Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Nature of Operations— BBCN Bancorp, Inc. ("BBCN Bancorp" on a parent-only basis and the "Company" on a consolidated basis), headquartered in Los Angeles, California, is the holding company for BBCN Bank ("BBCN Bank" or the "Bank"). The Bank has branches in California, New Jersey, and the New York City, Chicago, Seattle and Washington, D.C. metropolitan areas, as well as loan production offices in Atlanta, Dallas, Denver, Northern California, Seattle and Annandale. BBCN 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, 2014. Net cash flows are reported for customer loan and deposit transactions, deferred income taxes and other assets and liabilities.
	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, 2014 and 2013, 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—As part of our asset and liability management strategy, we may enter into derivative financial instruments, such as interest rate swaps, 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. 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 FASB 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 ACILs 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 all acquired classified loans credit impaired loans ("Acquired Credit Impaired Loans" or "ACILs") under the provisions of Accounting Standards Codification ("ASC") 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. On the date of acquisition, acquired Pass graded loans ("Acquired Performing Loans" or "APLs") 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 ACILs, 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 will change due to changes in the timing and amounts of expected cash flows. Changes in the accretable yield is disclosed quarterly.
	For ACILs, 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.
	ACILs 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”) 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. SBA 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, 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 loans are sold with servicing retained with the income statement effect recorded in gains on sales of SBA 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 2014, 2013, or 2012.
	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.
	FDIC Loss Share Receivable—In conjunction with the FDIC-assisted acquisition of Innovative Bank, the Company entered into shared-loss agreements with the FDIC for amounts receivable covered by the shared-loss agreements. The Company elected to account for amounts receivable under the loss sharing agreement with the FDIC as FDIC loss share receivable in accordance with ASC 805. The FDIC loss share receivable was recorded at fair value, based on the discounted value of expected future cash flows under the loss sharing agreement. The cash flows expected to be received under the loss agreement were estimated by management with the assistance of a third party valuation specialist. The difference between the present value and the undiscounted cash flows we expect to collect from the FDIC will be accreted into noninterest income over the life of the FDIC loss share receivable.
	The FDIC loss share receivable is reviewed quarterly and adjusted for any changes in expected cash flows based on recent performance and expectations for future performance of the covered portfolio. These adjustments are measured on the same basis as the related covered loans and covered other real estate owned. Any increases in the cash flows of the covered assets over those expected will reduce the FDIC loss share receivable and any decreases in cash flows of the covered assets under those expected will increase the FDIC loss share receivable. Increase and decrease to the FDIC loss share receivable are recorded as adjustments to noninterest income.
	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.
Section 382 of the Internal Revenue Code imposes limitations 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). As a result of the acquisition on February 14, 2013 of Pacific International Bancorp Inc. ("PIB") and on August 12, 2013 of Foster Bankshares Inc. ("Foster"), both PIB and Foster underwent a greater than 50% ownership change. Except for the limitation on PIB's net operating loss carryforward, there is expected to be no limitation on the use of either PIB’s or Foster’s tax attributes because neither company has a net unrealized built in loss. PIB is expected to fully utilized the net operating loss carryforward before it expires with the application of the annual limitation. 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 future Section 382 limitations on the Company's use of tax attributes.
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—The Company accrues for common stock dividends as declared. Common stock dividends of $27.8 million and $19.7 million were paid in 2014 and 2013. There were no common stock dividends declared but unpaid at December 31, 2014 and 2013. Accrued preferred and common stock dividends are included in other liabilities.
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—The Company owns limited partnerships interest in projects of affordable housing for lower income tenants. The investments in which the Company has significant influence are recorded using the equity method of accounting. For those investments in limited partnerships for which the Company does not have a significant influence, such investments are accounted for using the cost method of accounting and the annual amortization is based on the proportion of tax credits received in the current year to the total estimated tax credits to be allocated to the Company.
Comprehensive 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, cash flow hedges, and interest-only strips which are also recognized as separate components of stockholders’ equity, net of tax.
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, 2014 or 2013.
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 13 Commitments and Contingencies of the Notes to Consolidated Financial Statements for further discussion.
Allowance for Unfunded Commitments—The allowance for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to these unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. The allowance for unfunded commitments is included in other liabilities on the consolidated balance sheets, with changes to the balance charged against noninterest expense.
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—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.
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—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 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, accounting for 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 ACILs, accounting for FDIC receivable, accounting for lease arrangements, accounting for incentive compensation, profit sharing and bonus payments and the valuation of servicing assets.
Reclassifications—Some items in the prior year financial statements were reclassified to conform to the current presentation.
Recently Issued Accounting Pronouncements
FASB ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The provisions of ASU No. 2013-11 require an entity to present an unrecognized tax benefit, or portion thereof, in the statement of financial position as a reduction to adeferred tax asset for a net operating loss carryforward or a tax credit carryforward, with certain exceptions related to availability. ASU No. 2013-11 is effective for interim and annual reporting periods beginning after December 15, 2013. The adoption of ASU No. 2013-11 did not have a material impact on the Company's consolidated financial statements.
FASB ASU No. 2014-01, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. These amendments permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Disclosures for a change in accounting principle are required upon transition. ASU 2014-01 is effective for for interim and annual periods beginning after December 15, 2014 and is not expected to have a significant impact on the Company's financial statements.
FASB ASU No. 2014-04, Receivables—Troubled Debt Restructuring by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure. The amendment intends to clarify the terms defining when an in substance foreclosure occurs, which determines when the receivable should be derecognized and the real estate property recognized. ASU No. 2014-04 will be effective for interim and annual periods beginning after December 31, 2014. ASU No. 2014-04 is not expected to have a material impact on the Company's consolidated financial statements.
FASB ASU No. 2014-12, Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The amendments in ASU 2014-12 require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The performance target should not be reflected in estimating the grant date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. ASU 2014-12 is effective for interim and annual periods beginning after December 31, 2014 and is not expected to have a significant impact on the Company's financial statements.
FASB ASU No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. The amendments in ASU 2014-15 defines management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and provide related disclosures. Currently, GAAP does not provide guidance to evaluate whether there is substantial doubt about the organization’s ability to continue as a going concern. Guidance is provided to an organization’s management, with principles and definitions to reduce diversity in the timing and content of disclosures commonly provided by organizations today in the financial statements footnotes. ASU 2014-15 is effective for interim and annual periods ending after December 15,
2016 and is not expected to have an impact on the Company's financial statements.

	The bargain purchase gain from the PIB acquisition was recorded in other income in the Consolidated Statements of Income.
	Acquired Loans
	The Company estimated the fair value for most loans acquired by utilizing a methodology wherein loans with comparable characteristics were aggregated by type of collateral, remaining maturity and repricing terms. Cash flows for each pool were determined by estimating future credit losses and prepayment rates. Projected monthly cash flows were then discounted using a risk-adjusted market rate for similar loans to determine the fair value of each pool. To estimate the fair value of the remaining loans, management analyzed the value of the underlying collateral of the loans, assuming the fair values of the loans were derived from the eventual sale of the collateral. The value of the collateral was based on recently completed appraisals adjusted to the valuation date based on recognized industry indices. The Company discounted those values using market derived rates of return, with consideration given to the period of time and costs associated with the foreclosure and disposition of the collateral. There was no carryover of the allowance for loan losses associated with the loans the Company acquired as the loans were initially recorded at fair value. The following table presents loans acquired with deteriorated credit quality as of the date of acquisition:
		Foster				PIB
		(In thousands)
	Contractually required principal and interest at acquisition	$	150,430			$	54,462
	Contractual cash flows not expected to be collected (nonaccretable discount)	37,447				9,687
	Expected cash flows at acquisition	112,983				44,775
	Interest component of expected cash flows (accretable discount)	14,928				4,945
Fair value of acquired impaired loans	$	98,055			$	39,830
The outstanding principal balances and the related carrying amounts of the acquired loans included in the statement of financial condition are $188.1 million and $153.9 million, respectively for Foster and $75.3 million and $64.9 million, respectively for PIB, as of December 31, 2014.
Pro Forma Information
The operating results of Foster and PIB from the dates of acquisitions through December 31, 2013 are included in the Condensed Consolidated Statement of Income for 2013 and are not material to the total consolidated operating results for the year ended December 31, 2013.
The following unaudited combined pro forma information presents the operating results for the year ended December 31, 2013, as if the Foster and PIB acquisitions had occurred on January 1, 2013:

Net Interest income	$	263,737
Net income	$	78,155
Pro forma earnings per share:

The above pro forma results are presented for illustrative purposes and are not intended to represent or be indicative of the actual results of operations of the merged companies that would have been achieved had the acquisition occurred at January 1, 2013, nor are they intended to represent or be indicative of future results of operations. The pro forma results do not include expected operating cost savings as a result of the acquisitions. These pro forma results require significant estimates and judgments particularly as it relates to valuation and accretion of income associated with acquired loans.
Acquisition-Related Expenses
The Company incurred acquisition-related expenses associated with the Foster and PIB acquisitions which were reflected on the Company's income statement. During the year ended December 31, 2014, the Company incurred $264 thousand and $58 thousand in expenses related to the Foster and PIB acquisitions, respectively. During the year ended December 31, 2013, the Company incurred $4.0 million and $1.1 million in expenses related to the Foster and PIB acquisitions, respectively.

The Company evaluates securities for OTTI on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. 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, 2014. The trust preferred securities in a continuous loss position for twelve months or longer had an unrealized loss of $544 thousand at December 31, 2014 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 and mortgage-backed securities in a continuous loss position for twelve months or longer had an unrealized loss of $3.0 million and $1.4 million, respectively, at December 31, 2014. 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, 2014.
The Company considers the losses on our investments in unrealized loss positions at December 31, 2014 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.

Loans Receivable and Allowance for Loan Losses	LOANS RECEIVABLE AND THE ALLOWANCE FOR LOAN LOSSES
	The following is a summary of loans by major category at December 31, 2014 and 2013:
		December 31, 2014			December 31, 2013
		(In thousands)
	Loan portfolio composition
	Real estate loans:

	Gross loans receivable	5,565,192			5,074,175
	Less: allowance for loan losses	(67,758		)	(67,320		)
	Loans receivable, net	$	5,497,434		$	5,006,855
	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 ACILs and APLs.
	The following table presents changes in the accretable discount on the ACILs for the years ended December 31, 2014 and 2013:
		Year Ended December 31,
		2014			2013
	Balance at beginning of period	$	47,398		$	18,652
	Additions due to mergers and acquisitions	—			19,873
	Accretion	(16,222		)	(15,590		)
	Changes in expected cash flows	(7,125		)	24,463
	Balance at end of period	$	24,051		$	47,398
	On the acquisition date, the amount by which the undiscounted expected cash flows exceed the estimated fair value of the ACILs 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 will change 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 ACILs may change; and 3) estimates of the amount of the contractual principal and interest that will not be collected (nonaccretable difference) may change.
	The following tables detail the activity in the allowance for loan losses by portfolio segment for the year ended December 31, 2014 and 2013:

(1)	The Acquired Loans exclude ACILs.
(2)	Nonaccrual loans exclude the guaranteed portion of delinquent SBA loans that are in liquidation totaling $27.5 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, ACILs 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.

Under certain circumstances, the Company provides borrowers relief through loan modifications. These modifications are either temporary in nature (“temporary modifications”) or are more substantive. At December 31, 2014, total modified loans were $76.1 million, compared to $58.9 million at December 31, 2013. 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.

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, 2014 were comprised of 24 commercial real estate loans totaling $28.1 million, 30 commercial business loans totaling $25.6 million and 3 consumer and other loans totaling $3.4 million. TDRs on accrual status at December 31, 2013 were comprised of 15 commercial real estate loans totaling $21.3 million, 28 commercial business loans totaling $12.1 million, and 2 consumer loans totaling $535 thousand. TDRs on accrual status at December 31, 2012 were comprised of 12 commercial real estate loans totaling $23.6 million and 20 commercial business loans totaling $5.8 million. Management expects that the TDRs on accrual status as of December 31, 2014, 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 $5.7 million, $6.6 million, and $6.3 million of specific reserves to TDRs as of December 31, 2014, 2013, and 2012 respectively. As of December 31, 2014, 2013, and 2012 the Company did not have any outstanding commitments to extend additional funds to these borrowers.

Subordinated Debentures

SUBORDINATED DEBENTURES

At December 31, 2014, the Company had five wholly-owned subsidiary grantor trusts that had issued $46 million of pooled Trust Preferred Securities (“trust preferred securities”). Upon the acquisition of PIB, the Company assumed one grantor trust established by former PIB which issued $4 million of trust preferred securities, which the Company redeemed on June 17, 2013. Upon the acquisition of Foster, the Company assumed one grantor trust established by former Foster which issued $15 million of trust preferred securities, which the Company redeemed on March 17, 2014. 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 BBCN Bancorp. The Debentures are the sole assets of the trusts. BBCN Bancorp’s obligations under the subordinated debentures and related documents, taken together, constitute a full and unconditional guarantee by BBCN Bancorp 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. BBCN Bancorp 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. BBCN Bancorp also has a right to defer consecutive payments of interest on the debentures for up to five years.

The Center Capital Trust I trust preferred security has a remaining discount of $5.3 million at December 31, 2014 and the effective rate of the security, including the effect of the discount accretion, was 5.54% at December 31, 2014.

The Company’s investment in the common trust securities of the issuer trusts of $1.6 million and $1.9 million at December 31, 2014 and December 31, 2013, respectively, is included in other assets. Although the subordinated debt issued by the trusts are not included as a component of stockholders' equity in the consolidated balance sheets, the debt is treated as capital for regulatory purposes. The trust preferred security debt issuances are includable in Tier I capital up to a maximum of 25% of capital on an aggregate basis. Any amount that exceeds 25% qualifies as Tier 2 capital. At December 31, 2014, $40.7 million of the trusts’ securities qualified as Tier 1 capital. In July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) was signed into law which, among other things, limits the ability of bank holding companies with total assets of more than $15 billion to treat trust preferred security debt issuances as Tier 1 capital. Since the Company had less than $15 billion in assets at December 31, 2014, we will be able to continue to include its existing trust preferred securities in Tier 1 capital under the Dodd-Frank Act.

	Net deferred tax assets:	$	63,023			$	89,297
	Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are 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, 2014 and 2013.

The Company and its subsidiaries are subject to U.S. federal income tax as well as income tax of the state of California and various other state income taxes. The statute of limitations related to the consolidated Federal income tax return is closed for all tax years up to and including 2010. The expiration of the statute of limitations related to the various state income tax returns that the Company and subsidiaries file, varies by state. The Company is currently under examination by the Internal Revenue Service (“IRS”) for the 2011 tax year and by the California Franchise Tax Board for the 2009 and 2010 tax years. While the outcomes of the examinations are unknown, the Company expects no material adjustments.
A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2014 and 2013 is as follows:
	2014				2013
	(In thousands)
Balance at January 1,	$	1,289			$	748

Additions based on taxing authority examination	—				997
Settlements with taxing authorities	—				(997		)
Balance at December 31,	$	1,816			$	1,289
The total amount of unrecognized tax benefits was $1.8 million at December 31, 2014 and $1.3 million at December 31, 2013 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 $1.2 million and $872 thousand at December 31, 2014 and 2013, respectively. The amount of unrecognized tax benefits increased due to an additional accrual of $527 thousand for prior year tax positions. The Company expects the total amount of unrecognized tax benefits to decrease by $216 thousand within the next twelve months due to the settlement with the state authority.
The Company recognizes interest and penalties related to income tax matters in income tax expense. The Company had approximately $96 thousand and $58 thousand for interest and penalties accrued at December 31, 2014 and 2013, respectively.

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 Company has another stock-based incentive plan, the 2006 Stock Incentive Plan, adopted April 12, 2006, as amended and restated June 13, 2007 (the "2006 Plan"). The 2006 Plan provides for the granting of incentive stock options to officers and employees, and non-qualified stock options and restricted stock awards to employees (including officers) and non-employee directors. The option prices of all options granted under the 2006 Plan must be not less than 100% of the fair market value at the date of grant. All options granted generally vest at the rate of 20% per year except that the options granted to the non-employee directors vest at the rate of 33% per year. All options not exercised generally expire ten years after the date of grant.
	Under the 2007 and 2006 plans 2,504,172 shares were available for future grants as of December 31, 2014.
	The total shares reserved for issuance will serve as the underlying value for all equity awards under the 2007 Plan and the 2006 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 by delivering the appropriate number of shares. For the year ended December 31, 2014, 66,000 shares of restricted and performance unit awards were granted under the 2007 and 2006 Plans. The fair value of performance unit awards granted is the fair market value of the Company’s common stock on the date of grant. In 2014, 2013 and 2012, 210,000, 0, and 0 options were granted, respectively.
	The following is a summary of stock option activity under the 2007 and 2006 Plans for the year ended 2014:

Employee_Benefit_Plans

Employee Benefit Plans	12 Months Ended

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, 2014 and 2013 amounted to $1.2 million and $1.3 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 $28 thousand, $31 thousand and $37 thousand for 2014, 2013 and 2012, 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 one NEO is currently participating in the LTIP. The Company accrued $228 thousand, $180 thousand, and $90 thousand in 2014, 2013, and 2012 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 $1.9 million, $1.6 million and $1.3 million for 2014, 2013 and 2012, respectively.
	Employees Stock Ownership Plan (“ESOP”)—The Company established an ESOP, which is open to all eligible employees who have completed one year of service working at least 1,000 hours. The Company’s contributions to the ESOP represent an annual profit-sharing bonus paid to employees. Such contributions and available forfeitures are allocated to active employees based on the percentage that their compensation represents of the total compensation of eligible employees. The Company purchased 0, 20,081 and 0 shares of its common stock for the ESOP in 2014, 2013 and 2012, respectively. The Company’s contribution and expense to the ESOP was approximately $25 thousand, $57 thousand and $250 thousand for 2014, 2013 and 2012, respectively. As of December 31, 2014 and 2013, the ESOP held 6,888 and 160,938 shares, and there were no unallocated shares. On an annual basis, the Board determines the amount to contribute to the ESOP as a profit sharing bonus.
	Upon termination, plan participants are paid in cash or retain their vested balance in the ESOP. During 2014, 2013 and 2012, shares withdrawn from the ESOP amounted to 152,192, 9,354 and 1,903 shares, respectively. During 2014, 2013 and 2012, no shares were added to the ESOP plan from dividend reinvestments. Effective September 30, 2014, the Company terminated the ESOP and no further contributions were made and no new participants allowed in to the plan as of the termination date.

	Operating lease expense recorded under such leases in 2014, 2013 and 2012 amounted to approximately $11.6 million, $10.6 million and $9.0 million, respectively.
	Legal contigencies
	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, 2014, and has taken into consideration the views of such counsel as to the outcome of the claims. In management’s opinion, the final disposition of all such claims will not have a material adverse effect on the consolidated financial condition, results of operations or cash flows of the Company. As of December 31, 2014 and 2013, the Company recorded an accrued liability of $0 and $0, respectively, for litigation settlements.
	Unfunded Committments 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, 2014 and 2013 are summarized as follows:
		2014		2013
		(In thousands)
	Commitments to extend credit	$	586,714	$	668,306
	Standby letters of credit	41,987		44,190
	Other commercial letters of credit	37,439		56,380
		$	666,140	$	768,876
	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 on its consolidated statements of financial condition as of December 31, 2014 and 2013.

Fair_Value_Measurements

Fair Value Measurements	12 Months Ended

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 and result in a Level 2 classification.
	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 and result in a Level 2 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.
	Assets and liabilities measured at fair value on a recurring basis are summarized below:

The methods and assumptions used to estimate fair value are described as follows.
The carrying amount is the estimated fair value for cash and cash equivalents, savings and other interest bearing demand deposits, customer’s and Bank’s liabilities on acceptances, noninterest bearing deposits, short-term debt, secured borrowings, and variable rate loans or deposits that reprice frequently and fully. 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 Federal Home Loan Bank 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.

As of December 31, 2014, a warrant held by the U.S. Treasury Department for the purchase of 347,165 shares of the Company's common stock remains outstanding.
	In conjunction with the acquisition of PIB, the Company assumed a warrant (related to the TARP Capital Purchase Plan) to purchase shares of its common stock. At the acquisition date, the warrants were canceled and converted into a warrant to purchase BBCN Bancorp common stock which expires on December 12, 2018. As of December 31, 2014, the U.S. Treasury Department held the warrant for the purchase of 18,745 shares of the Company's common stock.

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, 2014 and 2013, stock options and restricted shares awards for approximately 494 thousand and 147 thousand shares of common stock, respectively, were excluded in computing diluted earnings per common share because they were antidilutive. Additionally, warrants to purchase 18,745 and 18,298 of common stock (related to the TARP Capital Purchase Plan) were antidilutive and excluded for the year ended December 31, 2014 and 2013, respectively.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
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, 2014. 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, 2014 and 2013, 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, 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. 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 FASB 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 ACILs 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 all acquired classified loans credit impaired loans ("Acquired Credit Impaired Loans" or "ACILs") under the provisions of Accounting Standards Codification ("ASC") 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. On the date of acquisition, acquired Pass graded loans ("Acquired Performing Loans" or "APLs") 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 ACILs, 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 will change due to changes in the timing and amounts of expected cash flows. Changes in the accretable yield is disclosed quarterly.
	For ACILs, 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.
	ACILs 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”) 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. SBA 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, 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 loans are sold with servicing retained with the income statement effect recorded in gains on sales of SBA 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 2014, 2013, or 2012
Allowance for Loan Losses
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.
FDIC Loss Share Receivable	FDIC Loss Share Receivable—In conjunction with the FDIC-assisted acquisition of Innovative Bank, the Company entered into shared-loss agreements with the FDIC for amounts receivable covered by the shared-loss agreements. The Company elected to account for amounts receivable under the loss sharing agreement with the FDIC as FDIC loss share receivable in accordance with ASC 805. The FDIC loss share receivable was recorded at fair value, based on the discounted value of expected future cash flows under the loss sharing agreement. The cash flows expected to be received under the loss agreement were estimated by management with the assistance of a third party valuation specialist. The difference between the present value and the undiscounted cash flows we expect to collect from the FDIC will be accreted into noninterest income over the life of the FDIC loss share receivable.
	The FDIC loss share receivable is reviewed quarterly and adjusted for any changes in expected cash flows based on recent performance and expectations for future performance of the covered portfolio. These adjustments are measured on the same basis as the related covered loans and covered other real estate owned. Any increases in the cash flows of the covered assets over those expected will reduce the FDIC loss share receivable and any decreases in cash flows of the covered assets under those expected will increase the FDIC loss share receivable. Increase and decrease to the FDIC loss share receivable are recorded as adjustments to noninterest income
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 limitations 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). As a result of the acquisition on February 14, 2013 of Pacific International Bancorp Inc. ("PIB") and on August 12, 2013 of Foster Bankshares Inc. ("Foster"), both PIB and Foster underwent a greater than 50% ownership change. Except for the limitation on PIB's net operating loss carryforward, there is expected to be no limitation on the use of either PIB’s or Foster’s tax attributes because neither company has a net unrealized built in loss. PIB is expected to fully utilized the net operating loss carryforward before it expires with the application of the annual limitation. 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 future Section 382 limitations on the Company's use of tax attributes
Employee Stock Ownership Plan (ESOP)	.
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 $27.8 million and $19.7 million were paid in 2014 and 2013. There were no common stock dividends declared but unpaid at December 31, 2014 and 2013. Accrued preferred and common stock dividends are included in other liabilities.
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—The Company owns limited partnerships interest in projects of affordable housing for lower income tenants. The investments in which the Company has significant influence are recorded using the equity method of accounting. For those investments in limited partnerships for which the Company does not have a significant influence, such investments are accounted for using the cost method of accounting and the annual amortization is based on the proportion of tax credits received in the current year to the total estimated tax credits to be allocated to the Company
Comprehensive Income	Comprehensive 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, cash flow hedges, 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, 2014 or 2013.
	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 13 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 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, accounting for 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 ACILs, 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—Some items in the prior year financial statements were reclassified to conform to the current presentation.
Recent Accounting Pronouncements and Newly Issued But Not Yet Effective Accounting Pronouncements	Recently Issued Accounting Pronouncements
	FASB ASU No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The provisions of ASU No. 2013-11 require an entity to present an unrecognized tax benefit, or portion thereof, in the statement of financial position as a reduction to adeferred tax asset for a net operating loss carryforward or a tax credit carryforward, with certain exceptions related to availability. ASU No. 2013-11 is effective for interim and annual reporting periods beginning after December 15, 2013. The adoption of ASU No. 2013-11 did not have a material impact on the Company's consolidated financial statements.
	FASB ASU No. 2014-01, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. These amendments permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Disclosures for a change in accounting principle are required upon transition. ASU 2014-01 is effective for for interim and annual periods beginning after December 15, 2014 and is not expected to have a significant impact on the Company's financial statements.
	FASB ASU No. 2014-04, Receivables—Troubled Debt Restructuring by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure. The amendment intends to clarify the terms defining when an in substance foreclosure occurs, which determines when the receivable should be derecognized and the real estate property recognized. ASU No. 2014-04 will be effective for interim and annual periods beginning after December 31, 2014. ASU No. 2014-04 is not expected to have a material impact on the Company's consolidated financial statements.
	FASB ASU No. 2014-12, Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The amendments in ASU 2014-12 require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The performance target should not be reflected in estimating the grant date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. ASU 2014-12 is effective for interim and annual periods beginning after December 31, 2014 and is not expected to have a significant impact on the Company's financial statements.
	FASB ASU No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. The amendments in ASU 2014-15 defines management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and provide related disclosures. Currently, GAAP does not provide guidance to evaluate whether there is substantial doubt about the organization’s ability to continue as a going concern. Guidance is provided to an organization’s management, with principles and definitions to reduce diversity in the timing and content of disclosures commonly provided by organizations today in the financial statements footnotes. ASU 2014-15 is effective for interim and annual periods ending after December 15,
	2016 and is not expected to have an impact on the Company's 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 and result in a Level 2 classification.
	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 and result in a Level 2 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.
