	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, 2012 which was derived from audited financial statements included in the Company's 2012 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 recurring accruals, that in the opinion of management, are necessary to fairly present the Company's financial position at September 30, 2013 and the results of operations for the three and nine months then ended. 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, the valuation of servicing assets, and the determination of the fair values of acquired assets and liabilities including the fair value of loans acquired with credit deterioration.
	These unaudited condensed consolidated financial statements should be read along with the audited consolidated financial statements and accompanying notes included in the Company's 2012 Annual Report on Form 10-K.
	Recent Accounting Pronouncements:
	FASB ASU No. 2013-11, "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 a deferred 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 is not expected to have a material impact on the Company's consolidated financial statements.

Business Combinations	'
	Business Combinations
	The Company applies the acquisition method of accounting for business combinations under ASC 805 - Business Combinations. Under the acquisition method, the acquiring entity in a business combination recognizes 100 percent of the assets acquired and liabilities assumed at their acquisition date fair values. Management utilizes valuation techniques appropriate for the asset or liability being measured in determining these fair values. Any excess of the purchase price over amounts allocated to assets acquired, including identifiable intangible assets, and liabilities assumed is recorded as goodwill. Where amounts allocated to assets acquired and liabilities assumed is greater than the purchase price, a bargain purchase gain is recognized. Acquisition-related costs are expensed as incurred as merger and integration expense.
	Acquisition of Foster Bankshares, Inc.
	On August 13, 2013, the Company completed the acquisition of Foster Bankshares, Inc. ("Foster"), the holding company of Foster Bank. The Company acquired Foster in order to expand its market in Illinois and into Virginia. Foster's primary subsidiary, Foster Bank, operated eight branches in Illinois and one branch in Virginia.
	Under the terms of the acquisition agreement, Foster shareholders can elect to receive a cash price of $34.6703 per share or, for shareholders who qualified as accredited investors, 2.62771 shares of Company common stock for each share of Foster common stock. As of September 30, 2013, the Company issued 54,620 shares of Company common stock in exchange for 20,790 shares of Foster common stock, paid $1.7 million for 49,496 shares of Foster common stock and there were 61,714 shares of Foster common stock that had not been redeemed.

	The assets and liabilities of Foster were recorded on the consolidated balance sheet at estimated fair value on the acquisition date. The purchase price may change as additional information becomes available and when unredeemed Foster shares are redeemed. The fair values of the net deferred tax assets, loans, and OREO acquired and certain liabilities assumed from Foster were provisional and adjustments to the provisional amounts may occur during the measurement period as the Company obtains additional information about the facts and circumstances that existed as of the acquisition date.
	Acquisition of Pacific International Bancorp, Inc.
	On February 15, 2013, the Company completed the acquisition of Pacific International Bancorp, Inc. ("PIB"), a Seattle based company, pursuant to an Agreement and Plan of Merger, dated October 22, 2012. The Company acquired PIB in order to increase the Company's presence in terms of branch offices and deposit market share in the Seattle market. PIB's primary subsidiary, Pacific International Bank, a Washington state-chartered bank, operated four bank branches in the Seattle metropolitan area.
	In connection with the acquisition, the consideration paid, the assets acquired, and the liabilities assumed are summarized in the following table:
			(In thousands)
	Consideration paid:
		BBCN common stock issued	$	8,437
		Cash in lieu of fractional shares paid to PIB stockholders	1

	Excess of consideration paid over fair value of net assets acquired (goodwill)		$	338
	The $29.7 million and $338 thousand of goodwill recognized in the Foster and PIB acquisitions, respectively, represent the future economic benefit arising from the acquisitions including the creation of a platform that can support future operations and strengthening the Company's existing presence in the Chicago metropolitan and Pacific Northwest markets and expansion into the Virginia market. Goodwill is not amortized for book purposes and is not deductible for tax purposes.
	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 $296.1 million and $239.0 million, respectively for Foster and $117.8 million and $112.6 million, respectively for PIB, as of September 30, 2013.
Pro Forma Information
The operating results of Foster and PIB from the dates of acquisitions through September 30, 2013 are included in the Condensed Consolidated Statement of Income for 2013 and are not material to the total consolidated operating results for the three and nine month periods ended September 30, 2013.
The following unaudited combined pro forma information presents the operating results for the three and nine months ended September 30, 2013 and 2012, as if the Foster and PIB acquisitions had occurred on January 1, 2012:

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, 2012, 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 three and nine months ended September 30, 2013, the Company incurred $1.2 million and $1.5 million, respectively, in expenses related to the Foster acquisition. During the three and nine months ended September 30, 2013, the Company incurred $29 thousand and $1.1 million, respectively, in expenses related to the PIB acquisition.

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 our 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 1% 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 1% 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 Center Financial Corporation 2006 Stock Incentive Plan, adopted April 12, 2006, as amended and restated June 13, 2007 (the "2006 Plan"), which was assumed by the Company during the merger with Center Bank.
	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 1% of the fair market value at the date of grant. All options granted generally vest at the rate of 0.2% per year except that the options granted to the non-employee directors vest at the rate of 0% per year. All options not exercised generally expire ten years after the date of grant.
	Under the 2007 and 2006 Plans, 2,739,703 shares were available for future grants as of September 30, 2013.
	The total shares reserved for issuance will serve as the underlying value for all equity awards under the 2007 and 2006 Plans. 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.
	The following is a summary of stock option activity under the 2007 and 2006 Plans for the nine months ended September 30, 2013:

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 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 three months ended September 30, 2013 and 2012, stock options and restricted shares awards for approximately 126 thousand shares and 565 thousand shares of common stock, respectively, were excluded in computing diluted earnings per common share because they were antidilutive. For the nine months ended September 30, 2013 and 2012, stock options and restricted shares awards for approximately 172 thousand shares and 564 thousand shares of common stock, respectively, were excluded in computing diluted earnings per common share because they were antidilutive. Additionally, warrants to purchase 51 thousand shares and 28 thousand shares of common stock (related to the TARP Capital Purchase Plan) were antidilutive and excluded for the three and nine months ended September 30, 2013, respectively. Warrants to purchase 337 thousand shares common stock (related to the TARP Capital Purchase Plan) were antidilutive and excluded for the three and nine months ended September 30, 2012.
	The following table shows the computation of basic and diluted EPS for the three months ended September 30, 2013 and 2012.

* Investments in U.S. Government agency and U.S. Government sponsored enterprises
The Company evaluates securities for other-than-temporary-impairment ("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 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 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 and U.S. Government agency and U.S. Government sponsored enterprise collateralized mortgage obligations that were in a continuous unrealized loss position for twelve months or longer as of September 30, 2013. The trust preferred securities at September 30, 2013 had an amortized cost of $4.5 million and an unrealized loss of $807 thousand at September 30, 2013. The trust preferred securities are scheduled to mature in May 2047. These securities are rated investment grade and there are no credit quality concerns with the obligor. Certain of the Company's U.S. Government agency and U.S. Government sponsored enterprise investments were in an unrealized loss position at September 30, 2013. All of the Company's U.S. Government agency and U.S. Government sponsored enterprise investments have high credit ratings ("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 are deemed to be due to the current market volatility and are not reflective of management’s expectations of its 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 September 30, 2013.
The Company considers the losses on the investments in unrealized loss positions at September 30, 2013 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 management 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"). The 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 and nine months ended September 30, 2013 and 2012:
		Three Months Ended September 30,								Nine Months Ended September 30,
		2013				2012				2013				2012
		(In thousands)
	Balance at beginning of period	$	37,090			$	22,966			$	18,651			$	31,999
	Additions due to acquisitions during the period	14,928				—				19,873				—
	Accretion	(4,250		)		(3,415		)		(11,281		)		(10,866		)
	Changes in expected cash flows	5,689				516				26,214				(1,066		)
	Balance at end of period	$	53,457			$	20,067			$	53,457			$	20,067
	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 collectability 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.

(3) Nonaccrual loans exclude guaranteed portion of delinquent SBA loans that are in liquidation totaling $17.6 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.
We categorize 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. We analyze 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. We use 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.

The adequacy of the allowance for loan losses is determined by management based upon an evaluation and review of the credit quality of the loan portfolio, consideration of historical loan loss experience, relevant internal and external factors that affect the collection of a loan, and other pertinent factors.
The Migration Analysis 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. Our 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. For the 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. 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; and
•	The effect of external factors, such as competition and legal and regulatory requirements, on the level of estimated losses in our loan portfolio.
We also establish 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, we either obtain 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 our collateral property has declined since the most recent valuation date, we adjust the value of the property downward to reflect current market conditions. 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, we base 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. We evaluate 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 our 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 our estimate of future credit losses over the remaining life of the loans.

Under certain circumstances, we provide borrowers relief through loan modifications. These modifications are either temporary in nature (“temporary modifications”) or are more substantive. At September 30, 2013, total modified loans were $60.7 million, compared to $51.5 million at December 31, 2012. 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 Special Mention or Substandard. 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 on 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 September 30, 2013 were comprised of 15 commercial real estate loans totaling $22.6 million, 30 commercial business loans totaling $12.9 million, and 2 consumer loans totaling $544 thousand. TDRs on accrual status at December 31, 2012 were comprised of 12 commercial real estate loans totaling $23.6 million, 20 commercial business loans totaling $5.8 million and 2 consumer loans totaling $536 thousand.  The Company expects that the TDRs on accrual status as of September 30, 2013, which were all performing in accordance with their restructured terms, to 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.
We have allocated $7.7 million and $6.3 million of specific reserves to TDRs as of September 30, 2013 and December 31, 2012, respectively.  As of September 30, 2013 and December 31, 2012, we did not have any outstanding commitments to extend additional funds to these borrowers.

Related Party Loans
In the ordinary course of business, the Company entered into loan transactions with certain of its directors or associates of such directors (“Related Parties”). The loans to Related Parties are on substantially the same terms and conditions, including interest rates and collateral, as those prevailing at the same time for comparable transactions with unrelated parties. In management’s opinion, these transactions did not involve more than normal credit risk or present other unfavorable features. All loans to Related Parties were current as of September 30, 2013 and December 31, 2012, and the outstanding principal balance as of September 30, 2013 and December 31, 2012 was $7.7 million and $11.1 million, respectively.

	We maintain a secured credit facility with the FHLB against which the Bank may take advances. The borrowing capacity is limited to the lower of 30% of the Bank’s total assets or the Bank’s collateral capacity, which was $1.58 billion at September 30, 2013 and $1.35 billion at December 31, 2012. The terms of this credit facility require the Company to pledge eligible collateral with the FHLB equal to at least 100% of outstanding advances.
	At September 30, 2013 and December 31, 2012, real estate secured loans with a carrying amount of approximately $2.08 billion and $2.04 billion, respectively, were pledged as collateral for borrowings from the FHLB. At September 30, 2013 other than FHLB stock, securities with a carrying value of $13.9 million were pledged as collateral for borrowings from the FHLB, and at December 31, 2012, no securities were pledged as collateral for borrowings from the FHLB.
	At September 30, 2013 and December 31, 2012, FHLB advances were $421.4 million and $420.7 million, had a weighted average interest rate of 1.10% and 1.24%, respectively, and had various maturities through October 2018. At September 30, 2013 and December 31, 2012, $51.4 million and $66.7 million, respectively, of the advances were putable advances with various putable dates and strike prices. The cost of FHLB advances as of September 30, 2013 ranged between 0.47% and 3.81%. At September 30, 2013, the Company had a remaining borrowing capacity of $1.18 billion.
	At September 30, 2013, the contractual maturities for FHLB advances were as follows:
		Contractual		Maturity/
		Maturities		Put Date
		(In thousands)
	Due within one year	$	39,000	$	76,446
	Due after one year through five years	382,446		345,000

	In addition, as a member of the FRB system, we may also borrow from the FRB of San Francisco. The maximum amount that we may borrow from the FRB’s discount window is up to 95% of the outstanding principal balance of the qualifying loans and the fair value of the securities that we pledge. At September 30, 2013, the outstanding principal balance of the qualifying loans was $465.9 million, and no borrowings were outstanding against this line.

	At September 30, 2013, four wholly-owned subsidiary grantor trusts established by former Nara Bancorp had issued $28 million of pooled Trust Preferred Securities (“trust preferred securities”) and one wholly-owned subsidiary grantor trust established by former Center Financial Corporation had issued $18 million of trust preferred securities. Upon the acquisition of PIB, the Company assumed one grantor trust established by former PIB which issued $15.0 million of trust preferred securities, which the Company redeemed on June 17, 2013. Upon the acquisition of Foster Bankshares, the Company assumed one grantor trust established by former Foster Bank which issued $15 million of 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. 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.

	-1	The Center Capital Trust I trust preferred security was assumed in the merger with Center Financial Corporation. The remaining discount was $5.5 million at September 30, 2013 and the effective rate of the security, including the effect of the discount accretion, was 6.03% at September 30, 2013.
	-2	The Foster Capital Trust I trust preferred security was assumed in the merger with Foster Bankshares. The remaining discount was $119 thousand at September 30, 2013 and the effective rate of the security, including the effect of the discount accretion, was 3.75% at September 30, 2013.
	The Company’s investment in the common trust securities of the issuer trusts of $1.9 million and $1.6 million at September 30, 2013 and December 31, 2012, 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 September 30, 2013, $55.4 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 September 30, 2013, we will be able to continue to include its existing trust preferred securities in Tier 1 capital under the Dodd-Frank Act.

	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 $0.97 million and $748 thousand at September 30, 2013 and December 31, 2012, respectively, that relate primarily to uncertainties related to California enterprise zone loan interest deductions.
	We anticipate an increase of approximately $416 thousand in the unrecognized tax benefit related to the California enterprise zone loan interest deduction.
	The statute of limitations related to the consolidated Federal income tax return is closed for all tax years up to and including 2008. The expiration of the statute of limitations related to the various state income and franchise tax returns varies by state. The Company is currently under examination by IRS for the 2010 and 2011 tax years and by the California Franchise Tax Board (FTB) for the 2009 and 2010 tax years. While the outcome of the examinations is unknown, the Company expects no material adjustments. Within the last twelve months, examinations by the City of New York for tax years 2007, 2008, and 2009, and the FTB for tax years 2007 and 2008, were concluded with no material adjustments.
	We recognize interest and penalties related to income tax matters in income tax expense.  We had approximately $44 thousand and $52 thousand for accrued interest and penalties at September 30, 2013 and December 31, 2012, 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 September 30, 2013.

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.
	Derivatives
	The fair value of our derivative financial instruments, including interest rate swaps and caps, is based on derivative valuation models using market data inputs as of the valuation date that can generally be verified and do not typically involve significant management judgments (Level 2 inputs).
	OREO
	OREO is fair valued at the time the loan is foreclosed upon and the asset is transferred to OREO. The value is based primarily on third party appraisals, less costs to sell 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.

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, accrued interest receivable and payable, 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 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.

	Stockholders’ Equity and Regulatory Matters
	The Company and the Bank are subject to various regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and the Bank’s financial statements, such as restrictions on the growth, expansion or the payment of dividends or other capital distributions or management fees. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.
	Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum ratios (set forth in the table below) of total and Tier I capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier I capital (as defined) to average assets (as defined). Management believes that, as of September 30, 2013 and December 31, 2012, the Company and the Bank met all capital adequacy requirements to which they are subject.
	As of September 30, 2013 and December 31, 2012, 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.
	In June 2012, the Company redeemed $55 million of our Fixed Rate Cumulative Perpetual Preferred Stock, Series B, issued by Center Financial under the Treasury Department's TARP Capital Purchase Program. A ten-year warrant to purchase Center Financial common stock issued in connection with Center Financial's sale of preferred stock to the Treasury Department was converted into a warrant to purchase BBCN Bancorp common stock upon our merger with Center. Reflecting the merger exchange ratio of 0.7805, the warrant now entitles the holder of the warrant to purchase, in one or more exercises of the warrant, up to 337,480 shares of BBCN Bancorp common stock at a price of $12.22 per share. The Company has not reached an agreement with the Treasury Department regarding repurchase of this warrant.
	In December 2008, PIB granted a ten-year warrant to purchase up to 127,785 shares of its common stock (in relation to the TARP Capital Purchase Plan) which were assumed by the Company upon the acquisition of PIB. On the acquisition date of February 15, 2013, these warrants were canceled and converted into a warrant to purchase BBCN Bancorp common stock. The warrant entitles the holder to purchase, on one or more exercises of the warrant, up to 18,045 shares of BBCN Bancorp common stock at a price of $54.03 per share. The warrant expires on December 12, 2018. The Company has not reached an agreement with the Treasury Department regarding repurchase of this warrant.

Basis of Presentation Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2013
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 recurring accruals, that in the opinion of management, are necessary to fairly present the Company's financial position at September 30, 2013 and the results of operations for the three and nine months then ended.
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, the valuation of servicing assets, and the determination of the fair values of acquired assets and liabilities including the fair value of loans acquired with credit deterioration.
New accounting pronouncements	'
	FASB ASU No. 2013-11, "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 a deferred 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 is not expected to have a material impact on the Company's 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.
