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 Hope Bancorp and its wholly owned subsidiaries, principally Bank of Hope. 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 September 30, 2016 and the results of operations for the three and nine months ended September 30, 2016 . 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 (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially 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. The assets acquired and liabilities assumed from Wilshire were accounted for in accordance with ASC 805 “Business Combinations,” using the acquisition method of accounting and were recorded at their estimated fair values on the date of acquisition. These fair value estimates are considered provisional, as additional analysis may be performed on certain assets and liabilities in which fair values are primarily determined through the use of inputs that are not observable from market-based information. Management may further adjust the provisional fair values for a period of up to one year from the date of the acquisition. Any adjustment made to provisional amounts will be recorded in the reporting period in which the adjustment is recognized and will not be applied retrospectively as stated in ASU 2015-16 “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments”. The assets and liabilities that continue to be provisional include fixed asset, loans, intangible assets, OREO, deferred tax assets, accrued assets and liabilities, and the residual effects that the adjustments would have on goodwill. 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: In May 2016, the FASB issued ASU 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients.” ASU 2016-12 provides clarity and simplification to the transition guidance from the previously issued ASU 2014-09. The amendment provides narrow scope improvements to assessing the collectability criterion, the presentation of sales and other similar taxes, non-cash consideration, contract modifications, completed contracts, and technical corrections. ASU 2106-12 becomes effective for annual periods, and interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. ASU 2016-13 becomes effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” ASU 2016-15 provides guidance on classification and presentation of certain cash receipts and cash payments on an institution’s statement of cash flows. The amendment aims to reduce the diversity in practice with respects to certain types of cash flows. ASU 2016-15 becomes effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements.

Business Combinations [Abstract]
Business Combinations	Business Combinations The Company applies the acquisition method of accounting for business combinations, including the acquisition of Wilshire under ASC 805 “Business Combinations”. Under the acquisition method of accounting, 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 Wilshire Bancorp, Inc. On July 29, 2016, the Company completed the acquisition of Wilshire Bancorp, Inc. (“Wilshire”), the holding company of Wilshire Bank. The Company acquired Wilshire in order to expand its network of branch locations and to provide enhanced products and services to our customers. Wilshire’s primary subsidiary, Wilshire Bank, previously operated thirty-five branches located in California, New York, New Jersey, Texas, Georgia, and Alabama. Approximately $4.63 billion in assets were acquired through the transaction including $3.80 billion loans receivable and $3.81 billion in deposits. Subsequent to the acquisition, the Bank now operates 85 branches in nine difference states throughout the United States and also has loan production offices throughout the Unites States and a representative office in Seoul, Korea. Under the terms of the acquisition agreement, Wilshire shareholders received 0.7034 shares of Hope Bancorp common stock for each share of Wilshire common stock owned. As a result, 55.5 million shares of Hope Bancorp common stock were issued to Wilshire shareholders in addition to $3.1 thousand that was paid for fractional shares. In addition, the Company issued Hope stock options and restricted stock in exchange for Wilshire stock options and restricted stock outstanding at July 29, 2016 under substantially the same terms as were applicable immediately prior to the merger, subject to adjustment for the exchange ratio. Total consideration for the acquisition was $856.3 million . The consideration paid, the assets acquired, and the liabilities assumed are summarized in the following table: (In thousands) Consideration Paid: Hope common stock issued in exchange for Wilshire common stock $ 852,939 Cash paid for fractional shares 3 Hope stock options issued in exchange Wilshire stock options 3,370 Total consideration paid $ 856,312 Assets Acquired: Cash and cash equivalents $ 100,127 Investment securities available for sale 478,938 Loans receivable 3,800,807 FRB and FHLB stock 16,539 OREO 14,866 Premises and equipment 16,812 Bank owned life insurance 25,240 Servicing assets 16,203 Low income housing tax credit investments 47,111 Core deposit intangibles 18,138 Deferred tax assets, net 15,373 Other assets 77,482 Liabilities Assumed: Deposits (3,812,367 ) Borrowings (206,282 ) Subordinated debentures (56,942 ) Other liabilities (54,751 ) Total identifiable net assets $ 497,294 Excess of consideration paid over fair value of net assets acquired (goodwill) $ 359,018 The fair value estimates above are considered provisional and additional analysis may be performed. Fair values are primarily determined through the use of inputs that are not observable from market-based information. Management may further adjust the provisional fair values for a period of up to one year from the date of the acquisition. Any adjustment to provisional amounts will be applied prospectively. The assets and liabilities that continue to be provisional include fixed asset, loans, intangible assets, OREO, deferred tax assets, accrued assets and liabilities, and the residual effects that the adjustments would have on goodwill. Acquired Loans The fair value of loans were estimated on an individual basis based on the characteristics for each loan. A discounted cash flow analysis was used to project cash flows for each loan using assumptions for rate, remaining maturity, prepayment speeds, projected default probabilities, loss give defaults, and estimate of prevailing discount rates. The following table presents loans acquired from Wilshire with deteriorated credit quality as of the date of acquisition included as loans receivable in the table above: Fair Value At July 29, 2016 (In thousands) Contractually required principal and interest at acquisition $ 292,380 Contractual cash flows not expected to be collected (nonaccretable discount) (40,560 ) Expected cash flows at acquisition 251,820 Interest component of expected cash flows (accretable discount) (8,713 ) Fair value of acquired impaired loans $ 243,107 The outstanding principal balances and the related carrying amounts of the acquired loans included in the statement of financial condition at September 30, 2016 were $4.58 billion and $3.88 billion , respectively, for loan acquired from Wilshire. Pro Forma Information The operating results for Wilshire from the date of acquisition through September 30, 2016 are included in the Condensed Consolidated Statement of Income for 2016. The following unaudited combined pro forma information presents the operating results for the three and nine months ended September 30, 2016 and 2015, as if the Wilshire acquisition had occurred on January 1, 2015: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 (In thousands, except share data) Net interest income $ 114,530 $ 113,687 $ 343,829 $ 335,598 Provision for loan losses 6,500 1,300 8,500 3,800 Non interest income 18,119 22,754 55,751 71,108 Non interest expense 66,605 65,135 192,728 191,839 Income before tax provision 59,544 70,006 198,352 211,067 Tax provision 25,008 29,403 83,308 88,648 Net income $ 34,536 $ 40,603 $ 115,044 $ 122,419 Pro forma earnings per share: Basic $ 0.26 $ 0.30 $ 0.85 $ 0.91 Diluted $ 0.26 $ 0.30 $ 0.85 $ 0.91 The above pro forma results are presented for illustrative purposes only 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 acquisitions occurred at January 1, 2015, 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 or income synergies as a result of the acquisitions. In addition, merger-related costs, including those incurred by Wilshire, of $19.1 million for the three months ended September 30, 2016, and $22.8 million for the nine months ended September 30, 2016, were not included in the pro forma information. These pro forma results require significant estimates and judgments particularly as it relates to the valuation and accretion of income associated with acquired loans. Acquisition-Related Expenses The following table presents acquisition-related expenses associated with the acquisition Wilshire and other previous acquisitions which were reflected in the Condensed Consolidated Statements of Income in merger and integration expense. These expenses are comprised primarily of salaries and benefits, professional services, and other noninterest expense related to prior acquisitions. Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 (Dollars in thousands) Wilshire $ 11,198 $ — $ 13,890 $ — Other 24 24 72 102 Total merger related expenses $ 11,222 $ 24 $ 13,962 $ 102 Federally Assisted Acquisition of Mirae Bank The FDIC placed Mirae Bank (“Mirae”) under receivership upon Mirae’s closure by the California Department of Business Oversight (“DBO”) at the close of business on June 26, 2009. Wilshire purchased substantially all of Mirae’s assets and assumed all of Mirae’s deposits and certain other liabilities. Further, the Company entered into loss sharing agreements with the FDIC in connection with the Mirae acquisition. In June, 2014, the remaining loss-share agreement with the FDIC related to losses expired. As such, losses on loans acquired from Mirae Bank are no longer covered by the FDIC. However, recoveries will still be shared with the FDIC until June 2017.

Stock-Based Compensation

Stock-Based Compensation	9 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company has a stock-based incentive plan (the “2007 Plan”) to award equity as form of compensation. 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 2016 Stock Incentive Plan, adopted September 1, 2016. Stock options and restricted stock were assumed from the acquisition of Wilshire at substantially the same terms as those prior to the acquisition after applying the exchange ratio of 0.7034 . These stock awards were issued to former Wilshire employees and directors through the 2016 Plan. The 2016 Plan provides for the granting of incentive stock option, stock appreciation right, and restricted stock award to officers, employees, and consultants. The plan has 2,400,000 shares available for grant to participants. The option prices of all options granted under the 2016 Plan may not be less than 100% of the fair market value at the date of grant. All options not exercised generally expire ten years after the date of grant. Under the 2007 Plan and 2016 Plan, 1,369,416 shares were available for future grants as of September 30, 2016 . The total shares reserved for issuance will serve as the underlying value for all equity awards under the 2007 Plan and 2016 Plan. With the exception of the shares underlying stock options and restricted stock awards, the board of directors may choose to settle the awards by paying the equivalent cash value or by delivering the appropriate number of shares. The following is a summary of stock option activity under the 2007 Plan and 2016 Plan for the nine months ended September 30, 2016 : Number of Shares Weighted- Average Exercise Price Per Share Weighted- Average Remaining Contractual Life (Years) Aggregate Intrinsic Value Outstanding - January 1, 2016 457,851 $ 19.29 Granted 1,281,552 13.89 Exercised (76,669 ) 14.33 Expired (27,276 ) 19.96 Forfeited (4,395 ) 14.79 Outstanding - September 30, 2016 1,631,063 $ 15.28 6.85 $ 4,497,563 Options exercisable - September 30, 2016 886,930 $ 13.91 4.62 $ 4,391,041 The following is a summary of restricted stock and performance unit activity under the 2007 Plan and 2016 Plan for the nine months ended September 30, 2016 : Number of Shares Weighted- Average Grant Date Fair Value Outstanding - January 1, 2016 107,049 $ 13.72 Granted 424,908 16.56 Vested (106,681 ) 14.66 Forfeited (11,536 ) 13.23 Outstanding - September 30, 2016 413,740 $ 16.27 The total fair value of restricted performance units vested for the nine months ended September 30, 2016 and 2015 was $ 1.7 million and $746 thousand , respectively. The amount charged against income related to stock-based payment arrangements was $ 1.9 million and $ 261 thousand for the three months ended September 30, 2016 and 2015 , respectively. For the nine months ended September 30, 2016 and 2015, $2.0 million and $889 thousand , respectively, of stock-based payment arrangements were charged against income. The income tax benefit recognized was $ 761 thousand and $ 107 thousand for the three months ended September 30, 2016 and 2015 , respectively, and the amount recognized was $821 thousand and $359 thousand for the nine months ended September 30, 2016 and 2015, respectively. At September 30, 2016 , the unrecognized compensation expense related to non-vested stock option grants was $ 2.2 million which is expected to be recognized over a weighted average vesting period of 3.55 years. At September 30, 2016 , the unrecognized compensation expense related to non-vested restricted units and performance units was $6.3 million which is expected to be recognized over a weighted average vesting period of 2.97 years.

Earnings Per Share ("EPS")

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 equity awards, 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 September 30, 2016 , stock options and restricted shares awards for 609,186 shares of common stock were excluded in computing diluted earnings per common share because they were anti-dilutive. For the nine months ended September 30, 2016, stock options and restricted share awards of 559,790 shares were excluded in computing diluted earnings per share because they were anti-dilutive. Additionally, warrants issued pursuant to the Company’s participation in the U.S. Treasury’s TARP Capital Purchase Plan, to purchase 19,703 shares and 19,151 shares of common stock were anti-dilutive and excluded for the three and nine months ended September 30, 2016 and 2015 , respectively. The following tables show the computation of basic and diluted EPS for the three and nine months ended September 30, 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 corporate securities that were in a continuous unrealized loss position for twelve months or longer as of September 30, 2016 . The corporate securities at September 30, 2016 had a total amortized cost of $19.6 million and an unrealized loss of $ 768 thousand at September 30, 2016 . The last of the corporate securities are scheduled to mature in May 2047. These securities were rated investment grade and there were no credit quality concerns with the issuer. The collateralized mortgage obligations and mortgage-backed securities in a continuous loss position for twelve months or longer had an unrealized loss of $340 thousand and $0 thousand , respectively at September 30, 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 corporate 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 corporate securities and the U.S. Government agency and U.S. Government sponsored collateralized mortgage obligations and mortgage-backed securities that were in an unrealized loss position at September 30, 2016 . The Company considers the losses on the investments in unrealized loss positions at September 30, 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.

Loans Receivable and Allowance for Loan Losses	7. Loans Receivable and Allowance for Loan Losses The following is a summary of loans receivable by major category: September 30, 2016 December 31, 2015 (In thousands) Loan portfolio composition Real estate loans: Residential $ 60,280 $ 33,797 Commercial & industrial 7,887,734 4,912,655 Construction 210,857 123,030 Total real estate loans 8,158,871 5,069,482 Commercial business 1,829,785 980,153 Trade finance 182,128 99,163 Consumer and other 392,608 102,573 Total loans outstanding 10,563,392 6,251,371 Deferred loan fees (2,195 ) (3,030 ) Loans receivable 10,561,197 6,248,341 Allowance for loan losses (79,976 ) (76,408 ) Loans receivable, net of allowance for loan losses $ 10,481,221 $ 6,171,933 The loan portfolio is made up of four segments: real estate loans, commercial business, trade finance and consumer and other. These segments are further segregated between loans accounted for under the amortized cost method (“Legacy Loans”) and previously 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 Purchased Credit Impaired Loans (loans with credit deterioration on the acquisition date and accounted for under ASC 310-30, or “PCIs”) and Acquired Performing Loans (loans that were pass graded on the acquisition date and the fair value adjustment is amortized over the contractual life under ASC 310-20, or “non-PCIs”). The following table presents changes in the accretable discount on the PCI loans for the three and nine months ended September 30, 2016 and 2015 : Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 (In thousands) Balance at beginning of period $ 20,150 $ 21,389 $ 23,777 $ 24,051 Additions due to acquisitions during the period 8,713 — 8,713 — Accretion (2,630 ) (2,978 ) (8,133 ) (9,211 ) Changes in expected cash flows 40 7,042 1,916 10,613 Balance at end of period $ 26,273 $ 25,453 $ 26,273 $ 25,453 On the acquisition date, the amount by which the undiscounted expected cash flows exceed the estimated fair value of the PCI loans is the “accretable yield.” The accretable yield is then measured at each financial reporting date and represents the difference between the remaining undiscounted expected cash flows and the current carrying value of the loans. The accretable yield 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 PCI loans may change; and 3) estimates of the amount of the contractual principal and interest that will not be collected (nonaccretable difference) may change.

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 only 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, PCI loans that are contractually past due are still considered to be accruing and performing loans. The loans may be classified as nonaccrual if the timing and amount of future cash flows is not reasonably estimable. 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 borrower or by the collateral pledged, if any. Loans in this classification 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 PCI loans, 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 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.

Borrowings	Borrowings The Company maintains a line of credit with the FHLB of San Francisco for use as a secondary source of funds. The borrowing capacity with the FHLB is limited to the lower of 25% of the Bank’s total assets which was $2.08 billion at September 30, 2016 , and $2.36 billion at December 31, 2015 . 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, 2016 and December 31, 2015 , real estate secured loans with a carrying amount of approximately $3.46 billion and $3.13 billion , respectively, were pledged as collateral for borrowings from the FHLB. At September 30, 2016 and December 31, 2015 , other than FHLB stock, no securities were pledged as collateral for borrowings from the FHLB. At September 30, 2016 and December 31, 2015 , FHLB advances totaled $754.7 million and $530.6 million , respectively, and had a weighted average interest rate of 1.19% and 1.15% , respectively, and had various maturities through July 2021 . At September 30, 2016 and December 31, 2015 , $20.3 million and $20.6 million , respectively, of the advances were putable advances with various putable dates and strike prices. The stated rate of FHLB advances as of September 30, 2016 ranged between 0.36% and 2.02% . At September 30, 2016 , the Company had a remaining borrowing capacity of $1.32 billion . At September 30, 2016 , the contractual maturities for FHLB advances were as follows: Contractual Maturity/ (In thousands) Due within one year $ 180,299 $ 180,299 Due after one year through five years 574,440 574,440 $ 754,739 $ 754,739 Through the acquisition of Wilshire, the Company acquired three FHLB advances totaling $200.0 million with an average weighted rate of 1.82% . Two of these advances totaling $100.0 million was paid off on August 1, 2016. The remaining $100.0 million FHLB advance is a term advances maturing on September 23, 2019 with a fixed rate of 2.48% . The remaining acquired advance was acquired at a premium of $4.7 million with $4.4 million remaining at September 30, 2016. As a member of the FRB system, the Bank may also borrow from the FRB of San Francisco. The maximum amount that the Bank 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 are pledged. At September 30, 2016 , the outstanding principal balance of the qualifying loans was $751.7 million , and the collateral value of investment securities was $1.1 million . There were no borrowings outstanding against this line as of September 30, 2016 and December 31, 2015 .

Subordinated Borrowings [Abstract]
Subordinated Debentures	Subordinated Debentures At September 30, 2016 , the Company had nine wholly owned subsidiary grantor trusts that had issued $126 million of pooled trust preferred securities. Trust preferred securities accrue and pay distributions periodically at specified annual rates as provided in the indentures. The trusts used the net proceeds from the offering to purchase a like amount of subordinated debentures (the “Debentures”). 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.

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. The Company acquired four subordinated debentures from the acquisition of Wilshire at the fair value of $56.9 million , which was net of purchase accounting discount of $25.5 million . The remaining discount on these debentures at September 30, 2016 was $25.4 million . All the acquired debentures are callable on quarterly basis.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Company offers a loan hedging program to certain loan customers. Through this program, the Company originates a variable rate loan with the customer. The Company and the customer will then enter into a fixed interest rate swap. Lastly, an identical offsetting swap is entered into by the Company with a correspondent bank. These “back-to-back” swap arrangements are intended to offset each other and allow the Company to book a variable rate loan, while providing the customer with a contract for fixed interest payments. In these arrangements, the Company’s net cash flow is equal to the interest income received from the variable rate loan originated with the customer. These customer swaps are not designated as hedging instruments and are recorded at fair value in other assets and other liabilities. The changes in fair value are recognized in the income statement in other income and fees. At September 30, 2016 , the following interest rate swaps related to our loan hedging program were outstanding: As of September 30, 2016 (Dollars in thousands) Interest rate swaps on loans with loan customers Notional amount $ 198,776 Weighted average remaining term 7.4 years Received fixed rate (weighted average) 4.27 % Pay variable rate (weighted average) 2.95 % Estimated fair value $ 8,910 Back to back interest rate swaps with correspondent banks Notional amount $ 198,776 Weighted average remaining term 7.4 years Received variable rate (weighted average) 2.95 % Pay fixed rate (weighted average) 4.27 % Estimated fair value $ (8,910 ) Subsequent to the acquisition of Wilshire, the Company began to enter into various stand-alone mortgage-banking derivatives in order to hedge the risk associated with the fluctuation of interest rates. Changes in fair value are recorded as mortgage banking revenue. Residential mortgage loans funded with interest rate lock commitments and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. At September 30, 2016, we had approximately $34.2 million in interest rate lock commitments and $26.8 million in total forward sales commitments for the future delivery of residential mortgage loans. There were no interest rate lock commitments or forward sales commitments in quarters prior to the quarter ended September 30, 2016. The following table reflects the notional amount and fair value of mortgage banking derivatives for the dates indicated: As of September 30, 2016 (Dollars in Thousands) Notional Amount Fair Value Assets: Interest rate lock commitments $ 23,687 $ 322 Forward sale contracts related to mortgage banking: $ 8,123 $ 24 Liabilities: Interest rate lock commitments $ 3,165 $ (18 ) Forward sale contracts related to mortgage banking: $ 18,729 $ (64 )

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets	ntangible Assets Goodwill represents the excess of the purchase price over the sum of the estimated fair values of the tangible and identifiable intangible assets acquired less the estimated fair value of the liabilities assumed. Goodwill has an indefinite useful life and is evaluated for impairment annually or more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. At December 31, 2015, management assessed the qualitative factors related to goodwill for the year to determine whether it was more-likely-than-not that the fair value was less than its carrying amount. Based on the analysis of these factors, management determined that it was more-likely-than-not that the fair value of goodwill exceeded the carrying value and that the two-step impairment test was not needed. Goodwill is not amortized for book purposes and is not tax deductible. The carrying amount of the Company’s goodwill as of September 30, 2016 and December 31, 2015 was $464.4 million , and $105.4 million , respectively. There was no impairment of goodwill during the three and nine months ended September 30, 2016 and 2015 . Goodwill recorded in the third quarter of 2016 from the acquisition of Wilshire totaled $359.0 million . 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 $565 thousand and $267 thousand for the three months ended September 30, 2016 and 2015 , respectively. The amortization expense related to core deposit intangible assets totaled $990 thousand and $801 thousand for the nine months ended September 30, 2016 and 2015. The following table provides information regarding the core deposit intangibles at September 30, 2016 : As of September 30, 2016 Amortization period Gross Carrying Amount Accumulated Amortization (In thousands) Core deposit—Center Financial Corporation acquisition 7 years $ 4,100 $ (3,578 ) Core deposit—PIB acquisition 7 years 603 (445 ) Core deposit—Foster acquisition 10 years 2,763 (1,260 ) Core deposit—Wilshire Bank acquisition 10 years 18,138 (353 ) Total $ 25,604 $ (5,636 ) The acquisition of the Wilshire on July 29, 2016 resulted in goodwill totaling $359.0 million and core deposits intangibles of $18.1 million . The core deposits intangibles from the acquisition of Wilshire represents 0.87% of core deposits and is currently scheduled to amortize for a period of 10 year ending 2026. Servicing assets are recognized when SBA or residential mortgage loans are sold with servicing retained with the income statement effect recorded in net gains on sales of SBA and other 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. 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 and nine months ended September 30, 2016 and 2015 were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 (In thousands) Balance at beginning of period $ 12,193 $ 10,935 $ 12,000 $ 10,341 Additions through originations of servicing assets 385 1,381 2,472 3,570 Additions through acquisition of Wilshire 16,203 — 16,203 — Amortization (2,252 ) (811 ) (4,146 ) (2,406 ) Balance at end of period $ 26,529 $ 11,505 $ 26,529 $ 11,505 The Company utilizes the discounted cash flow method to calculate the initial excess servicing assets. The inputs used in determining the fair value of the servicing assets at September 30, 2016 and December 31, 2015 are presented below. September 30, 2016 December 31, 2015 Range Range Weighted-average discount rate 5.54% ~ 6.07% 5.32% ~ 5.92% Constant prepayment rate 7.20% ~ 9.00% 7.00% ~11.90%

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 $3.6 million and $1.8 million at September 30, 2016 and December 31, 2015 , respectively that relate to uncertainties associated with federal and state income tax matters. Other than the accrued interest of $166 thousand related to uncertain tax positions from an acquired entity, the Company recognizes interest and penalties on income tax matters in income tax expense. The Company recorded approximately $376 thousand and $154 thousand for accrued interest and penalties ( no portion was related to penalties) at September 30, 2016 and December 31, 2015 , respectively. 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 2012. 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 2012 and 2013 tax years. Wilshire Bancorp, Inc., an acquired entity, is currently under examination by the California Franchise Tax Board (FTB) for the 2011, 2012, and 2013 tax years and by the New York State Department of Taxation and Finance for the 2011, 2012, 2013, and 2014 tax years. While the outcome of the examinations is unknown, the Company expects no material adjustments. 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, 2016 .

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair value. The fair value inputs of the instruments are classified and disclosed in one of the following categories pursuant to ASC 820: Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. The quoted price shall not be adjusted for any blockage factor (i.e., size of the position relative to trading volume). Level 2 - Pricing inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Fair value is determined through the use of models or other valuation methodologies, including the use of pricing matrices. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 3 - Pricing inputs are unobservable for the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. The inputs into the determination of fair value require significant management judgment or estimation. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The Company uses the following methods and assumptions in estimating our fair value disclosures for financial instruments. Financial assets and liabilities recorded at fair value on a recurring and non-recurring basis are listed as follows: 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 a quarterly 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. Mortgage banking derivatives Mortgage banking derivative instruments consist of interest rate lock commitments and forward sale contracts that trade in liquid markets. The fair value is based on the prices available from third party investors. Due to the observable nature of the inputs used in deriving the fair value, the valuation of mortgage banking derivatives are classified as Level 2. 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 September 30, 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 debt securities $ 12,026 $ — $ 12,026 $ — GSE collateralized mortgage obligations 719,247 — 719,247 — GSE mortgage-backed securities 717,560 — 717,560 — Corporate securities 18,878 — 18,878 — Municipal bonds 77,529 — 76,300 1,229 Mutual funds 13,479 13,479 — — Interest rate swaps 8,910 — 8,910 — Liabilities: Interest rate swaps 8,910 — 8,910 — 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 — Corporate 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 and nine months ended September 30, 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.

Pursuant to the merger agreement, Wilshire shareholders received 0.7034 shares of the Company’s common stock for each share of Wilshire stock owned. Based on this exchange ratio, $55.5 million shares of the Company’s common stock were issued to Wilshire shareholders at $15.37 per share, the closing price of the Company’s stock on July 29, 2016. As a result, $852.9 million in common stock was issued as consideration in the transaction and $3.4 million in additional paid-in capital was recorded to account for the fair value of stock options assumed. Total stockholders’ equity at September 30, 2016 was $1.85 billion , compared to $938.1 million at December 31, 2015. In June 2012, the Company redeemed all of the Fixed Rate Cumulative Perpetual Preferred Stock issued under the U.S. Treasury Department’s TARP Capital Purchase Program. The Company assumed certain warrants (related to the TARP Capital Purchase Plan) to purchase shares of the Company’s common stock. On May 20, 2015, the U.S. Treasury Department completed an auction to sell certain of its warrant positions, and the Company submitted the winning bid to repurchase an outstanding warrant to purchase 350,767 shares of the Company’s common stock. The Company repurchased this warrant for $1.2 million . As of September 30, 2016 , the U.S. Treasury Department held one remaining warrant for the purchase of 19,703 shares of the Company’s common stock. The Company’s Board of Directors paid quarterly dividends of $0.11 per common share for the third quarter of 2016 compared to $0.11 per common share for the third quarter of 2015.

Regulatory Matters

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 material and adverse effect on the Company’s and the Bank’s business, financial condition and results of operation, 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. 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 is being 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. The capital conservation buffer for the Company was 0.625% in 2016, to be increased in 0.625% annually until 2019. As of September 30, 2016 , the ratios for the Company and the Bank are sufficient to meet the fully phased-in conservation buffer. As of September 30, 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, common equity Tier 1, and Tier I leverage ratios as set forth in the table below.

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 (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially 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: In May 2016, the FASB issued ASU 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients.” ASU 2016-12 provides clarity and simplification to the transition guidance from the previously issued ASU 2014-09. The amendment provides narrow scope improvements to assessing the collectability criterion, the presentation of sales and other similar taxes, non-cash consideration, contract modifications, completed contracts, and technical corrections. ASU 2106-12 becomes effective for annual periods, and interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. ASU 2016-13 becomes effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” ASU 2016-15 provides guidance on classification and presentation of certain cash receipts and cash payments on an institution’s statement of cash flows. The amendment aims to reduce the diversity in practice with respects to certain types of cash flows. ASU 2016-15 becomes effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017. The Company is currently in the process of evaluating the impact of the pending adoption of the new standard on its consolidated financial statements.
