Accounting Policies [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Hanmi Financial Corporation (“Hanmi Financial,” the “Company,” “we,” “us” or “our”) is a bank holding company whose subsidiary is Hanmi Bank (the “Bank”). Our primary operations are related to traditional banking activities, including the acceptance of deposits and the lending and investing of money through operation of the Bank. Effective July 19, 2016, the Bank voluntarily withdrew from the Federal Reserve System ("Federal Reserve"). As a result, the Bank became a state non-member bank and will be regulated by the California Department of Business Oversight and the FDIC. During the third quarter in 2016, the Federal Reserve canceled the Bank's holdings of Federal Reserve stock for $14.4 million in cash. In management’s opinion, the accompanying unaudited consolidated financial statements of Hanmi Financial and its subsidiaries reflect all adjustments of a normal and recurring nature that are necessary for a fair presentation of the results for the interim period ended September 30, 2016 , but are not necessarily indicative of the results that will be reported for the entire year or any other interim period. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. The aforementioned unaudited consolidated financial statements are in conformity with GAAP. Such interim consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission. The interim information should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 (the “2015 Annual Report on Form 10-K”). The preparation of interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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 subject to change include, among other items, the determination of allowance for loan losses and various other assets and liabilities measured at fair value. Certain prior period amounts have been reclassified to conform to current period presentation. Descriptions of our significant accounting policies are included in Note 1 - Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements in our 2015 Annual Report on Form 10-K.

The issuers of these securities have not established any cause for default on these securities and the various rating agencies have reaffirmed these securities’ long-term investment grade status as of September 30, 2016 and December 31, 2015 . These securities have fluctuated in value since their purchase dates as market interest rates have fluctuated. The Company does not intend to sell these securities and it is more likely than not that we will not be required to sell the securities before the recovery of their amortized cost basis. In addition, the unrealized losses on municipal and corporate bonds are not considered other-than-temporarily impaired, as the bonds are rated investment grade and there are no credit quality concerns with the issuers. Interest payments have been made as scheduled, and management believes this will continue in the future and that the bonds will be repaid in full as scheduled. Therefore, in management’s opinion, all securities that have been in a continuous unrealized loss position for the past 12 months or longer as of September 30, 2016 and December 31, 2015 were not other-than-temporarily impaired, and therefore, no impairment charges as of September 30, 2016 and December 31, 2015 were warranted. Realized gains and losses on sales of securities and proceeds from sales of securities were as follows for the periods indicated: Three Months Ended Nine Months Ended 2016 2015 2016 2015 (in thousands) Gross realized gains on sales of securities $ 396 $ 2,048 $ 396 $ 6,310 Gross realized losses on sales of securities (350 ) — (350 ) (166 ) Net realized gains on sales of securities $ 46 $ 2,048 $ 46 $ 6,144 Proceeds from sales of securities $ 78,282 $ 44,782 $ 78,282 $ 352,224 For the three months ended September 30, 2016 , there was a $46,000 net gain in earnings resulting from the sale of securities that had previously been recorded as net unrealized gains of $321,000 in comprehensive income. For the three months ended September 30, 2015 , there was a $2.0 million net gain in earnings resulting from the sale of securities that had previously been recorded as net unrealized gains of $1.2 million in comprehensive income. For the nine months ended September 30, 2016 , there was a $46,000 net gain in earnings resulting from the sale of securities that had previously been recorded as net unrealized losses of $314,000 in comprehensive income. For the nine months ended September 30, 2015 , there was a $6.1 million net gain in earnings resulting from the sale of securities that had previously been recorded as net unrealized gains of $2.0 million in comprehensive income. Securities available for sale with market values of $ 108.5 million and $ 72.0 million as of September 30, 2016 and December 31, 2015 , respectively, were pledged to secure public deposits and for other purposes as required or permitted by law.

However, the allowance is an estimate that is inherently uncertain and depends on the outcome of future events. Management’s estimates are based on previous loss experience; volume, growth and composition of the loan portfolio; the value of collateral; and current economic conditions. Our lending is concentrated generally in real estate, commercial, SBA and trade finance lending to small and middle market businesses primarily in California, Texas and Illinois.

$ 25,145 Loan Quality Indicators As part of the on-going monitoring of the credit quality of our loan portfolio, we utilize an internal loan grading system to identify credit risk and assign an appropriate grade, from 0 to 8 , for each loan in our loan portfolio. Third party loan reviews are performed throughout the year. Additional adjustments are made when determined to be necessary. The loan grade definitions are as follows: Pass and Pass-Watch: Pass and pass-watch loans, grades 0-4, are in compliance in all respects with the Bank’s credit policy and regulatory requirements, and do not exhibit any potential or defined weaknesses as defined under Special Mention, Substandard or Doubtful. This category is the strongest level of the Bank’s loan grading system. It incorporates all performing loans with no credit weaknesses. It includes cash and stock/security secured loans or other investment grade loans. Special Mention: A special mention credit, grade 5, has potential weaknesses that deserve management’s close attention. If not corrected, these potential weaknesses may result in deterioration of the repayment prospects of the debt and result in a Substandard classification. Loans that have significant actual, not potential, weaknesses are considered more severely classified. Substandard: A substandard credit, grade 6, has a well-defined weakness that jeopardizes the liquidation of the debt. A credit graded Substandard is not protected by the sound worth and paying capacity of the borrower, or of the value and type of collateral pledged. With a Substandard loan, there is a distinct possibility that the Bank will sustain some loss if the weaknesses or deficiencies are not corrected. Doubtful: A doubtful credit, grade 7, is one that has critical weaknesses that would make the collection or liquidation of the full amount due improbable. However, there may be pending events which may work to strengthen the credit, and therefore the amount or timing of a possible loss cannot be determined at the current time. Loss: A loan classified as loss, grade 8, is considered uncollectible and of such little value that its continuance as an active bank asset is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this asset even though partial recovery may be possible in the future. Loans classified as loss are charged off in a timely manner. Under regulatory guidance, loans graded special mention or worse are considered criticized loans and loans graded substandard or worse are considered classified loans.

Impaired Loans Loans are considered impaired when the Bank will be unable to collect all interest and principal payments per the contractual terms of the loan agreement, unless the loan is well-collateralized and in the process of collection; or they are classified as Troubled Debt Restructurings (“TDRs”) because, due to the financial difficulties of the borrowers, we have granted concessions to the borrowers we would not otherwise consider; or when current information or events make it unlikely to collect in full according to the contractual terms of the loan agreements; or there is a deterioration in the borrower’s financial condition that raises uncertainty as to timely collection of either principal or interest; or full payment of both interest and principal is in doubt according to the original contractual terms. We evaluate loan impairment in accordance with applicable GAAP. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as a practical expedient, at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent, less estimated costs to sell. If the measure of the impaired loan is less than the recorded investment in the loan, the deficiency is either charged off against the allowance for loan losses or we establish a specific allocation in the allowance for loan losses. Additionally, loans that are considered impaired are specifically excluded from the quarterly migration analysis when determining the amount of the allowance for loan losses required for the period. The allowance for collateral-dependent loans is determined by calculating the difference between the outstanding loan balance and the value of the collateral as determined by recent appraisals. The allowance for collateral-dependent loans varies from loan to loan based on the collateral coverage of the loan at the time of designation as nonperforming. We continue to monitor the collateral coverage, using recent appraisals, on these loans on a quarterly basis and adjust the allowance accordingly.

Nonaccrual Loans and Nonperforming Assets Loans are placed on nonaccrual status when, in the opinion of management, the full timely collection of principal or interest is in doubt. Generally, the accrual of interest is discontinued when principal or interest payments become more than 90 days past due, unless management believes the loan is adequately collateralized and in the process of collection. However, in certain instances, we may place a particular loan on nonaccrual status earlier, depending upon the individual circumstances surrounding the loan’s delinquency. When a loan is placed on nonaccrual status, previously accrued but unpaid interest is reversed against current income. Subsequent collections of cash are applied as principal reductions when received, except when the ultimate collectability of principal is probable, in which case interest payments are credited to income. Nonaccrual loans may be restored to accrual status when principal and interest payments become current and full repayment is expected.

A debt restructuring is considered a TDR if we grant a concession, that we would not have otherwise considered to the borrower, for economic or legal reasons related to the borrower’s financial difficulties. Loans are considered to be TDRs if they were restructured through payment structure modifications such as reducing the amount of principal and interest due monthly and/or allowing for interest only monthly payments for three months or more. All TDRs are impaired and are individually evaluated for specific impairment using one of these three criteria: (1) the present value of expected 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. At September 30, 2016 and December 31, 2015 , $595,000 and $1.0 million , respectively, of allowance relating to these loans were included in the allowance for loan losses.

(4) Includes a modification of $250,000 through a payment deferral for the nine months ended September 30, 2015 . For the restructured loans on accrual status, we determined that, based on the financial capabilities of the borrowers at the time of the loan restructuring and the borrowers’ past performance in the payment of debt service under the previous loan terms, performance and collection under the revised terms are probable.

Outstanding balance of PCI loans, the undiscounted sum of all amounts including amounts deemed principal, interest, fees and penalties, were $ 19.6 million and $30.9 million , respectively as of September 30, 2016 and December 31, 2015. For PCI loans, at the time of acquisition we (i) calculated the contractual amount and timing of undiscounted principal and interest payments (the “undiscounted contractual cash flows”) and (ii) estimated the amount and timing of undiscounted expected principal and interest payments (the “undiscounted expected cash flows”). The difference between the undiscounted contractual cash flows and the undiscounted expected cash flows is the nonaccretable difference. The nonaccretable difference represents an estimate of the loss exposure of principal and interest related to the PCI loan portfolios; such amount is subject to change over time based on the performance of such loans. The carrying value of PCI loans is reduced by payments received, both principal and interest, and increased by the portion of the accretable yield recognized as interest income. The excess of expected cash flows at acquisition over the initial fair value of acquired impaired loans is referred to as the “accretable yield” and is recorded as interest income over the estimated life of the loans using the effective yield. If estimated cash flows are indeterminable, the recognition of interest income will cease. At acquisition, the Company may aggregate PCI loans into pools having common credit risk characteristics such as product type, geographic location and risk rating. Increases in expected cash flows over those previously estimated increase the accretable yield and are recognized as interest income prospectively. Decreases in the amount and changes in the timing of expected cash flows compared to those previously estimated decrease the accretable yield and usually result in a provision for loan losses and the establishment of an allowance for loan losses. As the accretable yield increases or decreases from changes in cash flow expectations, the offset is a decrease or increase to the nonaccretable difference. The accretable yield is measured at each financial reporting date based on information then currently available and represents the difference between the remaining undiscounted expected cash flows and the current carrying value of the loans. The Company removes loans from loan pools when the Company receives payment in settlement with the borrower, sells the loan, or foreclose upon the collatera

Subordinated Debentures The Company assumed Junior Subordinated Deferrable Interest Debentures (“Subordinated Debentures”) as a result of the acquisition of CBI with an unpaid principal balance of $26.8 million and an estimated fair value of $18.5 million . The $8.3 million discount is being amortized to interest expense through the debentures' maturity date of March 15, 2036. CBI formed a trust in 2005 and issued $26.0 million of Trust Preferred Securities (“TPS”) at 6.26 percent fixed rate for the first five years and a variable rate at the 3 month LIBOR plus 140 basis points thereafter and invested the proceeds in the Subordinated Debentures. The Company may redeem the Subordinated Debentures at an earlier date if certain conditions are met. The TPS will be subject to mandatory redemption if the Subordinated Debentures are repaid by the Company. Interest is payable quarterly , and the Company has the option to defer interest payments on the Subordinated Debentures from time to time for a period not to exceed five consecutive years. The amortization of discount was $ 67,000 and $46,000 for the three months ended September 30, 2016 , and 2015 , respectively, and $185,000 and $125,000 for the nine months ended September 30, 2016 , and 2015 , respectively.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Earnings per share (“EPS”) is calculated on both a basic and a diluted basis. Basic EPS excludes dilution and is computed by dividing 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 securities or other contracts to issue common stock were exercised or converted into common stock or resulted from the issuance of common stock that then shared in earnings, excluding common shares in treasury. For diluted EPS, weighted-average number of common shares included the impact of restricted stock under the treasury method. The Company amended all restricted stock agreements with time-based vesting criterion as of September 1, 2015 to allow for the payment of non-forfeitable dividends on unvested restricted stock, accordingly, we adopted the two-class method for EPS calculation pursuant to Accounting Standards Codification ("ASC") 260-10, Earnings Per Share . Unvested restricted stock containing rights to non-forfeitable dividends are considered participating securities prior to vesting and have been included in the earnings allocation in computing basic and diluted EPS under the two-class method. Basic EPS is computed by dividing net income, net of income allocated to participating securities, by the weighted-average number of common shares. For diluted EPS, weighted-average number of common shares include the diluted effect of stock options. The following table is a reconciliation of the components used to derive basic and diluted EPS for the periods indicated: Three Months Ended Nine Months Ended 2016 2015 2016 2015 (in thousands, except for share and per share data) Basic EPS: Net income $ 13,121 $ 13,959 $ 42,073 $ 38,997 Less: income allocated to unvested restricted shares 81 78 258 78 Income allocated to common shares $ 13,040 $ 13,881 $ 41,815 $ 38,919 Weighted-average shares for basic EPS 31,912,470 31,799,573 31,880,466 31,774,047 Basic EPS $ 0.41 $ 0.44 $ 1.31 $ 1.22 Effect of dilutive securities - options and unvested restricted stock 175,763 110,235 150,829 80,977 Diluted EPS: Income allocated to common shares $ 13,040 $ 13,881 $ 41,815 $ 38,919 Weighted-average shares for diluted EPS 32,088,233 31,909,808 32,031,295 31,855,024 Diluted EPS $ 0.41 $ 0.44 $ 1.31 $ 1.22 For the three months ended September 30, 2016 and 2015 , stock options of 12,034 and 29,000 , respectively, were not included in the computation of diluted EPS because their effect was anti-dilutive. For the nine months ended September 30, 2016 and 2015 , stock options of 74,389 and 57,000 , respectively, were not included in the computation of diluted EPS because their effect was anti-dilutive.

Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters Risk-Based Capital In July 2013, the Board of Governors of the Federal Reserve, the Office of the Comptroller of the Currency and the FDIC approved the Basel III regulatory capital framework and related changes under the Dodd-Frank Wall Street Reform and Consumer Protection Act. The rules revise minimum capital requirements and adjust prompt corrective action thresholds. The rules also revise the regulatory capital elements, add a new common equity Tier I capital ratio, and increase the minimum Tier I capital ratio requirement. The revisions permit banking organizations to retain, through a one-time election, the existing treatment for accumulated other comprehensive income. Basel III rules, including certain transitional provisions, became effective January 1, 2015, and its requirements are included in the capital ratios presented in the table shown below. In addition, a new capital conservation buffer of 2.5% began to be phased in effective January 1, 2016 through January 1, 2019, and must be met to avoid limitations on the ability of the Bank to pay dividends, repurchase shares or pay discretionary bonuses. In January 2016, the new capital conservation buffer requirement was 0.625% of risk-weighted assets and will increase each year until fully implemented in January 2019. The capital ratios of Hanmi Financial and the Bank as of September 30, 2016 and December 31, 2015 were as follows: Actual Minimum Regulatory Requirement Minimum to Be Categorized as “Well Capitalized” Amount Ratio Amount Ratio Amount Ratio (dollars in thousands) September 30, 2016 Total capital (to risk-weighted assets): Hanmi Financial $ 548,644 14.99 % $ 292,788 8.00 % N/A N/A Hanmi Bank $ 533,874 14.61 % $ 292,391 8.00 % $ 365,489 10.00 % Tier 1 capital (to risk-weighted assets): Hanmi Financial $ 508,181 13.89 % $ 219,591 6.00 % N/A N/A Hanmi Bank $ 493,411 13.50 % $ 219,293 6.00 % $ 292,391 8.00 % Common equity Tier 1 capital (to risk-weighted assets): Hanmi Financial $ 502,648 13.73 % $ 164,693 4.50 % N/A N/A Hanmi Bank $ 493,411 13.50 % $ 164,470 4.50 % $ 237,568 6.50 % Tier 1 capital (to average assets): Hanmi Financial $ 508,181 11.68 % $ 173,983 4.00 % N/A N/A Hanmi Bank $ 493,411 11.36 % $ 173,751 4.00 % $ 217,188 5.00 % December 31, 2015 Total capital (to risk-weighted assets): Hanmi Financial $ 499,076 14.91 % $ 267,760 8.00 % N/A N/A Hanmi Bank $ 496,710 14.86 % $ 267,377 8.00 % $ 334,222 10.00 % Tier 1 capital (to risk-weighted assets): Hanmi Financial $ 456,941 13.65 % $ 200,820 6.00 % N/A N/A Hanmi Bank $ 454,634 13.60 % $ 200,533 6.00 % $ 267,377 8.00 % Common equity Tier 1 capital (to risk-weighted assets): Hanmi Financial $ 456,941 13.65 % $ 150,615 4.50 % N/A N/A Hanmi Bank $ 454,634 13.60 % $ 150,400 4.50 % $ 217,244 6.50 % Tier 1 capital (to average assets): Hanmi Financial $ 456,941 11.31 % $ 161,620 4.00 % N/A N/A Hanmi Bank $ 454,634 11.27 % $ 161,399 4.00 % $ 201,749 5.00 %

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair Value Measurements ASC 820, Fair Value Measurements and Disclosures , defines fair value, establishes a framework for measuring fair value including a three-level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an 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. The three-level fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value are defined as follows: • 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, and other inputs that are observable or can be corroborated by observable market data. • Level 3 - Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Fair value is used on a recurring basis for certain assets and liabilities in which fair value is the primary basis of accounting. Additionally, fair value is used on a non-recurring basis to evaluate assets or liabilities for impairment or for disclosure purposes. We record securities available for sale at fair value on a recurring basis. Certain other assets, such as loans held for sale, impaired loans, OREO, and core deposit intangible, are recorded at fair value on a non-recurring basis. Non-recurring fair value measurements typically involve assets that are periodically evaluated for impairment and for which any impairment is recorded in the period in which the re-measurement is performed. The following methods and assumptions were used to estimate the fair value of each class of financial instrument below: Securities available for sale - The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges. If quoted prices are not available, fair values are measured using matrix pricing, which is a mathematical technique used widely 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, or other model-based valuation techniques requiring observable inputs other than quoted prices such as yield curve, prepayment speeds, and default rates. Level 1 securities include U.S. treasury securities and mutual funds that are traded on an active exchange or by dealers or brokers in active over-the-counter markets. The fair value of these securities is determined by quoted prices on an active exchange or over-the-counter market. Level 2 securities primarily include mortgage-backed securities, collateralized mortgage obligations, U.S. government agency securities, SBA loan pool securities, municipal bonds and corporate bonds in markets that are active. In determining the fair value of the securities categorized as Level 2, we obtain reports from nationally recognized broker-dealers detailing the fair value of each investment security held as of each reporting date. The broker-dealers use prices obtained from nationally recognized pricing services to value our fixed income securities. The fair value of the municipal securities is determined based on pricing data provided by nationally recognized pricing services. We review the prices obtained for reasonableness based on our understanding of the marketplace, and also consider any credit issues related to the bonds. As we have not made any adjustments to the market quotes provided to us and as they are based on observable market data, they have been categorized as Level 2 within the fair value hierarchy. Level 3 securities are instruments that are not traded in the market. As such, no observable market data for the instrument is available, which necessitates the use of significant unobservable inputs. Loans held for sale - Loans held for sale are all SBA loans and carried at the lower of cost or fair value. As of September 30, 2016 and December 31, 2015 , we had $6.4 million and $2.9 million SBA loans held for sale, respectively. Management obtains quotes, bids or pricing indication sheets on all or part of these loans directly from the purchasing financial institutions. Premiums received or to be received on the quotes, bids or pricing indication sheets are indicative of the fact that cost is lower than fair value. At September 30, 2016 , the entire balance of SBA loans held for sale was recorded at its cost. We record SBA loans held for sale on a nonrecurring basis with Level 2 inputs. Impaired loans (excluding PCI loans) - Nonaccrual loans and performing restructured loans are considered impaired for reporting purposes and are measured and recorded at fair value on a non-recurring basis. Nonaccrual Non-PCI loans with an unpaid principal balance over $100,000 and all performing restructured loans are reviewed individually for the amount of impairment, if any. Nonaccrual Non-PCI loans with an unpaid principal balance of $100,000 or less are evaluated for impairment collectively. The Company does not record loans at fair value on a recurring basis. However, from time to time, nonrecurring fair value adjustments to collateral dependent impaired loans are recorded based on either the current appraised value of the collateral, a Level 2 measurement, or management’s judgment and estimation of value reported on older appraisals that are then adjusted based on recent market trends, a Level 3 measurement. OREO - Fair value of OREO 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. Appraisals are required annually and may be updated more frequently as circumstances require and the fair value adjustments are made to OREO based on the updated appraised value of the property. Nonperforming loans held for sale - We reclassify certain nonperforming loans as held for sale when we decide to sell those loans. The fair value of nonperforming loans held for sale is generally based upon the quotes, bids or sales contract prices which approximate their fair value. Nonperforming loans held for sale are recorded at estimated fair value less anticipated liquidation cost. As of September 30, 2016 and December 31, 2015 , we did not have nonperforming loans held for sale, which are measured on a nonrecurring basis with Level 2 inputs. Assets and Liabilities Measured at Fair Value on a Recurring Basis As of September 30, 2016 and December 31, 2015 , assets and liabilities measured at fair value on a recurring basis are as follows: Level 1 Level 2 Level 3 Quoted Prices in Active Markets for Identical Assets Significant Observable Inputs with No Active Market with Identical Characteristics Significant Unobservable Inputs Balance (in thousands) September 30, 2016 Assets: Securities available for sale: Mortgage-backed securities $ — $ 243,245 $ — $ 243,245 Collateralized mortgage obligations — 84,213 — 84,213 U.S. government agency securities — 7,519 — 7,519 SBA loan pools securities — 4,545 — 4,545 Municipal bonds-tax exempt — 167,236 — 167,236 Municipal bonds-taxable — 13,925 — 13,925 Corporate bonds — 5,011 — 5,011 U.S. treasury securities 158 — — 158 Mutual funds 23,109 — — 23,109 Total securities available for sale $ 23,267 $ 525,694 $ — $ 548,961 December 31, 2015 Assets: Securities available for sale: Mortgage-backed securities $ — $ 284,381 $ — $ 284,381 Collateralized mortgage obligations — 96,986 — 96,986 U.S. government agency securities — 47,822 — 47,822 SBA loan pools securities — 63,266 — 63,266 Municipal bonds-tax exempt — 163,902 — 163,902 Municipal bonds-taxable — 14,033 — 14,033 Corporate bonds — 4,993 — 4,993 U.S. treasury securities 160 — — 160 Mutual funds 22,753 — — 22,753 Total securities available for sale $ 22,913 $ 675,383 $ — $ 698,296 Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis As of September 30, 2016 and December 31, 2015 , assets and liabilities measured at fair value on a non-recurring basis are as follows: Level 1 Level 2 Level 3 Quoted Prices in Active Markets for Identical Assets Significant Observable Inputs With No Active Market With Identical Characteristics Significant Unobservable Inputs Loss During the Nine Months Ended September 30, 2016 (in thousands) September 30, 2016 Assets: Impaired loans (excluding PCI loans) (1) $ — $ 14,590 $ 6,099 $ — OREO (2) $ — $ 10,971 $ — $ — Level 1 Level 2 Level 3 Quoted Prices in Active Markets for Identical Assets Significant Observable Inputs With No Active Market With Identical Characteristics Significant Unobservable Inputs Loss During the Twelve Months Ended December 31, 2015 (in thousands) December 31, 2015 Assets: Impaired loans (excluding PCI loans) (3) $ — $ 29,595 $ 1,044 $ 2,756 OREO (4) $ — $ 8,511 $ — $ — (1) Consist of real estate loans of $15.8 million , commercial and industrial loans of $4.2 million and consumer loans of $680,000 .

(3) Consist of real estate loans of $27.9 million , commercial and industrial loans of $1.0 million , and consumer loans of $1.7 million . (4) Consist of properties obtained from the foreclosure of commercial property loans of $6.6 million and residential property loans of $1.9 million . ASC 825, Financial Instruments , requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured on a recurring basis or non-recurring basis are discussed above. The estimated fair value of financial instruments has been determined by using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret market data in order to develop estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that we could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. The estimated fair values of financial instruments were as follows: September 30, 2016 Carrying Fair Value Amount Level 1 Level 2 Level 3 (in thousands) Financial assets: Cash and due from banks $ 130,197 $ 130,197 $ — $ — Securities available for sale 548,961 23,267 525,694 — Loans receivable, net of allowance for loan losses 3,513,687 — — 3,509,856 Loans held for sale 6,425 — 6,425 — Accrued interest receivable 10,160 10,160 — — FHLB stock 16,385 — 16,385 — Financial liabilities: Noninterest-bearing deposits 1,231,967 — 1,231,967 — Interest-bearing deposits 2,539,240 — — 2,579,750 Borrowings 73,888 — — 73,888 Accrued interest payable 2,444 2,444 — — Off-balance sheet items: Commitments to extend credit 330,116 — — 330,116 Standby letters of credit 7,793 — — 7,793 Commercial letters of credit 3,652 — — 3,652 December 31, 2015 Carrying Fair Value Amount Level 1 Level 2 Level 3 (in thousands) Financial assets: Cash and due from banks $ 164,364 $ 164,364 $ — $ — Securities available for sale 698,296 22,913 675,383 — Loans receivable, net of allowance for loan losses 3,140,381 — — 3,127,172 Loans held for sale 2,874 — 2,874 — Accrued interest receivable 9,501 9,501 — — FHLB stock 16,385 — 16,385 — FRB stock 14,098 — 14,098 — Financial liabilities: Noninterest-bearing deposits 1,155,518 — 1,155,518 — Interest-bearing deposits 2,354,458 — — 2,329,335 Borrowings 188,703 — — 188,703 Accrued interest payable 3,177 3,177 — — Off-balance sheet items: Commitments to extend credit 262,680 — — 262,680 Standby letters of credit 6,839 — — 6,839 Commercial letters of credit 4,018 — — 4,018 The methods and assumptions used to estimate the fair value of each class of financial instruments for which it was practicable to estimate that value are explained below: Cash and cash equivalents - The carrying amounts of cash and cash equivalents approximate fair value due to the short-term nature of these instruments (Level 1). Securities - The fair value of securities, consisting of securities available for sale, is generally obtained from market bids for similar or identical securities, from independent securities brokers or dealers, or from other model-based valuation techniques described above (Levels 1, 2 and 3). Loans receivable, net of allowance for loan losses - Loans receivable include Non-PCI loans, PCI loans and Non-PCI impaired loans. The fair value of Non-PCI loans receivable is estimated based on the discounted cash flow approach. The discount rate was derived from the associated yield curve plus spreads and reflects the offering rates offered by the Bank for loans with similar financial characteristics. Yield curves are constructed by product type using the Bank’s loan pricing model for like-quality credits. The discount rates used in the Bank’s model represent the rates the Bank would offer to current borrowers for like-quality credits. These rates could be different from what other financial institutions could offer for these loans. No adjustments have been made for changes in credit within the loan portfolio. It is our opinion that the allowance for loan losses relating to performing and nonperforming loans results in a fair valuation of such loans. Additionally, the fair value of our loans may differ significantly from the values that would have been used had a ready market existed for such loans and may differ materially from the values that we may ultimately realize (Level 3). The fair value of PCI loans receivable was estimated based on discounted expected cash flows. Increases in expected cash flows and improvements in the timing of cash flows over those previously estimated increase the amount of accretable yield and are recognized as an increase in yield and interest income prospectively. Decreases in the amount and delays in the timing of expected cash flows compared to those previously estimated decrease the amount of accretable yield and usually result in a provision for loan losses and the establishment of an allowance for loan losses (Level 3). The fair value of impaired loans (excluding PCI loans) is estimated based on the net realizable fair value of the collateral or the observable market price of the most recent sale or quoted price from loans held for sale. The Company does not record loans at fair value on a recurring basis. Nonrecurring fair value adjustments to collateral dependent impaired loans are recorded based on the current appraised value of the collateral (Level 3). Loans held for sale - Loans held for sale are carried at the lower of aggregate cost or fair market value, as determined based upon quotes, bids or sales contract prices, or as may be assessed based upon the fair value of the collateral which is obtained from recent real estate appraisals (Level 2). Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustment is typically significant and results in Level 3 classification of the inputs for determining fair value. Accrued interest receivable - The carrying amount of accrued interest receivable approximates its fair value (Level 1). FHLB and FRB stock - The carrying amounts of FHLB and FRB stock approximate fair value as such stock may be resold to the issuer at carrying value (Level 2). Noninterest-bearing deposits - The fair value of noninterest-bearing deposits is the amount payable on demand at the reporting date (Level 2). Interest-bearing deposits - The fair value of interest-bearing deposits, such as savings accounts, money market checking, and certificates of deposit, is estimated based on discounted cash flows. The cash flows for non-maturity deposits, including savings accounts and money market checking, are estimated based on their historical decaying experiences. The discount rate used for fair valuation is based on interest rates currently being offered by the Bank on comparable deposits as to amount and term (Level 3). Borrowings - Borrowings consist of FHLB advances, subordinated debentures and other borrowings. Discounted cash flows based on current market rates for borrowings with similar remaining maturities are used to estimate the fair value of borrowings (Level 3). Accrued interest payable - The carrying amount of accrued interest payable approximates its fair value (Level 1). Commitments to extend credit, standby letters of credit and commercial letters of credit - The fair values of commitments to extend credit and letters of credit are based upon the difference between the current value of similar loans and the price at which the Bank has committed to make the loans (Level 3).

Risks and Uncertainties [Abstract]
Off-Balance Sheet Commitments	Off-Balance Sheet Commitments The Bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk similar to the risk involved with on-balance sheet items recognized in the consolidated balance sheets. The Bank’s exposure to loan losses in the event of non-performance by the other party to commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for extending loan facilities to customers. The Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, was based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, premises and equipment, and income-producing or borrower-occupied properties. The following table shows the distribution of undisbursed loan commitments as of the dates indicated: September 30, 2016 December 31, 2015 (in thousands) Commitments to extend credit $ 330,116 $ 262,680 Standby letters of credit 7,793 6,839 Commercial letters of credit 3,652 4,018 Total undisbursed loan commitments $ 341,561 $ 273,537 The allowance for off-balance sheet items is maintained at a level believed to be sufficient to absorb probable losses related to these unfunded credit facilities. The determination of the allowance adequacy is based on periodic evaluations of the unfunded credit facilities including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. Net adjustments to the allowance for off-balance sheet items are included in other operating expenses. Activity in the allowance for loan off-balance sheet items was as follows for the periods indicated: Three Months Ended Nine Months Ended 2016 2015 2016 2015 (in thousands) Balance at beginning of period $ 1,475 $ 962 $ 986 $ 1,366 Provision (negative provision) 16 (406 ) 505 (810 ) Balance at end of period $ 1,491 $ 556 $ 1,491 $ 556
