Organization, Consolidation and Presentation of Financial Statements [Abstract]
BBCN Bancorp, Inc.	BBCN Bancorp, Inc. 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, Annandale, Dallas, Denver, Portland, Seattle, and Northern California. The Company 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. On December 7, 2015 the Company announced the signing of a definitive agreement and plan of merger (the “Merger Agreement”) with Wilshire Bancorp, Inc. (“Wilshire”) pursuant to which Wilshire will merge (the “merger”) with and into BBCN Bancorp with BBCN Bancorp as the surviving corporation. As part of the merger, Wilshire Bank, a wholly-owned subsidiary of Wilshire, will merge with and into the Bank. Under the terms of the Merger Agreement, Wilshire shareholders will receive a fixed exchange ratio of 0.7034 of a share of the Company’s common stock in exchange for each share of Wilshire common stock they own in a 100% stock-for-stock transaction. The Merger Agreement contains customary representations and warranties, and each party has agreed to customary covenants, including, among others, covenants relating to the conduct of its business during the interim period between execution of the Merger Agreement and the closing time. In addition, the consummation of the Merger Agreement is subject to customary conditions and the receipt of requisite regulatory approvals. We currently expect to close the merger in mid-2016 subject to satisfaction of the conditions set forth in the Merger Agreement.

Basis Of Presentation [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements included herein have been prepared without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”), except for the Condensed Consolidated Statement of Financial Condition as of December 31, 2015 which was derived from audited financial statements included in the Company’s 2015 Annual Report on Form 10-K. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such SEC rules and regulations. The condensed consolidated financial statements include the accounts of BBCN Bancorp and its wholly owned subsidiaries, principally BBCN Bank. All intercompany transactions and balances have been eliminated in consolidation. The Company has made all adjustments, consisting solely of normal accruals, that in the opinion of management, are necessary to fairly present the Company’s financial position at March 31, 2016 and the results of operations for the three months then ended. Certain reclassifications have been made to prior period amounts to conform to the current year presentation. The results of operations for the interim periods are not necessarily indicative of results to be anticipated for the full year. The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles 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, the determination of the carrying value for cash surrender value of life insurance, the determination of the 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, accounting for lease arrangements, accounting for incentive compensation, profit sharing and bonus payments, and the valuation of servicing assets. These unaudited condensed consolidated financial statements should be read along with the audited consolidated financial statements and accompanying notes included in the Company’s 2015 Annual Report on Form 10-K. Recent Accounting Pronouncements: FASB ASU No. 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting or Fees Paid in a Cloud Computing Arrangement. The amendments in ASU 2015-05 provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The amendments do not change the accounting for a customer’s accounting for service contracts. As a result of the amendments, all software licenses within the scope of Subtopic 350-40 will be accounted for consistently with other licenses of intangible assets. The amendments became effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The adoption of ASU 2015-05 did not have a material effect on the Company’s financial statements. FASB ASU No. 2015-10, Technical Corrections and Improvements. The amendments in ASU 2015-10 represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have significant effect on current accounting practice or create a significant administrative cost to most entities. The amendments that require transition guidance became effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2015. The adoption of ASU 2015-10 did not have a significant impact on the Company’s financial statements. FASB ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. The FASB issued guidance that requires an acquirer in a business combination to recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments also require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the estimated amounts, calculated as if the accounting had been completed at the acquisition date. The amendments became effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2015. The adoption of ASU 2015-16 did not have a significant impact on the Company’s financial statements. FASB ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The amendments eliminate the current requirement for organizations to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities as noncurrent. The amendments become effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2016. The adoption of ASU 2015-17 is not expected to have a significant impact on the Company’s consolidated financial statements. FASB ASU No. 2016-01, Financial Instruments─Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments require equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The amendments become effective for fiscal years beginning after December 15, 2017. The adoption of ASU 2016-01 is not expected to have a significant impact on the Company’s consolidated financial statements. FASB ASU No. 2016-02, Leases (Topic 842). The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. FASB ASU No. 2016-07, Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting. The amendments eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments become effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and early adoption is permitted. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. FASB ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). The amendments are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations by amending certain existing illustrative examples and adding additional illustrative examples to assist in the application of the guidance. The amendments become effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. FASB ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments require recognition of all excess tax benefits and tax deficiencies through income tax expense or benefit in the income statement. Other amendments in ASU 2016-09 include guidance on the classification of share based payment transactions in the statement of cash flows and an option to account for forfeitures of share-based awards as they occur rather than estimating the compensation cost based on the number of awards that are expected to vest. The amendments become effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements.

Stock-Based Compensation

Stock-Based Compensation	3 Months Ended
	Mar. 31, 2016
Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company has a stock-based incentive plan, the 2007 BBCN Bancorp Equity Incentive Plan (the “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 recognized 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 may not be 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 Plan and 2006 Plan, 2,589,428 shares were available for future grants as of March 31, 2016 . The total shares reserved for issuance will serve as the underlying value for all equity awards under the 2007 Plan and 2006 Plan.

Earnings Per Share [Abstract]
Earnings Per Share ("EPS")	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 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 three months ended March 31, 2016 , stock options and restricted shares awards for 443,956 shares of common stock were excluded in computing diluted earnings per common share because they were antidilutive. Additionally, warrants issued pursuant to the Company’s participation in the U.S. Treasury’s TARP Capital Purchase Plan, to purchase 19,420 shares and 18,882 shares of common stock were antidilutive and excluded for the three months ended March 31, 2016 and 2015 , respectively. The following tables show the computation of basic and diluted EPS for the three months ended March 31, 2016 and 2015 .

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 values of the securities have been less than the cost of 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, among other considerations, 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 collateralized mortgage obligations, mortgage-backed securities and trust preferred securities that were in a continuous unrealized loss position for twelve months or longer as of March 31, 2016 . The trust preferred securities at March 31, 2016 had an amortized cost of $4.5 million and an unrealized loss of $ 1.2 million at March 31, 2016 . The trust preferred securities are scheduled to mature in May 2047. These securities were rated investment grade and there were no credit quality concerns with the obligor. The collateralized mortgage obligations and mortgage-backed securities in a continuous loss position for twelve months or longer had an unrealized loss of $676 thousand and $547 thousand , respectively at March 31, 2016 . These securities were issued by U.S. Government agency and U.S. Government sponsored enterprises and have high credit ratings of “AA” grade or better. Interest on the trust preferred securities and the U.S. Government agency and U.S. Government sponsored enterprise investments have been paid as agreed, and management believes this will continue in the future and that the securities will be repaid in full as scheduled. The market value declines for these securities were primarily due to movements in interest rates and are not reflective of management’s expectations of the Company’s ability to fully recover these investments, which may be at maturity. For these reasons, no OTTI was recognized on the trust preferred securities and the U.S. Government agency and U.S. Government sponsored collateralized mortgage obligations and mortgage-backed securities that are in an unrealized loss position at March 31, 2016 . The Company considers the losses on the investments in unrealized loss positions at March 31, 2016 to be temporary based on: 1) the likelihood of recovery; 2) the information relative to the extent and duration of the decline in market value; and 3) the Company’s intention not to sell, and management’s determination that it is more likely than not that the Company will not be required to sell a security in an unrealized loss position before recovery of its amortized cost basis.

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”). Acquired Loans are further segregated between Acquired Credit Impaired Loans (loans with credit deterioration on the acquisition date and accounted for under ASC 310-30, or “ACILs”) and Acquired Performing Loans (loans that were pass graded on the acquisition date and the fair value adjustment is amortized over the contractual life under ASC 310-20, or “APLs”). The following table presents changes in the accretable discount on the ACILs for the three months ended March 31, 2016 and 2015 : Three Months Ended March 31, 2016 2015 (In thousands) Balance at beginning of period $ 23,777 $ 24,051 Accretion (3,029 ) (1,555 ) Changes in expected cash flows 1,349 149 Balance at end of period $ 22,097 $ 22,645 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) indices 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.

Generally, loans are placed on nonaccrual status 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, as well as when required by regulatory requirements. 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.

(2) Nonaccrual loans exclude guaranteed portion of delinquent SBA loans that are in liquidation totaling $18.7 million . Loans accounted for under ASC 310-30 are generally considered accruing and performing loans and the accretable discount is accreted to interest income over the estimated 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. The Company categorizes loans 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 definitions for risk ratings are as follows: • Pass: Loans that meet a preponderance or more of the Company’s underwriting criteria and evidence an acceptable level of risk. • Special Mention: Loans that 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 that 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 that 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.

Migration analysis is a formula methodology derived from the Bank’s actual historical net charge off experience for each loan class (type) pool and risk grade. The migration analysis (“Migration Analysis”) is centered on the Bank’s internal credit risk rating system. Management’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 migration analysis methodology described above. 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 on the most recent loss history. That loss experience is then applied to the stratified portfolio at each quarter end. For ACILs, a general loan loss allowance is provided to the extent that there has been credit deterioration since the date of acquisition. 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. 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; and • 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 that 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, management obtains 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, management either obtains updated appraisals every twelve months from a qualified independent appraiser or an internal evaluation of the collateral is performed by qualified personnel. If the third party market data indicates that the value of the collateral property has declined since the most recent valuation date, management adjusts the value of the property downward to reflect current market conditions. If the fair value of the collateral is less than the recorded amount of the loan, management recognizes 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 Company 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, management 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 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. For ACILs, the allowance for loan losses 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 an estimate of future credit losses over the remaining life of the loans.

Derivative Financial Instruments [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Derivative Financial Instruments The Company offers a loan hedging program to certain loan customers. Through this program, the Company originates a variable rate loan with the customer. The Company and the customer will then enter into a fixed interest rate swap. Lastly, an identical offsetting swap is entered into by the Company with a correspondent bank. These “back-to-back” swap arrangements are intended to offset each other and allow the Company to book a variable rate loan, while providing the customer with a contract for fixed interest payments. In these arrangements, the Company’s net cash flow is equal to the interest income received from the variable rate loan originated with the customer. These customer swaps are not designated as hedging instruments and are recorded at fair value in other assets and other liabilities. The changes in fair value are recognized in the income statement in other income and fees. At March 31, 2016 , the following interest rate swaps related to our loan hedging program were outstanding: As of March 31, 2016 Interest rate swaps on loans with loan customers Notional amount (in thousands) $ 120,583 Weighted average remaining term 7.5 years Received fixed rate (weighted average) 4.45 % Pay variable rate (weighted average) 2.81 % Estimated fair value (in thousands) $ 6,260 Back to back interest rate swaps with correspondent banks Notional amount (in thousands) $ 120,583 Weighted average remaining term 7.5 years Received variable rate (weighted average) 2.81 % Pay fixed rate (weighted average) 4.45 % Estimated fair value (in thousands) $ (6,260 )

Subordinated Borrowings [Abstract]
Subordinated Debentures	Subordinated Debentures At March 31, 2016 , the Company had five wholly owned subsidiary grantor trusts that had issued $46 million of pooled trust preferred securities. Trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in the indentures. The trusts used the net proceeds from the offering to purchase a like amount of subordinated debentures (the “Debentures”) of BBCN Bancorp. The Debentures are the sole assets of the trusts. The Company’s obligations under the subordinated debentures and related documents, taken together, constitute a full and unconditional guarantee by the Company of the obligations of the trusts. The trust preferred securities are mandatorily redeemable upon the maturity of the Debentures, or upon earlier redemption as provided in the indentures. The Company has the right to redeem the Debentures in whole (but not in part) on or after specific dates, at a redemption price specified in the indentures plus any accrued but unpaid interest to the redemption date. The Company also has a right to defer consecutive payments of interest on the debentures for up to five years. The following table is a summary of trust preferred securities and Debentures at March 31, 2016 : Issuance Trust Issuance Date Trust Preferred Security Amount Carrying Value of Subordinated Debentures Rate Type Current Rate Maturity Date (Dollars in thousands) Nara Capital Trust III 6/5/2003 $ 5,000 $ 5,155 Variable 3.78 % 6/15/2033 Nara Statutory Trust IV 12/22/2003 5,000 5,155 Variable 3.47 % 1/7/2034 Nara Statutory Trust V 12/17/2003 10,000 10,310 Variable 3.59 % 12/17/2033 Nara Statutory Trust VI 3/22/2007 8,000 8,248 Variable 2.28 % 6/15/2037 Center Capital Trust I 12/30/2003 18,000 13,503 Variable 3.47 % 1/7/2034 TOTAL ISSUANCE $ 46,000 $ 42,371 The Company’s investment in the common trust securities of the issuer trusts of $1.5 million and $1.5 million at March 31, 2016 and December 31, 2015 , 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.

Intangible Assets	ntangible Assets The carrying amount of the Company’s goodwill as of March 31, 2016 and December 31, 2015 was $105.4 million . There was no impairment of goodwill during the three months ended March 31, 2016 and 2015 . Core deposit intangible assets are amortized over their estimated lives, which range from seven to ten years. Amortization expense related to core deposit intangible assets totaled $212 thousand and $267 thousand for the three months ended March 31, 2016 and 2015 , respectively. The following table provides information regarding the core deposit intangibles at March 31, 2016 : As of March 31, 2016 Amortization period Gross Carrying Amount Accumulated Amortization (In thousands) Core deposit—Center Financial Corporation acquisition 7 years $ 4,100 $ (3,365 ) Core deposit—PIB acquisition 7 years 603 (401 ) Core deposit—Foster acquisition 10 years 2,763 (1,093 ) Total $ 7,466 $ (4,859 ) Servicing assets are recognized when SBA loans are sold with servicing retained with the income statement effect recorded in net 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 the carrying amount. Impairment is determined by stratifying rights into groupings based on loan type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. The changes in servicing assets for the three months ended March 31, 2016 were as follows: Three Months Ended March 31, 2016 2015 (In thousands) Balance at beginning of period $ 12,000 $ 10,341 Additions through originations of servicing assets 777 1,045 Amortization (921 ) (857 ) Balance at end of period $ 11,856 $ 10,529 The Company utilizes the discounted cash flow method to calculate the initial excess servicing assets.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company and its subsidiaries are subject to U.S. federal income tax, as well as state income taxes. The Company had total unrecognized tax benefits of $1.8 million and $1.8 million at March 31, 2016 and December 31, 2015 , respectively, that relate primarily to uncertainties in California enterprise zone loan interest deductions. Management believes it is reasonably possible that the unrecognized tax benefits may decrease by approximately $329 thousand in the next twelve months. The statute of limitations for the assessment of income taxes related to the consolidated Federal income tax returns is closed for all tax years up to and including 2011. The expiration of the statute of limitations for the assessment of income and franchise taxes related to the various state income and franchise tax returns varies by state. The Company is currently under examination by the California Franchise Tax Board (FTB) for the 2009, 2010, 2012, and 2013 tax years. While the outcome of the examinations is unknown, the Company expects no material adjustments. The Company recognizes interest and penalties related to income tax matters in income tax expense. The Company recorded approximately $169 thousand and $154 thousand for accrued interest and penalties at March 31, 2016 and December 31, 2015 , respectively. 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 March 31, 2016 .

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Accounting guidance establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect estimates of assumptions that market participants would use in pricing the asset or liability. Securities Available for Sale The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The fair values of the Company’s Level 3 securities available for sale were measured using an income approach valuation technique. The primary inputs and assumptions used in the fair value measurement were derived from the securities’ underlying collateral, which included discount rates, prepayment speeds, payment delays, and an assessment of the risk of default of the underlying collateral, among other factors. Significant increases or decreases in any of the inputs or assumptions would result in a significant increase or decrease in the fair value measurement. Impaired Loans The fair values of impaired loans are generally measured for impairment using the practical expedients permitted by FASB ASC 310-10-35 including impaired loans measured at an observable market price (if available), or at the fair value of the loan’s collateral (if the loan is collateral dependent). Fair value of the loan’s collateral, when the loan is dependent on collateral, is determined by appraisals or independent valuation, less costs to sell of 8.5%. For commercial and industrial and asset backed loans, independent valuations may be comprised of a 20-60% discount for accounts receivable and a 50-70% discount for inventory. These result in a Level 3 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 of 8.5% and result in a Level 3 classification of the inputs for determining fair value. OREO is reviewed and evaluated on at least an annual basis for additional impairment and adjusted to lower of cost or market accordingly, based on the same factors identified above. Loans held for sale Loans held for sale are carried at the lower of cost or fair value, as determined by outstanding commitments from investors, or based on recent comparable sales (Level 2 inputs), if available, and if not available, are based on discounted cash flows using current market rates applied to the estimated life and credit risk (Level 3 inputs) or may be assessed based upon the fair value of the collateral, which is obtained from recent real estate appraisals (Level 3 inputs). These appraisals may utilize a single valuation approach or a combination of approaches including the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in Level 3 classification of the inputs for determining fair value. Assets and liabilities measured at fair value on a recurring basis are summarized below: Fair Value Measurements at the End of the Reporting Period Using March 31, 2016 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (In thousands) Assets: Securities available for sale: GSE collateralized mortgage obligations $ 498,026 $ — $ 498,026 $ — GSE mortgage-backed securities 526,910 — 526,910 — Trust preferred securities 3,394 — 3,394 — Municipal bonds 46,113 — 44,904 1,209 Mutual funds 13,454 13,454 — — Interest rate swaps 6,260 — 6,260 — Liabilities: Interest rate swaps 6,260 — 6,260 — Fair Value Measurements at the End of the Reporting Period Using December 31, 2015 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (In thousands) Assets: Securities available for sale: GSE collateralized mortgage obligations $ 449,980 $ — $ 449,980 $ — GSE mortgage-backed securities 498,047 — 498,047 — Trust preferred securities 3,749 — 3,749 — Municipal bonds 45,511 — 44,345 1,166 Mutual funds 13,269 13,269 — — Interest rate swaps 2,680 — 2,680 — Liabilities: Interest rate swaps 2,680 — 2,680 — There were no transfers between Level 1, 2 and 3 during the three months ended March 31, 2016 and 2015.

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

Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters The Company and the Bank are subject to various regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material and adverse effect on the Company’s and the Bank’s financial statements, such as restrictions on growth or the payment of dividends or other capital distributions or management fees. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Prompt corrective action provisions are not applicable to bank holding companies. In July, 2013, the federal bank regulatory agencies adopted final regulations, which revised their risk-based and leverage capital requirements for banking organizations to meet requirements of Dodd-Frank and to implement Basel III international agreements reached by the Basel Committee. The final rules began for the Company and the Bank on January 1, 2015 and are subject to a phase-in period through January 1, 2019. The final rules that had an impact on the Company and the Bank include: • An increase in the minimum Tier 1 capital ratio from 4.00% to 6.00% of risk-weighted assets; • A new category and a required 4.50% of risk-weighted assets ratio is established for “common equity Tier 1” as a subset of Tier 1 capital limited to common equity; • A minimum non-risk-based leverage ratio is set at 4.00%, eliminating a 3.00% exception for higher rated banks; • Changes in the permitted composition of Tier 1 capital to exclude trust preferred securities, mortgage servicing rights and certain deferred tax assets and include unrealized gains and losses on available for sale debt and equity securities; • The risk-weights of certain assets for purposes of calculating the risk-based capital ratios are changed for high volatility commercial real estate acquisition, development and construction loans, certain past due non-residential mortgage loans and certain mortgage-backed and other securities exposures; and • A new additional capital conservation buffer of 2.5% of risk weighted assets over each of the required capital ratios will be phased in from 2016 to 2019 and must be met to avoid limitations on the ability of the B ank to pay dividends, repurchase shares or pay discretionary bonuses. Management believes that the capital ratios for the Company and the Bank under Basel III will continue to exceed the well capitalized minimum capital requirements. As of March 31, 2016 , the ratios for the Company and the Bank are sufficient to meet the fully phased-in conservation buffer. As of March 31, 2016 and December 31, 2015 , the most recent regulatory notification categorized the Bank as “well-capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well-capitalized”, the Bank must maintain minimum total risk-based, Tier I risk-based and Tier I leverage ratios as set forth in the table below. There are no conditions or events since the notification that management believes have changed the Bank’s category. The Company’s and the Bank’s actual capital amounts and ratios are presented in the table below: Actual Required Minimum Capital Adequacy With Capital Buffer Required Amount Ratio Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) As of March 31, 2016 Common equity tier 1 capital (to risk weighted assets): Company $ 848,429 11.96 % $ 319,220 4.50 % $ 363,556 5.125 % N/A N/A Bank $ 882,569 12.45 % $ 319,097 4.50 % $ 363,416 5.125 % $ 460,918 6.50 % Total capital (to risk-weighted assets): Company $ 967,615 13.64 % $ 567,502 8.00 % $ 611,838 8.625 % N/A N/A Bank $ 960,808 13.55 % $ 567,284 8.00 % $ 611,603 8.625 % $ 709,105 10.00 % Tier I capital (to risk-weighted assets): Company $ 889,375 12.54 % $ 425,627 6.00 % $ 469,963 6.625 % N/A N/A Bank $ 882,569 12.45 % $ 425,463 6.00 % $ 469,782 6.625 % $ 567,284 8.00 % Tier I capital (to average assets): Company $ 889,375 11.44 % $ 310,909 4.00 % N/A N/A N/A N/A Bank $ 882,569 11.36 % $ 310,874 4.00 % N/A N/A $ 388,593 5.00 % Actual Required Required Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) As of December 31, 2015 Common equity tier 1 capital (to risk weighted assets): Company $ 833,868 12.08 % $ 310,732 4.5 % N/A N/A Bank $ 866,652 12.56 % $ 310,627 4.5 % $ 448,684 6.5 % Total capital (to risk-weighted assets): Company $ 953,132 13.80 % $ 552,412 8.00 % N/A N/A Bank $ 945,013 13.69 % $ 552,226 8.00 % $ 690,283 10.00 % Tier I capital (to risk-weighted assets): Company $ 874,771 12.67 % $ 414,309 6.00 % N/A N/A Bank $ 866,652 12.56 % $ 414,170 6.00 % $ 552,226 8.00 % Tier I capital (to average assets): Company $ 874,771 11.53 % $ 303,528 4.00 % N/A N/A Bank $ 866,652 11.43 % $ 303,410 4.00 % $ 379,262 5.00 %

Basis Of Presentation [Abstract]
Consolidation	The condensed consolidated financial statements include the accounts of BBCN Bancorp and its wholly owned subsidiaries, principally BBCN Bank. All intercompany transactions and balances have been eliminated in consolidation. The Company has made all adjustments, consisting solely of normal accruals, that in the opinion of management, are necessary to fairly present the Company’s financial position at March 31, 2016 and the results of operations for the three months then ended. Certain reclassifications have been made to prior period amounts to conform to the current year presentation. The results of operations for the interim periods are not necessarily indicative of results to be anticipated for the full year.
Use of estimates	The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles 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, the determination of the carrying value for cash surrender value of life insurance, the determination of the 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, accounting for lease arrangements, accounting for incentive compensation, profit sharing and bonus payments, and the valuation of servicing assets.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: FASB ASU No. 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting or Fees Paid in a Cloud Computing Arrangement. The amendments in ASU 2015-05 provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The amendments do not change the accounting for a customer’s accounting for service contracts. As a result of the amendments, all software licenses within the scope of Subtopic 350-40 will be accounted for consistently with other licenses of intangible assets. The amendments became effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The adoption of ASU 2015-05 did not have a material effect on the Company’s financial statements. FASB ASU No. 2015-10, Technical Corrections and Improvements. The amendments in ASU 2015-10 represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have significant effect on current accounting practice or create a significant administrative cost to most entities. The amendments that require transition guidance became effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2015. The adoption of ASU 2015-10 did not have a significant impact on the Company’s financial statements. FASB ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. The FASB issued guidance that requires an acquirer in a business combination to recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments also require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the estimated amounts, calculated as if the accounting had been completed at the acquisition date. The amendments became effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2015. The adoption of ASU 2015-16 did not have a significant impact on the Company’s financial statements. FASB ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The amendments eliminate the current requirement for organizations to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities as noncurrent. The amendments become effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2016. The adoption of ASU 2015-17 is not expected to have a significant impact on the Company’s consolidated financial statements. FASB ASU No. 2016-01, Financial Instruments─Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments require equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The amendments become effective for fiscal years beginning after December 15, 2017. The adoption of ASU 2016-01 is not expected to have a significant impact on the Company’s consolidated financial statements. FASB ASU No. 2016-02, Leases (Topic 842). The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. FASB ASU No. 2016-07, Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting. The amendments eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments become effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and early adoption is permitted. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. FASB ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). The amendments are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations by amending certain existing illustrative examples and adding additional illustrative examples to assist in the application of the guidance. The amendments become effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. FASB ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments require recognition of all excess tax benefits and tax deficiencies through income tax expense or benefit in the income statement. Other amendments in ASU 2016-09 include guidance on the classification of share based payment transactions in the statement of cash flows and an option to account for forfeitures of share-based awards as they occur rather than estimating the compensation cost based on the number of awards that are expected to vest. The amendments become effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements.
Income taxes	Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are 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.
