfaction of commercial and real estate loans, is stated at fair value less estimated selling costs of the real estate. Loan balances in excess of the fair value of the real estate acquired at the date of acquisition are charged to the allowance for loan losses. Any subsequent operating expenses or income, reduction in estimated fair values, and gains or losses on disposition of such properties are charged or credited to current operations. For the year ended December 31, 2016 , the Company foreclosed on properties with an aggregate carrying value of $5.6 million and acquired $14.9 million in OREO from the acquisition of Wilshire. The Company recorded $2.2 million in valuation adjustments subsequent to the foreclosures, and the Company sold OREO properties for total proceeds of $17.4 million. Goodwill and Intangible Assets— Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. In accordance with Accounting Standards Update (“ASU”) 2011-08, Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment , the Company makes a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying the two-step goodwill impairment test. If management concludes that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, the two-step impairment test is bypassed. Goodwill is also tested for impairment on an interim basis if circumstances change or an event occurs between annual tests that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions and selecting an appropriate control premium. The selection and weighting of the various fair value techniques may result in a higher or lower fair value. Judgment is applied in determining the weighting that is most representative of fair value. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Core deposit intangibles are amortized over a seven to 10 year period. Stock-Based Compensation— Compensation cost is recognized for 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, 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 —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 income tax assets and liabilities represent the tax effects, based on current tax law, of future deductible or taxable amounts attributable to events that have been recognized in the financial statements. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, the projected future taxable income and tax planning strategies in making this assessment. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and / or penalties related to income tax matters in income tax expense.

Business Combinations [Abstract]
Mergers and Acquisitions	MERGERS AND ACQUISITIONS Merger with Wilshire Bancorp Inc. On July 29, 2016, the merger of Wilshire Bancorp Inc. (“Wilshire”) and BBCN Bancorp, Inc. (now Hope Bancorp) was completed. On the same day BBCN changed its name to Hope Bancorp, Inc. and the subsidiary BBCN Bank was changed to Bank of Hope. The Company merged with Wilshire to create the only super regional Korean-American Bank in the Untied States and to expand our branch network nationwide. Pursuant to the merger agreement, holders of Wilshire common stock received 0.7034 of a share of common stock of HOPE for each share of Wilshire common stock held immediately prior to the effective time of the merger, rounded to the nearest whole share, plus cash in lieu of the issuance of fractional shares. Outstanding Wilshire stock options and restricted stock awards were converted into stock options with respect to shares of HOPE common stock or shares of HOPE common stock, respectively, with appropriate adjustments to reflect the exchange ratio. The merger was accounted for using the acquisition method of accounting. Accordingly, the assets and liabilities of Wilshire were recorded at their respective fair values and represents management’s estimates based on available information. The consideration paid, the assets acquired, and the liabilities assumed are summarized in the following table: (Dollars in thousands) July 29, 2016 Consideration Paid: Hope common stock issued in exchange for Wilshire common stock $ 852,939 Cash paid for fractional shares 3 Hope stock options issued in exchange Wilshire stock options 3,370 Total consideration paid $ 856,312 Assets Acquired: Cash and cash equivalents $ 100,127 Investment securities 478,938 Loans receivable 3,800,807 FRB and FHLB stock 16,539 OREO 14,866 Premises and equipment 16,812 BOLI 25,240 Servicing assets 16,203 Low income housing tax credit investments 47,111 Core deposit intangibles 18,138 Deferred tax assets, net 17,458 Other assets 76,818 Liabilities Assumed: Deposits (3,812,367 ) Borrowings (206,282 ) Subordinated debentures (56,942 ) Other liabilities (54,751 ) Total identifiable net assets $ 498,715 Excess of consideration paid over fair value of net assets acquired (goodwill) $ 357,597 Fair values are primarily determined through the use of inputs that are not observable from market-based information. Under ASC 805-10-25-13, management may adjust the fair values of acquired assets or assumed liabilities for a period of up to one year from the date of the acquisition to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have an affect on the measurement of the amounts recognized as of that date. During the fourth quarter of 2016, the Company made a net adjustment of $1.4 million to the deferred tax assets and taxes receivable acquired from Wilshire which reduced the previous goodwill recorded from the transaction by $1.4 million . Acquired Loans The fair value of loans were estimated on an individual basis based on the characteristics for each loan. A discounted cash flow analysis was used to project cash flows for each loan using assumptions for rate, remaining maturity, prepayment speeds, projected default probabilities, loss given defaults, and estimate of prevailing discount rates. The following table presents loans acquired from Wilshire with deteriorated credit quality as of the date of acquisition included as loans receivable in the table above: Fair Value At July 29, 2016 (Dollars in thousands) Contractually required principal and interest at acquisition $ 292,380 Contractual cash flows not expected to be collected (nonaccretable discount) (40,560 ) Expected cash flows at acquisition 251,820 Interest component of expected cash flows (accretable discount) (8,713 ) Fair value of acquired impaired loans $ 243,107 The outstanding principal balances and the related carrying amounts of the acquired loans included in the statement of financial condition at December 31, 2016 were $5.67 billion and $3.59 billion , respectively, for loans acquired from Wilshire. Pro Forma Information The following table presents financial information regarding the Wilshire’s operations included in our Consolidated Statement of Income from the date of acquisition through December 31, 2016. The table also presents unaudited pro forma information as if the merger had occurred on January 1, 2015. This pro forma information gives effect to certain adjustments, including purchase accounting fair value adjustments, amortization of core deposit and related income tax effects. Merger and integration expenses incurred of $25.7 million and $1.4 million for the years ended December 31, 2016 and 2015, respectively, were excluded. The pro forma information does not necessarily reflect the results of operations that would have occurred had the Company merged with Wilshire at the beginning of 2015. The pro forma combined condensed consolidated financial statements do not take into account the impact, if any, of an ownership change under Section 382 of the Code that would have occurred as of January 1, 2015. The merger is expected to result in annual cost savings to be achieved following the consummation of the merger. These expected savings have not been included in the pro forma combined amounts. These pro forma results require significant estimates and judgments particularly as it relates to the valuation and accretion of income associated with acquired loans. Actual from Acquisition Date Through December 31, Pro forma Year Ended December 31, 2016 2016 2015 (Dollars in thousands) Net interest income $ 197,953 $ 456,556 $ 449,501 Provision for loan losses 6,490 4,000 8,700 Non-interest income 29,546 75,266 89,345 Non-interest expense 120,954 235,013 255,401 Income tax provision 39,828 $ 118,613 $ 111,581 Net income $ 60,227 $ 174,196 $ 163,164 Pro forma earnings per share: Basic $ 1.29 $ 1.21 Diluted $ 1.29 $ 1.21 Acquisition-Related Expenses The following table presents acquisition-related expenses associated with the acquisition of Wilshire and other previous acquisitions which were reflected in the Consolidated Statements of Income in merger and integration expense. These expenses are comprised primarily of severance payments, professional services, and other noninterest expense related to prior acquisitions. Twelve Months Ended December 31, 2016 2015 (Dollars in thousands) Wilshire $ 16,818 $ 1,414 Other 96 126 Total merger related expenses $ 16,914 $ 1,540 Federally Assisted Acquisition of Mirae Bank The FDIC placed Mirae Bank (“Mirae”) under receivership upon Mirae’s closure by the California Department of Business Oversight (“DBO”) at the close of business on June 26, 2009. Wilshire purchased substantially all of Mirae’s assets and assumed all of Mirae’s deposits and certain other liabilities. Further, the Company entered into loss sharing agreements with the FDIC in connection with the Mirae acquisition. In June, 2014, the remaining loss-share agreement with the FDIC related to losses expired. As such, losses on loans acquired from Mirae Bank are no longer covered by the FDIC. However, recoveries will still be shared with the FDIC until June 2017. Pending Acquisition of U & I Financial Corp On January 23, 2017, the Company announced the signing of a definitive agreement and plan of merger (the “Merger Agreement”) with U & I Financial Corporation (“U & I”) pursuant to which U & I will merge (the “merger”) with and into Hope Bancorp with Hope Bancorp as the surviving corporation. As part of the merger, UniBank, a wholly-owned subsidiary of U & I, will merge with and into the Bank. Under the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each outstanding share of U & I common stock will be converted into shares of the Company’s common stock based on a value of $9.50 for the U & I common stock, which value will be subject to adjustment if U & I’s financial advisory and legal fees exceed certain amounts as provided in the Merger Agreement (the “Merger Consideration”). The number of shares of Company common stock to be issued for the Merger Consideration will be based on the 10-day trade weighted, volume weighted average price of the Company’s common stock as of the closing as determined in accordance with the Merger Agreement (as so determined, the “Closing Stock Price”); provided that: (i) if the Closing Stock Price is less than $17.28832, the Company may terminate the Merger Agreement unless U & I Financial elects to accept an adjustment to the Merger Consideration through the issuance of fewer shares based on the $17.28832 instead of the lower Closing Stock Price; and (ii) if the Closing Stock Price is greater than $25.93248, U & I may terminate the Merger Agreement unless the Company elects to accept an adjustment to the Merger Consideration through the issuance of additional shares based on the $25.93248 price instead of the higher Closing Stock Price. Each outstanding U & I stock option held by an U & I employee who will be retained by the Company after the Effective Time (each, a “Covered Employee”) shall cease to represent the right to acquire shares of U & I common stock and shall instead be converted automatically into an option to acquire shares of the Company’s common stock, and such assumed options will be assumed by the Company on substantially the same terms and conditions as were applicable under the corresponding U & I stock options. Each U & I stock option held by a U & I employee who will not be a Covered Employee shall become fully vested and be converted into the right to receive an amount in cash equal to the product obtained by multiplying (i) the excess, if any, of the per share Merger Consideration over the exercise price per share of such stock option by (ii) the total number of shares of U & I common stock subject to such stock option. The Merger Agreement contains representations and warranties customary for transactions of this type from the Company and U & I, and each party has agreed to customary covenants, including, among others, covenants relating to the conduct of its business during the interim period between the execution of the Merger Agreement and the Effective Time and, in the case of U & I, its obligation, subject to certain exceptions, to recommend that its shareholders adopt the Merger Agreement and its non-solicitation obligations relating to alternative acquisition proposals. The consummation of the Merger is subject to customary conditions, including receipt of regulatory approvals, receipt of the requisite approval of the shareholders of U & I, the absence of any law or order prohibiting the closing, and effectiveness of the registration statement to be filed by the Company with respect to the Company’s common stock to be issued in the Merger, and the absence of the occurrence of a material adverse effect upon the Company or U & I. In addition, each party’s obligation to consummate the Merger is subject to certain other conditions, including the accuracy of the representations and warranties of the other party and compliance of the other party with its covenants, in each case subject to certain materiality standards. The Merger Agreement provides certain termination rights for both the Company and U & I and further provides that a termination fee of $2 million will be payable by U & I to the Company upon termination of the Merger Agreement under certain circumstances.

Consideration is given to the financial condition and near-term prospects of the issuer, the length of time and the extent to which the fair value of the securities has been less than our cost for the securities, and management’s intention to sell, or whether it is more likely than not that management will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. In analyzing an issuer’s financial condition, the Company considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer’s financial condition. The Company has certain trust preferred securities, collateralized mortgage obligations, and mortgage-backed securities that were in a continuous loss position for twelve months or longer as of December 31, 2016 . The corporate securities in a continuous loss position for twelve months or longer had an unrealized loss of $447 thousand at December 31, 2016 and are scheduled to mature in May 2047. These securities were rated investment grade and there were no credit quality concerns with the obligator. The collateralized mortgage obligations in a continuous loss position for twelve months or longer had an unrealized loss of $1.2 million at December 31, 2016. These securities were investments in U.S. Government agency and U.S. Government sponsored enterprises and have high credit ratings (“AA” grade or better). The interest on the securities that were in an unrealized loss position have been paid as agreed, and management believes this will continue in the future and that the securities will be paid in full as scheduled. The market value declines are deemed to be due to the current market volatility and are not reflective of management’s expectations of the Company’s ability to fully recover the investments, which may be at maturity. For these reasons, no OTTI was recognized on the securities that were in a continuous loss position for twelve months or longer at December 31, 2016 . The Company considers the losses on our investments in unrealized loss positions at December 31, 2016 to be temporary based on: 1) the likelihood of recovery; 2) the information relative to the extent and duration of the decline in market value; and 3) the Company’s intention not to sell, and management’s determination that it is more likely than not that the Company will not be required to sell a security in an unrealized loss position before recovery of its amortized cost basis. The increase in the net unrealized gain position can be attributed to an increase in long term Treasury yields at December 31, 2016 , compared to rates at December 31, 2015 .

Loans Receivable and Allowance for Loan Losses	The following is a summary of loans by major category at December 31, 2016 and 2015 : December 31, 2016 December 31, 2015 Loan portfolio composition (Dollars in thousands) Real estate loans: Residential $ 57,884 $ 33,797 Commercial & industrial 7,842,573 4,912,655 Construction 254,113 123,030 Total real estate loans 8,154,570 5,069,482 Commercial business 1,832,021 980,153 Trade finance 154,928 99,163 Consumer and other 403,470 102,573 Total loans outstanding 10,544,989 6,251,371 Less: deferred loan fees (1,657 ) (3,030 ) Gross loans receivable 10,543,332 6,248,341 Less: allowance for loan losses (79,343 ) (76,408 ) Loans receivable, net $ 10,463,989 $ 6,171,933 Our loan portfolio is made up of four segments: real estate loans, commercial business, trade finance and consumer and other. These segments are further segregated between loans accounted for under the amortized cost method ("Legacy Loans") and acquired loans that were originally recorded at fair value with no carryover of the related pre-acquisition allowance for loan losses ("Acquired Loans"). The Acquired Loans are further segregated between Purchased Credit Impaired Loans (loans with credit deterioration on the acquisition date and accounted for under ASC 310-30, or "PCIs") and Acquired Performing Loans (loans that were pass graded on the acquisition date and the fair value adjustment is amortized over the contractual life under ASC 310-20, or "non-PCIs"). The following table presents changes in the accretable discount on the PCI loans for the years ended December 31, 2016 and 2015 : Year ended December 31, 2016 2015 (Dollars in thousands) Balance at beginning of period $ 23,777 $ 24,051 Additions due to mergers and acquisitions 8,713 — Accretion (15,817 ) (12,633 ) Changes in expected cash flows 21,918 12,359 Balance at end of period $ 38,591 $ 23,777 On the acquisition date, the amount by which the undiscounted expected cash flows exceed the estimated fair value of the PCI loans is the “accretable yield”. The accretable yield is then measured at each financial reporting date and represents the difference between the remaining undiscounted expected cash flows and the current carrying value of the loans. The accretable yield may increase from period to period due to the following: 1) estimates of the remaining life of acquired loans will affect the amount of future interest income, 2) indicies for variable rates of interest on PCI loans may change; and 3) estimates of the amount of the contractual principal and interest that will not be collected (nonaccretable difference) may change.

(2) Nonaccrual loans exclude the guaranteed portion of delinquent SBA loans that are in liquidation totaling $18.7 million . Loans accounted for under ASC 310-30 are generally considered accruing and performing loans and the accretable discount is accreted to interest income over the estimate life of the loan when cash flows are reasonably estimable. Accordingly, PCI loans that are contractually past due are still considered to be accruing and performing loans. The loans may be classified as nonaccrual if the timing and amount of future cash flows is not reasonably estimable.

These modifications are either temporary in nature (“temporary modifications”) or are more substantive. At December 31, 2016 , total modified loans were $70.9 million , compared to $72.2 million at December 31, 2015 . The temporary modifications generally consist of interest only payments for a three to six month period, whereby principal payments are deferred. At the end of the modification period, the remaining principal balance is re-amortized based on the original maturity date. Loans subject to temporary modifications are generally downgraded to Substandard or Special Mention. At the end of the modification period, the loan either 1) returns to the original contractual terms; 2) is further modified and accounted for as a troubled debt restructuring in accordance with ASC 310-10-35; or 3) is disposed of through foreclosure or liquidation. Troubled Debt Restructurings (“TDRs”) of loans are defined by ASC 310-40, Troubled Debt Restructurings by Creditors , and ASC 470-60, Troubled Debt Restructurings by Debtors, and evaluated for impairment in accordance with ASC 310-10-35. 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 our internal underwriting policy. A summary of TDRs on accrual and nonaccrual by type of concession as of December 31, 2016 , December 31, 2015 , and December 31, 2014 is presented below: As of December 31, 2016 TDRs on accrual TDRs on nonaccrual Total Real estate - Commercial Commercial Business Other Sub-Total Real estate - Commercial Commercial Business Other Sub-Total (Dollars in thousands) Payment concession $ 16,358 $ 29 $ — $ 16,387 $ 4,417 $ 1,717 $ — $ 6,134 $ 22,521 Maturity / Amortization concession 1,840 17,471 4,600 23,911 1,313 6,130 2,287 9,730 33,641 Rate concession 6,856 1,665 55 8,576 5,590 387 155 6,132 14,708 Principal forgiveness — — — — — — — — — Total $ 25,054 $ 19,165 $ 4,655 $ 48,874 $ 11,320 $ 8,234 $ 2,442 $ 21,996 $ 70,870 As of December 31, 2015 TDRs on accrual TDRs on nonaccrual Total Real estate - Commercial Other Sub-Total Real estate - Commercial Other Sub-Total (Dollars in thousands) Payment concession $ 11,604 $ 375 $ — $ 11,979 $ 3,891 $ 2,410 $ — $ 6,301 $ 18,280 Maturity / Amortization concession 4,009 18,192 5,311 27,512 1,583 6,818 2,297 10,698 38,210 Rate concession 7,215 1,278 — 8,493 6,445 641 166 7,252 15,745 Principal forgiveness — — — — — — — — — Total $ 22,828 $ 19,845 $ 5,311 $ 47,984 $ 11,919 $ 9,869 $ 2,463 $ 24,251 $ 72,235 As of December 31, 2014 TDRs on accrual TDRs on nonaccrual Total Real estate - Commercial Other Sub-Total Real estate - Commercial Other Sub-Total (Dollars in thousands) Payment concession $ 12,235 $ 556 $ — $ 12,791 $ 3,840 $ 517 $ — $ 4,357 $ 17,148 Maturity / Amortization concession 2,189 20,053 3,387 25,629 1,207 3,158 1,550 5,915 31,544 Rate concession 13,684 5,024 — 18,708 8,473 80 176 8,729 27,437 Principal forgiveness — — — — — 15 — 15 15 Total $ 28,108 $ 25,633 $ 3,387 $ 57,128 $ 13,520 $ 3,770 $ 1,726 $ 19,016 $ 76,144 TDRs on accrual status are comprised of loans that were accruing at the time of restructuring and for which the Bank anticipates full repayment of both principal and interest under the restructured terms. TDRs that are on nonaccrual can be returned to accrual status after a period of sustained performance, generally determined to be six months of timely payments as modified. Sustained performance includes the periods prior to the modification if the prior performance met or exceeded the modified terms. TDRs on accrual status at December 31, 2016 were comprised of 20 commercial real estate loans totaling $25.1 million , 23 commercial business loans totaling $19.2 million and 19 consumer and other loans totaling $4.7 million . TDRs on accrual status at December 31, 2015 were comprised of 24 commercial real estate loans totaling $22.8 million , 28 commercial business loans totaling $19.8 million , and 4 consumer and other loans totaling $5.3 million . TDRs on accrual status at December 31, 2014 were comprised of 24 commercial real estate loans totaling $28.1 million , 30 commercial business loans totaling $25.6 million , and 3 consumer loans totaling $3.4 million . Management expects that the TDRs on accrual status as of December 31, 2016 , which were all performing in accordance with their restructured terms, will continue to comply with the restructured terms because of the reduced principal or interest payments on these loans. TDRs that were restructured at market interest rates and had sustained performance as agreed under the modified loan terms may be reclassified as non-TDRs after each year end but are still monitored for potential impairment. The Company has allocated $5.3 million , $5.7 million , and $5.7 million of specific reserves to TDRs as of December 31, 2016 , 2015 , and 2014 , respectively.

Subordinated Borrowings [Abstract]
Subordinated Debentures	SUBORDINATED DEBENTURES At December 31, 2016 , the Company had nine wholly-owned subsidiary grantor trusts that had issued $126 million of pooled trust preferred securities. Trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in the indentures. The trusts used the net proceeds from the offering to purchase a like amount of subordinated debentures (the “Debentures”) of the Company. The Debentures are the sole assets of the trusts. The Company’s obligations under the subordinated debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the trusts. The trust preferred securities are mandatorily redeemable upon the maturity of the Debentures, or upon earlier redemption as provided in the indentures. The Company has the right to redeem the Debentures in whole (but not in part) on or after specific dates, at a redemption price specified in the indentures plus any accrued but unpaid interest to the redemption date. The Company also has a right to defer consecutive payments of interest on the debentures for up to five years.

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. 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 evaluates both positive and negative evidence, 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, the forecasts of future income, applicable tax planning strategies, and assessments of current and future economic and business conditions. This analysis is updated quarterly and adjusted as necessary. Based on the analysis, the Company has determined that a valuation allowance for deferred tax assets was not required as of December 31, 2016 and 2015 .

The statute of limitations for the assessment of taxes for the consolidated Federal income tax return is closed for all tax years up to and including 2012. The expiration of the statute of limitations for the assessment of taxes for the various state income and franchise tax returns for the Company and subsidiaries varies by state. The Company is currently under examination by the California Franchise Tax Board (FTB) for the 2012, and 2013 tax years. Wilshire Bancorp Inc., an acquired entity, is currently under examination by the FTB for the 2011, 2012, and 2013 tax years and by the New York State Department of Taxation and Finance for the 2011, 2012, 2013, and 2014 tax years. While the outcomes of the examinations are unknown, the Company does not expect any material adjustments. A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2016 and 2015 is as follows: 2016 2015 (Dollars in thousands) Balance at January 1, $ 1,816 $ 1,816 Additions based on tax positions related to the prior year through acquisition 1,399 — Expiration of the statute of limitations for assessment of taxes (916 ) — Settlements with taxing authorities (112 ) — Balance at December 31, $ 2,187 $ 1,816 The total amount of unrecognized tax benefits was $2.2 million at December 31, 2016 and $1.8 million at December 31, 2015 and is primarily for uncertainties related to California enterprise zone loan interest deductions taken in prior years. The total amount of tax benefits that, if recognized, would favorably impact the effective tax rate was $1.6 million and $1.3 million at December 31, 2016 and 2015 , respectively. The Company expects the total amount of unrecognized tax benefits to decrease by $1.0 million within the next twelve months due to the settlement with the state tax authority. The Company recognizes interest and penalties related to income tax matters in income tax expense. The Company had approximately $306 thousand and $154 thousand for interest and penalties accrued at December 31, 2016 and 2015 , respectively.

Stock-Based Compensation

Stock-Based Compensation	12 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION The Company has a stock-based incentive plan, the 2007 BBCN Bancorp Equity Incentive Plan (“2007 Plan”). The 2007 Plan, approved by the Company’s stockholders on May 31, 2007, was amended and restated on July 25, 2007 and again on December 1, 2011. The 2007 Plan provides for grants of stock options, stock appreciation rights (“SARs”), restricted stock, performance shares and performance units (sometimes referred to individually or collectively as “awards”) to non-employee directors, officers, employees and consultants of the Company. Stock options may be either incentive stock options (“ISOs”), as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), or nonqualified stock options (“NQSOs”). The 2007 Plan gives the Company flexibility to (i) attract and retain qualified non-employee directors, executives and other key employees and consultants with appropriate equity-based awards, (ii) motivate high levels of performance, (iii) recognize employee contributions to the Company’s success, and (iv) align the interests of the 2007 Plan participants with those of the Company’s stockholders. The exercise price for shares under an ISO may not be less than 100% of fair market value on the date the award is granted under Code Section 422. Similarly, under the terms of the 2007 Plan, the exercise price for SARs and NQSOs may not be less than 100% of fair market value on the date of grant. Performance units are awarded to a participant at the market price of the Company’s common stock on the date of award (after the lapse of the restriction period and the attainment of the performance criteria). No minimum exercise price is prescribed for performance shares and restricted stock awarded under the 2007 Plan. ISOs, SARs and NQSOs have vesting periods of three to five years and have 10 -year contractual terms. Restricted stock, performance shares, and performance units will be granted with a restriction period of not less than one year from the grant date for performance-based awards and not more than three years from the grant date for time-based vesting of grants. Compensation expense for awards is recorded over the vesting period . The grant date fair value of stock option awards are estimated on the date of grant using the Black-Scholes option valuation model. The expected life (estimated period of time outstanding) of options is estimated using the simplified method. The expected volatility is based on historical volatility for a period equal to the stock option’s expected life. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. The Company has another stock-based incentive plan, the 2016 Stock Incentive Plan, adopted September 1, 2016. Stock options and restricted stock were assumed from the acquisition of Wilshire at substantially the same terms as those prior to the acquisition after applying the exchange ratio of 0.7034 . These stock awards were issued to former Wilshire employees and directors through the 2016 Plan. The 2016 Plan provides for the granting of incentive stock option, stock appreciation right, and restricted stock awards to officers, employees, and consultants. The plan has 2,400,000 shares available for grant to participants. The option prices of all options granted under the 2016 Plan may not be less than 100% of the fair market value at the date of grant. All options not exercised generally expire ten years after the date of grant. Under the 2007 and 2016 plans 1,890,563 shares were available for future grants as of December 31, 2016 . The total shares reserved for issuance will serve as the underlying value for all equity awards under the 2007 Plan and the 2016 Plan. With the exception of the shares underlying stock options and restricted stock awards, the board of directors may choose to settle the awards by paying the equivalent cash value or awarding the appropriate number of shares. For the year ended December 31, 2016 , 424,908 shares of restricted and performance unit awards were granted under the 2007 and 2016 Plans.

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	EMPLOYEE BENEFIT PLANS Deferred Compensation Plan — The Company established a deferred compensation plan that permits eligible officers, key executives and directors to defer a portion of their compensation. The deferred compensation plan is still in effect and was amended in 2007 to be in compliance with the new IRC §409(A) regulations. The deferred compensation, together with accrued accumulated interest, is distributable in cash after retirement or termination of service. The deferred compensation liabilities at December 31, 2016 and 2015 amounted to $1.2 million and $1.2 million , respectively, which are included in other liabilities in the accompanying consolidated statement of financial condition. Interest expense recognized under the deferred compensation plan totaled $23 thousand , $25 thousand and $28 thousand for 2016 , 2015 and 2014 , respectively. The Company established and the Board approved a Long Term Incentive Plan (“LTIP”) that rewards the named executive officers (“NEO”) with deferred compensation if the Company meets certain performance goals, the NEOs meet individual performance goals, and the NEOs remain employed for a pre-determined period (between five and ten years, depending on the officer). Only two NEOs are currently participating in the LTIP. The Company accrued $418 thousand , $306 thousand , and $228 thousand in 2016 , 2015 , and 2014 , respectively. The Company has insured the lives of certain officers and directors who participate in the deferred compensation plan. The Company has also purchased life insurance policies and entered into split dollar life insurance agreements with certain directors and officers. Under the terms of the split dollar life insurance agreements, a portion of the death benefits received by the Company will be paid to beneficiaries named by the directors and officers. 401(k) Savings Plan— The Company established a 401(k) savings plan, which is open to all eligible employees who are 21 years old or over and have completed three months of service. The Company matches 100% of the first 3% of the employee’s compensation contributed. The Company then matches 75% of the next 2% of the employee’s compensation contributed. Employer matching is immediately vested in full regardless of the service term. Total employer contributions to the plan amounted to approximately $2.6 million , $2.3 million and $1.9 million for 2016 , 2015 and 2014 , respectively. Post-Retirement Benefit Plans— In 2016, the Company assumed Wilshire’s Survivor Income Plan which was adopted in 2003 for the benefit of the directors and officers of the bank in order to encourage their continued employment and service, and to reward them for their past contributions. Wilshire had also entered into separate Survivor Income Agreements with officers and directors relating to the Survivor Income Plan. Under the terms of the Survivor Income Plan, each participant is entitled to a base amount of death proceeds as set forth in the participant’s election to participate, which base amount increases three percent per calendar year, but only until normal retirement age, which is 65 . If the participant remains employed after age 65, the death benefit will be fixed at the amount determined at age 65. If a participant has attained age 65 prior to becoming a participant in the Survivor Income Plan, the death benefit shall be equal to the base amount set forth in their election to participate with no increases. We are obligated to pay any death benefit owed under the Survivor Income Plan in a lump sum within 90 days following the participant’s death. In 2011, the Company assumed Center Bank’s Survivor Income Plan which was adopted in 2004 for the benefit of the directors and officers of the bank in order to encourage their continued employment and service, and to reward them for their past contributions. Under the terms of the Survivor Income Plan, each participant is entitled to a base amount of death proceeds as set forth in the participant’s election to participate. We are obligated to pay any death benefit owed under the Survivor Income Plan in a lump sum within 90 days following the participant’s death. The participant’s rights under the Survivor Income Plans terminate upon termination of employment. Upon termination of employment (except for termination for cause), if the participant has achieved the vesting requirements outlined in the plan, the participant will have the option to convert the amount of death benefits calculated at such termination to a split dollar arrangement, provided such arrangement is available under bank regulations and/or tax laws. If available, the Bank and the participant will enter into a split dollar agreement and a split dollar policy endorsement. Under such an arrangement, we would annually impute income to the officer or the director based on tax laws or rules in force upon conversion. The Company’s accumulated post-retirement benefit obligation at December 31, 2016, 2015, and 2014 was $6.6 million , $1.5 million , and $1.5 million , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Lease Commitments The Company leases its premises under non-cancelable operating leases, and at December 31, 2016 , the future minimum rental commitments under these leases are as follows: Amount (Dollars in thousands) 2017 $ 13,853 2018 10,902 2019 8,729 2020 6,088 2021 4,888 Thereafter 6,599 $ 51,059 Operating lease expense recorded under such leases in 2016 , 2015 and 2014 amounted to approximately $14.7 million , $11.1 million and $11.6 million , respectively. Legal Contingencies In the normal course of business, the Company is involved in various legal claims. Management has reviewed all legal claims against the Company with counsel for the fiscal year ended December 31, 2016 , and has taken into consideration the views of such counsel as to the outcome of the claims. Accrued loss contingencies for all legal claims totaled approximately $557 thousand at December 31, 2016 . There were no accrued loss contingencies for legal claims at December 31, 2015 . It is reasonably possible we may incur losses in addition to the amounts we have accrued. However, at this time, we are unable to estimate the range of additional losses that are reasonably possible because of a number of factors, including the fact that certain of these litigation matters are still in their early stages and involve claims for which, at this point, we believe have little to no merit. Management has considered these and other possible loss contingencies and does not expect the amounts to be material to any of the consolidated financial statements. Unfunded Commitments and Letters of Credit The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit and other commercial letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. The Company’s exposure to credit loss in the event of nonperformance by the other party to commitments to extend credit and standby letters of credit and other commercial letters of credit is represented by the contractual notional amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for extending loan facilities to customers. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable; inventory; property, plant and equipment; and income-producing properties. Commitments at December 31, 2016 and 2015 are summarized as follows: 2016 2015 (Dollars in thousands) Commitments to Fund Low Income Housing Partnership Investments $ 24,409 $ 14,909 Unused Credit Extensions 1,592,221 802,251 Standby Letters of Credit 63,753 45,083 Other Commercial Letters of Credit 52,125 36,256 $ 1,732,508 $ 898,499 Commitments and letters of credit generally have variable rates that are tied to the prime rate. The amount of fixed rate commitments is not considered material to this presentation. From time to time, the Company enters into certain types of contracts that contingently require the Company to indemnify parties against third party claims and other obligations customarily indemnified in the ordinary course of the Company’s business. The terms of such obligations vary, and, generally, a maximum obligation is not explicitly stated. Therefore, the overall maximum amount of the obligations cannot be reasonably estimated. The most significant of these contracts relate to certain agreements with the Company’s officers and directors under which the Company may be required to indemnify such persons for liabilities arising out of their employment relationship. Historically, the Company has not been obligated to make significant payments for these obligations, and no liabilities have been recorded for these obligations in its Consolidated Statements of Financial Condition as of December 31, 2016 and 2015 . Mortgage-Banking Derivatives Subsequent to the acquisition of Wilshire, the Company began to enter into various stand-alone mortgage-banking derivatives in order to hedge the risk associated with the fluctuation of interest rates. Changes in fair value are recorded as mortgage banking revenue. Residential mortgage loans funded with interest rate lock commitments and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. At December 31, 2016 , we had approximately $23.7 million in interest rate lock commitments and $13.0 million in total forward sales commitments for the future delivery of residential mortgage loans. There were no interest rate lock commitments or forward sales commitments at December 31, 2015 .

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS FASB ASC 820, Fair Value Measurements and Disclosures , 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 standard 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 other 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 estimates of assumptions that market participants would use in pricing the asset or liability. Securities Available for Sale The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The fair values of the Company’s Level 3 securities available for sale were measured using an income approach valuation technique. The primary inputs and assumptions used in the fair value measurement were derived from the securities’ underlying collateral which included discount rates, prepayment speeds, payment delays, and an assessment of the risk of default of the underlying collateral, among other factors. Significant increases or decreases in any of the inputs or assumptions would result in a significant increase or decrease in the fair value measurement. Impaired Loans The fair values of impaired loans are generally measured for impairment using the practical expedients permitted by FASB ASC 310-10-35 including impaired loans measured at an observable market price (if available), or at the fair value of the loan’s collateral (if the loan is collateral dependent). Fair value of the loan’s collateral, when the loan is dependent on collateral, is determined by appraisals or independent valuation, less costs to sell of 8.5%. For commercial and industrial and asset backed loans, independent valuations may include a 20-60% discount for accounts receivable and a 50-70% discount for inventory. These result in a Level 3 classification. Derivatives The fair value of our derivative financial instruments is based on derivative valuation models using market data inputs as of the valuation date that can generally be verified and do not typically involve significant management judgments. (Level 2 inputs). OREO OREO is fair valued at the time the loan is foreclosed upon and the asset is transferred to OREO. The value is based primarily on third party appraisals, less costs to sell of 8.5% and result in a Level 3 classification of the inputs for determining fair value. OREO is reviewed and evaluated on at least an annual basis for additional impairment and adjusted to lower of cost or market accordingly, based on the same factors identified above. Loans held for sale Loans held for sale are carried at the lower of cost or fair value, as determined by outstanding commitments from investors, or based on recent comparable sales (Level 2 inputs), if available, and if not available, are based on discounted cash flows using current market rates applied to the estimated life and credit risk (Level 3 inputs) or may be assessed based upon the fair value of the collateral which is obtained from recent real estate appraisals (Level 3 inputs). These appraisals may utilize a single valuation approach or a combination of approaches including 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 Level 3 classification of the inputs for determining fair value. Servicing Assets SBA and residential real estate loan servicing assets represent the value associated with servicing SBA and residential real estate loans that have been sold. The fair value for servicing assets is determined through discounted cash flow analysis and utilizes discount rates, prepayment speeds, and delinquency rate 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 servicing assets. The Company classifies loan servicing assets as recurring with Level 3 measurement inputs. Assets and liabilities measured at fair value on a recurring basis are summarized below: Fair Value Measurements at the End of the Reporting Period Using December 31, 2016 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (Dollars in thousands) Assets: Securities available for sale: U.S. Government agency and U.S. Government sponsored enterprises: GSE debt securities $ 12,008 $ — $ 12,008 $ — GSE collateralized mortgage obligations 705,667 — 705,667 — GSE mortgage-backed securities 728,041 — 728,041 — Corporate securities 11,127 — 11,127 — Municipal securities 86,839 — 85,700 1,139 Mutual funds 13,058 13,058 — — Servicing assets 26,457 — — 26,457 Interest rate swaps (1,565 ) — (1,565 ) — Mortgage banking derivatives 147 — 147 — Liabilities: Interest rate swaps (1,565 ) — (1,565 ) — Mortgage banking derivatives 41 — 41 — Fair Value Measurements at the End of the Reporting Period Using December 31, 2015 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (Dollars in thousands) Assets: Securities available for sale: U.S. Government agency and U.S. Government sponsored enterprises: GSE collateralized mortgage obligations $ 449,980 $ — $ 449,980 $ — GSE mortgage-backed securities 498,047 — 498,047 — Trust preferred security 3,749 — 3,749 — Municipal securities 45,511 — 44,345 1,166 Mutual funds 13,269 13,269 — — Servicing assets 12,000 — — 12,000 Interest rate swaps 2,860 — 2,860 — Liabilities: Interest rate swaps 2,860 — 2,860 — There were no transfers between Level 1, 2, and 3 during the period ended December 31, 2016 and 2015.

For fixed rate loans or deposits and for variable rate loans or deposits with infrequent repricing or repricing limits, fair value is based on discounted cash flows using current market rates applied to the estimated life and credit risk. The allowance for loan losses is considered to be a reasonable estimate of discount for credit quality concerns. Fair value of SBA loans held for sale is based on market quotes. For fair value of non-SBA loans held for sale, see the measurement method discussed previously. Fair value of time deposits and debt is based on current rates for similar financing. It was not practicable to determine the fair value of Federal Reserve Bank stock or FHLB stock due to restrictions placed on their transferability. The fair value of commitments to fund loans represents fees currently charged to enter into similar agreements with similar remaining maturities and is not presented herein. The fair value of these financial instruments is not material to the consolidated financial statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS The Company offers a loan hedging program to certain loan customers. Through this program, the Company originates a variable rate loan with the customer. The Company and the customer will then enter into a fixed interest rate swap. Lastly, an identical offsetting swap is entered into by the Company with a correspondent bank. These “back-to-back” swap arrangements are intended to offset each other and allow the Company to book a variable rate loan, while providing the customer with a contract for fixed interest payments. In these arrangements, the Company’s net cash flow is equal to the interest income received from the variable rate loan originated with the customer. These customer swaps are not designated as hedging instruments and are recorded at fair value in other assets and other liabilities. The changes in fair value are recognized in the income statement in other income and fees. At December 31, 2016, the following interest rate swaps related to our loan hedging program were outstanding: As of December 31, 2016 (Dollars in thousands) Interest rate swaps on loans with loan customers Notional amount $ 223,098 Weighted average remaining term 7.4 years Received fixed rate (weighted average) 4.29 % Pay variable rate (weighted average) 3.06 % Estimated fair value $ (1,565 ) Back to back interest rate swaps with correspondent banks Notional amount $ 223,098 Weighted average remaining term 7.4 years Received variable rate (weighted average) 3.06 % Pay fixed rate (weighted average) 4.29 % Estimated fair value $ 1,565 Subsequent to the acquisition of Wilshire, the Company began to enter into various stand-alone mortgage-banking derivatives in order to hedge the risk associated with the fluctuation of interest rates.

Total stockholders’ equity at December 31, 2016 was $1.86 billion , compared to $938.1 million at December 31, 2015. Warrants The Company assumed certain warrants (related to the TARP Capital Purchase Plan) to purchase shares of the Company’s common stock. On May 20, 2015, the U.S. Treasury Department completed an auction to sell certain of its warrant positions. The Company submitted the winning bid to repurchase an outstanding warrant to purchase 350,767 shares of the Company’s common stock and repurchased this warrant for $1.2 million . As of December 31, 2016, the U.S. Treasury Department held one remaining warrant for the purchase of 19,849 shares of the Company’s common stock.

Banking and Thrift [Abstract]
Regulatory Matters	REGULATORY MATTERS The Company and the Bank are subject to various regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and the Bank’s financial statements, such as restrictions on the growth, expansion or the payment of dividends or other capital distributions or management fees. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Prompt corrective action provisions are not applicable to bank holding companies. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum ratios (set forth in the table below) of common equity tier I, tier I, and total capital (as defined in the regulations) to risk-weighted assets (as defined) and of tier I capital (as defined) to average assets (as defined). Management believes that, as of December 31, 2016 and December 31, 2015 , the Company and the Bank met all capital adequacy requirements to which they are subject. As of December 31, 2016 and December 31, 2015 , the most recent regulatory notification categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum total risk-based, common equity tier I risk-based, tier I risk-based and tier I leverage ratios as set forth in the table below. There are no conditions or events since the notification that management believes have changed the Bank’s category.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE (“EPS”) Basic EPS does not reflect the possibility of dilution that could result from the issuance of additional shares of common stock upon exercise or conversion of outstanding securities, and is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if stock options or other contracts to issue common stock were exercised or converted to common stock that would then share in our earnings. For the years ended December 31, 2016 and 2015 , stock options and restricted shares awards for approximately 519 thousand and 553 thousand shares of common stock, respectively, were excluded in computing diluted earnings per common share because they were considered antidilutive. Additionally, warrants to purchase 19,849 and 19,276 of common stock (related to the TARP Capital Purchase Plan) were antidilutive and excluded for the year ended December 31, 2016 and 2015 , respectively. The following table shows the computation of basic and diluted EPS for the years ended December 31, 2016 , 2015 , and 2014 : Net income available to common stockholders (Numerator) Shares (Denominator) Per Share (Amount) (In thousands, except share and per share data) 2016 Basic EPS - common stock $ 113,747 103,289,059 $ 1.10 Effect of Dilutive Securities: Stock Options and Performance Units 241,259 Diluted EPS - common stock $ 113,747 103,530,318 $ 1.10 2015 Basic EPS - common stock $ 92,258 79,549,651 $ 1.16 Effect of Dilutive Securities: Stock Options and Performance Units 31,905 Common stock warrants 30,244 Diluted EPS - common stock $ 92,258 79,611,800 $ 1.16 2014 Basic EPS - common stock $ 88,615 79,493,742 $ 1.11 Effect of Dilutive Securities: Stock Options and Performance Units 38,896 Common stock warrants 78,399 Diluted EPS - common stock $ 88,615 79,611,037 $ 1.11

Transfers and Servicing [Abstract]
Servicing Assets	SERVICING ASSETS Servicing assets are recognized when SBA and residential mortgage loans are sold with servicing retained with the income statement effect recorded in gains on sales of loans. Servicing assets are initially recorded at fair value 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. The Company’s servicing costs approximates the industry average servicing costs of 40 basis points. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Management periodically evaluates servicing assets for impairment based upon the fair value of the rights as compared to the carrying amount. Impairment is determined by stratifying rights into groupings based on loan type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. The changes in net servicing assets for the year ended December 31, 2016 and 2015 were as follows: Year Ended December 31, 2016 2015 (Dollars in thousands) Balance at beginning of period $ 12,000 $ 10,341 Additions through originations of servicing assets 4,472 4,900 Additions through acquisition of Wilshire (net of servicing liabilities) 15,873 — Amortization and adjustments (5,888 ) (3,241 ) Balance at end of period $ 26,457 $ 12,000 Total servicing asset at December 31, 2016 totaled $26.5 million , and was comprised of $24.7 million in SBA servicing assets and $1.8 million in mortgage related servicing assets. At December 31, 2015 , servicing assets totaled $12.0 million , comprised of only SBA servicing assets. The Company utilizes the discounted cash flow method to calculate the initial excess servicing assets. The inputs used in determining the fair value of the servicing assets at December 31, 2016 and December 31, 2015 are presented below. December 31, 2016 December 31, 2015 Range Range SBA Servicing Assets: Weighted-average discount rate 5.55% ~ 9.85% 5.59% ~ 6.01% Constant prepayment rate 7.20% ~ 12.10% 7.30% ~ 11.90% Mortgage Servicing Assets: Weighted-average discount rate 7.00% ~ 7.25% N/A Constant prepayment rate 13.77% ~ 15.88% N/A

Summary of Significant Accoun29

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation— The accounting and reporting policies of the Company are in accordance with accounting principles generally accepted in the United States of America and conform to practices within the banking industry. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, principally the Bank.
Cash Flows	Cash Flows —Cash and cash equivalents include cash and due from banks, interest-earning deposits, federal funds sold and term federal funds sold, which have original maturities less than 90 days. The Company may be required to maintain reserve and clearing balances with the Federal Reserve Bank under the Federal Reserve Act. The reserve and clearing requirement balance was $0 at December 31, 2016 . Net cash flows are reported for customer loan and deposit transactions, deferred income taxes, and other assets and liabilities.
Securities	Securities— Securities are classified and accounted for as follows: (i) Securities that the Company has the positive intent and ability to hold to maturity are classified as “held to maturity” and reported at amortized cost. At December 31, 2016 and 2015 , we did not own securities in this category; (ii) Securities are classified as “available-for-sale” when they might be sold before maturity and are reported at fair value. Unrealized holding gains and losses are reported as a separate component of stockholders’ equity in accumulated other comprehensive income (loss), net of taxes. Accreted discounts and amortized premiums on securities are included in interest income using the interest method, and realized gains or losses related to sales of securities are calculated using the specific identification method, without anticipating prepayments, except for mortgage-backed securities where prepayments are expected. Management evaluates securities for other than temporary impairment (“OTTI”) at least on a quarterly basis and more frequently when economic conditions warrant such evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position 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: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI 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.
Derivative Financial Instruments and Hedging Transactions	Derivative Financial Instruments and Hedging Transactions —As part of our asset and liability management strategy, we may enter into derivative financial instruments, such as interest rate swaps, and caps and floors, with the overall goal of minimizing the impact of interest rate fluctuations on our net interest margin. The Company’s interest rate swaps and caps involve the exchange of fixed rate and variable rate interest payment obligations without the exchange of the underlying notional amounts and are therefore accounted for as stand alone derivatives. Changes in the fair value of the stand alone derivatives are reported in earnings as noninterest income. Residential mortgage loans funded with interest rate lock commitments and forward commitments for the future delivery of mortgage loans to third party investors, are both considered derivatives. The Company accounts for loan commitments related to the origination of mortgage loans that will be held-for-sale as derivatives at fair value on the balance sheet, with changes in fair value recorded in earnings. As part of the Company’s overall risk management, the Company’s Asset Liability Committee, which meets monthly, monitors and measures interest rate risk and the sensitivity of assets and liabilities to interest rate changes, including the impact of derivative transactions.
Loans	Loans— Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of any unearned interest, deferred loan fees and costs and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. Nonrefundable loan origination fees and certain direct origination costs are deferred and recognized in interest income using the level-yield method over the life of the loan. Interest on loans is credited to income as earned and is accrued only if deemed collectible. Generally, loans are placed on nonaccrual status and the accrual of interest is discontinued if principal or interest payments become 90 days past due and/or management deems the collectibility of the principal and/or interest to be in question. Loans to a customer whose financial condition has deteriorated are considered for nonaccrual status whether or not the loan is 90 days or more past due. Generally, payments received on nonaccrual loans are recorded as principal reductions. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Other loan fees and charges, representing service costs for the prepayment of loans, for delinquent payments or for miscellaneous loan services, are recorded as income when collected. Loans are categorized into risk categories based on relevant information about the ability of borrowers to service their debt, including, but not limited to, current financial information, historical payment experience, credit documentation, public information, and current economic trends. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes all non-homogeneous loans. This analysis is performed at least on a quarterly basis. The Company uses the following definitions for risk ratings: • Pass: Loans that meet a preponderance or more of the Company’s underwriting criteria and evidence an acceptable level of risk. • Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. • Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. • Doubtful/Loss: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or repayment in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Allowance for Loan Losses —The allowance for loan losses is a valuation allowance for probable incurred credit losses that are inherent in the loan portfolio. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers non-impaired loans and is based on historical loss experience adjusted for qualitative factors. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment. The Company further segregates these segments between loans accounted for under the amortized cost method (referred to as “Legacy Loans”) and acquired loans (referred to as “Acquired Loans”), as Acquired Loans were originally recorded at fair value with no carryover of the related allowance for loan losses. The historical loss experience for Legacy Loans is based on the actual loss history experienced by the Company. The loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. The following major portfolio segments have been identified: real estate loans (residential, commercial, and construction), commercial business loans, trade finance loans, and consumer/other loans. Due to the overall high level of real estate loans within the loan portfolio as a whole, as compared to other portfolio segments, for risk assessment and allowance purposes this segment was segregated into more granular pools by collateral property type. The Company uses a loan migration analysis which is a formula methodology based on the Bank’s actual historical net charge off experience for each loan class (type) pool and risk grade. The migration analysis is centered on the Bank’s internal credit risk rating system. The Company’s internal loan review and external contracted credit review examinations are used to determine and validate loan risk grades. This credit review system takes into consideration factors such as: borrower’s background and experience; historical and current financial condition; credit history and payment performance; economic conditions and their impact on various industries; type, fair value and volatility of the fair value of collateral; lien position; and the financial strength of any guarantors. A general loan loss allowance is provided on loans not specifically identified as impaired (“non-impaired loans”). The Bank’s general loan loss allowance has two components: quantitative and qualitative risk factors. The quantitative risk factors are based on a historical loss migration methodology. The loans are classified by class and risk grade and the historical loss migration is tracked for the various classes. Loss experience is quantified for a specified period and then weighted to place more significance to the most recent loss history. That loss experience is then applied to the stratified portfolio at each quarter end. Additionally, in order to systematically quantify the credit risk impact of other trends and changes within the loan portfolio, the Bank utilizes qualitative adjustments to the Migration Analysis within established parameters. The parameters for making adjustments are established under a Credit Risk Matrix that provides seven possible scenarios for each of the factors below. The matrix allows for up to three positive (major, moderate, and minor), three negative (major, moderate, and minor), and one neutral credit risk scenarios within each factor for each loan type pool. Generally, the factors are considered to have no significant impact (neutral) to our historical migration ratios. However, if information exists to warrant adjustment to the Migration Analysis, changes are made in accordance with the established parameters supported by narrative and/or statistical analysis. The Credit Risk Matrix and the nine possible scenarios enable the Bank to qualitatively adjust the Loss Migration Ratio by as much as 50 basis points in either direction (positive or negative) for each loan type pool. This matrix considers the following nine factors, which are patterned after the guidelines provided under the FFIEC Interagency Policy Statement on the Allowance for Loan and Lease Losses: • Changes in lending policies and procedures, including underwriting standards and collection, charge-off, and recovery practices. • Changes in national and local economic and business conditions and developments, including the condition of various market segments. • Changes in the nature and volume of the loan portfolio. • Changes in the experience, ability and depth of lending management and staff. • Changes in the trends of the volume and severity of past due loans, Classified Loans, nonaccrual loans, troubled debt restructurings and other loan modifications. • Changes in the quality of our loan review system and the degree of oversight by the Directors. • Changes in the value of underlying collateral for collateral-dependent loans. • The existence and effect of any concentrations of credit and changes in the level of such concentrations. • The effect of external factors, such as competition and legal and regulatory requirements, on the level of estimated losses in our loan portfolio. The Company also establishes specific loss allowances for loans where we have identified potential credit risk conditions or circumstances related to a specific individual credit. The specific allowance amounts are determined by a method prescribed by ASC 310-10-35-22, Measurement of Impairment . The loans identified as impaired will be accounted for in accordance with one of the three acceptable valuation methods: 1) the present value of future cash flows discounted at the loan’s effective interest rate; 2) the loan’s observable market price; or 3) the fair value of the collateral, if the loan is collateral dependent. For the collateral dependent impaired loans, we obtain a new appraisal to determine the amount of impairment as of the date that the loan became impaired. The appraisals are based on an “as is” valuation. To ensure that appraised values remain current, the Company either obtains updated appraisals every twelve months from a qualified independent appraiser or an internal re-valuation of the collateral is performed by qualified personnel. If the fair value of the collateral, less cost to sell, is less than the recorded amount of the loan, we then recognize impairment by creating or adjusting an existing valuation allowance with a corresponding charge to the provision for loan losses. If an impaired loan is expected to be collected through liquidation of the underlying collateral, the loan is deemed to be collateral dependent and the amount of impairment is charged off against the allowance for loan losses. The Bank considers a loan to be impaired when it is probable that not all amounts due (principal and interest) will be collectible in accordance with the contractual terms of the loan agreement. 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. The significance of payment delays and payment shortfalls is determined on a case-by-case basis by 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. For commercial business loans, real estate loans and certain consumer loans, the Company bases the measurement of loan impairment on the present value of the expected future cash flows, discounted at the loan’s effective interest rate or on the fair value of the loan’s collateral, less estimated costs to sell, if the loan is collateral dependent. Management evaluates most consumer loans for impairment on a collective basis because these loans generally have smaller balances and are homogeneous in the underwriting of terms and conditions and in the type of collateral. Impairment losses are included in the allowance for loan losses through a charge to the provision for loan losses. Upon disposition of an impaired loan, any unpaid balance is charged off to the allowance for loan losses. The allowance for loan losses for acquired credit impaired loans is based upon expected cash flows for these loans. To the extent that a deterioration in borrower credit quality results in a decrease in expected cash flows subsequent to the acquisition of the loans, an allowance for loan losses would be established based on management’s estimate of future credit losses over the remaining life of the loans. Acquired Loans —Loans that the Company acquires are recorded at fair value with no carryover of the related allowance for loan losses. On the date of acquisition, the Company considers acquired classified loans credit impaired loans (“Purchased Credit Impaired Loans” or “PCIs”) under the provisions of Accounting Standards Codification (“ASC”) 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality . On the date of acquisition, loans without credit impairment (“Acquired Performing Loans” or “Non-PCIs”) are not accounted for under ASC 310-30. Acquired loans are placed in pools with similar risk characteristics and recorded at fair value as of the acquisition date. For PCI loans, the cash flows expected to be received over the life of the pools were estimated by management with the assistance of a third party valuation specialist. These cash flows were utilized in calculating the carrying values of the pools and underlying loans, book yields, effective interest income and impairment, if any, based on actual and projected events. Default rates, loss severity and prepayment speed assumptions are periodically reassessed and updated within the accounting model to update the expectation of future cash flows. The excess of the cash expected to be collected over the pools’ carrying value is considered to be the accretable yield and is recognized as interest income over the estimated life of the loan or pool using the effective interest yield method. The accretable yield may change due to changes in the timing and amounts of expected cash flows. Changes in the accretable yield is disclosed quarterly. For PCI loans, the excess of the contractual balances due over the cash flows expected to be collected is considered to be nonaccretable difference. The nonaccretable difference represents our estimate of the credit losses expected to occur and was considered in determining the fair value of the loans as of the date of acquisition. Subsequent to the date of acquisition, any increases in expected cash flows over those expected at purchase date in excess of fair value are adjusted through the accretable difference on a prospective basis. Any subsequent decreases in expected cash flows over those expected at the acquisition date are recognized by recording a provision for loan losses that will maintain the original expected yield. PCI loans that met the criteria for nonaccrual of interest prior to the acquisition may be considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if management can reasonably estimate the timing and amount of the expected cash flows on such loans and if management expects to fully collect the new carrying value of the loans. As such, management may no longer consider the loan to be nonaccrual or nonperforming and may accrue interest on these loans, including the impact of any accretable discount. Management has determined that future cash flows are reasonably estimable on any such acquired loans that are past due 90 days or more and accruing interest. Management expects to fully collect the carrying value of the loans. Loans Held for Sale —Small Business Administration (“SBA”) and residential mortgage loans that the Company has the intent to sell prior to maturity have been designated as held for sale at origination and are recorded at the lower of cost or fair value, on an aggregate basis. A valuation allowance is established if the aggregate fair value of such loans is lower than their cost and charged to earnings. Gains or losses recognized upon the sale of loans are determined on a specific identification basis. Loan transfers are accounted for as sales when control over the loan has been surrendered. Control over such loans is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Company does not maintain control over the transferred assets through an agreement to repurchase them before their maturity. Loan Servicing Assets— The Company typically sells the guaranteed portion of SBA loans and retains the unguaranteed portion (“retained interest”). A portion of the premium on sale of SBA loans is recognized as gain on sale of loans at the time of the sale by allocating the carrying amount between the asset sold and the retained interest, including these servicing assets, based on their relative fair values. The remaining portion of the premium is recorded as a discount on the retained interest and is amortized over the remaining life of the loan as an adjustment to yield. The retained interest, net of any discount, are included in loans receivable—net of allowance for loan losses in the accompanying consolidated statements of financial condition. Servicing assets are recognized when SBA and residential mortgage loans are sold with servicing retained with the income statement effect recorded in gains on sales of loans. Servicing assets are initially recorded at fair value 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. The Company’s servicing costs approximates the industry average servicing costs of 40 basis points. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Management periodically evaluates servicing assets for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. No impairment charges were required in 2016 , 2015 , or 2014
FHLB Stock	FHLB Stock —The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB 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 as income.
Premises and Equipment	Premises and Equipment —Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization of premises and equipment are computed on the straight-line method over the following estimated useful lives:
OREO	OREO —OREO, which represents real estate acquired through foreclosure in satisfaction of commercial and real estate loans, is stated at fair value less estimated selling costs of the real estate. Loan balances in excess of the fair value of the real estate acquired at the date of acquisition are charged to the allowance for loan losses. Any subsequent operating expenses or income, reduction in estimated fair values, and gains or losses on disposition of such properties are charged or credited to current operations. For the year ended December 31, 2016 , the Company foreclosed on properties with an aggregate carrying value of $5.6 million and acquired $14.9 million in OREO from the acquisition of Wilshire. The Company recorded $2.2 million in valuation adjustments subsequent to the foreclosures, and the Company sold OREO properties for total proceeds of $17.4 million.
Goodwill and Intangible Assets	Goodwill and Intangible Assets— Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. In accordance with Accounting Standards Update (“ASU”) 2011-08, Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment , the Company makes a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying the two-step goodwill impairment test. If management concludes that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, the two-step impairment test is bypassed. Goodwill is also tested for impairment on an interim basis if circumstances change or an event occurs between annual tests that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions and selecting an appropriate control premium. The selection and weighting of the various fair value techniques may result in a higher or lower fair value. Judgment is applied in determining the weighting that is most representative of fair value. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Core deposit intangibles are amortized over a seven to 10 year period.
Stock-Based Compensation	Stock-Based Compensation— Compensation cost is recognized for 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, 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	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 income tax assets and liabilities represent the tax effects, based on current tax law, of future deductible or taxable amounts attributable to events that have been recognized in the financial statements. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, the projected future taxable income and tax planning strategies in making this assessment. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and / or penalties related to income tax matters in income tax expense. Section 382 of the Internal Revenue Code imposes a limitation (“382 Limitation”) on a corporation’s ability to use any net unrealized built in losses and other tax attributes, such as net operating loss and tax credit carryforwards, when it undergoes a 50% ownership change over a designated testing period not to exceed three years (“382 Ownership Change”). As a result of the acquisitions on February 14, 2013 of PIB, on August 12, 2013 of Foster, and on July 29, 2016 of Wilshire Bancorp, all three entities underwent a 382 Ownership Change resulting in a 382 Limitation to each entity’s net operating loss and tax credit carryforwards. None of the entities had a net unrealized built in loss as of the 382 Ownership Change date. Given the applicable 382 Limitation, the Company is expected to fully utilized the PIB and Wilshire net operating loss and tax credit carryforwards before expiration. However, future transactions, such as issuances of common stock or sales of shares of our stock by certain holders of our shares, including persons who have held, currently hold or may accumulate in the future 5% or more of our outstanding common stock for their own account, could trigger a future Section 382 Ownership Change of the Company which could limit the Company’s use of these tax attributes
Earnings per Common Share	Earnings per Common Share —Basic Earnings per Common Share is computed by dividing net income (loss) available to common stockholders by the weighted-average number of common shares outstanding for the period. Allocated ESOP shares are considered outstanding for this calculation. Diluted Earnings per Common Share reflects the potential dilution of securities that could share in the earnings of the Company. Earnings and dividends per share are restated for all stock splits and stock dividends through the date of issuance of the financial statements.
Equity	Equity —The Company accrues for common stock dividends as declared. Common stock dividends of $42.5 million and $33.4 million , were paid in 2016 and 2015 , respectively. There were no common stock dividends declared but unpaid at December 31, 2016 and 2015 .
BOLI	BOLI —The Company has purchased life insurance policies on certain key executives and directors. 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.
Investments in Affordable Housing Partnerships	Investments in Affordable Housing Partnerships —
Comprehensive Income	Comprehensive (Loss) Income —Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on securities available for sale and interest-only strips which are also recognized as separate components of stockholders’ equity, net of tax.
Loss Contingencies and Loan Commitments and Related Financial Instruments	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 believes there are no such matters that would have a material effect on the consolidated financial statements as of December 31, 2016 or 2015 . Accrued loss contingencies for all legal claims totaled approximately $557 thousand at December 31, 2016 . There were no accrued loss contingencies for legal claims December 31, 2015 . 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. See Note 14 Commitments and Contingencies of the Notes to Consolidated Financial Statements for further discussion
Fair Values of Financial Instruments	Fair Values of Financial Instruments —Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets— The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. If the estimated future cash flows (undiscounted) over the remaining useful life of the asset are less than the carrying value, an impairment loss would be recorded to reduce the related asset to its estimated fair value.
Transfers of Financial Assets	Transfer of Financial Assets —Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Use of Estimates in the Preparation of Consolidated Financial Statements	Use of Estimates in the Preparation of Consolidated Financial Statements —The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from those estimates. Material estimates that are susceptible to change in the near term relate to the determination of the allowance and provision for loan losses, the evaluation of other than temporary impairment of investment securities, determining the fair value of derivatives and hedging activities, determining the carrying value for cash surrender value of life insurance, carrying value of goodwill and other intangible assets, accounting for deferred tax assets and related valuation allowances, the determination of the fair values of investment securities and other financial instruments, determination of the fair values of other real estate owned, accounting for PCI loans, accounting for FDIC receivable, accounting for lease arrangements, accounting for incentive compensation, profit sharing and bonus payments and the valuation of servicing assets.
Reclassifications	Reclassifications -
Recent Accounting Pronouncements and Newly Issued But Not Yet Effective Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers which supersedes the revenue recognition requirements in Topic 605, Revenue Recognition.” ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts. ASU 2014-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those years, using a retrospective application approach. The adoption of ASU 2014-09 did not have a significant impact on the Company’s consolidated financial statements. In June 2015, the FASB issued ASU 2015-10, “Technical Corrections and Improvements.” The amendments in ASU 2015-10 represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have significant effect on current accounting practice or create a significant administrative cost to most entities. The amendments that require transition guidance are effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2015. The adoption of ASU 2015-10 did not have a significant impact on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805).” The guidance requires an acquirer in a business combination to recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments also require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the estimated amounts, calculated as if the accounting had been completed at the acquisition date. The amendments become effective for fiscal years beginning after December 15, 2015. The adoption of ASU 2015-10 did not have a significant impact on the Company’s consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments require 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. The new guidance becomes effective for fiscal years beginning after December 15, 2017. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases.” The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-05, “Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships (ASU 2016-05)”. ASU 2016-05 clarifies that a change in the counterparty to a derivative instrument (a novation) that has been designated as the hedging instrument does not, in and of itself, require designation of that hedging relationship provided that all other hedge accounting criteria continue to be met. Public business entities have the option to apply this ASU on a prospective basis or a modified retrospective basis. It is effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. The adoption of ASU 2016-05 did not have a significant impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU 2016-07, “Investments-Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting”. ASU 2016-07 no longer requires an investor to retroactively adjust the investment and record for periods as if that the investment had been held, but did not qualify for the equity method of accounting. Under ASU 2016-07 the equity method is only applied to the investment from the date that it qualifies. When an investment qualifies for equity method accounting, the investor should add the cost of acquiring the additional interest in the investee to the current basis of the investor’s existing interest and recognize in earnings the unrealized holding gain or loss in accumulated other comprehensive income, if the existing investment was accounted for as an available-for-sale equity security. ASU 2016-07 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and early adoption is permitted. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “ASU 2016-09, Compensation- Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”. ASU 2016-09 includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. The areas for simplification include income tax consequences, forfeitures, classification of awards as either equity or liabilities and classification on the statement of cash flows. This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2016 and early adoption is permitted for financial statements that have not been previously issued. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard 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.” ASU 2016-12 provides clarity and simplification to the transition guidance from the previously issued ASU 2014-09. The amendment provides narrow scope improvements to assessing the collectability criterion, the presentation of sales and other similar taxes, non-cash consideration, contract modifications, completed contracts, and technical corrections. ASU 2106-12 becomes effective for annual periods, and interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. ASU 2016-13 becomes effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” ASU 2016-15 provides guidance on classification and presentation of certain cash receipts and cash payments on an institution’s statement of cash flows. The amendment aims to reduce the diversity in practice with respects to certain types of cash flows. ASU 2016-15 becomes effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, “Intangibles: Goodwill and Other: Simplifying the Test for Goodwill Impairment.” ASU 2017-04 will amend and simplify current goodwill impairment testing to eliminate Step 2 from the current provisions. Under the new guidance, an entity should perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying value and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. An entity still has the option to perform the quantitative assessment for a reporting unit to determine if a quantitative impairment test is necessary. ASU 2017-04 should be adopted for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements.
Fair Value Measurements	Securities Available for Sale The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The fair values of the Company’s Level 3 securities available for sale were measured using an income approach valuation technique. The primary inputs and assumptions used in the fair value measurement were derived from the securities’ underlying collateral which included discount rates, prepayment speeds, payment delays, and an assessment of the risk of default of the underlying collateral, among other factors. Significant increases or decreases in any of the inputs or assumptions would result in a significant increase or decrease in the fair value measurement. Impaired Loans The fair values of impaired loans are generally measured for impairment using the practical expedients permitted by FASB ASC 310-10-35 including impaired loans measured at an observable market price (if available), or at the fair value of the loan’s collateral (if the loan is collateral dependent). Fair value of the loan’s collateral, when the loan is dependent on collateral, is determined by appraisals or independent valuation, less costs to sell of 8.5%. For commercial and industrial and asset backed loans, independent valuations may include a 20-60% discount for accounts receivable and a 50-70% discount for inventory. These result in a Level 3 classification. Derivatives The fair value of our derivative financial instruments is based on derivative valuation models using market data inputs as of the valuation date that can generally be verified and do not typically involve significant management judgments. (Level 2 inputs). OREO OREO is fair valued at the time the loan is foreclosed upon and the asset is transferred to OREO. The value is based primarily on third party appraisals, less costs to sell of 8.5% and result in a Level 3 classification of the inputs for determining fair value. OREO is reviewed and evaluated on at least an annual basis for additional impairment and adjusted to lower of cost or market accordingly, based on the same factors identified above. Loans held for sale Loans held for sale are carried at the lower of cost or fair value, as determined by outstanding commitments from investors, or based on recent comparable sales (Level 2 inputs), if available, and if not available, are based on discounted cash flows using current market rates applied to the estimated life and credit risk (Level 3 inputs) or may be assessed based upon the fair value of the collateral which is obtained from recent real estate appraisals (Level 3 inputs). These appraisals may utilize a single valuation approach or a combination of approaches including 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 Level 3 classification of the inputs for determining fair value.
