Accounting Policies [Abstract]
Basis of Presentation	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. 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 March 31, 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 our 2015 Annual Report on Form 10-K.

Mortgage-backed securities and collateralized mortgage obligations are included in the table shown below based on their contractual maturities. However, their expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Mutual funds do not have contractual maturities. However, they are included in the table shown below as over ten years since the Company intends to hold these securities for at least this duration.

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 March 31, 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 March 31, 2016 and December 31, 2015 were not other-than-temporarily impaired, and therefore, no impairment charges as of March 31, 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 March 31, 2016 2015 (in thousands) Gross realized gains on sales of securities $ — $ 2,194 Gross realized losses on sales of securities — (10 ) Net realized gains on sales of securities $ — $ 2,184 Proceeds from sales of securities $ — $ 176,848 For the three months ended March 31, 2016 , there was no gain or loss included in earnings resulting from the sale of securities. For the three months ended March 31, 2015 , there was a $2.2 million net gain in earnings resulting from the sale of securities that had previously been recorded as net unrealized gains of $535,000 in comprehensive income. Securities available for sale with market values of $ 70.2 million and $ 72.0 million as of March 31, 2016 and December 31, 2015 , respectively, were pledged to secure public deposits and for other purposes as required or permitted by law.

Loans Held for Sale The following table includes the activity for loans held for sale (excluding PCI loans) by portfolio segment for the three months ended March 31, 2016 and 2015 : Real Estate Commercial and Industrial Total Non-PCI (in thousands) March 31, 2016 Loans held for sale, at beginning of period $ 840 $ 2,034 $ 2,874 Originations 6,473 5,679 12,152 Sales (5,488 ) (6,935 ) (12,423 ) Principal payoffs and amortization (1 ) (19 ) (20 ) Loans held for sale, at end of period $ 1,824 $ 759 $ 2,583 March 31, 2015 Loans held for sale, at beginning of period $ 3,323 $ 2,128 $ 5,451 Originations 16,927 6,181 23,108 Sales (13,014 ) (6,840 ) (19,854 ) Principal payoffs and amortization (10 ) (18 ) (28 ) Loans held for sale, at end of period $ 7,226 $ 1,451 $ 8,677 There was no reclassification of Non-PCI loans receivable to loans held for sale during the three months ended March 31, 2016 and 2015 . Allowance for Loan Losses Activity in the allowance for loan losses was as follows for the periods indicated: As of and for the Three Months Ended March 31, 2016 March 31, 2015 Non-PCI Loans PCI Loans Total Non-PCI Loans PCI Loans Total Allowance for loan losses: Balance at beginning of period $ 37,494 $ 5,441 $ 42,935 $ 51,640 $ 1,026 52,666 Charge-offs (637 ) — (637 ) (34 ) (52 ) (86 ) Recoveries on loans previously charged off 253 — 253 1,692 352 2,044 Net loan (charge-offs) recoveries (384 ) — (384 ) 1,658 300 1,958 (Negative provision) provision (1,729 ) 204 (1,525 ) (1,783 ) 110 (1,673 ) Balance at end of period $ 35,381 $ 5,645 $ 41,026 $ 51,515 $ 1,436 52,951 Management believes the allowance for loan losses is appropriate to provide for probable losses inherent in the loan portfolio. 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. The following table details the information on the allowance for loan losses by portfolio segment as of and for the three months ended March 31, 2016 and 2015 : Real Estate Commercial and Industrial Consumer Unallocated Total (in thousands) March 31, 2016 Allowance for loan losses on Non-PCI loans: Beginning balance $ 29,800 $ 7,081 $ 242 $ 371 $ 37,494 Charge-offs (535 ) (102 ) — — (637 ) Recoveries on loans previously charged off 93 160 — — 253 (Negative provision) provision (1,080 ) (850 ) 13 188 (1,729 ) Ending balance $ 28,278 $ 6,289 $ 255 $ 559 $ 35,381 Ending balance: individually evaluated for impairment $ 3,334 $ 759 $ — $ — $ 4,093 Ending balance: collectively evaluated for impairment $ 24,944 $ 5,530 $ 255 $ 559 $ 31,288 Non-PCI loans receivable: Ending balance $ 2,966,390 $ 295,471 $ 24,783 $ — $ 3,286,644 Ending balance: individually evaluated for impairment $ 25,595 $ 6,441 $ 700 $ — $ 32,736 Ending balance: collectively evaluated for impairment $ 2,940,795 $ 289,030 $ 24,083 $ — $ 3,253,908 Allowance for loan losses on PCI loans: Beginning balance $ 5,397 $ 42 $ 2 $ — $ 5,441 Provision 202 2 — — 204 Ending balance: acquired with deteriorated credit quality $ 5,599 $ 44 $ 2 $ — $ 5,645 PCI loans receivable $ 19,625 $ 161 $ 49 $ — $ 19,835 March 31, 2015 Allowance for loan losses on Non-PCI loans: Beginning balance $ 41,194 $ 9,142 $ 220 $ 1,084 $ 51,640 Charge-offs — (34 ) — — (34 ) Recoveries on loans previously charged off 32 1,660 — — 1,692 Provision (negative provision) 1,324 (2,982 ) (35 ) (90 ) (1,783 ) Ending balance $ 42,550 $ 7,786 $ 185 $ 994 $ 51,515 Ending balance: individually evaluated for impairment $ 3,386 $ 1,913 $ — $ — $ 5,299 Ending balance: collectively evaluated for impairment $ 39,164 $ 5,873 $ 185 $ 994 $ 46,216 Non-PCI loans receivable: Ending balance $ 2,499,323 $ 250,351 $ 25,942 $ — $ 2,775,616 Ending balance: individually evaluated for impairment $ 33,537 $ 11,570 $ 1,823 $ — $ 46,930 Ending balance: collectively evaluated for impairment $ 2,465,786 $ 238,781 $ 24,119 $ — $ 2,728,686 Allowance for loan losses on PCI loans: Beginning balance $ 895 $ 131 $ — $ — $ 1,026 Charge-offs (52 ) — — — (52 ) Recoveries on loans previously charged off — 352 — — 352 Provision (negative provision) 475 (365 ) — — 110 Ending balance: acquired with deteriorated credit quality $ 1,318 $ 118 $ — $ — $ 1,436 PCI loans receivable $ 40,616 $ 281 $ 44 $ — $ 40,941 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 their 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.

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 March 31, 2016 and December 31, 2015 , $ 0.9 million and $1.0 million , respectively, of reserves relating to these loans were included in the allowance for loan losses. The following table details TDRs (excluding PCI loans), disaggregated by loan class, for the three months ended March 31, 2016 and 2015 : March 31, 2016 March 31, 2015 Number of Pre- Post- Number of Pre- Post- (in thousands, except number of loans) Real estate loans: Commercial property Retail (1) 1 $ 21 $ 20 — $ — $ — Commercial and industrial loans: Commercial term (2) 2 214 209 4 543 508 Total Non-PCI TDR loans 3 $ 235 $ 229 4 $ 543 $ 508 (1) Includes a modification of $20,000 through a reduction of principal or accrued interest for the three months ended March 31, 2016 . (2) Includes modifications of $152,000 through payment deferrals and $57,000 through extensions of maturity for the three months ended March 31, 2016 , and modifications of $508,000 through extensions of maturity for the three months ended March 31, 2015. During the three months ended March 31, 2016 , we restructured monthly payments on three loans, with a net carrying value of $229,000 as of March 31, 2016 , through temporary payment structure modifications. 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. The following table details TDRs (excluding PCI loans) that defaulted subsequent to the modifications occurring within the previous 12 months, disaggregated by loan class, for the three months ended March 31, 2016 and 2015 , respectively: Three Months Ended March 31, 2016 March 31, 2015 Number of Loans Recorded Investment Number of Loans Recorded Investment (in thousands, except number of loans) Real estate loans: Commercial property Retail — $ — 1 $ 1,832 Gas station — — 1 1,990 Other 2 719 1 379 Commercial and industrial loans: Commercial term 1 30 — — Commercial lines of credit — — 1 124 Total Non-PCI TDR loans 3 $ 749 4 $ 4,325 Purchased Credit Impaired Loans As part of the acquisition of CBI, the Company purchased loans for which there was, at acquisition, evidence of deterioration of credit quality subsequent to origination and it was probable that all contractually required payments would not be collected. Outstanding balance of PCI loans, the undiscounted sum of all amounts including amounts deemed principal, interest, fees and penalties, were $ 29.5 million and $30.9 million , respectively as of March 31, 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 to be recognized. 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 collateral securing the loan. The Company recognizes "Disposition gain on Purchased Credit Impaired Loans" when the cash proceeds or the amount received are in excess of the loan's carrying amount. The removal of the loan from the loan pool and the recognition of disposition gains do not affect the then applicable loan pool accretable yield. The following table summarizes the changes in carrying value of PCI loans during the three months ended March 31, 2016 and 2015: Carrying Amount Accretable Yield (in thousands) Balance at January 1, 2016 $ 14,573 $ (5,944 ) Accretion 421 421 Payments received (811 ) — Disposal/transfer to OREO 211 — Change in expected cash flows, net — (578 ) Provision for credit losses (204 ) — Balance at March 31, 2016 $ 14,190 $ (6,101 ) Balance at January 1, 2015 $ 43,475 $ (11,025 ) Accretion 843 843 Payments received (5,425 ) — Disposal/transfer to OREO 722 — Change in expected cash flows, net — 376 Provision for credit losses (110 ) — Balance at March 31, 2015 $ 39,505 $ (9,806 ) As of March 31, 2016 and December 31, 2015, pass/pass-watch, special mention and classified PCI loans, disaggregated by loan class, were as follows: Pass/Pass-Watch Special Mention Classified Total Allowance Total (in thousands) March 31, 2016 Real estate loans: Commercial property Retail $ — $ — $ 4,264 $ 4,264 $ 421 $ 3,843 Hospitality 184 — 3,915 4,099 — 4,099 Gas station 85 166 4,362 4,613 484 4,129 Other — — 5,495 5,495 4,497 998 Residential property 991 — 163 1,154 197 957 Commercial and industrial loans: Commercial term — — 161 161 44 117 Consumer loans — — 49 49 2 47 Total PCI loans $ 1,260 $ 166 $ 18,409 $ 19,835 $ 5,645 $ 14,190 December 31, 2015 Real estate loans: Commercial property Retail $ — $ — $ 4,849 $ 4,849 $ 269 $ 4,580 Hospitality 186 — 3,894 4,080 88 3,992 Gas station — 176 4,116 4,292 477 3,815 Other — — 5,418 5,418 4,412 1,006 Residential property 999 — 158 1,157 151 1,006 Commercial and industrial loans: Commercial term — — 171 171 42 129 Consumer loans — — 47 47 2 45 Total PCI loans $ 1,185 $ 176 $ 18,653 $ 20,014 $ 5,441 $ 14,573 Loans accounted for as PCI are generally considered accruing and performing loans as 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. If the timing and amount of future cash flows is not reasonably estimable, the loans are classified as nonaccrual loans and interest income is not recognized until the timing and amount of future cash flows can be reasonably estimated. As of March 31, 2016 and December 31, 2015 , we had no PCI loans on nonaccrual status and included in the delinquency table below.

The FHLB advances were all overnight borrowings at March 31, 2016 and December 31, 2015. For the three months ended March 31, 2016 and 2015, interest expense on FHLB advances was $195,000 and $56,000 , respectively, and the weighted-average interest rate was 0.43 percent and 0.18 percent , respectively. The Bank maintains a secured credit facility with the FHLB, allowing the Bank to borrow on an overnight and term basis. The Bank had $472.7 million of loans pledged as collateral with the FHLB, which provides $422.5 million in borrowing capacity, of which $172.5 million remained available at March 31, 2016. The Bank also has $46.2 million in loans pledged with the FRB, which provides $29.6 million in available borrowing capacity through the Fed Discount Window.

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 $ 56,000 and $38,000 for the three months ended March 31, 2016 , and 2015 , respectively.

Earnings Per Share

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 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 March 31, 2016 March 31, 2015 (in thousands, except for share and per share data) Basic EPS: Net income $ 14,804 $ 11,054 Less: income allocated to unvested restricted shares 79 — Income allocated to common shares 14,725 11,054 Weighted-average shares for basic EPS 31,846,371 31,747,299 Basic EPS $ 0.46 $ 0.35 Effect of dilutive securities - options and unvested restricted stock 81,732 279,424 Diluted EPS: Income allocated to common shares $ 14,725 $ 11,054 Weighted-average shares for diluted EPS 31,928,103 32,026,723 Diluted EPS $ 0.46 $ 0.35 For the three months ended March 31, 2016 and 2015 , stock options of 109,750 and 138,725 , 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 System, the Office of the Comptroller of the Currency and the FDIC approved the Basel III regulatory capital framework and related Dodd-Frank Wall Street Reform and Consumer Protection Act changes. 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.

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 March 31, 2016 and December 31, 2015 , we had $2.6 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 March 31, 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 March 31, 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 March 31, 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) March 31, 2016 Assets: Securities available for sale: Mortgage-backed securities $ — $ 273,590 $ — $ 273,590 Collateralized mortgage obligations — 92,129 — 92,129 U.S. government agency securities — 40,040 — 40,040 SBA loan pools securities — 60,607 — 60,607 Municipal bonds-tax exempt — 166,126 — 166,126 Municipal bonds-taxable — 14,313 — 14,313 Corporate bonds — 4,998 — 4,998 U.S. treasury securities 160 — — 160 Mutual funds 23,069 — — 23,069 Total securities available for sale $ 23,229 $ 651,803 $ — $ 675,032 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 March 31, 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 Three Months Ended March 31, 2016 (in thousands) March 31, 2016 Assets: Impaired loans (excluding PCI loans) (1) $ — $ 21,619 $ 1,209 $ 646 OREO (2) $ — $ 9,411 $ — $ — 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) Consists of real estate loans of $21.8 million , commercial and industrial loans of $ $337 thousand and consumer loans of $700,000 .

(4) Consists of properties obtained from the foreclosure of commercial property loans of $6.6 million and residential property loans of $1.9 million . ASC 825 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: March 31, 2016 Carrying Fair Value Amount Level 1 Level 2 Level 3 (in thousands) Financial assets: Cash and due from banks $ 137,464 $ 137,464 $ — $ — Securities available for sale 675,032 23,229 651,803 — Loans receivable, net of allowance for loan losses 3,265,453 — — 3,264,239 Loans held for sale 2,583 — 2,583 — Accrued interest receivable 10,626 10,626 10,626 — — FHLB stock 16,385 — 16,385 — FRB stock 14,423 — 14,423 — Financial liabilities: Noninterest-bearing deposits 1,172,444 — 1,172,444 — Interest-bearing deposits 2,327,548 — — 2,342,580 Borrowings 268,759 — — 268,759 Accrued interest payable 3,249 3,249 — — Off-balance sheet items: Commitments to extend credit 349,931 — — 349,931 Standby letters of credit 7,943 — — 7,943 Commercial letters of credit 5,354 — — 5,354 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). Servicing assets or servicing liabilities - Servicing assets or servicing liabilities are carried at implied fair value. The fair values of the servicing assets or servicing liabilities are estimated by discounting future cash flows using market-based discount rates and prepayments speeds. The discount rate is based on the current U.S. Treasury yield curve, as published by the Department of the Treasury, plus a spread for the marketplace risk associated with these assets. (Level 3) 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: March 31, 2016 December 31, 2015 (in thousands) Commitments to extend credit $ 349,931 $ 262,680 Standby letters of credit 7,943 6,839 Commercial letters of credit 5,354 4,018 Total undisbursed loan commitments $ 363,228 $ 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: As of and for the Three Months Ended March 31, 2016 March 31, 2015 Allowance for off-balance sheet items: Balance at beginning of period $ 986 $ 1,366 Provision (negative provision) 234 (312 ) Balance at end of period $ 1,220 $ 1,054
