Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Hanmi Financial Corporation (“Hanmi Financial,” the “Company,” “we,” “us” or “our”) was formed as a holding company of Hanmi Bank (the “Bank”) and registered with the Securities and Exchange Commission under the Securities Exchange Act of 1934 in 2000. 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. On August 31, 2014, Hanmi Financial completed its acquisition of Central Bancorp, Inc., a Texas corporation (“CBI”). See Note 2 - Acquisition and Note 6 - Loans for accounting policies regarding purchased loans. During the second quarter of 2014, we sold two subsidiaries, Chun-Ha Insurance Services, Inc., a California corporation (“Chun-Ha”), and All World Insurance Services, Inc., a California corporation (“All World”). See Note 4 - Sale of Insurance Subsidiaries and Discontinued Operations. 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, 2015 , 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, 2014 (the “2014 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 fair value estimates of assets acquired and liabilities assumed in the CBI acquisition as discussed in Note 2 - Acquisition. The acquired assets and assumed liabilities of CBI were measured at their estimated fair values. The Company made significant estimates and exercised significant judgment in estimating fair values and accounting for such acquired assets and assumed liabilities. 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 2014 Annual Report on Form 10-K. During the second quarter of 2014, we adopted an accounting policy related to accounting for investments in low-income housing tax credit according to Financial Accounting Standards Board (“FASB”) ASU 2014-01 , Accounting for Investments in Qualified Affordable Housing Projects. See Note 3 - Accounting for Investments in Qualified Affordable Housing Projects.

Business Combinations [Abstract]
Acquisition	Acquisition Acquisition of Central Bancorp, Inc. On August 31, 2014 , Hanmi Financial completed its acquisition of CBI, the parent company of United Central Bank (“UCB”). In the merger with CBI, each share of CBI common stock was exchanged for $17.64 per share or $50.0 million in the aggregate. In addition, Hanmi Financial paid $28.7 million to redeem CBI preferred stock immediately prior to the consummation of the merger. The merger consideration was funded from consolidated cash of Hanmi Financial. At August 31, 2014, CBI had total assets, liabilities and net assets of $1.27 billion , $1.17 billion and $93.3 million respectively. Total loans and deposits were $297.3 million and $1.10 billion , respectively, at August 31, 2014 . CBI was headquartered in Garland, Texas and through UCB, operated 23 branch locations within Texas, Illinois, Virginia, New York, New Jersey and California. The combined companies operate as Hanmi Financial Corporation and Hanmi Bank, respectively, with banking operations under the Hanmi Bank brand. The acquisition was accounted for under the acquisition method of accounting pursuant to ASC 805, Business Combinations . The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the acquisition date. The consideration paid, assets acquired and liabilities assumed are summarized in the following table: (in thousands) Consideration paid: CBI Stockholders $ 50,000 Redemption of preferred stock and cumulative unpaid dividends 28,675 78,675 Assets acquired: Cash and cash equivalents 197,209 Securities available for sale 663,497 Loans 297,272 Premises and equipment 17,925 OREO 25,952 Income tax assets, net 12,011 Core deposit intangible 2,213 FDIC loss sharing asset 11,413 Bank-owned life insurance 18,296 Servicing assets 7,497 Other assets 14,636 Total assets acquired 1,267,921 Liabilities assumed: Deposits 1,098,997 Subordinated debentures 18,473 Rescinded stock obligation 15,485 FHLB advances 10,000 Servicing liabilities 6,039 Other liabilities 25,675 Total liabilities assumed 1,174,669 Total identifiable net assets $ 93,252 Bargain purchase gain, net of deferred taxes $ 14,577 The application of the acquisition method of accounting resulted in a bargain purchase gain of $14.6 million . The operations of CBI are included in our operating results since the acquisition date. Acquisition-related costs of $6.6 million for the year ended December 31, 2014 were expensed as incurred as merger and integration costs. These expenses are comprised primarily of system conversion costs and professional fees. For the three and nine months ended September 30, 2015 , acquisition costs of none and $1.7 million , respectively, were expensed as incurred as merger and integration costs. The $297.3 million estimated fair value of loans acquired from CBI was determined by utilizing a discounted cash flow methodology considering credit and interest rate risk. Cash flows were determined by estimating future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value based on a current market rate for similar loans. There was no carryover of CBI’s allowance for loan losses associated with the loans acquired as loans were initially recorded at fair value. The following table summarizes the accretable yield on the purchased credit impaired loans acquired from the CBI merger at August 31, 2014 . (in thousands) Undiscounted contractual cash flows $ 93,623 Nonaccretable discount (17,421 ) Undiscounted cash flow to be collected 76,202 Estimated fair value of PCI loans 65,346 Accretable yield $ 10,856 The core deposit intangible (“CDI”) of $2.2 million was recognized for the core deposits acquired from CBI. The CDI is amortized over its useful life of approximately ten years on an accelerated basis and reviewed for impairment at least quarterly. The amortization of the CDI for the three and nine months ended September 30, 2015 was $95,000 and $285,000 , respectively. The fair value of savings and transactional deposit accounts was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. Expected cash flows were utilized for fair value calculation of the certificates of deposit based on the contractual terms of the certificates of deposit and the cash flows were discounted based on a current market rate for certificates of deposit with corresponding maturities. The premium of $11.3 million was recognized for certificates of deposit acquired from CBI. The amortization of premium for the three and nine months ended September 30, 2015 were $1.4 million and $4.5 million , respectively. The fair value of subordinated debentures was determined by estimating projected future cash flows and discounting them at a market rate of interest. A discount of $8.3 million was recognized for subordinated debentures, which will be amortized over their contractual term. The amortization of discount for the three and nine months ended September 30, 2015 were $46,000 and $125,000 , respectively. Unaudited Pro Forma Results of Operations The following table presents our unaudited pro forma results of operations for the periods presented as if the CBI acquisition had been completed on January 1, 2014 . The unaudited pro forma results of operations include the historical accounts of Hanmi Financial and CBI and pro forma adjustments as may be required, including the amortization of intangibles with definite lives and the amortization or accretion of any premiums or discounts arising from fair value adjustments for assets acquired and liabilities assumed.

Accounting Changes and Error Corrections [Abstract]
Accounting for Investments in Qualified Affordable Housing Projects	Accounting for Investments in Qualified Affordable Housing Projects The Bank invests in qualified affordable housing projects (low income housing) and previously accounted for them under the equity method of accounting. The Bank recognized its share of partnership losses in other operating expenses with the tax benefits recognized in the income tax provision. In January 2014, the FASB issued ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects , which amends ASC 323 to provide the ability to elect the proportional amortization method with the amortization expense and tax benefits recognized through the income tax provision. This ASU is effective for the annual period beginning after December 15, 2014, with early adoption being permitted. The Bank elected to early adopt the provisions of the ASU in the second quarter of 2014 and elected the proportional amortization method as retrospective transition. This accounting change in the amortization methodology resulted in changes to account for amortization recognized in prior periods, which impacted the balance of tax credit investments and related tax accounts. The investment amortization expense is presented as a component of the income tax provision. The cumulative effect of the retrospective application of this accounting principle was a $1.1 million charge to stockholders' equity as of January 1, 2012. Net income in the three months ended March 31, 2014 decreased by $44,000 due to the change in accounting principle. The Bank determined that there were no events or changes in circumstances indicating that it is more likely than not that the carrying amount of the investment will not be realized. Therefore, no impairment was recognized as of September 30, 2015 or December 31, 2014 . The investment in low income housing was $19.5 million and $21.3 million as of September 30, 2015 and December 31, 2014 , respectively. The Bank’s unfunded commitments related to low income housing investments were $7.8 million and $11.9 million as of September 30, 2015 and December 31, 2014 , respectively. As a component of income tax expense, the Bank recognized amortizations of $592,000 and $1.7 million during the three and nine months ended September 30, 2015 , respectively and $592,000 and $1.0 million during the three and nine months ended September 30, 2014 , respectively. Tax credits and other benefits received from the tax expenses were $839,000 and $2.5 million during the three and nine months ended September 30, 2015 and $821,000 and $ 1.4 million during the three and nine months ended September 30, 2014 , respectively.

Discontinued Operations and Disposal Groups [Abstract]
Sale of Insurance Subsidiaries and Discontinued Operations	Sale of Insurance Subsidiaries and Discontinued Operations In June, 2014, Hanmi Financial sold its insurance subsidiaries, Chun-Ha and All World, and entered into a stock purchase agreement for their sale. The subsidiaries were classified as held for sale in April 2014 and accounted for as discontinued operations. The operations and cash flows of the businesses have been eliminated and in accordance with the provisions of ASC 205 , Presentation of Financial Statements , the results are reported as discontinued operations for all periods presented. Hanmi Financial completed the sale of its two insurance subsidiaries to Chunha Holding Corporation on June 30, 2014 when total assets and net assets of Chun-Ha and All World were $5.6 million and $3.3 million as of June 30, 2014 , respectively. The total sales price was $3.5 million , of which $2.0 million was paid upon signing. The remaining $1.5 million will be payable in three equal installments on each anniversary of the closing date through June 30, 2017 . The sale resulted in a $51,000 gain, offset by a $470,000 capital gain tax, a $14,000 operating loss and an $11,000 income tax expense. Consequently, the net loss from discontinued operations for the second quarter of 2014 was $444,000 , or $0.01 per diluted share. For the nine months ended September 30, 2014, the discontinued operations generated noninterest income, primarily in the line item for insurance commissions, of $2.7 million . They also incurred noninterest expense in various line items of $2.7 million for the nine months ended September 30, 2014 . Summarized financial information for our discontinued operations related to Chun-Ha and All World are as follows: June 30, 2014 (in thousands) Cash and cash equivalents $ 1,602 Premises and equipment, net 90 Other intangible assets, net 1,089 Other assets 2,855 Total assets $ 5,636 Income tax payable $ 415 Accrued expenses and other liabilities 1,878 Total liabilities $ 2,293 Net assets of discontinued operations $ 3,343 Nine Months Ended September 30, 2014 (in thousands) Noninterest loss $ (14 ) Gain on disposal 51 Income before taxes 37 Provision for income taxes 481 Net loss from discontinued operations $ (444 )

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, 2015 and December 31, 2014 . These securities have fluctuated in value since their purchase dates as market interest rates have fluctuated. FASB ASC 320 requires OTTI securities to be written down when fair value is below amortized cost in circumstances where: (1) an entity has the intent to sell a security; (2) it is more likely than not that an entity will be required to sell the security before recovery of its amortized cost basis; or (3) an entity does not expect to recover the entire amortized cost basis of the security. If an entity intends to sell a security or if it is more likely than not the entity will be required to sell the security before recovery, an OTTI write-down is recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value. If an entity does not intend to sell the security or it is not more likely than not that it will be required to sell the security before recovery, the OTTI write-down is separated into an amount representing credit loss, which is recognized in earnings, and the amount related to all other factors, which is recognized in other comprehensive income. 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 investments before the recovery of its 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, 2015 and December 31, 2014 were not other-than-temporarily impaired, and therefore, no impairment charges as of September 30, 2015 and December 31, 2014 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 September 30, Nine Months Ended September 30, 2015 2014 2015 2014 (in thousands) Gross realized gains on sales of securities $ 2,048 $ 67 $ 6,310 $ 1,853 Gross realized losses on sales of securities — — (166 ) (1 ) Net realized gains on sales of securities $ 2,048 $ 67 $ 6,144 $ 1,852 Proceeds from sales of securities $ 44,782 $ 9,778 $ 352,224 $ 135,834 Proceeds from called, matured and paid-down of securities $ 31,245 $ 24,591 $ 94,108 $ 61,145 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 three months ended September 30, 2014 , there was a $67,000 net gain in earnings resulting from the sale of securities that had previously been recorded as net unrealized gains of $23,000 in comprehensive income. For the nine months ended September 30, 2015 , there was a $6.1 million net gain in earnings resulting from the redemption and sale of securities that had previously been recorded as net unrealized gains of $2.0 million in comprehensive income. For the three months ended September 30, 2014 , there was a $1.9 million net gain in earnings resulting from the redemption and sale of securities that had previously been recorded as net unrealized losses of $498,000 in comprehensive income. Securities available for sale with market values of $71.6 million and $76.2 million as of September 30, 2015 and December 31, 2014 , respectively, were pledged to secure FHLB advances, public deposits and for other purposes as required or permitted by law.

Loans

Receivables [Abstract]
Loans	Loans The loan portfolio includes originated and purchased loans. Loans are originated by the Company with the intent to hold them for investment and are stated at the principal amount outstanding, net of unearned income. Unearned income includes deferred unamortized nonrefundable loan fees and direct loan origination costs. Net deferred fees or costs are recognized as an adjustment to interest income over the contractual life of the loans using the effective interest method or taken into income when the related loans are paid off or sold. The amortization of loan fees or costs is discontinued when a loan is placed on nonaccrual status. Interest income is recorded on an accrual basis in accordance with the terms of the respective loan and includes prepayment penalties. Purchased loans, which are loans we have acquired through our acquisition of other banks or purchased from other institutions, are stated at the principal amount outstanding, net of unearned discounts or unamortized premiums. All loans acquired in acquisitions are initially measured and recorded at their fair value on the acquisition date. A component of the initial fair value measurement is an estimate of the credit losses over the life of the purchased loans. Purchased loans are also evaluated for impairment as of the acquisition date and are accounted for as "acquired non-impaired" or "purchased credit impaired" loans. Purchased non-impaired loans are those loans for which there was no evidence of credit deterioration at their acquisition date and it was probable that we would be able to collect all contractually required payments. Purchased non-impaired loans, together with originated loans, are referred to as non-purchased credit impaired ("Non-PCI") loans. Purchase discounts or premiums on Non-PCI loans is recognized as an adjustment to interest income over the contractual life of such loans using the effective interest method or taken into income when the related loans are paid off or sold. Purchased credit impaired ("PCI") loans are accounted for in accordance with ASC Subtopic 310-30, " Loans and Debt Securities Acquired with Deteriorated Credit Quality." A purchased loan is deemed to be credit impaired when there is evidence of credit deterioration since its origination and it is probable at the acquisition date that we would be unable to collect all contractually required payments. We apply PCI loan accounting when we acquire loans deemed to be impaired. 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 Board of Directors and management review and approve the Bank’s loan policy and procedures on a regular basis to reflect issues such as regulatory and organizational structure changes, strategic planning revisions, concentrations of credit, loan delinquencies and nonperforming loans, problem loans, and policy adjustments. Real estate loans are loans secured by liens or interest in real estate, to provide purchase, construction, and refinance on real estate properties. Commercial and industrial loans consist of commercial term loans, commercial lines of credit, and Small Business Administration (“SBA”) loans. Consumer loans consist of auto loans, personal loans, and home equity lines of credit. We maintain management loan review and monitoring departments that review and monitor pass graded loans as well as problem loans to prevent further deterioration. The majority of the Bank’s loan portfolio consists of commercial real estate, and commercial and industrial loans. The Bank has been diversifying and monitoring commercial real estate loans based on property types, tightening underwriting standards and portfolio liquidity and management, and has not exceeded certain specified limits set forth in the Bank’s loan policy.

In addition, there was no reclassification from Non-PCI loans held for sale to Non-PCI loans receivable for the nine months ended September 30, 2014 . Activity in the allowance for loan losses and allowance for off-balance sheet items was as follows for the periods indicated: As of and for the Three Months Ended As of and for the Nine Months Ended September 30, 2015 September 30, 2014 (1) September 30, 2015 September 30, 2014 (1) Non-PCI Loans PCI Loans Total Non-PCI Loans PCI Loans Total (in thousands) Allowance for loan losses: Balance at beginning of period $ 49,468 $ 1,352 $ 50,820 $ 51,886 $ 51,640 $ 1,026 $ 52,666 $ 57,555 Charge-offs (1,748 ) — (1,748 ) (1,418 ) (3,004 ) — (3,004 ) (5,569 ) Recoveries on loans previously charged off 992 — 992 663 4,477 — 4,477 6,656 Net loan (charge-offs) recoveries (756 ) — (756 ) (755 ) 1,473 — 1,473 1,087 (Negative provision) provision charged to operating expense (5,490 ) 1,786 (3,704 ) 48 (9,891 ) $ 2,112 (7,779 ) (7,463 ) Balance at end of period $ 43,222 $ 3,138 $ 46,360 $ 51,179 $ 43,222 $ 3,138 $ 46,360 $ 51,179 Allowance for off-balance sheet items: Balance at beginning of period $ 962 $ — $ 962 $ 1,592 $ 1,366 $ — $ 1,366 $ 1,247 (Negative provision) provision charged to operating expense (406 ) — (406 ) (48 ) (810 ) $ — (810 ) 297 Balance at end of period $ 556 $ — $ 556 $ 1,544 $ 556 $ — $ 556 $ 1,544 (1) As of September 30, 2014, there was no allowance for loan losses associated with PCI loans. 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. As of September 30, 2015 and 2014 , the allowance for off-balance sheet items amounted to $556,000 and $ 1.5 million , respectively. Net adjustments to the allowance for off-balance sheet items are included in the other operating expenses. The Company determined that the net adjustments to the allowance for the off-balance sheet items should have been recorded to other noninterest expense rather than the provision for loan losses. Accordingly, the Company has revised the classification of the net adjustments from the provision for loan losses to other operating expenses in the Consolidated Statements of Income for the three and nine months ended September 30, 2014 as follows: As Previously Reported Effect of Change As Adjusted (in thousands) For the Three Months Ended September 30, 2014 Provision for loan losses $ — $ 48 $ 48 Other operating expenses $ 2,612 $ (48 ) $ 2,564 For the Nine Months Ended September 30, 2014 Provision for loan losses $ (7,166 ) $ (297 ) $ (7,463 ) Other operating expenses $ 6,883 $ 297 $ 7,180 The following table details the information on the allowance for loan losses by portfolio segment for the three months ended September 30, 2015 and 2014 : Real Estate Commercial and Industrial Consumer Unallocated Total (in thousands) September 30, 2015 Allowance for loan losses on Non-PCI loans: Beginning balance $ 39,898 $ 8,245 $ 172 $ 1,153 $ 49,468 Charge-offs (334 ) (1,414 ) — — (1,748 ) Recoveries on loans previously charged off 745 244 3 — 992 (Negative provision) provision (5,867 ) 700 (78 ) (245 ) (5,490 ) Ending balance $ 34,442 $ 7,775 $ 97 $ 908 $ 43,222 Ending balance: individually evaluated for impairment $ 3,500 $ 846 $ — $ — $ 4,346 Ending balance: collectively evaluated for impairment $ 30,942 $ 6,929 $ 97 $ 908 $ 38,876 Non-PCI loans receivable: Ending balance $ 2,714,645 $ 280,591 $ 24,691 $ — $ 3,019,927 Ending balance: individually evaluated for impairment $ 28,372 $ 7,851 $ 1,689 $ — $ 37,912 Ending balance: collectively evaluated for impairment $ 2,686,273 $ 272,740 $ 23,002 $ — $ 2,982,015 Allowance for loan losses on PCI loans: Beginning balance $ 1,289 $ 63 $ — $ — $ 1,352 Provision (negative provision) 1,830 (46 ) 2 — 1,786 Ending balance: acquired with deteriorated credit quality $ 3,119 $ 17 $ 2 $ — $ 3,138 PCI loans receivable: Ending balance: acquired with deteriorated credit quality $ 24,909 $ 193 $ 43 $ — $ 25,145 September 30, 2014 (1) Allowance for loan losses on Non-PCI loans: Beginning balance $ 40,303 $ 9,738 $ 540 $ 1,305 $ 51,886 Charge-offs (884 ) (499 ) (35 ) — (1,418 ) Recoveries on loans previously charged off 293 365 5 — 663 Provision (negative provision) 179 260 (186 ) (205 ) 48 Ending balance $ 39,891 $ 9,864 $ 324 $ 1,100 $ 51,179 Ending balance: individually evaluated for impairment $ 2,027 $ 3,757 $ — $ — $ 5,784 Ending balance: collectively evaluated for impairment $ 37,864 $ 6,107 $ 324 $ 1,100 $ 45,395 Non-PCI loans receivable: Ending balance $ 2,348,366 $ 234,975 $ 28,905 $ — $ 2,612,246 Ending balance: individually evaluated for impairment $ 35,654 $ 11,970 $ 1,758 $ — $ 49,382 Ending balance: collectively evaluated for impairment $ 2,312,712 $ 223,005 $ 27,147 $ — $ 2,562,864 (1) As of September 30, 2014, there was no allowance for loan losses associated with PCI loans.

Credit 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 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.

Debt Disclosure [Abstract]
Subordinated Debentures and Rescinded Stock Obligation	Subordinated Debentures and Rescinded Stock Obligation Subordinated Debentures During the third quarter of 2014, the Company assumed CBI’s Junior Subordinated Deferrable Interest Debentures (“Subordinated Debentures”) with an unpaid principal balance of $26.8 million and an estimated fair value of $18.5 million . The $8.3 million discount will be amortized to interest expense over the remaining term. In December 2005, a trust was formed by CBI 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 Subordinated Debentures. The Subordinated Debentures will mature on December 31, 2035 , however, the Bank 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 was $ 46,000 and $125,000 for the three and nine months ended September 30, 2015 , respectively. Rescinded Stock Obligation Hanmi Financial assumed a rescinded stock obligation of $15.5 million and related accrued interest payable of $4.5 million at the closing date of the CBI acquisition. The obligation resulted from the issuance of CBI common shares that CBI was not legally authorized to issue in 2010 and 2009. Interest had been accrued on the obligation at statutory interest rates that vary from state to state. As of September 30, 2015, the rescinded stock obligation and related accrued interest payable have been paid in full. The rescinded stock obligation and accrued interest as of December 31, 2014 were $933,000 and $288,000 , respectively, as of December 31, 2014 .

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Stockholders’ Equity Stock Warrants As part of an agreement dated as of July 27, 2010 with Cappello Capital Corp., the placement agent in connection with our best efforts offering and the financial advisor in connection with our completed rights offering, we issued warrants to purchase 250,000 shares of our common stock for services performed. The warrants had an exercise price of $9.60 per share. According to the agreement, the warrants vested on October 14, 2010 and were exercisable until their expiration on October 14, 2015 . The Company followed the guidance of FASB ASC Topic 815-40, Derivatives and Hedging—Contracts in Entity’s Own Stock, which established a framework for determining whether certain freestanding and embedded instruments are indexed to a company’s own stock for purposes of evaluation of the accounting for such instruments under existing accounting literature. Under GAAP, the issuer is required to measure the fair value of the equity instruments in the transaction as of the earlier of (i) the date at which a commitment for performance by the counterparty to earn the equity instruments is reached or (ii) the date at which the counterparty’s performance is complete. The fair value of the warrants at the date of issuance totaling $ 2.0 million was recorded as a liability and a cost of equity, which was determined by the Black-Scholes option pricing model. The expected stock volatility was based on historical volatility of our common stock over the expected term of the warrants. We used a weighted average expected stock volatility of 111.46 percent. The expected life assumption was based on the contract term of five years . The dividend yield of zero was based on the fact that we had no intention to pay cash dividends for the term at the grant date. The risk free rate of 2.07 percent used for the warrants was equal to the zero coupon rate in effect at the time of the grant. During the years of 2012, 2013 and 2014, all the stock warrants were exercised and there were no outstanding stock warrants as of December 31, 2014 .

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 Federal Deposit Insurance Corporation 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. Additionally, a new rule on the capital conservation buffer will be implemented beginning January 1, 2016. Under the final rules, institutions are subject to limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses if certain capital levels fall below newly required amounts. The rules became effective January 1, 2015 for smaller, non-complex banking organizations with full implementation of certain deductions and adjustments to regulatory capital through January 1, 2019. All prior period data is based on Basel I rules. The capital ratios of Hanmi Financial and the Bank as of September 30, 2015 and December 31, 2014 were as follows: Actual Minimum Regulatory Requirement Minimum to Be Categorized as “Well Capitalized” Amount Ratio Amount Ratio Amount Ratio (in thousands) September 30, 2015 Total capital (to risk-weighted assets): Hanmi Financial $ 487,613 14.75 % $ 264,425 8.00 % N/A N/A Hanmi Bank $ 484,968 14.69 % $ 264,078 8.00 % $ 330,097 10.00 % Tier 1 capital (to risk-weighted assets): Hanmi Financial $ 445,955 13.49 % $ 198,319 6.00 % N/A N/A Hanmi Bank $ 443,364 13.43 % $ 198,058 6.00 % $ 264,078 8.00 % Common equity Tier 1 capital (to risk-weighted assets): Hanmi Financial $ 445,955 13.49 % $ 148,739 4.50 % N/A N/A Hanmi Bank $ 443,364 13.43 % $ 148,544 4.50 % $ 214,563 6.5 % Tier 1 capital (to average assets): Hanmi Financial $ 445,955 11.19 % $ 159,401 4.00 % N/A N/A Hanmi Bank $ 443,364 11.14 % $ 159,196 4.00 % $ 198,995 5.00 % December 31, 2014 Total capital (to risk-weighted assets): Hanmi Financial $ 493,598 15.89 % $ 248,501 8.00 % N/A N/A Hanmi Bank $ 470,934 15.18 % $ 248,157 8.00 % $ 310,196 10.00 % Tier 1 capital (to risk-weighted assets): Hanmi Financial $ 454,582 14.63 % $ 124,250 4.00 % N/A N/A Hanmi Bank $ 431,971 13.93 % $ 124,078 4.00 % $ 186,118 6.00 % Tier 1 capital (to average assets): Hanmi Financial $ 454,582 10.91 % $ 166,600 4.00 % N/A N/A Hanmi Bank $ 431,971 10.39 % $ 166,332 4.00 % $ 207,915 5.00 %

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair Value Measurements FASB 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 other intangible assets, 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 not 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 bonds is determined based on a proprietary model maintained by the broker-dealers. 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. SBA loans held for sale - SBA loans held for sale are carried at the lower of cost or fair value. As of September 30, 2015 and December 31, 2014 , we had $4.9 million and $5.5 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, 2015 , 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, 2015 and December 31, 2014 , 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, 2015 and December 31, 2014 , 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, 2015 Assets: Securities available for sale: Mortgage-backed securities $ — $ 324,504 $ — $ 324,504 Collateralized mortgage obligations — 116,314 — 116,314 U.S. government agency securities — 57,674 — 57,674 SBA loan pools securities — 68,301 — 68,301 Municipal bonds-tax exempt — 48,001 — 48,001 Municipal bonds-taxable — 14,372 — 14,372 Corporate bonds — 17,005 — 17,005 U.S. treasury securities 162 — — 162 Other securities 23,007 — — 23,007 Total securities available for sale $ 23,169 $ 646,171 $ — $ 669,340 December 31, 2014 Assets: Securities available for sale: Mortgage-backed securities $ — $ 573,286 $ — $ 573,286 Collateralized mortgage obligations — 188,047 — 188,047 U.S. government agency securities (1) — 128,207 — 128,207 SBA loan pools securities — 109,447 — 109,447 Municipal bonds-tax exempt — 3,681 709 4,390 Municipal bonds-taxable — 16,922 — 16,922 Corporate bonds — 16,948 — 16,948 U.S. treasury securities 163 — — 163 Other securities (2) 22,893 — — 22,893 Equity securities — — 414 414 Total securities available for sale $ 23,056 $ 1,036,538 $ 1,123 $ 1,060,717 (1) U.S. government agency securities of $128.2 million were reclassified as level 2 rather than level 1 as originally classified due to significant other observable inputs other than quoted prices for identical assets in active markets. (2) Other securities of $22.9 million were reclassified as level 1 rather than level 2 as originally classified due to the availability of quoted prices in active markets of the holdings. The table below presents a reconciliation and income statement classification of gains and losses for all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the nine months ended September 30, 2015 : Beginning Balance as of January 1, 2015 Purchases, Issuances and Settlement Realized Gains or (Losses) in Earnings Unrealized Gains or Losses in Other Comprehensive Income Ending Balance as of September 30, 2015 (in thousands) Assets: Municipal bonds-tax exempt (1) $ 709 $ (709 ) $ — $ — $ — Equity securities (2) $ 414 $ (339 ) $ (75 ) $ — $ — (1) A zero coupon tax credit municipal bond matured during the first quarter of 2015.

During the second quarter of 2015, one equity security with a book value of $200,000 with a fair value of $200,000 as of December 31, 2014 was sold at $75,000 loss and the other equity security with a book value of $250,000 with a fair value of $214,000 as of December 31, 2014 was reclassified to other assets. Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis As of September 30, 2015 and December 31, 2014 , 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, 2015 (in thousands) September 30, 2015 Assets: Impaired loans (excluding PCI loans) (1) $ — $ 24,794 $ 1,202 $ 1,985 OREO (2) $ — $ 13,249 $ — $ 444 Level 1 Level 2 Level 3 Quoted Prices in Significant Significant Loss During the Twelve Months Ended December 31, 2014 (in thousands) December 31, 2014 Assets: Impaired loans (excluding PCI loans) (3) $ — $ 32,171 $ 781 $ 2,774 OREO (4) $ — $ 15,790 $ — $ — (1) Consists of real estate loans of $ 23.4 million , commercial and industrial loans of $896,000 , and consumer loans of $1.7 million .

(3) Consists of real estate loans of $ 30.0 million , commercial and industrial loans of $1.2 million and consumer loans of $1.7 million . (4) Consists of properties obtained from the foreclosure of commercial property loans of $13.2 million and residential property loans of $2.6 million . FASB 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: September 30, 2015 Carrying Fair Value Amount Level 1 Level 2 Level 3 (in thousands) Financial assets: Cash and due from banks $ 235,342 $ 235,342 $ — $ — Securities available for sale 669,340 23,169 646,171 — Loans receivable, net of allowance for loan losses 2,998,712 — — 3,006,747 Loans held for sale 4,871 — 4,871 — Accrued interest receivable 8,722 8,722 — — Servicing assets 11,986 — — 11,986 FHLB stock 16,385 — 16,385 — FRB stock 14,098 — 14,098 — Financial liabilities: Noninterest-bearing deposits 1,114,621 — 1,114,621 — Interest-bearing deposits 2,404,073 — — 2,404,110 Servicing liabilities 5,176 — — 5,176 Borrowings 168,669 — — 168,669 Accrued interest payable 2,985 2,985 — — Off-balance sheet items: Commitments to extend credit 314,303 — — 314,303 Standby letters of credit 5,603 — — 5,603 December 31, 2014 Carrying Fair Value Amount Level 1 Level 2 Level 3 (in thousands) Financial assets: Cash and due from banks $ 158,320 $ 158,320 $ — $ — Securities available for sale (1) 1,060,717 23,056 1,036,538 1,123 Loans receivable, net of allowance for loan losses 2,735,832 — — 2,738,401 Loans held for sale 5,451 — 5,451 — Accrued interest receivable 9,749 9,749 — — Servicing assets 13,773 — — 13,773 FHLB stock 17,580 — 17,580 — FRB stock 12,273 — 12,273 — Financial liabilities: Noninterest-bearing deposits 1,022,972 — 1,022,972 — Interest-bearing deposits 2,533,774 — — 2,528,304 Servicing liabilities 5,971 — — 5,971 Borrowings 168,544 — — 149,983 Accrued interest payable 3,450 3,450 — — Off-balance sheet items: Commitments to extend credit 309,584 — — 309,584 Standby letters of credit 8,982 — — 8,982 (1) Level 1 and Level 2 previously reported as $128.4 million and $931.2 million , respectively. U.S. government agency securities of $128.2 million were reclassified as Level 2 rather than Level 1 as originally classified due to significant other observable inputs other than quoted prices for identical assets in active markets. Other securities of $22.9 million were reclassified as Level 1 rather than Level 2 as originally classified due to the availability of quoted prices in active markets of the holdings. 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). Subsequent to the issuance of the Company's consolidated financial statements, the Company determined that investments in FHLB and FRB stock of $17.6 million and $12.3 million , respectively, should be classified as Level 2 rather than Level 1 as originally classified as ownership of these investments is restricted to member banks, the securities are non-marketable equity investments and purchases and sales of these securities are at par with the issuer. Accordingly, the Company has revised the classification of these investments from Level 1 to Level 2 in the table of fair value measurements as of December 31, 2014. 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 and standby letters of credit - The fair values of commitments to extend credit and standby 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).

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. Unvested restricted stock is excluded from the calculation of weighted-average number of common shares for basic EPS. 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 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 (in thousands, except for share and per share data) September 30, 2015 Basic EPS Net income $ 13,959 $ 38,997 Less: income allocated to unvested restricted shares 78 78 Income allocated to common shares 13,881 38,919 Weighted-average shares for basic EPS 31,799,573 31,774,047 Basic EPS $ 0.44 $ 1.22 Diluted EPS Income allocated to common shares $ 13,881 $ 38,919 Weighted-average shares for diluted EPS 31,909,808 31,855,024 Diluted EPS $ 0.44 $ 1.22 Three Months Ended Nine Months Ended Net Income (Numerator) Weighted-Average Shares (Denominator) Per Share Amount Net Income (Numerator) Weighted-Average Shares (Denominator) Per Share Amount (in thousands, except share and per share data) September 30, 2014 Basic EPS Income from continuing operations, net of tax $ 21,800 31,708,581 $ 0.69 $ 44,276 31,683,288 $ 1.39 Income from discontinued operations, net of tax — 31,708,581 — (444 ) 31,683,288 (0.01 ) Basic EPS $ 21,800 31,708,581 $ 0.69 $ 43,832 31,683,288 $ 1.38 Effect of dilutive securities - options and unvested restricted stock 292,838 284,588 Diluted EPS Income from continuing operations, net of tax $ 21,800 32,001,419 $ 0.68 $ 44,276 31,967,876 $ 1.39 Income from discontinued operations, net of tax — 32,001,419 — (444 ) 31,967,876 (0.01 ) Diluted EPS $ 21,800 32,001,419 $ 0.68 $ 43,832 31,967,876 $ 1.38 For the three and nine months ended September 30, 2015 stock options totaling 29,000 and 57,000 , respectively, were not included in the computation of diluted EPS.

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, 2015 December 31, 2014 (in thousands) Commitments to extend credit $ 314,317 $ 309,584 Standby letters of credit 5,603 8,982 Commercial letters of credit 3,949 7,046 Total undisbursed loan commitments $ 323,869 $ 325,612

Liquidity [Abstract]
Liquidity	Liquidity Hanmi Financial Management believes that Hanmi Financial, on a stand-alone basis, has adequate liquid assets to meet its operating cash needs through September 30, 2016 . Hanmi Bank The principal objective of our liquidity management program is to maintain the Bank’s ability to meet the day-to-day cash flow requirements of our customers who either wish to withdraw funds or to draw upon credit facilities to meet their cash needs. Management believes that the Bank, on a stand-alone basis, has adequate liquid assets to meet its current obligations. The Bank’s primary funding source will continue to be deposits originating from its branch platform. The Bank’s wholesale funds historically consisted of FHLB advances and brokered deposits. As of September 30, 2015 , the Bank had $99,000 of brokered deposits assumed in the CBI acquisition. We monitor the sources and uses of funds on a regular basis to maintain an acceptable liquidity position. The Bank’s primary source of borrowings is the FHLB, from which the Bank is eligible to borrow up to 30 percent of its assets. As of September 30, 2015 , the total borrowing capacity available based on pledged collateral and the remaining available borrowing capacity were $501.1 million and $351.1 million , respectively, compared to $649.5 million and $499.5 million , respectively, as of December 31, 2014 . The Bank’s FHLB borrowings as of September 30, 2015 and December 31, 2014 remained the same at $150.0 million , which represented 3.56 percent and 3.54 percent of assets as of September 30, 2015 and December 31, 2014 , respectively. The amount that the FHLB is willing to advance differs based on the quality and character of qualifying collateral pledged by the Bank, and the advance rates for qualifying collateral may be adjusted upwards or downwards by the FHLB from time to time. To the extent deposit renewals and deposit growth are not sufficient to fund maturing and withdrawable deposits, repay maturing borrowings, fund existing and future loans and securities and otherwise fund working capital needs and capital expenditures, the Bank may utilize the remaining borrowing capacity from its FHLB borrowing arrangement. As a means of augmenting its liquidity, the Bank had an available borrowing source of $35.9 million from the Federal Reserve Discount Window, to which the Bank pledged loans with a carrying value of $49.9 million , and had no borrowings as of September 30, 2015 . The Bank has a line of credit with Raymond James & Associates, Inc. for repurchase agreements up to $100.0 million . The Bank established unsecured federal funds lines of credit totaling $95.0 million from three financial institutions to support short-term liquidity. The Bank has Contingency Funding Plans (“CFPs”) designed to ensure that liquidity sources are sufficient to meet its ongoing obligations and commitments, particularly in the event of a liquidity contraction. The CFPs are designed to examine and quantify its liquidity under various “stress” scenarios. Furthermore, the CFPs provide a framework for management and other critical personnel to follow in the event of a liquidity contraction or in anticipation of such an event. The CFPs address authority for activation and decision making, liquidity options and the responsibilities of key departments in the event of a liquidity contraction.
